Quality Tour Guide Audio System & Wireless Tour Guide System Factory

When foreign customers purchase wireless audio guide devices, the most challenging part is not choosing the model, but worrying about selecting a small manufacturer - the equipment breaks down after half a year, and there's no one to provide after-sales service; the voltage is incompatible, and the device can't be used once it's received; even it hasn't passed international certification, and the clearance process gets stuck directly. In fact, the core of choosing an audio guide device is not comparing parameters or prices; it's first choosing the right brand and manufacturer. After all, reliable manufacturers can help you avoid 80% of the pitfalls.   Ⅰ.When foreign customers choose a manufacturer, these points are more important than price   When foreign customers purchase over a distance, they can't inspect the factory in person. When choosing a manufacturer, they look at 4 hard indicators, which are much more reliable than guessing parameters randomly.   1. Complete qualification certificates are necessary, making clearance and use convenient   Small manufacturers are most likely to have problems with qualifications. Either they haven't passed international certification or the certificates are forged. For foreign customers, at least they should ensure that the manufacturer has EU CE and RoHS certifications - these are the "passports" for the product to enter most countries in Europe, Southeast Asia, etc. Without these certificates, the clearance process is likely to be blocked, resulting in heavy losses.   Yingmi started its foreign trade business in 2010 and passed EU CE and RoHS certifications. Later, it also obtained the title of a national high-tech enterprise and a big data enterprise, and was listed on the Anhui Science and Technology Innovation Board. More strictly, each device undergoes two-way standard testing by China CMA and CNAS, and is exported to dozens of countries such as France, Germany, Malaysia, Indonesia, etc., with no clearance issues.   2.Have independent production capabilities, and quality can be controlled   Many small manufacturers do not produce themselves and rely on outsourcing assembly. The equipment has poor compatibility and unstable quality. The sound quality and battery life of today's batch and tomorrow's batch are different. Reliable manufacturers must have their own production system, from R&D to production, which is fully controllable throughout the process.   Yingmi invested in the SMT assembly factory in Hefei, Shoucheng Electronics, in 2018, achieving independent production of PCBA and having 4 automated SMT production lines. From chip selection, hardware assembly to final product testing, it is fully controlled by itself, unlike outsourcing manufacturers who are "out of control". More importantly, Yingmi has the 7S quality control system, and each device must undergo 5 strict tests (high temperature, low temperature, vibration, sound quality, battery life), with very low complaint rates during export over many years.   3.Strong technical capabilities are necessary, and they can adapt to different scenarios   The core of the audio guide device is technology. Small manufacturers do not have a R&D team and can only copy the appearance. The core technology relies on copying, and the sound quality and battery life are either poor in interference resistance or poor. Good manufacturers must have their own core patents that can optimize technology for different scenarios.   Yingmi has 4 core national patent technologies, such as SOC embedded integrated digital filtering and noise reduction technology, which can filter out noise in noisy environments, making the sound quality purer; PMU safe intelligent lithium battery power management technology, which can precisely control power and avoid false battery life marking; and Ergo ergonomic design, making the device more comfortable to wear. These technologies are not just theoretical but have been verified in high-end scenarios such as the Shanghai Cooperation Organization meeting and the International Museum Forum.   4.Complete foreign trade services are important, and details matter   When foreign customers purchase, they are most worried about "no one to handle after-sales service". Good manufacturers not only need good products but also have complete foreign trade services - such as supporting wide voltage, providing multilingual services, and prompt after-sales response.   Yingmi's detailed services are very considerate: All the charging modules of the devices support wide voltage input, whether it's 220V in Europe or 110V in the Americas, it can be used once received, without the need to buy a voltage converter; equipped with HM8.0 multilingual sharing platform, with a standard of 8 languages, and can be customized for small languages; Post-sale services include 9G full lifecycle support, quick response within 90 seconds before purchase, remote guidance to solve problems, and even if repair is needed, the product can be sent back to the factory and repaired within 10 working days.   II. Why Yingmi is the preferred choice for international customers? It meets the needs from both products and services.   Yingmi has been exporting globally not just because of low prices, but because its products, technologies, and services are fully adapted to the needs of foreign customers. Every detail has been thought out for the customers.   1. Product coverage for all scenarios   Different scenarios require different audio guides. For scenic spots, they need to be lightweight and have long battery life. For meetings, they need good sound quality and resistance to interference. For factories, they need dust-proof and heat-resistant properties. Yingmi's product line is extremely comprehensive. No matter what scenario it is, there will be a precise and suitable model.   For example, the E8 all-in-one audio guide is suitable for meetings. It weighs only 16 grams and is fashionable and high-end. The SOC noise reduction technology ensures the sound quality, and the 4GFSK anti-interference technology avoids interference among multiple teams. For scenic spots, the R8 ear-mounted audio guide is suitable. The Ergo ergonomic non-in-the-ear design makes it comfortable to wear for a whole day without causing ear pain, and it also solves the hygiene problem. For factories and noisy exhibition halls, the 008A audio guide is suitable. Its wall-penetrating effect is first-class, and the signal distance can reach up to 280 meters, allowing clear hearing at long distances. For museums with dense exhibits, the C7 touch navigation device is suitable, which can solve the problem of close-range interference.   2.Technology adapted to international scenarios, with full details   The usage scenarios of foreign customers are complex. Yingmi's technologies have been optimized for specific scenarios. For example, for scenarios where multiple teams use the equipment simultaneously, the 200k ultra-small channel bandwidth technology is used to achieve 100 independent channels, even if 100 groups of delegations are active at the same time, there will be no interference. For multilingual needs, the sound quality algorithm is optimized. Whether it's the Arabic tone or the Thai final sound, it can be clearly reproduced. For hot and dusty Middle Eastern scenarios, the equipment is treated for dust-proof and heat resistance to ensure stable battery life and sound quality.   III. Three additional details that make Yingmi particularly appealing to foreign customers   In addition to the above core advantages, Yingmi has three additional details that particularly impress foreign customers.   First, it supports small batch purchases without stockpiling. Many foreign customers have small initial demands, but small manufacturers often require large orders, increasing financial pressure. Yingmi can handle small batches of both basic models and customized models. Even 10 units can be customized with languages, which is particularly suitable for start-up enterprises or small scenic spots.   Second, it provides free sample testing. Foreign customers are worried that the equipment may not be suitable for their scenarios. Yingmi can send samples for free, allowing customers to test the sound quality, battery life, and anti-interference performance in the actual environment. They can place an order after being satisfied, with no risks.   Third, it offers lifetime guarantee services. Even if the equipment has problems after several years of use, it can contact Yingmi's after-sales service for free technical support and repair services. There is no need to purchase again, which is more cost-effective.   Conclusion   For foreign customers, choosing a wireless guide device is not a "one-time transaction", but a long-term partnership. Choosing the right manufacturer not only allows you to obtain reliable products with high quality, but also saves you from various troubles such as customs clearance, after-sales service, and compatibility issues.   With years of industry experience, independent production capabilities, products suitable for all scenarios, and comprehensive foreign trade services, Yingmi has become the choice of customers in dozens of countries around the world. If you are still struggling to decide which manufacturer to choose, you might as well try the samples of Yingmi. Whether they are good or not, you will know after testing. After all, reliable manufacturers are never afraid of the tests from customers.   Product Model Target Scenarios Core Features Yingmi E8 All-in-One Audio Guide International conferences, high-end events Lightweight (16g), fashionable design   SOC noise reduction technology (pure sound quality)   4GFSK anti-interference technology (no cross-team disruption) Yingmi R8 Ear-Mounted Audio Guide Scenic spots, daily tour groups Ergo ergonomic non-in-ear design (comfortable for all-day wear, hygienic)   Long battery life   Suitable for large tourist flows Yingmi 008A Audio Guide Factories, noisy exhibition halls Superior wall-penetrating effect   Max signal distance of 280 meters (clear long-distance audio)    Dust-proof and heat-resistant Yingmi C7 Touch Navigation Device Museums, exhibition halls with dense exhibits Touch-controlled navigation   Solves short-range interference issues   Precise exhibit matching   FAQ   Q1: Can Yingmi products be exported to our country?

Whether you are visiting famous mountains and rivers, ancient villages and towns, or exploring historical scenic spots, the beautiful scenery in front of your eyes is undoubtedly attractive, but the legends hidden in the mountains and waters, the stories behind the buildings, and the little wisdom in the folk customs are the most interesting parts of the scenic spots. However, many tourists have encountered such frustrating situations: when following a tour group for the tour, the noise is very loud and the tour guide's words are almost impossible to hear clearly, and they often can't keep up with the group; when traveling independently, facing the unfamiliar scenery, you can only look at the introduction signs and have no way to learn more about the background; sometimes several tour groups gather together, and the tour guide's explanations mix together, making it impossible for people to enjoy the scenery, and the entire enjoyable tour experience is ruined. And the tourist wireless guide device can precisely solve these problems, allowing everyone to understand clearly and hear clearly, and have a more enjoyable experience.   Ⅰ.Have you also encountered these annoying problems in scenic spot tours?   1.Listening to explanations in a crowded situation? Traditional methods really "can't hear clearly, can't keep up"   In popular scenic spots, the tour guide holds a loudspeaker and shouts, and the sound is easily covered by the noise of the crowd. Back-row tourists basically can't hear what the tour guide is saying, and can only pick up a few scattered sentences. When encountering narrow roads or viewing platforms, the team disperses, and the tour guide has to stop and wait, which not only wastes time but also makes the experience not smooth. This "passive listening, difficult to keep up" traditional explanation method makes many people miss the opportunity to understand the cultural heritage of the scenic spots.   No clue when traveling independently? The stories behind the beautiful scenery "can't be heard" Nowadays, more and more people prefer independent travel, but without professional explanations to guide, when facing unfamiliar historical buildings and natural landscapes, most can only take photos and leave. The information on the introduction signs is just a few sentences, and checking information with a mobile phone breaks the immersion of the tour. Many historical anecdotes, geographical knowledge, and folk customs hidden behind the beautiful scenery are thus missed.   2.When several tour groups gather together? The explanation sounds "too noisy"   In popular scenic spots or exhibition halls, it is often possible to encounter several tour groups visiting simultaneously. The explanations of different tour guides are mixed through amplification equipment, making it chaotic, not only making it impossible to focus on the explanation of one's own team, but also disrupting the tranquility of the scenic spot. The tour experience is greatly reduced.   Ⅱ.Solution: Three types of wireless guide devices, suitable for different tour scenarios   1.For group travel choose this: Wireless team guide system, clear without disturbing   If it is a tour group of 30 people or more, a study tour group, or an enterprise investigation team, the wireless team guide system is definitely a must-have. Yingmi's 008A wireless team guide device uses reliable wireless amplification technology and has strong penetration ability. The signal can travel up to 280 meters. Even if the team is spread out a little, tourists can still hear clearly.   More practical is the 008B two-way interactive guide device. Unlike traditional explanations where only the tour guide speaks and tourists listen, this one can achieve real-time interaction - if someone in the team asks a question, the tour guide answers, and everyone can hear it simultaneously, especially suitable for study tour groups to exchange knowledge and for enterprises to answer questions during inspections. Moreover, it supports multiple teams to use simultaneously, with a very small channel bandwidth, allowing each to speak independently without disturbing each other, and no longer having to endure the noise of multiple teams operating simultaneously.   2.Exclusive for VIP reception: Zone guidance system, intelligent and precise   If the scenic spot needs to receive VIP teams, leaders for inspection, or do high-end customized tours, the zone guidance system can make the experience more professional and more considerate. Yingmi's zone guidance system uses LD high-precision positioning technology, combined with three positioning methods of RFID, infrared, and WiFi, achieving the intelligent effect of "the explanation starts when the person arrives and stops when the person leaves; the explanation stops when leaving and starts when entering the next area". The guide leads the team into a certain area, the explanation starts automatically, leaves after leaving, automatically turns off, and when changing areas, the sound transitions naturally without interruption or loss of sound. It also has the function of audio-light linkage. Once the explanation is activated, the lights in the corresponding area will automatically turn on, and they will go off once the explanation is over. This not only creates a sense of ceremony but also guides tourists to focus on the current scenery. Additionally, the system can be connected to the background music and emergency broadcasting of the scenic area. In case of emergencies, it can promptly notify everyone, ensuring both the experience and safety. This is particularly suitable for high-end receptions.   3.Essential for independent travel: Self-guided interactive tour guide device, flexible and convenient   For tourists who prefer independent travel, the self-guided interactive tour guide device is definitely a great helper for in-depth exploration. Yingmi's self-guided device has two functions - automatic sensing and NFC touch. It can be used in any situation: in places where the distance between attractions is far, tourists don't need to move their hands, and when they approach the explanation point, the audio will automatically play; in places like folk custom exhibition halls in the scenic area, where the exhibits are densely placed and the space is small, just touch the touch tag of the guide device gently, and you can hear the corresponding explanation precisely, without any interference issues with the sensing.   There is also the M7C self-guided device, which uses the RFID-2.4G star distribution system design. The chest-worn style is very lightweight and convenient to wear for a whole day without any effort, and the battery life is also durable, sufficient to support an all-day tour. It can switch between 8 languages and has language prompt sounds. The next time it is powered on, it can automatically restore the language selected last time. Foreign tourists will also find it convenient to use. The guide device can store multiple explanations, whether it's the history of the scenic area, the legends of the attractions, or folk culture, geographical knowledge, all can be explained clearly, allowing independent travel tourists to control the pace themselves and hear what they want to hear wherever they go.   Ⅲ.Why choose Yingmi scenic area wireless guide device? These advantages are very practical   1.The technology is reliable, and the sound quality and stability are online   Yingmi's products use specialized digital filtering and noise reduction technology, which can filter out environmental noise, making the explanation sound purer; and the PMU safe intelligent lithium battery power management technology not only has a long battery life (the self-guided device can work for at least 10 hours, and the team explanation device can stand idle for over 11 hours), but also is explosion-proof, consumes less power, and is reliable for long-term use in the scenic area.   All devices undergo 5 strict tests and have passed international certifications such as EU CE and RoHS, as well as domestic CMA and CNAS tests. Even if the scenic area environment is complex, such as high temperatures, humidity, or many buildings blocking the view, the equipment can still operate stably and the signal will not be interrupted.   2.Suitable for various scenarios, can be used in scenic areas and exhibition halls   Yingmi's wireless guide device is not only suitable for natural scenic areas and historical sites, but also can be used in places like museums, folk custom exhibition halls, and science and technology museums in the scenic area. The product types are also diverse, including lightweight and compact, multi-functional, and high-end customized models. Whether it's large-scale team reception, high-end VIP services, or individual independent travel, there is a suitable style for each.   The company has an automated SMT production line, from research and development, production to sales, installation, and after-sales, it can control everything itself. It can also customize the guide plan according to the size, terrain, and reception requirements of the scenic area, making the equipment and scenic area scenarios perfectly match.   3.Has international certifications, quality and service are guaranteed   Yingmi is a national high-tech enterprise and big data enterprise. Its products have already been sold all over the world and have passed ISO9001, 4001, etc. three-body certifications. The quality has been recognized by many national customers. The company's service  with a 90-second response time before sales, and free sample testing can be provided,with 1000 real cases for reference；during the middle process,on-site investigation of the site can be carried out for urgent orders， and the goods can be dispatched on the same day; after-sales provides professional installation services and free technical support and lifetime guarantee,and there is no need to worry about the scenic area when using it.   FAQ   1. Can the wireless guide device's signal cover large scenic areas? Answer: No problem at all! The signal of the team guide device can travel up to 280 meters at its maximum range. The zone guide system and self-service navigation machines use multiple positioning technologies, ensuring no blind spots in signal coverage. Even in mountainous areas or scenic spots with many buildings, the signal remains stable.   2. Do the navigation machines support multiple languages? How many languages can they support at most? Answer: Yes! For example, the M7C model can switch between 8 languages. If more languages are needed, it can be customized in advance by communicating with the company. Foreign tourists can also use it with confidence.   3. How about the device's battery life? Can it meet the needs of all-day reception in the scenic area? Answer: Absolutely! The self-service navigation machine can work for at least 10 hours, and the team guide device has an idle time of over 11 hours. The 8-10-hour reception needs of the scenic area can be fully covered. Moreover, charging is very convenient, and it can charge multiple devices simultaneously.   4. After purchasing in foreign scenic areas, can installation and technical support be provided?

When foreign customers are preparing audio guide equipment for museums, they are often confused by a bunch of problems - interference occurs when multiple teams visit simultaneously, the audio guide in a minority language cannot keep up, tourists' ears get sore after wearing it for a long time, and even the equipment fails to pass the certification and gets stuck at customs clearance. In fact, when choosing a wireless audio guide for a museum, it's not just a matter of buying any device that can make sounds. It needs to precisely align with the key points of "no interference for multiple teams, coverage for multiple languages, comfortable wearing, and durable usage".   Ⅰ.How does Yingmi fit into museums? Technology and products are spot-on.   Yingmi's selection as the preferred option for international museum forums, Guizhou Provincial Museum, and China National Museum is based on its comprehensive solution to the museum's pain points. Whether it's anti-interference, multilingual support, or wearing experience, all have been specifically optimized. It's extremely user-friendly.   1. Anti-interference: No interference even when multiple teams are present   Yingmi has specially optimized anti-interference technology for museums. The team audio systems it offers all come equipped with 4GFSK signal modulation technology, combined with a 200k ultra-small channel bandwidth, which can open up 100 independent channels. In simple terms, even if 100 teams are visiting the museum simultaneously, they can each listen to their own content without any interference.   During an event at the International Museum Forum, several delegations from different countries visited simultaneously. They used Yingmi's equipment. Different delegations used different channels, and there was no interference throughout the process. The main speaker's explanation was clearly transmitted to everyone's ears, and the organizers later reported that "the stability was much better than expected".   2.Multilingual + high-definition sound quality, restoring the old stories of the exhibits   For multilingual needs, Yingmi has the HM8.0 multilingual sharing platform. It comes with 8 major language mainstream languages by default, and small languages can also be customized - whether it's the tone of Arabic, the ending sound of Thai, or the less common Hungarian or Polish, as long as you provide audio or text, the sound quality algorithm can be optimized to make the pronunciation extremely realistic.   More importantly, Yingmi has the SOC embedded integrated digital noise reduction technology, which can precisely filter out the crowd noise and air conditioning noise in the exhibition hall. Even if tourists are standing in a busy exhibition hall, they can still hear the historical background and artistic value of the exhibits, just like having a dedicated guide chatting beside them.   3.Comfortable wearing + long-lasting battery life, suitable for long museum visits   Yingmi truly understands the needs of museum visitors. Many of its devices have adopted Ergo ergonomic design. Take the K8 team audio system for example, it is a non-intrusive ear hook design, weighing only 22g, as light as not wearing it at all. Tourists can wear it for a long time without ear pain, and it also solves the hygiene problem of in-ear devices. The receiver has a battery life of 7-8 hours, which can fully withstand an all-day visit, and there's no need to find an external power source for charging in the middle.   Moreover, the equipment management is also convenient. It is paired with a professional metal contact charging box, allowing for batch charging that is safe and convenient. Museum staff don't have to spend a lot of time fussing with the equipment.   4.International compatibility + considerate after-sales service, foreign customers don't have to worry   Yingmi has thought of the details for foreign customers: All devices have passed EU CE and RoHS certifications, and have undergone dual testing in China's CMA and CNAS. They can smoothly clear customs in most countries around the world and can provide complete certification documents. The charging module supports a wide voltage range of 100V-240V. Whether it's 220V in Europe or 110V in America, you can plug it in and use it right away without needing to buy a converter.   The after-sales service is more considerate. There is a 9G full-cycle service - from pre-sale to post-sale. It can respond within 90 seconds and provide free sample testing; during the sale, it provides multilingual operation guidance to prevent you from not understanding; After-sales service can solve most problems remotely. If you need to have the equipment repaired, just send it back to the factory. Within 10 working days, it will be repaired and sent back to you. There is absolutely no need to worry about "being unable to find a person for after-sales service".   Ⅱ.How to choose between different-sized museums? The Yingmi model fits perfectly.   The needs of large comprehensive museums and small specialized museums are different. Random selection will only waste money. Based on the common scenarios of foreign customers, these models can precisely match:   1. Large comprehensive museums, multi-team reception: Choose the K8 team explanation system.   This is a reliable "all-in-one" solution for museums with multiple teams and high traffic. It supports one-to-many explanations, one transmitter can connect countless receivers, and it can automatically synchronize frequencies - the receiver automatically matches the transmitter channel after turning on, and tourists don't need to manually adjust, they can use it right away when picking it up.   Its communication range can exceed 100 meters, and the signal won't break even if tourists wander freely in the exhibition hall. The channels also have a memory function, the receiver will default to matching the last used channel when turned on, and there is no need for repeated debugging. The museums around Suzhou Taihu Scenic Area used this model before, and they received several groups of teams every day, without any problems such as crosstalk or signal interruption.   2.Small specialized museums, limited budget: Choose the QR code explanation system.   If the museum has a limited budget but wants to provide high-quality explanation services, the Yingmi QR code explanation system is perfect. No need to buy a bunch of receivers, tourists can simply scan the QR code on the exhibit to hear multilingual voice explanations, and they can also watch pictures and videos. The form is particularly rich.   The advantages of this system are clear at a glance: the label production cost is low and it is durable, the explanation content can be updated in real time; no installation or debugging is required, tourists can use their own mobile phones, which is convenient and hygienic. Small specialized museums can use it to enhance the sense of technology and save on equipment procurement and maintenance costs, with extremely high cost performance.   3.Temporary exhibitions, mobile explanations: Choose the E8 integrated explanation device.   If the museum is holding a temporary exhibition and needs mobile explanations, the E8 integrated explanation device is the first choice. It weighs only 16 grams, with an integrated design that is fashionable and high-end, and it is convenient to carry: it supports main and secondary dual explanations, two main speakers can alternate speaking, and it can also receive audio equipment to play pre-recorded explanations, which can reduce the burden on the main speakers.   Its anti-interference and noise reduction performance are not shabby. Even in a temporary exhibition venue, the explanation sound can be clearly transmitted, making it particularly suitable for short-term and high-frequency mobile explanation scenarios. Conclusion   For museums, wireless audio guides are not merely "optional supplementary equipment", but rather a crucial tool that can fully explain the cultural significance of exhibits and enhance the visitor experience. Yingmi has gained popularity among many museums worldwide due to its strong features such as anti-interference, multilingual capabilities, and comfortable wearing, along with models suitable for various-sized museums, international compatibility, and attentive after-sales service.   Whether you are dealing with large comprehensive museums, small specialized museums, or organizing temporary exhibitions, Yingmi has corresponding solutions. There is no need to worry about "which one to choose"; simply pick based on your specific situation and needs, and every visitor will be able to hear the story of the exhibits clearly.   FAQ   Q1: How many minor languages can be customized? Can the sound quality be guaranteed? A1: Any number of minor languages can be added. The default is 8 for mainstream languages, and for minor languages, they can be customized as long as you provide audio or text. The sound quality will be optimized through algorithms to restore the pronunciation details of the language, making it clear and natural to listen to.   Q2: Are all the necessary certifications for equipment clearance complete? A2: Absolutely! All devices have passed EU CE and RoHS certifications, and have also undergone dual testing in China's CMA and CNAS. They can be cleared for export to most countries in the world without any issues. Complete certification documents can also be provided if needed.   Q3: The museum receives a large number of visitors every day. Are the devices prone to failure? How long is the warranty? A3: Not at all! Yingmi has a 7S product quality control system. Every device must undergo 5 strict inspections. It is very durable. The core components (chips, batteries, microphones) have a 2-year warranty, and the entire machine has a 1-year warranty. There is also a lifetime free repair service.   Q4: Does the QR code explanation system require the museum to maintain its own server? A4: No! Yingmi provides cloud data hosting services. The server uses gigabit-level fiber optic and dual-line access, and has a hardware firewall. The museum only needs to update the explanations. The subsequent server maintenance is all handled by Yingmi, which is convenient and saves effort. About us   HEFEI HUMANTEK.

When foreign customers purchase multi-to-one wireless audio guide devices, many of them tend to focus on the price - only to find out later that when multiple teams use it together, there will be interference, the sound becomes indistinct in noisy environments, it cannot last the entire day for a meeting, and it may not work due to voltage incompatibility. In fact, the core of a multi-to-one audio guide device is "stable sound transmission and suitable for the scenario". Choosing the right product is much more reliable than being tempted by low prices.   Having been in the audio guide device industry for 18 years, I have seen too many foreign customers get frustrated because they chose the wrong multi-to-one equipment. Today, let's take Yingmi audio guide devices, which have been exported globally for many years, as an example to discuss: What key points should foreign customers pay attention to when choosing a multi-to-one wireless audio guide device? How should they select models for different scenarios?   Ⅰ.The most annoying problem for multi-to-one audio guide devices in the foreign market   The multi-to-one mode seems simple - one main speaker and a group of listeners. But it really tests the strength of the equipment. The pain points reported by foreign customers are basically these four: If the equipment has poor anti-interference ability, when multiple teams use it together, the audience of Team A can hear the explanation of Team B, and the main speaker says one thing, the noise comes out one sentence, communication is directly disrupted. This is the problem that foreign customers often joke about, and it is the primary criterion for judging the quality of the equipment.   1.In noisy environments, the sound is unclear, and it's a waste of money and a nuisance   In factories, there are mechanical noises, at outdoor exhibitions, there are people shouting, and in large venues, there are echoes. In these scenarios, the sound of ordinary audio guide devices is directly covered over. The main speaker shouts, but the audience cannot hear the key information clearly. Buying the equipment actually reduces communication efficiency.   2.The battery life cannot last the entire day, and charging midway is extremely troublesome   International conferences and exhibitions usually last for a whole day, and sometimes even several days. If the audio guide device has a battery life of only 4-5 hours, it has to stop to find a power source for charging halfway. This not only delays the progress but also makes the reception experience greatly compromised.   3.International compatibility is troublesome, and voltage and languages are limited   Foreign customers are most worried about "getting the device but not being able to use it" - either the voltage is not compatible, and an adapter has to be bought separately; or it does not support small languages, unable to meet the needs of multi-national audiences; or even it has not passed international certification, and customs clearance becomes a problem. In the end, the equipment is piled up in the warehouse and wasted.   Ⅱ.Yingmi multi-to-one audio guide device: Solving scene problems in a practical way   Yingmi's ability to export globally for many years is based on its successful implementation of "stability and adaptability" in multi-to-one audio guide devices. Whether it is anti-interference, sound quality, or battery life, it precisely meets the needs of foreign customers. This is achieved through solid technical accumulation.   1. Anti-interference real skills: No interference even when multiple teams use it together   Yingmi's multi-to-one audio guide devices are all equipped with 4GFSK signal modulation technology and 200k ultra-small channel bandwidth, which can open up 100 independent channels. In simple terms, even if 100 teams are using it simultaneously in the same area, they can each listen to their own, and there will be no interference.   2.Noise reduction + high definition: Even in noisy environments, it can be heard clearly   For noisy environments, Yingmi has its own unique skills - SOC embedded integrated digital noise reduction technology, which can precisely filter out external noise and only leave the voice of the main speaker. Coupled with AI lossless original sound processing, even in noisy factories or crowded exhibitions, the audience can clearly hear every detail.   For example, at large mechanical industry exhibitions, the Yingmi 008A audio guide device performed particularly well. In the venue with dozens of mechanical equipment rotating simultaneously and multiple booths presenting technologies, this device relied on its strong noise reduction and high-definition sound quality to allow customers to clearly hear every technical parameter. The exhibitors said, "The communication efficiency is twice as high as that of the equipment used before."   3.Long battery life is convenient: No need to charge midway for the entire day   Yingmi has a brilliant solution for battery management - the PMU Secure Intelligent Lithium Battery Power Management Technology, which offers a much longer battery life than the industry average. Different models can meet the daily needs: The E8 transmitter can last for over 15 hours, and the receiver can last for 8 hours without any problem; The 008A and 008B transmitters and receivers can both last for 12 hours, which is sufficient for a 3-day exhibition.   What's more considerate is that the equipment supports fast charging. Even if you forget to charge occasionally, a short charge can meet your needs for half a day, and there's no need to panic about power loss in the middle.   4.International Compatibility is All Covered: Voltage, Language, and Certification are Stress-Free   Yingmi has already thought about the compatibility issue for foreign customers: The charging modules of all one-to-many presentation devices support a wide voltage range of 100V-240V. Whether it's 220V in Europe or 110V in America, you can plug it in and use it right away. It is equipped with the HM8.0 multilingual sharing platform, which has 8 mainstream languages by default and can be customized for smaller languages as needed. It can meet the needs of multi-national audiences.   More importantly, all devices have passed the EU CE and RoHS certifications, and have undergone dual inspections by China's CMA and CNAS. They can smoothly clear customs in most countries around the world, without the need to worry about certification issues.   III. How to Choose for Different Scenarios? Yingmi Models Fit Precisely   The requirements for one-to-many presentation devices vary in different scenarios. Random selection will only waste money. Based on the common scenarios of foreign customers, these models can precisely fit:   1. High-end international conferences, VIP receptions: Choose the E8 all-in-one presentation device   This is Yingmi's star model. It weighs only 16 grams and has an all-in-one design that is both fashionable and high-end, perfectly matching the tone of high-end conferences. It supports both main and secondary dual talks and audio playback, not only for one-to-many presentations, but also for multi-person collaborative presentations.   2.Factory visits, noisy exhibitions: Choose the 008A presentation device   If the scene is noisy and requires long-distance explanations, the 008A is the right choice. Its wireless amplification technology is particularly powerful, with a communication distance of up to 280 meters, excellent wall-penetrating effect, and even in large factories with different workshops, the signal will not be interrupted.   Moreover, this device is particularly durable, with good dust-proof and shock-resistant performance, suitable for complex environments such as factories and outdoor exhibitions, and doesn't require careful care.   3.Interactive training, seminars: Choose the 008B two-way presentation device   If one-to-many presentations require audience questions and interaction, the 008B is the best choice. It is currently the most advanced wireless two-way presentation device on the market, allowing the main speaker and audience to interact, with one-to-one questions and answers within the team, and everyone can hear clearly. It is particularly suitable for enterprise training, academic seminars, and other scenarios that require communication.   4.Daily receptions, long-term wearing: Choose the R8 ear-hanging presentation device   This device uses Ergo ergonomic non-in-the-ear design, and the audience won't feel pain in their ears even after wearing it for a whole day, and it also solves the hygiene problem. Its sound quality and stability are no worse than other models, suitable for daily museum tours, regular enterprise receptions, and other high-frequency usage scenarios, with extremely high cost-effectiveness.   IV. Yingmi's Additional Benefits: Not Only Good Products, But Also More Convenient Services   When foreign customers purchase equipment, they are not only concerned about the product itself but also the service. Yingmi's 9G full life cycle service is reassuring from pre-sale to post-sale:   Pre-sale: 90 seconds can respond, with 1,000+ real case references, and it also supports free sample testing - customers can test the device in their own scenarios first, and if satisfied, they can place an order immediately, with no risks; During the sale: On-site inspection can be provided for urgent orders, and they can be dispatched on the same day; After-sales: Professional technical support is available, even in foreign countries, most problems can be solved remotely, and the device can enjoy lifetime guarantee. More importantly, Yingmi has its own SMT assembly factory, where it controls the entire process from R&D to production. Each piece of equipment must pass five tests (high temperature, low temperature, vibration, sound quality, battery life), ensuring high quality. From the first unit to the 1 millionth unit, no safety incidents have occurred.   Conclusion   For foreign customers, a one-to-many wireless explainer is not just about being able to speak; the key lies in "stable sound transmission, suitable for the environment, and ease of use". Yingmi achieves this through its three core strengths: anti-interference, noise reduction, and long battery life. It also offers precise models tailored for different scenarios, along with comprehensive international compatibility and attentive services. As a result, it has become the preferred choice for many customers worldwide.   Whether you are preparing for a high-end international conference, factory visit, museum tour, or corporate training, Yingmi has a corresponding one-to-many solution. No longer need to worry about "which one to choose"; simply match it to the scenario and you can double the communication efficiency.   FAQ   Q1: For Yingmi's one-to-many speaker system, how many receivers can one transmitter connect to at most? A1: Generally, one transmitter can connect to no more than 100 receivers; if a larger number is needed, it can be customized by communicating with Yingmi in advance. The maximum number that can be accommodated is 500 receivers for synchronous reception.   Q2: Does the equipment support multiple languages? Can we customize the minor languages of our country? A2: Yes! By default, it supports 8 major languages such as English, French, and German. Minor languages can also be customized - as long as you provide the corresponding audio or text, Yingmi can optimize the sound quality algorithm and restore the pronunciation characteristics of the language, making it sound particularly natural.   Q3: Is the signal coverage of the equipment sufficient? Will there be blind spots when used in large venues? A3: The coverage range varies for different models. Model 008A can reach up to 280 meters, E8 and R8 can reach up to 120 meters. Most large venues are sufficient; if the venue structure is complex, Yingmi can also provide a signal enhancement plan to ensure that every corner can hear clearly. About us   HEFEI HUMANTEK.

Any tour guide who has led a group knows that the most exhausting part of leading a tour is not getting tired from walking but from shouting at the top of one's lungs without anyone being able to hear clearly. Especially in popular tourist attractions, with a large crowd, the sound from the loudspeaker is either drowned out by the noise or mixed with the voices of other tour groups, turning into an irritating noise. If tourists can't hear clearly, they will get upset. The guide's repeated explanations will also consume energy. The entire itinerary will be held back by the "explanation".   Fortunately, there is a solution now - wireless speakers. Not all wireless speakers are suitable for tour guides to lead tours. Choosing the right one can double the efficiency of leading a tour, while choosing the wrong one will only cause more problems. As an analyst with extensive experience in the industry, combining the actual feedback from many tour guides and the product advantages of the Yingmi brand, today I will explain how tour guides should choose wireless speakers for leading tours.   The problems of tour guiding are really time to be solved.   Problem 1: Crowded and noisy, even shouting loudly still "can't be heard clearly"   In popular tourist attractions, during peak seasons, every scenic spot is crowded with people. When the tour guide uses the traditional loudspeaker to explain, the tourists in the front think it's too noisy, while those in the back can't even hear a few scattered words. When it comes to narrow alleys or viewing platforms, the team disperses, and the tour guide has to stop and wait, repeating the explanation content over and over again. This not only wastes time but also disrupts the overall itinerary rhythm. Many tourists, because they can't hear the story behind the scenic spots clearly, can only take photos and check in, reducing the experience.   Problem 2: Multiple teams visiting simultaneously, the explanation sounds interfere with each other "disturbing the enjoyment"   This is a problem that both tour guides and tourists detest. Especially in closed or semi-closed scenarios such as museums and ancient city walls, several teams are visiting at the same time, and the explanations of different tour guides interweave together, turning into a "noisy soup". Tourists can't focus on listening to the explanation of their own team, and the tour guide has to deliberately raise the volume, leading to a vicious cycle where both parties' experiences are extremely poor.   Problem 3: One-way explanation lacks interaction, the tour atmosphere is "cold and quiet"   The traditional explanation mode is that the tour guide provides a one-way output. Tourists can only ask privately in a low voice or wait until the explanation is over to ask questions. This not only affects other tourists but also makes it difficult to answer their questions in a timely manner. Especially when leading study tour groups or corporate inspection groups, the demand for interaction is stronger. One-way explanation simply cannot meet the needs, and the visiting atmosphere of the entire team is rather dull.   Selecting the right wireless audio  guide device: These several models from Yingmi, precisely fit the tour guiding scenarios   Yingmi, as a brand deeply involved in the field of voice explanations, has long understood the core needs of tour guides. The multiple wireless speakers it has launched almost completely avoid all the shortcomings of traditional equipment. Whether it's a regular tour group, a study tour group, or a high-end VIP inspection group, there is an appropriate solution for each. For regular tours, the first choice is the K8 team explanation system. It adopts an ear-catching one-piece design, with the receiver weighing only 22 grams. Tourists wearing it on their ears for a whole day won't feel tired, and the non-intrusive design is more hygienic, avoiding the hygiene risks of sharing equipment among multiple people. The transmitter used by the tour guide weighs only 62 grams and hangs on the waist almost imperceptibly, much lighter than the old-fashioned equipment.   The most crucial point is its anti-interference ability. It uses the 860Mhz-870Mhz high-frequency band for transmission, which is far away from the interference of daily mobile phones and radio stations. Even if multiple teams are explaining at the same scenic spot, it can achieve "each explaining their own, not disturbing each other". The receiver doesn't need to manually change the channel, and the transmitter automatically locks and starts after unlocking, allowing the tourists to use it immediately. The tour guide doesn't need to spend time teaching, saving a lot of work.   The battery life is fully capable of meeting the needs of an all-day tour, and after charging, it can last for 7-8 hours. Even long-distance tours that start early and end late are sufficient. After the group is formed, it is also convenient to organize the equipment. The dedicated contact-type charging box has a metal casing, which is safe and free of fire hazards. It can charge multiple devices at once and can be directly stored, eliminating the need to find a separate place to store the equipment.   Strong interactive demand selection: 008B two-way interpreter. Essential for study tours and investigation groups.   If you bring a study tour or enterprise investigation group, tourists will have many questions to ask. Then the 008B two-way interactive interpreter is the most suitable. It breaks the traditional "guide speaks, tourists listen" one-way mode. The interpreter and tourists can have real-time interaction. Tourists can ask questions, the guide can answer, and everyone in the team can hear it simultaneously. There is no need for the guide to repeatedly answer the same question.   The signal transmission of this device is also very powerful. It adopts advanced wireless amplification technology, with excellent wall-penetrating effect. Even if the group is scattered in the scenic area, as long as they are within 280 meters, tourists can clearly hear the explanation. The channel also has a memory function, and the next time it is powered on, it will automatically match the previous channel. There is no need to re-frequency every time. The details of the design are particularly thoughtful.   Why is the Yingmi interpreter favored by tour guides?   Reliable technology, dual online sound quality and stability   Yingmi is a national-level high-tech enterprise, with a number of core patent technologies. All of its interpreters adopt SOC embedded integrated digital filtering and noise reduction technology, which can effectively filter the environmental noise in the scenic area, making the sound quality of the explanation purer, so that tourists can hear clearly and the guide doesn't have to shout. The equipment also applies PMU safe intelligent lithium battery power management technology, which not only has a long battery life but also has advantages such as explosion-proof and low power consumption. Even in a hot and humid scenic area environment, it can operate stably.   All equipment undergoes 5 strict tests and has passed international certifications such as EU CE and RoHS, as well as domestic CMA and CNAS dual standards tests. The quality is guaranteed.   Service is in place, solving the worries of tour guides   When a tour guide is leading a group outside, the most feared problem is that the equipment fails and no one is responsible. Yingmi's "9G full life cycle service" is very reassuring: pre-sales 90-second quick response, and it can also provide free sample testing, with 1000+ real cases for reference; during the sales process, it can conduct on-site site investigation, and urgent orders can be delivered on the same day, supporting multiple platform transactions; after-sales provides professional installation and free technical support. If there are quality issues after the sale, it can be exchanged without conditions within 3 months, and free warranty is provided within one year. Even if there are problems, they can be quickly resolved.   Model Target Scenarios Core Features Yingmi K8 Team Explanation System Regular tourist groups, scenic spot tours 860-870 MHz high-frequency band; automatic channel locking; contact charging box; SOC noise reduction technology Yingmi 008B Two-Way Interpreter Study tour groups, corporate inspection groups Two-way real-time interaction; advanced wireless amplification (wall-penetrating); channel memory function; SOC noise reduction technology Yingmi M7 Neck-Mounted Guide Device Foreign tourist groups, multilingual tours Multi-language explanation support; customizable audio storage; PMU safe lithium battery; ergonomic neck-mounted design   Compatible, meeting the needs of both domestic and international tour groups   Yingmi's products have been exported to dozens of countries around the world for many years and fully comply with international standards.
