Quality Tour Guide Audio System & Wireless Tour Guide System Factory

Whether it's for tourists in scenic spots or museums, or for staff conducting corporate receptions or exhibition explanations, if the operation process is too cumbersome, it will not only lower the user experience but also require additional training time, adding a lot of management burdens. Among many brands, Yingmi, which has been deeply involved in this industry for 18 years, has its 007B automatic sensing wireless guide device. With its extreme operational convenience, it has become the preferred model for customers. It solves all the operational problems in various scenarios through meticulous details.   Customers choose wireless guide devices: Ease of operation is the core necessity   Many customers have joked with me that they have bought products with seemingly impressive parameters but extremely complex operations before: tourists couldn't switch languages or trigger the explanation, and they simply didn't use it; staff had to spend a lot of time debugging the equipment and teaching tourists how to operate, adding a lot of extra troubles. Therefore, for customers, judging whether a wireless guide device is suitable is that the ease of operation is much more important than those unnecessary functions that are useless. And this is exactly the most prominent advantage of Yingmi 007B. Three core dimensions for judging the ease of operation of a wireless guide device   Based on years of industry experience and the actual usage feedback from customers, a simple wireless guide device only needs to meet three key points: First, there is no threshold for user operation, no need for training, and you can use it right away once you take it; second, the scene adaptation is flexible, and the automatic and manual modes can be switched easily; third, batch management is convenient, charging, storage, and maintenance do not require complex procedures. These three points, Yingmi 007B has done very well, precisely meeting the usage needs of customers.   Yingmi 007B: Making "Ease of Operation" Perfectly Ultimate, Suitable for All Scenarios   Since 2007, Yingmi has been dedicated to making wireless guide devices for 18 years.

Many brands boast about their impressive functions, but in reality, they all have flaws when it comes to usage - they are prone to breaking during bulk transportation; the operation is outrageously complicated, and it takes staff a long time to master it; some are not suitable for the scenarios and fail to meet compliance standards, causing frequent glitches during customs clearance. To determine whether a brand's product design is reasonable, the key lies in whether it can precisely address the actual problems of the customers. In this regard, Yingmi, which has been deeply involved in the industry for 18 years, undoubtedly has the most say. Its M7C automatic sensing + team presentation system has perfectly incorporated the word "reasonable design" into every detail.   The core standard for a reasonable wireless presentation device design is something that customers must keep in mind.   For customers, "reasonable design" is never just an empty slogan; it must be implemented in every use. This is also the key to judging a brand's design capabilities, especially suitable for common multi-scenario usage needs such as in scenic spots, museums, and corporate visits. Remember these points, and choosing a product won't lead to any mistakes.   1. Portability design: Must be compatible for bulk use and withstand long-distance transportation   When customers purchase presentation devices, they usually do so in bulk, either for large-scale reception in scenic spots and museums or for cross-border visits and exchanges in enterprises. This requires both single-device portability and the ability to withstand long-distance transportation and management - not only should each device be portable, but it should also be convenient for batch transportation and management. Many brands have overlooked this aspect, making the devices bulky and difficult to store, resulting in frequent bumps and damages during long-distance transportation, which adds extra costs for the customers. Such a design is definitely unreasonable. Truly reasonable portability design should not only make each device comfortable to wear and not press on the ears, but also consider the convenience of batch storage and long-distance transportation, so that customers don't have to worry about it.   2. Easy operation design: Compatible with multilingual users, and novices can quickly master it   The usage scenarios in foreign countries are quite special. Users may come from different countries, with different languages and operating habits. Therefore, a reasonably designed wireless audio guide device must be simple and understandable to operate, without the need for complex training. It should be ready to use as soon as it is brought over. Additionally, multilingual compatibility is a core requirement, which can help customers solve the problem of a shortage of interpreters for minority languages. This is also an important basis for customers to judge whether the design is reasonable. Devices with cumbersome operation steps and only supporting a single language are not in line with the actual needs of customers and are not practical.   3.Scene adaptability design: Suitable for multiple scenarios and durable   The presentation devices purchased by customers are rarely used in a single scenario; they usually need to be used in both indoor and outdoor environments - such as museums and exhibition halls indoors, scenic spots and squares outdoors, and even noisy enterprise production workshops. This requires the design of the device to be compatible with the usage needs of different scenarios, with stable signals and clear sound quality, and also durable enough to adapt to different environmental conditions. In addition, the battery life should not be sloppy, as it must be able to meet the needs of all-day use, avoiding frequent charging that would delay the reception efficiency. Otherwise, even the most functional design would affect the user experience.   Benchmark design: Yingmi M7C, a reasonable choice for multiple scenarios   The M7C automatic sensing + team presentation system from Yingmi is a wireless presentation device specifically designed for multiple scenarios, perfectly meeting the four standards of reasonable design mentioned above. Since its launch, it has been recognized by many customers and has become the preferred product for bulk purchases. Every design detail of it can show the precise control of customer needs. 1. Portable storage design: Comfortable to wear and convenient for batch transportation and management   The M7C adopts an integrated design of the body and the headphones, with a compact and lightweight structure. When worn on the body, it hardly causes any weight sensation. Even if worn for a long time, the ears won't feel any pain. It is particularly suitable for long-term reception in scenic spots and museums. In addition, it is equipped with a dedicated all-aluminum storage box. The outer frame is extremely sturdy, with silicone film square slots and top sponge. Each device can be perfectly inserted into the slots, reducing vibration and moisture during transportation, and effectively preventing equipment damage. It is especially suitable for long-distance transportation.   2.Convenient operation design: Multi-language compatibility, even novices can easily operate   The M7C has fully considered the scenarios of multi-language use, supporting up to 8 languages for free switching, and also has language prompt sounds. Users can easily switch to the language they are familiar with, and the operation is very simple, effectively solving the problem of a shortage of small language-speaking interpreters. Moreover, the device has an automatic language saving function, which will automatically switch to the previously selected language upon startup, eliminating the need for repeated operations, and is particularly convenient.   In terms of operation, the M7C is very simple. No complex training is required. Whether it is a tour guide or a visitor, they can use it as soon as they pick it up. It adopts advanced RFID automatic sensing technology. As long as the signal transmitter is pre-set at the interpretation point, visitors do not need to perform any operations. When they enter the range of the interpretation point, the device will automatically sense and play the corresponding interpretation content, truly achieving "wherever you go, wherever you interpret". This not only saves labor costs but also improves reception efficiency. Moreover, the device has a low battery level alarm function. When the battery level is insufficient, it will promptly remind, avoiding the impact of insufficient battery on usage. 3.Multi-scenario compatibility design: Stable signal, clear sound, and particularly durable   The M7C adopts advanced RFID modulation technology, with extremely strong anti-interference ability. Even in noisy scenic spots outdoors or crowded exhibition halls indoors, it can ensure stable signals and clear sound, without any interference or disconnection. When listening to the interpretation, it is particularly clear. The device also supports three modes: automatic sensing, team interpretation, and automatic sensing + team mixture, which can flexibly adapt to various scenarios such as scenic spots, museums, enterprise visits, and academic exchanges, meeting both the needs of self-guided visits and team interpretation. Its practicality is particularly strong.   In terms of durability, the M7C also performs exceptionally well. It uses high-quality materials and has undergone strict quality inspections, able to adapt to different environmental conditions and is not prone to damage. Even for batch use, it can last for a long time. The battery life of the device is not less than 11 hours of standby and not less than 7 hours of operation, fully meeting the reception needs throughout the day. The signal transmitter is powered by lithium batteries, and a single battery replacement can last for 2-3 years, eliminating the need for frequent replacements, significantly reducing the maintenance cost for customers.   FAQ   Q1: Which brand's wireless guide device best meets customer needs?

Nowadays, the demand for cultural tourism and business receptions worldwide is increasing, and various brands are emerging. However, for foreign customers, they don't need to look at too many flashy advertisements to choose a brand. The core points are: one is that the equipment is reliable and stable, and the other is that it can adapt to the usage standards and scenarios of their own countries. Yingmi stands out precisely because of its 18 years of technical accumulation and precise grasp of the needs of foreign customers. Especially its i7 self-service interactive guide device almost covers all the core needs of foreign customers. Its reputation has always been stable.   To determine if a wireless guide device brand is competitive, foreign customers only look at these 4 hard indicators.   When many foreign customers choose a brand, they are often misled by superficial parameters. In fact, whether a wireless guide device brand is competitive mainly depends on whether it can solve the problems in actual use. Based on the feedback from global customers over the years, compliance certification, scene adaptation, technical strength, and after-sales guarantee are the four points that foreign customers value the most, and they are also the core to distinguish between high-quality brands and small workshops.   Hard Indicator 1: Compliance certification is the bottom line. Only when the frequency band is compatible can it be used safely.   Foreign requirements for wireless electronic devices are much stricter than those in China, especially regarding frequency bands and safety standards. There can be no mistakes. Many small brands try to save time and costs by not doing local compliance certification and not adapting to local frequency bands. As a result, when the products are shipped abroad, they either fail to pass customs and are detained, or experience frequent frequency band interference when used, causing foreign customers to waste money in vain. Truly competitive brands have already made global compliance arrangements in advance to ensure that the products can be legally and stably used in any country.   Hard Indicator 2: Comprehensive scene adaptation is necessary for the brand to go far   The usage scenarios of wireless guide devices are very diverse, ranging from museums and historical sites to enterprise exhibition halls and outdoor scenic spots. Foreign customers do not want a device that can only be used in one place; instead, they want a solution that can meet the needs of multiple scenarios at once - such as self-service sensing in exhibition halls, no need for manual supervision; strong anti-interference in outdoor scenic spots, not afraid of wind and sun exposure; multi-language support in enterprise receptions, able to handle international customers. The more scenarios a brand can cover, the more it can impress foreign customers, and the stronger its market competitiveness will be.   Hard Indicator 3: Strong technology is necessary to ensure the usage experience   The clarity of sound quality, the stability of the signal, and the duration of battery life - these are the most intuitive usage experiences for customers, all relying on technology support. For example, in noisy scenic spots, can it filter out noise; when multiple teams use it simultaneously, will there be crosstalk; can it last a whole day when on tour or in an exhibition hall? These details are what foreign customers focus on. Those small brands without much technical accumulation often fail in these key areas, and once they use it, they have no repeat customers, unable to form long-term competitiveness.   Hard Indicator 4: Complete after-sales service is necessary to dispel cross-border concerns   For foreign customers, after-sales is really very important. If the equipment fails to work properly in the foreign country, can it be repaired in time; when encountering problems in operation, can someone be found to guide; after batch purchases, can customized services be provided? These all directly affect the customer's choice. Competent brands will build a global after-sales system to ensure that foreign customers don't have to worry about after-sales, buying with peace of mind and using with confidence. Yingmi i7: Mastering customer pain points, pulling full competitiveness with details   Yingmi's success in the global market is not through advertising, but through the actual performance of the i7 self-service interactive guide device. This device precisely understands all the pain points of foreign customers, and every detail design is in line with actual usage needs. It not only improves customer experience but also makes Yingmi's brand competitiveness stronger and stronger.   1. Full compliance + adjustable frequency band, no trouble in cross-border use   Foreign customers choose i7 because they are most assured of its compliance and frequency band compatibility. This device has passed the EU CE and RoHS certifications and also supports fine-tuning according to different national frequency standards. Whether it is shipped to Europe, America, or Southeast Asia, it can meet the local usage regulations without worrying about compliance issues. Moreover, it uses the Type-C fast charging interface, which is compatible with global voltages ranging from 110V to 220V, and there is no need to specially purchase conversion adapters. Any ordinary adapter can be used for charging, completely solving the voltage problem for cross-border use.     2.Automatic sensing + multilingual support, suitable for all scenarios   The most practical function of i7 is self-sensing - when combined with the sensing tag, when visitors approach the corresponding exhibit, the device will automatically trigger the explanation, and when they leave, it will automatically stop. There is no need for manual operation or following an on-site guide. This design is particularly suitable for museums, historical sites, and corporate exhibition halls, saving costs on human explanations and allowing visitors to visit at their own pace, providing a better immersive experience.   Most foreign customers have the need for multiple languages, and i7 supports customizing 8 mainstream language explanations. Whether it is receiving tourists from small language-speaking countries or holding international business exhibitions, it can easily handle them. Not only that, its anti-interference ability is also very strong. Even if multiple teams use it simultaneously in a small exhibition hall, there will be no frequency interference or noise issues. It is completely fine to use it in popular tourist attractions and large exhibition halls.   3.Hardcore technology support, convenient and durable to use   Sound quality and battery life are the core of the wireless explainer device. i7 has done a good job in both aspects. It is equipped with digital noise reduction technology, even in a noisy environment of 80 decibels or above, it can filter out the surrounding noise and transmit the explanation clearly to the visitors' ears, whether it is for elders or those with sensitive hearing, they can hear it clearly. The battery life is also reliable, with a single charge being able to last for 11 hours, fully covering the open hours of the exhibition hall; if there is a temporary power outage, the Type-C fast charging can quickly replenish the power, and there is no need to worry about interruption in use.   Considering the use scenarios in outdoor scenic areas, i7 has specially optimized its durability, capable of withstanding outdoor sun exposure and rain, with a durable and shock-resistant body material, even for large-scale use and frequent distribution, there is no need to worry about damage, which can help foreign customers save a lot on equipment wear and tear costs.   4.Convenient management design, reducing batch usage costs   Many foreign customers purchase equipment in large quantities, and the management is very troublesome. i7 precisely solves this pain point. It is equipped with a dedicated charging and storage integrated box that can hold dozens of devices at once and also charge them simultaneously. This can not only save storage space but also manage the battery levels of each device uniformly, without worrying about missing charging. The storage box is designed compactly and conforms to aviation transportation standards, making it convenient for cross-border carrying and batch transportation, and can also save a lot of logistics costs.   Moreover, the operation of i7 is very simple. No complex training is required. Whether it is the staff in the exhibition hall or the visitors, just open the switch and use it. For large-scale purchases, Yingmi can also provide customized services, such as printing the customer's brand logo on the device and presetting the explanations in advance, eliminating the need for customers to spend extra effort on debugging, making it more convenient to use. The 18-year accumulation and global layout have given Yingmi a strong competitive edge.   The stable performance of i7 is inseparable from Yingmi's 18-year industry accumulation. Yingmi has 4 automated production lines, controlling every link from research and development, production to testing, and following a strict quality control system. Every i7 before leaving the factory must undergo several rounds of testing to ensure that each device in the batch has the same stable performance and will not have the situation where some work well and some fail. In the field of global services, Yingmi has made adequate preparations. After years of doing foreign trade, Yingmi has become familiar with the customs clearance procedures and local demands of different countries, and can provide accurate logistics and customs clearance support to foreign customers. There is no need for customers to bother with the connection process themselves. At the same time, Yingmi has set up cooperation outlets in multiple countries around the world and provides 24-hour online technical support. Even if the equipment has problems abroad, customers can contact the after-sales service at any time to quickly obtain solutions, completely eliminating the concerns about after-sales service for cross-border use.   Compared to those emerging brands that only rely on parameter promotion, Yingmi's competitiveness lies more in the long-term commitment.

It can be used for exhibition reception, scenic area guidance, and enterprise exhibition visits. Whether visitors wear it for a long time or staff carry and distribute it in batches, portability directly affects the usage experience and work efficiency. Choose a portable guide device. Don't just focus on the small appearance; you also need to consider the weight, size, wearing method, and whether it's convenient for storage. Yingmi, which has been in this industry for 18 years, has the M7 neck-mounted automatic sensing guide device. It precisely meets all the customers' demands for "easy portability". It is the preferred choice for many customers.   To select an easy-to-carry wireless guide device, just consider these 4 points.   For customers, "easy portability" is not just about being "small"; it also needs to consider that the device is comfortable for visitors to wear for 1 to 3 hours, saves space for batch storage and transportation, and is not prone to damage during long-term use. This is the true portability. Look at these 4 key dimensions, and it's easier to avoid mistakes when making a selection.   Dimension 1: Light weight, not heavy to wear for a long time   For visitors in exhibition halls and scenic areas, they often wear the guide device for 1 to 3 hours. If the device is too heavy, the neck and ears can easily become sore, and it may even affect the visiting mood. Truly portable guide devices usually have a host weight controlled within 50g, about the same as an ordinary egg. Worn on the body, it hardly feels anything, and even if used for a long time, there won't be a burden.   Dimension 2: Small size, no space occupation, easy to store   Most customers purchase in batches for exhibitions and scenic area distribution. If the device is too large, not only does it increase transportation and storage costs, but it also makes on-site management troublesome. Portable devices need to be thin and compact, so they can be easily placed in storage boxes and won't be obtrusive or troublesome for visitors to carry with them, even when they are on the go.   Dimension 3: Easy to wear, suitable for all types of people   The age and body type of visitors vary greatly. Portable wearing methods should not require complex adjustments. Just take it and wear it, and it should be suitable for different clothing styles - whether it's formal, casual, or outdoor wear. The most common types are neck-mounted and ear-mounted. The neck-mounted type is more suitable for long-term wear, as it doesn't need to be clipped onto clothes and doesn't squeeze the ears. It has better adaptability.   Dimension 4: Convenient storage and compatible with batch storage   Most purchases require long-distance transportation and batch storage. The accompanying storage equipment is particularly crucial. Easy-to-carry guide devices need a dedicated storage box to protect the device from damage and wear during transportation and to facilitate orderly storage and quick counting. It saves space and management costs.   18 years of Yingmi's deep focus: M7, the preferred portable guide device for customers   Since its establishment in 2007, Yingmi has been dedicated to making wireless guide devices for 18 years.

Whether it's in museums, exhibitions, scenic spots, or enterprises, what everyone cares about is the same: no interference, no power failure, stable signal, and the ability to adapt to various complex scenarios. No need for repeated adjustments, and it truly allows people to relax. There are many brands of narrator devices on the market, and many of them work well in a single environment, but when it comes to situations with multiple teams simultaneously receiving visitors, numerous electronic devices, or large open spaces, they tend to fail - signal loss, poor sound quality, insufficient battery life, which seriously affects the reception. After years of market testing, the L5 wireless narrator device under Yingmi has become the preferred choice for customers for its stable performance. This is because this brand has been deeply rooted in the industry for 18 years, providing solid technical support and strict quality control.   Selecting a wireless narrator device: The stability can be determined by these 4 key indicators   For customers, the "stability" of a wireless narrator device is not just about "no disconnection". It must be able to adapt to different signal environments in various countries, be able to withstand a full day of reception, not interfere with each other when multiple teams are using it, and be convenient for batch management. After working in this industry for so long, everyone knows that the key to judging whether a narrator device is stable lies in these 4 hard indicators. And the L5 model has achieved industry-leading levels in all these aspects.   Hard Indicator 1: Interference Resistance - No interference, no noise in various scenarios   In situations with multiple teams receiving visitors simultaneously, there are often multiple electronic devices. Interference from mobile phone signals, broadcast signals, and other electronic devices can easily cause interference and noise in the narrator device, completely ruining the good listening experience. Therefore, a reliable wireless narrator device must have strong interference resistance to be able to handle such complex scenarios.   Hard Indicator 2: Battery Life - No power failure during the entire reception period, convenient batch charging   In museums, scenic spots, and exhibitions, the reception time is usually 8 to 10 hours, and some large events even last for several consecutive days. If the narrator device runs out of power halfway, the reception will be interrupted, which is not only troublesome but also affects the reputation. In addition, most customers need to manage the equipment in batches, so whether it is convenient for batch charging has also become an important factor affecting stability.   Hard Indicator 3: Signal Transmission - Full coverage in open or complex environments, no blind spots   Scenic spots are usually more open, while museums and exhibitions are either multi-level exhibition halls or large areas. How far the narrator device can transmit signals and whether it can cover the entire area directly determines its stability. A good narrator device not only needs to be able to transmit signals stably over long distances but also needs to avoid signal weakening when passing through walls or being obstructed.   Hard Indicator 4: Quality Control and Adaptability - Meets standards, no malfunctions during long-term use   When customers purchase narrator devices, they usually need to use them in batches for a long time, so the quality control of the equipment must be perfect, and it cannot frequently malfunction. Moreover, the signal frequency standards of different countries are different, and the narrator device must be able to adapt to the local frequency and pass relevant international certifications to be able to use stably for a long time.   18 years of industry accumulation: Yingmi's technical strength supports the stability of L5   For a device to be stable, it cannot be achieved without the long-term investment and deep focus of the brand. Yingmi has been dedicated to the field of narrator display since its establishment in 2007 and has been fully involved in the entire chain of research, production, and sales of narrator devices for 18 years. It has 4 automated SMT production lines, from the core chips to the final assembly, all are controlled by itself. Unlike some brands that rely on outsourcing production, the quality control is fundamentally unsecured and prone to problems.   As a national-level high-tech enterprise, Yingmi has many core patent technologies and has already started foreign trade business. It has passed EU CE and RoHS international certifications and is familiar with the signal frequency standards of different countries. If overseas customers have any requirements, they can also assist in fine-tuning the equipment frequency to ensure stable operation in the local area. Over the past 18 years, Yingmi has served more than 4,000 customers and its products have been sold to dozens of countries. They have undergone various practical tests in overseas scenarios. Moreover, it has a strict 7S quality control system. Every L5 audio guide device must pass five tests to ensure zero accidents with 1 to 100,000 devices. L5 Wireless Audio Guide Device: Meets all requirements in all aspects, suitable for various overseas scenarios   Yingmi's L5 wireless audio guide device is a core model specifically developed based on customer needs, combined with 18 years of technical accumulation. It can precisely meet the stability requirements for various overseas reception scenarios, such as museums, scenic spots, exhibitions, and enterprise visits. The four hard indicators mentioned earlier - anti-interference, battery life, signal transmission, and quality compatibility - are all outstanding.   Anti-interference at its peak: Multiple teams working simultaneously, no interference, no noise   L5 adopts a UHF 794-806 MHz high-frequency band design and is equipped with special circuit processing technology, significantly improving its anti-interference ability and sound quality fidelity. Interference from external electronic devices such as mobile phones and broadcasts can be largely blocked. Moreover, it innovatively uses a reliable zero-delay radio receiving front-end, combined with digital audio processing back-end technology, ensuring no delay in signal reception. Even if several teams are explaining simultaneously in the same area, they can operate independently through multiple channels, each team using their own exclusive channel without interference or noise, perfectly solving the pain points of parallel reception by multiple teams overseas.   Battery life worry-free: No power outage throughout the day, batch charging is more convenient   L5 is equipped with high-performance polymer lithium batteries and uses PMU safe intelligent power management technology, which is both safe and environmentally friendly, and has excellent battery life. Once the transmitter is charged, it can operate for more than 30 hours, and the receiver can operate for more than 35 hours, fully meeting the 8 to 10-hour reception needs of the venue throughout the day, without frequent charging interruptions to the reception process. Signal stability: 150-meter coverage, no dead spots in any venue   The signal transmission distance of L5 can reach 150 meters. Whether it is an open scenic spot square, or multi-story museums or enterprise workshops, the signal can be fully covered, without the problem of audio loss or deterioration when visitors move a little further. Moreover, it uses digital audio lossless transmission technology, even with walls or obstacles, the sound quality can be maintained clearly, ensuring that the explanation content can be accurately delivered to the visitors' ears.   Another very practical design is that L5 has channel memory function. When the receiver is turned on, it will automatically match the channel it was on when it was turned off last time, without the need for repeated manual adjustment, reducing the faults caused by operational errors and making it more stable and convenient to use. The transmitter also has a full-function LCD display, showing all information at a glance, and the operation is very simple. Employees do not need special training and can use it right away.   FAQ   Q1: Can the L5 wireless guide device work properly in overseas markets and adapt to the local signal environment? A1: Absolutely. Yingmi has been operating in overseas markets for many years and is well-versed in the signal frequency standards of different countries. The L5 model can adjust the device frequency based on the country where the customer is located to avoid signal conflicts.   Q2: Can the L5 have enough battery life to handle 8-10 hours of reception in a venue? A2: There is no problem at all. The transmitter of the L5 can operate continuously for over 30 hours, and the receiver can operate continuously for over 35 hours. This is much longer than the reception time of an overseas venue in a day.   Q3: Will there be interference or noise when multiple teams use the L5 simultaneously? A3: Absolutely not. The L5 uses the UHF high-frequency band and special circuit processing technology. Its anti-interference ability is extremely strong, and it supports independent operation of multiple channels. There are 150 adjustable channels, and different teams can use their own exclusive channels.
