Quality Tour Guide Audio System & Wireless Tour Guide System Factory

Traditional self-guided audio devices are essentially "one-way broadcasting tools". Tourists can only passively listen and mechanically remember, with no sense of interaction at all. After a while, they become mere decorations and fail to effectively convey the cultural context of the scene or the value of the products. The core value of self-guided audio devices is not merely "being able to speak and broadcast", but more importantly, through innovative design, transforming tourists from "passive receivers" to "active participants". This has been the core direction of industry development in recent years. Yingmi, which has been deeply involved in the voice-guided display industry for 18 years, has, based on its extensive practical experience and technological accumulation, launched the M7 neck-worn automatic induction tour guide system. This system has broken the interactive deadlock of traditional self-guided audio devices through a series of targeted innovative designs, significantly enhancing the interactive experience and setting a benchmark for innovative interactive design in the industry. Many purchasing customers have given positive feedback after using it.   The Interactive Dilemma of Self-Guided Audio Devices Awaits Innovative Design to Break the Stalemate   For a long time, the self-guided audio device industry has been trapped in a misunderstanding - focusing only on basic functions while neglecting the interactive experience of users. This is the key reason why many products are sold but not used, and why customers frequently make sarcastic remarks. Based on my years of observation, the interactive challenges of traditional self-guided audio devices mainly lie in three aspects, which many customers can deeply relate to.   Firstly, the one-way output is too severe, leaving no opportunity for tourists to participate. Traditional self-guided audio devices mostly provide fixed-point broadcasts. When tourists reach the corresponding position, the device automatically plays a segment of the commentary, and then falls silent. If they want to listen again, they have to return to the point and re-sense it. The entire process is the device broadcasting and tourists listening, with no space for active participation, resulting in a very rigid experience. Tourists lose patience after listening for a while.   Secondly, the operation is too cumbersome, with a high threshold for interaction. Some products, although aiming to add interactive functions, have overly complex designs. Switching languages, replaying, and adjusting volume all require pressing multiple buttons, with a cumbersome process. Especially for the elderly, children, and foreign tourists, they simply cannot remember how to operate and give up after a few attempts. The so-called interactive functions eventually become useless.   Finally, the adaptability is too poor, and the interactive scenarios are too limited. The interactive designs of traditional products are very monotonous and cannot adapt to the needs of different scenarios - in museums and art galleries where exhibits are dense, the induction is often inaccurate, and the interaction fails directly; in large scenic areas, the signal is unstable, and interaction is impossible; in enterprise exhibition halls with diverse needs, there are no corresponding interactive functions, making it difficult to truly serve different groups and scenarios. Innovative Design Takes Action, Solving the Interactive Challenges of Self-Guided Audio Devices   In fact, to enhance the interactivity of self-guided audio devices, simply adding a few fancy functions is not enough. The core lies in focusing on "user experience" and "scene requirements" and making all-round innovations - simplifying operations to make it easy for everyone to use, aligning with the visiting rhythm of tourists to enrich interaction forms, and considering the adaptability to different groups and scenarios. Yingmi, with 18 years of experience in this field, has witnessed every iteration of the industry and collected feedback from thousands of customers. The M7 neck-worn automatic induction tour guide system it launched precisely solves the interactive challenges of traditional products through three core innovative designs, making it very user-friendly.   Ⅰ.Induction Innovation: From "Passive Listening" to "Active Following", Aligning with the Visiting Rhythm for Interaction   The quality of the interactive experience depends on whether the device can keep up with the visiting rhythm of tourists rather than forcing tourists to adapt to the device. The induction design of traditional self-guided audio devices is too rough, either triggering false alarms frequently or playing intermittently, which greatly affects the mood. The induction innovation of the M7 has completely solved this pain point, and customers who have used it all praise its practicality. The M7 is equipped with advanced RFID modulation technology and wireless communication power control technology. The selection of optical chips took two years, and only high-quality wireless IC chips with long lifespan, low power consumption, and strong anti-interference capabilities were chosen. The sensing accuracy and stability are particularly good. Just place a signal transmitter at the explanation points, and tourists can wear the M7 neck-mounted receiver. When they reach the corresponding point, the explanation will be automatically triggered and played. Before moving to the next point, the current point's explanation will continue to loop. Tourists don't need to operate manually; if they want to learn more about a certain exhibit, they can just stay longer. They can repeatedly listen to the key points, truly achieving "sound starts when people arrive, sound stops when people leave, and key points can be looped", which is particularly in line with everyone's visiting habits.   Ⅱ.Functional Innovation: Multi-dimensional Empowerment, Balancing Practicality and Fun Interactivity   To create a good interactive experience, practical and rich functional support is indispensable. The M7 does this very well. Unlike some brands that pile up a bunch of fancy but useless functions, the M7 focuses on the core needs of procurement customers and tourists, innovating functions that are both practical and interesting, catering to different groups of people.   The first point is multi-language interaction, which can accommodate different groups of people. The M7 comes standard with 8 languages and can also add minority languages or local dialects as needed. Tourists from different countries and regions can choose the language they are familiar with to listen to the explanations. At the same explanation point, multiple people can listen to different languages simultaneously, perfectly solving the problem of difficulty in finding small language talents and insufficient interactivity in foreign-related receptions and special cultural explanations. Moreover, language switching is particularly simple, without complex settings. Even foreign tourists who are not familiar with the device can quickly get started with a little guidance and truly participate in the interaction.   The second point is digital storage and rapid updates, which can adapt to dynamic scenarios. Traditional products mostly use tape storage, which is prone to wear and distortion over time, and the explanation content cannot be updated in a timely manner. However, the M7 uses digital voice storage, completely solving this problem. It can store up to 9,999 segments of explanation content, meeting the needs of different scenarios such as museums, scenic spots, and enterprise exhibition halls. What's more convenient is that it supports USB communication, allowing the explanation content to be updated in real time and quickly. For example, when exhibits are changed at an exhibition, new scenic spots are added at a scenic spot, or training content is adjusted in an enterprise, there is no need to return the devices in batches to the factory. They can be updated directly via USB, ensuring that the interactive content always keeps up with the changes in the scene and avoiding content lag.   The third point is the lightweight form factor innovation, significantly lowering the interaction threshold. To encourage active participation in interaction, the device should be easy to wear and use, which is the most important consideration in the design of the M7. Traditional self-service explanation devices are mostly heavy and bulky, with complex operations, making it impossible for the elderly and children to use them throughout the visit. However, the M7 adopts a neck-mounted design, which is particularly lightweight - the receiver weighs only 50g and the transmitter 27g. Wearing it around the neck is almost imperceptible, and even if worn all day, it won't cause fatigue. Moreover, there is no need for manual operation throughout the process. The elderly and children only need to wear the device and walk to the corresponding explanation point to automatically hear the explanation. It is very easy to use, and people of all ages can participate in the interaction. Ⅲ.Experiential Innovation: Detail Polishing, Making Interaction More Warm   A truly good interactive experience is always hidden in the details. When designing the M7, every detail was carefully considered to make the interaction more warm and comfortable for users. For example, its neck-mounted design is ergonomic, comfortable to wear, and less likely to slip off, suitable for long visits. The explanation sound uses SOC embedded integrated digital noise reduction technology, effectively blocking environmental noise. Even in noisy places like scenic spots and exhibitions, the explanation can be heard clearly, and the interactive experience will not be affected. In addition, it also supports self-adjustment of volume. Whether it's the elderly with poor hearing or tourists who prefer to listen quietly, they can all adjust the volume to a level that is comfortable for them, which is particularly considerate.   FAQ   Q1: Will the inductive interaction of M7 cause false triggers in a densely populated exhibition hall, affecting the interaction experience? A1: Absolutely not. You can rest assured. M7 uses advanced RFID modulation technology and wireless communication power control technology. The selection of chips was tested for two years, and only high-quality wireless IC chips with strong anti-interference capabilities were chosen, effectively avoiding signal interference from adjacent explanation points.   Q2: Is the multi-language interaction of M7 complicated to operate? Is it suitable for foreign reception scenarios? A2: The operation is extremely simple and is completely suitable for foreign reception scenarios. M7 comes standard with 8 languages and can also add minority languages and special dialects. Language switching does not require complex settings. Tourists can quickly operate it with a little guidance.   Q3: Will wearing the M7 for a long time cause discomfort? A3: There is no discomfort at all. Even the elderly and children can use it easily. The receiver of M7 weighs only 50g and the transmitter 27g, making it very light. The neck-hanging design also conforms to ergonomics, and there is no pressure when worn around the neck. Even if worn for a whole day, there will be no feeling of fatigue.   Q4: Can the interactive functions of M7 be adapted to dynamic scenarios such as corporate training and exhibitions? A4: Absolutely no problem. I have come into contact with many customers in the fields of corporate training and exhibitions, and they are all using M7. It can store up to 9999 segments of explanation content and supports USB for quick content updates. Whether it's changing exhibits at an exhibition or adjusting content for corporate training, it can be done quickly, making it particularly suitable for such dynamic scenarios.   Q5: Yingmi has been deeply involved in the industry for 18 years. Is the after-sales service and technical support for M7 guaranteed? A5: The guarantee is particularly comprehensive. Before sale, free sample testing and on-site venue inspection are provided. During sale, on-site installation and operation training are available. After sale, there is free technical support and lifetime warranty.

Many wireless tour guide devices seem to have good performance, but they fail due to the operation issue - complicated buttons, complex pairing, and the need for specialized training to get started. Whether it adds burden to the tour guide or causes trouble for visitors and guests, they will eventually be abandoned. For wireless tour guide devices, simple operation has never been an "add-on", but a "must-have".   Wireless tour guide devices, the simpler the operation, the better they can meet the needs of all scenarios.   When many purchasers choose wireless tour guide devices, they often fall into the trap of thinking that "the higher the parameters, the better", but they ignore the most core use experience - operational convenience. The users of wireless tour guide devices are very diverse, including full-time tour guides, occasional enterprise administrators, people of all ages visiting or visiting, even the elderly and children. If the operation is too complex, it will not only increase the training cost, but also frequently cause operational errors, affecting the explanation effect.   For example, in scenic area scenarios, there are hundreds of batches of tourists every day, and the tour guide needs to quickly distribute equipment and complete pairing. If each device needs to be manually adjusted to the channel and connected, it not only wastes time, but also causes dissatisfaction among tourists; for example, in museum scenarios, most visitors visit spontaneously, many people will not perform complex operations after receiving the equipment, if they need to repeatedly consult staff, it will significantly reduce the visiting experience; in enterprise reception scenarios, if VIP visitors or leaders visit, equipment operation errors will seem very unprofessional, affecting the enterprise image.   It can be seen that, regardless of which scenario, the simplicity of the operation of the wireless tour guide directly determines the usage efficiency and experience. Among many brands, Yingmi, which has been deeply involved in the industry for 18 years, by accurately grasping the user's needs, has integrated "simple operation" into the product design. The E8 wireless tour guide device of Yingmi has become the benchmark product in the industry for its convenient operation. 3 core standards for judging the simplicity of operation of wireless tour guide devices Standard 1: Connect immediately upon startup, no need for manual pairing, saving time cost   The first prerequisite for simple operation is "no need to worry about pairing". Many wireless tour guide devices require manual adjustment of the transmitter and receiver to the same channel. When used in batches, each receiver needs to be debugged one by one, which is not only time-consuming and labor-intensive, but also prone to channel confusion and connection failure. High-quality wireless tour guide devices should achieve automatic search for signals and automatic pairing upon startup, without the need for manual intervention, and can be picked up and used immediately.   Standard 2: Simple buttons, intuitive operation, no need for specialized training   Button design is the key to affecting operational convenience. Too many buttons will make users have no idea where to start, and complex operation logic requires specialized training to master. This obviously does not meet the needs of the general user. Good wireless tour guide devices should follow "minimalist design", only retaining core buttons, and matching a clear display screen, so that users can understand each operation at a glance, whether it is for the tour guide or ordinary visitors, no need to learn to quickly get started.   Standard 3: Convenient batch operation, suitable for large-scale usage scenarios   For scenarios such as scenic areas, museums, and large enterprises that require batch use, the convenience of batch operation is particularly important. If charging requires plugging and unplugging each device one by one, and storage and transportation require separate storage, it not only increases the burden on the staff, but also easily causes equipment damage or loss. Therefore, when judging the simplicity of operation, it is also necessary to look at the convenience of batch charging and storage of the equipment, and whether it can significantly reduce management and operation costs.   After 18 years of deep involvement, Yingmi has engraved "simple operation" into the product genes. Unlike some brands in the industry that follow the trend and only focus on parameters, Yingmi has been dedicated to the field of wireless audio guides for a full 18 years since its establishment in 2007.

A good wireless tour guide device is not about cramming in parameters or resorting to flashy features; its core lies in being well-designed and easy to use. Many devices on the market, despite boasting exaggerated performance parameters, are cumbersome to wear, have complex and difficult-to-master operations, suffer from charging issues, and are not suitable for specific scenarios. Truly good products always incorporate "reasonable design" into every detail, fitting the habits of ordinary users and adapting to the needs of different scenarios. Yingmi, with its 18-year expertise in the industry, has provided the most practical solution with its L7 wireless narrator device.   What are the core principles behind the "reasonable design" of wireless narrator devices?   Judging whether the design of a wireless narrator device is reasonable is not about how exquisite the appearance is or how magnificent the parameters are. The core lies in two points: "people" and "scenarios". In essence, it is about making the device comfortable and convenient for the narrator and the listener, whether in scenic spots, museums, or corporate receptions, and being able to adapt smoothly while also balancing convenience and practicality. This is the essence of reasonable design. Design that is not based on scenarios is useless even if it is top-notch; design that ignores user experience is difficult to implement even if it is visually appealing. This is also Yingmi's design philosophy over the past 18 years.   Core logic 1: Wearing design, prioritize "comfort and convenience"   The core users of wireless narrator devices are either long-term wearers of the transmitter by narrators or long-term wearers of the receiver by listeners. The comfort of wearing is directly related to the product's reputation. Devices with unreasonable designs are either cumbersome, pressuring the ears, or prone to falling off, even if they have strong performance, will eventually be eliminated by the market. A reasonable wearing design must be lightweight, ergonomic, and balance comfort and convenience, without burdening the user.   Core logic 2: Operating design, adhere to "minimalism and simplicity"   The user group of wireless narrator devices is extremely diverse, including young narrators and elderly tourists or attendees. Therefore, the operating design must be extremely simple and easy to understand, without requiring time to learn before using it. Many brands, in pursuit of "multifunctionality", have designed a bunch of complicated buttons and complex operation procedures, which instead raises the usage threshold. This is a typical case of unreasonable design - the functions are divorced from the actual needs of users, no matter how diverse they are, they are of no use.   Core logic 3: Hardware compatibility, fit "scenarios and efficiency"   The usage scenarios of wireless narrator devices are numerous, including outdoor in scenic spots, indoor in museums, enterprises and factories, and large-scale exhibitions. Different scenarios have different requirements for the equipment: outdoor needs to be resistant to interference and capable of long-distance transmission; batch use requires convenient charging and easy storage and transportation; indoor needs to be compact and not take up space. Reasonable hardware design is precisely to accurately hit these scenario requirements, ensuring efficient operation while reducing management troubles. After 18 years of deep research, Yingmi has integrated "reasonable design" into the product DNA.   Since its establishment in 2007, Yingmi has been dedicated to the field of wireless narrator devices for exactly 18 years. Unlike those brands that follow the trend and enter the market only by competing on parameters, Yingmi always puts user needs first and has deeply explored various usage scenarios. Yingmi's 18 years of industry experience have been transformed into the confidence of product design. As a national-level high-tech enterprise, Yingmi has four automated SMT production lines, covering the entire process of research and development, production, sales, and after-sales service. It understands better than any other brand the actual needs of users for "reasonable design" in different scenarios - no unnecessary design, only useful and easy-to-use design. This is also the key reason why Yingmi's products have long been recognized by the market.   Over the past 18 years, Yingmi has served thousands of scenic spots, museums, and enterprises, and has exported to dozens of countries, accumulating a vast number of actual usage cases. It is precisely because of these cases that Yingmi has become more aware that what users truly need are not those "high-end" parameters, but reasonable designs that are tailored to their needs and easy to use. And the Yingmi L7 wireless explainer is the epitome of this design philosophy. No matter what the scenario is, it can be precisely adapted, and every detail can show the "reasonable design" with care.   Yingmi L7: Implementing reasonable design in every detail   The Yingmi L7 wireless explainer is specifically designed for multiple scenarios for batch use.

Many emerging brands rush to launch new products to seize the market, often neglecting the core aspect of stability. However, Yingmi has been focusing on the field of voice explanation and display since its establishment in 2007. Over the past 18 years, it has formed a complete chain of services from research and development, production, sales, installation, and after-sales. It has served thousands of customers, covering various fields such as scenic spots, museums, government units, and large enterprises. It has also obtained multiple international certifications such as EU CE and RoHS. Its products are exported to multiple countries and regions around the world. The stability of its products has been tested in the long-term market, making it a reliable benchmark brand in the industry.   The stability of a wireless audio guide device mainly depends on four key dimensions:   When many customers are selecting, they often fall into the misconception that "the higher the parameters, the better". In fact, the stability of a wireless audio guide device mainly depends on these four key dimensions. Missing any one of them is not acceptable. These four dimensions directly determine the performance of the device in actual use and are the key to distinguishing between high-quality products and ordinary ones. This is also the core reason why Yingmi M7 can stand out.   Dimension One: Signal Transmission Stability, Say Goodbye to Disconnection and Crosstalk   Signal transmission is the foundation of a wireless audio guide device. How stable the signal is can be seen at a glance. In indoor exhibition halls with many walls and complex obstructions, and outdoor scenic spots with open areas and multiple teams operating simultaneously, if the signal is unstable, problems such as disconnection, crosstalk, and delay will come knocking. The experience of explanation will be instantly compromised. Common industry pain points include that some low-priced products use simple wireless technology, with short transmission distances and weak anti-interference capabilities. When multiple teams use it, crosstalk is severe, and frequent disconnections occur in areas with many walls, seriously affecting usage.   To determine whether the signal transmission is stable, three key points need to be considered: transmission technology, channel bandwidth, and anti-interference design. High-quality wireless audio guide devices will adopt advanced modulation technologies and reasonable channel planning, which can avoid external signal interference from mobile phones, radios, etc., and achieve stable transmission over long distances, adapting to different scenarios' needs.   Dimension Two: Battery Stability, Supporting Long-Term Use   Battery capacity directly determines the scenarios where a wireless audio guide device can be used. Scenic spots and museums receive a large number of visitors every day, so the equipment needs to operate continuously from morning to night; enterprises' receptions and large exhibitions may have continuous explanations lasting for several hours or even several days. If the battery capacity is insufficient, frequent charging will not only delay efficiency but also cause interruptions in the explanation, causing trouble for both customers and organizers.   Battery stability is not only about battery capacity, but also about power management technology. High-quality products will adopt efficient power management solutions, which can ensure battery duration and reduce power consumption, avoiding "phantom power" issues. At the same time, they will be equipped with convenient charging devices that support simultaneous charging of multiple devices, making it more convenient to use.   Dimension Three: Environmental Adaptability Stability, Dealing with Complex Usage Scenarios   The usage scenarios of wireless audio guide devices are particularly diverse. There are indoor exhibition halls with constant temperature and humidity, as well as outdoor scenic spots with high temperatures, rain, and dust; there are indoor exhibition halls with narrow spaces and dense exhibits, and outdoor squares with open areas. Poor environmental adaptability of the product is prone to failure in extreme temperatures, humidity, and dusty environments, which not only affects the service life but also lowers the usage experience.   Whether the environmental adaptability is stable mainly depends on the device's material, sealing design, and hardware protection capabilities.

There are many brands on the market, but Yingmi, which has been deeply engaged in the wireless tour guide field for 18 years, has become a hard brand for durability in the industry through solid R&D accumulation and strict quality control. Its classic model, the E8 wireless tour guide, has embedded "durability" into every design, catering to various usage scenarios of customers. It has been verified by thousands of projects worldwide and truly carries the banner of "long-term usability".   When choosing a durable wireless tour guide, these four core dimensions must be closely watched   Many customers think that "durability" means being able to withstand drops, but this is not the case. The durability of a wireless tour guide is a comprehensive matter. It depends on the material wear and tear over the long term, the stability of performance, the ability to adapt to different environments, and whether the battery life is sufficient. These four dimensions directly determine how long the device can be used and whether it will cause trouble. They are also the key points I repeatedly emphasize when helping customers select models.   Material and Craftsmanship: The Foundation for Withstanding Daily Wear and Tear   Wireless tour guides are frequently handled and moved around. During the process of tourists picking them up and putting them away, bumps and scratches are common. If the material and craftsmanship are not up to par, problems such as cracked shells, unresponsive buttons, and loose interfaces will occur within a few months, which is even more costly. Especially in places with high foot traffic and high reuse rates like museums and scenic spots, the equipment must be made of anti-drop and anti-wear materials and be assembled with precision to withstand daily wear and tear.   Stable Battery Life: The Key to All-Day Operation without Interruption   Most customers operate their devices throughout the day. If the device runs out of power in the middle of the day or charges inconsistently or incompletely, it will directly disrupt the service. A durable wireless tour guide not only needs to be equipped with a good battery but also have reliable intelligent power management technology. This ensures it can last the entire day and avoid overcharging, which can damage the battery. This way, the battery lasts longer and there is no need to frequently replace the device.   Interference Resistance: The Confidence to Perform in Complex Environments   Large exhibitions, museums, and factory areas have very complex signals. Mobile phone signals and radio frequencies can easily interfere with tour guides. Devices with poor interference resistance may experience cross-talk or disconnections, making it difficult for tourists to hear clearly and directly affecting the reputation. Therefore, durable devices must have mature interference resistance technology to ensure stable signals even when multiple teams are using them simultaneously, without causing any disruptions.   Environmental Adaptability: Adapting to Global Climates is Essential   Customers operate their businesses in various locations, some with high temperatures and intense sunlight, and others with high humidity and frequent rain. If the equipment cannot withstand these climates, it is prone to malfunctions. In addition, the protection during batch charging and storage should not be ignored. Only by paying attention to these details can the overall durability of the equipment be truly enhanced and unnecessary damage be avoided. Durability is not just a slogan; it is a comprehensive quality control process   Many brands in the industry only focus on short-term planning, making a quick profit and then leaving. They do not attach importance to R&D for durability. However, Yingmi is different. Since its establishment in 2007, it has been dedicated to the wireless tour guide field for 18 years, treating "durability" as its core. From R&D to production, every step is closely monitored to truly lay a solid foundation for durability. As a national high-tech enterprise and a big data enterprise, Yingmi holds multiple core patents and has set up four automated SMT production lines to achieve independent production of PCBA, ensuring quality control from the source and avoiding the problem of inconsistent quality control from external subcontractors.   In terms of quality control, Yingmi implements a 7S quality control system. Each device must pass five inspection stages. If any of the aspects such as material wear resistance, battery life stability, interference resistance, and environmental adaptability do not meet the standards, it cannot be released. This ensures compliance with global mainstream standards. All Yingmi products have passed the EU CE and RoHS certifications, meeting international environmental and technical requirements. Customers can use them directly without the need for additional complex procedures. For so many years, it has been used by over 4,000 customers in dozens of countries around the world.

It is both durable and user-friendly, and has achieved a remarkable record of zero accidents from 1 to 100,000 units, which is quite rare in the industry.   Material and craftsmanship: Lightweight and durable, balancing comfort and durability   Yingmi E8 adopts an integrated design. The transmitter weighs only 68.8g, and the receiver is even lighter, at only 18g. The lightweight design reduces the chances of bumps and drops during carrying and circulation by visitors - after all, the heavier the device, the higher the probability of accidental drops and the greater the damage. The receiver uses an Ergo ergonomic non-in-ear design, which not only does not press on the ears after long-term wearing and is comfortable, but also solves the hygiene problem of frequent wearing and reduces the risk of ear hook wear. The outer shell is made of high-quality wear-resistant material, and combined with precise assembly technology, it can resist water and dust. Daily friction and minor drops can be withstood, and the outer shell is less likely to break and the buttons are less likely to malfunction even after long-term and large-scale use. It is particularly suitable for high-frequency reuse scenarios.

It is both energy-efficient and long-lasting - the transmitter can work continuously for more than 15 hours, and the receiver can last for 8 hours. A single full charge is sufficient to last from opening to closing of the museum without the need for frequent charging to disrupt services. The accompanying HM-EB36/HM-EB48 contact charging box can charge 36 or 48 devices simultaneously. It not only charges quickly and safely, but also protects the battery, avoiding battery aging caused by ordinary charging and extending battery life. Additionally, the optional HM-50S all-aluminum storage box has silicone grooves and sponge inside, which can reduce vibration damage during storage and transportation, further enhancing durability and facilitating batch management.   Anti-interference: Multiple technologies, reliable and stable signal   Yingmi E8 uses 2.4GHz high-frequency band transmission, combined with 4GFSK signal modulation technology, and has SOC embedded digital noise reduction and filtering functions. In simple terms, it can effectively block interference from external signals such as mobile phones and radios. With a channel bandwidth of 200k, it can support 200 independent channels.
