Whether it’s international scenic spots receiving travelers, museums holding immersive exhibits, business exhibition halls hosting VIP clients, or universities carrying out academic exchanges, people’s demands for interpretation solutions have changed significantly—it can no longer be the old model of “one tour guide leading a group of people,” but should be flexible, smart, and able to handle the challenges in different situations. YINGMI has been engaged in the production of interpretation devices for 18 years and is well aware of these pain points. Therefore, it has introduced the M7C automatic sensing plus team interpretation system, integrating practical features such as automatic sensing, manual interpretation, and multi-language switching. It has created special solutions for different scenarios and has become the preferred choice for many international customers.


Yingmi is a national high-tech enterprise. The M7C can be used so efficiently thanks to its advanced RFID modulation technology, which has an especially strong anti-interference ability and can sustain both “automated sensing” and “team description” modes simultaneously. No matter what kind of facility situation it is, the Yingmi M7C team description system can execute stably, which has also been recognized by more and more international customers.
Scenic area tour guide: multiple teams don’t have adjacent sounds, and international visitors can understand
There are several challenges in international scenic areas: there are a lot of visitors, diverse team types, and many international visitors. Language barriers are common. If several groups shop together, the traditional audio guide is prone to crosstalk, and the experience is poor. In response to these problems, Yingmi M7C has developed a specialized solution.
Automatic sensing mode
As long as the scenic area installs RFID signal transmitters at scenic areas and viewing systems, visitors can walk over with the M7C tour guide device without pressing any buttons. The device will sound by itself—when they reach the ancient tree, it will automatically tell the history of the tree. Upon reaching the viewing system, it quickly presents the remote views and geographical experience, absolutely achieving the objective of “talking exactly where you go.” The most practical aspect of this mode is that visitors don’t need to rush along with the tour guide. They can stay anywhere they desire for as long as they want. Even the elderly and children can easily keep up and won’t fall behind.
Team tour function setting is very practical for receiving team visitors
The tour guide brings a transmitter. No matter how many people use the tour guide device, they can receive the signal. The transmitter uses a frequency of 860-870 MHz and can be tuned to 180 channels. When multiple groups visit together, each team has its own dedicated channel, so there won’t be any crosstalk. For example, Team A is discussing the ancient bridge and Team B is discussing the temple. Each side listens to its own material without any disturbance. The number of groups that the scenic area can receive in a day has increased compared to before.
The language challenge for international visitors has also been fixed
The M7C can be switched to 8 languages, including common ones such as English, French, German, and Japanese. If the scenic area has special needs, it can also add less common languages. What’s even more thoughtful is that it will remember the language you used last time. When you turn it on next time, you can straight switch to it without needing to adjust it constantly. The signal transmitter can be set with 9,999 numbers. Even if there are countless scenic areas in a large scenic area, each area can be given a dedicated description, ensuring no omissions.
The durability of the equipment is also suitable for use in scenic areas
The M7C tour guide can last for 11 hours on standby and can be used continuously for 7 hours without any problem. It is enough for visitors to explore for a whole day. The battery of the signal transmitter is even more carefree. It only needs to be replaced every 2 to 3 years, so there’s no need to bother with charging it every day. The accompanying storage box is made from aluminum alloy and has silicone grooves inside. It can hold 40 tour guide devices each time. Even if the scenic area needs to ship the equipment to the scenic areas on the mountain, there’s no need to worry about it getting damaged. It is very convenient to manage.
Museums and exhibition halls: listen silently to the descriptions
Museums and event halls put the best focus on quiet atmosphere. Moreover, the displays are heavily arranged and the descriptions are specialized. Conventional descriptions either make too much sound to interrupt others or are inaccurate in sensing and misinterpret the introductions of the displays. The Yingmi M7C focuses on both “quietness” and “accuracy,” and has developed a solution for social and museum scenarios.
The M7C tour guide device integrates the body and the headphones into one, making it particularly small and lightweight. It feels good when worn, and only when the headphones are on can the audio be heard. It won’t be played out and interrupt others, allowing the whole event hall to be peaceful. The RFID positioning technology it uses is particularly accurate. Even if 2 displays are close to each other, it can still identify them exactly, and there won’t be a situation where “you stand in front of display A and hear the description of display B.” This is extremely important in museums with a dense array of displays.
The M7C can also store a lot of informative material. It can hold 9,999 informative notes and supports formats such as MP3 and WMA. Whether it’s the historic tales of social antiques, the artistic ideas of artwork, or the curatorial concepts of special events, they can all be included. If a special event is held, the number of times a single description can be played can be limited, and regular displays can be listened to easily. The management is really flexible.
Don’t worry if you need to change displays temporarily. The team can upgrade the descriptions behind the scenes without needing to adjust each device one at a time. The signal transmitter can be adapted to 12 levels of signal strength, and the sensing range can be adjusted according to the dimension of the event hall to ensure that the description is triggered exactly. The accompanying contact-type charging box can charge 45 systems each time and can also be charged in a smart mode to protect battery life. If the ultraviolet sanitation function is selected, it will be even more hygienic for visitors to use. It is particularly suitable for crowded areas like museums.
It is also convenient for international museums to receive international visitors. The multi-language switching feature enables international visitors to understand the stories behind the social antiques without needing to find a translator. For example, when European visitors see Chinese social antiques, they can understand them by switching to English. The experience is much better than before.
Corporate exhibition hall and business function: professional and thoughtful, highlighting brand strength
For international businesses, product promotion and VIP customer reception services have an especially significant impact on their brand image. The equipment used before either made it difficult to hear clearly at the loud event site, or it would delay when several people were interacting to explain, and it was also prone to problems when VIP customers came. The Yingmi M7C has developed a professional and thoughtful solution for business scenarios.
In the corporate event hall, it is very convenient to use the automated sensing mode. Set up a signal transmitter beside the core product. When a customer walks over, the device automatically explains the technical specifications of the product, how to use it, and its benefits. Combined with physical presentations, the customer can understand it at the same time. If customers have any questions, the team can switch to the team description mode at any moment, get the transmitter to supplement the introduction of participation scenarios, customized solutions and other products. There is no need to change the equipment, and the connection is very smooth.
The signal at the event site was incredibly chaotic. Cell phone signals and amplification equipment from other booths might interfere with the descriptions. The M7C uses a specialized anti-interference technology, ensuring clear and secure audio even in a crowded event. With 180 flexible channels, multiple booths of the same company can use them simultaneously. For example, a booth selling refrigerators uses Channel 101, while one selling washing machines uses Channel 120. These channels don’t interfere with each other, dramatically improving the efficiency of customer service.
When receiving VIP customers, the details are especially thoughtful. The M7C can be customized with prompt sounds such as startup sounds and alarm sounds. Enterprises can add brand elements, for example, by playing a clip of the brand’s signature tune at startup, which will leave a deeper impression on customers. When the equipment is about to run out of power, it will remind the customer. The team can replace it for the customer in time and will not disconnect in the middle. If you are worried about losing your equipment, you can also select the anti-theft alarm and return reminder features. Even if there are many people at the event, you don’t need to worry about losing it.
The appearance of the equipment is also suitable for business events. The M7C tour guide is small, slim and light, and does not look out of place when worn. The transmitter is just 105x70x20mm (including the antenna). The tour guide can simply place it in their pocket and it will not affect the reception image. After the event, the charging boxes will be charged in pairs, and the storage boxes will be uniformly stored. There is no need to work overtime to arrange them, and the management team will also be relieved.
Institutional research and study: flexible adjustment, practical for both training and communication
International organizations arrange visits to their history museums, art events, and academic exchanges. The requirements for the equipment used for descriptions are really flexible—it needs to not only allow students to study independently, but also support instructors’ focused descriptions and facilitate international exchanges. The dual-style layout of the Yingmi M7C particularly meets these demands.
In school museums and institution history museums, the automated sensing mode is especially suitable for students’ independent learning. When students are walking around in their leisure and approach the old pictures of the institution, they instantly listen to the institution history. Upon seeing the artwork, one can quickly understand the artistic concept. The M7C can store 9,999 paragraphs of informative notes, which is enough to hold even the most displays in the institution. Students can choose the material pertaining to their major to listen to, without needing to follow the crowd, which makes their learning efficiency much higher.
When conducting academic and research exchanges, the team discussion mode comes in handy. Educators or experts can bring a transmitter to explain to instructors, students and visitors simultaneously, and several people can also work together—for example, a history instructor can explain the history of the times, and an art instructor can supplement the style of the works, making the content more thorough. With 180 channels, multiple academic and research teams can run simultaneously without interfering with each other, and the institution’s capacity to receive outside exchange groups has also been improved.
International academic and research exchanges are also convenient. M7C can be used in multiple languages. International exchange students and visiting scholars can understand the language they know without needing to find a translator especially, which saves a lot of trouble. The operation of the equipment is really straightforward. Students and instructors can use it without learning. Whether they are elderly or young, they can all start easily.
The monitoring equipment of the institution is also convenient. The specialized storage box can hold 40 tour guide devices each time, and there is also a dedicated area for charging cables, which does not occupy much space. The USB charger can charge up to 10 devices each time. Simply plug it in and it can be used flexibly in classrooms and event halls. The equipment is shockproof and durable, so students don’t need to worry about it breaking. Combined with the after-sales service of Yingmi, institutions can use it with great ease.
