Nowadays, numerous cultural and museum institutions in China, such as Henan Museum, Guizhou Geological Museum and China National Museum of Ethnology, are striving to enhance visitors' experience. Self-guided audio tour systems have long become a standard feature of modern museums. With 19 years of solid experience in the audio tour and exhibition industry, Yingmi has an in-depth understanding of the needs of cultural and museum venues. We have specially developed self-guided audio tour solutions tailored for museum scenarios, which not only allow visitors of all ages and nationalities to fully immerse themselves in the charm of museum collections, but also help museums ease operational and management burdens and improve overall efficiency.

Existing Pain Points of Self-Guided Audio Tours in Museums
At present, the self-guided audio tour services of many museums still have many problems that not only affect visitors' experience but also create extra troubles for venue operations. Professional guided tour resources are always limited. During peak tourist seasons and holidays, it is a common occurrence for visitors to queue up for guided tours, and sometimes multiple groups of visitors crowd together to listen to the commentary, resulting in a poor experience. Moreover, the shortage of interpreters proficient in small languages is a prevalent challenge across the industry, making it difficult to meet the needs of foreign visitors. Even if museums hire such interpreters at a high cost, it will drastically increase their operational expenses.
Traditional audio tour devices also have notable technical shortcomings. Some devices feature low induction accuracy; in exhibition areas with densely displayed exhibits, signals from adjacent exhibition spots are prone to mutual interference, leading to incorrect or skipped commentary playback and significantly ruining visitors' experience. Other devices are overly complicated to operate, leaving elderly and foreign visitors struggling to use them, which instead becomes a hindrance to their visit. In addition, issues such as insufficient battery life and inconvenient post-use management and maintenance prevent the self-guided audio tour services of museums from playing their intended role effectively.
Yingmi M7: A Custom Self-Guided Audio Tour Device for Museums
Targeting the unique scenarios and practical needs of museums, Yingmi has launched the M7 chest-worn fully automatic induction audio tour player—a dedicated self-guided audio tour device designed for cultural and museum institutions, which is highly compatible with the exhibition layout and visitors' viewing habits of museums.
Equipped with an RFID-2.4G interference-free star topology system, this player fundamentally resolves the industry-wide issue of signal interference in exhibition areas. It can accurately switch signals within a range of about 1 meter, ensuring precise triggering of the corresponding commentary even in small exhibition areas with densely arranged exhibits. Its casing is crafted with a pure white baking paint finish, boasting a simple and elegant design that blends seamlessly with the exhibition environment of museums. The chest-worn design is lightweight and comfortable, without interfering with visitors taking photos or pausing to admire exhibits in detail.
The M7 player comes with 8 built-in languages for commentary and also supports custom language options, which fundamentally addresses the pain point of small language commentary in museums. Visitors of different nationalities can select their familiar languages to listen to authentic and professional commentary on the collections. Adopting a digital voice storage mode, the device completely overcomes the drawbacks of traditional storage media, such as easy wear and tear and voice distortion, ensuring clear and pure commentary sound quality. It also supports fast content update via USB connection, allowing museums to modify commentary in real time when updating exhibits or holding temporary exhibitions, offering great flexibility. There is no need to worry about battery life either: the M7 receiver has a working time of more than 16 hours, and the transmitter has an even longer battery life, which fully meets the all-day operation needs of museums and eliminates the risk of device shutdown during visitors' tours.

Comprehensive Self-Guided Audio Tour Solutions for Museums with Yingmi M7
Precision Sensing Solution for Exhibition Halls
Museums feature exhibition halls of varying sizes and exhibit densities. In response to these differences, Yingmi M7 allows for customized layout planning of signal transmitters based on the actual situation of the venue, with an adjustable coverage range of 0.5 to 40 meters. Whether in large general history exhibition halls or small thematic exhibition areas, the system can automatically play the corresponding commentary when visitors approach an exhibit and stop when they leave, aligning the commentary perfectly with visitors' viewing routes and thoroughly resolving the problems of signal interference and skipped commentary playback.

Multilingual Content Management and Update Solution
Yingmi provides exclusive commentary production and update services for museums. We not only assist in recording and importing multilingual commentary but also realize data compression and storage through a standardized voice coding format. Museum staff can complete real-time commentary updates for all on-site devices simply via USB connection. The operation is simple and efficient, without the need for professional technical personnel, which greatly reduces the content management costs of museums.
Device Management and Support Solution
Yingmi has paired the M7 player with a full set of device management accessories. The HM-EB36/HM-EB48 contact charging case can charge 36 or 48 devices simultaneously. Adopting an intelligent charging management mode, it enables fast and safe charging while significantly extending battery life, and it also offers an optional UV disinfection function that perfectly meets the hygiene and epidemic prevention requirements of museums. The HM-50S dedicated storage case is made of aluminum alloy and can hold 50 sets of devices at a time. Built-in silicone grooved padding and sponge cushioning facilitate the storage, transportation and handling of the devices, effectively reducing equipment wear and tear. In addition, the M7 player comes with a 2-year product warranty, and our professional technical service team is always on hand to solve various problems encountered during the use of the equipment for museums.
User Experience Optimization Solution for All Age Groups
Weighing only 50 grams in total, the chest-worn M7 player is suitable for visitors of all age groups, making it easy for both the elderly and children to use. Furthermore, the device requires no manual operation and plays commentary automatically through induction, completely lowering the usage threshold. This allows all visitors to focus on their visit and truly enjoy an immersive cultural and museum experience.
