The tour guide device cracking team explains difficult problems

 News     |     April 21, 2026
The problems of unclear explanations during multiple-person travel have become prominent, and traditional methods are unable to break through the bottleneck.

Problem 1: Remote locations + noise interference, explanations are "incomprehensible and incomplete"

 
When multiple people travel, the physical conditions and paces of team members vary, often resulting in long queues. Members in the front can clearly hear the explanations, while those in the back can only hear fragmented and vague snippets, or even nothing at all. Coupled with external disturbances such as the noisy crowd in the scenic area, traffic noise, and echo in the venue, the interpreter needs to repeatedly increase the volume and repeat the explanations, which not only increases the interpreter's burden but also makes team members lose patience in listening to the explanations. The original cultural sightseeing and knowledge dissemination become a "quick glance".
 

Problem 2: Interference from multiple teams, chaotic explanations

 
In popular places such as scenic spots and museums, there are often multiple teams conducting explanations simultaneously. Traditional amplification equipment has no anti-interference function, and the explanations of different teams overlap and mix, making it impossible for team members to distinguish their own team's explanations and causing chaos in the scene. This can even lead to unnecessary conflicts between teams and seriously affect the comfort and experience of the trip.
 

Problem 3: Inconsistent explanations, frequent team disconnection

 
When multiple people travel, some members may stop to take photos or visit exhibits, resulting in disconnection from the main group and being unable to hear the explanations in time. Later, they also have difficulty keeping up with the explanation rhythm, only missing key explanations. And the interpreter cannot attend to every member, either stopping to wait and affecting the overall progress, or continuing to explain and causing disconnection members to miss key points, getting into a "dilemma".
 Stable Tour Guide System

The Yingmi L7 tour guide device comes to the rescue, precisely solving the problems of unclear explanations during travel.


Multi-channel anti-interference, worry-free for multiple teams to explain simultaneously

 
For the interference problem when multiple teams explain simultaneously, the Yingmi L7 tour guide device is equipped with a multi-channel design, with 1-150 channels that can be adjusted. Different teams can choose different channels to achieve signal isolation and avoid interference. This design perfectly suits scenarios with multiple teams gathering, such as in scenic spots and museums. Even when multiple teams are conducting explanations simultaneously, the explanations of each team can be clearly transmitted without any mixed sounds, ensuring the explanation order and improving the travel experience of each team. Additionally, L7 adopts CRC digital encryption technology to ensure the security of the explanation channels and prevent the explanations from being interfered with or leaked.
 
Multi-scenario adaptability + flexible kits, meeting the needs of various teams The scenarios of group travel are diverse, and the team sizes vary as well. The Yingmi L7 team explanation system designs various flexible kits for different scenarios and team sizes. From small teams of 20 people to large teams of 500 people, there are suitable solutions available. Among them, a 20-person team can choose a kit with 1 transmitter and 20 receivers, and a 50-person team can be equipped with a charging box for convenient unified charging and management of the equipment. For large teams of 100 or more people, the number of transmitters can be increased to support seamless switching of explanations by 3 interpreters, meeting the needs of multi-interpreter collaboration.
 
Moreover, L7 supports Bluetooth connection, which can be connected to mobile phones, translation devices, etc., suitable for teams with foreign language explanation needs, solving the problem of a lack of foreign language interpreters. The equipment is lightweight, with each receiver weighing only 15 grams. The ear-hanging design is ergonomic and does not cause discomfort even after long-term wearing, making it suitable for teams with long-term travel and visiting needs. At the same time, the charging time of L7 is only 2.5 hours, allowing for continuous operation for 6-8 hours, fully meeting the needs of a day's travel explanation without frequent charging, avoiding any impact on the travel progress.
