The tour guide explanations are well-organized, and travel agencies find it more

 News     |     March 13, 2026

The frequent occurrence of multi-tour explanation chaos has hindered the professionalism of travel agencies due to details.

 
In the tourism industry, tourists' evaluations of travel experiences often lie in the unnoticed details. The problem of multiple tours clustering together under the traditional explanation mode seems like a minor inconvenience, but in fact, it is the key factor that lowers service quality. Many travel agencies do not pay attention to the selection of explanation equipment and blindly use old-fashioned ordinary equipment. As a result, during peak seasons when multiple tours are received, various problems cluster and arise, which not only disrupts the tour guiding rhythm but also consumes the energy of the tour guides, and makes tourists feel less professional.
 
The most common problem is the interference problem. In popular scenic areas, multiple teams visit the same area, and the old-fashioned explanation equipment has extremely poor anti-interference ability. The explanations of adjacent teams interfere with each other, and tourists wearing the equipment cannot hear the content of their own tour guide's explanation clearly. Their ears are filled with a chaotic noise, and the cultural explanation becomes a noisy sound. Tourists are completely confused throughout the process, the enjoyment of the trip is greatly reduced, and after the tour, they keep making jokes and even file complaints. The reputation of the travel agency is directly affected. Tour guides will also be disrupted by the interference in their explanations, and the content they prepared cannot be smoothly conveyed. Their working state is also affected.
 
The second problem is the shortage of channel resources. Many ordinary explanation devices on the market have very few adjustable channels. During peak hours, when more than ten teams are using them simultaneously, there are simply not enough channels to allocate. Either multiple teams share one channel, which aggravates the interference, or the tour guide repeatedly pauses the itinerary to adjust the channel, seriously delaying the overall itinerary rhythm. The waiting time for tourists becomes longer, and the experience is naturally not good. Moreover, the old-fashioned equipment is cumbersome to operate. Every time they conduct a tour, they have to manually pair and adjust the frequency. The tour guide has to spend a lot of time on equipment debugging, which makes it impossible to focus on the team and serve the tourists.
 

Yingmi L7 breaks through the problem and makes multi-tour explanations orderly and more professional

 
Since Yingmi was established in 2007, it has been dedicated to the research and production of explanation devices for 19 years. It has been deeply researching the practical pain points of travel agency multi-tour operations on the front line of tourism tours. Yingmi is very clear about every detail of travel agency multi-tour operations. The L7 team explanation system does not do any fancy functional packaging. All configurations are tailored to the actual usage needs of travel agencies. From signal anti-interference, channel configuration, operation convenience to equipment management, it fully solves the chaos of multi-tour explanations and makes travel agency tours more convenient and presents a higher level of professionalism externally. What is more in line with the needs of travel agencies is that L7 supports 150 adjustable independent channels, which can fully meet the demand of accommodating dozens of groups simultaneously during peak seasons. Each group can be assigned its own dedicated independent channel, eliminating the worry of insufficient channels. The tour guide only needs to simply set up the corresponding channel in advance, and the device can quickly adapt upon startup without the need for repeated debugging and tinkering. The multi-group scheduling becomes exceptionally simple, completely eliminating the previous situation of insufficient channels and constant interference.
 Easy-to-Operate Tour Guide System

Simple operation + lightweight design, making tour guiding more worry-free

 
First-line tour guides have a fast-paced working rhythm and have no time to deal with complex equipment. Yingmi L7 adopts a minimalist operation logic throughout, completely abandoning the cumbersome pairing and debugging steps of old equipment. The transmitter can be quickly started by pressing the button, and the receiver will automatically search for and pair with the corresponding channel upon startup, without the need for the tour guide to guide tourists to operate one by one. Even when leading elderly groups or family groups, tourists can directly use the equipment after receiving it, significantly saving the preparation time before the team departs and directly improving the tour guiding efficiency.
 
The transmitter is compact and lightweight, and even when held for a long time, it won't feel tired. It is also equipped with a high-definition LCD display, making the channel information, remaining battery power, and signal strength clear at a glance. The tour guide can always keep track of the equipment status and quickly complete channel switching. The receiver adopts a 15g ultra-lightweight ear-mounted non-in-the-ear design, making it comfortable to wear without any burden, and tourists won't have ear discomfort even when wearing it for a long time. The optimization of details enhances the tourist experience and also reduces the additional communication costs for the tour guide, eliminating the need to repeatedly remind tourists to adjust the equipment.
 

Integrated storage + fast charging + long battery life, zero burden for batch management

 
To address the problem of difficult equipment management for travel agencies when organizing multiple groups, L7 is equipped with an exclusive 50-slot integrated charging storage box. One storage box can neatly store 50 sets of equipment. The internal space is specially positioned with dedicated card slots, ensuring stable placement of the equipment during transportation and storage. It can effectively prevent shock and drop during transportation and storage, avoiding damage from collisions. After the trip, the tour guide doesn't need to count and organize the equipment one by one. They can directly recycle and put it into the storage box, completing the final work in just a few minutes, saving a lot of time and energy.
 
This storage box also supports batch fast charging function, capable of charging 50 receivers simultaneously, eliminating the cumbersome process of individual charging. The charging efficiency is significantly improved. The battery life of L7 is fully compatible with the all-day tour guiding needs of travel agencies. The transmitter and receiver require only 2.5 hours of charging per charge to work continuously for 6-8 hours, covering the duration of multiple group relay tours throughout the day. There is no need for charging or battery replacement during the journey, completely eliminating the tour guide's concerns about battery endurance, and allowing them to focus entirely on tour guiding services.
 

Flexible adaptation for all scenarios, covering all types of tour groups of travel agencies

 
The types of tour groups of travel agencies are diverse, including regular sightseeing tours, museum and cultural study tours, government and enterprise reception tours, and niche deep-reading tours, etc. The guiding scenarios and requirements for different tour groups are all different. L7 has strong scene adaptability. Whether it's an open outdoor scenic area or a closed indoor exhibition hall, the signal transmission distance can reach up to 200 meters, maintaining stable transmission even through walls and over long distances, without any signal interruption or unclear sound quality.
 
At the same time, L7 supports one-to-many and many-to-many guiding modes. The main and deputy tour guides can seamlessly switch the guiding authority, meeting the needs of guiding and collaborative tour organization for large groups. No additional equipment replacement is required. One device can cover all tour groups and scenarios of travel agencies, eliminating the need to purchase equipment separately for each scenario. This not only reduces the overall procurement cost but also simplifies the equipment management process, making the operation of travel agencies more efficient and the professional image more unified.
