When encountering international scientific research teams, due to the language barrier, they could only take pictures of the glacial landforms and had no idea about the geological causes behind them at all. This is not an isolated case. Whether it is high mountains and deep valleys, forests and wetlands, grasslands and deserts, the interpretation work in nature reserves always cannot avoid the problems of “not being able to reach far, being easily disturbed, being difficult to meet the needs of multiple languages, and not being durable outdoors”. With 18 years of experience in outdoor tour guide device, Yingmi has made the interpretation in nature reserves not only impart knowledge but also not disrupt the ecological tranquility, thus becoming the choice of more and more scenic spots.

I.Core Pain Points of Nature Reserve Explanation
The interpretation scenarios in nature reserves are completely different from those in museums and indoor exhibition halls. With vast Spaces, complex terrains, and the need to be extremely cautious in protecting the ecology, ordinary wireless tour guide devices often fail when they arrive here. The main problems are concentrated in these aspects:
1.It can’t be transmitted far and the outdoor signal is always disconnected
Nature reserves often cover several square kilometers, and the visiting routes are often several kilometers long, interspersed with complex terrains such as mountains, forests and canyons. The effective transmission distance of ordinary wireless tour guides is mostly less than 100 meters. When they are blocked by forests or separated by slopes, the signal immediately weakens, and there is often a disconnection between tour guides and tourists. Especially when the scientific research team moved into the heart of the protected area, as soon as the explanations stopped, the ecological knowledge and key points of the scientific research that should have been passed on were also interrupted.
2.Multiple teams interfere with each other, disrupting the tranquility of nature
The core of nature reserves is to protect the ecology. Excessive human noise can disturb wild animals. The sound of traditional loudspeakers travels far. When several groups visit at the same time, the explanations of different tour guides mix together. Not only can tourists not hear clearly, but the birds and beasts in the mountains are also easily frightened and run around in all directions. Some wireless audio guides fail to do a good job of channel isolation. Signals from different teams may also be mixed up, with each team listening to the other. The more they are used, the more chaotic it becomes.
3.The demand for multiple languages cannot be met, and international tourists can only watch the spectacle
Nature reserves often receive international scientific research teams and ecology enthusiasts. These visitors particularly need explanations in multiple languages. However, most of the protected areas are located in remote areas, making it extremely difficult to gather enough guides who speak minor languages. Most ordinary audio guides can only speak one language. The language barrier prevents international tourists from deeply understanding the ecological value and cultural connotation of the reserve. They can only take pictures of the beautiful scenery and fail to see the core highlights at all.
4.It is not durable and cannot withstand harsh outdoor environments
The weather in the nature reserve is changeable. One moment it’s scorching hot and sunny, the next it rains and fogs up, and it’s full of dust. The materials and protective designs of ordinary wireless audio guides are made for indoor scenarios. When used outdoors, they either get wet or the battery doesn’t work, and the buttons are prone to malfunction. However, there are hardly any maintenance service points in the protected area. When equipment breaks down, it cannot be repaired in time, which directly reduces the visiting experience of tourists.
5.The service model is too monotonous, leaving both group and individual customers unable to take care of each other
Visitors to nature reserves are divided into two categories: study tour groups and scientific research groups. These group visitors need to listen to the explanations along with the tour guide. Individual tourists, on the other hand, prefer to stroll leisurely on their own, listening whenever they want and stopping whenever they want. Ordinary wireless tour guide devices either only allow teams to listen simultaneously or lack the function of self-guided Tours, thus failing to meet both types of demands at the same time, resulting in always loopholes in the services of scenic spots.

Ii. Detailed Explanation of Core Products: Covering all scenarios
Yingmi has specially developed two core products for different types of tourists in nature reserves, respectively solving the interpretation problems of group and individual tourists. The parameters and functions are precisely adapted to outdoor scenarios and are particularly convenient to use.
1.Yingmi R8 Team Tour Guide System: The “Silent Magic Tool” for Multi-team Outdoor Explanations
For group tourists such as study Tours, scientific research groups and tour groups in nature reserves, the Yingmi R8 team tour guide system is simply tailor-made. Its most core advantage is “noise-free and interferon-free”, which fully meets the ecological protection requirements of nature reserves – the tour guide wears a transmitter to explain, and tourists hang receivers to listen. The sound is only transmitted within a small range and will not spread out, so there is no need to worry about disturbing wild animals anymore.
In terms of signal performance, the R8 has been specifically optimized for complex outdoor terrains. It uses GFSK modulation technology, which has an extremely strong anti-interference ability. The effective transmission distance can reach 180 meters. Even in areas with dense forests and undulating slopes, the signal can remain stable and fully cover the long-distance tour routes in nature reserves. Moreover, it has 100 adjustable channels. Different teams can choose different channels. Even if dozens of teams are traveling in parallel in the same area, the signals will not be interfered with, and each team can hear clearly.
The durability for outdoor use is also maximized: the entire machine weighs only 18 grams, adopts Ergo ergonomic design, and is worn on the ear hook. It won’t feel stuffy or painful even after long-term use, making it suitable for both the elderly and children. The fuselage is made of durable materials and has basic water and dust resistance capabilities, capable of coping with the damp and dusty environment in protected areas. It is equipped with a built-in polymer lithium battery. Once fully charged, it can be used continuously for over 8 hours, which is sufficient to support a full day of outdoor explanations, eliminating the need to frequently look for places to charge it.
The operation is also particularly simple, with just one SET button. Once the power is turned on with one click, dozens of receivers can be synchronized and paired immediately. Whether it’s an experienced tour guide or a volunteer who has just started up, they can figure it out in just a few minutes. The device screen displays the channel, volume and battery level in simple graphics, allowing you to clearly see the status at a glance without having to ponder over those complex parameters.

2. Yingmi i7 Self-service Tour Guide System: The “Intelligent Guide” for Individual and International Tourists
For individual and international visitors to nature reserves, the Yingmi i7 self-service tour guide system offers a more flexible solution. It is an automatic sensing design. When tourists walk within 1 to 3 meters of the designated area, the device will automatically trigger the corresponding explanation content without manual operation. This not only conforms to the rhythm of individual tourists’ independent sightseeing but also ensures that no key information is missed in the explanation – for example, when they reach the rare plant area, the types, growth habits and protection value of the plants will be automatically played. When we turned to the geological wonders, the principle of landform formation was explained. We gained a lot from the tour.
Multilingual support is a major highlight of the i7. It comes with 8 commonly used languages built-in, including English, Japanese, Korean, French, etc., perfectly solving the problem of shortage of minority language guides in nature reserves. International tourists only need to choose the language they are familiar with to gain a deep understanding of the ecology and culture of the protected area, without having to guess blindly by looking at the information boards with translation software. Moreover, it adopts intelligent noise reduction technology and can adjust the volume in 32 levels. Even if there are group tourists speaking nearby, the explanations in the headphones can still be clearly distinguished.
The outdoor usage experience has also been meticulously detailed: the entire machine weighs 18 grams, and the soft silicone ear hooks can be rotated and adjusted. Regardless of the size of the ears, they can stick steadily. They are not easy to fall off even when running or jumping, and the ears won’t get sore after a whole day of use. It can last for over 8 hours on a single full charge, which is fully capable of meeting the all-day visiting needs of tourists. With self-service rental cabinets, tourists can rent one within 30 seconds by scanning the code. Any rental cabinet can be returned, and the deposit will be refunded instantly, eliminating the trouble of staff going back and forth.
What’s more considerate is that the rental cabinet also comes with an ultraviolet disinfection function. After the equipment is returned, it will automatically disinfect for 30 seconds, with a high rate of killing bacteria, ensuring hygiene. The back-end of the scenic area can also display the inventory, battery level and fault status of the equipment in real time. If there are any problems, it will automatically remind you, eliminating the need for staff to check each one individually and saving a lot of manpower.

Iii. Yingmi’s full-cycle solution, making cooperation extremely worry-free
When choosing a wireless audio guide, it is not only about whether the product itself is user-friendly or not, but also the subsequent service and customization capabilities are very crucial. Yingmi provides full-cycle services from selection, installation and commissioning to after-sales maintenance for nature reserves, ensuring that the cooperation process involves fewer detours and less worry.
1.Customized adaptation: Adjust according to the scene, making it more convenient to use
Yingmi will make optimizations based on the specific conditions of nature reserves: for instance, for reserves with particularly large areas, it will enhance the signal module of the product to further improve the transmission stability. For high-altitude and low-temperature areas, upgrade the low-temperature endurance battery of the product to ensure normal use in low-temperature environments. For protected areas with many ecologically sensitive zones, adjust the sensing range of the product to prevent tourists from mistakenly entering prohibited areas due to equipment guidance. If necessary, the scenic area can also provide individual color matching and silk-screen printing of logos for the equipment, which is more in line with the image of the scenic area.
2.Omni-channel service support: Respond nearby without waiting
No matter where the nature reserve is located, you can enjoy nearby services – if the equipment malfunctions, the after-sales team can quickly come to your place for repair or replacement. If you have any questions during use, just make a phone call or contact the online customer service for immediate answers. You don’t have to wait for a long time for no one to respond. If it is a cooperation with overseas nature reserves, Yingmi also has a complete international logistics and after-sales network to ensure the smooth delivery and normal use of the products.
3.Flexible cooperation model: Regardless of the budget, there are suitable solutions available
Due to the different scales, visitor flows and budgets of nature reserves, Yingmi offers various cooperation models such as sales, leasing, joint operation and self-operation under contract. Large protected areas with high foot traffic and frequent usage are suitable for the procurement model, and it is more cost-effective to hold the equipment for a long time. For small and medium-sized protected areas with large fluctuations in passenger flow and limited budgets, the rental model is more flexible. During peak seasons, more units can be rented, and during off-peak seasons, fewer units can be rented to reduce operating costs. The joint operation and contracted self-operation models do not require scenic spots to worry about equipment management. Yingmi is responsible for maintenance, updates and operation. Scenic spots only need to share the profits, which is both worry-free and labor-saving.
