In a popular cultural scenic area in Southeast Asia, there used to be a frustrating scene: several tour groups crowded in the same area, and the voices of the wireless tour guide devices interfered with each other, making it difficult for tourists to hear the explanations clearly. What’s worse, the battery life of the equipment was unreliable. It was claimed to last for a whole day, but by mid-afternoon, it had run out of power. The tour guide had to shout loudly, and the tourists’ experience was greatly compromised. Later, the scenic area replaced it with the products of Yingmi. Not only was the signal very stable, but there were no more issues of interference or disconnection. The battery life could truly cover the entire day, and all the CE and RoHS certification documents required for customs clearance were complete. The reception efficiency was improved by 30% at once. In fact, for foreign customers, choosing a wireless tour guide devices processing factory ultimately means choosing reliable quality, a product that is easy to use, and worry-free services. Yingmi, with its full-chain control from research and development to production in its factory, is gradually becoming the preferred choice for more and more multinational buyers.
I. Some problems in purchasing wireless tour guide devices
For foreign customers who need to make bulk purchases, choosing a wireless tour guide device is not just about “able to produce sound”. Many hidden problems often cause the purchase cost to increase secretly.
1.Signal stability
Whether it’s in crowded areas like scenic spots and museums, or in complex building structures, when several teams use tour guide devices simultaneously, ordinary products are prone to interference and sudden disconnection. The explanation content is intermittent, and tourists have a bad experience listening. The tour guide also has to repeat repeatedly. The falsely marked battery life is also a common pitfall in the industry. Some factories claim to last for 10 hours, but in reality, it only lasts for 5 or 6 hours. If there is an all-day tour itinerary or cross-city study activities, the power outage in the middle is a “fatal problem”.
2.Comfort and durability of wearing
Most of the equipment purchased by foreign customers needs to be used repeatedly. If the body is heavy and the material is rough, tourists will feel uncomfortable after wearing for a long time. In addition, the shell is not wear-resistant, and the charging interface is prone to damage, resulting in high costs for subsequent maintenance and replacement. What’s more troublesome is the certification and after-sales issues: some factories cannot provide international-recognized CE and RoHS certifications. The goods cannot be cleared at the port, causing operational delays and additional costs. If the equipment breaks down, the international repair response is slow, and the spare parts cannot keep up, directly affecting normal reception. Besides, many products cannot be adapted to multiple languages or customized with brand logos. It’s difficult to meet the local service needs.
II.Scenario-based Matching: Yingmi Precisely Addresses Cross-border Procurement Needs
A truly reliable wireless tour guide devices processing factory must be able to provide suitable products based on different usage scenarios. Yingmi, relying on its own factory’s research and production capabilities, has launched the L8 team tour guide system and the 008A tour guide system, which can basically cover the core needs of cross-border procurement.
1.Preferred for Team Reception: L8 Team Tour Guide System
Whether it’s group tours in scenic spots, international conference receptions, or enterprise visits and exchanges, the L8 team tour guide system can fit perfectly. It uses the UHF 663-694 MHz high-frequency band for signal transmission and is equipped with Yingmi’s own developed digital anti-interference technology. It can adjust 102 independent channels. Even if 20 teams are using it simultaneously in one area, there will be no interference. Customers who have tried it have given positive feedback.
In terms of design, L8 has indeed considered the demand for large-scale use: the transmitter weighs only 48 grams, and the receiver is even lighter, only 16 grams. It uses high-strength lightweight materials, and the earpiece is designed to conform to ergonomic principles, so tourists won’t feel tired after wearing it for a whole day. The accompanying all-aluminum charging box has silicone grooves, which can charge multiple devices simultaneously, protect the equipment when storing, and avoid wear or damage during transportation or storage. There is no need to worry about battery life, as it can last for more than 8 hours after a single charge. It can cover all-day reception in scenic spots and all-day agendas in meetings. Moreover, its lithium battery has been optimized by the factory’s PMU safe intelligent power management technology, which can prevent explosion and overcharging. It is more reassuring to use.
2.Essential for Outdoor Long-Distance Narration: 008A Wireless Tour Guide System
If there are scenarios requiring long-distance narration, such as outdoor scenic spots, large factory visits, or study tours, the 008A wireless tour guide system performs reliably and can meet the industrial-level stability standards. It uses a 935 MHz – 955 MHz carrier frequency. In an unobstructed environment, the transmission distance can reach over 200 meters. Even if passing through multiple buildings or dense forests, the signal will not be lost. This effectively solves the narration problems in open outdoor areas or complex terrains.
The durability of 008A has been rigorously tested: the body shell is wear-resistant, and it has passed high and low temperature environment tests. Whether in tropical high temperatures or temperate low temperatures, it can be used normally. The lightweight design of 50 grams combined with a comfortable earpiece makes it unlikely to fall off even during long outdoor activities. The battery life is also its highlight. The 600mAh lithium battery can support continuous operation for more than 12 hours. Combined with the all-aluminum shock-proof storage box, there is no need to worry about equipment damage during batch transportation or outdoor use. Now this product has been exported to Europe and Southeast Asia for many years, and it has a good reputation in various outdoor reception scenarios.
