Now wireless tour guide systems are being widely adopted in practical training courses at universities, skill training sessions in vocational institutions, and multilingual classes in language schools. Even cadre education and training classes at Party Schools rely on this device to make the delivery of teaching information smoother. Most communication troubles in traditional classrooms can be easily solved with wireless tour guide systems, and choosing a model tailored to teaching scenarios is the key to a tangible boost in classroom efficiency.
Key Communication Pain Points Hindering Classroom Efficiency
In various teaching scenarios, unclear and inadequate audio transmission is a major barrier to classroom efficiency, especially prominent in large-class teaching and mobile teaching. In large classes, when teachers rely solely on their voices or ordinary megaphones to give lectures, students in the back rows often struggle to hear clearly or fully. As a result, key knowledge points fail to be delivered effectively, students’ attention drifts easily, and classroom interaction is greatly reduced. What’s more, when multiple classes are held simultaneously on the same floor or in adjacent areas, the sound from megaphones interferes with each other. This not only disrupts classroom order and irritates both teachers and students, but also inevitably impairs teaching effectiveness.
Furthermore, in mobile teaching scenarios such as practical training classes in vocational colleges and outdoor study tours, teachers’ explanations cannot be transmitted to every student in real time. When students are scattered for hands-on operations, they tend to miss critical operational points, leading to a sharp drop in the efficiency of teaching guidance. In multilingual classrooms, there is an inherent shortage of professional teachers for minor languages, making one-on-one tutoring impractical. Traditional audio playback lacks flexibility and cannot meet students’ needs for real-time questions. Additionally, teachers who use handheld megaphones for long periods are restricted in their movement and prone to vocal fatigue, which compromises the quality and coherence of their explanations.
Yingmi K8 Wireless Tour Guide System: A Professional Choice for All Teaching Scenarios
With 18 years of deep expertise in the tour guide device industry, Yingmi has launched the K8 Wireless Tour Guide System, which is fully optimized in functionality to address the aforementioned pain points in teaching. It is an ideal choice for universities and training institutions looking to enhance classroom efficiency. Having stood the test of the market, the Yingmi K8 is exported to dozens of countries worldwide, boasting stable and reliable performance with core functions perfectly aligned with the actual needs of teaching.
Equipped with automatic binding technology, the receiver requires no manual channel adjustment. Once the transmitter is unlocked and powered on, the receiving headsets pair with it automatically. This zero-learning operation saves plenty of preparation time before class for both teachers and students. The transmitter supports one-to-many pairing without interference, suiting classes of all sizes. Its 65-channel design ensures independent signal transmission for simultaneous teaching in multiple classes, eliminating cross-interference. Operating on the new-generation mobile high-frequency band of 860MHz-870MHz, the system features significantly enhanced anti-interference capability and high sound fidelity, enabling clear audio transmission even in noisy practical training workshops or areas with multiple classrooms.
The receiving headsets of the Yingmi K8 adopt a non-in-ear earhook design and weigh only 22 grams, allowing students to wear them comfortably all day while solving hygiene issues related to shared use. The receiver supports customizable volume and squelch levels, catering to the different auditory needs of individual students. Powered by a high-performance polymer lithium battery, the device offers 7 to 8 hours of usage on a single charge, fully covering a full day of teaching. With a transmission range of 200 meters, it enables hassle-free mobile explanations for practical training and outdoor classes. Moreover, the Yingmi K8 features audio storage: teachers can pre-record explanations of key knowledge points, and the device will automatically play the audio on the pre-set channel when powered on. This function is ideal for multilingual teaching and repeated explanations of key content, effectively alleviating the shortage of teachers. The accompanying professional contact-type charging box features a metal casing for fire and safety protection, and it can charge and store multiple devices in bulk, making school management extremely convenient. An optional ultraviolet disinfection function further improves the hygiene of device use. In addition, Yingmi provides a 2-year product warranty, offering comprehensive after-sales support for educational use.
Yingmi K8 Empowers Classrooms: Four Solutions to Boost Efficiency
The Yingmi K8 Wireless Tour Guide System offers targeted solutions to the various challenges in classroom teaching, fundamentally improving teaching efficiency. For large-class teaching, teachers can use the K8 transmitter with lavalier or headset microphones, and their explanations are transmitted directly to students’ receiving headsets via wireless signals. This directional and clear audio transmission eliminates the problem of poor audibility in the back rows, helping students focus more on absorbing knowledge and significantly raising their classroom attention.
For simultaneous teaching in multiple classes, the K8’s multi-channel and strong anti-interference design allows each class to use an independent channel. Even in adjacent classrooms, there is no audio cross-interference, so each class can maintain an independent teaching order. Teachers no longer need to raise their voices, enabling a more relaxed teaching state. In mobile teaching scenarios like practical training and outdoor study tours, the stable 200-meter transmission range allows teachers to move freely while giving guidance. No matter which operational area students are in, they can clearly hear explanations and key operational points. This not only extends teaching guidance to every student and boosts efficiency, but also reduces safety hazards caused by students’ operational errors.
In multilingual teaching, teachers can pre-store audio explanations of knowledge points in different languages on the K8. Students can listen to authentic explanations in their target language via the receiver, which not only solves the shortage of teachers for minor languages but also allows students to replay the content as needed, enhancing the effectiveness of language learning. Meanwhile, the K8’s bulk charging and storage design streamlines school device management, eliminating the need for a large amount of manpower for charging and organizing devices, and thus reducing teaching management costs.
