Before the technology was not so advanced, explanation devices were generally 'little bees' or loudspeakers. Although these traditional amplification devices could amplify sound and were relatively convenient to use, their drawbacks were also quite obvious. Therefore, people gradually chose the new wireless explanation devices to replace the traditional ones.
1. Transmitter: The transmitter is used by the person who needs to speak. It comes with an ear hook, and of course, it can also be handheld. The speaker can talk into the microphone at a normal volume with the transmitter, solving the noise problem brought by 'little bees', as well as the problems of shouting and sore throat.
2. Receiver: The person who needs to listen wears the receiver, and everyone wearing a receiver can clearly hear the voice of the speaker with the transmitter, as if he is speaking right next to their ear! This solves the annoyance of not being able to hear from the back rows.
3. Charging Box: The charging box has an integrated design with ultraviolet light and negative ion functions, capable of charging 52 receivers and 2 transmitters at the same time.
Up to now, from wired wearable design to wireless integrated design, from bulky and complex to small and exquisite, from ears to hanging, from manual cleaning to automatic disinfection, wireless explanation devices have continuously enriched categories, improved application scenarios, and optimized details, evolving into high-tech products with a sense of design. As a modern, intelligent communication tool, wireless explanation devices are gradually showing their unique charm and wide application value in various fields.
