digital wireless microphone

A microphone is a transducer that converts sound into electronic signals. It can transmit human speech to electronic devices to distant places or amplify the sound signal through speakers. In recent years, the development of wireless technology has gradually matured and become an indispensable trend in daily life, such as WIFI, Bluetooth and 2.4GRF transmission, etc., which have brought many conveniences in life, and wireless microphones are also one of them, allowing microphone users such as teachers to attend class. It is more convenient to go out with a tour guide to introduce attractions, speakers and karaoke singing.
