What is a wireless microphone?
The electronic component microphone (microphone) on the circuit board first converts the sound signal of nature into audio frequency electrical signal, which will be used to deploy the high-frequency signal caused by the electronic component oscillator. Finally, the high frequency signal is sent to the sky according to the wireless antenna.
We will send the frequency design scheme in the stock band of FM radio, so that we can cooperate with all FM radios to receive the high frequency signal, and recover the sound signal from the high frequency signal for various main purposes.
