Finally, the high frequency signal is transmitted through the antenna into the air.
We design the transmit frequency in the FM radio band, so we can receive the high-frequency signal with any FM radio and restore the sound signal from the high-frequency signal for various purposes.
The receiving portion of the wireless microphone is generally powered by the mains, and the receiving antenna receives the radio wave emitted by the transmitting portion, and is processed by the internal circuit to extract the audio signal, and is sent to the sound reinforcement system through the output signal line, thereby completing the audio signal.
