A wireless microphone is an audio device that transmits sound signals to a recording or amplification system without a physical cable. It works by using a transmitter to convert audio into a radio frequency (RF) signal, which is then picked up by a receiver and converted back into sound.
Core Components
A complete wireless microphone system typically consists of three primary parts:
Microphone: The input device that captures acoustic sound and converts it into an electrical signal.
Transmitter: Converts the electrical signal into a radio signal. This can be built into a handheld mic or housed in a separate "bodypack" clipped to a belt.
