Wireless microphone

Wireless microphones are used with audio equipment to allow a performer to utilize an amplification system without having to have the microphone attached to an audio amplifier by a wire. A wireless microphone serves to convert a sound wave signal into an electronic signal having frequencies in the zone of an FM signal to be sent to a FM receiver provided in audio systems, and the signal outputted from the wireless microphone is also output through a speaker provided within or outside the system. A wireless microphone transmits electric wave containing an audio signal to a receiver unit. The receiver unit includes a tone signal detection circuit for detecting the tone signal, a noise detection circuit for detecting the noise signal, and a signal level detection circuit for detecting the signal level. Wireless microphone systems used in a concert halls, live stages or wayside recording are roughly classified into two types: hand-held microphone transmitter systems and belt pack microphone transmitter systems. Wireless microphones require batteries to power their electronic components such as their transmitters. Wireless microphones can be used for example in vehicles in association with cellular phones, in portable video cameras, computers, and other multi-media devices, as well as other two-way communication devices such as aircraft headsets. A wireless microphone is generally equipped with an on/off switch, and a mute switch, which are used to deactivate the microphone selectively.
