Infrared cordless microphone.

摘要

An infrared-ray cordless microphone comprising a modulator for modulating an acoustic-to-electric converted sound signal through a predetermined process; and an infrared-ray transmitter for transmitting an output infrared signal obtained by converting the modulated sound signal from the modulator; wherein the infrared-ray transmitter is disposed at a lower end of the microphone body. There is also provided an infrared-ray cordless microphone system consisting of such microphone and a sound output means which comprises an infrared-ray receiver for receiving the infrared signal from the microphone, a demodulator for demodulating the received infrared signal, and an electric-to-acoustic converter for converting the demodulated signal into a sound signal.
