WIRELESS HEAD SET APPARATUS EQUIPPED WITH A MICROPHONE COMBINED WITH AN EARPHONE, INCLUDING A MONITORING FUNCTION

摘要

PURPOSE: A wireless head set apparatus equipped with a microphone combined with an earphone is provided to minimize the exposure of a received signal to external noises by mounting a receiver in an ear.;CONSTITUTION: A vibrating sensor microphone(110) includes a single crystal vibrating sensor(111) and a converting module(113). The single crystal vibrating sensor senses the vibration of voice cords transferred to the inside of an ear. The converting module converts the sensed vibration into an electrical signal. A monitoring microphone(140) outputs an external sound signal. A receiver(120) converts an external communicating signal into a sound signal. A controlling module(130) transmits the electric signal of the vibrating sensor microphone to an external communicating unit.;COPYRIGHT KIPO 2011
