ABSTRACT A vibration pick-up mechanism for picking up a bone conductive voice signal from an external auditory canal wall, and a speaker for converting the received signal into a voice are contained in one ear piece to enable a bidirectional speech in a hand free state. A duct communicating between the inside and the outside of the ear is formed at the time of attaching the earpiece in the earpiece to eliminate an increase in the sound pressure in the ear, thereby hearing an external sound in the ear.
