ABSTRACT:
An ear microphone for an external auditory canal insertion type two-way communication earpiece. Within the casing of the earpiece a fixed electrode and a vibrating electrode are positioned in capacitive relation with each other, the vibrating electrode for detecting acceleration vibration from outside the casing in the form of bone-conducted voice sound vibration within the external auditory canal. Electrical signals transduced from picked-up voice sounds pass through an impedance conversion circuit mounted in the ear microphone.
