ABSTRACT:
A voice sound transmitting unit having an earpiece that is adapted for insertion into the external auditory canal of a user, the earpiece having both a bone conduction sensor and an air conduction sensor. The bone conduction sensor is adapted to contact a portion of the external auditory canal to convert bone vibrations of voice sound information into electrical signals. The air conduction sensor resides within the auditory canal and converts air vibrations of the voice sound information into electrical signals. In its preferred form, a speech processor samples output from the bone conduction sensor and the air conduction sensor to filter noise and select the a pure voice sound signal for transmission. The transmission of the voice sound signal may be through a wireless linkage and may also be equipped with a speaker and receiver to enable two-way communication.
