<p>An ear piece device (10) configured for being supported in the ear and providing a microphone (17) which is sensitive only to sounds conducted within the skull of the user is contained within a housing (11) which is configured at one end to fit snugly at the ear canal of the user, but not to extend within the ear canal. A microphone element is coupled within the housing. This microphone element includes an inertial platform (30) which has sufficient inertial mass to substantially resist movement associated with the housing by reason of audio vibration and includes signal means for generating a signal representing vibrations transferred into the housing in the form of audio vibrations from the user. This signal is supplied to an audio circuit (68) for processing and reproduction of the user's voice. A speaker element (13) may be included within the ear device and can be decoupled acoustically so as to avoid feedback.</p> |
