Abstract: A microphone structure and method of operation that senses a user's speech as represented by vibrations of the jaw sensed by an electrically passive component mounted on a user's tooth. A permanent magnet is attached to the user's tooth and vibrates as the user's tooth and jaw vibrate in response to the user's speech (or other sounds). A coil senses changes in the magnetic flux in proportion to the vibration of the magnet and thus senses the user's speech. No wired connection is required to sense the vibrations of the tooth/jaw as compared to prior techniques and no electrical power is required within the user's mouth as compared to prior techniques.

Abstract: A wireless personal communication system includes an earpiece, worn in or behind the ear, that communicates wirelessly with a remote processor unit (RPU) worn at the neck. The RPU is a wearable computer in the form of a necklace, neck ribbon, collar or other flat, flexible article that may be worn under clothing to hide it from view. The close proximity of the earpiece to the RPU, combined with the large antenna aperture area available in this RPU form, enables the use of radar technology to implement a two-way wireless link between the earpiece and RPU, and also allows earpiece operating power to be beamed from the RPU. The resulting size and cost reductions in both the earpiece and RPU allow the manufacture of disposable hearing aids and, when the RPU is equipped with secondary wireless link circuitry, cellular telephones and pagers.

Abstract: A micro-microphone, for attachment to the clothing or directly to the body of a user, has a housing with a housing mantle, an end plate connected to a first end of the housing mantle, and a bottom plate connected to the second end of the housing mantle. The housing mantle has one or more openings, each covered by a membrane positioned external to the housing mantle. The housing and the membranes thus define an inner hollow space inside the housing. A flaccid diaphragm is connected externally to a portion of the housing and encloses together with the portion of the housing a compensation chamber. The flaccid diaphragm seals the compensation chamber moisture-tightly. A component of high acoustic impedance connects the inner hollow space inside the housing to the compensation chamber. Pressure compensation is thus realized while moisture is excluded from the interior of the microphone.
