Abstract: Apparatus and methods are described herein that provide a vibratory device that can apply a vibratory signal to a portion of a head of a user such that the vibratory signal can be conducted via bone to a vestibular system of the user and cause a portion of the vestibular system to move in a manner equivalent to that of a therapeutically effective vibratory signal applied to an area overlaying a mastoid bone of the user. The vibratory device can be associated with frequencies less than 200 Hz. The vibratory device can be effective at treating a physiological condition associated with the vestibular system.

Abstract: An audio system for use in a passenger compartment of a vehicle. The system includes a front-driver side speaker unit and a front-passenger side speaker unit to cooperatively emit audio sound to the passenger compartment. The driver-side speaker unit includes a primary speaker and a secondary speaker to produce sound in cooperation with a primary speaker and a secondary speaker of the passenger-side speaker unit. An audio control system is configured to compensate for unbalancing of stereo images at front-driver/passenger positions by controlling output from the secondary speakers based on output from the primary speakers.

Abstract: A loudspeaker has a cooling system in which a pole piece has a shorting ring made of non-magnetic conductive material that stabilizes magnetic field to reduce distortion of sound and a heat dissipation plate that couples to the shorting ring to facilitate efficient dissipation of heat. The heat generated by a voice coil of the loudspeaker is transmitted to the shorting ring and is conducted to the heat dissipation plate which acts as a heat sink to allow the heat dissipation. A multiplicity of shorting rings may be provided to further reduce impedance modulation, each of which is coupled to the heat dissipation plate. The heat dissipation plate has a gap in an axial direction of the loudspeaker to prevent an electric current in the shorting ring from flowing through the heat dissipation plate.

Abstract: A vehicle overhead audio system, an electromagnetic transducer assembly for use therein and a computer system programmed with a graphic software control for changing the audio system's signal level and delay are provided where a headliner of the vehicle is a loudspeaker of the system thereby replacing many other loudspeakers and being invisible to the occupants. The headliner is driven in multiple zones that effect proper imaging for all occupants. Supplemental high frequency and subwoofer speakers and signal processing circuitry are included in one aspect of the invention.

Abstract: A loudspeaker that incorporates features for improvements in performance, and quality while reducing component and manufacturing costs. One embodiment details a plastic frame with integrally molded spider. Another embodiment details a spider molded with individual legs that provides better control of the restorative force characteristic. The spider may also incorporate more than one plane of lateral stiffness to improve the loudspeakers tendency for voice coil rocking. An additional embodiment details a frame with generic mounting edge that mates with a secondary mounting flange that includes product specific requirements. The frame and mounting flange are separated by an outer section of the diaphragm suspension annulus that serves as vibration isolation. An additional outer section of the annulus can serve as a gasket to the mounting structure.
