Each of the groups is configured to produce a different sound field representative of an audio signal and each of the groups comprise a different set of ... 08/16/07 - 20070189566 - Speaker apparatus A speaker apparatus includes a speaker, a tubular duct extended in order to make the sound generated in the inside of the cabinet of the speaker get to the vicinity of the listener's ears and a support mechanism that rotatably supports the tubular duct in order to bring the front ... 06/28/07 - 20070147645 - Loudspeaker system A loudspeaker unit (2) of a loudspeaker system (1) is fitted to a cabinet (4). An absorbent (3) is disposed in a hollow chamber (R) inside the cabinet (4) and absorbs a gas inside the hollow chamber (R). A phase inverting mechanism (8) inverts the phase by resonating with a ... 05/31/07 - 20070121982 - Electret assembly for a microphone having a backplate with improved charge stability The present invention relates to a microphone that includes a housing and a diaphragm and backplate located with the housing. The housing has a sound port for receiving the sound. The diaphragm undergoes movement relative to the backplate, which it opposes, in response to the incoming sound. The backplate has ... 05/24/07 - 20070116313 - Electro-acoustic sound diffuser Electro-acoustic Sound Diffuser in the form of a loudspeaker fitted with at least one driver powered by means of acceptable input signal; in proximity to at least one rotatable baffle which bear perforations and artwork; driven by an electric motor; means to control motor, for the purpose of modifying, altering, ... 07/20/06 - 20060159299 - Wide directionality speaker system, and cover attaching construction for plannar direct-mounted implements A wide dispersion speaker system 1 comprises a cone type speaker unit 2, and a restricting element 10A. The restricting element 10A is provided with a center hole 11 at a center section thereof, and a peripheral hole 12 located outward relative to the center hole 11. The restricting element ... 07/06/06 - 20060147076 - Electrodynamic acoustic transducer The invention relates to an acoustic transducer generating a sound radiation by compression and expansion of an air mass situated between a mobile membrane and a fixed surface or between two mobile membranes. The present invention concerns a transducer or acoustic loudspeaker of electrodynamic type designed to emit sound waves ... 12/01/05 - 20050265570 - Method to generate a plane acoustic wave front, a plane wave channel, a loudspeaker construction and a linear loudspeaker array A method and a loudspeaker construction (10), in which loudspeaker construction spherical acoustic wave fronts emitted by the diaphragms (12) of speaker elements (11) are transformed into a uniform, planar acoustic wave front. The loudspeaker construction (10) comprises a plane wave channel (20), in the surface (26) of which plane ... 08/04/05 - 20050169494 - Thermal chimney equipped audio speaker cabinet A thermally conductive chimney tube extends through a loudspeaker cabinet that encloses a volume of air heated by a speaker driver. The open ends of the chimney are outside the cabinet. A column of air within the chimney is in contact with the external ambient air, but sealed off from ... 07/28/05 - 20050163334 - Speaker with externally mounted acoustic extension A speaker comprises an enclosure with at least one wall; and an acoustic driver mounted in an interior of the enclosure and being attached to a front wall of the enclosure. An acoustic extension is mounted to the enclosure and is external of the enclosure. The acoustic extension is operatively ... 06/09/05 - 20050123162 - Externally ported loudspeaker enclosure An externally ported speaker enclosure includes a primary enclosure having a port or opening. The primary enclosure may continuously vary from a first dimension to a dimension of the port or opening. Alternatively, a duct or tube may extend from, and external to, the primary enclosure. The duct or tube ... ### FreshPatents.com Support |
