Electrical Audio Signal Processing Systems And Devices > Electro-acoustic Audio Transducer Electro-acoustic Audio TransducerElectro-acoustic Audio Transducer patent applications listed are from June 2005 to current and include Date, Patent Application Number, Patent Title, Patent Abstract summary and are linked to the corresponding patent application page.11/15/07 - 20070263885 - Headset with integral hook A monaural headset (one speaker) having a hook structure for holding the headset on the ear of a wearer, with the hook structure able to be stored on the headset housing or in a channel feature of the headset housing, when the headset is not in use. ... 10/04/07 - 20070230719 - Efficient production of mechanical sound vibration An efficient method and apparatus for converting audio signals into mechanical vibrations is disclosed, the apparatus comprising a simple transducer. The transducer forms a dynamic magnetic field in response to an electronic signal. The dynamic field causes a mass positioned within the field to vibrate. When the mass is contacted ... 08/30/07 - 20070201708 - Method and apparatus for lipsync measurement and correction A method and apparatus for synchronizing audio and video portions of a media program signal is disclosed. The method comprises the steps of detecting an audio event in the audio portion of the media program signal, measuring the timing interval from the audio event to a subsequent video synchronization pulse ... 08/30/07 - 20070201707 - Acoustic effecter There is provided an acoustic effecter capable of compensating deterioration of an audio source signal in a transmission path and obtaining an audio having an emphasized transient response. The acoustic effecter superimposes reflection energy generated by impedance mismatch of the transmission path on the acoustic signal to be transmitted or ... 06/07/07 - 20070127744 - Acoustical receiver housing for hearing aids An acoustic receiver comprises means for converting an input audio signal into an acoustic signal. The receiver has a housing having a plurality of sides that surround the converting means. One of the sides include an output port for broadcasting the acoustic signal. A jacket fits around the housing and ... 02/22/07 - 20070041594 - Recording system and recording method A recording system is equipped with a pre-processing device which serves as an image recording unit for recording an image on sound paper based on image data, and a post-processing device which serves as a sound data recording unit for recording sound data related to the image data on the ... 02/15/07 - 20070036369 - Speaker cover A cover for a speaker device having a sound producing portion and a structure for supporting the sound producing portion, the cover includes an opening and an internal cavity therein for receiving and enclosing the speaker device, a first portion capable of passing produced sound therethrough, wherein the first portion ... 01/04/07 - 20070003080 - Speaker apparatus A speaker apparatus includes: a frame that has a diaphragm at a front side thereof; and a magnetic circuit that is disposed at a rear side of the frame so as to drive the diaphragm. The magnetic circuit includes a magnet having a polygonal outer profile coaxially positioned with the ... 12/07/06 - 20060274907 - Speaker device and manufacturing method thereof A speaker device includes a terminal member, a voice coil bobbin, and a connecting member mounted on the voice coil bobbin. The connecting member has a terminal mounting part. A pair of claw part and hook-shaped projecting part is provided on an upper end portion of the terminal mounting part, ... 10/26/06 - 20060239477 - Microphone orientation and size in a speakerphone In various embodiments, a speakerphone may comprise multiple (e.g., 16) microphones placed in a circular array around a central speaker. The microphones may be mounted vertically in the speakerphone with their respective diaphragms substantially parallel to the top surface of the speakerphone. The centrally mounted speaker may be coupled to ... 10/27/05 - 20050238187 - Loudspeaker with inverted cone An electrodynamic loudspeaker comprising a chassis (2), a movable body (4) flexibly connected to the chassis and having a three-dimensional diaphragm (8) with a base part (8b) and a top part (8a) which is wider than the base part, and an electromagnetic actuator (6) for moving said body with respect ... 08/18/05 - 20050180588 - Transducer with deformable corner A transducer generates acoustic energy. The transducer is suitable for incorporation into any device that needs sound reproduction capability, including devices with generally rectangular geometries such as cell phones, PDAs, and portable gaming devices. The transducer includes a displaceable membrane with a deformable corner. The deformable corner may extend the ... 08/18/05 - 20050180587 - Equalizable active electroacoustic device for panels, and method of converting the panels and assembling the devices Electro-acoustic device, which installed in flat-top panels, partitions or facings existing in the market, be they of mineral fibre, plasterboard, plywood, etc., transforms them into planar and invisible radiators of high fidelity sound and spherical dispersion. Through its particular property of being equalisable for each type of panel by means ... ### FreshPatents.com Support - Terms & Conditions |
