Patent number: 8107663Abstract: A headset has a hollow housing having a front wall with at least one sound hole formed thereon, and a rear wall facing the front wall having a plurality of air holes formed thereon. A loudspeaker unit is disposed in the housing and adjacent to the sound hole. An adjustive component is rotatably mounted to the rear wall of the housing. The adjustive component has an adjustive switch outside the rear wall and a blocking slice against an inner surface of the rear wall and connected with the adjustive switch. The adjustive switch is capable of controlling the blocking slice to swing and halt repetitiously, for altering the number of the covered air holes when the adjustive switch is driven to rotate.Type: GrantFiled: April 24, 2009Date of Patent: January 31, 2012Assignee: Cheng Uei Precision Industry Co., Ltd.Inventor: You-Ruei Lin

Patent number: 8041067Abstract: An earphone structure including one or more composite chambers is described. Each of the composite chambers includes sub-speakers. The sounds generated by these sub-speakers are uniformly distributed in the composite chamber and a composite sound field is generated by these sub-speakers. The sound field generated by each of these sub-speakers can be adjusted by re-locating the position of the sub-speaker, for example, by re-locating the sub-speaker, or by re-locating the sub-speaker in different angles, to generate the composite sound field. The sound field generated by the main speaker and the composite sound field generated by these sub-speakers can form a spatial sound with very good quality. By using of its physical characteristics of locations of these sub-speakers, the sound generated by the earphone has an uniformly diffusion sound pressure and a surround effect, which allows a user of the earphone to enjoy a sound field similar to that in a theater.Type: GrantFiled: October 30, 2008Date of Patent: October 18, 2011Assignee: Cotron CorporationInventor: Bill Yang

Publication number: 20110216932Abstract: A headphone of convenient assembly and package includes a first earpiece and a second earpiece. The first earpiece has a tubular first casing and the first casing includes a first ear plug. The second earpiece has a tubular second casing and the second casing includes a second ear plug. The first casing has a clasping portion at an end opposite to the first ear plug. The second casing has a clasping recess at an end opposite to the second ear plug for receiving the clasping portion. Therefore, the first earpiece and the second earpiece can be assembled together into a tubular single piece, benefiting the first earpiece and the second earpiece for being packaged and carried, thus improving the convenience of the headphone.Type: ApplicationFiled: March 5, 2010Publication date: September 8, 2011Inventor: Hsien-Yu WU

Patent number: 8000486Abstract: Headsets (20, 50, 60, 71) provide surround sound and full 3 dimensional effects to a user to simulate the effects of direction and sound source. Advantages include: surround sound effect without the limitations of Head-Related Transfer Functions, and pinna effect customized to each user's ears; horn shape tube outlets (32) to create an efficient transmission of sound; ability to space the headset speakers (22, 24) away from the user's ear and to maintain sound quality by addition of a chamber (28) behind the speakers (22, 24), with the aid of tube sound guides (23, 25) and the horn shaped outlets; and, no need for electronic hardware to process the electrical signals to create desired effects as placement of the speakers creates the correct timing, and damping material (34) in the tubes between speakers creates a desired intensity drop. Head tracking capability is also provided.Type: GrantFiled: June 16, 2004Date of Patent: August 16, 2011Inventor: James G. Hildebrandt

Patent number: RE43939Abstract: A headset has an earcup with front opening adjacent to an annular cushion formed with a plurality of openings facing the inside of the earcup that acoustically couples the earcup volume to the cushion volume. A driver is seated inside the earcup with a microphone adjacent to the driver. Active noise reducing circuitry intercouples the driver and microphone. An acoustic load that may comprise a wire mesh resistive cover and/or air mass adjacent the microphone is constructed and arranged to reduce the effect of resonances in the earcup volume.
