Publication number: 20080049959Abstract: An earphone including a case, a case extension unit, a plate, a cover, a first speaker and a second speaker is provided. The first speaker is disposed on a supporting portion of the plate and is disposed on a first plane different from a second plane where the second speaker is located. A distance exits in the position of the first speaker and the position of the second speaker corresponding to a direction of the sound from the earphone to the user who wears the earphone. The distance variation can make the sound field have more special effects and have better frequency response in some frequency domain. The distance variation can also avoid the interference of different sound fields generated by the speakers inside the earphone, and thus improves the performance of the whole sound field.Type: ApplicationFiled: December 13, 2006Publication date: February 28, 2008Applicant: COTRON CORPORATIONInventor: Bill Yang

Patent number: 7289641Abstract: A multiple channel earphone is provided with an external tube disposed on the earphone main body. The earphone includes a case, a case extension unit, and a cover. A main sound field is formed in an interior chamber enclosed by the case, the case extension unit and the cover. By adjusting the space in the external tube, the spatial effect of the sound field is significantly increased. The proposed multiple channel earphone selectively has a mechanism for sound field balancing by the sounds generated from these two sub-speakers spaced apart from each other for better sound quality. The sound field of the proposed multiple channel earphone can also be spaced apart into two physically separated sound fields by disposing an external chamber on the earphone main body.Type: GrantFiled: March 17, 2005Date of Patent: October 30, 2007Assignee: Cotron CorporationInventor: Bill Yang

Patent number: 6427018Abstract: An ear mounted earphone includes a speaker housing for positioning a speaker at the entrance to the auditory canal of an ear of a user. An elongate boom extends from the speaker housing and through a sleeve at one end of an earpiece so that the boom may be moved longitudinally and rotationally within the sleeve for adjustment purposes and will be frictionally held in adjusted position by the sleeve during use. A microphone arm with microphone may be rotatably mounted on the speaker housing to provide a microphone when the earphones are used with a communication system. The rotatability of the microphone arm allowing the same earphone and microphone arm to be adjusted for use with either the right or left ear of a user. An earpiece may be conveniently integrally molded as a single piece with a slit formed therein intermediate its length so the wire to the speaker and microphone can be positioned within the earpiece. The speaker may be waterproofed by a thin waterproof material such as mylar.Type: GrantFiled: July 18, 1997Date of Patent: July 30, 2002Assignee: Cotron CorporationInventor: Shawn P. Keliiliki

Patent number: 6097827Abstract: An adjustable earphone with a microphone has a hook, a speaker, and a microphone, in which the hook is used for comfortably mounting the earphone on a user's ear. The speaker is mounted in a speaker chamber that connects to the hook by an outrigger wherein the speaker can be firmly fixed on the user's exterior acoustic meatus. The microphone is mounted in a microphone chamber that connects to the hook by a boom, and the microphone chamber can be fixed near the user's mouth. A speaker signal-wire used for transmitting the signal extends from the speaker chamber, passes through the hook, and then couples to the audio signal manager. A microphone signal-wire used for transmitting the signals extends from the microphone chamber, passes by the boom, and then couples to the audio signal manager.Type: GrantFiled: February 16, 1999Date of Patent: August 1, 2000Assignee: Cotron CorporationInventor: Bill Yang

Patent number: 6069964Abstract: The main components of an earphone-microphone-earmuff assembly are an earphone, a microphone and an earmuff. Besides using the assembly as a whole, each component can be independently used as well. The assembly has several pairs including a mounting cap, an earphone, an earmuff, and each part has its own mounting structure or structures for interconnection. In operation, the mounting cap and the earphone can be assembled together just for listening. Alternatively, the mounting cap and the earmuff can be assembled together just for ear warming or noise shielding. However, the mounting cap, the earmuff and the earphone can all be put together for hearing, ear warming and noise shielding. Furthermore, a microphone can also be installed on the earphone for easy communication.Type: GrantFiled: July 14, 1998Date of Patent: May 30, 2000Assignee: Cotron CorporationInventor: Bill Yang

Patent number: 6047076Abstract: An earphone-microphone set that has a pair of adjustable ear braces. The earphone-microphone set includes an earphone housing for enclosing the earphone. There is a shallow groove around the outer edge of the housing and a cable latch positioned vertically at each end of the groove. A hole is also drilled beside each of the cable latch. A microphone capable of rotating is attached to the earphone housing. One end of a signal transmission cable is connected to the earphone. The cable comes out from the edge of the earphone housing around its mid-section. The other end of the cable is connected to a plug. An upper ear-brace-adjusting pin and a lower ear-brace-adjusting pin are inserted into the respective upper circular hole and the lower circular hole beside the cable latches. The upper and the lower ear-brace-adjusting pin also passes through an upper ear brace and a lower ear brace so that each ear brace can slide up or down independently.Type: GrantFiled: May 17, 1999Date of Patent: April 4, 2000Assignee: Cotron CorporationInventor: Bill Yang
