Patent number: 8218803Abstract: In the case of a receiver facility to be fixed in the auditory canal, particularly for hearing devices with an external receiver, the receiver is to be mounted in the earmold in an acoustically advantageous fashion which guards against contaminations and is also easily exchangeable. Provision is thus made for a receiver facility with a longish receiver and a earmold, which has a borehole, into which the receiver is inserted. A tubular connector, which is more elastic than the receiver and the earmold, is used to accommodate for the most part the longitudinal extension of the receiver in a friction-locking fashion. The connector is for its part force-fitted into a borehole of the earmold in a friction-locking fashion. The receiver is thus elastically mounted and can be easily removed from the earmold together with the connector with the aid of a pin-like tool for replacement purposes.Type: GrantFiled: August 5, 2008Date of Patent: July 10, 2012Assignee: Siemens Medical Instruments Pte.

A branch following the edge of the cavum conchae transforms, above the antitragus, into a bent crosspiece traversing the cavum conchae and extending in the direction of the porous acusticus externus. The end section of the crosspiece lies in the upper section of the auditory canal and widens to accept the signal conductor (42).Type: GrantFiled: March 2, 2004Date of Patent: June 19, 2007Inventor: Erich Bayer

Patent number: 7079664Abstract: The present invention teaches a wireless ear-piece headset forming an antenna with the interior of a human ear, especially the ear canal. An antenna in operative connection with such interior of such human ear greatly improves reception and transmission of the device. The antenna may be comprised of a conductive plastic forming the lower body of the ear-piece headset, a sound tube projecting from the body or only a part thereof. The antenna may form an efficient capacitive connection with the body or may form a direct electrical connection. The wireless ear-piece headset comprises a headset body; a microphone, a transceiver, a receiver and a battery within the headset body, and a sound tube projecting from the headset body. A mini-speaker disposed within the headset body passes sound from the mini-speaker out and into the interior of a human ear.Type: GrantFiled: January 30, 2003Date of Patent: July 18, 2006Inventor: Shary Nassimi

Patent number: 7062059Abstract: A headset microphone boom that includes a hollow tubular member with a reflective interior surface. A light disperser is coupled to the hollow tubular member at one end and a light emitting device is coupled to the hollow tubular member at the other end. Light is transmitted from the light emitting device through the hollow tubular member to the light disperser. Sound waves are simultaneously transmitted from an acoustic port through the hollow tubular member to a microphone.Type: GrantFiled: June 25, 2004Date of Patent: June 13, 2006Assignee: Plantronics, IncInventor: James F. Bobisuthi

Patent number: 7054457Abstract: A hearing instrument and method of assembly are disclosed. The hearing instrument comprises an electronic assembly for providing received sound to the ear canal of a hearing instrument user. The electronic assembly is placed within a chamber in a housing sized to fit within the ear of the hearing instrument user. The chamber includes an internal guide channel and mounting surface for locating and positioning the electronic assembly. A volume encompassed within a hearing aid housing may be analyzed, such as with computer software, to identify a location within the chamber to position the electronic assembly, and then the electronic assembly may be incorporated into the housing using a guide channel and mounting surface of the housing for locating and positioning the electronic assembly in the identified location.Type: GrantFiled: August 13, 2002Date of Patent: May 30, 2006Assignee: Siemens Hearing Instruments, Inc.Inventor: Oleg Saltykov

Patent number: 7050599Abstract: A communications earpiece includes a member shaped to fit within an ear canal. The member has a passageway extending therethrough. There is a filter communicating with the passageway. The filter has a passageway extending therethrough and is aligned with the passageway in the member. The passageway in the filter has at least a portion which is narrower than the passageway in the member. Preferably the passageway in the filter has a first section and a second section. The second section is narrower than the first section and the passageway in the member. A method of attenuating acoustical signals in the communications earpiece is also provided. The earpiece has a member shaped to fit within an ear canal. The member has a passageway extending therethrough. The method comprises placing a restriction in the earpiece which is substantially narrower than the passageway and which communicates with the passageway.Type: GrantFiled: September 9, 2004Date of Patent: May 23, 2006Assignee: Custom Protect Ear Inc.Inventor: Orval Baskerville

Patent number: 6920228Abstract: A lightweight communications headset includes a headband adapted to be worn on user's head. A speaker housing is carried by the headband and defines an acoustic chamber. A speaker mounted within projects sound waves into the acoustic chamber. The headband carries a pair of earpieces which are positionable adjacent to the user's ears for delivering sound thereto. The acoustic chamber is coupled to earpieces through acoustic passages which transmit sound waves produced in the acoustic chamber to the earpieces. The earpieces preferably include removable in-ear inserts, which may be constructed for insertion into the auditory canals of the user's ears. Since the in-ear inserts are removable, the headset can readily be configured for a variety of applications.Type: GrantFiled: August 20, 2002Date of Patent: July 19, 2005Assignee: Otto Engineering, Inc.Inventors: Karl W. Redmer, John A. Towns, Gene H. Jones

Publication number: 20040125979Abstract: An earphone for use with portable communication devices (PCDs), particularly cellular phones, where the electro-magnetic (EM) radiation of the device is distanced from the head of the user, while acoustic waves are collected and brought through an acoustic tube to the ear of the user. The earphone may employ a coupler where the coupler contains a microphone and speaker acoustically insulated from each other. The coupler is positioned distant from both the ear of the user and the PCD. The coupler delivers acoustic waves to an acoustic tube for transmittal to the ear.Type: ApplicationFiled: February 6, 2003Publication date: July 1, 2004Inventors: Josef Elidan, Michael Mager
