Patent number: 8634583Abstract: Hearing losses caused by deficiencies in a person's outer or middle ear may be compensated for by converting received sounds to vibrations and transmitting the vibrations to the skull bone (2). Bone-conduction hearing devices (27) may transmit such vibrations transcutaneously or percutaneously.

The present invention provides a device (1, 27, 37) and a method, which allow determination of the applied vibrational force with better precision than prior art devices and methods. This is achieved by placing an accelerometer (21) on the countermass (11) of the vibrator (1) that generates the vibration signal.Type: GrantFiled: May 25, 2011Date of Patent: January 21, 2014Assignee: Oticon Medical A/SInventor: Bengt Bern

The hearing aid device contains a receiver, a transducer of the sound or other acoustic signals into electrical current serving as a signal representing a sound, a pulsed irradiation source connected to the transducer for receiving the electrical current and for generating modulated pulsed irradiation in dependence from the electrical current, and preferably one or more optical fibers optically coupled to the exit of the pulsed irradiation source, wherein the optical path for conduction of irradiation within the device ends directly opposite a functional element of the natural vibration transduction pathway, e.g.Type: GrantFiled: February 1, 2010Date of Patent: December 3, 2013Assignee: Medizinische Hochschule HannoverInventors: Gentiana I.

Patent number: 8588447Abstract: Methods and apparatus for transmitting vibrations via an electronic and/or transducer assembly through a tooth or teeth are disclosed herein. The assembly may be attached, adhered, or otherwise embedded into or upon a removable oral appliance to form a hearing aid assembly. Such an oral appliance may be a custom-made device. The electronic and transducer assembly may receive incoming sounds either directly or through a receiver to process and amplify the signals and transmit the processed sounds via a vibrating transducer element coupled to a tooth or other bone structure, such as the maxillary, mandibular, or palatine bone structure.Type: GrantFiled: July 17, 2012Date of Patent: November 19, 2013Assignee: Sonitus Medical, Inc.Inventors: Amir A. Abolfathi, Vahid Saadat, Loc X. Phan

Patent number: 8577050Abstract: Embodiments provide improved bone conduction calibration. In one embodiment a bone conduction vibrator coupling member is provided with opposing surfaces configured to contact the housing of an earphone coupler about the opening of the housing and support the housing of a bone conduction vibrator above the opening of the earphone coupler housing. The coupling member has an inner wall defining an aperture extending through the coupling member that is configured to receive the vibrating member of the bone conduction vibrator and provide the vibrating member with access to the cavity of the earphone coupler. A calibration system includes a bone conduction vibrator coupling member positioned upon an earphone coupler. Methods for calibrating a bone conduction vibrator using such a calibration system are also provided.Type: GrantFiled: February 9, 2012Date of Patent: November 5, 2013Assignee: Audiology IncorporatedInventors: Robert H. Margolis, George Saly, Jonathan D. Birck

Publication number: 20130287239Abstract: An audio signal transmission device includes a first light source and a second light source configured to emit a first wavelength of light and a second wavelength of light, respectively. The first detector and the second detector are configured to receive the first wavelength or light and the second wavelength of light respectively. A transducer electrically coupled to the detectors is configured to vibrate at least one of an eardrum or ossicle in response to the first wavelength of light and the second wavelength of light. The first detector and second detector can be coupled to the transducer with opposite polarity, such that the transducer is configured to move with a first movement in response to the first wavelength and move with a second movement in response to the second wavelength, in which the second movement opposes the first movement.Type: ApplicationFiled: November 16, 2012Publication date: October 31, 2013Inventor: EarlLens Corporation
