  • Publication number: 20110077453
    Abstract: Hearing systems for both hearing impaired and normal hearing subjects comprise an input transducer and a separate output transducer. The input transducer will include a light source for generating a light signal in response to either ambient sound or an external electronic sound signal. The output transducer will comprise a light-responsive transducer component which is adapted to receive light from the input transducer. The output transducer component will vibrate in response to the light input and produce vibrations in a component of a subject's hearing transduction pathway, such as the tympanic membrane, a bone in the ossicular chain, or directly on the cochlea, in order to produce neural signals representative of the original sound.

  • Publication number: 20100048982
    Abstract: A device to transmit an audio signal comprises at least one light source configured to transmit the audio signal with at least one wavelength of light. At least one detector is configured to detect the audio signal and generate at least one electrical signal in response to the at least one wavelength of light. A transducer is supported with and configured to vibrate at least one of an eardrum, an ossicle or a cochlea. Active circuitry is coupled to the transducer to drive the transducer in response to the at least one electrical signal, so as to provide the user with high quality sound.

  • Patent number: 7668325
    Abstract: A hearing system comprises a shell having an open inner chamber. An input transducer and a transmitter assembly are disposed in the open inner chamber. The transmitter has a frequency response bandwidth in a 6 kHz to 20 kHz range, and the open chamber has an end adjacent a patient's tympanic membrane with one or more openings that allow the ambient sound to pass through the chamber and directly reach the middle ear of the user.

  • Publication number: 20100034409
    Abstract: 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 of 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.

  • Publication number: 20090097681
    Abstract: Systems, devices and methods for communication include an ear canal microphone configured for placement in the ear canal to detect high frequency sound localization cues. An external microphone positioned away from the ear canal can detect low frequency sound, such that feedback can be substantially reduced. The canal microphone and the external microphone are coupled to a transducer, such that the user perceives sound from the external microphone and the canal microphone with high frequency localization cues and decreased feedback. Wireless circuitry can be configured to connect to many devices with a wireless protocol, such that the user can receive and transmit audio signals. A bone conduction sensor can detect near-end speech of the user for transmission with the wireless circuitry in noisy environment. Noise cancellation of background sounds near the user can improve the user's hearing of desired sounds.

  • Publication number: 20090092271
    Abstract: A hearing aid device for placement in an ear of a user includes an elongate support and a transducer. The elongate support has a proximal portion and a distal end, and the transducer is attached to the elongate support near the distal end. The support is adapted to position the transducer near an eardrum while the proximal portion is placed at the location near an ear canal opening. The elongate support is sized to minimize contact with the ear between the proximal portion and distal end. The elongate support permits sound waves to travel along the ear canal. In some embodiments, a microphone is positioned in the ear canal along the support, for example inside the support, to provide directionally dependent sound localization cues, and the transducer on the distal end of the elongate support comprises a coil assembly coupled to a magnet positioned on the tympanic membrane.

  • Patent number: 7421087
    Abstract: A hearing system for producing audio signals perceptible to an individual. The hearing system includes a transducer having a surface adapted to attach to a middle-ear acoustic member of the individual, wherein the transducer is responsive to variations in a magnetic field emitted by a transmitter to directly vibrate the acoustic member. The transmitter is supported within an ear canal of the individual. The transmitter has a coil and a core positioned so that the distal end of the core is located at a predetermined distance and orientation relative to the transducer.
