Abstract: An implantable device is configured for placement in the eardrum to transmit an audio signal to a user. The device may be configured to improve transmission of an electromagnetic signal from an input assembly on a lateral side of an eardrum to an output assembly positioned on a medial side of the eardrum, for example, at least partially in the middle ear of the user. The output assembly may comprise a transducer or at least two electrodes configured to stimulate the cochlea, for example. The device may include an opening to transmit the light signal or an optic to transmit the light signal. Alternatively, the device may be configured to support a transducer of the output assembly with the eardrum when the device is implanted in the eardrum, such that the eardrum vibrates in response to the electromagnetic signal. The electromagnetic signal may include light energy.

Abstract: A device to transmit an audio signal to a user comprises a transducer and a support. The support is configured for placement on the eardrum to drive the eardrum. The transducer is coupled to the support at a first outer location to decrease occlusion and a second inner location to drive the eardrum. The transducer may comprise one or more of an electromagnetic balanced armature transducer, a piezoelectric transducer, a magnetostrictive transducer, a photostrictive transducer, or a coil and magnet. The device may find use with open canal hearing aids.

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.

Abstract: An output assembly is sized for placement in the middle and inner ear, such that removal of bone can be decreased. The output assembly may comprise at least one photo detector, a demultiplexer and an optical array sized to pass through an incision in the eardrum. An input transducer assembly is configured to transmit a multiplexed optical signal to the output assembly. The input assembly can be configured to transmit the multiplexed optical signal through the eardrum, such that tissue removal can be decreased and the device can be placed without removal of bone, for example. The multiplexed optical signal may comprise a pulse width modulated signal so as to decrease the effect of non-linearities of the light source and light detector and provide quality sound to the user.

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.

Abstract: A hearing device can allow a user to determine from side which a sound originates with bone conduction vibration of the cochlea and the user can also receive sound localization cues from the device, as feedback can be substantially inhibited with bone conduction vibration of the cochlea. An output transducer assembly can be positioned on a first side of the user to vibrate a first bone tissue near a first cochlea with a first amount of energy, such vibration of a second cochlea on a second side with a second amount of energy is attenuated substantially, for example at least about 6 db, such that the user can localize the sound to the first side. A microphone may be located on the first side and coupled to the output transducer assembly, such that the user localizes the sound to the first side detects sound localization cues.

Abstract: A transducer is configured to couple to the cochlear fluid so as to transmit sound with low amounts of energy, such that feed back to a microphone positioned in the ear canal is inhibited substantially. The cochlear fluid coupled hearing device can allow a user to determine from which side a sound originates with vibration of the cochlea and the user can also receive sound localization cues from the device, as feedback can be substantially inhibited. The transducer may be coupled to the cochlear fluid with a thin membrane disposed between the transducer and the cochlear fluid, for example with a fenestration in the cochlea. In some embodiments, a support coupled to the transducer directly contacts the fluid of the cochlea so as to couple the transducer to the cochlear fluid.

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 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.

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.
