Optical electro-mechanical hearing devices with combined power and signal architectures

摘要

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.

主权项

1. A device to transmit an audio signal to a user, the device comprising:
a first light source configured to emit a first at least one wavelength of light; a second light source configured to emit a second at least one wavelength of light; a transducer assembly comprising at least one light responsive material configured to vibrate at least one of an eardrum, an ossicle, or a cochlea of the user; circuitry coupled to the first light source to emit first light pulses and to the second light source to emit second light pulses and wherein the circuitry is configured to adjust at least one of an energy or a timing of the first light pulses relative to the second light pulses to decrease noise of the audio signal transmitted to the user.
