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 location to decrease occlusion and a second 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.

Devices and methods for hearing

Embodiments of the present invention provide improved methods and apparatus suitable for use with hearing devices. A vapor deposition process can be used to make a retention structure having a shape profile corresponding to a tissue surface, such as a retention structure having a shape profile corresponding to one or more of an eardrum, the eardrum annulus, or a skin of the ear canal. The retention structure can be resilient and may comprise an anatomically accurate shape profile corresponding to a portion of the ear, such that the resilient retention structure provides mechanical stability for an output transducer assembly placed in the ear for an extended time. The output transducer may couple to the eardrum with direct mechanical coupling or acoustic coupling when retained in the ear canal with the retention structure.

Anatomically customized ear canal hearing apparatus

Embodiments of the present invent include a method of controlling unwanted vibration in a tympanic lens, wherein the tympanic lens comprises a perimeter platform connected to a microactuator through at least one biasing element, the method comprising the step of: damping the motion of the at least one biasing element. In embodiments of the invention, the at least one biasing element is a spring. In embodiments of the invention, the at least one bias spring is coated in a damping material.

Damping in contact hearing systems

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 a noisy environment. Noise cancellation of background sounds near the user can be provided.

Multifunction system and method for integrated hearing and communication with noise cancellation and feedback management

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.
