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 electrode 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: Contact hearing devices for use with a wearable communication apparatus are disclosed to provide the user with an open ear canal to hear ambient sound and sound from an audio signal. The disclosed devices and systems have an advantage of providing sound to user from the audio signal, in many embodiments without creating sound that can be perceived by others. The contact hearing device can also be used to amplify ambient sound to provide a hearing assistance to users with diminished hearing. The wearable information apparatus can be configured to couple wirelessly to the contact transducer assembly, such that the wearable information apparatus can be removed while the contact transducer assembly remains placed on the user.

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 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.
