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.
