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 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.
Claims5
A method of inductively transmitting an audio signal to a user, the method comprising:
- inductively coupling a first coil to a second coil, wherein the first coil is configured for placement in the ear canal of a user an the second coil is a part of a transducer configured for placement at least partially against the eardrum of the user;
- and
- driving a current through a third coil, wherein the second coil is electrically connected to the third coil.
