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 outer location to decrease occlusion and a second inner 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.
