ABSTRACT:
An implantable hearing aid transducer that compensates in situ for undesirable interfaces with a middle ear component. The transducer includes a housing, an actuator, a driver, and an actuator interface. According to one embodiment, the actuator interface is reshapeable in situ from a first shape to a second shape to permit movement of one of the actuator and the middle ear component in at least a first dimension to compensate for loading pressure. In this regard, the actuator interface may be gradually deformable to permit the movement of the transducer and/or the middle ear component, as well as, resistive to sudden movements of the actuator such that vibration at acoustic frequencies occurs between the actuator and the middle ear component.
