Abstract (en)
[origin: DE19840211C1] The transducer has a housing (14) that can be fixed at the implantation position and a mechanically stiff coupling element (20) movable with respect to the housing. A piezoelectric element (22) mounted in the housing can set the coupling element vibrating, and the vibrations are transferred to a middle ear ossicle or directly to the inner ear, after implantation of the transducer. An electromagnet arrangement (30,32) in the housing has a fixed and a vibrating component connected to the coupling element, so that the vibrations of the vibrating component are transferred to the coupling element. An Independent claim is also included for a partially or fully implantable hearing aid.
