An improved partially implantable hearing device has a high coercivity permanent target magnet mounted to the ossicular chain by METABOND adhesive and being driven by an air core driving coil optimally implanted in a contactless manner at a spacing of approximately 1 mm. therefrom. The drive coil responds to auditory vibrations sensed by an externally concealed unit which converts these signals to an electrical signal transmitted to an externally located antenna which transmits same to an internally mounted antenna electronically connected to the air core electromagnetic driving coil.
