Abstract
The invention relates to a transducer for a partially or fully implantable hearing aids for direct mechanical excitation of the middle or inner ear. The transducer is provided with a housing fixedly mounted at the implantation site and a coupling element moveable with respect to the housing for transmitting vibration to the middle ear ossicle or directly to the inner ear. The housing accommodates an electromagnetic component such as a coil which is fixed relative to the housing and a vibratory component such as a permanent magnet which is mechanically connected to the coupling element such that the vibration of the vibratory component is transferred to the coupling element.
