An implantable hearing aid transducer is easily mounted within a middle ear region by the force of attraction between two permanent magnets. The transducer is preferably coupled to one of the magnets prior to implantation. The transducer is coupled to the magnet by an adhesive, by a transducer case containing both the magnet and the transducer, or by being encompassed by the magnet.
