Abstract
A passive transcutaneous bone conduction device configured to deliver externally-generated mechanical vibrations to a bone of a recipient's head, the device comprising: an implantable magnetic coupler configured to be rigidly attached to the bone; and an external vibrator including an actuator having a movable magnetic mass; wherein the movable magnetic mass and the magnetic coupler form a transcutaneous magnetic coupling sufficient to retain the vibrator against soft tissue covering the bone with sufficient force to facilitate delivery of mechanical vibrations from the vibrator to the bone.
