Patent ID: 6855104

Claim:
An implantable, electromagnetic hearing aid transducer, comprising: a static transducer part including, a transducer housing hermetically sealed on all sides, and a ring coil arrangement fixedly mounted in the transducer housing; a dynamic part, adapted to be coupled to a body part of an implant wearer, including, at least one connecting element forming a movable, mechanical connection relative to the static transducer part, and a permanent magnet arrangement which interacts with the ring coil arrangement to vibrate in the direction of an axis of the ring coil arrangement, wherein the at least one connecting element is a flexible membrane which is composed at least partially of a viscous material, said flexible membrane functioning as an attenuation connecting element and forming part of the wall of the hermetically sealed transducer housing and having mechanical properties which enable a member to be used to select the specifically set frequency response of the implantable transducer.
