<p>The application relates to an implantable actuator for Stimulation of a component of the hearing of a user, comprising a hermetically sealed gas-filled Chamber formed by a rigid housing (64) having a first opening closed by a first membrane (66 ) and a second opening closed by a second membrane (67), wherein the first membrane is for supporting an Output coupling System ( 24, 86), wherein the Output coupling System is to be coupled to said hearing component and is to be driven by a transducer of the actuator comprising a mobile transducer assembly, wherein the first membrane and the second membrane are fixedly coupled via a membrane coupling means (24, 72, 86) and wherein the second membrane is designed with regard to membrane area and compliance in a manner so as to prevent displacement of the first membrane (66 ) and the mobile transducer assembly relative to the housing due to deviations of the atmospheric pressure from a reference value.</p> |
