A bone conduction hearing aid device comprising a vibrator configured to vibrate in response to sound signals received by the device. The device further comprises a housing mass forming a housing for one or more operational components of the device, wherein the housing mass is attached to the vibrator so as to move in response to the vibration. The device also comprises a coupling configured to attach the device to a recipient so as to deliver the generated mechanical to the recipient's skull.

Bone conduction device having an integrated housing and vibrator mass

A transcutaneous bone conduction system comprising a bone conduction device configured to vibrate in response to received sound. The system also comprises a totally implantable support apparatus positionable under a recipient's skin, comprising: a fixture configured to be implanted in the skull, and a substantially rigid cradle. The cradle has opposing, spaced plates connected by a bridge member, wherein a first of the plates is configured to be secured to the fixture and wherein the space between the plates is sufficient to receive the bone conduction device, and wherein the plates are configured to retain the bone conduction device against the skin proximate to the first plate.

Transcutaneous bone conduction system

A vibrator for generating vibrations in a bone conducting hearing device, i.e. a hearing device of the type in which the sound information is mechanically transmitted via the skull bone directly to the inner ear of a person. The vibratory movements are provided by a piezo-electric or magneto-elastic element arranged to transfer the vibrations via the skull bone from the area behind the outer ear to the inner ear. The piezo-electric or magneto-elastic element is arranged to be at least partially implanted in a surgically drilled hole directly into the mastoid bone behind the outer ear so that the vibrations are transferred directly from the element to the bone and transferred in the skull bone to the inner ear. The element is encapsulated with a bone integrating material, such as titanium or various biocompatible ceramic materials or coatings and is disc shaped and acts with a radial expansion upon electrical stimulation so that longitudinal sound waves are induced into the skull bone.
