摘要:
An external component for a bone conduction hearing implant is described. An external housing is fixedly attached on the skin of a hearing implant patient over an implanted bone conduction hearing transducer. An electromagnetic drive coil arrangement is fixed within the external housing for conducting electrical current to develop electromagnetic drive signals. An attachment magnet arrangement is suspended within the external housing by a flexible spring arrangement and magnetically coupled to the drive coil arrangement and to a corresponding implant magnet arrangement within the implanted bone conduction transducer. The electromagnetic drive signals magnetically interact with the attachment magnet arrangement which reacts by vibrating on the spring arrangement and magnetically interacting with the implant magnet arrangement to generate a bone conduction vibration signal by the implanted bone conduction hearing transducer for perception by the patient as sound.
