Electromagnetic Bone Conduction Hearing Device
First Claim
1. An external component for a hearing implant, the component comprising:
- an external housing containing an attachment magnet configured to magnetically connect with an implant magnet of an implanted signal transducer;
a pair of external electromagnetic drive coils within the external housing adjacent to the attachment magnet for conducting electrical current to develop magnetic drive signals through the skin to the signal transducer to generate responsive vibrations of the signal transducer for perception by the patient as sound;
wherein the drive coils are configured such that their respective magnetic drive signals have opposing magnetic directions.

Abstract
An external component for a hearing implant is described. An external housing contains an attachment magnet configured to magnetically connect with an implant magnet of an implanted signal transducer. A pair of external electromagnetic drive coils within the external housing are adjacent to the attachment magnet for conducting electrical current to develop magnetic drive signals through the skin to the signal transducer to generate responsive vibrations of the signal transducer for perception by the patient as sound. The drive coils are configured such that their respective magnetic drive signals have opposing magnetic directions.
