US Patent 7524278 Hearing aid system and transducer with hermetically sealed housing

A driver and sensor assembly that is hermetically sealed so that the assemblies may be fully implanted in a being. The assemblies employ a transducer that has a longitudinal axis and that vibrates or picks up vibration in a direction substantially transverse to its longitudinal axis. A sheath covers the transducer and is hermetically sealed to a housing. Leads from a sound processor are coupled to the housing and the entire assembly is hermetically sealed.
