Abstract: A bone conduction transducer suitable for use in a listening device, such as hearing aids, in-ear monitors, headphones, electronic hearing protection devices, and very small scale acoustic speakers, has an end mass assembly disposed within the housing. The end mass assembly is mounted to the acoustic assembly and operatively coupled to the motor assembly via a coupling assembly.

Abstract: A transducer system may include multiple transducers. The transducers may be mounted together and may include either the same transducer type or different transducer types, depending on the desired applications. The transducers may be receivers which are aligned and joined. A coupling circuit may be provided and coupled to one or both of the transducers.

Abstract: A receiver includes a housing having an interior, a diaphragm assembly disposed within the housing, a motor assembly disposed within the housing and a linkage assembly coupling the diaphragm assembly and the motor assembly. A support structure joined to the diaphragm or the motor assembly or to both the diaphragm and the motor assembly. The support structure includes a cooperative surface portion engaging the housing to position and retain the joined diaphragm assembly or motor assembly within the interior. A corresponding method of manufacture employs a support structure for positioning components of the receiver in the housing. A receiver may also incorporate a microphone to through pass acoustic signals external to the receiver housing through the receiver. An earphone assembly may incorporate a receiver as described.
