Abstract: Moving armature receiver assemblies wherein a first U-shaped armature and a second U-shaped armature are configured for suppression of vibration of a housing structure along a longitudinal housing plane. The first armature has a fixed leg and a deflectable leg both extending parallelly to a first longitudinal armature plane and mechanically and magnetically interconnected through a first curved linkage portion. Likewise, the second armature has a fixed leg and a deflectable leg both extending parallelly to a second longitudinal armature plane and mechanically and magnetically interconnected through a second curved linkage portion. In some configurations, the deflectable legs of the first and second U-shaped armatures are configured for oppositely directed displacement along an orthogonal plane extending perpendicularly to the longitudinal housing plane so as suppress vibration of the housing structure in the orthogonal plane.

Abstract: A receiver or loudspeaker having a plurality of sound generators each having a housing and a sound output. An oblong channel is formed by a channel-forming element and parts of the housings. The sound outputs are positioned on one side of a middle of the channel and a outlet of the channel is positioned on the other side of the middle of the channel so that the channel has a length adapted to acoustically alter the sound. The use of the housings for forming the channels provides a more compact structure.

The receiver is disposed on a side opposite the side and outside the housing.

Abstract: The present invention relates to improvements in acoustical venting of hearing aid earmolds and to miniature loudspeakers with housing structures configured to support improved hearing aid venting. The miniature loudspeaker comprises a front chamber with first and second separate sound ports so as to allow the front chamber to form an integral part of the acoustical vent of the hearing aid earmold. Thus, while using the same opening in the hearing aid for both sound output and venting, sound from the outside of the hearing aid may be introduced into the users ear via the same opening.

Abstract: A hearing aid having two physically separate receivers, one for outputting low frequency (LF) acoustic sounds and another for outputting high frequency (HF) acoustic sounds. The LF receiver's output port is connected to a tube in which the HF receiver is inserted. The LF acoustic sounds either flow around the HF receiver, which include standoffs to space the HF receiver away from the inner tube wall, or through a channel in the HF receiver. At the output of the HF receiver, the LF and HF acoustic sounds are combined to form an acoustic signal that is transmitted to the ear canal. The LF receiver can be optimized for compliance, distortion, resonance frequency, and output. Its orientation is selected for reducing the overall size of the hearing aid. The HF receiver is smaller and placed far away from any microphone(s), reducing feedback effects, and may have a cylindrical or rectangular shape.
