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.

Abstract: A plastic fastener for securing moldings to frames in vehicles. The fastener includes minor slots formed in the fastener and adjacent to a coupling structure. The minor slots provide sufficient flexibility to allow the fastener to flex inward under pressure, thereby permitting the coupling structure to move between an engagement position and a retracted position. The fastener is pushed through an opening in the frame. The opening is sized such that the edges of the opening apply pressure to the fastener as it moves through the opening, thereby moving the coupling structure toward its retracted position. When the fastener completely in the opening, the pressure is relieved, and the coupling structure snaps back to its engagement position, thereby engaging the edges of the opening and securing the fastener thereto. The fastener may be removed from the opening by applying sufficient pressure to again move the coupling structure to its retracted position.
