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.

Claims

1. A receiver comprising:

a housing having an interior;

a diaphragm assembly disposed within the housing;

a motor assembly disposed within the housing;

a linkage assembly coupling the diaphragm assembly and the motor assembly; and

a support structure joined to the diaphragm or the motor assembly or to both the diaphragm and the motor assembly, the support structure including a cooperative surface portion engaging the housing to position and retain the joined diaphragm assembly or motor assembly within the interior.

2. The receiver of claim 1, the support structure joined to each of the diaphragm assembly and the motor assembly.

3. The receiver of claim 1, the support structure comprising a first support member joined to the diaphragm assembly and a second support member joined to the motor assembly, each of the first support member and the second support member comprising cooperative surface portions engaging the housing interior.

4. The receiver of claim 1, the cooperative surface portion comprising a first cooperative surface portion engaging the housing to position and retain the joined diaphragm or motor assembly in a first direction within with the interior and the a second cooperative surface portion engaging the housing to position and retain the joined diaphragm or motor assembly in a second direction within the interior.

5. The receiver of claim 1, the support structure comprising a flange, the cooperative surface portion formed on the flange.

6. The receiver of claim 1, the support structure comprising a flange, the cooperative surface portion comprising a first cooperative surface portion formed on the flange engaging the housing to position and retain the joined diaphragm or motor assembly in a first direction within with the interior and the a second cooperative surface portion formed on the flange engaging the housing to position and retain the joined diaphragm or motor assembly in a second direction within the interior.

7. The receiver of claim 1, wherein the support structure comprises a first flange extending from a surface of the support structure in a first direction and a second flange extending from the surface of the support structure in a second direction, the first flange engaging the housing and the second flange engaging the diaphragm assembly to position the joined diaphragm assembly or motor assembly in a first direction within the housing and to position the diaphragm assembly with respect to the motor assembly in the first direction.

8. The receiver of claim 1, wherein the support structure comprises a flange formed on periphery portion of the support structure and a post member formed internally of the periphery portion, the cooperative surface being formed on the flange to position the joined diaphragm assembly or motor assembly in a first direction and the post member engaging the housing to position the joined diaphragm assembly or motor assembly in a second direction.

9. The receiver of claim 1, the support structure comprising an aperture, the motor assembly being secured within the aperture.

10. The receiver of claim 1, the support structure comprising a first surface and a second surface spaced in a first direction relative to the first surface, the diaphragm assembly being joined to the first surface and the motor assembly being joined to the second surface.

11. The receiver of claim 9, the support structure comprising a flange extending from one of the first surface or the second surface, the cooperative surface being formed on the flange.

12. The receiver of claim 1, wherein the support structure comprises a partial cylinder having an inner surface and an outer surface and first and second end surfaces, the cooperative surface comprising a first cooperative surface formed on the outer surface to position the joined diaphragm assembly or motor assembly in a first direction and second cooperative surface formed on one of the first or second end surfaces to position the joined diaphragm assembly or motor assembly in a second direction.

13. The receiver of claim 1, disposed within a cellular phone, a digital camera, a personal digital assistant, a laptop computer, a wireless headset, an earphone or a tablet computer.

14. A method of producing a receiver, the receiver including a housing, a diaphragm assembly, a motor assembly and a linkage assembly joining the motor assembly and the diaphragm assembly, the method comprising:

providing a support structure;

joining the diaphragm assembly, the motor assembly or both the diaphragm assembly and the motor assembly to the support structure;

engaging a cooperative surface of the support structure with an interior surface of the housing to position and retain the joined diaphragm assembly or motor assembly within the housing.

16. The receiver of claim 14, the microphone being joined to the housing.

17. The receiver of claim 14, the microphone being disposed within the housing.

15. A receiver comprising:

a housing;

a diaphragm assembly and a motor assembly coupled by a linkage to the diaphragm assembly disposed within the housing; and

a signal processing circuit coupled to the motor assembly and an input audio signal, signal processing circuit driving the motor assembly responsive to the input audio signal to cause audible reproduction of the input audio signal by the diaphragm; and

a microphone coupled to the signal processing circuit, the microphone operable to receive acoustic signals external to the housing and to provide to the signal processing circuit a secondary input audio signal representative of the acoustic signals, the signal processing circuit driving the motor assembly responsive to the secondary input audio signal to cause audible reproduction of the acoustic signals in conjunction with the input audio signal by the diaphragm.

18. An earphone comprising:

a body having a first portion and a second portion defining a chamber;

a receiver disposed within the chamber;

a sound passage tube extending from the body and acoustically coupled to the chamber; and

a cord support member extending from the body providing a conduit passage for an electrical cord to the receiver.
