Abstract

An acoustic receiver comprises means for converting an input audio signal into an acoustic signal. The receiver has a housing having a plurality of sides that surround the converting means. One of the sides include an output port for broadcasting the acoustic signal. A jacket fits around the housing and has sections for engaging the sides. The sections are generally flat. The jacket may also form a gap with a corresponding side surface of the housing. A printed circuit board can be located within the gap. The printed circuit board including electronics for processing said input audio signal.

Claims

1. An acoustic receiver, comprising:

means for converting an input audio signal into an acoustic signal;

a housing having a plurality of sides that surround said converting means, one of said sides including an output port for broadcasting said acoustic signal, a second of said sides having an end surface that includes an electrical connector assembly; and

a jacket having at least three sections for directly engaging at least three of said sides, one of said sides being said second of said sides, said three sections being generally flat and lying on respective ones of said sides, at least two mutually adjacent ones of said three sections contacting corresponding ones of said sides.

2. The acoustic receiver of claim 1, wherein said jacket is made of stainless steel.

3. The acoustic receiver of claim 1, wherein said jacket is made of a soft magnetic material.

4. The acoustic receiver of claim 1, wherein said jacket is made of a polymer.

5. The acoustic receiver of claim 1, wherein said jacket is primarily made of Kapton.

6. The acoustic receiver of claim 1, wherein said jacket is made of epoxy.

7. The acoustic receiver of claim 1, wherein said jacket includes silicone.

8. The acoustic receiver of claim 1, wherein said jacket is adapted to shield said converting means from the effects of electromagnetic interference.

9. The acoustic receiver of claim 1, wherein said converting means includes electromagnetic components and a diaphragm.

10. The acoustic receiver of claim 1, wherein said jacket is preconfigured to be press-fit directly onto said housing.

11. The acoustic receiver of claim 1, wherein said jacket is welded onto said housing.

12. The acoustic receiver of claim 1, wherein said jacket is adhered to said housing.

13. The acoustic receiver of claim 1, wherein said jacket includes a layer of acoustical dampening material.

14. The acoustic receiver of claim 13, wherein said acoustical dampening material is composed of a material including epoxy.

15. The acoustic receiver of claim 1, wherein said jacket is generally cylindrical in shape.

16. The acoustic receiver of claim 1, wherein said jacket has a generally trapezium shape.

17. The acoustic receiver of claim 1, wherein said jacket has a generally trapezium-shaped cross section.

18. The acoustic receiver of claim 1, wherein said jacket has a generally rectangular cross section.

19. An acoustic receiver, comprising:

means for converting an input audio signal into an acoustic signal;

a housing having six sides that surround said converting means, a first one of said sides including an output port for broadcasting said acoustic signal; and

and a jacket having a rectangular cross-section and sections for closely interfitting with four of said six sides, one of said four of said six sides being said first one of said sides, wherein said sections of said jacket directly engage corresponding ones of said four of said six sides and wherein said jacket is welded to at least two of said sides.

20. The acoustic receiver of claim 19, wherein said jacket is made of a soft magnetic material.

21. The acoustic receiver of claim 19, wherein said jacket is a polymer.

22. The acoustic receiver of claim 19, further including a dampening material between said jacket and said housing.

23. A transducer, comprising:

means for converting between an acoustic signal and an audio signal;

a housing surrounding said converting means, said housing having two ends and at least two sides;

an electrical connector coupled to an end surface of one of said ends; and

a jacket surrounding at least a portion of said housing including said one of said ends, at least two sections of said jacket being permanently affixed to said sides by spot welding.

24. The transducer of claim 23, wherein said jacket has a thickness of between about 0.05 mm and 0.3 mm.

25. The transducer of claim 23, wherein said jacket is press-fit onto said housing.

26. The transducer of claim 23, wherein said jacket contacts at least one of said ends of said housing directly or via said layer of acoustical dampening material.

27. The transducer of claim 23, wherein said jacket contacts said majority of said surface of at least said two mutually adjacent sides of said housing via said layer of acoustical dampening material, said acoustical dampening material being composed of a material including epoxy.

28. The transducer of claim 23, wherein said least two sections are permanently affixed to said sides by adhesive.

29. An acoustic receiver, comprising:

means for converting an input audio signal into an acoustic signal;

an output port for broadcasting said acoustic signal;

a housing having a plurality of sides that surround said converting means;

an electrical connector coupled to an end surface of a first of said sides; and

a jacket having at least three sections for directly engaging at least three of said sides including said first side, said three sections being generally flat and lying on respective ones of said sides, at least two mutually adjacent ones of said three sections contacting corresponding ones of said sides.

30. The acoustic receiver of claim 29, wherein said jacket includes a layer of acoustical dampening material.

31. The acoustic receiver of claim 29, wherein said jacket is press-fit onto said housing.

32. The acoustic receiver of claim 29, wherein at least two of said at least three sections are permanently affixed to respective ones of said sides by adhesive.

33. The acoustic receiver of claim 29, wherein at least two of said at least three sections are permanently affixed to respective ones of said sides by spot welding.

34. The acoustic receiver of claim 29, wherein said jacket has a generally rectangular cross section.
