Abstract

A transducer suspension element is presented. The transducer suspension element includes a suspension member having a body, the body having a main portion, a first portion extending from the main portion and continuing to an outer edge, and a second portion extending from the main portion and continuing to an inner edge. At least one conductor is disposed within or on the suspension member body, the at least one conductor extending at least within a section of the first portion and within a section of the second portion of the suspension member, and wherein a length of the at least one conductor of the suspension member is greater than a minimal distance from the inner edge to the outer edge across the suspension member.

First claim

What is claimed is:

1. A transducer suspension element comprising:
a suspension member having a body, the body having a main portion, a first portion extending from the main portion and continuing to an outer edge, and the body having a second portion extending from the main portion and continuing to an inner edge; and
at least one conductor within the suspension member body, the at least one conductor extending within the first portion, the main portion, and the second portion of the suspension member, and wherein a length of the at least one conductor within the suspension member body is greater than a minimal distance from the inner edge to the outer edge across the suspension member, wherein a path of the at least one conductor within the suspension member at least partially traverses a circumference of the suspension member.

2. The transducer suspension element of claim 1 wherein the at least one conductor comprises tinsel wire.

3. The transducer suspension element of claim 1 wherein the at least one conductor has a wave shape within at least a portion of the suspension member.

4. The transducer suspension element of claim 1 wherein the at least one conductor has a coiled shape within at least a portion of the suspension member.

5. The transducer suspension element of claim 1 wherein the suspension element further comprises at least one skin layer.

6. The transducer suspension element of claim 5 wherein the at least one skin layer surrounds a foam material, and the at least one conductor is embedded within the foam material.

7. The transducer suspension element of claim 1 wherein at least one of the first portion and the second portion have a generally tapered shape.

8. The transducer suspension element of claim 1 wherein the at least one conductor has one of: a two dimensional path and a three-dimensional path within at least a portion of the suspension member.

9. A transducer suspension element comprising:
a suspension member having a body, the body having a main portion, a first portion extending from the main portion and continuing to an outer edge, and the body having a second portion extending from the main portion and continuing to an inner edge; and
at least one conductor disposed along at least a portion of an outside surface of the suspension member, the at least one conductor having a first end and a second end wherein the first end extends within at least a section of the first portion, wherein the second end extends within at least a section of the second portion, and wherein the at least one conductor extends along an outside surface of at least a portion of the main body, wherein a length of the at least one conductor is greater than a minimal distance from the inner edge to the outer edge across the suspension member, and wherein at least one of the first portion and the second portion have a generally tapered shape.

10. The transducer suspension element of claim 9 wherein a path of the at least one conductor within the suspension member is substantially radial.

11. The transducer suspension element of claim 9 wherein a path of the at least one conductor within the suspension member at least partially traverses a circumference of the suspension member.

12. The transducer suspension element of claim 9 wherein the at least one conductor comprises tinsel wire.

13. The transducer suspension element of claim 9 wherein the at least one conductor has a wave shape within at least a portion of the suspension member.

14. The transducer suspension element of claim 9 wherein the at least one conductor has a coiled shape within at least a portion of the suspension member.

15. The transducer suspension element of claim 9 wherein the suspension element further comprises at least one skin layer.

16. The transducer suspension element of claim 9 wherein the at least one skin layer surrounds a foam material.

17. The transducer suspension element of claim 9 wherein the at least one conductor has one of: a two dimensional path and a three-dimensional path within at least a portion of the suspension member.

18. A transducer suspension element comprising:
a suspension member having a body, the body having a main portion, a first portion extending from the main portion and continuing to an outer edge, and the body having a second portion extending from the main portion and continuing to an inner edge; and
at least one conductor disposed within the suspension member body along an inside surface

of the suspension member, the at least one conductor extending within the first portion, the main portion, and the second portion of the suspension member, and wherein a length of the at least one conductor within the suspension member body is greater than a minimal distance from the inner edge to the outer edge across the suspension member, wherein the first portion has a generally tapered shape.

19. The transducer suspension element of claim 18 wherein a path of the at least one conductor within the suspension member is substantially radial.

20. The transducer suspension element of claim 18 wherein a path of the at least one conductor within the suspension member at least partially traverses a circumference of the suspension member.

21. The transducer suspension element of claim 18 wherein the at least one conductor comprises tinsel wire.

22. The transducer suspension element of claim 18 wherein the at least one conductor has a wave shape within at least a portion of the suspension member.

23. The transducer suspension element of claim 18 wherein the at least one conductor has a coiled shape within at least a portion of the suspension member.

24. The transducer suspension element of claim 18 wherein the suspension element further comprises at least one skin layer.

25. The transducer suspension element of claim 18 wherein the at least one skin layer surrounds a foam material, and the at least one conductor is embedded within the foam material.

26. The transducer suspension element of claim 18 wherein the second portion has a generally tapered shape.

27. The transducer suspension element of claim 18 wherein the at least one conductor has one of: a two dimensional path and a three-dimensional path within at least a portion of the suspension member.
