Abstract

A speaker system with an enclosure having a spiral pathway is presented. The speaker system includes an electro-acoustic transducer that generates sounds according to an audio input. The speaker system also includes an enclosure having an interior pathway defined by a wall that is curved substantially as a spiral. The speaker system is configured such that the sound generated by the electro-acoustic transducer travels along at least a portion of the curved pathway before leaving the enclosure.

Claims (28)

1. A speaker system, comprising:

an electro-acoustic transducer having a diaphragm; and

an enclosure comprising a pathway defined by a curved wall that is curved substantially as a golden spiral, wherein the curved wall deviates sinusoidally from the golden spiral,

wherein the pathway has a first opening and a second opening, wherein the first opening is smaller than the second opening,

wherein the electro-acoustic transducer is positioned within the pathway closer to the first opening than the second opening such that sound produced by the electro-acoustic transducer travels through the pathway before leaving the enclosure via the second opening.

2. The speaker system of claim 1 , wherein a cross-section of the pathway expands as the pathway is further away from the first opening.

3. The speaker system of claim 1 , wherein the pathway has a round cross-section.

4. The speaker system of claim 1 , wherein the pathway has a convex polygonal cross-section.

5. The speaker system of claim 1 , wherein the enclosure comprises a material having an attenuation coefficient below 0.33.

6. The speaker system of claim 1 , wherein the enclosure comprises a material having an attenuation coefficient greater than 0.66.

7. The speaker system of claim 1 , wherein a portion of the curved wall deviates radially outward from the spiral.

8. The speaker system of claim 1 , wherein the electro-acoustic transducer is positioned so that the diaphragm is positioned within the pathway.

9. The speaker system of claim 1 , wherein the electro-acoustic transducer is positioned so that the diaphragm is substantially perpendicular to a cross-section of the pathway.

10. The speaker system of claim 1 , wherein the electro-acoustic transducer is positioned so that the diaphragm is substantially co-planar with a cross-section of the pathway.

11. A speaker system, comprising:

an electro-acoustic transducer having a diaphragm; and

an enclosure comprising a pathway that is curved substantially as a golden spiral, wherein the curved wall deviates sinusoidally from the golden spiral,

wherein the pathway has a first opening and a second opening, wherein the first opening is smaller than the second opening,

wherein the electro-acoustic transducer is positioned within the pathway closer to the first opening than the second opening such that sound produced by the electro-acoustic transducer travels through the pathway before leaving the enclosure via the second opening.

12. The speaker system of claim 11 , wherein the pathway has a round cross-section.

13. The speaker system of claim 11 , wherein the pathway has a convex polygonal cross-section.

14. The speaker system of claim 11 , wherein a portion of the curved pathway deviates radially outward from the golden spiral.

15. The speaker system of claim 14 , wherein the portion is near the second opening.

16. The speaker system of claim 11 , wherein the enclosure comprises a material having an attenuation coefficient below 0.33.

17. The speaker system of claim 11 , wherein the enclosure comprises a material having an attenuation coefficient greater than 0.66.

18. The speaker system of claim 11 , wherein the electro-acoustic transducer is positioned so that the diaphragm is positioned within the pathway.

19. The speaker system of claim 11 , wherein the electro-acoustic transducer is positioned so that the diaphragm is substantially co-planar with a cross-section of the pathway.

20. The speaker system of claim 11 , wherein the electro-acoustic transducer is positioned so that the diaphragm is substantially perpendicular to a cross-section of the pathway.
