Phi-based enclosure for speaker systems
View Patent ↗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.
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.
