Hybrid ring-radiator headphone driver
A system and method for a hybrid ring-radiator headphone driver, substantially as shown in and/or described in connection with at least one of the figures, as set forth more completely in the claims.
1. A headphone comprising:
one or more speakers, each speaker comprising:
a speaker frame comprising a stationary ring structure, wherein the stationary ring structure comprises a first ring and a second ring, wherein a height of the second ring is greater than a height of the first ring;
an inner magnet encircled by the stationary ring structure;
an inner coil operable to move according to the inner magnet;
a first diaphragm coupled to the inner coil;
a ring-shaped outer magnet that encircles the stationary ring structure;
an outer coil operable to move according to the outer magnet; and
a second diaphragm coupled to the outer coil.
2. The headphone of claim 1 , wherein the speaker frame comprises a vent hole operable to allow air flow between the inner magnet and the outer magnet.
3. The headphone of claim 2 , wherein the vent hole allows air flow for the inner coil.
4. The headphone of claim 1 , wherein the first ring defines a center space in which at least a portion of the inner magnet is positioned and in which at least a portion of the inner coil is positioned.
5. The headphone of claim 1 , wherein the speaker frame comprises a planar back side, at least a portion of which is directly behind a center radiator.
6. The headphone of claim 1 , wherein the speaker frame comprises a magnet cup in which the inner magnet is positioned, and wherein the speaker frame comprises a space into which the magnet cup is press fit.
7. The headphone of claim 1 , wherein the first diaphragm and the second diaphragm are different portions of a same diaphragm.
8. A headphone comprising:
a frame;
a center radiator comprising:
an inner magnet encircled by a stationary ring structure of the frame, wherein the stationary ring structure comprises a first ring and a second ring, wherein a height of the second ring is greater than a height of the first ring; and
an inner coil that moves in relation to the inner magnet;
a ring radiator comprising:
a ring-shaped outer magnet that encircles the stationary ring structure of the frame; and
an outer coil that moves in relation to the outer magnet; and
at least a first diaphragm portion coupled to the inner coil; and
at least a second diaphragm portion coupled to the outer coil.
9. The headphone of claim 8 , wherein the ring-shaped outer magnet comprises a slot in which the outer coil moves.
10. The headphone of claim 8 , wherein the ring-shaped outer magnet defines a central space bounded by an inner perimeter surface of the ring-shaped outer magnet, and the inner magnet extends entirely through the central space.
11. The headphone of claim 8 , wherein the inner magnet is thicker than the ring-shaped outer magnet.
12. The headphone of claim 8 , wherein at least one of the inner magnet and the ring-shaped outer magnet comprises a vent hole.
13. The headphone of claim 8 , wherein each of the inner magnet and the outer magnet comprises a center hole.
14. A headphone comprising:
a frame comprising a stationary ring structure, wherein the stationary ring structure comprises a first ring and a second ring, wherein a height of the second ring is greater than a height of the first ring;
a center radiator comprising:
an inner magnet; and
an inner coil that moves in relation to the inner magnet;
a ring radiator comprising:
a ring-shaped outer magnet that encircles the inner magnet; and
an outer coil that moves in relation to the outer magnet;
at least a first diaphragm portion coupled to the inner coil and coupled to the frame; and
at least a second diaphragm portion coupled to the outer coil and coupled to the frame.
15. The headphone of claim 14 , wherein the frame comprises a ring, the at least a first diaphragm portion is coupled to the ring, and the at least a second diaphragm portion is coupled to the ring.
16. The headphone of claim 14 , wherein the second diaphragm portion comprises two lobes, and an interface between the two lobes is positioned directly in front of the outer magnet.
17. The headphone of claim 14 , wherein each of the center radiator and the ring radiator comprises a same respective effective radiating area.
18. The headphone of claim 14 , wherein each of the center radiator and the ring radiator comprises a similar respective low frequency performance parameter.
19. The headphone of claim 14 , wherein the first diaphragm portion and the second diaphragm portion are different portions of a same diaphragm.
20. A headphone comprising:
at least one speaker comprising:
a frame comprising a stationary ring structure, wherein the stationary ring structure comprises a first ring and a second ring, wherein a height of the second ring is greater than a height of the first ring;
a magnetic component comprising an inner slot and an outer slot, wherein the inner slot and the outer slot are concentric rings;
an inner coil operable to move within the inner slot in relation to the magnetic component;
a first diaphragm coupled to the inner coil;
an outer coil operable to move within the outer slot in relation to the magnetic component; and
a second diaphragm coupled to the outer coil and the frame.
21. The headphone of claim 20 , wherein the frame comprises a ring, the first diaphragm is coupled to the ring, and the second diaphragm is coupled to the ring.
22. The headphone of claim 20 , wherein the magnetic component comprises at least one ring magnet.
23. The headphone of claim 20 , wherein the magnetic component comprises an inner magnet and an outer magnet.
24. The headphone of claim 20 , wherein the first diaphragm and the second diaphragm are different portions of a common diaphragm.
