Abstract

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.

First claim

What is claimed is:

1. A coaxial speaker comprising:
a frame;
a plurality of magnetic components disposed within a recess of the frame, wherein a first accommodating space and a second accommodating space are formed by the plurality of magnetic components, wherein the first accommodating space comprises a first ring shape and the second accommodating space comprises a second ring shape, wherein a height of the second ring shape is greater than a height of the first ring shape;
a first speaker assembly comprising:
a first diaphragm operably coupled to the frame, where the first diaphragm comprises a first structure protruding toward the first accommodating space; and
a first voice coil disposed in the first accommodating space and operably coupled to the first structure; and
a second speaker assembly comprising:
a second diaphragm comprising a second structure protruding toward the second accommodating space; and
a second voice coil disposed in the second accommodating space and operably coupled to the second structure.

2. The coaxial speaker of claim 1 , wherein the coaxial speaker comprises a plurality of vent holes for venting the first accommodating space.

3. The coaxial speaker of claim 2 , wherein the coaxial speaker comprises an element disposed on the frame, and wherein the element is operable to tune the plurality of vent holes.

4. The coaxial speaker of claim 1 , wherein the coaxial speaker comprises a plurality of vent holes for venting the second accommodating space.

5. The coaxial speaker of claim 4 , wherein the coaxial speaker comprises an element disposed on the frame, and wherein the element is operable to tune the plurality of vent holes.

6. The coaxial speaker of claim 1 , wherein the first diaphragm and the second diaphragm are located in a same plane.

7. The coaxial speaker of claim 1 , wherein the first diaphragm is formed in a ring shape.

8. The coaxial speaker of claim 1 , wherein the second diaphragm is formed in a circular shape.

9. The coaxial speaker of claim 1 , wherein the plurality of magnetic components comprise a ring magnet.

10. The coaxial speaker of claim 1 , wherein the plurality of magnetic components comprise a magnet cup.

11. A speaker, comprising:
a casing comprising a dividing wall between a first sound chamber and a second sound chamber, wherein the first sound chamber and the second sound chamber are independent of each other, wherein the first sound chamber comprises a first ring shape and the second sound chamber comprises a second ring shape, wherein a height of the second ring shape is greater than a height of the first ring shape;
a first diaphragm disposed in the first sound chamber; and
a second diaphragm disposed in the second sound chamber, wherein a vibration frequency of the second diaphragm is higher than a vibration frequency of the first diaphragm.

12. The speaker of claim 11 , wherein the first sound chamber surrounds the second sound chamber.

13. The speaker of claim 11 , comprising a first voice coil, a second voice coil and a magnetic component, wherein the first voice coil is connected to the first diaphragm, the second voice coil is connected to the second diaphragm, the magnetic component is disposed in the casing and corresponds to the first voice coil and the second voice coil.

14. The speaker of claim 13 , wherein the dividing wall is operably coupled to the magnetic component.

15. The speaker according to claim 13 , wherein the magnetic component comprises a first magnetic conductive component, a second magnetic conductive component and a magnet, and wherein the first magnetic conductive component and the second magnetic conductive component are respectively connected to opposite sides of the magnet.

16. The speaker of claim 13 , wherein the magnetic component comprises a ring magnet.

17. The speaker of claim 13 , wherein the magnetic component comprises a magnet cup.

18. The speaker of claim 11 , wherein the casing comprises a plurality of venting holes, and wherein the venting holes respectively communicate with the first sound chamber and the second sound chamber.

19. The speaker of claim 16 , wherein the speaker comprises a plurality of dampers covering the venting holes.

20. The speaker of claim 11 , wherein the first diaphragm and the second diaphragm do not overlap each other in an axial direction of the speaker.
