Abstract

An earbud may include an acoustic driver. The acoustic driver may include a diaphragm and a magnetic circuit. A frame of the acoustic driver may be integrated with the earbud.

Claims

1. An in-ear earphone comprising:

an earbud comprising an acoustic driver having a diaphragm and a magnetic circuit, wherein a frame of the acoustic driver is integrated with the earbud.

2. The in-ear earphone of claim 1, wherein the acoustic driver is framed directly by the earbud.

3. The in-ear earphone of claim 1, wherein the acoustic driver is embedded in the earbud.

4. The in-ear earphone of claim 1, wherein the acoustic driver has no frame separate from the earbud.

5. The in-ear earphone of claim 1, further comprising:

a front cavity enclosure forming an outlet and a first port from the acoustic driver to an outside of the earbud.

6. The in-ear earphone of claim 5, further comprising:

an ear tip surrounding at least the front cavity enclosure.

7. The in-ear earphone of claim 6, wherein the ear tip has a second port mated to the first port to form a pressure equalization port from the acoustic driver to an outside of the ear tip.

8. The in-ear earphone of claim 5, further comprising:

a resistive mesh positioned over the first port.

9. The in-ear earphone of claim 1, further comprising:

a microphone.

10. The in-ear earphone of claim 1, wherein the frame of the acoustic driver integrated with the earbud maximizes a size of the diaphragm of the acoustic driver relative to a size of the earbud.

11. The in-ear earphone of claim 7, wherein the second port of the ear tip has a different length for a small tip ear tip than a medium tip ear tip.

12. The in-ear earphone of claim 1, further comprising:

a back cavity cap.

13. An earbud comprising:

an acoustic driver having a diaphragm and a magnetic circuit wherein a frame of the acoustic driver is integrated with the earbud.

14. The earbud of claim 13, wherein the acoustic driver is framed directly by the earbud.

15. The earbud of claim 13, wherein the acoustic driver is embedded in the earbud.

16. The earbud of claim 13, wherein the acoustic driver has no frame separate from the earbud.

17. The earbud of claim 13, further comprising:

a front cavity enclosure forming an outlet and a port from the acoustic driver to an outside of the earbud.

18. The earbud of claim 13, further comprising:

a back cavity cap.

19. The earbud of claim 17, wherein the port is a pressure equalization port from the acoustic driver to the outside of the earbud.

20. The earbud of claim 17, further comprising:

a resistive mesh positioned over the port.

21. The earbud of claim 17, further comprising:

a microphone.

22. The earbud of claim 13, wherein the frame of the acoustic driver integrated with the earbud maximizes a size of the diaphragm of the acoustic driver relative to a size of the earbud.

23. An ear tip for an in-ear earphone formed from a pliable material to surround at least a front cavity enclosure of an earbud wherein the earbud comprises an acoustic driver having a diaphragm and a magnetic circuit, and wherein a frame of the acoustic driver is integrated with the earbud.

24. The ear tip of claim 23, further comprising:

a first leg, a second leg, and a first port positioned between the first leg and the second leg to mate with a second port of the front cavity enclosure of the earbud.

25. The ear tip of claim 24, wherein the first port of the ear tip has a different length for a small tip ear tip than a medium tip ear tip.

26. The ear tip of claim 24, wherein the first port and the second port mate to form a pressure equalization port from the acoustic driver to an outside of the ear tip.
