Abstract

This disclosure includes several different features suitable for use in circumaural and supra-aural headphones designs. Designs that enhance user comfort and improve user control of the headphones are discussed. Various sensor configurations and electronic component positions are also discussed. User convenience features that include detachable cushions and automatically detecting the donning and doffing of headphones are also discussed.

First claim

What is claimed is:

1. Headphones, comprising:
a headband assembly; and
a first earpiece coupled to a first end of the headband assembly and a second earpiece coupled to a second end of the headband assembly, each of the first and second earpieces comprising an earpiece housing, an acoustic driver disposed within the earpiece housing and an earpiece cushion assembly coupled to the earpiece housing to cooperatively define a cavity sized to accommodate an ear of a user, the earpiece cushion assembly comprising:
an annular earpiece cushion; and
a support structure disposed between the annular earpiece cushion and the earpiece housing, the support structure comprising a plurality of cantilevered support members distributed along a periphery of the cavity and protruding laterally into the cavity towards a center region of the cavity.

2. The headphones as recited in claim 1 , wherein each of the cantilevered support members has a curved geometry that follows a curvature of a portion of the annular earpiece cushion.

3. The headphones as recited in claim 1 further comprising a cushion frame wherein the support structure is integrally formed with the cushion frame and the cushion frame is coupled directly to the earpiece housing.

4. The headphones as recited in claim 3 , wherein the support structure and the cushion frame cooperatively define an annular channel, the annular earpiece cushion being disposed within the annular channel.

5. The headphones as recited in claim 1 wherein each of the plurality of cantilevered support members is sized and shaped to allow the cantilevered support member to deflect independently from adjacent ones of the cantilevered support members when the headphones are worn by a user.

6. The headphones as recited in claim 1 wherein the annular earphone cushion comprises a foam cushion disposed within a protective cover.

7. Headphones, comprising:
a headband assembly; and
a first earpiece coupled to a first end of the headband assembly and a second earpiece coupled to a second end of the headband assembly, each of the first and second earpieces comprising an earpiece housing, an acoustic driver disposed within the earpiece housing and an earpiece cushion assembly coupled to the earpiece housing to cooperatively define a cavity sized to accommodate an ear of a user, the earpiece cushion assembly comprising:
an annular earpiece cushion;
a support structure disposed between the annular earpiece cushion and the earpiece housing, the support structure comprising cantilevered support members distributed along a periphery of the cavity and protruding into the cavity; and
a protective cover that wraps around both the annular earpiece cushion and at least a portion of the support structure.

8. The headphones as recited in claim 7 , wherein the protective cover comprises material selected from a group consisting of leather and textile material.

9. Headphones, comprising:
a headband assembly; and
a first earpiece coupled to a first end of the headband assembly and a second earpiece coupled to a second end of the headband assembly, each of the first and second earpieces comprising an earpiece housing, an acoustic driver disposed within the earpiece housing and an earpiece cushion assembly coupled to the earpiece housing to cooperatively define a cavity sized to accommodate an ear of a user, the earpiece cushion assembly comprising:
a protective cover;
an annular earpiece cushion; and
a support structure disposed between the annular earpiece cushion and the earpiece housing, the support structure comprising cantilevered support members distributed along a periphery of the cavity and protruding into the cavity, one or more of the cantilevered support members being embedded within the protective cover.

10. Headphones, comprising:
a headband assembly;
a first earpiece coupled to a first end of the headband assembly and a second earpiece coupled to a second end of the headband assembly, each of the first and second earpieces comprising an earpiece housing, an acoustic driver disposed within the earpiece housing and an earpiece cushion assembly coupled to the earpiece housing to cooperatively define a cavity sized to accommodate an ear of a user, the earpiece cushion assembly comprising:
an annular earpiece cushion; and
a support structure disposed between the annular earpiece cushion and the earpiece housing, the support structure comprising cantilevered support members distributed along a periphery of the cavity and protruding into the cavity; and

webbing coupling adjacent cantilevered support members together.

11. The headphones as recited in claim 10 , wherein a stiffness of the webbing is lower than a stiffness of the cantilevered support members.

12. An earpiece suitable for use with over-ear headphones, the earpiece comprising:
an earpiece housing;
an earpiece cushion assembly coupled to the earpiece housing to cooperatively define a cavity sized to accommodate an ear of a user, the earpiece cushion assembly comprising an annular earpiece cushion and an annular support structure disposed between the annular earpiece cushion and the earpiece housing, the annular earpiece cushion comprising a cushion disposed within a protective cover and the annular support structure comprising a plurality of cantilevered support members distributed around the cavity and protruding laterally into a central opening defined by the annular support structure; and
an acoustic driver.

13. The earpiece as recited in claim 12 , wherein an interior-facing surface of the annular earpiece cushion and an adjacent interior surface of the earpiece housing operate to form an undercut.

14. The earpiece as recited in claim 12 , wherein each of the cantilevered support members have the same size and shape.

15. The earpiece as recited in claim 12 , wherein each of the cantilevered support members curve toward the annular earpiece cushion.

16. The headphones as recited in claim 12 wherein each of the plurality of cantilevered support members is sized and shaped to allow the cantilevered support member to deflect independently from adjacent ones of the cantilevered support members when the headphones are worn by a user.

17. The headphones as recited in claim 12 wherein the annular earphone cushion comprises a foam cushion disposed within a protective cover.

18. An earpiece suitable for use with over-ear headphones, the earpiece comprising:
an earpiece housing;
an earpiece cushion assembly coupled to the earpiece housing to cooperatively define a cavity sized to accommodate an ear of a user, the earpiece cushion assembly comprising an annular earpiece cushion, a protective cover, and a support structure disposed between the annular earpiece cushion and the earpiece housing, the support structure comprising cantilevered support members distributed around the cavity and protruding into the cavity, one or more of the cantilevered support members being embedded within the protective cover; and
an acoustic driver.

19. An earpiece suitable for use with over-ear headphones, the earpiece comprising:
an earpiece housing;
an earpiece cushion assembly coupled to the earpiece housing to cooperatively define a cavity sized to accommodate an ear of a user, the earpiece cushion assembly comprising an annular earpiece cushion and a support structure disposed between the annular earpiece cushion and the earpiece housing, the support structure comprising cantilevered support members distributed around the cavity and protruding into the cavity, a first one
