Abstract

An audio headphone to couple to a strap for a head-mounted display is disclosed. The audio headphone includes a headphone speaker, a strap connector, and a four-bar linkage coupled to the strap connector to provide movement of the headphone speaker with respect to a user's ear. The four-bar linkage comprises a first member coupled to the strap connector via a first joint, a second member coupled to the first member via a second joint, a third member coupled to the second member via a third joint, and a fourth member coupled to the third member. The fourth member has first and second sides that are coupled to the first member via a fourth joint.

First claim

What is claimed is:

1 . An audio headphone to couple to a strap for a head-mounted display, the audio headphone comprising:
a headphone speaker; a strap connector; and a four-bar linkage coupled to the strap connector to provide movement of the headphone speaker with respect to a user's ear, the four-bar linkage comprising:
a first member with a first end portion coupled to the strap connector via a first joint;
a second member with a first end portion coupled to a second end portion of the first member via a second joint;
a third member with a first end portion coupled to a second end portion of the second member via a third joint; and
a fourth member with a first portion coupled to a second end portion of the third member, and with first and second sides that are connected by the first portion and that extend to a second portion of the fourth member, wherein the first member is further coupled to the first and second sides of the fourth member via a fourth joint.

2 . The audio headphone of claim 1 , wherein the second portion of the fourth member is coupled to the strap connector via a fifth joint.

3 . The audio headphone of claim 2 , wherein:
the first member includes a bend at a mid-portion; and the mid-portion of the first member is coupled to mid-portions of the first and second sides of the fourth member at the fifth joint.

4 . The audio headphone of claim 1 , wherein the third member comprises one or more rigid poles, each of the one or more rigid poles being surrounded by a respective spring.

5 . The audio headphone of claim 4 , wherein the third member further comprises a spring cover having one or more grooves to accommodate the one or more rigid poles and respective springs.

6 . The audio headphone of claim 5 , wherein the one or more rigid poles are coupled to the second end portion of the second member via the spring cover and the third joint.

7 . The audio headphone of claim 4 , wherein the second end portion of the third member includes an end portion of each rigid pole of the one or more rigid poles.

8 . The audio headphone of claim 1 , wherein:
the four-bar linkage provides inward and outward movement of the headphone speaker with respect to the user's ear; and the inward and outward movement includes movement between a first stable position inward from a vertical plane in a range from −1° to −10°, and a second stable position outward from the vertical plane in a range from 25° to 35°.

9 . The audio headphone of claim 1 , further comprising:
a frame, coupled to the headphone speaker, wherein:
the four-bar linkage is coupled to the strap connector through an opening in the frame; and
the headphone speaker is mounted on the frame below the opening.

10 . The audio headphone of claim 9 , wherein the frame is to slide upward and downward with respect to the four-bar linkage and the strap connector.

11 . The audio headphone of claim 9 , further comprising a cover piece fixedly attached to the frame to cover the frame and the four-bar linkage from an outward side away from the user's ear, a space being formed between the cover piece and the frame for housing the four-bar linkage.

12 . The audio headphone of claim 9 , further comprising a mount;
wherein the strap connector comprises a cylindrical component that is rotatable with respect to the mount.

13 . The audio headphone of claim 12 , wherein:
the cylindrical component comprises a base part and a protruding part that protrudes from the base part; and the base part is fixedly connected to the four-bar linkage to transmit rotational motion from the cylindrical component to the four-bar linkage and the frame, such that the frame and the headphone speaker are rotatable relative to the mount.

14 . The audio headphone of claim 13 , wherein:
the mount comprises a mounting bracket to engage the protruding part of the cylindrical component such that the cylindrical component is rotatable with respect to the mounting bracket, and the mounting bracket is fixedly connectable to the strap to connect the audio headphone to the strap.

15 . The audio headphone of claim 12 , wherein the frame and the headphone speaker are rotatable relative to the mount in a range from −30° to 30° within a vertical plane.

16 . The audio headphone of claim 1 , wherein the strap connector comprises an electrical connection to electrically couple the audio headphone with the strap.

17 . An audio headphone arm to couple to a strap for a head-mounted display via a strap connector, the audio headphone arm comprising:
a four-bar linkage to provide movement of the audio headphone arm with respect to a user's ear, the four-bar linkage comprising:
a first member with a first end portion to couple to the strap connector via a first joint;
a second member with a first end portion coupled to a second end portion of the first member via a second joint;
a third member with a first end portion coupled to a second end portion of the second member via a third joint; and
a fourth member with a first portion coupled to a second end portion of the third member, and with first and second sides that are connected by the first portion and that extend vertically to a second portion of the fourth member, wherein the first member is further coupled to the first and second sides of the fourth member via a fourth joint.

18 . The audio headphone arm of claim 17 , wherein the third member comprises one or more rigid poles, each of the one or more rigid poles being surrounded by a respective spring.

19 . The audio headphone arm of claim 18 , wherein the third member further comprises a spring cover having one or more grooves to accommodate the one or more rigid poles and respective springs.

20 . The audio headphone arm of claim 19 , wherein the one or more rigid poles are coupled to the second end portion of the second member via the spring cover and the third joint.
