Seamless pivot for head-worn audio devices
The invention relates to a head-worn audio device having a first earcup, a second earcup, and a headband extending between the first earcup and the second earcup. The headband includes a spring member disposed along a longitudinal axis of the headband. The spring member has a first end and a second end. The headband also includes a first headband tube coupled to the first earcup and the first end of the spring member. Further, the headband includes a second headband tube coupled to the second earcup and the second end of the spring member. The first headband tube is configured to rotate around the first end of the spring member, and the second headband tube is configured to rotate around the second end of the spring member.
1. A head-worn audio device, comprising:
a first earcup;
a second earcup; and
a headband extending between the first earcup and the second earcup, the headband including:
a spring member disposed along a longitudinal axis of the headband, the spring member having a first end and a second end,
a first headband tube coupled to the first earcup and the first end of the spring member,
a second headband tube coupled to the second earcup and the second end of the spring member, and
an arched band enclosing the spring member between the first headband tube and the second headband tube, the arched band comprising at least one flexible region extending along the longitudinal axis of the headband,
wherein the first headband tube and the second headband tube are contiguous with the arched band, and
wherein the first headband tube is configured to rotate around the first end of the spring member and the second headband tube is configured to rotate around the second end of the spring member, the rotating causing a torsion across the at least one flexible region of the arched band enclosing the spring member.
2. The head-worn audio device of claim 1 , wherein the spring member comprises a steel material.
3. The head-worn audio device of claim 1 , wherein the spring member comprises a U-shaped, cylindrical wire having a substantially uniform circular cross-sectional area.
4. The head-worn audio device of claim 3 , wherein the first end of the spring member includes a first J-shaped bend, and the second end of the spring member includes a second J-shaped bend.
5. The head-worn audio device of claim 4 , wherein the first headband tube includes a first detent configured to limit the rotation of the first headband tube around the first end of the spring member, and the second headband tube includes a second detent configured to limit the rotation of the second headband tube around the second end of the spring member.
6. The head-worn audio device of claim 1 , the headband including:
an apex approximately midway between the first headband tube and the second headband tube,
wherein the at least one flexible region is between at least one of the headband tubes and the apex.
7. The head-worn audio device of claim 6 , wherein the headband includes a first flexible region between the first headband tube and the apex, and a second flexible region between the second headband tube and the apex.
8. The head-worn audio device of claim 6 , wherein the at least one flexible region of the headband includes an elastomeric element.
9. The head-worn audio device of claim 6 , wherein the at least one flexible region of the headband includes a fabric material.
10. A head-worn audio device, comprising:
an earcup; and
a headband extending from the earcup, the headband including:
a spring member disposed along a longitudinal axis of the headband, the spring member having a first end and a second end, and
a headband tube coupled to the earcup and the first end of the spring member,
a temple-pad coupled to the second end of the spring member, and
an arched band enclosing the spring member between the headband tube and the temple-pad, the arched band comprising at least one flexible region extending along the longitudinal axis of the headband,
wherein the headband tube and the temple-pad are contiguous with the arched band, and
wherein the headband tube is configured to rotate around the first end of the spring member.
11. The head-worn audio device of claim 10 , wherein the spring member comprises a steel material.
12. The head-worn audio device of claim 10 , wherein the first end of the spring member includes a J-shaped bend.
13. The head-worn audio device of claim 10 , wherein the headband tube includes a detent configured to limit the rotation of the headband tube around the first end of the spring member.
