Seamless pivot for head-worn audio devices
The invention relates to a seamless pivot for a head-worn audio device. The seamless pivot includes a headband tube for interconnecting an earcup and a headband. The headband tube includes a channel extending from a top surface of the headband tube to an internal detent and an internal cavity of the headband tube. The seamless pivot also includes a spring member. A portion of the spring member is disposed within the channel of the headband tube and configured to allow rotation of the headband tube relative to the portion of the spring member. An end of the spring member terminates within at least one of the internal detent and the internal cavity of the headband tube. A range of the rotation of the headband tube, relative to the portion of the spring member within the channel, is limited by the internal detent of the headband tube.
1. A seamless pivot for a head-worn audio device, comprising:
a headband tube configured for interconnecting an earcup and a headband of a head-worn audio device, the headband tube including a channel extending from a top surface of the headband tube to an internal detent and an internal cavity of the headband tube; and
a spring member, wherein a portion of the spring member is disposed within the channel of the headband tube and configured to allow rotation of the headband tube relative to the portion of the spring member, wherein an end of the spring member terminates within at least one of the internal detent and the internal cavity of the headband tube;
wherein a range of the rotation of the headband tube, relative to the portion of the spring member within the channel, is limited by the internal detent of the headband tube.
2. The seamless pivot of claim 1 , wherein the spring member comprises a steel material.
3. The seamless pivot of claim 1 , wherein the portion of the spring member disposed within the channel of the headband tube is defined by a substantially circular cross-sectional profile.
4. The seamless pivot of claim 1 , wherein the spring member is defined by a substantially circular cross-sectional profile.
5. The seamless pivot of claim 1 , wherein the headband tube comprises:
a headband tube body having a first groove; and
a cover having a second groove, wherein the first groove and the second groove are aligned to define the channel of the headband tube.
6. The seamless pivot of claim 5 , wherein the cover is affixed to the headband tube body using one or more screws.
7. The seamless pivot of claim 1 , wherein the spring member comprises a U-shaped, cylindrical wire having a substantially uniform circular cross-sectional area.
8. The seamless pivot of claim 7 , wherein the first end of the spring member includes a J shaped bend.
