Free-standing wireless-charging headsets
View Patent ↗Headsets of the inventive subject matter are configured to stand freely on an outer surface of an earcup, and they incorporate wireless charging in one or more earcups so that the headset can be wirelessly charged while resting on an outer surface of an earcup. To make this charging configuration possible, one or more holding mechanisms are implemented to couple one or both of the fork bodies (e.g., the structure to which an earcup is coupled) to the headband of a headset. Holding mechanisms of the inventive subject matter prevent the headset from toppling over while charging due to rotation of the headband relative to the earcup that the headset is resting on.
1. A free-standing wireless charging headset, comprising:
a headband;
a fork body coupled with the headband by a holding mechanism;
an earcup coupled with the fork body and comprising an outer surface and wireless charging coils positioned behind the outer surface, thereby enabling the wireless charging headset to wirelessly charge when resting on the outer surface of the earcup;
wherein the holding mechanism comprises a shaft to couple the headband with the fork body, at least one ball bearing mechanism comprising a spring-loaded ball bearing, and at least one complementary indentation to receive the spring-loaded ball bearing;
wherein the holding mechanism is configured to releasably hold the headband in alignment with the fork body, thereby preventing the wireless charging headset from falling when resting on the outer surface of the earcup; and
wherein the shaft facilitates rotation of the headband relative to the fork body about a single axis of rotation.
2. The headset of claim 1 , wherein the outer surface comprises at least one of a rubber and a plastic.
3. The headset of claim 1 , wherein the at least one ball bearing mechanism is coupled with the fork body and wherein the headband comprises the at least one complementary indentation.
4. The headset of claim 1 , wherein the at least one ball bearing mechanism is coupled with the headband and wherein the fork body comprises the at least one complementary indentation.
5. The headset of claim 1 , wherein the wireless charging coils are sized and dimensioned to achieve maximum resonance with a complementary charging coil at a power transmission frequency between 87 kHz and 205 kHz.
6. The headset of claim 1 , further comprising:
a second fork body coupled with the headband by a second holding mechanism;
a second earcup coupled with the second fork body and comprising a second outer surface and second wireless charging coils positioned behind the second outer surface so that the wireless charging headset can wirelessly charge when resting on the second outer surface of the second earcup;
the second holding mechanism comprising a second shaft to couple the headband with the second fork body, at least a second ball bearing mechanism comprising a second spring-loaded ball bearing, and at least a second complementary indentation to receive the second spring-loaded ball bearing; and
the second holding mechanism configured to releasably hold the headband in alignment with the second fork body to prevent the wireless charging headset from falling over when resting on the second outer surface of the second earcup;
wherein the second shaft facilitates rotation of the headband relative to the second fork body about a second single axis of rotation.
7. A free-standing headset, comprising:
a headband;
a fork body coupled with the headband by a holding mechanism;
an earcup coupled with the fork body and comprising a flat outer surface;
the holding mechanism comprising a shaft to couple the headband with the fork body, at least one ball bearing mechanism comprising a spring-loaded ball bearing, and at least one complementary indentation to receive the spring-loaded ball bearing;
the holding mechanism configured to releasably hold the headband in alignment with the fork body to prevent the free-standing headset from falling over when resting on the outer surface of the earcup; and
wherein the shaft facilitates rotation of the headband relative to the fork body about a single axis of rotation.
8. The headset of claim 7 , wherein the outer surface comprises at least one of a rubber and a plastic.
9. The headset of claim 7 , wherein the at least one ball bearing mechanism is coupled with the fork body and wherein the headband comprises the at least one complementary indentation.
10. The headset of claim 7 , wherein the at least one ball bearing mechanism is coupled with the headband and wherein the fork body comprises the at least one complementary indentation.
11. The headset of claim 7 , wherein the at least one ball bearing mechanism is offset from the shaft.
