Abstract

A headset charging dock includes a headset mechanical support configured to hang a first headset by a headband of the first headset; and a wireless charging interface for the first headset, the wireless charging interface integrated in the headset mechanical support.

First claim

What is claimed is:

1. A charging setup of a headset, the charging setup comprising:
a wireless charging interface disposed on a headband of the headset to wirelessly charge the headset when the headset is mechanically supported by a headset charging dock at the wireless charging interface; and
a notch in the headband sized to mechanically align the headset on the headset charging dock.

2. The charging setup of claim 1 , wherein the wireless charging interface and the notch are disposed on the headband at at least one of a balancing point of the headband and a center point of the headband.

3. The charging setup of claim 1 , wherein the wireless charging interface comprises a charging receive antenna assembly, and wherein the charging receive antenna assembly comprises a thermal interface to conduct heat away therefrom.

4. The charging setup of claim 1 , further comprising:
a magnet to magnetically align the headset on the headset charging dock.

5. The charging setup of claim 1 , wherein the headband includes angled walls that define the notch.

6. The charging setup of claim 1 , wherein a position of the notch along the headband corresponds to a sagittal crest of a head of a user.

7. The charging setup of claim 1 , wherein the headset charging dock comprises at least one of an under-desk mounting, a wall-mounting, and a divider wall-mounting.

8. The charging setup of claim 1 , wherein a visual indicator is positioned in a center of the notch to identify the wireless charging interface.

9. A charging case for a headset, the charging case comprising:
a body;
a cavity defined within the body and to receive the headset therein; and
a wireless charging interface disposed within the body,
wherein the wireless charging interface enables a wireless charging of the headset by the charging case when the headset is inserted into the cavity of the charging case so that a wireless charging interface disposed on a headband of the headset is aligned with the wireless charging interface disposed within the body.

10. The charging case of claim 9 , further comprising an opening to receive an external charging transmit antenna assembly, the opening extending through the body such that the charging case defines a handle.

11. The charging case of claim 9 , wherein the charging case comprises an opening to hang from a headset charging dock.

12. The charging case of claim 9 , wherein the wireless charging interface comprises a charging transmit antenna assembly.

13. The charging case of claim 12 , wherein the charging transmit antenna assembly comprises a thermal interface to conduct heat away therefrom.

14. The charging case of claim 12 , further comprising foam padding that aligns a charging receive antenna assembly of the headset with the charging transmit antenna assembly of the wireless charging interface when the headset is received within the cavity.

15. The charging case of claim 9 , further comprising at least one magnet to magnetically align the headset within the charging case to wirelessly charge the headset with the charging case.

16. A charging case, comprising:
a lid;
a base including a cavity defined therein to receive an earbud; and
a wireless charging interface including a charging transmit antenna assembly,
wherein wireless charging of the earbud by the charging case is enabled when the earbud is inserted into the cavity of the charging case and aligned with the charging transmit antenna assembly,
wherein the charging transmit antenna assembly is disposed within the lid to charge the earbud, and
wherein the wireless charging interface is at least partially disposed within a bottom portion of the base and is configured to charge the charging case when the charging case is placed on top of a charging plate.

17. The charging case of claim 16 , wherein the earbud is aligned within the cavity when a charging receive antenna assembly disposed within the earbud faces the charging receive antenna assembly of the charging case.

18. The charging case of claim 16 , wherein the wireless charging interface supports at least one of a Qi, NFC, and Air Fuel charging standard.

19. The charging case of claim 16 , wherein the cavity is shaped to receive the earbud lying flat.

20. The charging case of claim 16 , wherein the charging transmit antenna assembly is configured to interact with a charging receive antenna assembly in a stem of the earbud.
