Abstract
A system and method for wireless charging a wireless earbud. The wireless earbud having a body that includes a passive magnetic shield and a coil. The coil is wound around a portion of the body comprising the passive magnetic shielding. The wireless earbud receiving wireless energy in response to the placement of the body within an electromagnetic field, which results in the charging of a battery of the wireless earbud.
Claims20
A wireless power system comprising:
- an enclosure, comprising:
- a housing having:
- a receptacle for holding a receiving device, and
- a plate having a gap, the plate configured to shield electromagnetic fields, and
- a first circuit configured to:
- receive wireless energy in a first mode corresponding to a first electromagnetic field generated by an external device, and
- transmit wireless energy in a second mode corresponding to a second electromagnetic field generated by the first circuit;
- and
- the receiving device, comprising:
- a body configured to shield electromagnetic fields,
- a coil surrounding the body, and
- a second circuit configured to receive wireless energy in accordance with the first electromagnetic field and the second electromagnetic field, the receiving in response to a placement of the receiving device in the gap of the plate.
A method for operating a wireless power system comprising an enclosure and a receiving device, the method comprising:
- placing the receiving device within a respectable of a housing of the enclosure;
- shielding electromagnetic fields by a plate of the enclosure, the plate having a gap;
