Abstract
This disclosure relates to wireless battery charging of electronic devices such as wireless headsets/headphones. In one embodiment, an electronic device is provided comprising a speaker comprising a coil, and the coil is operative both to cause the speaker to produce sound and to receive energy transferred to the coil via inductive coupling. The received energy is used to recharge a rechargeable battery in the electronic device. In other embodiments, the coil used to receive the energy that recharges the battery is received by a coil other than the coil in the speaker.
Claims18
An electronic device comprising:
- a rechargeable battery;
- a speaker comprising a coil, wherein the coil is operative both to cause the speaker to produce sound and to receive energy transferred to the coil via inductive coupling;
- and
- a battery charging circuit in communication with the coil such that energy transferred to the coil via inductive coupling is provided to the battery charging circuit, wherein the battery charging circuit is in communication with the rechargeable battery and is operative to recharge the rechargeable battery with energy transferred to the coil via inductive coupling.
A headset apparatus comprising:
- a rechargeable battery;
- a microphone;
- a speaker comprising a coil, wherein the coil is operative both to cause the speaker to produce sound and to receive energy transferred to the coil via inductive coupling;
- and
- a battery charging circuit in communication with the coil such that energy transferred to the coil via inductive coupling is provided to the battery charging circuit, wherein the battery charging circuit is in communication with the rechargeable battery and is operative to recharge the rechargeable battery with energy transferred to the coil via inductive coupling.
A system comprising:
- an electronic device comprising:
- a rechargeable battery;
- a speaker comprising a first coil, wherein the first coil is operative both to cause the speaker to produce sound and to receive energy transferred to the first coil via inductive coupling;
- and
- a battery charging circuit in communication with the first coil such that energy transferred to the first coil via inductive coupling is provided to the battery charging circuit, wherein the battery charging circuit is in communication with the rechargeable battery and is operative to recharge the rechargeable battery with energy transferred to the first coil via inductive coupling;
- and
- a power adapter comprising a second coil and operative to transfer energy to the first coil via inductive coupling.
