Abstract
A method and system for a headset wireless charging dock, where the charging dock comprises a radio frequency (RF) radio, a charging induction coil, and a proximity sensor. The method may comprise sensing a presence of a headset using the proximity sensor, wirelessly charging a battery in the headset utilizing the charging induction coil, and wirelessly communicating commands, using the RF radio, to the headset to power down at least a portion of circuitry in the headset. The command may be communicated to the headset utilizing a protocol and a RF radio used by the headset to receive audio signals. The command communicated to the headset may power down audio processing circuitry in the headset. The charging induction coil may be inductively coupled to a coil in the headset to wirelessly charge the battery in the headset. The proximity sensor may comprise a Hall sensor.
