摘要： A case for a pair of earbuds including a housing having first and second cavities formed within the housing, the first cavity configured to receive a first earbud in the pair of earbuds and the second cavity configured to receive a second earbud in the pair of earbuds; a lid attached to the housing; a first pair of electrodes positioned within the housing adjacent to the first cavity; a second pair of electrodes positioned within the housing adjacent to the second cavity; and charging circuitry coupled to the first and second pairs of electrodes, the charging circuitry including a high frequency inverter configured to receive a DC power signal and output a high frequency AC signal to each of the first and second pairs of electrodes.

摘要： A smart speaker power controller may be configured to receive power conforming to one of a plurality of power modes from an input power source. The power controller may be further configured to communicate the power mode to at least one component of a processing system or at least one component of an audio system for operating the smart speaker according to the received power mode, including determining a current limit of a power converter; determining a shutdown voltage threshold and safely shutting down the smart speaker if the input voltage falls below the threshold, and/or modifying audio operation of the smart speaker in response to the power mode. The smart speaker can further include an audio power supply controller configured to monitor energy required to reproduce an audio signal and to servo a power supply voltage provided to an audio amplifier in response to this energy level.
