1. A method of wirelessly transmitting power using sound waves, comprising:

  • receiving, by a base station that is in communication with a plurality of wireless-power transmitters, data that is used to determine a location of and a power requirement for an electronic device coupled to a wireless-power receiver, wherein each of the plurality of wireless-power transmitters includes respective transducers for transmitting sound waves;

    selecting, by the base station and based on the location of the electronic device, one or more of the plurality of wireless-power transmitters to transmit sound waves to the wireless-power receiver; and

    sending, by the base station, an instruction to the one or more of the plurality of wireless-power transmitters to transmit a plurality of sound waves using respective transducers, the plurality of sound waves forming a pocket of energy proximate to the electronic device, wherein the wireless-power receiver converts energy from the plurality of sounds waves that form the pocket of energy into usable power to provide power or charge to the electronic device.
