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

  • receiving, at a computer, information identifying a location of a receiver device that requires charging, wherein the location is within a predetermined range of the computer;

    transmitting a first set of sound waves, via one or more transducer elements of a first transmitter that is mechanically coupled with the computer, that converge proximate to the location of the receiver device to form a pocket of energy at the location, wherein the receiver device is distinct from the computer; and

    while transmitting the first set of sound waves that converge proximate to the location of the receiver device to form the pocket of energy at the location;

    receiving, at the computer, a second set of sound waves from a second transmitter, distinct from the first transmitter, andcharging the computer by converting energy from the second set of sound waves into usable electricity.
