1. A method for transmitting wireless sound power, comprising:

  • generating two or more sound waves from a transmitter with at least two sound wave transmit transducers;

    transmitting, via the at least two sound wave transmit transducers, the two or more sound waves to cause formation of a controlled constructive interference pattern and a destructive interference pattern from the generated sound waves, wherein;

    the destructive interference pattern forms a null space that surrounds the controlled constructive interference pattern, wherein energy or power is in the form of the controlled constructive interference pattern as a pocket of sound wave energy in proximity to a targeted electronic device;

    receiving information used to determine power level of the pockets of sound wave energy and efficiency of power received by the targeted electronic device from the pocket of sound wave energy; and

    in accordance with determining that the information used to determine the power level of the pocket of sound wave energy and the efficiency of the power received by the targeted electronic device indicates that the targeted electronic device is receiving power at less than a maximum available efficiency, instructing a user of the targeted electronic device to change the targeted electronic device'"'"'s position and orientation until a level of efficiency that is no less than the maximum available efficiency is achieved for the power level received by the targeted electronic device via a receiver connected to the targeted electronic device, the receiver having at least one antenna for powering the targeted electronic device using energy from the pocket of sound wave energy.
