1. A method for wireless charging of a game controller, comprising:
- connecting a pocket-forming transmitter to a power source;
generating sound waves from a sound circuit embedded within the transmitter;
controlling the generated sound waves with a digital signal processor in the transmitter;
transmitting the sound waves through antenna elements connected to the transmitter to a receiver configured to capture the sound waves forming a pocket of energy in 3-D space at the receiver with antenna elements connected to the game controller to convert the pocket of energy into a DC voltage for charging or powering a battery of the gamer controller, wherein the controlled sound waves are controlled through phase and relative amplitude adjustments to form constructive interference patterns that result in the pocket of energy at the receiver for the game controller.
