System and methods for using sound waves to wirelessly deliver power to electronic devices

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;
• and
• converting, by a plurality of sensor elements included in the receiver, the pocket of energy into a DC voltage for charging or powering a battery of the gamer controller, wherein a respective one of the plurality of sensor elements produces an electrical analog output signal proportional to the controlled sound waves captured, and wherein the controlled sound waves form constructive interference patterns that result in the pocket of energy at the receiver for the game controller.

A wireless device for transmission of power to a game controller, comprising:

• a pocket-forming transmitter for emitting power sound waves to form a pocket of energy to converge in 3-D space connected to a power source;
• a receiver embedded or attached to the game controller for receiving and converting the pocket of energy to a DC voltage for charging or powering a battery of the game controller, the receiver comprises a plurality of sensor elements distributed based on a design of the game controller;
• and
• a controller configured to control the sound waves to form constructive interference patterns that result in the pocket of energy at the receiver for the game controller.

An apparatus for wireless power transmission to a game controller, comprising:

• a battery connected to the game controller;
• a pocket-forming transmitter having at least two or more transducer elements, at least one sound integrated circuit, at least one digital signal processor or micro-controller and a communication circuit for generating controlled sound waves to form a pocket of energy consisting of constructive interference patterns of the generated sound waves to converge in 3-D space at predetermined locations;
• and
• a receiver embedded or attached to the game controller having at least one antenna element, at least one rectifier, at least one power converter, a plurality of sensor elements, and a communication circuit for communicating with the transmitter a location and power requirements of the game controller for receiving the pocket of energy converging in the 3-D space at the receiver to charge or power the game controller, wherein a respective one of the plurality of sensor elements produces an electrical analog output signal proportional to sound waves in the pocket of energy.
