5. The method of claim 1 , wherein the receiver device is a first peripheral device of a plurality of peripheral devices associated with the computer, and the method further comprises:
determining that a second peripheral device of the plurality of peripheral devices is not within the predetermined range of the computer; and
in accordance with determining that the second peripheral device of the plurality of peripheral devices is not within the predetermined range of the computer, selecting the second transmitter to deliver wireless power to the second peripheral device.
6. The method of claim 1 , further comprising:
while transmitting the first set of sound waves, determining whether an additional receiver device is located within the predetermined range of the computer; and
in accordance with determining that the additional receiver device is located with the predetermined range of the computer, transmitting by the first transmitter additional sound waves that converge proximate to a location of the additional receiver device to form an additional pocket of energy at the location of the additional receiver device.
7. The method of claim 1 , wherein the computer uses the one or more transducer elements to receive the second set of sound waves from the second transmitter.
8. The method of claim 7 , wherein the computer is a laptop computer, and the one or more transducer elements are embedded in the laptop computer.
9. The method of claim 8 , wherein the one or more transducer elements are embedded in a screen of the laptop computer.
10. The method of claim 1 , wherein the predetermined range is a range between one and three meters away from the computer.
11. The method of claim 1 , wherein the computer is a laptop, a desktop computer, or a tablet.
12. The method of claim 1 , wherein the receiver device comprises an electronic device that is coupled with a plurality of antenna elements for receiving the first set of sound waves.
13. The method of claim 12 , wherein the electronic device is a peripheral device associated with the computer.
14. The method of claim 13 , wherein the peripheral device is selected from the group consisting of: a mouse, a keyboard, a headset, and a smartphone.
15. The method of claim 1 , wherein the receiver device is a first receiver device of a plurality of receiver devices, and the method further comprises:
receiving, at the computer, additional information identifying a location of a second receiver device of the plurality of receiver devices that requires charging, wherein the location of the second receiver device is within the predetermined range of the computer.
16. The method of claim 15 , further comprising:
establishing a charging order for the first and second receiver devices; and
transmitting one or more sets of sound waves to the first and second receiver devices in accordance with the established charging order.
17. The method of claim 1 , wherein transmitting the first set of sound waves includes:
receiving, at the computer, instructions from the second transmitter to transmit the first set of sound waves to the receiver device.
18. The method of claim 1 , wherein the second transmitter is a higher power transmitter than the first transmitter.
19. A computer, comprising:
a first transmitter having one or more transducer elements;
one or more processors; and
memory storing one or more programs, which when executed by the one or more processors, cause the computer to:
receive, at the computer, information identifying a location of a receiver device that requires charging, wherein the location is within a predetermined range of the computer;
transmit a first set of sound waves, via the one or more transducer elements, 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:
receive, at the computer, a second set of sound waves from a second transmitter, distinct from the first transmitter, and
charge the computer by converting energy from the second set of sound waves into usable electricity.
20. A non-transitory computer-readable storage medium, storing one or more programs configured for execution by one or more processors of a computer, the one or more programs including instructions, which when executed by the one or more processors cause the computer to:
