Abstract

A musical instrument requiring power has a wireless resonate power receiver to receive electric energy from electromagnetic waves transmitted by a wireless resonate power transmitter when the wireless resonate power receiver is within an area covered by the wireless resonate power transmitter. The electric energy can be stored in a rechargeable power supply, such that the musical instrument can be charged wirelessly.

Claims

1. A power receiver for providing power to one or more electrical components coupled to a musical instrument, the power receiver comprising:

a resonator coupled to the musical instrument to capture electrical energy received wirelessly from an oscillating electromagnetic field; and

a rechargeable power supply coupled to the resonator to store the received electrical energy and provide power to the one or more electrical components coupled to the musical instrument.

2. The power receiver of claim 1 further comprising:

a power conditioning circuit positioned between the resonator and the rechargeable power supply to control a rate at which the electrical energy is passed to the rechargeable power supply.

3. The power receiver of claim 2 wherein the musical instrument is a standard acoustic guitar, the resonator is removeably mounted to an interior surface of a chamber of the standard acoustic guitar without modifying the interior surface, and the power conditioning circuit and the rechargeable battery are mounted on a neck block of the standard acoustic guitar.

4. The power receiver of claim 1 further comprising:

a boost converter positioned between the rechargeable battery and the one or more electrical components to boost an output voltage of the rechargeable power supply.

5. The power receiver of claim 3 wherein the boosted output voltage is between 8.5 volts and 18 volts.

6. The power receiver of claim 1 wherein captured electrical energy bypasses the rechargeable power supply and is provided directly to the one or more electrical components.

7. The power receiver of claim 1 wherein the rechargeable power supply is a battery, capacitor, or any combination thereof.

8. The power receiver of claim 1 wherein the musical instrument is a standard acoustic guitar and the resonator and the rechargeable power supply are removeably mounted to an interior surface of a chamber of the standard acoustic guitar without modifying the interior surface.

9. The power receiver of claim 1 wherein the musical instrument is an electric guitar and the resonator and the rechargeable power supply are positioned within an interior chamber of the electric guitar.

10. The power receiver of claim 1 further comprising a double-sided foam adhesive coupled to the resonator, the rechargeable power supply or both.

11. The power receiver of claim 1 wherein the resonator and the rechargeable battery are positioned within a housing, wherein the housing further comprises a width, height and length that dependent upon a size of the musical instrument, wherein the musical instrument is a standard musical instrument.

12. A wireless power system for providing power to electrical components coupled to a standard musical instrument, comprising:

a first resonator to wirelessly transmit an oscillating electromagnetic field within an area surrounding the power transmitter;

a second resonator coupled to the musical instrument to capture electrical energy received wirelessly from the oscillating electromagnetic field; and

a rechargeable power supply coupled to the second resonator to store the received electrical energy and provide power to the one or more electrical components coupled to the musical instrument.

13. The wireless power system of claim 12 further comprising:

a power conditioning circuit positioned between the second resonator and the rechargeable power supply to control a rate at which the electrical energy is passed to the rechargeable power supply.

14. The wireless power system of claim 12 wherein the first resonator is coupled to a standard guitar stand, a standard guitar case, a charging mat, a portable pack, or any combination thereof.

15. The wireless power system of claim 13 further comprising a sensor coupled to the first resonator to sense whether the second resonator is within the area.

16. The wireless power system of claim 12 further comprising:

a boost converter positioned between the rechargeable battery and the one or more electrical components to boost an output voltage of the rechargeable power supply.

17. The wireless power system of claim 16 wherein the boosted output voltage is between 8.5 volts and 18 volts.

18. The wireless power system of claim 12 wherein the rechargeable power source is a battery, a capacitor, or any combination thereof.

19. The wireless power system of claim 12 wherein the captured electrical energy bypasses the rechargeable power supply and is provided directly to the one or more electrical components.

20. The wireless power system of claim 12 wherein the musical instrument is a standard acoustic guitar, the second resonator is removeably mounted to an interior surface of a chamber of the standard acoustic guitar without modifying the interior surface, and the power conditioning circuit and the rechargeable battery are mounted on a neck block of the standard acoustic guitar.

21. The wireless power system of claim 12 wherein the musical instrument is a standard acoustic guitar and the second resonator and the rechargeable power supply are removeably mounted to an interior surface of a chamber of the standard acoustic guitar without modifying the interior surface.

22. The wireless power system of claim 12 wherein the musical instrument is an electric guitar and the second resonator and the rechargeable power supply are positioned within an interior chamber of the electric guitar.

23. The wireless power system of claim 12 further comprising a double-sided foam adhesive coupled to the first resonator, the second resonator, the rechargeable power supply or both.

24. The wireless power system of claim 12 wherein the first resonator is coupled to a case for the musical instrument.

25. The wireless power system of claim 12 wherein the first resonator is powered by a battery.

26. The wireless power system of claim 12 wherein the first resonator is coupled to a first magnet and the second resonator is coupled to a second magnet, the first magnet is attracted to the second magnet when positioned within a proximity of the second magnet.

27. The wireless power system of claim 12 wherein the first resonator is coupled to an indicator light that emits light when the first resonator is in electrical communication with the second resonator.

28. The wireless power system of claim 12 wherein the rechargeable power supply is coupled to an indicator light that indicates whether the rechargeable power supply is fully charged, low charged, or being charged.

29. A power receiver for providing power to one or more electrical components coupled to a musical instrument, the power receiver comprising:

a resonator coupled to the musical instrument to capture electrical energy received wirelessly from an oscillating electromagnetic field and provide power to the one or more electrical components coupled to the musical instrument.
