Abstract

A power system on an electric guitar may include a cover plate covering a standard cavity in the electric guitar. A rechargeable power source may be contained within the standard cavity and may not extend beyond an external surface of the cover plate. Other instruments or configurations may be used.

Claims

1. An electric guitar, comprising:

a first side having mounted thereon guitar strings;

a second side opposite the first side comprising a standard spring cavity, the standard spring cavity comprising springs to counterbalance the tension of the guitar strings, the standard spring cavity being created at the time of the manufacture of the guitar, the standard spring cavity having the design of the standard spring cavity of a Fender STRATOCASTER®

guitar;

a pickup to detect vibrations from the electric guitar'"'"'s strings and output a signal;

a back plate to cover the standard spring cavity, the back plate being the same size and shape as the cover originally manufactured to cover the standard spring cavity;

a rechargeable power source to provide power to the pickup;

the rechargeable power source disposed flat and parallel to the back plate;

a charging circuit to control the input and output of current to and from the rechargeable power source; and

a jack for connection to a charger.

2. The electric guitar of claim 1, wherein the rechargeable power source is disposed on an inner surface of the back plate.

3. The electric guitar of claim 1, wherein the back plate and the rechargeable power source are to replace an original back plate of the electric guitar.

4. The electric guitar of claim 1, wherein the back plate includes screw holes aligned with screw holes on the electric guitar.

5. The electric guitar of claim 1, comprising a micro USB (Universal Serial Bus) receptacle accessible through the back plate to connect power to the rechargeable power source.

6. The electric guitar of claim 1, comprising a light-emitting diode visible on the external surface of the back plate to indicate that the rechargeable power source is charging.

7. An electric guitar, comprising:

a first side having mounted thereon guitar strings;

a standard control cavity on the second side, the standard control cavity being created at the time of the manufacture of the guitar, the standard control cavity having the design of the standard control cavity of a Gibson LES PAUL guitar;

a pickup to detect vibrations from the electric guitar'"'"'s strings and output a signal;

a back plate to cover the standard control cavity, the back plate being the same size and shape as the cover originally manufactured to cover the standard control cavity;

a rechargeable power source adhered to the back plate, and extending from the back plate into the control cavity and extending slightly and less than half an inch from the back plate beyond the shape of the guitar to provide power to the pickup;

a charging circuit to control the input and output of current to and from the rechargeable power source;

the rechargeable power source and charging circuit contained within the standard control cavity; and

a jack for connection to a charger.

8. The electric guitar of claim 7, wherein the rechargeable power source is disposed on an inner surface of the back plate.

9. The electric guitar of claim 7, wherein the back plate includes screw holes aligned with screw holes on the electric guitar.

10. The electric guitar of claim 7, comprising a micro USB (Universal Serial Bus) receptacle accessible through the back plate to connect power to the rechargeable power source.

11. The electric guitar of claim 7, comprising a light-emitting diode visible on the external surface of the back plate to indicate that the rechargeable power source is charging.

12. The electric guitar of claim 7, wherein the back plate and the rechargeable power source are to replace an original back plate of the electric guitar.

13. An electric guitar, comprising:

a first side having mounted thereon guitar strings;

a standard control cavity on the second side, the standard control cavity being created at the time of the manufacture of the guitar, the standard control cavity having the design of the standard control cavity of a Gibson LES PAUL guitar;

a pickup to detect vibrations from the electric guitar'"'"'s strings and output a signal;

a back plate to cover the standard control cavity, the back plate being the same size and shape as the cover originally manufactured to cover the standard control cavity;

a rechargeable power source adhered to the back plate, and extending from the back plate into the control cavity to provide power to the pickup;

a charging circuit to control the input and output of current to and from the rechargeable power source;

the rechargeable power source and charging circuit contained within the standard control cavity; and

a jack for connection to a charger.

14. The electric guitar of claim 13, wherein the back plate includes screw holes aligned with screw holes on the electric guitar.

15. The electric guitar of claim 13, comprising a micro USB (Universal Serial Bus) receptacle accessible through the back plate to connect power to the rechargeable power source.

16. The electric guitar of claim 13, comprising a light-emitting diode visible on the external surface of the back plate to indicate that the rechargeable power source is charging.

17. The electric guitar of claim 13, wherein the back plate and the rechargeable power source are to replace an original back plate of the electric guitar.

18. An electric guitar comprising:

a first side having mounted thereon guitar strings;

a standard pre-existing control cavity disposed on the second side, the standard control cavity being created at the time of the manufacture of the guitar;

a pickup to detect vibrations from the electric guitar'"'"'s strings and output a signal;

a back plate to cover the standard control cavity, the back plate being the same size and shape, and having same screw alignment, as the cover originally manufactured to cover the standard control cavity;

a rechargeable power source and a circuit board contained within the standard control cavity to provide power to the pickup;

a charging circuit to control the input and output of current to and from the rechargeable power source;

the rechargeable power source, circuit board, and charging circuit contained entirely within the standard control cavity, and not requiring modification to the guitar'"'"'s body structure when the back plate is fastened to the guitar; and

a jack for connection to a charger, the jack being in a receptacle passing through the back plate.

19. The electric guitar of claim 18, wherein the rechargeable power source is disposed on an inner surface of the back plate.
