Percussion device

1. A percussion device comprised of:

a platform portion composed of a first material having an exposed striking portion composed of a second material;

a base portion separated from, and substantially parallel to, the platform portion by a predetermined distance;

at least one unitary sidewall portion positioned between the platform portion and the base portion at respective opposing edges of the platform portion and the base portion; and

a non-flexible surface below, and in direct contact with, a portion of an underside of the exposed striking portion.

2. The percussion device of claim 1 further comprising a second unitary sidewall portion joining the platform portion and the base portion at second respective opposing edges of the platform portion and the base portion.

3. The percussion device of claim 1 wherein the base portion and the at least one unitary sidewall portion are each composed of the first material.

4. The percussion device of claim 1 wherein the platform portion, the base portion and the at least one unitary sidewall portion together form a unitary percussion device structure.

5. The percussion device of claim 1 further comprising at least one attachment structure on an exposed surface of the base portion.

6. The percussion device of claim 1 wherein the striking portion is within a depression formed within a surface of the platform portion.

7. The percussion device of claim 1 wherein the percussion device is substantially rectangular-shaped.

8. The percussion device of claim 1 wherein the percussion device is substantially round-shaped.

9. The percussion device of claim 1 wherein the percussion device is sized such that striking an exposed surface of the exposed striking portion with a striking device creates a sound of a predetermined pitch.

10. The percussion device of claim 1 wherein the second material is different than the first material.

11. The percussion device of claim 1 further comprising an insert portion comprised of a third material sized to reversibly fit at least partially within a space defined by (a) the striking portion, (b) the base portion and (c) the at least one unitary sidewall portion.

12. The percussion device of claim 5 wherein the percussion device is reversibly affixed to an obverse side of a mounting structure using the at least one attachment structure on the exposed surface of the base portion and an opposing attachment structure on an obverse side of the mounting structure.

13. The percussion device of claim 11 wherein the attachment structures on the base portion is one of a hook attachment structure and a loop attachment structure, and the attachment structures on the mounting structure is another of the hook attachment structure and the loop attachment structure.

14. The percussion device of claim 12 wherein the mounting structure includes a threaded opening on a reverse side, the threaded opening substantially being at the center of the reverse side.

15. The percussion device of claim 1 wherein the striking portion is composed of a resilient material.

16. The percussion device of claim 1 wherein the platform portion, the base portion and the at least one unitary sidewall portion are each comprised of wood or plastic, the striking portion is comprised of natural gum rubber, a synthetic rubber or silicone.

17. A percussion device comprised of:

a platform portion composed of a first material having an exposed striking portion composed of a second material on an obverse side of the platform portion;

a base portion separated from, and substantially parallel to, the platform portion by a predetermined distance;

at least one unitary sidewall portion positioned between the platform portion and the base portion at respective opposing edges of the platform portion and the base portion; and

a cavity formed through the base portion and into the platform portion.

18. The percussion device of claim 17 further comprising a muffler sized to fit within the cavity.

19. The percussion device of claim 18 wherein the cavity is a generally central cavity, and the muffler includes an outwardly extending lip about the periphery of an end of the muffler exposed when the muffler is within the generally central cavity, the lip contacting an exposed lower surface of the base portion.

20. A percussion device comprising:

(1) an upper platform portion comprised of a first material including a striking portion comprised of a second material different from the first material;

(2) a lower base portion comprised of a third material;

(3) at least one unitary sidewall portion comprised of the first material, positioned between the upper platform portion and the lower base portion along opposing edges of the upper platform portion and the lower base portion;

(4) a resonating cavity within the percussion device defined by at least (a) a lower surface of the upper platform portion, (b) interior sidewalls of the at least one unitary sidewall portion, and (c) a portion of the lower base portion; and

(5) at least one cavity opening formed through a portion of the at least one unitary sidewall portion, the at least one opening communicating with the resonating cavity.
