Drum practice pad

1. A practice pad for practising the use of a snare drum, the practice pad comprising:

an upper drum surface; and

a sound generating device arranged below the drum surface;

wherein the sound generating device includes:

a chamber having a first surface and an opposing second surface; and

a plurality of elongate rods retained inside the chamber, between the first and second surfaces, so that the plurality of elongate rods vibrate against the first and second surfaces in response to a strike of the drum surface.

2. A practice pad according to claim 1 , wherein at least one of the first surface, and/or the second surface, of the chamber is a non-planar surface.

3. A practice pad according to claim 2 , wherein the non-planar surface is a domed surface, or an undulating surface.

4. A practice pad according to claim 3 , wherein the plurality of elongate rods are arranged so as to extend across the one or more undulations of the undulating surface.

5. A practice pad according to claim 3 , wherein the undulating surface is a corrugated surface.

6. A practice pad according to claim 1 , wherein at least one of the first surface, and/or the second surface, of the chamber is metallic.

7. A practice pad according to claim 1 , wherein the first and second surfaces of the chamber are configured to abut against the plurality of elongate rods with one or more of the plurality of elongate rods arranged in contact with both the first and second surfaces of the chamber.

8. A practice pad according to claim 1 , wherein the practice pad includes a first panel that defines the second surface of the chamber.

9. A practice pad according to claim 8 , wherein the practice pad includes a second panel that defines the first surface of the chamber.

10. A practice pad according to claim 9 , wherein the first panel, the second panel and the plurality of elongate rods are individually movable with respect to one another in a first direction, extending from the first surface to the second surface of the chamber, and the first panel, the second panel and the plurality of elongate rods are configured to vibrate in that direction in response to a strike of the drum surface.

11. A practice pad according to claim 10 , wherein the practice pad includes fastening elements configured to constrain the movement of the first panel with respect to the second panel, and thereby to retain the plurality of elongate rods between the first and second panels.

12. A practice pad according to claim 1 , wherein the plurality of elongate rods are arranged substantially parallel to one another.

13. A practice pad according to claim 12 , wherein the plurality of elongate rods are densely packed together, side-by-side, so as to press against one another inside the chamber.

14. A practice pad according to claim 1 , wherein one or more of the plurality of elongate rods extends at least halfway across the first surface, and/or the second surface, of the chamber.

15. A practice pad according to claim 1 , wherein the first surface of the chamber is an upper surface of the chamber arranged in a lateral plane, parallel to the drum surface, and the second surface of the chamber is an opposing lower surface of the chamber.

16. A practice pad according to claim 15 , wherein at least one of the first surface, and/or the second surface, is concentric with the drum surface.

17. A practice pad according to claim 16 , wherein at least one of the first surface, and/or the second surface, of the chamber extends under at least 50% of a lateral area defined by the drum surface.

18. A practice pad according to claim 1 , wherein the sound generating device is arranged in a cavity of the practice pad, and wherein the cavity is defined by a recess in an underside of the practice pad.

19. A practice pad for practising the use of a snare drum, the practice pad comprising:

an upper drum surface; and

a sound generating device arranged below the drum surface;

wherein the sound generating device includes:

a chamber having a first surface and an opposing second surface; and

a plurality of elongate rods retained inside the chamber, between the first and second surfaces, so that the plurality of elongate rods vibrate against the first and second surfaces in response to a strike of the drum surface;

wherein at least one of the first surface, and/or the second surface, of the chamber is a corrugated surface including a plurality of undulations, and wherein the plurality of elongate rods are arranged so as to extend across the undulations of the corrugated surface.

20. A practice pad for practising the use of a snare drum, the practice pad comprising:

an upper drum surface; and

a sound generating device arranged below the drum surface;

wherein the sound generating device includes:

a chamber having a first surface and an opposing second surface; and

a plurality of elongate rods retained inside the chamber, between the first and second surfaces, so that the plurality of elongate rods vibrate against the first and second surfaces in response to a strike of the drum surface;

wherein the practice pad includes a first panel that defines the second surface of the chamber and a second panel that defines the first surface of the chamber;

wherein the first panel, the second panel and the plurality of elongate rods are individually movable with respect to one another in a first direction, extending from the first surface to the second surface of the chamber, and the first panel, the second panel and the plurality of elongate rods are configured to vibrate in that direction in response to a strike of the drum surface; and

wherein the plurality of elongate rods are arranged substantially parallel to one another and the plurality of elongate rods are densely packed together, side-by-side, so as to press against one another inside the chamber.
