Abstract

An electronic drum pad includes a drum shell; a mesh head stretched at the upper opening of the drum shell; a hard-resin sheet disposed adjacent to the rear surface of the mesh head and having a ring shape with an opening made at a center thereof; a cloth disposed adjacent to the rear surface of the hard-resin sheet; a strike absorbing member disposed adjacent to the rear surface of the cloth and formed by overlaying a plurality of sheets; and a tray disposed adjacent to the rear surface of the strike absorbing member and fitted into the lower opening of the drum shell.

Claims (53)

1. An electronic drum pad comprising:

a drum shell;

a mesh head stretched at an upper opening of the drum shell;

a hard-resin sheet disposed adjacent to a rear surface of the mesh head and having a ring shape with an opening made at a center thereof;

a cloth disposed adjacent to a rear surface of the hard-resin sheet;

a strike absorbing member disposed adjacent to a rear surface of the cloth and formed by overlaying a plurality of sheets; and

a tray disposed adjacent to a rear surface of the strike absorbing member and fitted into a lower opening of the drum shell.

2. The electronic drum pad according to claim 1 , wherein the plurality of sheets comprise at least, in the following order, a porous resin sheet, a rubber sheet, and a resin emulsion sheet.

3. The electronic drum pad according to claim 2 , further comprising:

a second hard-resin sheet and a second rubber sheet both sandwiched between the porous resin sheet and the rubber sheet;

wherein the second hard-resin sheet and the second rubber sheet are formed smaller than the opening of the hard-resin sheet and are disposed at positions such that shapes made by projecting the second hard-resin sheet and the second rubber sheet from above are included in a shape made by projecting the opening of the hard-resin sheet from above.

4. The electronic drum pad according to claim 1 , further comprising an edge-sensor assembly disposed at a position close to an inner wall of the drum shell,

wherein the edge-sensor assembly comprises:

a first cushion member contacting with the rear surface of the hard-resin sheet;

an edge sensor contacting with a rear surface of the first cushion member;

a second cushion member contacting with a rear surface of the edge sensor; and

a pedestal contacting with a rear surface of the second cushion member and connecting to a front surface of the tray.

5. The electronic drum pad according to claim 2 , further comprising an edge-sensor assembly disposed at a position close to an inner wall of the drum shell,

wherein the edge-sensor assembly comprises:

a first cushion member contacting with the rear surface of the hard-resin sheet;

an edge sensor contacting with a rear surface of the first cushion member;

a second cushion member contacting with a rear surface of the edge sensor; and

a pedestal contacting with a rear surface of the second cushion member and connecting to a front surface of the tray.

6. The electronic drum pad according to claim 3 , further comprising an edge-sensor assembly disposed at a position close to an inner wall of the drum shell,

wherein the edge-sensor assembly comprises:

a first cushion member contacting with the rear surface of the hard-resin sheet;

an edge sensor contacting with a rear surface of the first cushion member;

a second cushion member contacting with a rear surface of the edge sensor; and

a pedestal contacting with a rear surface of the second cushion member and connecting to a front surface of the tray.

7. The electronic drum pad according to claim 1 , further comprising:

a plate bonded to a center of a rear surface of the tray; and

a center sensor bonded to a rear surface of the plate.

8. The electronic drum pad according to claim 2 , further comprising:

a plate bonded to a center of a rear surface of the tray; and

a center sensor bonded to a rear surface of the plate.

9. The electronic drum pad according to claim 3 , further comprising:

a plate bonded to a center of a rear surface of the tray; and

a center sensor bonded to a rear surface of the plate.

10. The electronic drum pad according to claim 4 , further comprising:

a plate bonded to a center of a rear surface of the tray; and

a center sensor bonded to a rear surface of the plate.

11. The electronic drum pad according to claim 7 ,

wherein the plate has a ring shape with a hole made at a center thereof; and

the center sensor is bonded to the rear surface of the plate so as not to overlap with the hole.

12. The electronic drum pad according to claim 8 ,

wherein the plate has a ring shape with a hole made at a center thereof; and

the center sensor is bonded to the rear surface of the plate so as not to overlap with the hole.

13. The electronic drum pad according to claim 9 ,

wherein the plate has a ring shape with a hole made at a center thereof; and

the center sensor is bonded to the rear surface of the plate so as not to overlap with the hole.

14. The electronic drum pad according to claim 10 ,

wherein the plate has a ring shape with a hole made at a center thereof; and

the center sensor is bonded to the rear surface of the plate so as not to overlap with the hole.
