Embodiment 1
[0036] Natural rubber (hardness: Shore A60, thickness 6 mm) is used as the main body part 61, polyethylene terephthalate (thickness: 100 μm) is used as the surface layer part 62, and they are bonded with an epoxy resin adhesive. Drum pad 6, using this drum pad 6 to make figure 2 An electronic drum of the structure shown.
[0037]The drum pad 6 has good resilience, improves the impact feeling, and attenuates the impact sound well, and can obtain good quietness. In addition, it is also possible to suppress damage to the shock and deterioration of the main body due to oxygen or moisture in the air.
Embodiment 2
[0039] An olefinic thermoplastic elastomer (manufactured by JSR Corporation, product number TEL424 developed product, hardness: Shore A20, thickness 6mm) was used as the main body portion 61, and polyurethane paint was applied as the surface layer portion 62 to form a coating layer with a thickness of 60 μm. Drum pad 6 is formed, and the drum pad is further used to manufacture the same electronic drum as in embodiment 1.
[0040] The drum pad 6 has good resilience, improves the impact feeling, and attenuates the impact sound well, and can obtain good quietness. In addition, it is also possible to suppress damage to the shock and deterioration of the main body due to oxygen or moisture in the air.
Embodiment 3
[0042] An olefinic thermoplastic elastomer (manufactured by JSR Corporation, product number TEL424 developed product, hardness: Shore A20, thickness 6mm) was used as the main body 61, and a polypropylene film (thickness: 150 μm) was fixed and bonded as the surface 62 by insert molding. And the drum pad 6 was produced, and the drum pad 6 was further used to manufacture an electronic drum in the same manner as in Example 1.
[0043] The drum pad 6 has good resilience, improves the impact feeling, and attenuates the impact sound well, and can obtain good quietness. In addition, it is also possible to suppress damage to the shock and deterioration of the main body due to oxygen or moisture in the air.

Abstract
The invention provides a pad for an electronic drum which has three characteristics of silence, durability, and a strike feeling improved at the same time, and an electronic drum equipped with the same. The pad comprises a main body part 61 made of a macromolecular elastic material such as rubber and thermoplastic elastomer and a surface layer part 62 which is joined with the main body part 61 to cover the main body 61, the surface layer part 62 being made of a macromolecular material of 0.5 to 20 GPa in elasticity modulus. The thickness of the surface layer part 62 may be 0.05 to 1mm. The surface layer part 62 may be formed of one or more layers. Further, the surface layer part 62 is formed preferably by bonding or fusing a film, a sheet, fabric, or web made of the macromolecular material, applying paint made of a macromolecular material, or performing dichroic molding or insert molding using a macromolecular material.
Description
[0001] technology area [0002] The present invention relates to a drum pad for an electronic drum that converts percussion sounds electronically and obtains musical sounds as electronic sounds, and an electronic drum including the drum pad. [0003] This application claims priority from Japanese Patent Application No. 2004-63888 filed on March 8, 2004, and its contents are used here. Background technique [0004] For example, Japanese Patent Application Laid-Open No. 9-244633 discloses such an electronic drum and a drum pad for an electronic drum as its striking surface. [0005] As the characteristics required for the material of the drum pad for electronic drums, it can be listed that the percussion sound produced by the drumstick should be quiet, the ability to withstand long-term percussion, the mechanical durability of strong percussion, and the resistance to ultraviolet rays. , chemical durability due to aging by oxygen or moisture, and the same percussive feel as an a...
