PURPOSE:To securely and excellently transmit the stroke force of a stick, etc., to a diaphragm by arranging a damper in a musical instrument case, and bringing the diaphragm and a drum head into contact by this damper and laminating them. CONSTITUTION:The meter 4 constituted by providing and forming integrally an elastic cylindrical support part 4a and a bellows-shaped cushion part 4b is arranged in the musical instrument case consisting of an upper case 2 and a lower case 3, and this damper 4 brings the diaphragm 5 and drum head 7 into elastic contact with each other to laminate them. Consequently, the stroke force of the stick, etc., can securely and excellently be transmitted to the diaphragm, vibration corresponding to the stroke force can accurately be detected, and a drum sound can be radiated excellently. |
