Patent ID: 7468483

Claim:
An electronic percussion instrument comprising: a pedestal that a vertical shaft passes through, a striking surface of a flexible body that moves up and down in response to the movement of the vertical shaft, a first detection section that detects vibrations when the striking surface is struck, a second detection section that detects the vertical displacement of said striking surface, and a single cymbal comprising: a first frame that supports said striking surface, a second frame attached to the first frame, wherein the second frame forms the bottom surface opposite to said striking surface, a support section through which the shaft passes so that there is play, wherein said support section has a broad base and a narrow apex, and wherein the apex portion of said support section supports the first frame such that swinging is possible with respect to the shaft, and a seating section of the second frame which sits on the pedestal, wherein said seating section is curved on the side facing said pedestal section with a greater radius of curvature than that of the pedestal section, wherein the cymbal is attached to the shaft and moves up and down in conformance with the movement of said shaft, wherein the shaft passes through the first and the second frames with the striking surface on top, wherein a signal based on the detection results of the first and the second detection sections is output to a sound source system, wherein the pedestal is fastened to the shaft at a position lower than that of the cymbal in a state such that there is play, wherein the second frame is seated on the pedestal when the cymbal moves downward in conformance with the movement of the shaft, in the vicinity of where said shaft passes through said second frame, wherein said support section is positioned in the center of the seating section, and wherein the pedestal section forms a hollow in the direction of the curvature of the seating section such that said pedestal section roughly approximates the outer shape of said seating section in the cross-section view.
