To provide an electronic percussion that ensures reproducing further faithful musical sound relative to a hitting operation by a player. An electronic percussionincludes a thin plate-shaped headat an opening formed into a shape of a cylinder with a closed bottom and respective pressure sensorand signal processing deviceon a bottom. A surface of the headconstitutes a struck surface. The headincludes a vibration sensoron the back surface. The vibration sensorincludes a pressure sensor pressing bodyon the pressure sensorside. The pressure sensor pressing bodyis formed to have a tapered shape whose outer diameter gradually thins from the vibration sensorside to the pressure sensorside. The signal processing deviceoutputs a musical sound signal representing a musical sound using respective detection signals of the vibration sensorand the pressure sensor

Electronic percussion

An electronic percussion includes: a plate-shaped head constituting a struck surface beaten by a player; a frame formed into an annular frame shape surrounding an outer edge of the head, the frame holding the head via the outer edge; and a hitting sensor configured to detect at least one of a vibration and a pressure generated by hitting of the head to output an electrical signal. The frame includes: a first holding groove formed into a groove shape at an inner surface of the frame, the outer edge of the head being engaged with the first holding groove such that the head is held; and a second holding groove formed into a groove shape at a position adjacent to and along the first holding groove such that the second holding groove communicates with the first holding groove, the second holding groove having a depth deeper than a depth of the first holding groove.
