Zusammenfassung: | PROBLEM TO BE SOLVED: To improve beat feeling by quickly attenuating beat vibration to accurately detect a beat from a first wave of output waveform of a beat sensor. SOLUTION: A head part 30 is arranged and supported on a shell 11 in a drum body 10. The edge of a center cushion 22 arranged on a first frame 14 fixed at the inside of the shell 11 is in contact with a rear face 31b of a flat part 31 of the head part 30. A damper cushion 23 arranged in the first frame 14 has a doughnut shape disconnected in a disconnection part 23a, and arranged so as to surround the center cushion 22. A straight line L1 connecting a center P0 of a beat region R0 to be beaten in a surface 31a of the flat part 31 of the head part 30 and a center Ps of a piezo element 26 does not interfere in front view of the head part 30 by the damper cushion 23.
