Abstract: An electronic bass drum is mainly constructed by two front legs which stand substantially vertically and are parallel to each other, two rear legs whose one ends are connected to the front legs and whose other ends extend obliquely downward, a pad whose back surface is fixed to the front legs and whose front surface is striken by a player and a pickup which is attached to the back surface. The pickup detects a vibration of the pad caused by the player's strike and outputs a detection signal representing electrically the vibration. Drum sound is realized by driving a sound source such as a PCM sound source, a FM sound source in response to the detection signal.
