Abstract
A table-type electronic percussion instrument is constructed by a table board, legs, pads as well as a musical tone generation circuit and a speaker system. Herein, the table board has a specific shape such as a pentagon-like shape which enables multiple persons to seat. The table board is supported by the legs and is constructed by a base material having a high rigidity and a dressing board like a plywood. The dressing board covers a surface of the base material through which holes are formed. The pads are arranged on a surface of the dressing board to match with locations of the holes. Sensors are provided inside of the holes and are attached to a backside of the dressing board. So, the sensors are arranged to detect striking force which is imparted to each of the pads by the persons. The musical tone generation circuit is provided beneath the table board to convert electric signals of the sensors to musical tone signals. The speaker system is located beneath the table board to generate musical tones (e.g., percussion sounds) based on the musical tone signals. For example, if the pads act like electronic drums and/or electronic cymbals, the speaker system generates drum sounds and/or cymbal sounds when the pads are struck by the persons. Thanks to the table-like construction, the electronic percussion instrument is shared by multiple persons to play an ensemble. Incidentally, the musical tone generation circuit contains a mixing circuit which performs mixing operations on the musical tone signals corresponding to the pads and other musical tone signals supplied thereto. So, the musical tone generation circuit outputs mixed musical tone signals, based on which the speaker system generates mixed musical tones.
