PROBLEM TO BE SOLVED: To provide an electronic percussion instrument blow detection device in which difference of detection sensitivity due to a blow position is small, and excellent in responsiveness of the detection.SOLUTION: An electronic percussion instrument blow detection device 1 comprises: an elastomer vibration body 3 which vibrates by receiving blow force; and a planar sensor 4 contacting the vibration body 3 and detecting vibration of the vibration body 3, a direction F of the blow force received by the vibration body 3 and a surface of the sensor 4 being almost parallel to each other. Preferably the vibration body 3 is formed of a foam material. Preferably the vibration body 3 has a disk-shape having a blow surface on a top surface, and the sensor 4 is disposed along a peripheral surface of the vibration body 3. Preferably the peripheral surface of the vibration body 3 on which the sensor 4 is disposed has one or more salients, and the peripheral surface contacts the surface of the sensor 4 by the salients. Preferably, three or more sensors 4 are disposed on the peripheral surface of the vibration body 3 with almost equal angle intervals. |
