PURPOSE:To detect the key velocity of an operating element with a simple structure and to improve touch feeling by providing a sheet type switch which is turned on and off by an actuator and a pressure sensing sensor which is pressed by the actuator. CONSTITUTION:This electronic wind instrument is equipped with the operating element 71 which is arranged on a tube body 51 and pressed, the actuator 75 which is supported on the tube body so that is is associated operatively with the operating element 71, the sheet type switch 91 which is turned on and off by the actuator 75, and the pressure sensing sensor 93 which is pressed by the actuator 75. When the operating element 71 is pressed, the actuator 75 turns on the sheet type switch 91 and the pressure sensing sensor 93 is also pressed by the actuator. Consequently, the sheet type switch 91 outputs an ON signal and the pressure sensor 93 also generates an output signal corresponding to the operation of the actuator 75, thereby finding the velocity, etc., based upon the depression of the operating element from their output signals. Consequently, information on the key velocity and aftertouch is detected by the compact structure and the touch feeling is never spoiled. |
