The invention provides a digital musical instrument of a regional slide touch control type curved surface stereo loudspeaker array. The digital musical instrument comprises a touch control input panel, a stereo curved surface loudspeaker array, and a control module. The touch control input panel comprises a touch control array and a pressure sensing module. The touch control array is used for user input and playing, and can be keys arranged in an area array or an electronic touch screen, and is used for input during simulation of playing of percussion music, wind music, and string music. The stereo curved surface loudspeaker is a stereo curved thin film loudspeaker designed and produced according to a shape of a conventional musical instrument sound-making device. A plurality of stereo curved surface loudspeakers are used to form the array, and are used to simulate the sense of space and the timbre of the corresponding musical instrument. Based on the mechanical sound-making mechanisms and the playing habits of the conventional percussion music, the conventional wind music, and the conventional string music, and the principle of the electronic musical instrument playing the sounds, the electronic musical instrument capable of playing the percussion music, the wind music, and the string music easily and having the sense of space is formed.
