PROBLEM TO BE SOLVED: To provide constitution capable of easily and automatically play a violin with a stereophonic sound source by entering a stereophonic audio signal. SOLUTION: A vibration part having two piezoelectric diaphragms which vibrate with the stereophonic audio signal is fixed while shouldered on a bridge of the violin through a structure to stereophonically excite the bridge, and then a top plate, a sound post, a bass bar, and a back plate are systematically excited exactly in the same manner with normal string vibrations to automatically play the violin.
