<p>PURPOSE: To provide percussion instrument having long sound generation time by constituting the percussion instrument of a percussion element for starting vibration, a vibrator, additional mass for controlling a vibration mode, supporting bodies having no direct contact with the vibrator, and a resonator. CONSTITUTION: Since the vibrator 1 beated by the percussion element 104 is formed by a superconductive substance to be pushed up by lines of magnetic force applied from the supporting bodies 2, 3 having magnetism, the vibrator 1 can be vibrated without being directly brought into contact with the supporting bodies 2, 3. Since only the internal loss of the vibrator 1 and a loss of air resistance are generated, the vibration of the vibrator 1 is extremely moderately attenuated, and while being increased by the resonator 105, the vibration discharges a musical sound. Since a vibration mode can be controlled by the additional mass stuck to the vibrator 1, a musical sound having long duration can be generated.</p> |
