| abstract | (57) [Problem] To improve cavitation generated in a propagation medium due to a negative pressure wave of a shock wave to improve propagation efficiency. SOLUTION: An ultrasonic wave generating source 3 is formed by bonding first and second spherical vibrators 1 and 2 made of piezoelectric ceramics. And the pulse controller 4 However, when the first vibrator 1 is driven to generate a shock wave, the second vibrator generates a positive pressure wave having the same amplitude at the timing when the first negative pressure wave of the shock wave is generated. 2 Drive. Further, the second vibrator 2 is driven so as to generate a negative pressure wave and a positive pressure wave having the same amplitude at the timing of generating the positive pressure wave and the negative pressure wave after the second wave of the shock wave. This makes it possible to cancel all the after-waves other than the first positive pressure wave of the shock wave, to prevent inconvenience of cavitation in the propagation medium, and to improve the propagation efficiency. |
