Abstract

PURPOSE:To obtain ultrasonic waves of >=2 frequencies by varying the length of the metallic block of the titled asymmetric Langevin type vibrator and enabling driving at resonance frequency between the length of a short-sized metallic block and the vibrator and the length of a long-sized metallic block and the vibrator. CONSTITUTION:One metallic block 9 is short and the other metallic block 10 is long; and screws 5a and 5b of a bolt 5 are screwed in the screw holes of short metal 9 and long metal 10 and fixed. When an AC voltage is applied between terminals 3 and 4 of this asymmetrical Langevin type vibrator from an AC power source 11, ultrasonic waves of >=2 frequencies such as the resonance frequency of the length containing the short metallic block 9 and vibrators 1 and 2, the resonance frequency of length including the long metallic block 10 and vibrators 1 and 2, and the resonance frequency of the overall length are easily generated at a low cost.
