ULTRASONIC COSMETIC APPARATUS

摘要

PROBLEM TO BE SOLVED: To solve a problem in a conventional ultrasonic cosmetic apparatus wherein it is difficult to adjust a bonding position for adjusting a vibration phase because of needing to bond a plurality of solid type piezoelectric elements to a vibrating plate to enlarge ultrasonic output. SOLUTION: A Langevin type vibrator 3 is formed by holding and fixing the piezoelectric elements 4 by a horn 5 and a rear metal block 6. A depth of cut 5b is formed at the tip 5a of the horn 5 of the Langevin type vibrator 3. A part of an end 7a of the vibrating plate 7 is inserted in the depth of cut 5b, and a set screw 8 is inserted and fixed into a threaded hole 5c formed near the depth of cut 5b of the horn 5.
