ULTRASONIC GENERATOR AND ULTRASONIC OSCILLATOR FOR SCANNING BROADER SKIN AREA IN A SHORT TIME

摘要

PURPOSE: An ultrasonic generator and ultrasonic oscillator are provided to cure wide domain of skin in a short time by controlling phase difference using an ultrasonic oscillator and irradiating ultrasound.;CONSTITUTION: An ultrasonic generator and ultrasonic oscillator comprises two symmetric sonic wave transducer devices which are symmetrical, an ultrasonic oscillator(10) which generates unltrasound having one focal region according to phase difference; an ultrasonic driver(20) which drives the ultrasonic oscillator; a control unit(30) which controls the ultrasound driver by diversifying phase differences between sonic wave converter devices to adjust the number of focal region of ultrasound; and a supersonic output unit(40) which irradiates ultrasound generated from the ultrasonic oscillator to skin.;COPYRIGHT KIPO 2013;[Reference numerals] (10) Ultrasonic oscillator; (20) Ultrasonic driver; (30) Control unit; (40) Ultrasonic output unit; (50) Power circuit controller DAC, sensing circuit; (60) Power circuit(asymmetric half-bridge)
