ULTRASONIC GENERATOR AND ULTRASONIC VIBRATOR

摘要

The present invention relates to an ultrasonic generator. The ultrasonic generator comprises: an ultrasonic vibrator which comprises at least one pair of sonic transducer devices comprised of two symmetrical devices, and generates ultrasonic waves having one or more focal regions according to a phase difference between the devices; an ultrasonic driver for driving the ultrasonic vibrator; a control portion for controlling the ultrasonic driver to allow the number of focal regions of sonic waves to be adjusted while varying the phase difference between the sonic transducer devices; and an ultrasonic wave output portion for irradiating ultrasonic waves, generated at the ultrasonic vibrator, to the skin. Therefore, it is possible to treat a large region of skin within a short amount of time by irradiating ultrasonic waves while controlling the phase difference between the devices.
