Abstract: The present disclosure relates to an apparatus for controlling movement of an ultrasonic wave generating unit, the apparatus characterized by comprising: a transfer unit for moving the ultrasonic wave generating unit; and a control unit for controlling the operation of the ultrasonic wave generating unit and the transfer unit, wherein the control unit controls the ultrasonic wave generating unit such that, when the ultrasonic wave generating unit moves, ultrasonic waves are irradiated at intervals to the skin on a movement path of the ultrasonic wave generating unit.

Abstract: The present invention relates to an ultrasound generation device capable of adjusting an ultrasound focus depth, comprising: a handpiece; a cartridge housing detachably coupled to the handpiece; an ultrasonic wave-generating unit provided in the handpiece or the cartridge housing; a rotating unit of which the outer circumferential surface makes contact with a support unit of the ultrasonic wave-generating unit, and which has a shape of a section with a rotation radius gradually increased from the center of the rotating unit; and a rotation adjusting unit coupled to the rotating unit to apply force for driving the rotating unit, wherein the rotating unit adjusts the focal depth of the ultrasonic waves from the ultrasonic wave-generating unit, as the rotation adjusting unit rotates the rotating unit to change a rotation radius of the rotating unit, such that the ultrasonic wave-generating unit is moved.
