Abstract
(EN)
An embodiment of the present invention provides an ultrasonic wave amplifying unit which can improve the output of an ultrasonic wave in the air. The ultrasonic wave amplifying unit comprises a plurality of rings having a concentric axis, wherein each of the rings is formed to have a first width, a slit having a second width is formed between the rings, and an air layer is formed between the plurality of rings and a generation medium through which an ultrasonic wave is generated or a transfer medium for transferring the ultrasonic wave.
