Beschreibung
Zusammenfassung:	An apparatus for generating an ultrasonic wave is provided. The apparatus for generating an ultrasonic wave comprises: an electric energy generating unit generating electric energy; and a conversion unit converting the electric energy generated in the electric energy generating unit to mechanical energy. The electric energy generating unit comprises: a function generator generating electric energy in correspondence to an input signal; an amplification circuit arranged between the electric energy generating unit and the conversion unit to control input impedance for the input impedance (Zi) of the conversion unit to be less than a predetermined value; and a driving circuit controlling operation of the function generator and the amplification circuit. 초음파 발생 장치가 제공된다. 본 초음파 발생 장치는 전기 에너지를 생성하는 전기 에너지 생성부 및 전기 에너지 생성부에서 생성된 전기 에너지를 기계 에너지로 변환시키는 변환부를 포함하며, 전기 에너지 생성부는 입력 신호에 대응하여 전기 에너지를 발생시키는 함수 발생기, 전기 에너지 생성부와 변환부 사이에 배치되어 변환부의 임력 임피던스(Zi)가 기 설정된 값 미만이 되도록 입력 임피던스를 조절하는 증폭 회로 및 함수 발생기 및 증폭 회로의 동작을 제어하는 드라이빙 회로를 포함한다.
