摘要： An ultrasonic cleaning method of using ultrasonic vibrations to clean an object that is immersed in a cleaning liquid in a cleaning tank is provided. The method includes generating a frequency modulated signal including at least two frequency modulated portions having modulation widths different from each other with a single frequency as a center frequency, such that among the at least two frequency modulated portions a frequency modulated portion having a smaller modulation width is generated at a timing when a frequency modulated portion having a larger modulation width reaches the center frequency. The method further includes generating the ultrasonic vibrations based on the frequency modulated signal and transferring the ultrasonic vibrations to the cleaning tank to clean the object.
