| 摘要 |
The present invention relates to an ultrasonic oscillator. More particularly, the ultrasonic oscillator includes an input unit which receives a command from a user, an oscillating unit which generates a plurality of currents with frequencies over 20kHz, a resonator which electrically vibrates by tuning each frequency of the currents, and a control unit which controls the operations of the oscillating unit and the resonator. The currents have different frequencies. The control unit simultaneously controls the operations of the resonator and the oscillating unit related to the currents according to a first command if the first command is inputted through the input unit.
