PURPOSE: An ultrasonic wave generator for repelling harmful insects, birds, and animals is provided to offer a manual by adjusting frequency intensity and frequency bandwidth. CONSTITUTION: An ultrasonic wave generator for repelling harmful insects, birds, and animals includes a power unit(100) and an oscillator. The power unit includes a power supplying unit supplying powder by receiving the current, and a frequency intensity controller for securing the constant voltage of the current supplied to the power supplying unit. The oscillator generates and oscillates ultrasonic waves with a waveform using the current supplied from the power unit. |
