Abstract
A frequency-adjustable water dripping device. The water dripping device includes a U-shaped magnetic conductive cup, a printed circuit board (PCB), a magnetic field generating device, a water containing cavity, and a water outlet, where the U-shaped magnetic conductive cup is connected to the magnetic field generating device, and the magnetic field generating device is connected to the PCB. When alternating current signals with different frequencies are input into the PCB and sent to the magnetic field generating device, a volume of the water containing cavity is changed by means of a magnetic field generated by the magnetic field generating device, such that different water dripping effects are generated. According to the frequency-adjustable water dripping device, the volume of the water containing cavity is changed by means of the generated magnetic field, such that different water dripping effects are generated.
