As the figure 16-7 shows, the health care toothbrush circuit uses the 555 to form a low frequency oscillator, f=1.44/(R1+RP1)C1. The figure parameter's oscillation frequency is 1-20Hz, you can select the appropriate frequency of oscillation by adjusting RP1, the output drives an electromagnetic armature through the capacitor C2, and this circuit changes the output voltage into the small amplitude of mechanical vibration, and it drives the brush head to vibrate, clean, and massage the gum to promote the blood circulation and keep health.
