How to Stop Door Opener Sound with 2 parts

About :

We have shown a simple but definite method for eliminating the annoying buzzing sound in door automatics. Door automatics work with alternating current. Alternating current pulses change the direction of the magnetic field on the coil 50 times per second. This situation vibrates the mechanism opposite the coil with a frequency of 50 Hz like a speaker. This circuit we have made eliminates the incoming frequencies and makes it full dc and the sound is eliminated. The diode used is 1.5 amps and the capacitor is 35 volts 330 uf. We hope it will be useful.
