Rain Sound Generator Using NE555 PCB

Posted on Feb 4, 2014

The circuit diagram shows a timer 555 based rain sound generator. The circuit requires a 9V dc power supply and can be fed from a 9V battery. The loud speaker for producing sound is of 0. 5W 8ohm speaker. The circuit will readily generate a rain like sound whenever the circuit fed by a 9V supply. The rain generator has two sections one is a UJT rela

xation oscillator. This oscillator is build upon the uni junction transistor 2N2646. This oscillator produces a fixed frequency as per the value of C1. This continuously resets the 555 because the UJT oscillator output is connected to the reset pin of the NE555. On the other hand, the 555 IC works itself as a astable multivibrator. This process result in the generation of a rain like sound from the speaker.
