Simple siren circuits are an important part of electronic security devices nowadays. Now place the ldr in light. Sound output will be severely reduced if any objects are in front of the speaker.

So the sound output obtained from the speaker will be like a siren.

This requires two resistors r5 feedback resistor and r4 connected to u2b as shown in the circuit diagram. Surf simulator circuit diagram. The sound produced imitates the rise and fall of an american police siren. The above given was a simple siren circuit diagram using transistors which can be built and implemented by means of low cost.
