Tone generator circuit using 555 timer

Bird sound generator, Ambulance Siren Generator

 

These are some circuit diagrams of the sound generators. Sounds are like Bird sound, Ambulance siren, Beep Horn, and other different types. Use 9 to 12v Dc supply and components value should be the same as suggested in the diagram because any variation of components value can change the sound type.

By some changes of values of some components as given below in the diagram, you can produce many different types of sounds. Use a medium-size speaker, These circuits can be useful for the making of an Alarm, Doorbell or other warning indicators.
