sound generator

Posted on Feb 4, 2014

The construction of this quite complicated circuit will be awarded with the joy of generating almost unlimited sound effects. The circuit can produce different sounds like the heavy chopping of a helicopter s blades up to the fine chirping of a bird. A vibrato generator (T1 and T2) modulates a tone generator (T3 and T4). The frequency of the vibr

ato generator can be varied through P2. A second vibrato generator is also built (T6. T10) and has the same function as the first one described. The noise sound is produced by T6 while transistors T7 and T8 amplify the generated noise sound. The potentiometers P3, P8 and P4 influence the amplitude of the generated signal and create the desired sound effect. Potentiometers P5, P9, P10 produce the desired noise envelope and strength. The mixed tone and noise signals appear at the emitter of T14. Experimenting with different potentiometer settings will certainly produce hours of enjoyment and lots of unique sound effects.
