frequency generators. This audio frequency generator is a triggered signal generator. When a positive pulse of about 6 volts (minimum) is fed to the circuits input , a modulated audio signal comes out of the output. The signal pattern is similar to a bird’s chirp. The pulse width of the trigger signal must be a minimum of 2.5 miliseconds.

Audio Tone generator circuit using 555, 741 IC

https://mechatrofice.com/circuits/audio-tone-generator

The below circuit consists of an astable multivibrator using a 555 timer IC. It generates a continuous square wave output. The circuit has an oscillation frequency about 670-680 HZ. The audio frequency of the circuit can be changed to wide ranges by varying the values of any of the resistance R1, R2 or the capacitance C1.
