Audio Frequency Generator Circuit. 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.
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.

audio generators. frequency generators. MAX038. High frequency waveform generator is very useful in electronic experiment and design. This circuit generate sine wave oscillation, but actually we can modify the circuit to generate triangle or square wave function. The core of this waveform generator is MAX038. This integrated circuit chip gives complete …
How to make a Frequency Generator:

To put the set the frequencies I use my computer. I use the 1/8" stereo jack into my sound card, making sure the input volume is on low. Use a Sound generator program and match the tones. Make sure the sound wave is set to square. It takes time to get it right but it works. On a good day it takes me 1 hour and half to make the whole thing.

After assembling the circuit on the PCB, upload the source code (freq_gen.ino) to Arduino board. Disconnect Board1 from computer and connect it to 9V supply across CON1. You can view the generated frequency value on LCD1 by opening switch S1, or check different signal waveforms on the serial plotter by closing S1.
Audio Frequency - an overview | ScienceDirect Topics
https://www.sciencedirect.com/topics/engineering/audio-frequency
An audio frequency generator outputs frequencies in the range 20 Hz to 20 kHz. The sounder output is toggled with a delay between each operation determined by the frequency required, as in the BUZZ1 program. For example, for a frequency of 1 kHz, a delay of 1 ms is required, which is 1000 instruction cycles at a cycle time of 1 μs.
Signal Generator - Audio Amplifier Design

Sometime around 1982 I designed a variable frequency audio signal generator, called the AFG/3, with a range from 10Hz to 100kHz and sinewave, squarewave and toneburst outputs. There were switched ranges from 0-3V down to 0-3mV, and a constant 600R output impedance.
