Always interested in ways to improve the circuit if you’ve got any knowledge bombs.

-Generate a square wave with a 555 timer for instance.

-1st op amp is an integrator, converting square to triangle with lower amplitude 

- high pass filter inbetween the 1st and second op amp to remove DC offset.

-2nd op amp provides 21x gain

-3rd op amp is a voltage buffer to create low output impedance to ‘transfer’ more output voltage to 8 ohm ‘speaker’
