Simple Audio Amplifier using 555 Timer IC
https://circuits-diy.com/simple-audio-amplifier-using-555-timer-ic/
The simple Audio Amplifier circuit appears in the above schematic. Control PIN 5 of 555, has been used here which is commonly kept grounded through a 0.01uF capacitor. Control PIN 5 is the purpose of 2/3Vcc inside the 555 timer IC, so we can change this 2/3Vcc voltage through this PIN.

Figure 1 shows the input and output signals of the 555 timer as they are arranged around a standard 8 pin dual inline package (DIP). Pin 1 - Ground (GND) This pin is connected to circuit ground. Pin 2 - Trigger (TRI) A low voltage (less than 1/3 the supply voltage) applied momentarily to the Trigger input causes the output (pin 3) to go high.
