One Transistor Audio Amplifier Circuit Diagram. A transistor is a three terminal semiconductor device and the terminals are e emitter b base c collector the transistor can work in three different regions like active region cutoff region saturation region. This circuit can drive 8 ohm loud speaker and produce considerable sound.

Transistors work as an amplifier while they work in the. This circuit can drive 8 ohm loud speaker and produce considerable sound. We can use maximum 9 6 this why we use 8 amperes.

The simple transistor amplifier circuits are commonly used where small audio amplification is required.

In this audio mixer circuit transistor 2n2222a is the heart of the circuit. The simple transistor amplifier circuits are commonly used where small audio amplification is required. There are also high power transistor amplifier schematics are available but it is easy to use ics as compare to transistors if you want to make a high power audio amplifier circuit. The output is provided across a 22uf capacitor.
