🧾 Components Used

Component	Description
Small Speaker (8Ω, 0.5–1W)	Main audio output unit
Audio Amplifier (LM386)	Boosts the audio signal
Capacitor (100µF, 10µF)	For sound filtering and gain
Potentiometer (10k)	For volume control
Aux Cable / 3.5mm Jack	To connect audio input
9V Battery / Power Bank	Power source
Small PCB or Breadboard	For assembling the circuit
Enclosure Box	For a neat and safe finish

⚙️ How It Works

1. The audio signal comes from the AUX cable.

2. The LM386 amplifier IC boosts the weak audio signal.

3. The amplified signal is sent to the 8Ω speaker, producing sound.

4. A potentiometer controls volume manually.
