Simple Basic Audio Amplifier Circuit Using NPN Transistor.


This Is A Transistor Audio Amplifier Circuit. It Is A Simple NPN Transistor Amplifier, That Shows You the Basics of Audio Amplifier Design. Using Just A Little Bit of Electronic Components, All You Need to Make It, (Transistor, Capacitor, Battery, Resistance, Speaker, Audio Jack) And Congratulations! You Make Your First Audio Amplifier.

Things Needed for the Audio Amplifier Circuit:


-C5611 Transistor NPN. (Any High Power NPN Transistor)
-3.5mm Audio Jack. (You Can Use an Old Headphone Jack Audio)
-3.7V Powers Supply. (Here I Have Used A Lithium-ion (Li-Ion) Battery 18650,3.7v)
-A Speaker. (Any Small Speaker Is Enough)
-An Audio Output Device. (I Have Used the Laptop Device for Sending the Audio Signal)
-1kΩ resistance. (You Can Use 5kΩ Potentiometer)
-5.6uF Capacitor. (You Can Use 1uF to 10uF Capacitor Range)
