Simple Basic Audio Amplifier With BC547 Amplifier

Introduction:

In this article, we are getting to discuss an easy amplifier circuit with a BC547 transistor. Here you'll find the complete schematics and other more information. So thereupon being said let's start our article. And also i will be able to be talking about our sponsors UTSOURCE during this article.

How does the essential amplifier Circuit work?

This circuit works on the essential principles of the NPN transistors. The low amplitude Audio signal goes into the bottom of the transistor. Then the signal flows through the transistor's collector to emitter, as a result, the present will flow then the bottom gets a sign.

A capacitor is a connected serial with the bottom. This capacitor is employed to smooth the upper frequencies of the audio signal. (The signal which is coming from an audio signal) Then this signal amplifies through the transistor's collector pin.

First, we'll need a BC547 transistor. And these are the Pinouts of the BC547 Transistor.

Now take a hand tool then pre tin the Legs of the hand tool .

Now you'll need a 10K resistor. Then Connect the 10k Resistor with the Transistor's Collector and therefore the base Pin.

Now, you'll need a 100uF Capacitor. Then Connect the Capacitor's -ve Pin with Transistor's Base.

At next I would like to run the amplifier with the Android Device. So, we'll need a 3.5MM Headphone jack For this. From the Headphone jack, we'll get three wires. Right Channel, GND, LEFT Channel wires. Since we are making a Mono Amplifier we'll need just one Channel wire. it'd be the Left Channel wire or the proper Channel wire.

In my case, I'm using the proper Channel Wire.

Now Connect the Battery wires with the circuit. In Specifically connecting the Battery -ve with the Transistor's Emitter Pin.

If you remember then you'll see that we've missed the Speaker +ve wire. Now let's connect the speaker +ve wire. Connect the Speaker wire with the Battery +ve.

Here I even have connected the circuit with the Android Device then give the 9V Power supply. then I played free music from youtube and you'll see that the audio is playing through the Speaker so it means the Speaker, also because the Circuit, works perfectly.
