WHAT ARE HEADPHONE DRIVERS?|| HOW ACTUALLY A HEADPHONE WORKS?
IF YOU ARE LOOKING TO PICKUP A HEADPHONE/EARPHONE THAT REALLY MATTER’S YOUR NEEDS, THEN IT’S VERY IMPORTANT TO KNOW HOW ACTUALLY A HEADPHONE WORKS.
THE KEY THING/KEY COMPONENT WHICH MAKES THE HEADPHONE WORK ARE THE DRIVER’S WHICH ARE PLACED INSIDE THE EARPHONE. LET’S DIVE HOW THE DRIVER’S GONNA WORK.
It’s Noteworthy plain engineering if you open the enclosure of any headphone. Inside the headphone enclosure there’s a little component. And that’s the DRIVER(driver assembly), and this is where all the magic happens.There are three sub parts inside the driver i.e. DIAPHRAGM , MAGNET , VOICE COIL
The part that produces sound in speakers is called the diaphragm . The DIAPHRAGM is vibrated or more correctly pulled back and forth at Rapid succession Which pushes on the air surrounding the headphones (disruptions and displacements in air creates sound waves) .This diaphragm Which is actually made out of plastic and produces the sound or music when it vibrates.
But you have a Doubt, how actually diaphragm is vibrating. Now if we remove the diaphragm from the assembly we’ll find two crucial parts
- VOICE COIL/THREADED COPPER WIRE
So the two parts that make a crucial role in the function of headphone are magnet & voice coil , because these two make a momentum for diaphragm to produce sound waves. First we have a magnet , Secondly we have what’s called a voice coil. It’s usually a threaded copper wire. That’s it..
HOW ACTUALLY A HEADPHONE WORKS? :-
When you play music through your headphones Jack , you are outputting a certain amount of electric pulse the way to your ears through the cable is running electricity back and forth now that current goes directly into this concentrated voice coil and as a result it creates an Electromagnetic field.
So a varying current of the audio signal Causes the voice coil to move up and down Alongside or rather inside the magnetic housing and since it’s attached to the diaphragm it pulls the diaphragm back and forth . The diaphragm pushes the Air back and forth and that creates sound waves which is how we hear. 🙂
