How Does a Record Play 💿

Morning Music lovers!

Look at this close up of a record player…    

But how does that… make music??

Well, look, as you sing into a microphone, it vibrates this little copper coil thing:

The vibrations of the little copper coil are IDENTICAL to the vibrations of your voice.

So now imagine you tape a pencil to it, like this:

Look, it creates some wiggles!

Now, if you move the paper it creates a sound wave!

But what if that pencil was a needle etching grooves into the spinning disc?

(like the grooves in the GIF before)

You get a record!

That's the easy part!

You actually just do everything backwards…

You place the disk on the turntable and spin the disc at the EXACT same speed it was spinning before.

Then put the needle in the little groove…

And watch it vibrate the little copper coil, exactly like when you recorded!

But this time the copper wire is inside a speaker…

So we get… SOUND!
