How Can Different Sounds Be Made When the Needle Touches the Record?

The needle rotating on the record starts with a slight crackle and then filling the whole room with music Is it impressive only to us, or is it quite normal for you? Moreover, the records in question Almost as thin as paper…

If you are one of those who are surprised by this situation, technology and art Let’s unravel together the mystery of records that unite us on a common denominator.

The example we will give at first will help you understand how plates work.

Let’s say you’re talking through a large tube with a balloon stretched over the end. This stretched balloon is attached to the pipe in question. It will vibrate when you speak. This vibration is the same vibration your eardrum makes to allow you to hear sound.

Let’s say you have taped a pencil to the balloon that will vibrate along with it, and you have a piece of paper in front of you. If you move the paper at a constant speed An image similar to the scribbles we see when recording audio will appear. That’s exactly how vinyl works!

What if we made a 3D line instead of a 2D line?

In the 1800s, some pursued this idea and He invented the gramophone. Think of Lady Gaga’s voice; sings into a horn, and this sound is recorded on a wax plate by a needle attached to the diaphragm. forming bumps and valleys being recorded.

Take this wax record and put it on a When you turn it into a metal record, Now you can have your own vinyl record. If everything is ok so far, let’s now take a look at how this record sounds, that is, how it plays.

The answer is to turn everything upside down.

Close-up of the record.

The record is spun and the needle is dropped into the groove, which moves through the bumps and valleys. vibrations of the original sound replays. Of course, modern pickups no longer use large horns.

We have stepped into the digital age and now cassettes, CDs and digital files there is. The diaphragm inside the microphone converts your sound waves into electrical signals. This electricity is a small force on magnetic tape. magnetization pattern creates.

When you play the tape, the pattern turns back into electricity and it comes out of the speaker as music. With CDs, things are a little more complicated.

This whole process is actually It’s based on a simple idea: Recording and replaying of sound, i.e. vibrations. Nowadays, every voice from Michael Jackson to Lady Gaga can be heard thanks to these miraculous technologies. whenever and wherever we want We can listen.

The answer is simpler than you thought, right? We will be waiting for your thoughts in the comments.
