How Do Heart-Shaped Vinyl Records Work? (2024)


If you’re familiar with the world of vinyl records, then you’ve already heard about heart-shaped vinyl. For those who haven’t, just know that records come in many different shapes, as long as these shapes fit on a turntable and rotate without any issues.

It’s also important to note that most of these shaped records are 45’s, or singles, as they usually carry less music than your standard LP’s.

Heart-shaped records have existed for a while now, but with the recent resurgence of the vinyl “aesthetic”, have become even more popular.

Everyone can pretty much guess how these records are made – same way as any other record, just with a different kind of mold.

But how heart-shaped vinyl works is a different topic entirely.

Today I’m going to go over how heart-shaped vinyl works. Keep in mind that there will be some physics involved, as well as some chemistry (no pun intended). But I’ll keep it light so everyone can understand it just as well.

Heart-Shaped Vinyl: The Electric Part

First, to understand how a vinyl record produces sound, we need to understand the electrical components that go into it.

An important concept is that of electro-magnetic induction.

This simply refers to when a magnet moving inside a coil of wire generates an electric current. This electric current also reflects the specific movement of the magnet.

Next, if you look at the grooves of a heart-shaped vinyl record under a microscope, you’ll notice it has a rough texture with bumps and dips. When the turntable needle (or stylus) goes over the record, these bumps and dip cause it to move up and down.

Now here’s where we combine the first part with the second part.

If you remember, the magnet moving generates a proportional electric current.

And – the turntable needle, aka the magnet, moves up and down depending on the bumps and dips on a vinyl record.

So depending on the song that a heart-shaped vinyl record will play, it will have unique bumps and dips which, when the magnet goes over them, results in the generation of unique electrical signals.

These electrical signals, or sound waves, represent the original audio signals from the song.

Once the needle generates these signals, they get amplified by a phono preamplifier, which (quite surprisingly) amplifies the signal. The amplified signals then get sent to the speaker, where they get converted back into sound waves for your enjoyment.



Not too bad, right?

Anyway, that’s pretty much how heart-shaped vinyl records (and all vinyl records) work.

Can vinyls be different shapes?

Yes, vinyl records can come in different shapes, including standard round discs, specialty shapes like hearts or triangles, and any other shape that would fit on a turntable.

How do custom vinyls work?

Custom vinyl records are made by cutting grooves into blank discs based on audio files provided by customers, allowing them to create personalized records with their own music or recordings.

Can you press a custom vinyl?

Yes, you can press a custom vinyl record using specialized equipment that cuts grooves into blank vinyl discs to produce playable records.
