What is Ferrofluid?

 The Magical Liquid That Makes Music Visible

Have you ever wondered what it would be like to see the shape of sound? At Volta Audio, we’ve turned that wild idea into a reality. We use a special material called ferrofluid to create speakers that literally dance to the rhythm of your music.

So, what exactly is this magical liquid that makes sound visible?

The Science Behind Ferrofluid

Simply put, ferrofluid is a special type of colloid. It's made of tiny, nano-sized magnetic particles evenly dispersed in a liquid, such as water, oil, or an organic solvent. These magnetic particles are so small that they won't settle out due to gravity, which is why ferrofluid looks just like an ordinary black liquid.

However, when a magnetic field is brought near it, ferrofluid shows its magic. Because the liquid is filled with magnetic particles, it is immediately attracted to the magnetic field, forming all sorts of strange, spiky patterns.

How Our Ferrofluid Speakers Work

In our ferrofluid speakers, we've cleverly integrated the ferrofluid with the internal workings of the speaker.

• The speaker generates a magnetic field: Inside a speaker, an internal coil creates a dynamic magnetic field when it's driven by an electrical current.

• The ferrofluid dances: As you play music, the audio signal becomes an electrical current, and that current drives the speaker to generate a magnetic field. The ferrofluid then responds to this changing magnetic field, forming unique, spiky movements that ebb and flow with the rhythm of your music.

This perfect fusion of sight and sound means your music experience is no longer just for your ears—it’s also for your eyes. You can see every beat, every high note, and every bass drop presented in the most visual way possible.

Why We Chose Ferrofluid

Ferrofluid was originally developed for NASA to control rocket fuel. Now, it's widely used in various high-tech fields, from medical devices to precision instruments. We've introduced it into our speaker design not just to create a unique product, but to redefine how you interact with music.

A Volta Audio ferrofluid speaker is more than just a player; it’s a sculpture that blends science, art, and design. It allows you to feel the music you love in a completely new way.
