Ferrofluid display cell bluetooth speaker

Heads up, there is some new tech in town and this one might just blow your mind. Feast your eyes on this bluetooth speaker that moves to the sound of music using Ferrofluid, a material developed by NASA in the 1960s that was used as both spacecraft fuel and sealing material. Designed and created by DAKD Jung, the impressive project demonstrates how sound influences the Ferrofluid by controlling the strength of the electromagnet inside and the shape of the magnetic field. The creator revealed that he programmed the device to react to the volume of each range. Join us in taking a closer look at this incredible device.

3D printed with a design that had no choice but to let sound escape upwards, the Ferrofluid responds to music through a device that operates an electromagnet device using ‘MSGEQ7’, a module that separates the sound range. Since Ferrofluid adheres well to glass, the glass required special treatments and the Ferrofluid suspended in clear liquid to gain the effect. Inside, the speaker’s enclosure was customised to fit the speaker case then sealed so that the passive radiator can operate. Additionally, DAKD Jung installed LED lighting to make this creation stand out. The result… a speaker that we would love to get our hands on and try out for sure. Hats off to DAKD Jung for this epic creation.

Forget KRK Rokit and Yamaha Studio speakers, the Ferrofluid display cell bluetooth speaker is what we want to see and hear more of. Check below to see the YouTube video and how the speaker was created below and the speaker placement examples. Witness the interesting process, from start to finish, and check out the Ferrofluid in action at the end of the video. Let us know, if you had one of these, what would be the first track you would play on it? For the latest tech news, click here.

Bluetooth-колонка с визуализацией мелодии при помощи ферромагнитной жидкости

Dakd Jung — художник из Кореи, собрал музыкальную Bluetooth-колонку, которая использует ферромагнитную жидкость для визуализации мелодии.

Корпус колонки изготовлен при помощи 3D-печати, а внутри, кроме Bluetooth-модуля, усилителя звука и динамиков — находится освещенный светодиодами стеклянный контейнер с ферромагнитной жидкостью и электромагнит, мощность которого меняется в зависимости от темпа музыки.
Управление электромагнитом осуществляется контроллером Arduino Nano, пропорционально громкости в определённом частотном диапазоне воспроизводимой музыки, получаемой с модуля графического эквалайзера MSGEQ7.

This DIY Bluetooth speaker’s magical ferrofluid display reacts to the music

Ferrofluid is a special kind of liquid full of ferromagnetic particles, so it reacts to magnetic fields. Dakd Jung built a beautiful Bluetooth speaker that features a ferrofluid display driven by an Arduino.

This Bluetooth speaker has a gorgeous minimalistic 3D-printed enclosure that would look great on any bookshelf. But it is the ferrofluid display that makes the speaker special. A glob of ferrofluid floats inside of a glass reservoir mounted front-and-center on the speaker. That ferrofluid moves to the music playing through the speaker, providing a mesmerizing visualization. There is even a dial that lets the user adjust which part of the sound frequency that the ferrofluid responds to.

The ferrofluid is able to react to the tunes thanks to an electromagnet placed behind the glass reservoir. An Arduino Nano board controls the power going to that electromagnet proportionally to the volume in a specific frequency range of the music playing. An MSGEQ7 graphic equalizer module isolates the desired frequency range. The Arduino monitors the voltage output from that module and uses it to control the voltage going to the electromagnet.

The result is that the ferrofluid jiggles and bounces along to the intensity of the music. If the user tunes the dial to low frequences, then the ferrofluid will react to the bass. If set to high frequencies, the ferrofluid will respond to treble. It is entrancing to watch and a very creative use of ferrofluid.

Awesome ferrofluid-filled speaker visualizes your music with alien-like goop

There are plenty of stylish, tech-heavy speakers doing the rounds in 2021, but not too many are quite like the speaker designed and built by Dakd Jung. A 40-year-old artist living in Ansan, South Korea, Jung has created an unusual speaker that harnesses the power of ferrofluid, a viscous magnetic oil invented by a NASA scientist in the early 1960s, to amazing effect.

Ferrofluid inventor Steve Papell imagined that the innovative substance — made of nanoscale ferromagnetic particles suspended in a carrier fluid — could be harnessed as a magnetized rocket fuel that would be easier to draw into a rocket’s engine in the absence of gravity. It has never been used this way, however. Engineers accomplished much the same goal using elastic sump tanks and aerosol propellants.

Instead, while ferrofluid has gone on to be used in genuine engineering applications (it’s utilized in computer hard drive rotary seals and as a contrast agent for MRIs), it has most notably gained a public second wind as a material used by artists to create otherworldly projects. With its strange, quivering spikes and gloopy, black appearance, ferrofluid looks about as close as the world will likely get to a real-life version of Marvel’s Venom symbiote.

Moving to the music

In the case of Jung’s speaker, he uses it — in conjunction with an electromagnet — to conjure up a speaker display that moves around in time to the music being played on it. Imagine the aliens from Arrival living it large at a rave and you won’t be too far off.

Jung told Digital Trends that he became interested in ferrofluid in 2015 when he bought a small ferrofluidic bottle toy from Amazon. “Its physical properties were really amazing,” he said. “I think it [struck me] because it was unfamiliar for a fluid, not a solid, to react to magnetism. Fluid mechanics is very beautiful.”

Jung calls himself an installation artist interested in kinetic and new media art. But he also studied and worked as an electrician and electronic engineer. His work, therefore, bridges what English novelist C.P. Snow once called “The Two Cultures,” with science and the humanities firmly seated in opposite camps. It’s an interesting blend of art and science.

Since finding out about ferrofluid, Jung has used it in multiple pieces of art — including an impressive ferrofluid “Pataphysical Pond,” in which the ferrofluid spreads out like a live oil spill or an ever-shifting Rorschach test. The idea for the speaker came to him when he was listening to music while playing with a ferrofluid display cell he had built. Absentmindedly, he manually began timing the electromagnetic pulses to match the music he was hearing.

“It was like dancing,” he said. “It looked fun.”

The 3D-printed speaker shell boasts a suitably 1960s retro-futuristic space age aesthetic that could comfortably fit among the props in a movie like 2001: A Space Odyssey. Its look was inspired, Jung said, by the work of German industrial designer Dieter Rams and the Japanese graphic designer Kenya Hara. “I like very simple things,” he noted. “I [wanted] to avoid the ‘LED show’ [look], which is often seen on other Bluetooth speakers.”

Inside the speaker shell are triple upward-firing speaker drivers, a Bluetooth module for connecting with an audio source, and a compact amplifier. There’s also a glass bottle containing the ferrofluid, some LEDs for illuminating it, and a mounted electromagnet, controlled via Arduino Nano, which coaxes the ferrofluid into reacting to the music played.

“The biggest problem with ferrofluid is that it is easy to stain the glass bottle,” he said. “To fix it, you need to keep the glass chemically very clean. It is then possible to make the glass surface superhydrophilic through a special coating. In addition, ferrofluid must be made not to oxidize for a long time because the main ingredient is oil.”

After he completed his initial prototype, Jung decided to share his speaker with the world. This, in turn, inspired his possible future plans to bring it to market. “I started making it for fun, but after posting it on my social media, [people were telling me to] ‘shut up and take my money,’” he said.

As a result, he’s now considering ways to develop the concept further, with an eye on eventually manufacturing a model he can sell. “We are trying to combine with various speaker types,” Jung explained. “We plan to create a device that can be used by connecting to a high-fidelity speaker rather than a Bluetooth speaker.”

Whatever form it ultimately takes, who wouldn’t want one of these? This is pretty much the definition of a party piece in every sense of the word.
