Ferrofluid speaker

Technology 8 Views. If you get very close to a pool of ferrofluid under the influence of a magnetic field, it almost looks like a 3D visualization you can see in a music video. This project may look like a lava lamp placed in front of a regular speaker, but it is surprisingly complicated. Artist Dakd Jung says that ferrofluid tends to adhere to glass, so the container had to be treated especially before it was filled with magnetic liquid. Then he had to build an electromagnetic device to manipulate the liquid to the sound of music. Finally, the entire equipment was placed in an elegant 3D-printed case.

NASA Technology Comes to Speakers: Ferrofluid

In order for a tweeter to optimally follow the fine and fast signals in its operating range, it is essential that its drive system is as light as possible.

At the same time the tweeter should also be highly resilient so that it can withstand excessive levels unscathed. The fluid establishes a thermal connection with the magnet system, allowing effective dissipation of the heat generated during operation. This results in increased resilience and constantly high sound quality of the tweeter. To ensure that it can continue to follow the music signal precisely, Magnat selects only low viscosity ferrofluids with optimum properties.

Ferrofluid for IT speakers

Live Chat. Need Help? Your shopping cart is currently empty. Ferrofluid - Amazing Magnets. Ferrofluid is a liquid made of nanoscale magnetic particles suspended in a carrier fluid. Each tiny particle is coated with a surfactant to inhibit clumping. This allows Ferrofluid to respond dramitcally to the influence of magnetic fields and change back when the magnetic influence is taken away.

Sony Magnetic Fluid Speaker

Liquids Research Limited produce ferrofluids based on ferrite and metal particles. A wide range of ready made and custom made magneto-rheological dispersions are also available. The philosophy of Liquids Research Limited is to supply specialist materials to industry who have an interest in developing new applications for these exciting materials. As Europe's leading manufacturer of magnetic colloids and related materials, Liquids Research Limited is uniquely placed to provide a comprehensive consultancy service for their clients. Apart from our standard catalogue products, Liquids Research have a number of client projects underway for development of tailored magnetic fluids, nanoparticles and magnetorheological dispersions. Much of the energy that is fed into a loudspeaker is wasted as heat. In order to dissipate some of the heat, heat sinks can be used. The heat generated by the voice coil will be partly transferred to the top plate of the speaker and the rest by air convection and conduction, which is not a very efficient process. The build up of heat within the voice coil causes it to expand and can lead ultimately to speaker failure.

Selecting the Correct Audio Ferrofluid

Adam Santa Maria. Category: Tech. The ubiquitousness of speakers is something of a double-edged sword. On one hand, you have a plethora of reputable, high-quality offerings to choose from, and on the other hand, the entire space is watered down by an even greater amount of mediocre products.

Sound box with dancing ferrofluid allows you to “see” the music

Ferrofluids, as the name implies, are liquids that respond to magnetic fields. They were originally developed for use by NASA as rocket fuel but are available to the general public now for anyone who wants to enjoy their unique properties. For [Dakd Jung], that meant building a special chamber into a Bluetooth speaker that causes the ferrofluid inside to dance along with the rhythm of the music. The project includes two speakers for playing the actual music that point upward, and everything is housed inside of a 3D-printed case. There were some additional hurdles to overcome as well, like learning that the glass needed a special treatment to keep the ferrofluid from sticking to it. Being able to listen to music or podcasts on a portable speaker, rather than the tinny internal speakers of a phone or laptop, is the sort of thing you think you can live without until you get used to having higher quality sound easily and in every place you go.

Speaker Asylum

For anyone as fascinated with this substance as I am, here [0] is a YouTube video of someone making it 'from scratch'. It's a very detailed explanation, and includes some comparisons of the outcome VS commercial ferro fluids. There's so much great content on his channels. When I first saw many of his videos, I was like: "damn, this dude has access to all sorts of chemicals, radioactive stuff, I bet he lives in Texas or Mexico". Then I learned that he lives in the same city as me. When I originally found his channel I thought he might be too young to take any sort of seriously, but he handles being that young pretty well. A model for others I think.

In this absolutely stunning example Seung Hoon Jung has built a bluetooth speaker with integrated ferrofluid display. The technical aspects of this are pretty interesting but mainly it has to be said that their ability to wrap everything up in such a deceptively simple looking package is very impressive. Senior Editor for Make: I get ridiculously excited seeing people make things. I just want to revel in the creativity of the masses! My favorite thing in the world is sharing the hard work of a maker.

Thankfully, there are startups like Van der Waals, who have made one of the coolest speakers I have seen in some time. The name ferrofluid was introduced, the process improved, more highly magnetic liquids synthesised, additional carrier liquids discovered, and the physical chemistry elucidated by R. Rosensweig and colleagues.
