A liquid containing magnetic particles in which the moving parts of a bass/mid/treble drive unit.are submersed to provide cooling of the voice coil and damping.
a colloidal suspension of magnetic nanoparticles in a carrier liquid
a fluid with magnetic particles in it, and if the fluid is exposed to a magnetic field, all the magnetic particles will align with the field lines, and making the fluid much more dense
a liquid which contains incredibly small pieces of a magnetic substance
a special solution of magnetic particles in a colloidal suspension whose flow can be controlled by magnets or magnetic fields
a stable colloidal suspension of ferromagnetic mono-domain particles in a liquid carrier
a stable colloidal suspension of sub-domain magnetic nano particles in a liquid carrier
a stable suspension of submicron size magnetic particles in various carrier liquids
A Magnetic oil, usually applied around the voice coil of a tweeter. Its advantages are that it increases short-term power handling by conducting heat from the voice coil to the magnet structure and it damps the tweeter's Fs, allowing it to work better with the crossover.
An emulsion containing metal particles, used to conduct heat away from a speaker's voice coil.
A fluid in which fine particles of iron, magnetite or cobalt are suspended, typically in an oil. A ferrofluid is superparamagnetic and can create liquid seals held in position by magnetic fields. One application of ferrofluids is to keep dust off of the drive shafts of magnetic disk drives. Ferrofluids were invented by NASA as a way to control the flow of liquid fuels in space.
A liquid composed of nanometer-scale magnetic particles suspended in a carrier fluid that responds to a body-force which is proportional to the gradient of the applied magnetic field. In other words, ferrofluids do not develop a yield strength such as MR fluids. Rather, they remain liquid but experience a force that moves them toward regions of higher magnetic field strength.
A magnetic and thermally conductive liquid used to maintain a driver's cool operating temperature by conducting heat from a voice coil to the magnet structure. This is used in all Mirage tweeters.
A ferrofluid is a liquid that becomes strongly polarised in the presence of a magnetic field. Ferrofluids are composed of nanoscale ferromagnetic particles suspended in a fluid, usually an organic solvent or water. The ferromagnetic nano-particles are coated with a surfactant to prevent their agglomeration (due to van der Waals and magnetic forces).
