Ferrofluid consist of a carrier liquid and small magnetic particles held in suspension by a surface active layer,a surfactant.The Ferrofluid can be fixed and would not flow under the external magnetic field. so we can improve the property of loudspeaker by filling the voice coil with the Ferrofluid. |
