ABSTRACT:
A loudspeaker is provided with a viscous magnetic fluid suspension for the voice coil, rather than the corrugated disk suspension that is conventionally used. Specially designed vent passages are formed in the magnet assembly, in order to prevent internal pressure build-ups, or subatmospheric conditions, that could cause the magnetic fluid to be blown out of the magnetic gap, in which the voice coil is located. The vent passages permit use of a relatively low viscosity fluid to be used for the fluid suspension. A fluid viscosity of about fifty (50) centipoise is contemplated.
