|20140037127||MAGNETIC MOTOR SYSTEM - A magnetic motor system for driving a loudspeaker voice coil. The system has first and second parts that define a volume for receiving a voice coil. The first and second parts each have a respective permanent magnet with first and second sidewalls that extend in a direction away from the volume. The first sidewall slopes in a direction towards the second sidewall as the sidewalls extend away from the volume. The first and second parts further have respective guide members for channelling lines of magnetic flux in a return path between the permanent magnets.||02-06-2014|
|20130056296||MASS LOADING FOR PISTON LOUDSPEAKERS - A diaphragm for a loudspeaker including a plurality of masses, each mass being substantially the same radial distance from the centre of the diaphragm, the plurality of masses being divided into two arrays, each array including one or more individual masses, wherein, in use, at a selected frequency, the pair of arrays act to produce a dominant bending moment, and, the centre of the diaphragm lies substantially on the axis of the dominant bending moment, wherein, the dominant bending moment is the bending moment produced by the combination of masses which has the greatest magnitude, if they produce more than one bending moment.||03-07-2013|
