Abstract
An inertial exciter () for an acoustic radiator (), and a loudspeaker incorporating an acoustic radiator and such an exciter. The exciter has a massive member (); a coupler () adapted for attachment to the acoustic radiator () and adapted for relative movement with respect to the massive member (); a motor for effecting relative movement of the coupler with respect to the massive member; and a suspension () for supporting the massive member relative to the coupler. The suspension () acts in a plane generally passing through the center of mass of the massive member, thereby reducing any moment acting on the suspension. Also disclosed is a loudspeaker exciter assembly () that has a base plate () for attachment to an acoustic radiator in a non-repeatedly engageable manner, and an exciter () attached to the base plate () in a repeatedly engageable manner; and a loudspeaker incorporating such an exciter assembly.
