Abstract

According to a first aspect of the invention there is provided an inertial exciter (40) for an acoustic radiator (42), the exciter comprising a massive member (44); a coupling member (46, 56) adapted for attachement to the acoustic radiator (42) and adapted for relative movement to the massive member (44); a motor for moving the coupling member (46, 56) relative to the massive member; and a suspension (60) for supporting the massive member; and a suspension (60) for supporting the massive member relative to the coupling member. The suspension (60) acts in a plane generally passing through the centre of mass of the massive member, thereby reducing any moment acting on the suspension means. A second aspect of the present invention consists in a loudspeaker exciter assembly (70) comprising a base plate (86) for attachement to an acoustic radiator in a non-repeatedly engageable manner; and an exciter (40) attached to said base plate (86) in a repeatedly engageable manner.
