Abstract

An armature structure for an electrodynamic shaker comprises an armature support and an armature coil assembly mounted on the support. The coil assembly includes a cladding, or alternatively a spine, of a carbon fibre material. Preferably the carbon fibres extend generally longitudinally of the armature, that is to say in its direction of motion.
