An electrodynamic shaker apparatus is disclosed for providing shaking and/or vibrational motion. The shaker includes armature and stator assemblies as well as a distributed spring assembly. The shaker apparatus of the present invention is robust, supports increased off-center loads, and has a low profile such that it may be easily placed under an item of furniture in order to impart vibrational motion in response to electrical signals from a variety of sources.
