Abstract
An apparatus includes a load and a first armature. A first lever mechanically couples the first armature and the load. Motion of the first armature causes the first lever to pivot about a first pivot axis. The apparatus also includes a second armature and a second lever that mechanically couples the second armature and the load. Motion of the second armature causes the second lever to pivot about a second pivot axis. At least one stator is provided for creating magnetic flux for the first and second armatures to interact with, thereby to drive motion of the load. The apparatus also includes a coupling mechanism that couples the first lever and the second lever. The coupling mechanism is arranged to encourage common mode oscillation of the first and second levers and inhibit differential mode oscillation of the first and second levers, thereby to inhibit rocking of the load.
