Abstract
A recoilless voice coil actuator and method having flexures connected to both the magnet and the voice coil allowing independent movement of both the magnet and the voice coil in the direction of actuation. The stiffness or resistance to movement of the flexures is selected so that the natural frequencies of the magnet and the voice coil along the direction of actuation are substantially the same.
