Abstract
A haptic feedback device () comprises a stationary frame (); a carrier () configured for at least one degree of motion relative to the stationary frame; a user interface () mounted on the carrier and configured to receive a human impulse; a set () of pole pieces; and, a suspension system (). The haptic actuator () comprises a first pole piece () mounted to the stationary frame (); a second pole piece () mounted to the carrier (); and, an electromagnetic coil () carried by one of the first pole piece and the second pole piece. The first pole piece and the second pole piece are separately mounted to define an air gap () therebetween in a first direction when the electromagnetic coil is not energized, the first direction corresponding to the at least one degree of motion. The suspension system () is mechanically separated from both the first pole piece () and the second pole piece ().
