Abstract
A device includes a frame and a haptic engine. The frame defines at least one flexure. The haptic engine includes a core attached to the frame, an attraction plate attached to the at least one flexure, and an electric coil wound around at least a portion of the core. The attraction plate is separated from the core by a gap. The electric coil, when energized, creates a magnetic field that causes a width of the gap to temporarily change. Some embodiments include a cushioning pad positioned within the gap or a layer of compliant material that attaches the attraction plate to the at least one flexure or the frame.
