Abstract
An apparatus for creating haptic simulations is provided. The apparatus includes a body that defines an inner cavity, and a pair of connectors positioned adjacent to ends of the body. A wire electrically connects the connectors and is wound around a first portion of the body in a first direction and wound around a second portion of the body in an opposite direction. A ring magnet is secured to an outer surface of the body. An armature magnet is slidably positioned within the inner cavity aligned with the ring magnet due to its magnetic pull. When a current is driven through the wire, simultaneous push and pull forces are created, causing the armature magnet to oscillate within the inner cavity to create vibration. When a magnitude of the current driven exceeds a threshold, the armature magnet impacts a stop of the inner cavity to create a “click” stimulation.
