Abstract
Disclosed are embodiments of magnetic virtual springs for haptic systems. In an embodiment, a haptic system comprises: a magnetic housing having a surface with a surface profile; a mechanical spring system disposed in the housing, the mechanical spring system including one or more mechanical springs; a mass disposed within the housing and mechanically coupled to the mechanical spring system, the mass including or coupled to a magnet, the surface profile causing a magnetic force component to be generated in at least one direction that varies with the magnet position, the magnetic force component combining with a mechanical force component provided by the mechanical springs.
