Abstract: The current document is directed to non-linear haptic actuators that use a rotor, rotor-suspension, and spring subsystem to efficiently generate vibrational forces in various types of devices and appliances in which the non-linear haptic actuators are incorporated. Non-linear haptic actuators can be designed and manufactured to be more space efficient than unbalanced-electric-motor and linear-resonant vibration modules and, because most of the frictional forces produced in unbalanced-electric-motor and linear-resonant vibration modules are eliminated from non-linear haptic actuators, non-linear haptic actuators are generally more power efficient and robust than unbalanced-electric-motor and linear-resonant vibration modules.
