Title: BRUSHLESS TWO DIMENSIONAL HAPTIC ACTUATOR
Abstract:
An eccentric magnet (400) rotates around a spool (402) under the influence of an electric field generated by a rotational coil (410) surrounding the magnet to produce haptic output by rotational vibration. The ends of the spool are connected to springs (414, 416), and linear actuating coils (406, 408) are disposed near the respective ends of the spool to cause the spool and, hence, the magnet rotating around it, to reciprocate, generating additional haptic output from the vibrations of the reciprocating motion.
