Vibrating linear actuator and portable information apparatus having the same

摘要

A slim and efficient vibrating linear actuator includes a stator which sandwiches a coil generating vibrating magnetic field, and a first teeth section and a second teeth section. A mover, including a permanent magnet, is linked to the stator by elastic bodies and energized substantially to a midpoint between the first and second teeth sections. When the mover faces both of the first teeth section and the second teeth section, electric current is supplied to the coil, and when the mover faces only one of the first teeth section or the second teeth section, no electric current is supplied to the coil. This structure allows the vibrating linear actuator to be slimmed down and operate efficiently. A portable information apparatus employing this actuator can be slimmed down and work efficiently.
