Patent ID: 7268503

Claim:
A vibration linear actuating device comprising a vibrating linear actuator and a driver for driving the actuator; the vibrating linear actuator including: (a) a mover having a permanent magnet magnetized in a radial direction; (b) a stator having a coil and facing the permanent magnet; and (c) an elastic body for coupling the stator to the mover and energizing the mover toward a center of the stator, the driver including: (d) a driving section having a switching element for powering the coil; (e) an output controller for controlling the switching element; and (f) a zero-cross detector for detecting a zero-cross point of back electromotive force (BEMF) generated in the coil and outputting a zero-cross signal, wherein the driver transmits the zero-cross signal to the output controller and powers the coil in one direction for vibrating the mover in corporation with the elastic body.
