ABSTRACT:
A linear actuator has at least one driving unit having a piezoelectric device (11), a yoke (19) fixed on the piezoelectric device (11) and an electromagnet (20, 21) provided on the yoke (19) and a moving member (23) made of magnetic material such as ferrite disposed under the electromagnet (20, 21) with a small gap therebetween; and linear movement of the moving member is produced by repeating expansion and subsequent contraction of the piezoelectric device (11) and simultaneously exciting and subsequent demagnetizing of the electromagnet (20, 21).
