摘要：PROBLEM TO BE SOLVED: To provide a voice coil actuator capable of reducing side force without changing the input quantity of magnets and the size of a motor. SOLUTION: In this voice coil actuator constituted of a center yoke 1, a pair of outer yokes 2 disposed on both sides with the center yoke 1 sandwiched, magnets 3 disposed at surfaces facing the center yoke 1 and facing the outer yoke 2 respectively, a pair of edge outer yokes 4 which magnetically joint both the edges of the respective yokes 1, 2, and an armature coil 6 inserted into two pairs of magnetic gaps constituted of the magnets 3 so as to be moved freely, the facing two magnets 3, 3 are shifted from each other in a vertical and thrust generating direction and disposed in the magnetic gap so that flux density distributed in the magnetic gap may have an arbitrary angle, and the magnets 3, 3 may become a linear symmetry with regard to the center yoke 1.
