Vibration actuator and electronic equipment

Abstract

A vibration actuator includes: a movable body which includes a stack formed by a magnet, a pair of magnetic cores and a pair of non-magnetic weights, is supported at both upper and lower sides of the movable body by a pair of leaf springs made of a magnetic material connected respectively to the pair of non-magnetic weights, and is operable to move vertically inside of a coil of a fixing body. The fixing body further includes a magnetic cylindrical body which is disposed outside of the coil, and has a length, the length being longer than a distance between upper and lower ends of the pair of magnetic cores and shorter than a distance between the pair of leaf springs.
