Abstract

The goal of this invention provides a shaking electromagnetic actuator. It is thin and compact, and generates big driving force. The resolving method of this invention comprises a chassis, a movable component, and a fixed component. The movable component includes a permanent magnet 120, and an output lever 130. Using a shaking shaft (an output linkage shaft) 132 as a center that plays a role as a support that is freely shaking. The fixed component possesses an exciting coil 110. The structure of the movable component allocates the shaking shaft at the surface center of a permanent magnet plate with flat shape. The shaking plane formed by the movable component is parallel to the permanent magnet, and the thickness-direction is magnetized. The coil of fixed component is wounded in a flat plane faced to the surface of the permanent magnet plate. The permanent magnet is divided into four magnetic areas allocated at the peripheral direction of the shaking shaft. The polarity of the four magnetic areas is alternatively reversed. The hollow coil possesses two straight lines, they mainly make the currents flow at an opposite and parallel direction. On one aspect, it mainly makes the straight line face the surface of the permanent magnet plate. On the other aspect, it embraces the shaking shaft to make the straight line face the surface of the permanent magnet plate. In addition, it is allocated at the crosscut neighboring direction facing the two magnetic areas.
