Abstract
An oscillation structure of micro actuator is described. In the oscillation structure, a pair of torsion bars is disposed along a first axis perpendicular to a second axis. The first frame is connected to the pair of torsion bars wherein the torsion bars are disposed on the outer periphery of a first frame along the first axis and a second frame is disposed inside the first frame. Each of the first connection members connects the first frame to the second frame therebetween, and each of the second connection members connects the second frame to the oscillation body therebetween such that the first frame, the second frame and the oscillation body are allowed to rotate about the first axis by the torsion bars as a structure assemblies at an identical angle. The oscillation structure effectively reduces the dynamic deformation of micro actuator.
