Abstract:
1. An oscillation structure applicable to a micro actuator, the oscillation structure comprising: a pair of torsion bars disposed in a first axis perpendicular to a second axis; a first frame coupled to the pair of torsion bars wherein the pair of torsion bars is disposed in an outer periphery of the first frame along the first axis; a second frame disposed inside the first frame; an oscillation body disposed inside the second frame; at least four first connection members coupling the first frame to the second frame therebetween, wherein a pair of the first connection members of the first connection members is aligned to the first axis in a collinear manner; at least four second connection members coupling the second frame to the oscillation body therebetween, wherein a pair of the second connection members of the second connection members is aligned to the first axis in a collinear manner to allow the first frame, the second frame and the oscillation body to rotate about the first axis by the pair of torsion bars.
