An axially actuating device having an elastic joining portion is provided, which is used for carrying an object and actuating the object to move axially, and comprises a fixed portion, a moving portion, and a joining member. The joining member is used to combine the fixed portion with the moving portion, such that the fixed portion and the moving portion are axially coupled with each other. Moreover, the fixed portion and the moving portion are respectively a fixed magnet and a coil, such that when a current is applied to the moving portion, the moving portion generates a relative displacement with respect to the fixed portion according to the current, so as to provide an axial displacement. Meanwhile, the moving energy is generated due to the repulsive interaction of the magnetic field, and thus a shock proofing efficacy is also provided.

A disclosed lens module includes a zooming actuator, a cam, an auto-focusing actuator and at least two sets of lenses. The cam is coupled to and driven by the zooming actuator. The camhas at least two tracks. The auto-focusing actuator is coupled to and moved along one of the tracks of the cam. One of the sets of lenses is coupled to and driven by the auto-focusing actuator. Another one of the sets of lenses is coupled to the another track of the cam.

A micro electromechanical differential actuator is comprised of a suspension arm structure and/or a bridge structure to make a two-degree-of-freedom and bi-directional motion. The actuator support base can make out-of-plane or in-plane vertical and horizontal motions. The invention is applicable in optical micro electromechanical devices such as optical switches, variable optical attenuators, optical tunable filters, modulators, tunable VCSEL's, grating modulators, micro displays, and RF switches.
