Abstract:
A voice coil motor device for positioning is disclosed. The voice coil motor device for positioning includes a fixed element, a moving element and a connector. The moving element is movably disposed on the fixed element. One end of the connector is connected with the fixed element and the other end of the connector is connected with the moving element. A piezoelectric element is disposed on the connector or deposed between the moving element and the fixed element. The piezoelectric element can be deformed with the movement of the moving element to generate a displacement signal of a moving element. The positioning of the voice coil motor can be achieved precisely basing on the judgment on the displacement signal of the moving element generated with the movement of the moving element by the piezoelectric element.
