Abstract: A voice coil motor for driving a liquid lens and a lens assembly having a voice coil motor, where the voice coil motor includes a plurality of sub motor parts. The sub motor parts can be independently controlled. The sub motor part includes an unmovable part, a movable part, which can move along an optical axis direction relative to the unmovable part, a connection elastic piece, coupled to the liquid lens and the movable part, where when a force is applied to the movable part in the optical axis direction, the movable part drives the connection elastic piece to squeeze the liquid lens.
