1. A lens module, comprising:
a lens comprising a fluid and a cavity to accommodate the fluid;
a first mover frame supporting the lens, the first mover frame comprising a pressurizing portion disposed to face a pressurized region of the fluid;
a magnet disposed at the first mover frame;
a coil unit comprising coils disposed to face the magnet in a first direction perpendicular to an optical axis;
a second mover frame disposed to face the first mover frame in a second direction in parallel to the optical axis, with the magnet interposed therebetween, the second mover frame supporting the magnet together with the first mover frame; and
a driving controller configured to control supply of current to the coils such that the pressurized region of the fluid is pressurized by the pressurizing portion of the first mover frame through an interaction between the coils and the magnet,
wherein the lens comprises:
a receiving body including the cavity to accommodate the fluid;
a movable membrane disposed to store the fluid together with the receiving body; and
a pressurizing frame disposed between the movable membrane and the first mover frame, the pressurizing frame being configured to apply a driving force from the first mover frame to the pressurized region of the fluid, and
wherein the pressurizing frame comprises:
a driving frame disposed under the movable membrane, the driving frame having therein a hollow portion; and
a protrusion protruding outwards from a lower portion of the driving frame, the protrusion being disposed between the pressurizing portion of the first mover frame and the pressurized region in the second direction.
