Abstract
A voice coil motor in a camera module with a means of being mounted robustly on a base comprises a casing and the base. The casing is hollow, the casing comprises a top surface and a side wall around the top surface. The base comprises a base portion and projections, the base portion being in contact with the side wall of the casing and engaged with the casing to form a cavity. The side wall is provided with recesses external to the cavity to accept the projections, the projections lending structural reinforcement to the casing.
