Abstract
A lens module includes a printed circuit board, a lens component, and at least two electric conductors. The lens component includes a first lens and a microscope base, the first lens is formed on the microscope base, the microscope base is formed on the printed circuit board, and the first lens is electrically conductive and deforms under voltage. The first lens is electrically connected to the printed circuit board by the electric conductors. The printed circuit board outputs a voltage to the first lens through the electric conductors; the first lens deforms according to the voltage thereby changing a focal distance of light passing through the first lens. The disclosure also relates to an electronic device using the lens module. The lens module can has a zoom function and has a litter volume.
