Abstract: An optical element driving mechanism is provided and includes a fixed assembly, a movable assembly, a driving assembly and a stopping assembly. The fixed assembly has a main axis. The movable assembly is configured to connect an optical element, and the movable assembly is movable relative to the fixed assembly. The driving assembly is configured to drive the movable assembly to move relative to the fixed assembly. The stopping assembly is configured to limit the movement of the movable assembly relative to the fixed assembly within a range of motion.

Abstract: A waterproof click pad device includes a click pad, a frame and a waterproof unit. The frame surrounds the click pad and surrounds an axis passing through the click pad. The waterproof unit is transverse to the axis and is in sheet form. The waterproof unit includes a frame adhesive member surrounding the axis and adhered to the frame, a first non-adhesive member surrounding the axis, connected to an inner periphery of the frame adhesive member and spaced apart from and located above the frame, a second non-adhesive member surrounding the axis, connected to an inner periphery of the first non-adhesive member and spaced apart from and located above the click pad and the frame, and an plate adhesive member connected to an inner periphery of the second non-adhesive member and adhered to the click pad.
