Abstract
A voice coil motor with extended and stabilized travelling distance for lens-focusing includes a housing, a first spring, a carrier, a second spring, and a base. The first and second springs, diametrically apart, are connected between an inner surface of the housing and a side of the carrier. The base includes an insulating base plate on the second spring and coupled to the housing, and a metal connecting member on a side of the insulating base plate and welded to the second spring, providing a reliable connection to the base. The risk of the second spring accidentally falling off is reduced.
