AUTO-FOCUSING LENS ASSEMBLY WITH ENHANCED DRIVING POWER FOR MOBILE APPARATUS

摘要

PURPOSE: An automatic focusing lens assembly for a mobile device in which driving force is improved for reducing the size of the entire automatic lens assembly is provided to drive lens barrel easily by improving the driving force by the operation of a magnet and driving coil. CONSTITUTION: An automatic focusing lens assembly for a mobile(100) includes a lens barrel(110) and a driving source(130). The lens barrel accommodates the lens unit. The lens unit takes a picture of the subject through an image sensor. The driving source is protruded into the form in which the outer side upper end of a driving coil(140) is extended upwardly. The driving source moves the lens barrel by the driving force through the interaction of the magnet and driving coil along the optical axial. The inside diameter of one is comprised among the magnet or the driving coil at least it is smaller than the maximum out diameter of the lens barrel.
