A miniature lens focusing mechanism includes a lens holder (20), at least one winding element (30) surrounding the lens holder (20), at least one elastic element (50) connected to the lens holder (20) and the at least one winding element (30), and at least one magnetic element (40). When a current is supplied, the current is transmitted via the elastic element (50) to the winding element (30), so that an acting force is produced between the winding element (30) and the magnetic element (40) to displace the lens holder (20) and accordingly, achieve the function of auto-focusing.
