Abstract
An auto-focusing lens of a camera includes a lens unit (), a permanent magnet () being fixedly mounted around the lens unit to move with the lens unit, a first coil seat () arranged on a first side of the magnet with a first winding () wound thereon, and a second coil seat () arranged on a second side opposite to the first side of the magnet with a second winding () wound thereon. The first and second windings and the first and second coil seats are provided for establishing magnetic fields when electric currents are applied to the first and second windings. The magnetic fields interact with the magnetic field of the permanent magnet to drive the lens unit into movement between its front focus point (A) and its rear focus point (B).
