  • Publication number: 20130293969
    Abstract: A miniature lens auto-focusing structure includes a housing having a top plate; a base plate connectable to the housing to define an inner space between them; a lens module wound around by a coil; and at least one spring member holding and suspending the lens module in the inner space without causing the lens module to contact with the top plate and the base plate. With these arrangements, the spring member is not in a pre-tensioning state when the miniature lens auto-focusing structure is in a non-actuated state. Therefore, the miniature lens auto-focusing structure requires less actuating current and has smaller lens tilt angle than the conventional VCM auto-focusing structure, and can be manufactured at further reduced component cost.
