Abstract: A method and a structure for suppressing resonance in an anti-shake lens focusing module are disclosed. The resonance suppressing method includes the steps of providing a lens focusing structure having a first movable part and a first immovable part; providing an anti-shake structure having a second movable part and a second immovable part; providing at least one shock-absorbing material between the first movable and immovable parts as well as between the second movable and immovable parts; and using the shock-absorbing material to absorb any vibration caused by movements of the first and the second movable part, so as to suppress any resonance possibly generated due to the movements of the first and the second movable part.

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.
