Abstract:
1. A method for suppressing resonance in an anti-shake lens focusing module, compressing the following steps: providing a lens focusing structure having a first movable part and a first immovable part; and the first movable part holding a lens thereto for the lens to move along an optical axis forward and backward to achieve auto focusing; providing an anti-shake structure having a second movable part and a second immovable part; and the second movable part being movable to achieve image correction; providing at least one shock-absorbing material between the first movable part and the first immovable part as well as between the second movable part and the second immovable part; and using the shock-absorbing material to absorb any vibration caused by movements of the first movable part and the second movable part in achieving auto-focusing and image correction, respectively, so as to suppress any resonance possibly generated due to the movements of the first and the second moving parts.
