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.
