Abstract
A lens focusing structure includes a movable mechanism having at least one base, which has a camera lens centered therein and a winding externally wound therearound; an immovable mechanism having at least a frame with magnetic members mounted to four sides thereof, a front cover, and a rear cover, and the movable mechanism being centered in the frame; and at least one shock-absorbing element connected to and between the movable and the immovable mechanism for absorbing jitters produced by the movable mechanism when the latter is displaced to a focused point and then stopped, so as to suppress dynamic response time of the movable mechanism for going from a moving state back to a still state.

A method of suppressing dynamic response time of lens focusing structure, the lens focusing structure including a movable and an immovable mechanism, the method comprising the steps of:
- connecting at least one shock-absorbing element to and between the movable and the immovable mechanism;
- and
- using the at least one shock-absorbing element to absorb jitters produced by the movable mechanism when the latter is displaced to a focused point and then stopped, so as to suppress dynamic response time of the movable mechanism for going from a moving state back to a still state.
A lens focusing structure capable of suppressing dynamic response time thereof, comprising:
- a movable mechanism including at least one base, which has a camera lens centered therein and a winding externally wound therearound;
- an immovable mechanism including at least a frame with magnetic members mounted to four sides thereof, a front cover, and a rear cover;
- and the movable mechanism being centered in the frame;
- and
- at least one shock-absorbing element connected to and between the movable and the immovable mechanism for absorbing jitters produced by the movable mechanism when the latter is displaced to a focused point and then stopped, so as to suppress dynamic response time of the movable mechanism for going from a moving state back to a still state.
