Patent ID: 7417811

Claim:
A lens module, comprising: at least one lens having a principal optical axis; a lens barrel receiving the at least one lens therein, the lens barrel having a plurality of anchoring posts on an outer wall thereof; and at least one lens barrel driving assembly comprising: a magnetic block having a plurality of anchoring holes engagingly receiving the anchoring posts of the lens barrel therein, with the lens barrel being fixedly attached to the magnetic block, the magnetic block being oriented in a manner such that a magnetization direction thereof is substantially parallel to the principal optical axis of the at least one lens; two elastic members each having a first end and an opposite second end, the first ends thereof being attached to opposite ends of the magnetic block; a frame receiving the elastic members and the magnetic block therein, the second ends of the elastic members being secured to the frame in a manner such that the magnetic block is suspended and movable in the frame in the magnetization direction thereof; and first and second magnetic generators arranged adjacent to the frame and at opposite sides of the magnetic block, the first and second magnetic generators being configured for generating a magnetic field for driving the magnetic block jointly with the lens barrel to move in a direction along the principal optical axis of the at least one lens.
