Embodiment 1

[0015] Please refer to FIG. 1 , which shows a perspective view of a lens module according to Embodiment 1 of the present invention. The lens module 100 includes a housing 30 , a lens 60 , an elastic body, a voice coil motor 40 and a magnetic component 80 . In this embodiment, the lens 60 is taken as an example for illustration. However, it can also be composed of several lenses, and the number of lenses is not intended to limit the technical scope of the present invention. And the elastic system is described by taking the first elastic sheet 10 as an example. The casing 30 has an accommodating space 31, and the accommodating space 31 has an opening 31a. The voice coil motor 40 includes a coil moving part 42 and a magnet fixing part 41 . The coil moving part 42 is movably coupled to the casing 30 via the first elastic sheet 10 , and is disposed in the accommodating space 31 for clamping the lens 60 . The magnet fixing part 41 surrounds the coil moving part 42 in a manner of...

Embodiment 2

[0021] Please refer to FIG. 5 , which shows a block diagram of the electronic device of the second embodiment. The electronic device 500 includes a lens module 100 , a sensing component 300 and a storage unit 400 . The lens module 100 of this embodiment adopts the lens module 100 of Embodiment 1, and the same components use the same reference numerals, which will not be repeated here. The lens module 100 can be applied in various electronic devices 500 , such as mobile communication devices, notebook computers, cameras or video recorders, and the like. The lens module 100 is disposed between the object and the sensing component 300 . After passing through the lens module 100 , the light from the object is focused on the sensing component 300 to form an image. The storage unit 400 is electrically connected to the sensing element 300 for storing images.

[0022] The lens module disclosed in the above embodiments of the present invention and the electronic device using the mod...
