BACKGROUND OF THE INVENTION

Field of the Invention

The application relates in general to an optical mechanism, and in particular, to an optical mechanism having a driving module.

Description of the Related Art

As technology has advanced, a lot of electronic devices (such as digital cameras and smartphones) have been given the functionality of taking photographs and recording video. These electronic devices have become more commonplace, and have been developed to be more convenient and thin. More and more choices are provided for users to choose from.

Some electronic devices able to take photographs or record video include a lens driving module to drive an optical member to move, so as to facilitate auto-focus control and optical image stabilization (OIS). The light can pass through the lens and form an image on an image sensor.

However, the lens driving module usually comprises a plurality of magnets and a plurality of coils surrounding the optical member, so that the dimensions of the lens driving module and the electronic device cannot be reduced. Therefore, how to address the aforementioned problem has become an important issue.

BRIEF SUMMARY OF INVENTION

To address the deficiencies of conventional products, an embodiment of the invention provides an optical mechanism. The optical mechanism includes an optical member, a reflecting element, a holder, and a housing. The optical member includes a first optical lens and a second optical lens. Light propagates into the optical mechanist a first direction and is reflected by the reflecting element to propagate through the first and second optical lenses in a second direction. The holder supports the first and the second optical lenses, wherein the first and second optical lenses define an optical axis parallel to the second direction. The housing has a lower cover and a top cover, wherein the holder is accommodated in the housing. The first optical lens is closer to a light-entering end of the optical member than the second optical lens, and the first optical lens is larger than the second optical lens.
