Thefirst electrode 422 is electrically connected to the firstelectric conductor 62 and thesecond electrode 424 is electrically connected to the secondelectric conductor 64. Thefirst electrode 422 and thesecond electrode 424 are electrically connected to theconductive terminals 18 formed on the printedcircuit board 10 to electrically connect to a positive pole and a negative pole of the printedcircuit board 10. - The
filler 45 is at least one of a liquid filler and a solid filler. In at least one embodiment, thefiller 45 is a liquid filler. Thefiller 45 includes afirst liquid 452 and asecond liquid 454. Thefirst liquid 452 and thesecond liquid 454 cannot dissolve with each other. At least one of thefirst liquid 452 and thesecond liquid 454 is electrically conductive and deforms under voltage to change a shape and a curvature of a contacting surface between thefirst liquid 452 and thesecond liquid 454 thereby changing the focal distance of light passing through thefirst lens 41, and to make thelens module 100 has a zoom function. -
FIG. 4 shows an embodiment of anelectronic device 200. Theelectronic device 200 includes abody 202 and thelens module 100 mounted in thebody 202. Theelectronic device 200 may be a smart phone, a tablet computer, or the like. In at least one embodiment, theelectronic device 200 is a smart phone. - With the embodiments described above, the
lens module 100 includes afirst lens 41 capable of conducting electricity and producing deformation under voltage to change the focal distance of lights passing through thefirst lens 41, and is electrically connected to printedcircuit board 10 by at least twoelectric conductors 60, so thelens module 100 can change the focal distance by thefirst lens 41, not by a voice coil motor. Furthermore, defining at least two first receivinggrooves 50 in the outer wall of themicroscope base 44 and the outer wall of the bearingseat 20 which are used to receive theelectric conductors 60 can avoid increasing extra volume of thelens module 100, and can protect theelectric conductors 60 from damaging. - The embodiments shown and described above are only examples. Many details are often found in the art such as the other features of a lens module and an electronic device using the lens module. Therefore, many such details are neither shown nor described. Even though numerous characteristics and advantages of the present disclosure have been positioned forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes can be made in the detail, including in matters of shape, size, and arrangement of the parts within the principles of the present disclosure, up to and including the full extent established by the broad general meaning of the terms used in the claims. It will therefore be appreciated that the embodiments described above can be modified within the scope of the claims.
