[0040] see figure 1 , The magnet fixing frame 10 provided by the first embodiment of the present invention is used to fix the magnet in the voice coil motor, which is roughly a square frame. It can be understood that the magnet holder 10 can also be in other shapes, such as a circle or other polygons.
[0041] The magnet holder 10 includes a first side wall 11 , a second side wall 12 , a third side wall 13 , a fourth side wall 14 and four resisting elastic pieces 16 . The first side wall 11 , the second side wall 12 , the third side wall 13 , and the fourth side wall 14 connect end to end to form a receiving space 10 a. Wherein, the first side wall 11 is opposite to the third side wall 13 , and the second side wall 12 is opposite to the fourth side wall 14 .
[0042] The first sidewall 11 defines a first stepped hole 110 . The second sidewall 12 defines a second stepped hole 120 . The third sidewall 13 defines a third stepped hole 130 . The fourth sidewall 14 defines a fo...
