       FIG.  1    is an exploded view of a lens component of a camera assembly of the present disclosure.  FIG.  2    is a cross-sectional view along line A-A′ in  FIG.  1   .  FIG.  3    and  FIG.  4    are exploded views of the camera assembly of the present disclosure. As shown in the figures, the present disclosure provides a camera assembly  1 , which comprises a casing  11 , a carrying component  12 , a magnetic component  13 , a light sensing component  14 , and a carrying board  15 . The casing  11  comprises a lens accommodating groove  110 , an housing  111 , and a base  112  on which the housing  111  is disposed. The lens accommodating groove  110  is disposed between the housing  111  and the base  112 . An opening of the lens accommodating groove  110  is disposed at the housing  111 . The carrying component  12  comprises a carrying body  121  and a first coil  122  disposed at the periphery of the carrying body  121 . The carrying component is assembled in the lens accommodating groove  110 . The magnetic component  13  is disposed at the periphery of the first coil  122 . The magnetic component  13  is disposed on an inner wall of the lens accommodating groove  110 . The light sensing component  14  comprises a light sensing member  141 , a baseplate  142 , and a second coil  143 . The light sensing member  141  is disposed on the baseplate  142 . The light sensing member  141  is correspondingly disposed at the bottom of the lens accommodating groove. The second coil  143  is disposed at the periphery of the light sensing member  141  and is disposed below the magnetic component  13 . The carrying board  15  carries the bottom of the light sensing component  14  and is slidably disposed on the base  112 . The camera assembly  1  further comprises a lens component  16 , which is assembled to the carrying body  121  and is disposed in the lens accommodating groove  110 . 
     The base comprises a plurality of recesses  1121  and a plurality of balls  1122  slidably disposed in the plurality of recesses  1121 . A bottom surface of the carrying board  15  is in contact with the plurality of balls  1122 . Wherein, the bottom surface of the carrying board  15  further comprises a plurality of bumps  151  extended into the plurality of recesses  1121 . The thickness of each of the bumps  151  is smaller than the depth of each of the recesses  1121 . The outer diameter of each of the bumps  151  is smaller than the diameter of the opening of each of the recesses  1121 . The plurality of balls  1122  are respectively disposed between the corresponding recess  1121  and the bump  151 . In this way, when the bump  151  is disposed in the recess  1121 , it can be displaced and rotated in the recess  1121 . Meanwhile, the displacement range and rotation range of the bump  151  are also limited by the opening of the recess  1121 . 
     Besides, the camera assembly  1  further comprises a plurality of first magnetic members  171  and a plurality of second magnetic members  172 . The plurality of first magnetic members are disposed on the base  112 . The plurality of second magnetic members  172  are disposed at positions on the carrying board  15  corresponding to the positions on the base  112  where the plurality of first magnetic members  171  are disposed. The plurality of first magnetic members  171  and the plurality of second magnetic members  172  are mutually attracted. In this way, when the plurality of humps  151  of the carrying board  15  slide over the balls  1122  of the base  112 , the bumps  151  of the carrying board  15  could move in close contact with the plurality of balls  1122  without having the carrying board  15  to detach from the base  112 . In some embodiments, the first magnetic member  171  is a magnetic conductive sheet, and the second magnetic member  172  is a magnet. A magnet and a magnetic conductive sheet could be selected for the first magnetic member  171  and the second magnetic member  172  according to actual requirements. 
       FIG.  5    is a perspective view of a driving mechanism of a camera assembly of the first embodiment of the present disclosure.  FIG.  6    and  FIG.  7    are schematic diagrams of driving directions of the driving mechanism of the present disclosure. As shown in the figures, in this embodiment, the first coil  122  is disposed around the periphery of the carrying body  121 . When an electric current is introduced into the first coil  122 , the first coil  122  would generate a magnetic force against the magnetic component  13  to drive the carrying body  121  to displace. 
     Furthermore, in this embodiment, the number of the second coils  143  is multiple. The plurality of second coils  143  are disposed at the periphery of the light sensing member  141 . When introducing an electric current into the plurality of second coils  143 , the plurality of second coils  143  would generate a magnetic force against the magnetic component  13  to drive the light sensing component  14  to horizontally displace or rotate. Besides, the carrying board  15  carries the bottom of the light sensing component  14 . The bottom surface of the carrying board  15  is in contact with the plurality of balls  1122 . Since the bottom surface of the carrying board  15  and a surface of the base  112  are not affected by friction, the carrying board  15  would not affect the horizontal displacement or rotation of the light sensing component  14 . 
     Referring to  FIG.  7    again, in this embodiment, the light sensing component  14  further comprises a coil plate member  144 . The plurality of second coils  143  could be firstly disposed on or embedded in the coil plate member  144 , which is annular, then the coil plate member  144  could dispose the plurality of second coils  143  at the periphery of the light sensing member  141  and could secure the plurality of second coils  143  at the outer side of the light sensing member  141 . In this way, the plurality of second coils  143  could be disposed at the outer side of the light sensing member  141 , which facilitates the assembly process of the camera assembly  1 . 
     Moreover, the plurality of second coils  143  comprise a first direction coil group  1431  and a second direction coil group  1432 . The first direction coil group  1431  is disposed on two opposite sides of the light sensing member  141 . The second direction coil group  1432  is disposed on the other two opposite sides of the light sensing member  141 . The magnetic component  13  comprises a first direction magnet group  131  and a second direction magnet group  132 . The first direction magnet group  131  is disposed above the first direction coil group  1431 , and the second direction magnet group  132  is disposed above the second direction coil group  1432 . Wherein, the first direction coil group  1431  further comprises a plurality of first side coils  14311  and a plurality of second side coils  14312 . The plurality of first side coils  14311  are disposed at a side of the light sensing member  141 , and the plurality of second side coils  14312  are disposed at another side of the light sensing member  141  opposite to the side where the plurality of first side coils  14311  are disposed. Besides, the first direction magnet group  131  comprises a plurality of first side magnets  1311  and a plurality of second side magnets  1312 . The plurality of first side magnets  1311  are respectively disposed above the plurality of first side coils  14311 , and the plurality of second side magnets  1312  are respectively disposed above the plurality of second side coils  14312 . 
     Referring to  FIG.  6    again, directions of the X. Y, and Z axes are marked fir the description of the driving direction of the driving mechanism. When an electric current is introduced into the first coil  122  to generate a corresponding magnetic field, the magnetic field generated by the first coil  122  would generate an attractive or a repulsive force to the permanent magnetic field of the magnetic component  13 . This implies that the first coil  122  could control the strength of the attractive and repulsive forces by introducing electric currents in various intensities. The carrying body  121  is driven by the first coil  122  to move back and forth in a vertical direction (i.e., the displacement in Z-axis direction), and the lens component  16  is assembled to the carrying body  121  so that the carrying body  121  can move closer to or away f om the light sensing component  14 , thereby adjusting the distance between the lens component  16  and the light sensing member  141  for executing the focusing for the image. 
     Referring to  FIG.  7    again, in this embodiment, directions of the X, Y, and Z axes are marked for the description of the driving direction of the driving mechanism. When an electric current is introduced into the second coil  143  to generate a corresponding magnetic field, the magnetic field generated by the second coil  143  would generate an attractive or a repulsive force to the permanent magnetic field of the magnetic component  13 . This implies that the second coil  143  could control the strength of the attractive and repulsive forces by introducing electric currents in various intensities. The light sensing component  14  is driven by the second coil  143  to be displaced or rotated horizontally. Wherein, the first direction coil group  1431  of the second coil  143  could generate an attractive or repulsive force in the first direction (i.e., the X-axis direction) relative to the first direction magnet group  131  of the magnetic component  13 , and the first direction coil group  1431  could drive the light sensing component  14  to move back and forth in the first direction (i.e., the X-axis direction). Besides, the second direction coil group  1432  of the second coil  143  could generate an attractive or repulsive force in the second direction (i.e., the Y-axis direction) relative to the second direction magnet group  132  of the magnetic component  13 , and the second direction coil group  1432  could drive the light sensing component  14  to move back and forth in the second direction (i.e., the Y-axis direction). The displacement of the lens component  16  of this embodiment can be adjusted along the vertical direction, the first direction, and the second direction which are the three axial directions of X, Y, and Z. 
     Furthermore, the first direction coil group  1431  further comprises a plurality of first side coils  14311  and a plurality of second side coils  14312 . The number of first side coils  14311  is two, and the number of first side magnets  1311  is two. The plurality of first side coils  14311  are arranged side by side along a side of the light sensing component  14 , and the plurality of first side coils  14311  simultaneously correspond to the plurality of first side magnets  1311  of the first direction magnet group  131 . The number of second side coils  14312  is two, and the number of second side magnets  1312  is two. The plurality of second side coils  14312  are arranged side by side along another side of the light sensing component  14 , and the plurality of second side coils  14312  simultaneously correspond to the plurality of second side magnets  1312  of the first direction magnet group  131 . In this embodiment, the plurality of first side coils  14311  and the plurality of second side coils  14312  could generate an attractive or a repulsive force in the first direction (i.e., the X-axis direction) relative to the magnetic component  13  by introducing electric current to the plurality of first side coils  14311  and the plurality of second side coils  14312  in the same direction. 
     In this embodiment, one of the two first side coils  14311  is referenced as  14311 A while the other is  14311 B, one of the two second side coils  14312  is referenced as  14312 A while the other is  14312 B, one of the two first side magnets  1311  is referenced as  1311 A while the other is  1311 B, and one of the two second side magnets  1312  is referenced as  1312 A while the other is  1312 B. Wherein, the first side coil  14311 A is opposed to the second side coil  14312 A, and the first side coil  14311 B is opposed to the second side coil  14312 B. An electric current is introduced into the first side coil  14311 A and the second side coil  14312 A in the same direction so that the first side coil  14311 A could be positively displaced in the first direction X relative to the first side magnet  1311 A, The second side coil  14312 A could be positively displaced in the first direction X relative to the second side magnet  1312 A, that is, displaced in a direction from the second side coil  14312 A toward the first side coil  14311 A. 
     Besides, the first side coil  14311 B and the second side coil  14312 B are also introduced with an electric current in the same direction, so the first side coil  14311 B is negatively displaced in the first direction X relative to the first side magnet  1311 B, and the second side coil  14312 B is negatively displaced in the first direction X relative to the second side magnet  1312 B, that is, displacement in a direction from the first side coil  14311 B to the second side coil  14312 B. In this way, the light sensing component  14  close to one side of the first side coil  14311 A, and one side of the second side coil  14312 A would be driven to be displaced in a direction from the second side coil  14312 A toward the first side coil  14311 A, and the light sensing component  14  close to one side of the first side coil  14311 B and one side of the second side coil  14312 B would be driven to be displaced in the direction from the first side coil  14311 B toward the second side coil  14312 B, thereby the light sensing component  14  can be driven to move in a clockwise direction. On the contrary, an electric current in reverse direction can also be introduced for counterclockwise displacement for the light sensing component  14 . 
       FIG.  8    is a perspective view of a driving mechanism of a camera assembly of the second embodiment of the present disclosure. As shown in the figure, the difference between the driving mechanism of this embodiment and the first embodiment lies in the magnetic component  13 . In this embodiment, the magnetic components  13  are four permanent magnets and are disposed at the periphery of the first coil  122 . Meanwhile, the magnetic component  13  is disposed above the second coil  143 . The magnetic components  13  are not limited to four permanent magnets in this embodiment, it can be configured according to the number of coils. Back to  FIG.  7   , the four permanent magnets correspond to the plurality of first side coils  14311  and the plurality of second side coils  14312 , respectively. The two permanent magnets correspond to the second direction coil group  1432 . 
       FIG.  9    is a perspective view of a driving mechanism of a camera assembly of the third embodiment of the present disclosure. As shown in the figure, the difference between the driving mechanism of this embodiment and the first embodiment lies in the second direction coil group  1432 . The second direction coil group  1432  further comprises a plurality of first side coils  14321  and a plurality of second side coils  14322 . The number of coils in the second direction coil group  1432  is the same as the number of coils in the first direction coil group  1431 . In this way, the horizontal displacement or horizontal rotation of the light sensing component  14  could be precisely adjusted through the electric current directions of the first direction coil group  1431  and the second direction coil group  1432  for an accurate light compensation for the light sensing member  141 . 
     In this embodiment, the number of magnetic components  13  or the number of coils of the first direction coil group  1431  and of the second direction coil group  1432  could be adjusted according to requirements to adjust the light sensing member  141  for light compensation. 
       FIG.  10    is a structural diagram of a flexible circuit board of the camera assembly of the first embodiment of the present disclosure.  FIG.  11    and  FIG.  12    are perspective views of the flexible circuit board of the camera assembly of the first embodiment of the present disclosure.

The flexible circuit board  18  of this embodiment is disposed at the periphery of the light sensing component  14 , which allows the moving range of the light sensing component  14  less restricted by the circuit of the flexible circuit board  18 . When the light sensing component  14  is horizontally displaced or rotated, the flexible circuit board  18  could provide a proper space for displacement for the light sensing component  14  since the flexible circuit board  18  is disposed at the periphery of the light sensing component  14 . 
     In this embodiment, the number of flexible circuit boards  18  is two. The first end parts  181  of the two flexible circuit boards  18  are connected to two opposite sides of the baseplate  142  and are extending below the carrying board  15  to two sides of the carrying board  15 .

As shown in the figures, the difference between this embodiment and the first embodiment of the flexible circuit board lies in the arrangement of the flexible circuit board  18 . Similarly, the number of flexible circuit boards  18  is two. The first end parts  181  of the two flexible circuit boards  18  are connected to the same side of the baseplate  142  and are extending below the carrying board  15  to the same side of the carrying board  15 . The body parts  183  of the two flexible circuit boards  18  are winding upward from the same side of the carrying board  15 , and when the body parts  183  of the two flexible circuit boards  18  extend vertically upward relative to a surface of the baseplate  142 , the body parts  183  of the two flexible circuit boards  18  are arranged in opposite directions and extend along the periphery of the light sensing component  14  and are connected to the second end parts  182 . 
     Referring to  FIG.  3    and  FIG.  4    again, in some embodiments, the first end parts  181  of the two flexible circuit boards  18  are parallel to the surface of the baseplate  142 . The body part  183  is vertical to the surface of the baseplate  142 , and the second end part  182  is vertical to the surface of the baseplate  142 . In some embodiments, the body parts  183  of the two flexible circuit boards  18  are disposed on the X-Y plane between the housing  111  and the light sensing component  14 , and the second end parts  182  of the two flexible circuit boards  18  are exposed from the housing  111 . In some embodiments, the housing  111  comprises two notches  1110  from which the second end parts  182  of the two flexible circuit boards  18  are exposed. In some embodiments, the base  112  comprises two securing sidewalls  1123 , which extend vertically upward from sides of the base  112  and correspond to the two notches  1110 . The second end parts  182  of the two flexible circuit boards  18  are disposed on the two securing sidewalk  1123  and are exposed from the two notches  1110 , 
       FIG.  16    and  FIG.  17    are exploded views of internal components of the camera assembly of the present disclosure. As shown in the figures, in this embodiment, the casing  11  further comprises a holder  113  disposed inside the housing  111  and comprises a plurality of recesses  1131 . The magnetic component  13  is disposed in the plurality of recesses  1131  of the holder  113 , which surrounds the carrying component  12 . The camera assembly  1  further comprises a first spring member  191  and a second spring member  192 . An upper surface of the holder  113  comprises an accommodating recess  1132 , and four sides of a lower surface of the holder comprise a securing column. The first spring member  191  is disposed in the accommodating recess  1132  of the holder  113 , and the first spring member  191  is disposed between the holder  113  and the housing  111 . The second spring member  192  is disposed at the securing column  1133  of the holder  113 , and the second spring member  192  is disposed at the periphery of the light sensing member  141 . Wherein, an inner side of the first spring member  191  abuts against the top of the lens component  16 , and an inner side of the second spring member  192  supports the periphery of the bottom of the lens component  16 . When the lens component  16  is driven by the carrying body  121 , the first spring member  191  and the second spring member  192  could keep the balance during the movement of the lens component  16 . Meanwhile, the first spring member  191  and the second spring member  192  could be used as circuits for providing electric power or signal transmission. Besides, the flexible circuit board  18  disposed around the light sensing component  14  is disposed in the gap between the housing  111  and the holder  113  to limit the circuit path of the flexible circuit board  18 . 
     In summary, embodiments of the present disclosure provide a camera assembly having a driving mechanism for focusing with a driving mechanism for optical image stabilization to allow the first coil of the carrying component and the second coil of the light sensing component to jointly correspond to the magnetic field of the magnetic component, Thus, the space occupied in the housing can be reduced, and the cost can also be reduced.
