At least a portion of the first magnet (1320) may be disposed at an area lower than the first sensor (1710). The entire first magnet (1320) may be disposed at a region lower than the first sensor (1710). A portion of the first magnet (1320) may be disposed below the first sensor (1710), and a remaining portion of the first magnet (1320) may be disposed at the same height as the first sensor (1710). That is, a portion of the first magnet (1320) may overlap the first sensor (1710) in a horizontal direction. The first magnet (1320) may be disposed at a region lower than the first sensing magnet (1730). The first magnet (1320) may be disposed at a region lower than the first compensation magnet (1740).

The first magnet (1320) may include first to fourth magnet units (1321, 1322, 1323, 1324) each spaced apart. The first magnet (1320) may include a first magnet unit (1321) disposed at the first lateral portion (1301) of the first housing (1310). The first magnet (1320) may include a second magnet unit (1322) disposed at the second lateral portion (1302) of the first housing (1310). The first magnet (1320) may include a third magnet unit (1323) disposed at a third lateral portion (1303) of the first housing (1310). The first magnet (1320) may include a fourth magnet unit (1324) disposed at a fourth lateral portion (1304) of the first housing (1310).

The first magnet (1320) may include a first magnet unit (1321) disposed on the first lateral portion (1301) of the first housing (1310), and a second magnet unit (1322) disposed on the second lateral portion (1302) of the first housing (1310). Each of the first magnet unit (1321) and the second magnet unit (1322) may include an inner surface facing the first coil (1220), an outer surface disposed opposite to the inner surface, and two lateral surfaces connecting the inner surface and the outer surface. At this time, a distance between both lateral surfaces of the first magnet unit (1321) may be shorter than a distance between both lateral surfaces of the second magnet unit (1322). That is, the lateral length of the inner surface of the first magnet unit (1321) may be shorter than the lateral length of the inner surface of the second magnet unit (1322). However, the longitudinal length of the inner surface of the first magnet unit (1321) may be the same as the longitudinal length of the inner surface of the second magnet unit (1322).

The distance between both lateral surfaces of the first magnet unit (1321) may be 50% of the distance between both lateral surfaces of the second magnet unit (1322). Alternatively, the distance between the two lateral surfaces of the first magnet unit (1321) may be 40% to 60% of the distance between the two lateral surfaces of the second magnet unit (1322). Alternatively, the distance between the two lateral surfaces of the first magnet unit (1321) may be 30% to 70% of the distance between the two lateral surfaces of the second magnet unit (1322).

The first magnet unit (1321) may be smaller in size than the second magnet unit (1322). The volume of the first magnet unit (1321) may be smaller than the volume of the second magnet unit (1322). The surface area of the first magnet unit (1321) may be smaller than the surface area of the second magnet unit (1322). As a result, it is possible to minimize magnetic field interference acting on the second lens driving apparatus (2000) by the first magnet (1320) by disposing the first magnet unit (1321) of a smaller size close to the second lens driving apparatus (2000).

The first magnet unit (1321) disposed on the first lateral portion (1301) of the first housing (1310) may be disposed more eccentrically toward the fourth lateral portion (1304) of the first housing (1310) than the third lateral portion (1303) of the first housing (1310). At this time, the first sensor (1710) facing the first sensing magnet (1730) may be disposed between the first lateral portion (1301) of the first housing (1310) and the third lateral portion (1303) of the first housing (1310). That is, the first magnet unit (1321) may be eccentrically disposed to be spaced apart from the first sensor (1710).

The first magnet unit (1321) may be disposed on the first lateral portion (1301) of the first housing (1310) by being inclined toward a corner portion of one side. The first magnet unit (1321) may be eccentrically disposed toward one side. The decentering direction of the first magnet unit (1321) may be opposite to the decentering direction of the fifth magnet unit (2321) of the facing second lens driving device (2000). The first magnet unit (1321) may be eccentrically disposed toward one side from the first lateral portion (1301) of the first housing (1310), and the fifth magnet unit (2321) may be eccentrically disposed toward the opposite direction of the eccentric direction of the first magnet unit (1321) from the fifth lateral portion (2301) of the second housing (2310), whereby the overlapping region between the first magnet unit (1321) and the fifth magnet unit (2321) may be minimized. In the structure, magnetic field interference between the first magnet unit (1321) and the fifth magnet unit (2321) can be minimized.

The first magnet unit (1321) may include a region that does not overlap with the fifth magnet unit (2321) of the second magnet (2320) of the second lens driving apparatus (2000) from the optical axis of the first lens driving apparatus (1000) toward the optical axis of the second lens driving apparatus (2000). At this time, the first magnet unit (1321) and the fifth magnet unit (2321) may be formed in a flat plate shape and disposed in parallel with each other. Further, the first magnet unit (1321) may not overlap with the fifth magnet unit (2321) of the second magnet (2320) of the second lens driving apparatus (2000) from the optical axis of the first lens driving apparatus (1000) toward the optical axis of the second lens driving apparatus (2000). As described above, with the structure, the magnetic field interference between the first magnet unit (1321) and the fifth magnet unit (2321) can be minimized.

The first magnet (1320) may include a third magnet unit (1323) disposed on the third lateral portion (1303) of the first housing (1310), and a fourth magnet unit (1324) disposed on the fourth lateral portion (1304) of the first housing (1310). Each of the third and fourth magnet units (1323, 1324) may include an inner surface facing the first coil (1220), an outer surface disposed opposite to the inner surfaces of the third and fourth magnet units (1323, 1324), and two lateral surfaces connecting the inner surfaces of the third and fourth magnet units (1323, 1324) and the outer surfaces of the third and fourth magnet units (1323, 1324). The distance between both lateral surfaces of the second magnet unit (1322) may be the same as the distance between both lateral surfaces of the third magnet unit (1323) and the distance between both lateral surfaces of the fourth magnet unit (1324).

The distance between the two lateral surfaces of the second magnet unit (1322), the distance between the two lateral surfaces of the third magnet unit (1323), and the distance between the two lateral surfaces of the fourth magnet unit (1324) may all be the same. At this time, the thickness and height of the second magnet unit (1322), the third magnet unit (1323), and the fourth magnet unit (1324) may all be the same. That is, the second magnet unit (1322), the third magnet unit (1323), and the fourth magnet unit (1324) may have the same shape and size. However, the first magnet unit (1321) may be formed to be smaller in size than the second magnet unit (1322), the third magnet unit (1323), and the fourth magnet unit (1324). In this case, due to the difference in magnetic force between the first to fourth magnet units (1321, 1322, 1323, 1324), the sensitivities to the X-axis direction and the Y-axis direction during the OIS driving may be different, which can be corrected by controlling the current values applied from the driver integrated circuit of the controller to the respective coil units of the second coil (1412 b). Alternatively, this may be corrected by differentiating the number of windings wound on each coil unit of the second coil (1412 b).

The length (horizontal length) of the long axis of the inner surface at the first magnet unit (1321) may be shorter than the length of the long axis of the inner surface of the second to fourth magnet units (1322, 1323, 1324). The length (vertical length) of the minor axis of the inner surface of the first magnet unit (1321) may be the same as the length of the minor axis of the inner surfaces of the second to fourth magnet units (1322, 1323, 1324). The thickness of the first magnet unit (1321) may be the same as the thickness of the second to fourth magnet units (1322, 1323, 1324).

The first lens driving apparatus (1000) may include a dummy member (1330). The first lateral portion (1301) of the first housing (1310) may be formed with a dummy member (1330) having weaker magnetism than the first magnet unit (1321), or may be formed with a dummy member (1330) having no magnetism. The magnetic properties of the dummy member (1330) may be weak or may not be magnetic. In the present exemplary embodiment, an unbalance of weight may be generated because the first magnet unit (1321) is smaller in size and weight than the other magnet units, which may be a factor causing the inclination of the first housing (1310). As a result, a dummy member (1330) correcting the weight unbalance may be provided, thereby solving the weight unbalance.

The dummy member (1330) may be configured to adjust a center of gravity of the first magnet (1320). More specifically, the dummy member (1330) may be provided so as to solve unbalance generated when the weight of the first magnet unit (1321) is different from the weights of the other magnet units. The sum of the mass of the dummy member (1330) and the mass of the first magnet unit (1321) may be the same as the mass of the second magnet unit (1322). Centers of the dummy member (1330), the first magnet unit (1321), and the second magnet unit (1322) may be disposed on a central axis of the first housing (1310). Further, the dummy member (1330) and the centers of gravity of the first to fourth magnet units (1321, 1322, 1323, 1324) may be disposed on the central axis of the first housing (1310). With the structure, it is possible to prevent inclination from the first housing (1310) due to the unbalance of the weight of the first magnet (1320).

The dummy member (1330) may be disposed at one side of the first magnet unit (1321). The dummy member (1330) may be disposed adjacent to the first magnet unit (1321). The dummy member (1330) may be disposed to contact the first magnet unit (1321). The dummy member (1330) may be disposed to extend from the first magnet unit (1321) to the longitudinal direction. A sum of a distance between two lateral surfaces of the dummy member (1330) and a distance between two lateral surfaces of the first magnet unit (1321) may be the same as a distance between two lateral surfaces of the second magnet unit (1322). That is, the dummy member (1330) may be formed to have a size corresponding to a region where the first magnet unit (1321) is omitted, compared to the second magnet unit (1322). The dummy member (1330) may have the same height as that of the first magnet unit (1321). The dummy member (1330) may have the same thickness as that of the first magnet unit (1321). The dummy member (1330) may have the same width as that of the first magnet unit (1321). At this time, the height of the dummy member (1330) may be a length of the inner surface of the dummy member (1330) in a longitudinal direction (short side direction, vertical direction), and the width of the dummy member (1330) may be a length of the inner surface of the dummy member (1330) in a lateral direction (long side direction, horizontal direction). The thickness of the dummy member (1330) may be a distance between an inner surface and an outer surface of the dummy member (1330). In a modification, any one or more of the height, thickness and width of the dummy member (1330) may be different from those of the first magnet unit (1321).

The dummy member (1330) may be disposed on the first lateral portion (1301) of the first housing (1310) to be inclined toward a corner portion { a corner portion disposed at an opposite side of a corner portion disposed adjacent to the first magnet (1321) } of the other side. The dummy member (1330) may be eccentrically disposed at the other side. The eccentric direction of the dummy member (1330) may be opposite to the eccentric direction of the first magnet unit (1321). Accordingly, the eccentric direction of the dummy member (1330) may match the eccentric direction of the fifth magnet unit (2321), and thus, the overlapping region between the dummy member (1330) and the fifth magnet unit (2321) may be maximized. The structure may minimize magnetic field interference between the first magnet unit (1321) and the fifth magnet unit (2321).

The first lens driving apparatus (1000) may include a first stator (1400). The first stator (1400) may be disposed under the first housing (1310). The first stator (1400) may be disposed below the first OIS mover (1300). The first stator (1400) may face the first OIS mover (1300). The first stator (1400) may movably support the first OIS mover (1300). The first stator (1400) may move the first OIS mover (1300). At this time, the first AF mover (1200) may also move together with the first OIS mover (1300).

The first stator (1400) may include a first circuit member (1410). The first circuit member (1410) may be coupled with the first support member (1600).

At this time, the distance between both lateral surfaces of the fifth magnet unit (2321) may be shorter than the distance between both lateral surfaces of the sixth magnet unit (2322). That is, the lateral length of the inner surface of the fifth magnet unit (2321) may be shorter than the lateral length of the inner surface of the sixth magnet unit (2322). However, the longitudinal length of the inner surface of the fifth magnet unit (2321) may be the same as the longitudinal length of the inner surface of the sixth magnet unit (2322).

The distance between both lateral surfaces of the fifth magnet unit (2321) may be 50% of the distance between both lateral surfaces of the sixth magnet unit (2322).

The fifth magnet unit (2321) may be eccentrically disposed toward one side from the fifth lateral part (2301) of the second housing (2310), and the first magnet unit (1321) may be eccentrically disposed toward the opposite direction of the eccentric direction of the fifth magnet unit (2321) from the first lateral part (1301) of the first housing (1310), whereby the overlapping region between the fifth magnet unit (2321) and the first magnet unit (1321) may be minimized. In the structure, magnetic field interference between the fifth magnet unit (2321) and the first magnet unit (1321) may be minimized.

The fifth magnet unit (2321) may include a region that does not overlap with the first magnet unit (1320) of the first lens driving apparatus (1000) from the optical axis of the second lens driving apparatus (2000) toward the optical axis of the first lens driving apparatus (1000). Further, the fifth magnet unit (2321) may not overlap with the first magnet unit (1321) of the first magnet (1320) of the first lens driving apparatus (1000) from the optical axis of the second lens driving apparatus (2000) toward the optical axis of the first lens driving apparatus (1000). As described above, with the structure, the magnetic field interference between the fifth magnet unit (2321) and the first magnet unit (1321) can be minimized.

The second magnet (2320) may include a seventh magnet unit (2323) disposed on the seventh lateral portion (2303) of the second housing (2310), and an eighth magnet unit (2324) disposed on the eighth lateral portion (2304) of the second housing (2310). Each of the seventh magnet unit (2323) and the eighth magnet unit (2324) may include an inner surface facing the third coil (2220), an outer surface disposed opposite the inner surfaces of the seventh magnet unit (2323) and the eighth magnet unit (2324), and two lateral surfaces connecting the inner surfaces of the seventh magnet unit (2323) and the eighth magnet unit (2324) and the outer surfaces of the seventh magnet unit (2323) and the eighth magnet unit (2324). A distance between both lateral surfaces of the sixth magnet unit (2322) may be the same as a distance between both lateral surfaces of the seventh magnet unit (2323) and a distance between both lateral surfaces of the eighth magnet unit (2324).

The distance between both lateral surfaces of the sixth magnet unit (2322), the distance between both lateral surfaces of the seventh magnet unit (2323), and the distance between both lateral surfaces of the eighth magnet unit (2324) may all be the same. At this time, the thickness and height of the sixth magnet unit (2322), the seventh magnet unit (2323) and the eighth magnet unit (2324) may all be the same. That is, the sixth magnet unit (2322), the seventh magnet unit (2323), and the eighth magnet unit (2324) may have the same shape and size. However, the fifth magnet unit (2321) may be formed to be smaller in size than the sixth magnet unit (2322), the seventh magnet unit (2323) and the eighth magnet unit (2324). In this case, due to the difference in magnetic force between the fifth to eighth magnet units (2321, 2322, 2323, 2324), the sensitivities in the X-axis direction and the Y-axis direction during the OIS driving may be different, which may be corrected by controlling the values of the currents applied from the driver integrated circuit of the controller to the respective coil units of the fourth coil (2412 b). Alternatively, this may be corrected by differentiating the number of windings wound on each coil unit of the fourth coil (2412 b).

The length (horizontal length) of the long axis of the inner surface of the fifth magnet unit (2321) may be shorter than the length of the long axis of the inner surfaces of the sixth to eighth magnet units (2322, 2323, 2324). The length (horizontal length) of the minor axis of the inner surface of the fifth magnet unit (2321) may be the same as the length of the minor axis of the inner surfaces of the sixth to eighth magnet units (2322, 2323, 2324). The thickness of the fifth magnet unit (2321) may be the same as the thicknesses of the sixth to eighth magnet units (2322, 2323, 2324).

The second lens driving apparatus (2000) may include a dummy member (2330). The fifth lateral portion (2301) of the second housing (2310) may be formed with a dummy member (2330) having a magnetic property weaker than that of the fifth magnet unit (2321), or may be formed with a dummy member (2330) having no magnetic property. The magnetic properties of the dummy member (2330) may be weak or may be non-magnetic. In the present exemplary embodiment, since the fifth magnet unit (2321) is small in size and weight compared to the other magnet units, an imbalance in weight may be generated, which may be a factor causing the inclination of the second housing (2310). As a result, a dummy member (2330) correcting the weight unbalance may be provided, thereby solving the weight unbalance.

The dummy member (2330) may be configured to adjust a center of gravity of the second magnet (2320). More specifically, the dummy member 2330 is provided to solve the unbalance generated when the weight of the fifth magnet unit (2321) is different from the weights of the other magnet units. The sum of the mass of the dummy member (2330) and the mass of the fifth magnet unit (2321) may be the same as the mass of the sixth magnet unit (2322). Centers of the dummy member (2330), the fifth magnet unit (2321) and the sixth magnet unit (2322) may be disposed on a central axis of the second housing (2310). Further, the centers of gravity of the dummy member (2330) and the fifth to eighth magnet units (2321, 2322, 2323, 2324) may be disposed on the central axis of the second housing (2310). With the structure, it is possible to prevent inclination from the second housing (2310) due to the weight unbalance of the second magnet (2320).

The dummy member (2330) may be disposed at one side of the fifth magnet unit (2321). The dummy member (2330) may be disposed adjacent to the fifth magnet unit (2321). The dummy member (2330) may be disposed to contact the fifth magnet unit (2321). The dummy member (2330) may be disposed to extend from the fifth magnet unit (2321) to the longitudinal direction. A sum of a distance between both lateral surfaces of the dummy member (2330) and a distance between both lateral surfaces of the fifth magnet unit (2321) may be the same as a distance between both lateral surfaces of the sixth magnet unit (2322). That is, the dummy member (2330) may be formed to have a size corresponding to a region where the fifth magnet unit (2321) is omitted, as compared to the sixth magnet unit (2322). The dummy member (2330) may have the same height as that of the fifth magnet unit (2321). The dummy member (2330) may have the same thickness as that of the fifth magnet unit (2321). The dummy member (2330) may have the same width as that of the fifth magnet unit (2321). At this time, the height of the dummy member (2330) may be a length of the inner surface of the dummy member (2330) in a longitudinal direction (short side direction, vertical direction), and the width of the dummy member (2330) may be a length of the inner surface of the dummy member (2330) in a lateral direction (long side direction, horizontal direction). The thickness of the dummy member (2330) may be the distance between the inner and outer surfaces of the dummy member (2330). In a modification, any one or more of the height, thickness and width of the dummy member (2330) may be different from the height, thickness and width of the fifth magnet unit (2321).

The dummy member (2330) may be disposed on the fifth lateral portion (2301) of the second housing (2310) to be inclined toward the corner portion { the corner portion on the opposite side of the corner portion disposed adjacent to the fifth magnet (2321) } on the other side. The dummy member (2330) may be eccentrically disposed at the other side. The eccentric direction of the dummy member (2330) may be opposite to that of the fifth magnet unit (2321). Accordingly, the eccentric direction of the dummy member (2330) may match the eccentric direction of the first magnet unit (1321), and thus, the overlapping region between the dummy member (2330) and the first magnet unit (1321) may be maximized. The structure may minimize magnetic field interference between the fifth magnet unit (2321) and the first magnet unit (1321).

An object of the present exemplary embodiment is to improve characteristics of a camera module by maintaining a minimum gap between products through an electromechanical optimization (magnetic field interference avoidance) design in order to solve a phenomenon that electromagnetic field interference is generated between products to affect other products when a dual OIS camera is applied. At this time, the aforementioned feature of the camera module may be a zoom feature of the camera module or the like. More specifically, in order to utilize a zoom function or the like, the distance between products must be close. In particular, a gap distance of 1mm is required. However, in order to make the distance between the products closer, a problem arises in that the electromagnetic force involved in the magnetic field interference is reduced.

In an exemplary embodiment, the electromagnetic force is maximized while the electromagnetic force of the X, Y axis is equalized, thereby eliminating tilt and minimizing electromagnetic field interference between products. In an exemplary embodiment, when CLAF (closed loop auto focus) is added, the sensing magnet and the compensation magnet may be arranged in symmetrical directions. Further, the OIS hall integrated circuit may overlap over a portion of the magnet or the entire magnet. Alternatively, the OIS hall integrated circuit may overlap over a portion of the magnet or the entire magnet during driving. The OIS hall integrated circuit may be disposed at the same position as the first lens driving device and the second lens driving device, or may be disposed in a diagonal direction. In an exemplary embodiment, the first lens driving device and the second lens driving device may be implemented separately. In an exemplary embodiment, the configuration may be arranged to minimize the phenomenon that the hall ic affects the electromagnetic field of other products by providing the position elements as shown in fig. 17 to 20. In an exemplary embodiment, the position detection element, such as a hall integrated circuit, may include a hall integrated driver. The positions of the hall ic and the sensing magnet may be changed with respect to each other. The hall ic may be provided on the bobbin or on the housing. The hall ics may be provided in one or more components to determine or correct the tilt value. The hall ic may also be used for temperature sensing functions.

By way of exemplary embodiments, the present invention relates to a VCM (voice coil motor), camera module and mobile phone configured to reduce the size of a portion of a driving magnet in both OIS and OIS dual cameras and maintain a minimum distance between the two. By way of example embodiments, the present invention relates to a structure in which sensing magnets are arranged diagonally and driving magnets between products are kept at a maximum distance. By way of example embodiments, the present invention relates to a camera module in which the actuator structures (magnet arrangement relationship, positional element setting relationship, coil arrangement relationship) of two cameras are the same. The OIS hall integrated circuit may be configured to overlap a portion or all of the magnet. The included OIS hall integrated circuit, when driven, may be configured to overlap a portion or all of the magnet. In the case of CLAF, the AF hall integrated circuit may be disposed diagonally, and the OIS hall integrated circuit may be disposed on a straight line portion.
