Description

Technical Field

[0001] This embodiment relates to a camera module.

Background Art

[0002] With the widespread popularization of various mobile terminals and the normalization of wireless Internet services, consumers' requirements related to mobile terminals have become diversified, and various types of additional devices are attached to mobile terminals.

[0003] Among them, a typical one is a camera module that captures a subject in a photo or video. On the other hand, in recent years, a dual camera module in which two camera modules are arranged side by side has been studied. By the way, in the conventional dual camera module, there is a problem that the distance between the camera modules is narrow and mutual magnetic field interference occurs.

[0004] In addition, an autofocus function that automatically adjusts the focus according to the distance of the subject is applied to the camera module. However, in recent years, the size and weight of the lens have increased, the stroke range of lens movement has also increased, and the electromagnetic force for autofocus drive at the time of design has become insufficient, and a phenomenon in which the drive linearity collapses has appeared.

The second coil 1430 can interact electromagnetically with the first magnet 1320. In this case, when a current is supplied to the second coil 1430 and a magnetic field is formed around the second coil 1430, the first magnet 1320 can move with respect to the second coil 1430 due to the electromagnetic interaction between the second coil 1430 and the first magnet 1320.

The length of the wire of the second elastic member 1600 can be ensured via the first terminal 1450. More specifically, due to the reduction of the overall height of the first camera module, even if the distance between the first upper elastic member 1510 and the first substrate 1420 is reduced, since the first terminal 1450 provides additional space, when the wire is coupled to the first terminal 1450 rather than being coupled to the first substrate 1420, the length of the wire can be increased. That is, even if the overall height of the first camera module is reduced compared to the conventional case, the length of the wire can be maintained the same as the conventional case. In other words, if the length of the wire is the same as the conventional case, the overall height of the first camera module can be reduced.

The second magnet 320-2 and the third magnet 320-3 can be positively magnetized. When the second magnet 320-2 and the third magnet 320-3 are positively magnetized, the AF electromagnetic force can be maximized. Each of the second magnet 320-2 and the third magnet 320-3 can be a four-pole magnet in which the upper part of the inner surface has a different polarity from the lower part of the inner surface and the upper part of the outer surface, and the lower part of the outer surface has the same pole. The upper part of the inner surface and the lower part of the outer surface of the second magnet 320-2 can be N poles, and the lower part of the inner surface and the upper part of the outer surface of the second magnet 320-2 can be S poles. Conversely, the upper part of the inner surface and the lower part of the outer surface of the second magnet 320-2 can be S poles, and the lower part of the inner surface and the upper part of the outer surface of the second magnet 320-2 can be N poles. The upper part of the inner surface and the lower part of the outer surface of the third magnet 320-3 can be N poles, and the lower part of the inner surface and the upper part of the outer surface of the third magnet 320-3 can be S poles.

[0260] The magnet 320 can include an inner surface facing the first coil 220. The inner surface of the magnet 320 can include first to third regions 321, 322, 323. In the initial position where no current is applied to the first coil 220, the first region 321 can face the first portion 221 of the first coil 220. The second region 322 can face the second portion 222 of the first coil 220. The first region 321 can have a first polarity, and the second region 322 can have a second polarity opposite to the first polarity. The third region 323 can be disposed between the first region 321 and the second region 322.

[0261] This embodiment may include a method of adjusting the position of the aperture according to the forward and reverse stroke driving ranges, rather than positioning the aperture at the center with a 4-pole driving magnet. Since the size of the actuator is continuously decreasing and it is difficult to adjust the sizes of the magnet and the coil, this embodiment may be more effective.

[0262] As an example, when optimizing the aperture position under driving conditions of a forward stroke of 320 um and a reverse stroke of -30 um, with the height of the magnet 320 being 1.7 mm, the height of the first region 321 can be set to 0.55 mm, the height of the third region 323 can be set to 0.3 mm, and the height of the second region 322 can be set to 0.85 mm. The area of the first region 321 of the magnet 320 may be different from the area of the second region 322 of the magnet 320.

[0263] The area of the first region 321 of the magnet 320 may be smaller than the area of the second region 322 of the magnet 320. In a variant, the area of the first region 321 of the magnet 320 may be larger than the area of the second region 322 of the magnet 320.

[0264] At the initial position, the distance in the optical axis direction between the upper end of the first portion 221 of the first coil 220 and the lower end of the first region 321 of the magnet 320 (see L1 in FIG. 30) may be 80% or more of the distance in the optical axis direction between the upper end and the lower end of the first portion 221 of the first coil 220 (see L2 in FIG. 30). In this embodiment, the electromagnetic force is lost by about 10% only when the overlapping area between the first portion 221 of the first coil 220 and the first region 321 of the magnet 320 in the direction perpendicular to the optical axis is at least 60% of the area of the first portion 221 of the first coil 220. However, since the position of the first coil 220 is not fixed due to the AF driving unit weight and the posture difference caused by gravity, it is necessary to ensure that L1 / L2 is at least 80%.

[0265] In the initial position, the first portion 221 of the first coil 220 can be overlapped with the first region 321 and the third region 323 of the magnet 320 in a direction perpendicular to the optical axis. In the initial position, the second portion 222 of the first coil 220 can be overlapped with the second region 322 of the magnet 320 in a direction perpendicular to the optical axis. In the initial position, the third portion 223 of the first coil 220 can be overlapped with the second region 322 and the third region 323 of the magnet 320 in a direction perpendicular to the optical axis.

[0266] The length of the inner surface of the magnet 320 in the long side direction can be longer than the length of the first coil 220 in the corresponding direction, and the length of the inner surface of the magnet 320 in the short side direction can be longer than the length of the first coil 220 in the corresponding direction. The length of the inner surface of the magnet 320 in the long side direction can correspond to the length of the second coil 430 in the corresponding direction.

[0267] The magnet 320 can include a first magnet portion 326, a second magnet portion 327, and a neutral portion 328. The first magnet portion 326 can include an N pole and an S pole. The second magnet portion 327 can be disposed below the first magnet portion 326 and include an N pole and an S pole. The neutral portion 328 can be disposed between the first magnet portion 326 and the second magnet portion 327. The first portion 221 of the first coil 220 can be overlapped with the first magnet portion 326 and the neutral portion 328 in a direction perpendicular to the optical axis in the initial position where no current is applied to the first coil 220. The length of the first magnet portion 326 in the optical axis direction can be shorter than the length of the second magnet portion 327 in the optical axis direction.

[0268] FIG. 31 is a graph illustrated to compare the driving linearity between Comparative Example (a) and the present Example (b). The comparative example is an example in which the heights of the first region 321 and / or the first magnet portion 326 and the heights of the second region 322 and / or the second magnet portion 327 are made the same, and the present example is an example in which the heights of the first region 321 and / or the first magnet portion 326 are formed shorter than the heights of the second region 322 and / or the second magnet portion 327. By comparing (a) and (b) of FIG. 34, it can be confirmed that the linearity has increased in (b) which is the present example.
