Abstract
Description
Technical Field
[0001] The present disclosure relates to the field of terminal technology, and in particular to an actuator, a camera module, and an electronic device. Background Art
[0002] With the advancement of science and technology, users have increasingly higher expectations for the camera functions and image quality of terminal devices. To improve image quality, cameras are often equipped with focusing and anti-shake functions. In a related technology, unequal forces are applied to squeeze the liquid lens in the camera, thereby achieving focus adjustment through deformation of the liquid lens. Furthermore, due to the different forces, the deformation of different areas of the liquid lens varies, thereby adjusting the transmission path of the incident light and achieving anti-shake.
[0003] However, in related technologies, anti-shake and focusing are achieved simultaneously through the deformation of the liquid lens. In some cases, it is inevitable that the anti-shake effect is not ideal when the focusing effect is good; or focusing cannot be achieved when the anti-shake effect is good, making it difficult to take into account both the anti-shake effect and the focusing effect of the camera.

[0071] Figure 1 is a top view of a camera module 100 according to an exemplary embodiment. Figure 2 yes Figure 1 A schematic cross-sectional view of the camera module 100 is shown in FIG. Figure 3 yes Figure 1 Schematic diagram of the exploded view of the camera module 100. Figure 1-Figure 3As shown, the camera module 100 may include an actuator 1, a fluid lens 2, and a first lens 3. The first lens 3 is a conventional solid-state lens different from the fluid lens 2. For example, the first lens 3 may include a fixed-focus lens. The fluid in the fluid lens 2 may include, but is not limited to, liquid metal, gel, liquid, gas, and other fluids. When the fluid in the liquid lens 2 is liquid, the fluid lens 2 is a liquid lens. The actuator 1 may include a base 11. The first lens 3 and the fluid lens 2 may be assembled on the base 11. For example, Figure 1 In the embodiment of the present invention, the first lens 3 and the fluid lens 2 can be arranged along the first direction of the base body 11, that is, Figure 2 As shown, the first lens 3 and the fluid lens 2 can be Figure 2 The first direction is aligned with the base 11 and the camera module 100 is aligned with the base 11 in the direction indicated by the arrow A. The first direction may correspond to the optical axis direction of the camera module 100 .
[0072] It is understandable that in order to improve the imaging effect of the camera module 100, the actuator 1 can be used to achieve automatic focus and optical image stabilization to achieve the purpose of clear imaging. Based on this requirement, in the technical solution of the present disclosure, the actuator 1 can also include a stator assembly 12, a focus movable subassembly 13 and an anti-shake subassembly 14, wherein the stator assembly 12 can be assembled in the base 11 and fixedly connected to the base 11, and the focus movable subassembly 13 and the anti-shake subassembly 14 are also arranged in the base 11. Unlike the stator assembly 12, the focus movable subassembly 13 and the anti-shake subassembly 14 can move relative to the base 11 to achieve the purpose of automatic focus and optical image stabilization.
[0073] For example, through the interaction between the stator assembly 12 and the focus movable assembly 13, a force in a first direction can be generated acting on the focus movable assembly 13, and the focus movable assembly 13 can move along the first direction of the base body 11, thereby squeezing the fluid lens 2, and the fluid in the fluid lens 2 flows, thereby achieving the purpose of adjusting the curvature of the fluid lens 2, and thus realizing focusing; and through the interaction between the stator assembly 12 and the anti-shake subassembly 14, the anti-shake subassembly 14 can translate in a plane perpendicular to the first direction, so as to drive the first lens 3 to move, thereby realizing anti-shake of the camera module 100.
[0074] It can be seen from the above embodiments that in the technical solution of the present invention, through the interaction between the focus movable subassembly 13 and the stator assembly 12, the curvature of the fluid lens 2 can be caused to change, thereby achieving the purpose of focusing, and through the interaction between the anti-shake subassembly 14 and the stator assembly 12, the relative position relationship between the first lens 3 and the fluid lens 2 can be changed by adjusting the position of the first lens 3, thereby achieving the purpose of optical image stabilization. The focus function and the anti-shake function of the camera module 100 can be realized independently of each other. Compared with related technologies, the mutual influence between the focusing process and the anti-shake process can be avoided, which is beneficial to improving image quality.
[0075] In the technical solution of the present disclosure, the focus actuator assembly 13 can be arranged outside the stator assembly 12 around the first direction, while the anti-shake subassembly 14 can be arranged inside the stator assembly 12 around the first direction. Moreover, the first lens 3 is arranged on the side of the anti-shake subassembly 14 facing away from the stator assembly 12. Based on this, the focus actuator assembly 13, stator assembly 12, anti-shake subassembly 14, and first lens 3 are assembled in a multi-layer "collar" form, which helps to reduce the overall height of the camera module 100 and facilitates the internal layout of the electronic equipment of the camera module 100. Of course, in the embodiments provided in the present disclosure, the "ring" form is used as an example for illustration. In other embodiments, the focus movable subassembly 13 and the stator assembly 12 may be arranged along the first direction, and the anti-shake subassembly 14 may be arranged on the inner side of the stator assembly 12, or the focus movable subassembly 13 may be arranged on the outer side of the stator assembly 12, and the anti-shake subassembly 14 and the stator assembly 12 may be arranged along the first direction. The overall design is to achieve the movement of the focus movable subassembly 13 in the first direction and the translation of the anti-shake subassembly 14 in a plane perpendicular to the optical axis. The present disclosure is not limited to this. Similarly, in some other embodiments, the first lens 3 and the anti-shake subassembly 14 may also be arranged along the first direction. The present disclosure is not limited to this. In the embodiments of the present disclosure, the interaction between the same stator assembly 12 and the focus movable subassembly 13 and the anti-shake subassembly 14 is used as an example for illustration. In some other possible embodiments, the focus movable subassembly 13 and the anti-shake subassembly 14 may also interact with different stator assemblies 12.
[0076] Regarding the interaction between the stator assembly 12 and the focus actuator assembly 13, and the interaction between the stator assembly 12 and the anti-shake subassembly 14, for example, the stator assembly 12 may include a first acting member, the focus actuator assembly 13 may include a second acting member, and the anti-shake subassembly 14 may include a third acting member. Through the interaction between the first acting member and the second acting member, the focus actuator assembly 13 is pushed to move in the first direction. Through the interaction between the first acting member and the second acting member, the anti-shake subassembly 14 is translated in a plane perpendicular to the first direction. Among them, the first acting member, the second acting member, and the third acting member can include various structures, which will be exemplified below:
[0077] In some possible embodiments, the first acting member may include a stator magnet, and the second acting member of the focus actuator assembly 13 may include a focus coil 131. The focus coil 131 and the fluid lens 2 are arranged along the first direction. After receiving the focus instruction, the camera module 100 can energize the focus coil 131. The focus coil 131 can interact with the stator magnet of the stator assembly 12 to generate a force along the first direction. Through this force, the focus actuator assembly 13 is pushed toward the fluid lens 2 and squeezes the fluid lens 2, causing the fluid lens 2 to deform and change the curvature of the fluid lens 2, thereby achieving the purpose of focusing. The third active part of the anti-shake subassembly 14 may include an anti-shake coil. The anti-shake subassembly 14 is also assembled with the first lens 3. When the camera module 100 receives an anti-shake command, the anti-shake coil can be energized, and the anti-shake coil interacts with the stator magnet of the stator assembly 12 to generate a force perpendicular to the first direction. This force can push the anti-shake subassembly 14 relative to the base 11 to translate in a plane perpendicular to the first direction, adjust the relative position relationship between the first lens 3 and the fluid lens 2, so as to compensate for the image blur caused by the user shaking during shooting, thereby achieving the purpose of optical anti-shake.
[0078] In other possible embodiments, the first acting part of the stator assembly 12 may also include a stator coil, the second acting part of the focusing movable subassembly 13 may include a focusing magnet, and the third acting part of the anti-shake subassembly 14 may include an anti-shake magnet. By reasonably setting the direction of the magnetic flux lines of the focusing magnet, the N pole and S pole of the anti-shake magnet, and the direction of the current in the stator coil, the focusing movable subassembly 13 can be pushed to move along the first direction when the stator coil interacts with the focusing magnet, and the anti-shake subassembly 14 can be pushed to translate in a plane perpendicular to the first direction through the interaction between the stator coil and the anti-shake magnet.
[0079] For example, the stator assembly 12 may include: a first acting member and an annular bracket 121 , wherein the annular bracket 121 is fixedly connected to the base body 11 ; the first acting member is disposed on the annular bracket 121 along a circumferential direction of the annular bracket 121 .
[0080] For example, the focusing actuator assembly may include: a second acting member, a first mounting seat 132 and a first connecting piece 133. The first mounting seat 132 may be arranged in the seat body 11. The first mounting seat 132 may include a first through-portion 1321. The stator assembly 12 may be arranged in the first through-portion 1321. The second acting member may be arranged on the outside of the first mounting seat 132 along the circumference of the first mounting seat 132; the first connecting piece 133 is connected to the first mounting seat 132 along the first direction, and the first connecting piece 133 is used to connect to the fluid lens.
[0081] For example, the anti-shake subassembly 14 may include a third actuator and a second mounting seat 145. The second mounting seat 145 may be disposed within the base 11. The second mounting seat 145 may be disposed inside the stator assembly 12. The second mounting seat 145 may include a second through-portion 1451. The first lens 3 may be disposed within the second through-portion 1451 and assembled with the second mounting seat 145. The third actuator may be disposed along the circumference of the second mounting seat 145 on a side of the second mounting seat 145 facing the stator assembly 12; alternatively, a plurality of third actuators may be disposed along the circumference of the second mounting seat 145 at intervals on the side of the second mounting seat 145 facing the stator assembly 12. For example, the anti-shake subassembly 14 can also include a second connecting piece 146 and a suspension wire 147, wherein the second connecting piece 146 is connected to the first end of the second mounting seat 145, one end of the suspension wire 147 can be connected to the second connecting piece 146, and the other end can be connected to the second end of the seat body 11, and the first end and the second end are arranged along the first direction of the seat body 11.
[0082] To further illustrate the embodiments of the present disclosure, the following description will use an example in which the first active member includes a stator magnet, the second active member includes a focus coil, and the third active member includes an anti-shake coil. For example, there can be multiple first active members (greater than or equal to two), meaning there can be multiple stator magnets, with the multiple stator magnets being disposed circumferentially around the annular support 121. For example, there can be four first active members, meaning there can be four stator magnets in this example.
[0083] like Figure 4 As shown, the stator assembly 12 may include an annular bracket 121, and the number of stator magnets is 4, which may include a first stator magnet 122, a second stator magnet 123, a third stator magnet 124 and a fourth stator magnet 125. The first stator magnet 122, the second stator magnet 123, the third stator magnet 124 and the fourth stator magnet 125 are arranged on the annular bracket 121 along the axial direction of the annular bracket 121, the focus moving subassembly 13 is located on the outside of the annular bracket 121, and the anti-shake subassembly 14 is located on the inside of the annular bracket 121. Based on this, as Figure 5As shown, the focusing coil 131 can be located on the outside of the annular bracket 121, while the anti-shake coil is located on the inside of the annular bracket 121. The first stator magnet 122, the second stator magnet 123, the third stator magnet 124 and the fourth stator magnet 125 all have a first polarity on the side facing the anti-shake subassembly 14, and a second polarity on the side facing the focusing rotor assembly 13.
[0084] Among them, the first stator magnet 122, the second stator magnet 123, the third stator magnet 124, and the fourth stator magnet 125 can respectively interact with the focus coil 131 to generate a force along the first direction, thereby realizing the movement of the focus actuator assembly 13. The first stator magnet 122, the second stator magnet 123, the third stator magnet 124, and the fourth stator magnet 125 can also respectively interact with the anti-shake coil to generate a force perpendicular to the first direction, thereby promoting the translation of the anti-shake subassembly 14. In the embodiments provided in the present disclosure, only the stator assembly 12 including the first stator magnet 122, the second stator magnet 123, the third stator magnet 124, and the fourth stator magnet 125 is used as an example for description. In other embodiments, the stator assembly 12 may also include other numbers of stator magnets, and the present disclosure is not limited to this.
[0085] For example, the annular bracket 121 may include an annular magnetic bracket, and since the first stator magnet 122, the second stator magnet 123, the third stator magnet 124 and the fourth stator magnet 125 are arranged at intervals on the annular magnetic bracket, the magnetism of each stator magnet can extend toward both ends, so that the part of the annular magnetic bracket where the stator magnet is not set is also magnetic, and can interact with the focusing coil 131, thereby increasing the uniformity of the force acting on the focusing rotor assembly 13 along the first direction.
[0086] In some possible embodiments, the annular bracket 121 may include a plurality of hollow areas 1211 spaced apart along the circumferential direction, and the plurality of hollow areas 1211 are arranged in a one-to-one correspondence with the plurality of stator magnets. For example, the plurality of hollow areas 1211 may be arranged in a one-to-one correspondence with the first stator magnet 122, the second stator magnet 123, the third stator magnet 124, and the fourth stator magnet 125, so as to avoid the presence of spacers between the stator magnets and the anti-shake coil, which affects the anti-shake effect. When the stator assembly 12 includes another number of stator magnets, the stator magnets may be arranged in a one-to-one correspondence with the hollow areas 1211 on the annular bracket 121.
[0087] In order to facilitate understanding of the technical solution of the present disclosure, the following will take the first polarity as the S pole and the second polarity as the N pole as an example to illustrate the implementation of the focus function and the anti-shake function.
[0088] With respect to the focusing function of the camera module 100, since the side of each stator magnet facing the focusing assembly can be the N pole, and the side facing the anti-shake subassembly 14 can be the S pole, the magnetic flux lines of the first stator magnet 122, the second stator magnet 123, the third stator magnet 124 and the fourth stator magnet 125 are all directed from the side corresponding to the magnet facing the focusing rotor impedance to the side facing the anti-shake subassembly 14, the central axis direction of the focusing coil 131 is parallel to the first direction, and the polarity arrangement direction of the first stator magnet 122, the second stator magnet 123, the third stator magnet 124 and the fourth stator magnet 125 is perpendicular to the first direction, wherein the polarity arrangement direction is the arrangement direction of the N pole and the S pole of the stator magnet, and the focusing coil 131 can be the direction of the conductive wire around the central axis (i.e. Figure 5 The focus coil 131 is formed by multiple turns (in the direction indicated by arrow B in the center), so that the current flowing through the focus coil 131 flows around the central axis of the focus coil 131. Based on this, when a focus command is received, the focus coil 131 is energized. According to the left-hand rule, the focus coil 131 and the first, second, third, and fourth stator magnets 122, 123, 124, and 125 can each interact to generate an upward force in the first direction, thereby pushing the focus actuator assembly 13 as a whole toward the fluid lens 2, thereby squeezing the fluid lens 2 and adjusting the curvature of the fluid lens 2 to achieve the purpose of focusing. Alternatively, by adjusting the direction of the current flowing through the focus coil 131, the focus coil 131 and the first, second, third, and fourth stator magnets 122, 123, 124, and 125 can each interact to generate a downward force in the first direction, thereby resetting the focus actuator assembly 13 and restoring the deformation of the fluid lens 2.
[0089] like Figure 6As shown, the focusing rotor assembly 13 can also include a first mounting seat 132 and a first connecting piece 133. The first mounting seat 132 can be arranged in the seat body 11. The first mounting seat 132 can include a first through-portion 1321. The stator assembly 12 can be arranged in the first through-portion 1321. The focusing coil 131 can be arranged on the outside of the first mounting seat 132 along the circumference of the first mounting seat 132, so that the focusing coil 131 can be arranged corresponding to the first stator magnet 122, the second stator magnet 123, the third stator magnet 124 and the fourth stator magnet 125. Of course, in order to strengthen the force generated by the interaction between the focusing coil 131 and the first stator magnet 122, the second stator magnet 123, the third stator magnet 124 and the fourth stator magnet 125, the first mounting seat 132 can also include multiple openings, and the first stator magnet 122, the second stator magnet 123, the third stator magnet 124 and the fourth stator magnet 125 can be respectively arranged corresponding to the corresponding openings, so that there are no other obstacles between the focusing coil 131 and the first stator magnet 122, the second stator magnet 123, the third stator magnet 124 and the fourth stator magnet 125, thereby enhancing the force that pushes the focusing actuator assembly 13 to move along the first direction.
[0090] The first connecting piece 133 can be arranged on the first mounting seat 132 along the first direction, and the first connecting piece 133 can be used to connect with the fluid lens 2, so that when the focus actuator assembly 13 moves toward the fluid lens 2, the first connecting piece 133 can act on the fluid lens, causing the curvature of the fluid lens 2 to change. For example, Figure 7 As shown, the fluid lens 2 may include a fixed frame 21, a diaphragm 22 and a movable piece 23. The diaphragm 22 is connected to the fixed frame 21, and liquid may be provided between the diaphragm 22 and the fixed frame 21. The movable piece 23 is connected to the diaphragm 22, and the movable piece 23 is also connected to the first connecting piece 133. When the first connecting piece 133 moves toward the fluid lens 2, the first connecting piece 133 can push the movable piece 23 to move, causing the liquid between the fixed frame 21 and the diaphragm 22 to flow, thereby adjusting the curvature of the fluid lens 2.
[0091] Of course, after the focus actuator assembly 13 is focused, or after the shooting is completed, the focus actuator assembly 13 needs to be reset so that the focus actuator assembly 13 and the stator assembly 12 can interact and focus again. Therefore, in order to reset the focus actuator assembly 13, the actuator 1 can also include a first spring clip 15 and a second spring clip 16. The first spring clip 15 can be arranged between the base body 11 and the first mounting seat 132 along the circumference of the first mounting seat 132, and the first spring clip 15 and the first mounting seat 132 and the base body 11 can be fixedly connected, for example, by welding; similarly, the second spring clip 16 can be arranged between the base body 11 and the first mounting seat 132 along the circumference of the first mounting seat 132, and the first spring clip 16 can be fixedly connected, for example, by welding. Among them, the first spring clip 15 and the second spring clip 16 are arranged along the first direction, and there is a certain spacing distance between the first spring clip 15 and the second spring clip 16 in the first direction. Based on this, the focus actuator assembly 13 can be suspended between the stator assembly 12 and the base 11 through the action of the first spring piece 15 and the second spring piece 16. When the focus actuator assembly 13 moves along the first direction toward the fluid lens 2, the first spring piece 15 and the second spring piece 16 will cause deformation. Therefore, after the focus coil 131 is powered off, the focus coil 131 is not affected by external forces and can be reset under the action of the first spring piece 15 and the second spring piece 16. Moreover, due to the action of the first spring piece 15 and the second spring piece 16, the focus actuator assembly 13 can be reset to the same position after each focusing. Moreover, the action of the first spring piece 15 and the second spring piece 16 can limit the movement of the focus actuator assembly 13 within a plane perpendicular to the first direction.
[0092] Regarding the anti-shake function of the camera module 100, as an exemplary illustration, the anti-shake subassembly 14 may include an anti-shake coil that interacts with the stator magnet of the stator assembly 12. Still taking the embodiment provided in the present disclosure, the stator magnet includes the first stator magnet 122, the second stator magnet 123, the third stator magnet 124 and the fourth stator magnet 125 as an example. Accordingly, the anti-shake coil may include the first anti-shake coil 141, the second anti-shake coil 142, the third anti-shake coil 143 and the fourth anti-shake coil 144, and the first anti-shake coil 141 is arranged corresponding to the first stator magnet 122, the second anti-shake coil 142 is arranged corresponding to the second stator magnet 123, the third anti-shake coil 143 is arranged corresponding to the third stator magnet 124, and the fourth anti-shake coil 144 is arranged corresponding to the fourth stator magnet 125, and the central axis direction of each anti-shake coil is perpendicular to the first direction, that is, the central axis direction of each anti-shake coil (i.e. Figure 5The direction indicated by the arrow C in the middle is parallel to the polarity arrangement direction of the corresponding stator magnet; and the current flowing through each anti-shake coil flows in a direction surrounding the central axis of the anti-shake coil. Based on this, after any anti-shake coil is energized, a magnetic field can be generated around the anti-shake coil. By controlling the direction of the current in each anti-shake coil, the anti-shake coil can be made to have an S pole or a N pole on the side facing the stator magnet 122. Since the first stator magnet 122, the second stator magnet 123, the third stator magnet 124, and the fourth stator magnet 125 are all S poles on the side facing the anti-shake subassembly 14, a repulsive force or an attractive force is generated between the anti-shake coil and the stator magnet, pushing the anti-shake subassembly 14 away from the stator magnet corresponding to any anti-shake coil in a plane perpendicular to the first direction, or attracting the anti-shake subassembly 14 in a plane perpendicular to the first direction, causing it to translate toward the stator magnet corresponding to any anti-shake coil. For example, the magnitude and direction of the force acting on the anti-shake subassembly 14 can be adjusted by controlling the power on, power off, current direction and current magnitude of the anti-shake coils in the magnetic field of multiple stator magnets, so that compensation can be performed in all directions, thereby improving the practicality of the anti-shake function.
[0093] Of course, in the above embodiment, only the one-to-one correspondence between the anti-shake coil and the stator magnet is used as an example for description. In other embodiments, a single stator magnet may correspond to multiple anti-shake coils, and the direction of the current flowing through the multiple anti-shake coils corresponding to the same stator magnet is the same, so that the direction of the generated force is the same. In the above embodiment, the first stator magnet 122 and the third stator magnet 124 are arranged opposite each other, and the second stator magnet 123 and the fourth stator magnet 125 are arranged opposite each other, and the polarity arrangement directions of the two stator magnets are orthogonal to each other. Based on this, a force parallel to a plane perpendicular to the first direction and orthogonal to each other can be generated, which can drive the anti-shake subassembly 14 to translate in various directions within the plane perpendicular to the first direction, thereby achieving shake compensation in various directions. In some other possible embodiments, there may be at least one group of stator magnets with orthogonal polarity arrangement directions among the multiple stator magnets, thereby generating a force parallel to and orthogonal to the plane perpendicular to the first direction, and also achieving jitter compensation in all directions. The specific design can be as needed, and the present disclosure does not limit this.
[0094] like Figure 8As shown, the anti-shake subassembly 14 may include a second mounting seat 145, which may be arranged in the seat body 11, and the second mounting seat 145 may be arranged on the inner side of the stator assembly 12, and the second mounting seat 145 may include a second through-portion 1451, and the first lens 3 is arranged in the second through-portion 1451 and assembled with the second mounting seat 145, and the first anti-shake coil 141, the second anti-shake coil 142, the third anti-shake coil 143 and the fourth anti-shake coil 144 can be arranged on the outer side of the second mounting seat 145 along the circumferential interval of the second mounting seat 145, so that the first anti-shake coil 141, the second anti-shake coil 142, the third anti-shake coil 143 and the fourth anti-shake coil 144 can respectively correspond to the stator magnets in the stator assembly 12. For example, the anti-shake subassembly 14 may further include a second connecting piece 146 and a suspension wire 147, wherein the second connecting piece 146 is connected to the first end of the second mounting seat 145, one end of the suspension wire 147 may be connected to the second connecting piece 146, and the other end may be connected to the second end of the seat body 11, the first end and the second end are arranged along a first direction of the seat body 11, so that the suspension wire 147 can be arranged along the first direction, and the stiffness of the suspension wire 147 in the first direction is greater than the stiffness of the suspension wire 147 in the second direction, and the second direction is perpendicular to the first direction. Therefore, when the anti-shake subassembly 14 interacts to generate a force, since the stiffness of the suspension wire 147 in the direction perpendicular to the first direction is weaker, the anti-shake subassembly 14 can drive the first lens 3 to move in a plane parallel to the second direction, and since the stiffness of the suspension wire 147 in the first direction is stronger, the movement of the anti-shake subassembly 14 and the first lens 3 in the first direction can be reduced, thereby reducing interference with the focusing function.
[0095] To achieve closed-loop control of the anti-shake function, in the embodiments provided herein, the actuator 1 may further include a Hall magnet and a Hall sensor. The Hall magnet and the Hall sensor may be provided in a one-to-one correspondence, and one of the Hall sensor and the Hall magnet may be connected to the anti-shake subassembly 14, while the other may be connected to the base 11. Subsequently, based on the change in magnetic field intensity detected by the Hall sensor, the position and displacement of the anti-shake subassembly 14 can be calculated, thereby determining whether shake compensation has been completed. For example, in the embodiments provided herein, the Hall magnet may include a first Hall magnet 17 and a second Hall magnet 18. Both the first Hall magnet 17 and the second Hall magnet 18 may be connected to the second mounting base 145 of the anti-shake subassembly 14. The polarity of the first Hall magnet 17 and the second Hall magnet 18 may be arranged parallel to the first direction, and the extension directions of the first Hall magnet 17 and the second Hall magnet 18 may be orthogonal. In this way, the Hall sensor can detect the displacement of the anti-shake subassembly 14 in the orthogonal direction to obtain the coordinate position of the anti-shake subassembly 14.
[0096] The Hall sensor may further include a first Hall sensor 19 and a second Hall sensor 110 connected to the base 11. The first Hall magnet 17 is provided corresponding to the first Hall sensor 19, and the second Hall magnet 18 is provided corresponding to the second Hall sensor 110. When the anti-shake subassembly 14 moves, the relative positional relationship between the first Hall magnet 17 and the first Hall sensor 19, and between the second Hall magnet 18 and the second Hall sensor 110 changes. The first Hall sensor 19 and the second Hall sensor 110 can change according to the detected magnetic field strength. Based on this change in magnetic field strength, the real-time position of the anti-shake subassembly 14 can be obtained, thereby achieving displacement control of the anti-shake subassembly 14 and improving the accuracy of the anti-shake function. In order to reduce the interference of the Hall magnet on the stator assembly 12, the actuator 1 may also include a shielding cover, the Hall magnet may be arranged in the shielding cover, and the shielding cover and the Hall magnet may be connected to the base 11 or the anti-shake subassembly 14. For example, in an embodiment of the present disclosure, the shielding cover may include a first shielding cover 120 and a second shielding cover 130, the first shielding cover 120 and the second shielding cover 130 are both connected to the second mounting seat 145, the first Hall magnet 17 may be arranged in the first shielding cover 120 and connected to the second mounting seat 145, and the second Hall magnet 18 may be arranged in the second shielding cover 130 and connected to the second mounting seat 145.
[0097] It should be noted that in the above embodiment, the actuator 1 is described as including a first Hall magnet 17, a second Hall magnet 18, a first Hall sensor 19, and a second Hall sensor 110. In other embodiments, the actuator 1 may also include other numbers of Hall magnets and other numbers of Hall sensors, and the Hall sensors and Hall magnets are arranged in a one-to-one correspondence. When the actuator 1 includes multiple Hall magnets, the polarity arrangement directions of the multiple Hall magnets can all be parallel to the first direction, and the extension directions of at least two of the Hall magnets can be orthogonal. In this way, the displacement of the anti-shake subassembly 14 can be detected in the orthogonal directions to obtain the coordinate position of the anti-shake subassembly 14. In the above embodiment, in order to detect the displacement of the anti-shake subassembly 14 in an orthogonal direction, a technical solution is proposed in which the polarity arrangement directions of the multiple Hall magnets can all be parallel to the first direction, and the extension directions of at least two of the Hall magnets can be orthogonal. In other embodiments, the polarity arrangement direction of each of the multiple Hall magnets included in the actuator 1 can be perpendicular to the first direction, and the polarity arrangement directions of at least two of the Hall magnets can be perpendicular. In this way, the displacement of the anti-shake subassembly 14 can also be detected in the orthogonal direction. In the above embodiment, the Hall magnet is connected to the second mounting base 145 and the Hall sensor is connected to the base 11 as an example. In other embodiments, the Hall magnet can also be connected to the base 11, for example, the Hall magnet can be directly fixedly connected to the base 11 or indirectly fixedly connected to the base 11. For example, the Hall magnet can be connected to the annular bracket 121, the annular bracket 121 is connected to the base 11, and the Hall sensor is connected to the second mounting base 145. This is not limited in the present disclosure.
[0098] The above example is described using the example where the first active member includes a stator magnet, the second active member includes a focusing coil, and the third active member includes an anti-shake coil. For the embodiment where the first active member includes a stator coil, the second active member includes a focusing magnet, and the third active member includes an anti-shake magnet, the stator coil of the stator assembly 12 can be arranged along the circumference of the annular bracket 121 on the side of the annular bracket 121 facing the focusing movable subassembly 13, the focusing magnet can be arranged along the circumference of the first mounting seat 132 on the outside of the stator coil, and the anti-shake magnet can be arranged along the circumference of the second mounting seat 145 on the inside of the stator coil. The focusing magnet can include an annular magnet or multiple block magnets arranged around the outside of the stator coil, and the anti-shake subassembly 14 can include multiple anti-shake magnets arranged around the inside of the stator coil. Based on this, by properly arranging the north and south poles of the focus magnet, the north and south poles of the anti-shake magnet, and the direction of the current in the stator coil, the focus actuator assembly 13 can be driven to move in a first direction to squeeze the fluid lens 2, and the anti-shake subassembly 14 can be driven to move in a plane perpendicular to the first direction. In this embodiment, the other structures of the focus actuator assembly 13 and the anti-shake subassembly 14 can be referred to in the previous embodiments and will not be detailed here.
[0099] In each of the above embodiments, the base 11 may include a cover 111 and a base plate 112 assembled with the cover 111. The cover 111 may include a mounting cavity 1112, within which the stator assembly 12, the focus actuator assembly 13, and the anti-shake assembly 14 are disposed. The cover 111 may also be used to connect to the fluid lens 2. The base plate 112 may be assembled with the cover 111 to seal one end of the mounting cavity 1112. The base plate 112 may also be connected to the stator assembly 12 to secure the stator assembly 12. For example, the base plate 112 may include mounting posts 1122, and the annular support 121 of the stator assembly 12 may include mounting holes. The mounting holes may be assembled with the mounting posts 1122, thereby assembling the base plate 112 with the stator assembly 12. Of course, in other embodiments, the base plate 112 may include mounting holes, and the annular support 121 of the stator assembly 12 may include mounting posts 1122, but this disclosure is not limited thereto.
[0100] For example, the fluid lens 2 can be connected to the housing 111. The housing 111 can include multiple fixing platforms 1111 disposed on a side of the housing 111 facing away from the substrate 112. These fixing platforms 1111 can be arranged circumferentially around the mounting cavity 1112 and connected to the fixing frame 21 of the fluid lens 2 to facilitate assembly of the fluid lens 2 with the housing 11. The combined action of these multiple fixing platforms 1111 can improve the uniformity of the fluid lens 2's handling and prevent deformation of the fluid lens 2 during installation. The first lens 3 can be positioned adjacent to the substrate 112. The substrate 112 includes a mounting groove 1121, within which a Hall effect sensor that interacts with the Hall effect magnet on the anti-shake subassembly 14 can be positioned. Of course, if the anti-shake subassembly 14 includes a Hall effect sensor, the Hall effect magnet and corresponding shielding cover can be secured via the mounting groove 1121. The specific design can be customized and is not limited in this disclosure. In order to supply power to the focusing coil 131 and the anti-shake coil, the substrate 112 may include a plastic cover (not shown) and a metal terminal (not shown) arranged on the plastic cover. The metal terminal can be directly or indirectly connected to the focusing coil 131 and the anti-shake coil to realize power supply or power off, and the plastic cover can be used for insulation to reduce the risk of short circuit. The mounting groove 1121 and the mounting column 1122 can both be arranged on the plastic cover.
[0101] Based on the technical solution of the present disclosure, the present disclosure also provides an electronic device, which may include one or more camera modules 100 described in the above embodiments. Image information can be obtained through the camera module 100, and since the focusing function and the anti-shake function can be implemented independently, the interference between the two functions can be reduced.
[0102] Other embodiments of the present disclosure will readily occur to those skilled in the art after considering the specification and practicing the disclosure herein. This disclosure is intended to cover any variations, uses, or adaptations of the present disclosure that follow the general principles of the present disclosure and include common knowledge or customary techniques in the art not disclosed herein.

[0103] It should be understood that the present disclosure is not limited to the exact structures that have been described above and shown in the drawings, and that various modifications and changes can be made without departing from the scope thereof. The scope of the present disclosure is limited only by the appended claims.
