[0064] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0065] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate directions or positional relationships based on the attached Figure 1 The orientation or positional relationship shown is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0066] It should be understood that in this application, "electrical connection" can be understood as physical contact and electrical conduction between components; it can also be understood as a form of connection between different components in the circuit structure through physical lines such as printed circuit board (PCB) copper foil or wires that can transmit electrical signals. "Communication connection" can refer to electrical signal transmission, including wireless communication connection and wired communication connection. Wireless communication connection does not require a physical medium and does not belong to a connection relationship that limits the product structure. "Connection" and "connected" can both refer to a mechanical connection relationship or a physical connection relationship, that is, A is connected to B or A is connected to B, which can mean that there is a fastening component (such as screws, bolts, rivets, etc.) between A and B, or A and B are in contact with each other and A and B are difficult to separate.

[0067] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meanings as commonly understood by those of ordinary skill in the art.

[0068] Optical Image Stabilization (OIS) relies on the structure and movement of special lenses or photosensitive elements to minimize image instability caused by operator shaking during use.

[0069] Auto Focus: (Auto Focus, AF), uses the principle of light reflection from an object. The reflected light is received by the sensor on the camera (module), processed by a computer, and drives the electric focus device to focus.

[0070] The four magnets distributed on the four sides of the driving device for implementing shake correction in the related art generate magnetic field interference with each other. In a multi-camera module environment, the camera modules using the four-sided magnet solution will also generate magnetic field interference with each other. To address this problem, the method of reducing the number of magnets in some camera modules is usually adopted, but this method will lead to insufficient actuation force in some directions.

[0071] Therefore, the present application provides an actuator to utilize the camera module and electronic device of the actuator. By arranging compensating magnets in the driving components in other directions, power compensation is performed in the direction with fewer magnets, thereby avoiding the problem of insufficient driving force caused by the reduction in the number of magnets. This ensures that the camera module using the actuator does not have the problem of magnetic field interference, and the number of magnets cannot be reduced in multi-module scenarios. The actuator has good market application prospects.

[0072] The electronic device provided by the present application. Specifically, the electronic device can be any of various types of computer system devices that are mobile or portable and perform wireless communication. Specifically, the electronic device can be a mobile phone or smart phone (e.g., a phone based on iPhone TM, a phone based on Android TM), a portable game device (e.g., Nintendo DS TM, PlayStation Portable TM, Gameboy Advance TM, iPhone TM), a laptop, a PDA, a portable Internet device, a music player, and a data storage device, other handheld devices, and such as headphones, etc. The electronic device can also be other wearable devices that need to be charged (e.g., a head-mounted device (HMD) such as an electronic bracelet, an electronic necklace, an electronic device, or a smart watch).

[0073] The electronic device can also be any one of a plurality of electronic devices, including but not limited to cellular phones, smart phones, other wireless communication devices, personal digital assistants, audio players, other media players, music recorders, video recorders, other media recorders, radios, medical devices, vehicle transportation instruments, calculators, programmable remote controls, pagers, laptop computers, desktop computers, printers, netbook computers, personal digital assistants (PDAs), portable multimedia players (PMPs), Moving Picture Experts Group (MPEG-1 or MPEGG-2) Audio Layer 3 (MP3) players, portable medical devices, and digital cameras and combinations thereof.

[0074] In some cases, the electronic device can perform multiple functions (e.g., play music, display video, store pictures, and receive and send phone calls). If desired, the electronic device can be a device such as a cellular phone, a media player, other handheld device, a wristwatch device, a pendant device, a handset device, or other compact portable device.

[0075] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0076] On the one hand, combined with Figure 1 , Figure 2 As shown, this embodiment provides an actuator, which includes: a base member 1 , a first bracket member 2 and at least two driving components 3 .

[0077] The first bracket member 2 is movably disposed above the base member 1 , and the first bracket member 2 can move relative to the base member 1 along a first direction X and a second direction Y respectively. The first direction X and the second direction Y form a preset angle α, wherein 0<α<180°.

[0078] Exemplarily, the value of the preset angle α between the first direction X and the second direction Y is, for example, 10°, 30°, 45°, 60°, 90°, 100°, 120°, 150°, 160°, 175°, etc. Optionally, the preset angle α between the first direction X and the second direction Y=90°.

[0079] At least two driving components 3 are used to drive the first bracket component 2 to move along the first direction X and the second direction Y respectively.

[0080] In some possible implementations, the number of the driving components 3 includes but is not limited to two, three, four, etc. Among them, one driving component 3 can be used to realize the movement of the first bracket member 2 along the first direction X, and two or more driving components 3 can also be used to realize the movement of the first bracket member 2 along the first direction X. Similarly, one driving component 3 can be used to realize the movement of the first bracket member 2 along the second direction Y, and two or more driving components 3 can also be used to realize the movement of the first bracket member 2 along the second direction Y.

[0081] Each driving component 3 includes a main driving module, and at least one driving component 3 also includes a compensation driving module; the driving direction of the main driving module in the same driving component 3 is one of the first direction X and the second direction Y, and the driving direction of the compensation driving module is the other of the first direction X and the second direction Y.

[0082] Exemplarily, the driving direction of the main driving module is arranged along the first direction X, and the driving direction of the compensation driving module is arranged along the second direction Y. Thus, the driving component 3 can rely on the main driving module to provide the power for the first bracket 2 to move along the first direction X, and rely on the compensation driving module to provide the power for the first bracket 2 to move along the second direction Y. By using the driving component 3, it is possible to provide power compensation for the driving component 3 in the second direction Y, and the number of magnets of the main driving module in the second direction Y can be reduced accordingly, which can reduce magnetic field interference on the one hand, and reduce the number of magnets on the other hand, which is conducive to reducing costs and reducing the mass of the actuator.

[0083] In another exemplary embodiment, the driving direction of the main driving module is arranged along the second direction Y, and the driving direction of the compensation driving module is arranged along the first direction X. Thus, the driving component 3 can rely on the main driving module to provide the power for the first bracket 2 to move along the second direction Y, and rely on the compensation driving module to provide the power for the first bracket 2 to move along the first direction X. By using the driving component 3, power compensation can be provided for the driving component 3 in the first direction X, and the number of magnets of the main driving module in the first direction X can be reduced accordingly, which can reduce magnetic field interference on the one hand, and reduce the number of magnets on the other hand, which is conducive to reducing costs and reducing the mass of the actuator.

[0084] In the actuator of the present application, the first bracket member can move relative to the base member along the first direction and the second direction respectively under the drive of the driving component, which can be suitable for realizing optical image stabilization of the camera module; the driving component relies on the main driving module to drive the first bracket member to move relative to the base member; wherein, at least one driving component is also provided with a compensation driving module, which can perform power compensation on the driving component in another direction, so that when the driving force in that direction is insufficient due to the reduction in the number of magnets, the compensation driving module arranged in the other driving component can be used to compensate for the power, thereby avoiding the problem of insufficient driving force caused by the reduction in the number of magnets.

[0085] Combination Figure 1 , 2 As shown, in some embodiments, each driving component 3 includes a main magnetic component 301 and a main control coil 302 coupled with a magnetic field, the main magnetic component 301 is located on one of the base component 1 and the first bracket component 2, and the main control coil 302 is located on the other of the base component 1 and the first bracket component 2.

[0086] Exemplarily, the main magnet component 301 is located on the base component 1, and the main control coil 302 is located on the first bracket component 2. Alternatively, the main magnet component 301 is located on the first bracket component 2, and the main control coil 302 is located on the base component 1.

[0087] It should be noted that the magnetic field coupling between the main magnet 301 and the main control coil 302 can be understood as that the magnetic field generated by the main magnet 301 at least partially overlaps with the magnetic field generated by the main control coil 302, so that the two magnetic fields generate an attractive force or a repulsive force. Among them, the magnetic field generated by the main control coil 302 is affected by the current passed therein, so that the interaction force between the two magnetic fields can be controlled, that is, by controlling the current of the main control coil 302, the magnetic field of the main control coil 302 can be changed, thereby adjusting the interaction force between the main magnet 301 and the main control coil 302. When one of the two is fixed in position, the other will be pulled or pushed by the reaction force, thereby producing the desired movement effect.

[0088] At least one of the at least two driving components 3 also includes a compensation magnet 303 and a compensation control coil 304 coupled with a magnetic field, the compensation magnet 303 is located on one of the base component 1 and the first bracket component 2, and the compensation control coil 304 is located on the other of the base component 1 and the first bracket component 2.

[0089] Optionally, the drive assembly 3 having the compensation magnet 303 may be all the drive assemblies 3, or one or two of the drive assemblies 3, etc. The positions of the compensation magnet 303 and the compensation control coil 304 may be that the compensation magnet 303 is located on the base member 1, and the compensation control coil 304 is located on the first bracket member 2, or that the compensation magnet 303 is located on the first bracket member 2, and the compensation control coil 304 is located on the base member 1.

[0090] It should be noted that the positions of the compensation magnet 303 and the main magnet 301 in a single drive component 3 may be the same or different. For example, the compensation magnet 303 and the main magnet 301 in a single drive component 3 are both located on the base component 1, or are both located on the first bracket component 2. For another example, the compensation magnet 303 and the main magnet 301 in a single drive component 3 are respectively located on the base component 1 and the first bracket component 2, which includes the compensation magnet 303 being located on the base component 1 and the main magnet 301 being located on the first bracket component 2, and also includes the compensation magnet 303 being located on the first bracket component 2 and the main magnet 301 being located on the base component 1.

[0091] The positions of the compensation control coil 304 and the main control coil 302 in a single drive component 3 may be the same or different. For example, the compensation control coil 304 and the main control coil 302 in a single drive component 3 are both located on the base member 1, or both located on the first bracket member 2. For another example, the compensation control coil 304 and the main control coil 302 in a single drive component 3 are respectively located on the base member 1 and the first bracket member 2, which includes the compensation control coil 304 being located on the base member 1 and the main control coil 302 being located on the first bracket member 2, and also includes the compensation control coil 304 being located on the first bracket member 2 and the main control coil 302 being located on the base member 1.

[0092] In addition, the magnetic field coupling mode between the compensation magnet 303 and the compensation control coil 304 is the same as the magnetic field coupling mode between the main magnet 301 and the main control coil 302 .

[0093] The magnetic poles of the main magnet 301 are arranged along one of the first direction X and the second direction Y, and the magnetic poles of the compensation magnet 303 are arranged along the other of the first direction X and the second direction Y. The arrangement direction of the magnetic poles determines the direction of the magnetic field generated by the magnet, so that the magnet can generate a force in the target direction when interacting with the control coil.

[0094] Exemplarily, the magnetic poles of the main magnet 301 are arranged along the first direction X, and the magnetic poles of the compensation magnet 303 are arranged along the second direction Y. Thus, the driving component 3 can rely on the main magnet 301 to provide the power for the first bracket 2 to move along the first direction X, and rely on the compensation magnet 303 to provide the power for the first bracket 2 to move along the second direction Y. By using the driving component 3, it is possible to provide power compensation for the driving component 3 in the second direction Y, and the number of magnets of the driving component 3 in the second direction Y can be reduced accordingly, which can reduce magnetic field interference on the one hand, and reduce the number of magnets on the other hand, which is conducive to reducing costs and reducing the mass of the actuator.

[0095] In another exemplary embodiment, the magnetic poles of the main magnet 301 are arranged along the second direction Y, and the magnetic poles of the compensation magnet 303 are arranged along the first direction X. Thus, the driving component 3 can rely on the main magnet 301 to provide the power for the first bracket 2 to move along the second direction Y, and rely on the compensation magnet 303 to provide the power for the first bracket 2 to move along the first direction X. By using the driving component 3, power compensation can be provided for the driving component 3 in the first direction X, and the number of magnets of the driving component 3 in the first direction X can be reduced accordingly, which can reduce magnetic field interference on the one hand, and reduce the number of magnets on the other hand, which is conducive to reducing costs and reducing the mass of the actuator.

[0096] like Figure 3As shown, the main magnet 301 and the compensation magnet 303 each include two magnetic poles, namely an N pole and an S pole, wherein the N pole and the S pole of the main magnet 301 are arranged along one of the first direction X and the second direction Y, and the N pole and the S pole of the compensation magnet 303 are arranged along the other direction of the first direction X and the second direction Y.

[0097] Taking the case where the magnetic poles of the main magnet 301 are arranged along the first direction X and the magnetic poles of the compensation magnet 303 are arranged along the second direction Y as an example:

[0098] Taking the center of the main magnet 301 as the origin of the first direction X, the N pole of the main magnet 301 is located on the positive side of the first direction X, and the S pole is located on the negative side of the first direction X, or the S pole of the main magnet 301 is located on the positive side of the first direction X, and the N pole is located on the negative side of the first direction X.

[0099] Taking the center of the compensation magnet 303 as the origin of the second direction Y, the N pole of the compensation magnet 303 is located on the positive direction side of the second direction Y, and the S pole is located on the negative direction side of the second direction Y, or, the S pole of the compensation magnet 303 is located on the positive direction side of the second direction Y, and the N pole is located on the negative direction side of the second direction Y.

[0100] Need to explain, Figure 3 The positions of the N pole and the S pole of the middle magnet are only one example of this embodiment, and the positions of the N pole and the S pole of any magnet can be interchanged, which is not limited in this application.

[0101] In the actuator of this embodiment, the first bracket member 2 can move relative to the base member 1 along the first direction X and the second direction Y respectively under the drive of the driving component 3, which can be suitable for realizing optical image stabilization of the camera module; the driving component 3 relies on the main magnet member 301 and the main control coil 302 respectively arranged on the first bracket member 2 and the base member 1, and the magnetic fields of the two are coupled with each other. When the current of the main control coil 302 changes, its magnetic field changes accordingly, and the main magnet member 301 is acted upon by the Ampere force, thereby driving the first bracket member 2 to move relative to the base member 1.

[0102] Among them, at least one driving component 3 is also provided with a compensating magnet 303 and a compensating control coil 304. The magnetizing direction of the compensating magnet 303 is the same as the magnetizing direction of the main magnet 301 of the driving component 3 in the other direction. The compensating magnet 303 can perform dynamic compensation for the driving component 3 in the other direction. Therefore, when the driving force in this direction is insufficient due to the reduction in the number of magnets, the compensating magnet 303 arranged elsewhere can be used to perform dynamic compensation, thereby avoiding the problem of insufficient driving force caused by the reduction in the number of magnets.

[0103] Combination Figure 1, Figure 2 As shown, in some embodiments, the driving assembly 3 includes a first driving assembly 31 , a second driving assembly 32 and a third driving assembly 33 .

[0104] At least one of the second drive component 32 and the third drive component 33 includes a compensation magnet component 303 and a compensation control coil 304; the first drive component 31 is used to drive the first bracket component 2 to move along the first direction X, and the second drive component 32 and the third drive component 33 are used to drive the first bracket component 2 to move along the second direction Y.

[0105] The actuator of this embodiment uses the first drive component 31 to drive the first bracket component 2 to move along the first direction X, and uses the second drive component 32 and the third drive component 33 to drive the first bracket component 2 to move along the second direction Y, wherein at least one of the second drive component 32 and the third drive component 33 is provided with the aforementioned compensation magnet component 303 and compensation control coil 304, and the second drive component 32 and / or the third drive component 33 can be used to perform power compensation for the first drive component 31, so that only one set of drive components 3 is needed in the first direction X, that is, the number of magnet components is reduced by at least one, which is beneficial to reducing magnetic field interference on the one hand, and on the other hand, it is beneficial to reducing costs and reducing the weight of the actuator.

[0106] Combination Figure 1 , Figure 2 As shown, in some embodiments, the main magnet component 301 and the main control coil 302 of the first driving component 31 are respectively located on one side of the base component 1 or the first bracket component 2 along the first direction X.

[0107] The main magnet component 301 and the main control coil 302 of the second driving component 32 are respectively located on one side of the base component 1 or the first bracket component 2 along the second direction Y; the main magnet component 301 and the main control coil 302 of the third driving component 33 are respectively located on the other side of the base component 1 or the first bracket component 2 along the second direction Y.

[0108] The actuator of this embodiment relies on the second drive component 32 and the third drive component 33 corresponding to the second direction Y to provide power compensation for the first drive component 31 corresponding to the first direction X, thereby realizing a three-sided magnet actuation scheme. Three groups of magnets are arranged on three sides of the actuator respectively, while there is no magnet arrangement on the other side along the first direction X, that is, the opposite side of the first drive member, so that this side has good magnetic field conditions. This side is defined as a weak magnetic side. For example, in a multi-camera module scenario, the actuator of the camera module is oriented with the weak magnetic side toward the adjacent camera module, which is beneficial to reduce the magnetic interference of the actuator of this camera module to the adjacent camera module. Furthermore, each camera module can be oriented with the weak magnetic side toward the adjacent camera module.

[0109] Combination Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the first driving assembly 31 includes a first main magnet 311, and the magnetic poles of the first main magnet 311 are arranged along the first direction X.

[0110] The second driving assembly 32 includes a second main magnet 321 and a first compensation magnet 323 . The magnetic poles of the second main magnet 321 are arranged along the second direction Y, and the magnetic poles of the first compensation magnet 323 are arranged along the first direction X.

[0111] The third driving assembly 33 includes a third main magnet 331 and a second compensation magnet 333 . The magnetic poles of the third main magnet 331 are arranged along the second direction Y, and the magnetic poles of the second compensation magnet 333 are arranged along the first direction X.

[0112] The driving in the second direction Y relies on the second driving assembly 32 and the third driving assembly 33, which can generate a large driving force, and even have a problem of excess driving force. Compared with the second direction Y, the first direction X is only equipped with the first driving assembly 31, and the driving force is slightly insufficient.

[0113] On this basis, in this embodiment, the magnets in the second direction Y with a larger total driving force are split, the magnets in the second driving assembly 32 are split into the second main magnet 321 and the first compensating magnet 323, and the magnets in the third driving assembly 33 are split into the third main magnet 331 and the second compensating magnet 333. The second main magnet 321 and the third main magnet 331 are used to generate a driving force along the second direction Y. Although the driving force of the more complete magnet is slightly reduced, it can still meet the driving demand of the second direction Y. Although the first compensating magnet 323 and the second compensating magnet 333 are in the second driving assembly 32 and the third driving assembly 33, by arranging the magnetic poles of the two along the first direction X, a driving force along the first direction X can also be generated, so that the driving force in the first direction X is provided by the first main magnet 311, the first compensating magnet 323 and the second compensating magnet 333, which makes up for the problem of insufficient driving force of a single magnet.

[0114] Combination Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the second main magnet component 321 and the first compensation magnet component 323 are arranged at intervals along the first direction X. The second main magnet component 321 and the first compensation magnet component 323 are arranged along the first direction X, which conforms to the arrangement rule of the second drive component 32, does not need to adjust the assembly position and space of the second drive component 32, does not change the structure around the second drive component 32, and especially does not need to change the first bracket component 2, thereby improving the applicability of the actuator of this embodiment.

[0115] Combination Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the third main magnet component 331 and the second compensation magnet component 333 are arranged at intervals along the first direction X. The third main magnet component 331 and the second compensation magnet component 333 are arranged along the first direction X, which conforms to the arrangement rule of the third drive assembly 33, does not need to adjust the assembly position and space of the third drive assembly 33, does not change the structure around the third drive assembly 33, and especially does not need to change the first bracket component 2, thereby improving the applicability of the actuator of this embodiment.

[0116] In some possible implementations, the second main magnet 321 and the third main magnet 331 are respectively attached to two opposite inner walls of the first bracket 2, and the first compensation magnet 323 and the second compensation magnet 333 are attached to the inner wall of the first bracket 2 using the same process. The first bracket 2 serves as a supporting structure for the above-mentioned magnets.

[0117] Combination Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the first compensation magnet 323 is located on the side of the second main magnet 321 close to the first main magnet 311; the first compensation magnet 323 and the first main magnet 311 are close to each other, and the magnetic poles of the two are arranged in the same direction, so that the magnetic field directions of the two are consistent, and the interference between the magnetic fields is small.

[0118] Combination Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the second compensating magnet 333 is located on a side of the third main magnet 331 close to the first main magnet 311. The second compensating magnet 333 and the first main magnet 311 are close to each other, and the magnetic poles of the two are arranged in the same direction, so that the magnetic fields of the two are in the same direction, and the interference between the magnetic fields is small.

[0119] Combination Figure 2 and Figure 3 As shown, in some embodiments, the first drive component 31 also includes a first main control coil 312 , the second drive component 32 also includes a second main control coil 322 and a first compensation control coil 324 , and the third drive component 33 also includes a third main control coil 332 and a second compensation control coil 334 .

[0120] The first main magnet component 311 is located at one side of the first bracket component 2 along the first direction X, and the first main control coil 312 is located at one side of the base component 1 along the first direction X.

[0121] The second main magnet component 321 and the first compensation magnet component 323 are located on one side of the first bracket component 2 along the second direction Y, and the second main control coil 322 and the first compensation control coil 324 are located on one side of the base component 1 along the second direction Y; the third main magnet component 331 and the second compensation magnet component 333 are located on the other side of the first bracket component 2 along the second direction Y, and the third main control coil 332 and the second compensation control coil 334 are located on the other side of the base component 1 along the second direction Y.

[0122] When the first bracket member 2 needs to move along the first direction X, the first main control coil 312, the first compensation control coil 324 and the second compensation control coil 334 are energized, the first main control coil 312 interacts with the first main magnet member 311, the first compensation control coil 324 interacts with the first compensation magnet member 323, and the second compensation control coil 334 interacts with the second compensation magnet member 333. Since the positions of the first main control coil 312, the first compensation control coil 324 and the second compensation control coil 334 are fixed on the base member 1, the first main magnet member 311, the first compensation magnet member 323 and the second compensation magnet member 333 are subjected to a reaction force, driving the first bracket member 2 to move along the first direction X. The moving direction can be the positive direction of the first direction X or the negative direction of the first direction X, and can be controlled by changing the current direction and / or magnitude of the above three control coils.

[0123] When the first bracket member 2 needs to move along the second direction Y, the second main control coil 322 and the third main control coil 332 are energized, the second main control coil 322 interacts with the second main magnetic member 321, and the third main control coil 332 interacts with the third main magnetic member 331. Since the positions of the second main control coil 322 and the third main control coil 332 are fixed on the base member 1, the second main magnetic member 321 and the third main magnetic member 331 are subjected to a reaction force, driving the first bracket member 2 to move along the second direction Y. The moving direction can be the positive direction of the second direction Y or the negative direction of the second direction Y, and can be controlled by changing the current direction and / or magnitude of the above two control coils.

[0124] Combination Figure 3 As shown, in some embodiments, the orthographic projection of the first compensation control coil 324 along the second direction Y and the orthographic projection of the second compensation control coil 334 along the second direction Y are at least partially staggered; or, the orthographic projection of the first compensation magnet 323 along the second direction Y and the orthographic projection of the second compensation magnet 333 along the second direction Y are at least partially staggered.

[0125] In this embodiment, the first compensation control coil 324 and the second compensation control coil 334 are arranged alternately, or the first compensation magnet 323 and the second compensation magnet 333 are arranged alternately, so as to ensure that the first bracket 2 always has a magnet to provide driving force compensation during its movement along the first direction X. The driving force of the first bracket 2 is maintained at a stable level, and there will be no problem of a significant reduction in driving force due to a large moving distance.

[0126] Combination Figure 3 As shown, in some embodiments, the size of the first compensation control coil 324 and the second compensation control coil 334 along the second direction Y is greater than the size of the second main control coil 322 or the third main control coil 332 along the second direction Y, so that during the movement of the first bracket 2 along the second direction Y, the first compensation magnet 323 is always within the magnetic field range of the first compensation control coil 324, and the second compensation magnet 333 is always within the magnetic field range of the second compensation control coil 334, thereby ensuring the drive compensation capability of the second drive component 32 and the third drive component 33 in the first direction X.

[0127] Combination Figure 4 and Figure 5 As shown, in some embodiments, the actuator also includes a second bracket member 4, which is located on the inner side of the first bracket member 2. The second bracket member 4 is provided with a bracket coil 41, and the bracket coil 41 can be coupled with the magnetic field of at least one of the main magnetic member 301, the main control coil 302, the compensation magnetic member 303 and the compensation control coil 304 to drive the second bracket member 4 to move relative to the first bracket member 2 along a third direction Z, and the third direction Z is perpendicular to the plane where the first direction X and the second direction Y are located.

[0128] By using the second bracket member 4 and the bracket coil 41 thereon, the second bracket member 4 can use the bracket coil 41 to perform magnetic field coupling with at least one of the main magnet member 301, the main control coil 302, the compensation magnet member 303 and the compensation control coil 304 of the driving component 3, thereby generating a reverse thrust force to drive the second bracket member 4 to move relative to the first bracket member 2 along the third direction Z. The axis of the bracket coil 41 is the same as the third direction Z.

[0129] Thus, the actuator of this embodiment can realize driving in the first direction X, the second direction Y and the third direction Z, wherein the movement in the first direction X and the second direction Y can realize the anti-shake function of the camera, and the movement in the third direction Z can realize the zoom function of the camera.

The second bracket member 4 is designed as a rotating body structure, the axis of the rotating body structure is the same as the third direction Z, and the bracket coil 41 is wound around the outer peripheral surface of the rotating body structure.

[0131] The first bracket component 2 is a square structure with a circular cavity in the middle for accommodating the second bracket component 4 and serving as an optical path for the photosensitive component in the camera module.

[0132] For example, when the second bracket component 4 needs to move along the third direction Z, the bracket coil 41 is energized, and the bracket coil 41 interacts with the first main magnet component 311, the second main magnet component 321, and the third main magnet component 331, and the generated reaction force drives the second bracket component 4 to move along the third direction Z. The moving direction can be the positive direction of the third direction Z, or the negative direction of the third direction Z, and can be controlled by changing the current direction and / or magnitude of the bracket coil 41.

[0134] The first elastic member 5 is a thread-like elastic member, and is arranged in an array between the base member 1 and the first bracket member 2. For example, there are four first elastic members 5, which are arranged in a rectangular shape at the four corners of the base member 1 to elastically support the first bracket member 2 above the base member 1.

[0135] Combination Figure 4 and Figure 5 As shown, in some embodiments, the actuator also includes at least one second elastic member 6, at least one second elastic member 6 is connected between the second bracket member 4 and the first bracket member 2, and at least one second elastic member 6 is used to movably support the second bracket member 4 on the inner side of the first bracket member 2.

[0136] The second elastic member 6 is a sheet-shaped elastic member, and is symmetrically arranged at the upper and lower ends of the first bracket member 2 and the second bracket member 4. For example, the second elastic member 6 includes an upper elastic sheet 61 and a lower elastic sheet 62, the upper elastic sheet 61 is located at the upper ends of the first bracket member 2 and the second bracket member 4, and the lower elastic sheet 62 is located at the lower ends of the first bracket member 2 and the second bracket member 4, and the upper elastic sheet 61 and the lower elastic sheet 62 work together to elastically connect the second bracket member 4 and the first bracket member 2.

[0137] On the other hand, combined Figure 4 and Figure 5As shown, this embodiment provides a camera module, which includes: an optical lens 7; a photosensitive component, the photosensitive component includes a circuit board and a photosensitive element, the photosensitive element is electrically connected to the circuit board, and the optical lens 7 is located on the light-sensitive path of the photosensitive element; and the actuator of the present application, wherein the optical lens 7 is connected to the first bracket member 2, and the photosensitive component is connected to the base member 1.

[0148] In the camera module provided in this embodiment, during the shooting process, the imaging light of the object enters the optical lens and then reaches the image sensor. The photons in the imaging light hit the image sensor to generate movable charges. This is the internal photoelectric effect, and the movable charges gather to form an electrical signal.

[0149] The electrical signal is transmitted to the main board through a flexible circuit board or the like. The main board is provided with an analog-to-digital converter (A / D converter) and a digital signal processor (DSP). The A / D converter converts the electrical signal into a digital signal, which is processed by the DSP and finally transmitted to the screen of the electronic device to display the image, thus realizing the shooting of the object.
