Abstract
Description
Technical Field
[0001] This application relates to the field of electronic technology, and in particular to a camera assembly, camera module and electronic device. Background Technology
[0002] With the development of portable electronic devices such as smartphones and tablets, electronic devices have become indispensable tools in people's daily lives, enabling them to perform social and entertainment functions. The camera function of electronic devices has become an increasingly demanded feature. However, during the shooting process, problems arise such as blurry and unclear images due to camera shake or incorrect focus. Therefore, electronic devices incorporate camera components that drive the camera module's movement. By driving the relative movement between the lens and image sensor of the camera module, focusing and optical image stabilization are achieved. However, in related technologies, the stability of the relative movement between the lens and image sensor is relatively poor. Summary of the Invention

[0035] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.
[0036] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of a camera module provided in an embodiment of this application. Figure 2 for Figure 1 The diagram shows an exploded view of a camera module. This application provides a camera module 10, which can be used to realize functions such as taking photos, recording videos, facial recognition unlocking, or QR code payment on electronic devices. Furthermore, it should be noted that the camera module 10 can be a front-facing camera or a rear-facing camera; this embodiment does not limit this. The structure of the camera module 10 is described in detail below with reference to the accompanying drawings. The camera module 10 may include a camera assembly 100, an image sensor assembly 200, and a lens 300.
[0037] The lens 300 can be made of materials such as glass or plastic. The lens 300 may contain multiple layers of lenses. The lens 300 can collect external light, change the propagation path of the light, and focus the light. For example... Figure 2 As shown, the camera module 10 may further include a filter assembly 400, which is positioned between the lens 300 and the image sensor assembly 200 along the optical axis of the lens 300. The filter assembly 400 may include one or more filters 410 and a filter holder 420 supporting the filters 410. The multiple filters 410 mutually correct and filter light, so that when light passes through the lens 300, the multiple filters 410 filter stray light (e.g., infrared light) layer by layer, thereby improving the imaging effect of the camera module 10. For example, the filter 410 may be blue glass or other filter structures, and the blue glass may be fixed to the filter holder 420 by means of dispensing or baking.
[0038] Image sensor assembly 200 can be disposed opposite to lens 300 along the optical axis. Image sensor assembly 200 may include image sensor 210 and image sensor circuit board 220. Lens 300, image sensor 210 and image sensor circuit board 220 can be stacked along a first direction H1, which can be the thickness direction of camera module 10 or the optical axis direction of lens 300. Lens 300 and image sensor 210 can be parallel to each other. Image sensor 210 may be, but is not limited to, a charge-coupled device (CCD), complementary metal-oxide-semiconductor (CMOS) or other similar image sensors. Image sensor 210 is mainly used to receive light collected from lens 300 and convert the light signal into an electrical signal to meet the imaging requirements of camera module 10. Image sensor circuit board 220 can carry image sensor 210 and is electrically connected to image sensor 210 to provide power and control signals to image sensor 210. Components such as the image sensor 210 can be mounted on the image sensor circuit board 220 through processes such as surface mount technology (SMT), die bonding (D / B), and wire bonding (W / B).
[0039] The camera assembly 100 can be connected to the image sensor 210 and the lens 300 to drive the image sensor 210 to move relative to it. The camera assembly 100 can be used for focusing the camera module 10 or to improve the imaging effect of the camera module 10 caused by user hand shake, so that the imaging effect of the image sensor 210 meets the user's needs. The camera assembly 100 can provide a driving force to drive the image sensor 210 to move.
[0040] Please combine Figure 1 and Figure 2 Please see Figures 3 to 9 , Figure 3 for Figure 1 The diagram shows another view of the camera module's structure. Figure 4 for Figure 3 The diagram shows a cross-sectional view of the camera module along the AA direction. Figure 5 for Figure 3 The diagram shows a cross-sectional view of the camera module along the BB direction. Figure 6 This is a schematic diagram of a structure of an elastic element provided in an embodiment of this application. Figure 7 This is a schematic diagram of a lens holder provided in an embodiment of this application. Figure 8 This is a schematic diagram of a sensor bracket and a second magnetic module provided in an embodiment of this application. Figure 9 This is a cross-sectional view of the lens bracket, elastic element, sensor bracket, and second magnetic module after they are connected, as provided in the embodiments of this application.
[0041] The camera assembly 100 includes a lens bracket 110, a sensor bracket 120, an elastic element 130, a base plate 140, and a drive mechanism 150. The lens bracket 110 is fixedly connected to the base plate 140 and is used to support the lens 300 of the camera module 10.
[0042] The sensor bracket 120 is disposed between the base plate 140 and the lens bracket 110, and the sensor bracket 120 is used to support the image sensor 210 of the camera module 10.
[0043] Drive mechanism 150 is used to drive sensor bracket 120 to move so that image sensor 210 moves relative to lens.
[0044] The elastic element 130 is disposed between the lens bracket 110 and the sensor bracket 120. The elastic element 130 includes a first connecting part 131, a second connecting part 132 and an elastic part 133. The first connecting part 131 is connected to the lens bracket 110, the second connecting part 132 is connected to the sensor bracket 120, and the elastic part 133 is used to provide elastic force when the sensor bracket 120 moves.
[0045] The camera assembly 100 provided in this application embodiment fixes the larger and heavier lens 300 to the lens bracket 110. The lens 300 is fixed relative to the entire camera module 10. The focusing and / or image stabilization functions are achieved by driving the movement of the lighter image sensor through the drive mechanism 150. This reduces the driving force and thus reduces the power consumption of the camera module 10. In addition, since the movement is driven by the lighter image sensor 210, the reliability is stronger compared to driving the movement of the heavier lens. In order for the image sensor 210 to be driven by the drive mechanism 150, the image sensor 210 is mounted on a movable sensor bracket 120. The sensor bracket 120 is elastically connected to the lens bracket 110 through an elastic member 130, so that the sensor bracket 120 is suspended inside the camera module 10. There is a gap between the sensor bracket 120 and the base plate 140. The elastic member 130 not only allows the lens bracket 110 and the sensor bracket 120 to be movably connected and the sensor bracket 120 to be suspended, but also allows the elastic part 133 of the elastic member 130 to deform when the drive mechanism 150 drives the sensor bracket 120 to move, providing elastic force to ensure the stability of the movement of the sensor bracket 120. In addition, when the drive mechanism 150 stops driving the sensor bracket 120, it provides elastic restoring force to the sensor bracket 120, so that the sensor bracket 120 can quickly return to its original position.
[0046] The lens bracket 110 may include a lens mounting portion 111 and a cover portion 112 disposed around the lens mounting portion 111. The cover portion 112 is fixedly connected to the base plate 140 and covers the sensor bracket 120. The first connecting portion 131 is fixedly connected to the cover portion 112. The lens bracket 110 can serve as a bracket for mounting the lens 300 and as the housing of the camera module 10. The lens mounting portion 111 may be provided with a receiving hole 1111 for accommodating the lens 300, depending on the structure of the lens 300. The lens 300 can be fixedly disposed within the receiving hole 1111. The cover portion 112 covers the sensor bracket 120, and the first connecting portion 131 of the elastic member 130 can be connected to the cover portion 112.
[0047] The sensor bracket 120 may include a housing 121 and a support plate 122. The support plate 122 supports the image sensor 210. The housing 121 covers the support plate 122 and has a light-passing port 1211. The light-passing port 1211 faces the image sensor 210 and the lens 300, so that external light collected by the lens 300 can enter the image sensor 210 through the light-passing port 1211, allowing the image sensor 210 to collect external light and form an image. The second connecting portion 132 of the elastic member 130 may be connected to the housing 121 on the side of the housing 121 facing the cover portion 112 of the lens bracket 110.
[0048] The second connecting part 132 can be directly fixedly connected to the housing 121, or it can be fixedly connected to the housing 121 through the driving mechanism 150 fixedly connected to the housing 121. For example, the driving mechanism 150 may include a first magnetic module 151 and a second magnetic module 152. The second magnetic module 152 and the first magnetic module 151 can generate a magnetic force, which can cause the sensor bracket 120 to move. The first magnetic module 151 is disposed on the lens bracket 110. For example, the first magnetic module 151 can be disposed on the lens mounting part 111 of the lens bracket 110. The second magnetic module 152 can be disposed on the outside of the housing 121 of the sensor bracket 120. For example, the second magnetic module 152 is disposed on the side 1212 of the housing 121 facing the cover part 112 of the lens bracket 110. In this case, the second connecting part 132 can be fixedly connected to the second magnetic module 152 protruding from the housing 121. The protruding second magnetic module 152 can make the elastic part 133 spaced apart from the surface of the housing 121, providing deformation space for the elastic part 133 and avoiding contact between the elastic part 133 and the housing 121 when the elastic part 133 deforms, thus affecting the movement of the housing 121. It is understandable that the structure of the elastic element 130, as well as the structure of the lens bracket 110 and the sensor bracket 120, can be improved according to actual needs to meet the requirements of the elastic element 130 as a connecting structure so that the sensor bracket 120 can be suspended in the camera module 10 and to provide elasticity when the sensor bracket 120 moves.
[0049] The elastic part 133 of the elastic element 130 can be disposed between the first connecting part 131 and the second connecting part 132 and connected to the first connecting part 131 and the second connecting part 132 respectively. When the second connecting part 132 moves with the sensor bracket 120, the deformable elastic part 133 is compressed or stretched. When the elastic part 133 is compressed or stretched, an elastic force can be generated. The elastic force can act on the sensor bracket 120 and play an auxiliary role in the movement of the sensor bracket 120.
[0050] To reduce the space occupied by the elastic element 130 within the camera module 10, the first connecting portion 131, the second connecting portion 132, and the elastic portion 133 can be arranged flush, meaning that when the elastic portion 133 is not compressed or stretched, the first connecting portion 131, the second connecting portion 132, and the elastic portion 133 can be located on the same plane. Furthermore, to reduce the lateral volume of the camera module 10, the elastic element 130 can be vertically arranged within the camera module 10, providing vertical space within the camera module 10 for the deformation of the elastic portion 133. In other words, the first... The connecting portion 131, the elastic portion 133, and the second connecting portion 132 are arranged flush along a direction parallel to the optical axis of the lens 300. Compared to the structure in which the first connecting portion 131, the elastic portion 133, and the second connecting portion 132 are arranged along a direction perpendicular to the optical axis of the lens 300, the distance between the side 1212 of the housing 121 of the sensor bracket 120 and the cover portion 112 of the lens bracket 110 can be reduced, thereby reducing the size of the cover portion 112 of the lens bracket 110 and satisfying the miniaturization design of the camera module 10.
[0051] To ensure uniform force distribution during deformation, the elastic portion 133 is arranged around the second connecting portion 132, and the first connecting portion 131 is arranged around the elastic portion 133. That is, the elastic portion 133 is disposed around the second connecting portion 132. For example, the elastic portion 133 can be a bent structure 1331 extending outwards from the edge of the second connecting portion 132. The first end of the bent structure is connected to the edge of the second connecting portion 132, and the other end is connected to the periphery of the first connecting portion 131. The first connecting portion 131 is disposed around the elastic portion 133 and the second connecting portion 132. It is understood that the first connecting portion 131, the second connecting portion 132, and the elastic portion 133 can be integrally formed, or they can be separately formed and connected by other connecting structures to assemble the elastic element 130. The elastic part 133 may include one or more bending structures 1331. When subjected to external force, the bending structure 1331 can be compressed or stretched to deform and provide elasticity. It is understood that the elastic part 133 shown in the figure is merely exemplary, and it can also be a flexible structure such as a spring or a wire. In addition, the shape and movable direction of the elastic part can be set according to actual needs. For example, if only the sensor bracket 120 needs to move up and down relative to the lens bracket 110 along the optical axis of the lens 300, then the structure of the elastic part 133 only needs to be designed to provide elasticity for the up and down movement of the lens bracket 110 and the sensor bracket 120. If the sensor bracket 120 also needs to move relative to the lens bracket 110 in a plane perpendicular to the optical axis of the lens 300, then the structure of the elastic part 133 also needs to be designed to provide elasticity for the forward, backward, left and right movement of the lens bracket 110 and the sensor bracket 120 in a plane perpendicular to the optical axis of the lens 300. That is, the compressible and stretchable directions of the elastic part 133 can be designed according to actual needs.
[0052] The elastic element provided in this application embodiment not only enables a movable connection between the sensor bracket and the lens bracket, allowing the sensor bracket to be suspended within the camera assembly, but also provides elastic force to limit the movement of the sensor bracket during its movement, preventing the sensor bracket from moving beyond expectations due to excessive driving force. Furthermore, it allows the sensor bracket to return to its initial position after the magnetic force between the first magnetic modules disappears, thus resetting the sensor bracket and ensuring the stability of the camera module's operation.
[0053] The principle of the movement of the sensor bracket 120 relative to the lens bracket 110 is illustrated by taking the drive mechanism 150, which includes a first magnetic module 151 and a second magnetic module 152. Since the lens bracket 110 is fixedly connected to the base plate 140, and the sensor bracket 120 is connected to the lens bracket through a movable elastic element 130, the sensor bracket 120 can move relative to the lens bracket 110 and the base plate 140 under the action of the magnetic force between the first magnetic module 151 and the second magnetic module 152. This allows the image sensor 210 mounted on the sensor bracket 120 to move relative to the lens 300 mounted on the lens bracket 110, thereby enabling the camera module 10 to perform focusing or image stabilization functions.
[0054] For example, the magnetic force between the first magnetic module 151 and the second magnetic module 152 can drive the sensor bracket 120 to move up and down along the first direction H1, thereby causing the image sensor 210 to move up and down along the first direction H1. The first direction H1 is the optical axis direction of the lens 300, which can make the image sensor 210 move closer to or further away from the lens 300 along the optical axis direction of the lens 300 to achieve the focusing function of the lens.
[0055] For example, the magnetic force between the first magnetic module 151 and the second magnetic module 152 can drive the sensor bracket to move back and forth and left and right in a plane perpendicular to the first direction H1, or rotate about the first direction H1 as a rotation axis, so that the image sensor 210 can compensate for the lens 300 according to the shaking direction and displacement of the lens 300, thereby improving the imaging effect of the camera module 10 caused by shaking during user use. The shaking direction and displacement of the lens 300 can be set inside the camera module 10 or located in the same electronic device as the camera module 10. Sensors such as gyroscopes or accelerometers detect movement, such as lens 300 shaking, which generates a shaking signal. This shaking signal is detected by the gyroscope or accelerometer and transmitted to the processing chip of the electronic device and / or camera module 10. The processing chip of the electronic device and / or camera module 10 can calculate the amount of displacement that the camera assembly 100 needs to compensate for, so that the camera assembly 100 can compensate for the lens 300 according to the shaking direction and displacement of the lens 300, thereby improving the imaging effect of the camera module 10 caused by shaking during user use.
[0056] The first magnetic module 151 may include a magnetic component, such as a magnet, which is disposed on the inner side of the lens bracket 110 facing the lens 300. The magnetic component may be arranged around the lens and can be a ring magnet or a segmented magnet arranged around the lens. The second magnetic module 152 may include an electromagnetic component that generates an electromagnetic field when energized, such as an electromagnetic coil. When energized, it generates a magnetic field, which in turn generates a magnetic force. Under the action of the magnetic force of the magnetic component and the electromagnetic component, since the magnetic component and the lens bracket 110 are fixed, the sensor bracket 120 connected to the lens bracket 110 via the elastic member 130 is movable. Under the action of the magnetic force, the electromagnetic component drives the sensor bracket 120 to move in a preset direction to achieve the focusing or image stabilization function of the camera module 10. The electromagnetic component may include one or more electromagnetic coils. Multiple electromagnetic coils may be two or more electromagnetic coils. When the electromagnetic component includes multiple electromagnetic coils, electromagnetic coils located in different positions can be set at different locations on the sensor bracket 120 according to the structure of the sensor bracket 120, which can improve the stability of the drive.
[0057] For example, the electromagnetic component may include a first electromagnetic coil 1521, a second electromagnetic coil 1522, and a third electromagnetic coil 1523. The first electromagnetic coil 1521 and the third electromagnetic coil 1523 are arranged opposite to each other, and the second electromagnetic coil 1522 is arranged between the first electromagnetic coil 1521 and the third electromagnetic coil 1523. The line connecting the positions of the first electromagnetic coil 1521, the second electromagnetic coil 1522, and the third electromagnetic coil 1523 can form a triangular structure. The magnetic component can be arranged above the triangular structure. Since the three electromagnetic coils are located in different directions and generate magnetic fields, the composite magnetic field generated by the three electromagnetic coils produces a relatively stable composite magnetic field force on the magnetic component. At this time, the second connecting portion 132 of the elastic element 130 can be fixedly connected to the first electromagnetic coil 1521, the second electromagnetic coil 1522, and the third electromagnetic coil 1523 respectively. Correspondingly, the elastic portion 133 and the first connecting portion 131 are also provided, that is, the elastic portion 133 is arranged around the second connecting portion 132, and the first connecting portion 131 is arranged around the elastic portion 133 and the second connecting portion 132. It can be understood that the position and number of electromagnetic coils are merely exemplary, and the position and number of electromagnetic coils can be set according to actual needs. The structure of the elastic element 130 is designed based on the position and number of electromagnetic coils.
[0058] The camera assembly provided in this application fixes the large and heavy lens to the lens bracket, so that the lens is fixed relative to the entire camera module. Focusing and / or image stabilization functions are achieved by driving the movement of the relatively light image sensor. This reduces the driving force and thus the power consumption of the camera module. In addition, since the movement is driven by the relatively light image sensor, the reliability is stronger than that of driving the movement of the relatively heavy lens.
[0059] In some embodiments, the positions of the magnetic components and the electromagnetic components can be changed. For example, the first magnetic module set on the lens bracket may include an electromagnetic component, and the second magnetic module set on the sensor bracket may include a magnetic component. The electromagnetic component can generate an electromagnetic field when energized. That is to say, the positions of the magnetic components and the electromagnetic components can be set according to the convenience of the electromagnetic component wiring and the functions to be achieved.
[0060] It should be noted that the first magnetic module 151 and the second magnetic module 152 can be designed to achieve focusing and / or image stabilization functions according to actual needs. When the first magnetic module 151 and the second magnetic module 152 are only designed to achieve focusing, the image stabilization function can be achieved by driving the image sensor 210 relative to the lens 300 through other driving components. When the first magnetic module 151 and the second magnetic module are only designed to achieve image stabilization, the focusing function can be achieved by driving the image sensor 210 relative to the lens 300 through other driving components. When the first magnetic module 151 and the second magnetic module 152 are designed to achieve both focusing and image stabilization functions, then no other driving components are needed to achieve both focusing and image stabilization functions.
[0061] The focusing function and the image stabilization function are implemented by the first magnetic module 151 and the second magnetic module 152, and the driving component is used to drive the image sensor 210 to translate in a plane perpendicular to the optical axis of the lens 300 or to rotate about the optical axis of the lens 300.
[0062] For example, please combine Figure 2 Continue reading Figure 10 and Figure 11 , Figure 10 An exploded structural diagram of the sensor bracket and drive assembly provided in the embodiments of this application. Figure 11 for Figure 10The schematic diagram of a partial structure shown illustrates that the sensor bracket 120 includes a housing 121 and a support plate 122. The housing 121 covers the support plate 122. The second magnetic module 152 is disposed on the housing 121. The support plate 122 is used to support the image sensor 210. The camera assembly 100 also includes a drive assembly 170, which is used to drive the image sensor 210 to translate in a plane perpendicular to the lens optical axis or rotate about the lens optical axis to achieve image stabilization compensation of the camera module. The support plate 122 may include spaced... The device includes a fixed component 1221 and a movable component 1222. The fixed component 1221 is connected to the housing 121, and the movable component 1222 is used to support the image sensor 210. The drive assembly 170 includes a moving component 171 and a plurality of deformable components 172. The moving component 171 is connected to the movable component 1222. One end of each deformable component 172 is connected to the fixed component 1221, and the other end is connected to the moving component 171. The plurality of deformable components 172 can deform in the energized state to drive the moving component 171, the movable component 1222, and the image sensor 210 to move.
[0063] The carrier plate 122 can serve as the circuit board of the image sensor 210 and carry the image sensor 210, that is, the carrier plate 122 is the image sensor circuit board 220. The carrier plate 122 can also serve as the carrier of the circuit board of the image sensor 210, that is, the image sensor circuit board 220 and the image sensor 210 are disposed on the carrier plate 122.
[0064] The fixed member 1221 can be sleeved on the outer periphery of the movable member 1222, and a gap can be formed between the fixed member 1221 and the movable member 1222 so that the movable member 1222 can move relative to the fixed member 1221. The image sensor 210 (or image sensor assembly 200) can be directly or indirectly connected to the movable member 1222 and move synchronously with the movement of the movable member 1222.
[0065] The support plate 122 can be disposed opposite to the drive assembly 170 in the optical axis direction of the lens 300. The drive assembly 170 can be disposed on one side of the support plate 122. The drive assembly 170 can be disposed on the side of the support plate 122 away from the base plate 140, so that the drive assembly 170 can drive the support plate 122 to move above the support plate 122. Of course, the drive assembly 170 can also be disposed on the lower side of the support plate 122, for example, on the lower side of the support plate 122 and the image sensor assembly 200, so that the drive assembly 170 can drive the support plate 122 to move below the support plate 122 and the image sensor assembly 200. The embodiments of this application do not specifically limit the placement of the drive assembly 170.
[0066] The drive assembly 170 may include a movable member 171 and multiple deformable members 172. The movable member 171 may be directly or indirectly connected to the movable member 1222, thereby forming a whole with the movable member 171, the movable member 1222, and the image sensor 210 (or image sensor assembly 200) disposed on the movable member 1222. One end of each deformable member 172 may be directly or indirectly connected to the fixed member 1221, and the other end may be directly or indirectly connected to the movable member 171. When energized, the multiple deformable members 172 may deform to drive the overall movement of the movable member 171, the movable member 1222, and the image sensor 210, so that the movable member 171, the movable member 1222, and the image sensor 210 can move synchronously. For example, multiple deformable components 172 can deform when energized to drive the moving component 171, the movable component 1222, and the image sensor 210 to move along the optical axis perpendicular to the lens 300 or rotate around the optical axis of the lens 300. The image sensor 210 can rotate in the X-axis, Y-axis, or XOY plane under the action of the camera assembly 100.
[0067] It is understandable that the optical axis direction of lens 300 can be a first direction H1, which can be a vertical direction, such as the Z-axis direction in a coordinate system. The optical axis direction perpendicular to lens 300 can be a second direction, which can be any horizontal direction in a horizontal plane, such as the X-axis or Y-axis direction in a coordinate system. The optical axis direction surrounding lens 300 can be any direction in a plane perpendicular to the optical axis of lens 300, such as any direction in the XOY plane in a coordinate system.
[0068] It is understood that the multiple deformable elements 172 are made of shape memory alloys (SMA). When energized, the shape memory alloy can be heated and deformed, causing the length of the multiple deformable elements 172 to change. When energized or when different currents are transmitted to the multiple deformable elements 172, the length of the multiple deformable elements 172 can change. Since one end of each deformable element 172 is fixed with the fixing member 1221 of the support plate 122 and the other end moves with the moving member 171, the multiple deformable elements 172 with changed lengths can drive the moving member 171 to move. The moving member 171 can also drive the moving member 1222 and the image sensor 210 that are directly or indirectly connected to it to move.
[0069] In the camera assembly 100 of this application embodiment, the driving assembly 170 includes a movable member 171 and a plurality of deformable members 172. The movable member 171 is connected to the movable member 1222 of the support plate 122. One end of each deformable member 172 is connected to the movable member 171, and the other end is connected to the fixed member 1221 of the support plate 122. Thus, when the plurality of deformable members 172 deform, they can drive the movable member 171 to move. The movable member 171 can drive the movable member 1222 and the image sensor 210 disposed on the movable member 1222 to move. Thus, the camera assembly 100 can realize the image sensor 210's image stabilization function. At the same time, the two ends of the deformable member 172 are respectively connected to the fixed member 1221 and the movable member 171. The deformable member 172 does not need to occupy the space of the movable member 1222, and the deformable member 172 will not affect the distribution of circuits on the movable member 1222, thereby reducing the impact of the deformable member 172 on the circuits on the movable member 1222. Furthermore, the moving part 171 and the support plate 122 are independent of each other. In the production and assembly process, the moving part 171 and the support plate 122 can be produced modularly to improve their adaptability. It should be noted that the moving part 171 and the support plate 122 can also be produced together using the same production process. The embodiments of this application do not limit the specific preparation process of the moving part 171 and the support plate 122.
[0070] The drive assembly 170 may further include multiple movable ends 173 and multiple fixed ends 174. The multiple movable ends 173 may be disposed on the moving member 171, and the multiple fixed ends 174 may be disposed on the fixed member 1221. One end of a deformable member 172 may be directly or indirectly connected to a movable end 173, and the other end may be directly or indirectly connected to a fixed end 174. When the length of the deformable member 172 changes in the energized state, the movable end 173 connected to the deformable member 172 may move along with the moving member 171 as the length of the deformable member 172 changes, while the fixed end 174 connected to the deformable member 172 remains fixed along with the fixed member 1221 and does not move.
[0071] It is understood that one or more movable ends 173 can be spaced apart and connected to the movable member 171, and two or more of the multiple movable ends 173 can also be arranged adjacently (or connected to each other) without spacing. Similarly, one or more fixed ends 174 can be spaced apart and connected to the fixed member 1221 (e.g., spaced apart on the front of the fixed member 1221), and two or more of the multiple fixed ends 174 can also be arranged adjacently (or connected to each other) without spacing. This application embodiment does not specify the specific arrangement of the multiple movable ends 173 and the multiple fixed ends 174.
[0072] For example, such as Figure 11As shown, the driving component 170 may include two movable ends 173 spaced apart and two fixed ends 174 spaced apart. For example, the two movable ends 173 and the two fixed ends 174 may form a quadrilateral structure, with the two movable ends 173 located on one diagonal of the quadrilateral structure and the two fixed ends 174 located on the other diagonal, forming the four vertices of the quadrilateral structure. In this case, the camera component 100 may also be provided with four deformable elements 172, which may correspond to the four sides of the quadrilateral structure. Based on the easily deformable nature of quadrilateral structures, when a deformable element 172 deforms, it is more easily affected by the movable ends 173 and fixed ends 174 located at the vertices, causing the quadrilateral structure to change and thus more easily driving the movable element 1222 and the image sensor 210 mounted on the movable element 1222 to move.
[0073] It is understood that one or more movable ends 173 can be integrally formed on the movable part 171, and one or more fixed ends 174 can also be integrally formed on the fixed part 1221. When the deformable part 172 is connected to the movable end 173 or the fixed end 174 by means of winding, snap-fitting, welding, etc., compared with the solution of directly connecting the deformable part 172 to the fixed part 1221, in the process of connecting the deformable part 172 with the movable end 173 and the fixed end 174, it is not easy to damage the fixed part 1221, and it is not easy to damage the circuit wiring on the fixed part 1221.
[0074] It is understood that the number of movable ends 173 and fixed ends 174 can be equal to half the number of deformable parts 172, so that one movable end 173 can connect to the ends of two deformable parts 172, and one fixed end 174 can also connect to the ends of two deformable parts 172. Thus, the drive assembly 170 of this application embodiment can be provided with fewer movable ends 173 and fixed ends 174.
[0075] It is understood that the camera assembly 100, camera module 10, or electronic device may also include a drive control chip, which may be disposed on the fixing member 1221 of the carrier plate 122 and form a drive circuit that causes the deformable member 172 to deform. Alternatively, a drive circuit may be separately disposed on the fixing member 1221, and the drive control chip may be electrically connected to the drive circuit on the fixing member 1221 through the aforementioned drive adapter plate 700. At least one of the plurality of movable ends 173 and the plurality of fixed ends 174 may be a conductive device, so that the drive circuit may be electrically connected to the deformable member 172 through the plurality of movable ends 173, or through the plurality of fixed ends 174, or simultaneously through the plurality of movable ends 173 and the plurality of fixed ends 174, thereby the drive control chip may provide drive current to the deformable member 172.
[0076] It is understandable that the movable end 173 and the fixed end 174 can have a certain height so that the movable end 173 and the fixed end 174 can isolate the support plate 122 from the moving part 171 and the deformable part 172. Thus, when multiple deformable parts 172 deform, they are less likely to come into contact with the support plate 122, which can avoid the deformation interference of the support plate 122 on the deformable parts 172; at the same time, it can also prevent the circuit on the support plate 122 from coming into contact with the deformable parts 172 and short-circuiting.
[0077] The drive assembly 170 can be provided with multiple movable ends 173 and fixed ends 174. The deformable part 172 is connected to the fixed part 1221 of the carrier plate 122 and the moving part 171 of the drive assembly 170 through the movable end 173 and the fixed end 174. The connection process of the deformable part 172 is simpler and will not affect the circuit wiring on the fixed part 1221. At the same time, the movable end 173 and the fixed end 174 can be used as conductive devices to power the deformable part 172, which can simplify the power supply circuit layout of the deformable part 172 and realize the miniaturization design of the camera assembly 100.
[0078] Multiple deformable elements 172 can be arranged around the movable element 171 to better control the movement of the movable element 171. Please continue reading. Figure 12 , Figure 12 for Figure 10 The diagram shows the structure of the movable component. The movable component 171 may include a central portion 1711, a first extension 1712, and a second extension 1713. The central portion 1711 may be a rectangular frame structure. The first extension 1712 and the second extension 1713 are located at two opposite corners of the central portion 1711. The central portion 1711 is located above the movable component 1222. The first extension 1712 extends from one corner of the central portion 1711 to above the fixed component 1221, and the second extension 1713 extends from the other corner of the central portion 1711 to above the fixed component 1221. The first extension 1712 and the second extension 1713 may extend in a direction away from each other. Each of the first extension 1712 and the second extension 1713 has a movable end 173.
[0079] Please combine Figures 10 to 12The fixed member 1221 can be a rectangular frame structure, and the movable member 1222 can be located in the hollow area of the fixed member 1221. When the drive assembly 170 includes two movable ends 173 and two fixed ends 174, the two movable ends 173 can be disposed on the first extension 1712 and the second extension 1713 of the movable member 171, and the two fixed ends 174 can be disposed on the two opposite ends of the fixed member 1221. Each movable end 173 is located between the two fixed ends 174, and each fixed end 174 is located between the two movable ends 173. Thus, the two movable ends 173 can be located on the diagonal of the movable member 171, and the two fixed ends 174 can be located on the diagonal of the movable member 171.
[0080] The drive assembly 170 includes four deformable elements 172 located on the four sides of the fixed member 1221. Specifically, each deformable element 172 is positioned relative to one side of the fixed member 1221, with one end connected to a movable end 173 and the other end connected to a fixed end 174. It is understood that the four deformable elements 172 cooperate to move the movable member 171, for example, allowing the movable member 171 to move along a direction perpendicular to the optical axis of the lens 300 or rotate around the optical axis of the lens 300.
[0081] To facilitate understanding of how the image sensor 210 is controlled by the deformable element 172 in this embodiment, an example is given below. Please refer to the following. Figure 10 and Figure 11 The four deformable elements 172 may include a first deformable element 1721, a second deformable element 1722, a third deformable element 1723, and a fourth deformable element 1724.
[0082] When the first deformable element 1721 is energized to shorten and contract, and / or the third deformable element 1723 is energized to lengthen and relax, the first deformable element 1721 and the third deformable element 1723 can drive the moving element 171, the movable element 1222, and the image sensor 210 to translate to the right along the X-axis. When the first deformable element 1721 is energized to lengthen and relax, and / or the third deformable element 1723 is energized to shorten and contract, the first deformable element 1721 and the third deformable element 1723 can drive the moving element 171, the movable element 1222, and the image sensor 210 to translate to the left along the X-axis.
[0083] When the second deformable element 1722 is energized to shorten and contract, and / or the fourth deformable element 1724 is energized to lengthen and relax, the second deformable element 1722 and the fourth deformable element 1724 can drive the moving element 171, the movable element 1222, and the image sensor 210 to translate in the negative direction of the Y-axis. When the second deformable element 1722 is energized to lengthen and relax, and / or the fourth deformable element 1724 is energized to shorten and contract, the second deformable element 1722 and the fourth deformable element 1724 can drive the moving element 171, the movable element 1222, and the image sensor 210 to translate in the positive direction of the Y-axis.
[0084] When the first deformable element 1721 and the third deformable element 1723 are simultaneously energized and shortened, the first deformable element 1721 and the third deformable element 1723 can drive the moving element 171, the movable element 1222, and the image sensor 210 to rotate clockwise in the XOY plane along the diagonal of the moving element 171. When the first deformable element 1721 and the third deformable element 1723 are simultaneously energized and lengthened, the first deformable element 1721 can drive the moving element 171, the movable element 1222, and the image sensor 210 to rotate counterclockwise in the XOY plane along the diagonal of the moving element 171.
[0085] When the second deformable element 1722 and the fourth deformable element 1724 are simultaneously energized and shortened, the second deformable element 1722 and the fourth deformable element 1724 can drive the moving element 171, the movable element 1222, and the image sensor 210 to rotate counterclockwise in the XOY plane along the diagonal of the moving element 171. When the second deformable element 1722 and the fourth deformable element 1724 are simultaneously energized and lengthened, the second deformable element 1722 and the fourth deformable element 1724 can drive the moving element 171, the movable element 1222, and the image sensor 210 to rotate clockwise in the XOY plane along the diagonal of the moving element 171.
[0086] In the camera assembly 100 of this embodiment, the first deformable element 1721, the second deformable element 1722, the third deformable element 1723, and the fourth deformable element 1724 are arranged around the moving element 171. The multiple deformable elements 1722 can symmetrically and uniformly control the movement of the moving element 171, making the movement distance and direction of the moving element 171 more controllable and facilitating the camera assembly 100 to calculate the image sensor 210's anti-shake parameters. Simultaneously, the multiple deformable elements 172 can drive the moving element 171 and the image sensor 210 to achieve translational anti-shake on the X and Y axes, and also achieve rotational anti-shake in the XOY plane. The camera assembly 100's adaptability allows for anti-shake compensation in various shaking scenarios, and the camera module 10 can achieve anti-shake compensation in various shaking scenarios, resulting in superior adaptability.
[0087] It should be noted that the embodiments of this application do not limit the specific manner in which the multiple deformable parts 172 drive the moving parts 171, the movable parts 1222 and the image sensor 210 to move.
[0088] Understandably, the frame structure of the movable member 171 can be adapted to the size of the movable member 1222 of the support plate 122, so that the movable member 171 can carry the movable member 1222. The projections of the first extension 1712 and the second extension 1713 of the movable member 171 onto the support plate 122 can be located on the fixed member 1221 of the support plate 122, so that the quadrilateral structure formed by the two movable ends 173 and the two fixed ends 174 can be adapted to the size of the fixed member 1221, thereby allowing the length of the multiple deformable members 172 to be longer, and the multiple deformable members 172 to drive the movable member 171, the movable member 1222 and the image sensor 210 to have a larger movement stroke.
[0089] In this embodiment, the movable member 171 is provided with a first extension 1712 and a second extension 1713. On the one hand, the first extension 1712 and the second extension 1713 can carry two movable ends 173. On the other hand, the first extension 1712 and the second extension 1713 make the deformable member 172 longer, and the deformable member 172 drives the movable member 171, the movable member 1222 and the image sensor 210 to move a greater distance, so that the image stabilization compensation of the camera assembly 100 to the image sensor 210 can be greater.
[0090] It is understandable that when the magnetic force between the first magnetic module 151 and the second magnetic module 152 is used to achieve the focusing function, the structure of the elastic part 133 of the elastic element 130 can be designed so that the elastic force provided by the elastic part 133 can only move the housing 121 up and down along the optical axis of the lens 300, restricting the housing 121 to translate or rotate in a plane perpendicular to the optical axis of the lens 300, and avoiding the influence of the movement of the housing 121 on the image stabilization function when the drive assembly 170 drives the image sensor to achieve the image stabilization function in a plane perpendicular to the optical axis of the lens 300.
[0091] In some embodiments, the drive assembly 170 may be used only to drive the image sensor 210 to rotate about the optical axis of the lens 300 to achieve image stabilization compensation in the rotational direction of the camera module. The magnetic force generated by the first magnetic module 151 and the second magnetic module 152 is used to drive the image sensor 210 to move along the optical axis of the lens to achieve focusing of the camera module, or to drive the image sensor 210 to translate along a plane perpendicular to the optical axis of the lens 300 to achieve image stabilization compensation in the translational direction of the camera module. At this time, the elastic force provided by the elastic part 133 of the elastic member 130 can allow the housing 121 to move up and down along the optical axis of the lens or to translate in a plane perpendicular to the optical axis of the lens 300.
[0092] It should be noted that the structure of the driving component 170 provided in this application embodiment is merely exemplary, and optical image stabilization can also be achieved by driving the image sensor 210 to move through other driving mechanisms.
[0093] Please continue reading. Figure 13 and Figure 14 , Figure 13 for Figure 10 The diagram shows the structure of the bearing plate and the elastic connector. Figure 14 for Figure 13 The diagram shows an enlarged view of part C of the structure. The sensor bracket 120 may also include one or more elastic connectors 123, which may be disposed between the movable member 1222 and the fixed member 1221, for example, between the outer periphery of the movable member 1222 and the inner periphery of the fixed member 1221. The first end a1 of each elastic connector 123 may be connected to the fixed member 1221 and fixed in place, and the second end a2 may be connected to the movable member 1222 and move with the movable member 1222. The one or more elastic connectors 123 may provide an elastic force opposite to the direction of movement of the movable member 1222 to pull the movement of the movable member 1222. The elastic force provided by the elastic connector 123 and the driving force provided by the driving component 170 may work together on the movable member 1222 so that the movable member 1222 can be stably stopped at a certain position, thereby making the image stabilization control of the movable member 1222 and the image sensor 210 more precise.
[0094] It is understandable that the elastic connector 123 can be made of a material with elastic restoring force.
[0095] For example, the sensor bracket 120 may include four elastic connectors 123, each of which can be a set of trace suspention assemblies (TSAs). Multiple sets of trace suspention assemblies are arranged around the movable member 171. The fixed member 1221 and the movable member 1222 are connected by multiple sets of trace suspention assemblies. The trace suspention assemblies of the elastic connectors 123 are processed using an exposure etching process to ensure the consistency of the elastic coefficient of the trace suspention assemblies. This ensures good consistency of the elastic connectors 123, which can improve the yield of the camera assembly 100.
[0096] To simplify the circuit setup of the camera assembly 100, camera module 10, or electronic device, one or more flexible connectors 123 may be conductive electrical connectors made of a conductive material. That is, one end of the flexible connector 123 is used for electrical connection to the image sensor 210, and the other end is used for electrical connection to external circuitry, thereby electrically connecting the image sensor 210 and the external circuitry. For example, the flexible connector 123 can be electrically connected to the pads (PADs) of the image sensor circuit board 220 via methods such as thermoforming.
[0097] For example, the movable member 1222 may be provided with a first electrical connection terminal that is directly or indirectly electrically connected to the image sensor 210, and the fixed member 1221 may be provided with a second electrical connection terminal that is directly or indirectly electrically connected to an external circuit. The elastic connector 123 may be directly or indirectly electrically connected to the second electrical connection terminal and the first electrical connection terminal respectively, so that the external circuit can be directly or indirectly electrically connected to the image sensor 210 through the second electrical connection terminal, the elastic connector 123, and the first electrical connection terminal. The external circuit can be electrically connected to the second electrical connection terminal through a flexible circuit board. Figure 2 , 4 As shown in Figures 5 and 10, the external circuit can be electrically connected to the image sensor 210 via the flexible circuit board 124 and the second connection terminal, and the first connection terminal of the elastic connector 123. The flexible circuit board 124 can be mounted on the base plate 140. To avoid the image sensor 210 pulling on the base plate 140 when it moves, the flexible circuit board 124 can be provided with a bending structure 1241 at the connection point with the second electrical connection terminal. One end of the bending structure 1241 is connected to the second electrical connection terminal and the other end is connected to the flexible circuit board 124. The bending part in the middle can deform when subjected to external force, thus preventing the flexible circuit board 124 from being directly connected to the fixing member 1221 and restricting the fixing member 1221 from moving up and down in the optical axis direction of the lens 300. The design of this bending structure 1241 can reduce the pulling force on the flexible circuit board 124 when the fixing member 1221 moves, thereby improving the stability of the movement.
[0098] It is understood that the first electrical connection terminal may be, but is not limited to, a pad structure on the movable member 1222, and the second electrical connection terminal may be, but is not limited to, a pad structure on the fixed member 1221. External circuitry may be, but is not limited to, electrically connected to the second electrical connection terminal via the flexible circuit board 1203.
[0099] It is understood that the external circuit can provide power to the image sensor 210 and can also transmit control signals to the image sensor 210 so that the control chip of the camera module 10 and the control chip of the electronic device 1 can control the image sensor 210.
[0100] In the camera assembly 100 of this application embodiment, the external circuit can be electrically connected to the image sensor 210 through the elastic connector 123. The elastic connector 123 can be used as an elastic damping element or as an electrical connector. The elastic connector 123 is reused to realize the miniaturized design of the camera assembly 100.
[0101] like Figure 14 As shown, each group of suspension wires may include multiple suspension wires 1231, which are arranged side by side. These multiple suspension wires 1231 not only physically connect the fixed component 1221 and the movable component 1222, but also provide electrical connections between them. The multiple suspension wires 1231 in each group can be spaced apart, meaning that adjacent suspension wires 1231 are isolated from each other, ensuring that the transmission of power or signals by the multiple suspension wires 1231 is not affected.
[0102] Optionally, the elastic connector 123 may also include, but is not limited to, various springs. Each elastic connector 123 may include one or more sub-elastic connectors, and each elastic connector 123 may be formed by spiraling multiple elastic wires. In this case, the first end a1 of the elastic connector 123 may be one end formed by multiple elastic wires, and the second end a2 may be another end formed by multiple elastic wires. Of course, in actual production, each elastic connector 123 may also be formed by only one spring. The specific structure of the elastic connector 123 is not limited in the embodiments of this application. Any structure of the elastic connector 123 that can withstand the force generated by the movement of the movable part 1222 under the drive of the drive assembly 170 and has elastic restoring force is within the protection scope of the embodiments of this application.
[0103] It is understood that the projection of the first end a1 of each elastic connector 123 onto the movable member 1222 can be offset from its second end a2, for example, the two can be distributed on different sides of the movable member 1222. Each elastic connector 123 is connected to one side of the fixed member 1221 and the other side of the movable member 1222 corresponding to that side. Each elastic connector 123 can form a torsion spring structure, and the multiple elastic connectors 123 exert a greater pulling force on the movable member 1222, which can improve the stability of the movable member 1222.
[0104] It is understandable that, such as Figure 12As shown, each elastic connector 123 may include a first elastic portion b1, a first corner portion b2, and a second elastic portion b3 connected in sequence. The first elastic portion b1 may be connected to the fixed member 1221, and the second elastic portion b3 may be connected to the movable member 1222. The first line connecting the first elastic portion b1 and the first corner portion b2 and the second line connecting the first corner portion b2 and the second elastic portion b3 may form a preset angle, which may be, but is not limited to, ninety degrees. The elastic connector 123 of this embodiment includes the above three parts. The elastic connector 123 can form a torsion spring structure with a large amplitude. The elastic connector 123 exerts a greater pulling force on the movable member 1222, and the elastic connector 123 can further ensure the stability of the movable member 1222.
[0105] To further improve the stability of the movable component 1222, multiple elastic connectors 123 on the support plate 122 can be sequentially arranged around the outer periphery of the movable component 1222. For example, as Figure 12 As shown. Multiple elastic connectors 123 can be arranged clockwise around the outer periphery of the movable member 1222, and the multiple elastic connectors 123 can be arranged clockwise in the order of first end, second end, first end, second end… Of course, the multiple elastic connectors can also be arranged counterclockwise around the outer periphery of the movable member 1222, in which case the multiple elastic connectors 123 can be arranged counterclockwise in the order of first end, second end, first end, second end…
[0106] In two adjacent elastic connectors 123, the second end a2 of one elastic connector 123 (e.g., the preceding elastic connector 123) and the projection of the first end a1 of the other elastic connector 123 (e.g., the following elastic connector 123) onto the movable member 1222 can be adjacent and located on the same side of the movable member 1222. It can be understood that "adjacent" here means that the distance between the first end a1 of the preceding elastic connector 123 and the second end a2 of the following elastic connector 123 can be within a small preset range, so that the elastic torque of the two adjacent elastic connectors 123 can cover the entire side of the movable member 1222, resulting in better stability of the movable member 1222.
[0107] When the fixed member 1221 is a rectangular frame structure and the movable member 1222 is a rectangular plate structure, the corresponding bearing plate 122 may include four elastic connectors 123. Thus, each elastic connector 123 is connected to one side of the fixed member 1221 and the adjacent side of the movable member 1222 corresponding to that side. Each elastic connector 123 may include a set of suspension wires. On the one hand, the set of suspension wires can provide traction force for the movement of the movable member 1222 and improve the stability of the movable member 1222. On the other hand, the set of suspension wires can also prevent the movement amplitude of the movable member 1222 from being too large, causing the elastic connector 123 to separate from the movable member 1222.
[0108] It should be noted that the above is merely an exemplary connection method between the elastic connector 123 and the movable member 1222 and the fixed member 1221 in this application embodiment. The specific connection method of the elastic connector 123 is not limited to the above description. For example, the elastic connector 123 can also be directly connected to one side of the fixed member 1221 and the corresponding side of the movable member 1222. This application embodiment does not limit the specific connection method of the elastic connector 123.
[0109] This application also provides an electronic device; please refer to [link / reference]. Figure 15 , Figure 15 This is a schematic diagram of the structure of an electronic device provided in an embodiment of this application. The electronic device 1 includes a housing 20 and a camera module 10. The camera module 10 is mounted on the housing 20. The camera module 10 is any of the camera modules 10 described in the above embodiments, and will not be repeated here.
[0110] To better understand the electronic device in this embodiment, electronic device 1 will be used as a mobile phone example below. Figure 15 As shown, in addition to the camera module 10 described in the above embodiments, the electronic device 1 may also include a display screen 30, a battery 40, and a motherboard 50. It should be noted that the rear camera of the electronic device can also be the camera module described in the above embodiments. Of course, the electronic device may only have a front camera or a rear camera, or it may be the camera module described in the above embodiments.
[0111] The housing 20 may include a middle frame 21 and a rear housing 22. The display screen 30 may be disposed on one side of the middle frame 21, and the rear housing 22 may be disposed on the other side of the middle frame 21. For example, the display screen 30 and the rear housing 22 may be disposed on opposite sides of the middle frame 21 by means of adhesive bonding, welding, or snap-fitting. The camera module 10 may be disposed between the display screen 30 and the rear housing 22 and may be able to receive light from the external environment.
[0112] The back cover 22 can be the battery cover of the electronic device 1. Its material can be glass, metal, hard plastic, or other electrochromic materials. The back cover 22 has a certain structural strength and is mainly used to protect the electronic device 1. Correspondingly, the middle frame 21 can also be made of glass, metal, hard plastic, etc. The middle frame 21 also has a certain structural strength and is mainly used to support and fix the camera module 10 and other functional components installed between the middle frame 21 and the back cover 22. For example, the battery 40, motherboard 50, and antenna of the electronic device 1. Furthermore, since the middle frame 21 and the back cover 22 are generally directly exposed to the external environment, the materials of the middle frame 21 and the back cover 22 can preferably have certain wear-resistant, corrosion-resistant, and scratch-resistant properties, or a layer of wear-resistant, corrosion-resistant, and scratch-resistant functional material can be coated on the outer surface of the middle frame 21 and the back cover 22 (i.e., the outer surface of the electronic device 1).
[0113] The display screen 30 may include a display module and circuitry for responding to touch operations on the display module. The display screen 30 may use an organic light-emitting diode (OLED) screen for image display or a liquid crystal display (LCD) screen for image display. Furthermore, the display screen 30 may be a flat panel screen, a curved screen, or a quad-curved screen; this embodiment does not limit the specific form factor.
[0114] It should be noted that, for mobile phones, the aforementioned flat screen refers to the display screen 30 being flat in shape as a whole; the aforementioned dual-curved screen refers to the left and right edges of the display screen 30 being curved, while other areas remain flat. This not only reduces the black borders of the display screen 30 and increases the visible area of the display screen 30, but also enhances the aesthetics and grip of the electronic device 1; the aforementioned quad-curved screen refers to the top, bottom, left, and right edges of the display screen 30 being curved, while other areas remain flat. This not only further reduces the black borders of the display screen 30 and increases the visible area of the display screen 30, but also further enhances the aesthetics and grip of the electronic device 1.
[0115] The motherboard 50 can be housed within the casing 20, and can serve as the main control circuit board for the electronic device 1. The motherboard 50 may integrate a processor, and may also integrate one or more functional components such as a headphone jack, accelerometer, gyroscope, and motor. The processor on the motherboard 50 can control the display screen 30 and the camera module 10.
[0116] The battery 40 can be housed within the casing 20 and electrically connected to the motherboard 50 to power the electronic device 1. The motherboard 50 may contain a battery management circuit. This circuit distributes the voltage supplied by the battery 40 to the various electronic components within the electronic device 1.
[0117] It is understood that the above is only an exemplary example of electronic device 1. Electronic device 1 in the embodiments of this application may also include components such as sensors, sound-to-electric conversion devices, and antenna modules. These components can be referred to in the description of related technologies, and will not be repeated here.
