As an important component for video or shooting in electronic devices, the performance of the camera module is related to the user experience. For the performance of electronic devices, in addition to conventional pixel indicators, aperture size, sensor volume, etc. have gradually become important indicators for evaluating the performance of electronic devices. For the aperture size problem, the imaging effect of electronic devices under low ambient light sources is usually improved by increasing the aperture to increase the amount of light entering, but blindly increasing the aperture may have problems with edge image quality and highlight overflow, which will lead to a shorter depth of field, and the details cannot be fully presented in a high-brightness environment, making the blur caused by defocus more severe, and the depth of focus process more difficult; and reducing the aperture will inevitably affect the imaging effect of electronic devices, making it impossible for existing camera modules to take into account the shooting effect under a small aperture and the edge image quality and highlight overflow under a large aperture.

[0059] Referring to FIG. 1 and FIG. 2 , in some embodiments, the electronic device 100 is a smart phone, and the electronic device 100 includes a housing 10, a camera module 20, and a display screen module 30. The camera module 20 is mounted on the housing 10, and the camera module 20 can be used to perform a shooting function. The housing 10 may include components such as a middle frame 11 and a back cover 12, and the back cover 12 is connected to the middle frame 11, and together encloses an open box structure to form a space for accommodating structural parts such as a motherboard (not shown) and a battery (not shown) of the electronic device 100. The battery is used to power the display screen module 30 and the motherboard, and the camera module 20 is connected to the motherboard. The display screen module 30 and the back cover 12 are arranged on opposite sides of the middle frame 11.

[0060] It should be noted that the camera module 20 can be a front camera or a rear camera. In some embodiments, the electronic device 100 has both a front camera and a rear camera.

[0061] As shown in FIG. 1 , in some embodiments, a camera module 20 is disposed on one side of the display screen module 30 , and the camera module 20 disposed on the side of the display screen module 30 can perform the function of a front camera module. For example, a user can use the camera module 20 to take selfies, make video calls, and other operations.

[0062] As shown in FIG2 , in some embodiments, a camera assembly 20 is disposed on one side of the back cover 12, and the camera module 20 disposed on the side of the back cover 12 can be used to perform the functions of a rear camera module. For example, a user can use the camera module 20 to perform operations such as close-up and long-range shooting or video recording.

[0063] It should be noted that the electronic device 100 may be a tablet computer, a laptop computer, etc. in addition to a smart phone. In some embodiments, the electronic device 100 may not have a display screen module 30, that is, the display screen module 30 may be omitted. In this case, the electronic device 100 does not have a display function, but can still achieve a shooting function through the camera module 20.

[0064] For ease of understanding, the electronic device 100 is taken as a smart phone as an example to describe the electronic device 100 and the camera module 20. However, it is understandable that the camera module 20 disclosed in the present application is also applicable to other types of electronic devices 100.

[0065] As shown in FIG3 , the present application provides a camera module 20, including a lens 21, a lens holder 22, and an adjustable aperture 23. The lens 21 has a light hole 21a and is mounted on the lens holder 22. The adjustable aperture 23 has an aperture hole 23a, and the diameter of the aperture hole 23a is adjustable. The adjustable aperture 23 is then set in the optical path of the camera module 20 to achieve the purpose of adjusting the amount of light passing.

[0066] In some embodiments, the adjustable aperture 23 is disposed corresponding to the light incident side of the lens 21 and is used to adjust the amount of light entering the lens 21. The aperture hole 23a is opposite to the light hole 21a, and the size of the aperture hole 23a is related to the amount of light entering the lens 21.

[0067] In the adjustable aperture 23 of the embodiment of the present application, the size of the aperture hole 23 a can be adjusted, so as to adjust the amount of light entering the lens 21 .

[0068] As shown in combination with FIG. 4 and FIG. 5 , the adjustable aperture 23 includes a variable cavity 231 and a joint 232. The variable cavity 231 is annular, and the hole enclosed by its inner edge is the aperture hole 23a. In this embodiment, the variable cavity 231 includes an inner ring member 2311 and an outer ring member 2312 connected to each other. Based on the inner ring member 2311 as the inner ring structural member of the variable cavity 231, the inner ring member 2311 encloses the aperture hole 23a.

[0069] The inner ring member 2311 is elastic so that the diameter of the aperture hole 23a is adjustable. The outer ring member 2312 is arranged around the outer side of the inner ring member 2311. The variable cavity 231 has a sealed cavity 231a, which is located between the inner ring member 2311 and the outer ring member 2312.

[0070] The joint 232 is connected to the variable cavity 231 and is located outside the aperture 23a. The joint 232 has a lumen, which is connected to the sealing cavity 231a. The joint 232 is used to connect the pump body 28, and inject the fluid medium into the sealing cavity 231a or extract the fluid medium under the action of the pump body 28. When the joint 232 injects the fluid medium into the sealing cavity 231a, the inner ring member 2311 contracts along the radial direction of the aperture 23a under the pressure of the fluid medium, thereby reducing the aperture 23a. When the joint 232 injects the fluid medium into the sealing cavity 231a, the inner ring member 2311 expands along the radial direction of the aperture 23a, thereby increasing the aperture 23a.

[0071] Since the inner ring member 2311 encloses the aperture hole 23a and the inner ring member 2311 is elastic, the diameter of the inner ring member 2311 can be changed by pressure to achieve the effect of adjusting the diameter of the aperture hole 23a. In the embodiment of the present application, the fluid medium is injected into the sealed cavity 231a or the fluid medium is extracted through the joint 232, so that the aperture hole 23a enclosed by the inner ring member 2311 is reduced or increased. Therefore, this adjustable aperture 23 has a simple structure and is easy to adjust, which is conducive to reducing power consumption.

[0072] It should be noted that the fluid medium can be either gas or liquid, as long as it can be injected into the sealed cavity 231a or discharged from the sealed cavity 231a through the joint 232. It is understandable that the pump body 28 adapted to injecting gas into the sealed cavity 231a can be an air pump; correspondingly, the pump body 28 adapted to injecting liquid into the sealed cavity 231a can be a liquid pump. The types of the pump body 28 and the fluid medium are not limited here. As long as the fluid medium can be injected into the sealed cavity 231a, the inner ring member 2311 is squeezed to reduce the aperture 23a, and when the fluid medium is discharged from the sealed cavity 231a, the inner ring member 2311 expands along the radial direction of the aperture 23a to increase the aperture 23a.

[0073] In some embodiments, the outer ring 2312 is a fixed ring, and the diameter of the fixed ring is not variable. It can be understood that when the joint 232 injects the fluid medium into the sealed cavity 231a, the fluid medium fills the sealed cavity 231a, and then squeezes the inner wall of the sealed cavity 231a. Since the outer ring 2312 is a fixed ring, the diameter of the fixed ring is not variable. Therefore, the squeezing effect of the fluid medium can be converted into the power to drive the inner ring 2311 to shrink inward as much as possible, and then the aperture 23a is reduced. Since the fluid medium needs to be provided with a power source through the pump body 28 when it is injected from the joint 232 into the sealed cavity 231a, the higher the conversion rate of converting the squeezing effect of the fluid medium into the power to drive the inner ring 2311 to shrink inward, the higher the energy utilization rate. It can be seen that the outer ring 2312 is a fixed ring, and the diameter of the fixed ring is not variable. Under this structural setting, energy utilization is improved, that is, energy damage is reduced, which is conducive to further reducing power consumption and improving the battery life performance of the electronic device 100.

[0074] Continuing with FIG. 4 and FIG. 5 , in some embodiments, the inner ring member 2311 includes a plug-in portion 23111 and a sleeve portion 23112. One end of the plug-in portion 23111 is connected to one end of the sleeve portion 23112, and the other end is movably inserted into the other end of the sleeve portion 23112. Since the inner ring member 2311 is elastic, when the inner ring member 2311 is squeezed by the fluid medium injected into the sealing cavity 231a, the plug-in portion 23111 will move toward the sleeve portion 23112, so that the diameter of the inner ring member 2311 is reduced. Since the inner ring member 2311 encloses the aperture hole 23a, the diameter of the aperture hole 23a is reduced at this time to achieve the purpose of reducing the aperture hole 23a. Accordingly, when the fluid medium is drawn out from the sealing cavity 231a, as the fluid medium in the sealing cavity 231a is drawn out, the pressure of the fluid medium on the inner ring member 2311 gradually decreases. Then, the inner ring member 2311 recovers its deformation under the action of its own elastic force. At this time, the plug-in portion 23111 moves outward relative to the sleeve portion 23112. Therefore, the diameter of the inner ring member 2311 increases to achieve the purpose of increasing the aperture hole 23a.

[0075] It should be noted that the structure of the inner ring member 2311 is not limited to the above structure. For example, in some embodiments, the inner ring member 2311 is adapted to increase and decrease its diameter by a folding and telescopic structure. The inner ring member 2311 includes a metal tube, and the tube wall of the metal tube is at least partially wavy in the circumferential direction. Therefore, the inner ring member 2311 shrinks as a whole when subjected to radial extrusion force. In view of the elasticity of the inner ring member 2311, it will store elastic potential energy by deformation when subjected to extrusion. Therefore, when the fluid medium is drawn out of the sealed cavity 231a, the reduction of the fluid medium in the sealed cavity 231a will also reduce the extrusion of the inner ring member 2311, and then the inner ring member 2311 will recover the deformation under the action of its own elastic potential energy to increase the diameter. Therefore, the inner ring member 2311 set by this structure can also meet the need to adjust the diameter of the aperture hole 23a.

[0076] The structure of the inner ring member 2311 is not described in detail here. For example, in some embodiments, the metal tube can be replaced with an elastic plastic tube. A similar structure can still meet the requirement of adjustable diameter of the aperture hole 23a.

[0077] In the embodiment of the present application, the number of the joints 232 may be 1, or 2 or more. By increasing the number of the joints 232, the efficiency of injecting the fluid medium into the sealed cavity 231a or extracting the fluid medium from the sealed cavity 231a can be improved, so as to achieve the effect of improving the adjustment efficiency of the aperture hole 23a.

[0078] For example, as shown in FIG. 6 , in some embodiments, the adjustable aperture 23 includes two joints 232. The two joints 232 may be connected to the outer ring member 2312. The two joints 232 are arranged on the outer ring member 2312 at intervals of 180° from the circumference of the outer ring member 2312. In some embodiments, the two joints 232 may also be arranged on the outer ring member 2312 at intervals of 90° from the circumference of the outer ring member 2312. The number and arrangement positions of the joints 232 are not limited herein.

[0079] In some embodiments, the outer ring member 2312 is connected to the lens 21, and the outer ring member 2312 is arranged around the circumference of the light-through hole 21a, so that the aperture hole 23a is opposite to the light-through hole 21a. The outer ring member 2312 can be connected to the lens 21 by means of threads or snaps. Under this structural setting, the adjustable aperture 23 can be quickly assembled to the lens 21, or disassembled from the lens 21, so as to facilitate the maintenance of the adjustable aperture 23. For example, when the structure of the adjustable aperture 23 is damaged, the damaged adjustable aperture 23 can be disassembled and then replaced with a new adjustable aperture 23, so that the entire camera module 20 does not need to be scrapped, and the performance of the adjustable aperture of the camera module 20 can still be maintained.

[0080] In some embodiments, the lens 21 may include a lens barrel (not shown) and a plurality of lenses (not shown), the plurality of lenses are arranged along the axis direction of the lens barrel, and the optical axes of the lenses are parallel to the axis of the lens barrel. In this embodiment, the outer ring member 2312 may be connected to the lens barrel of the lens 21. The connection between the outer ring member 2312 and the lens barrel includes, but is not limited to, threaded connection, snap connection, glue bonding, or sleeve connection.

[0081] It should be noted that the camera module 20 may also include other structures. For example, referring to FIG. 3 again, in some embodiments, the camera module 20 further includes a circuit board 24 and an image sensor 25 , and the image sensor 25 is disposed on the circuit board 24 .

[0082] It is understandable that the image sensor 25 is arranged on the image side of the lens 21 along the optical axis of the lens 21. In this way, the external light can be transmitted to the image sensor 25 through the lens 21, and the image sensor 25 can convert the light signal into an electrical signal, and then form an image that can be presented by the electronic device 1001 after processing. The image sensor 25 includes but is not limited to a charge coupled device (CCD) or a complementary metal oxide semiconductor device (CMOS Sensor).

[0083] In some embodiments, the camera module 20 includes a driving mechanism 26 and a filter assembly 27. The lens 21 is mounted on the driving mechanism 26, and the driving mechanism 26 is used to drive the lens 21 to move. The driving mechanism 26 can be a voice coil motor or a piezoelectric driver, etc., which is not specifically limited here.

[0084] The driving mechanism 26 can drive the lens 21 to move, thereby changing the distance between the lens 21 and the image sensor 25, thereby achieving a focusing effect.

[0085] The filter assembly 27 is disposed between the circuit board 24 and the lens 21. External light can be transmitted to the filter assembly 27 through the lens 21, and the filter assembly 27 can filter light of a specific wavelength. The light filtered by the filter assembly 27 is transmitted to the image sensor 25 and converted into an electrical signal. By providing the filter assembly 27, the invisible light part of the light that can be received by the image sensor 25 can be filtered to ensure the imaging quality.

[0086] In some embodiments, the filter assembly 27 includes a receiving seat 271 and a filter 272. The filter 272 is disposed on the receiving seat 271, and the receiving seat 271 may be disposed between the circuit board 24 and the driving mechanism 26, so that the lens 21 connected to the driving mechanism 26 is located on the side of the filter 272 that is away from the image sensor 25. In other words, the filter 272 is correspondingly disposed between the lens 21 and the image sensor 25, so that the light incident on the filter 272 from the lens 21 can be transmitted to the image sensor 25 after being filtered by the filter 272.

[0087] As shown in combination with FIG. 7 and FIG. 8 , in some embodiments, the camera module 20 further includes a pump body 28, which is connected to the connector 232. The pump body 28 is used to inject a fluid medium into the sealed cavity 231a or extract the fluid medium through the connector 232, thereby adjusting the volume of the fluid medium in the sealed cavity 231a, so as to change the pressure of the fluid medium on the inner ring member 2311, so that the inner ring member 2311 can adapt to the adjustment of the diameter of the aperture hole 23a under its own elasticity. In this embodiment, the pump body 28 can be set on the outer wall of the lens holder 22.

[0088] It should be noted here that, in some embodiments, when the fluid medium is air, the electronic device 100 is provided with a circulation channel connecting the pump body 28 with the outside world. The form of the circulation channel includes but is not limited to an air pipe, an air hole or an assembly gap between structural parts. That is to say, for the camera module 20 and the electronic device 100 of the present application, whether the fluid medium is gas or liquid, the corresponding configuration will be configured around the purpose of enabling the adjustable aperture 23 to adapt to the injection or extraction of the fluid medium to achieve the purpose of adjusting the size of the aperture hole 23a. For example, when the fluid medium is liquid, considering that the electronic device 100 is in a non-underwater environment during daily use, at this time, a matching container can be configured inside or outside the housing 10 of the electronic device 100, and the container can be used to provide liquid for the pump body 28 to meet the needs of the pump body 28 to inject the liquid in the container into the sealed cavity 231a or to extract it from the sealed cavity 231a to the container.

[0089] There is no limitation on the location between the container and the pump body 28, as long as the need to inject the fluid medium into the sealing cavity 231a or to extract the fluid medium can be met.

[0090] In some embodiments, the pump body 28 may also be disposed in the electronic device 100 . When the structure of the camera module 20 other than the pump body 28 is assembled to the electronic device 100 , the pump body 28 may be connected to the connector 232 .

[0091] There is no limitation on the installation position and installation method of the pump body 28 , as long as the pump body 28 can inject the fluid medium into the sealing cavity 231 a or extract the fluid medium through the joint 232 .

[0092] Continuing with FIG. 7 and FIG. 8 , the camera module 20 further includes a valve 29, which is used to open or close the passage between the pump body 28 and the connector 232. The valve 29 is disposed in the pipeline between the pump body 28 and the connector 232, or the valve 29 is disposed in the pump body 28. In this embodiment, the valve 29 is used to control the time for the pump body 28 to inject the fluid medium into the sealed cavity 231a through the connector 232, thereby improving the convenience of operation of the adjustable aperture 23.

[0093] Furthermore, the valve 29 is a solenoid valve, and the valve 29 is in a normally closed state when it is not powered. In this way, after the pump body 28 is used to inject the fluid medium into the sealed cavity 231a or to extract the fluid medium from the joint 232 to complete the size adjustment of the aperture hole 23a of the adjustable aperture 23, the valve 29 can be controlled to be in a non-powered state. At this time, since the valve 29 is in a normally closed state, the volume of the fluid medium in the sealed cavity 231a will not change, so as to maintain the size of the aperture hole 23a unchanged. Under this structural setting, the valve 29 does not need long-term power supply control, and can keep the size of the adjusted aperture hole 23a unchanged, so as to further reduce the power consumption of the adjustable aperture 23, so as to extend the battery life of the electronic device 100.

[0094] It should be noted that, in some embodiments, the fluid medium in the sealing cavity 231a can be squeezed out of the sealing cavity 231a when the inner ring 2311 expands under its own elastic force. In this embodiment, the sealing cavity 231a can be filled with fluid medium through the joint 232, and can also be discharged through the joint 232. In some embodiments, another joint 232 can be provided to meet the need of discharging the fluid medium from the sealing cavity 231a.

[0095] The pipeline between the pump body 28 and the joint 232 can be used as long as it can adapt to the pump body 28 injecting the fluid medium into the sealed cavity 231a through the joint 232. For example, as shown in Figures 7 and 8, the sealed cavity 231a body is connected to two valves 29 through two joints 232 respectively through the first pipeline 201 and the second pipeline 202, and the two valves 29 can be connected to the pump body 28. In this way, when the two valves 29 are open, the pump body 28 can inject the fluid medium into the sealed cavity 231a body or extract the fluid medium through the first pipeline 201 and the second pipeline 202, so as to adjust the volume of the fluid medium in the sealed cavity 231a, so as to adjust the pressure of the inner ring member 2311, and then adjust the diameter of the aperture 23a surrounded by the inner ring member 2311.

[0096] It should be noted here that the flow rates of the two joints 232 are controlled by controlling the two valves 29 so as to ensure the uniformity of the fluid medium in the sealed cavity 231a, and then the inner ring member 2311 can maintain the coaxiality between the aperture hole 23a and the optical axis of the lens 21 when adjusting the diameter of the aperture hole 23a, so as to maintain a good shooting effect.

[0097] There are many implementations for the location and manner of setting the first pipeline 201 and the second pipeline 202 , as long as the requirement of the adjustable aperture 23 for adjusting the diameter of the aperture hole 23 a can be met.

[0098] For ease of understanding, the following is an exemplary description of the locations of the first pipeline 201 and the second pipeline 202, but it does not mean that the locations of the first pipeline 201 and the second pipeline 202 are limited thereto.

[0099] For example, as shown in combination with FIG. 7 and FIG. 8 , the first pipeline 201 is arranged outside the lens 21 and extends along the lens seat 22 toward the pump body 28. In this embodiment, the valve 29 is arranged in the lens seat 22, and one end of the first pipeline 201 penetrates the wall thickness of the lens seat 22 to be connected with the valve 29. The valve 29 is connected to the pump body 28. In this way, when the valve 29 opens the first pipeline 201, the first pipeline 201 conducts the passage between the pump body 28 and the joint 232.

[0100] The second pipeline 202 can be arranged in the same manner as the first pipeline 201, or in a different manner. For example, in the camera module 20 shown in Figures 7 and 8, the second pipeline 202 is arranged in a different manner from the first pipeline 201. Specifically, part of the second pipeline 202 is buried in the lens barrel of the lens 21. For another example, in combination with Figures 9 and 10, the second pipeline 202 is arranged in the same manner as the first pipeline 201. A gap 203 is formed between the driving mechanism 26 and the bottom end of the lens holder 22. Part of the structure of the first pipeline 201 and / or the second pipeline 202 is penetrated in the gap 203. The first pipeline 201 and the second pipeline 202 are both buried in the lens barrel of the lens 21 and pass through the gap 203. In this embodiment, the gap 203 between the driving mechanism 26 and the lens holder 22 is used to meet the needs of pipeline arrangement, thereby improving the space utilization rate inside the camera module 20.

[0101] The adjustable aperture 23 is not limited to being arranged on the light incident side of the lens 21, but may also be arranged on the light exiting side of the lens 21. Based on this, any camera module 20 including the adjustable aperture 23 of the present application is within the protection scope of the embodiments of the present application.

[0102] For example, as shown in combination with FIG. 9 and FIG. 10 , the lens 21 and the filter assembly 27 are spaced apart from each other, that is, there is a gap 204 between the two.

[0103] In some embodiments, the gap 204 may be provided with an adjustable aperture 23, so that the adjustable aperture 23 is provided inside the camera module 20. Since the location of the filter 272 of the camera module 20 has a cleanliness requirement, that is, there is little dust here to ensure the image quality. Therefore, the adjustable aperture 23 is provided between the lens 21 and the filter assembly 27, which is conducive to ensuring that the adjustable aperture 23 remains clean.

[0104] There are various implementations for the structure of the variable cavity 231 .

[0105] Referring again to FIG. 4 and FIG. 5 , in some embodiments, the variable cavity 231 includes an annular capsule 2313, the annular capsule 2313 is connected between the inner ring member 2311 and the outer ring member 2312, and the sealed cavity 231a is the cavity of the annular capsule 2313. In this way, the joint 232 injects the fluid medium into the sealed cavity 231a, that is, the joint 232 injects the fluid medium into the cavity, thereby expanding the annular capsule 2313. Since the annular capsule 2313 is connected between the inner ring member 2311 and the outer ring member 2312, the annular capsule 2313 will apply pressure to the inner ring member 2311 during the expansion process, so that the inner ring member 2311 shrinks, thereby achieving the purpose of reducing the aperture hole 23a.

[0106] Correspondingly, when the fluid medium in the sac cavity flows out of the sac cavity through the joint 232, the pressure of the annular sac 2313 on the inner ring member 2311 is reduced, so that the inner ring member 2311 recovers its deformation under the action of its own elasticity, that is, the aperture hole 23a enclosed by the inner ring member 2311 is enlarged.

[0107] The variable cavity 231 is not limited to the above structure to adjust the diameter of the aperture hole 23 a.

[0108] For example, as shown in combination with FIG. 11 and FIG. 12, the variable cavity 231 includes at least two connecting rings 2314, which are arranged at intervals along the extension direction of the center line of the aperture hole 23a, and are all arranged around the inner ring member 2311 and the outer ring member 2312, and the connecting ring 2314, the inner ring member 2311 and the outer ring member 2312 form a sealed cavity 231a. In this embodiment, the connecting ring 2314 is used to form a sealed cavity 231a between the inner ring member 2311 and the outer ring member 2312. Since the inner ring member 2311 constitutes a part of the side wall of the sealed cavity 231a, when the fluid medium in the sealed cavity 231a increases, the fluid medium generates an increased pressure on the inner ring member 2311, so that the elastic inner ring member 2311 contracts to achieve a reduction in the diameter of the aperture hole 23a. Accordingly, when the fluid medium flows out of the sealing cavity 231a, the pressure of the fluid medium on the inner ring member 2311 decreases as the fluid medium flows out. Thus, the inner ring member 2311 recovers its deformation under its own elasticity, that is, expands outward, thereby increasing the diameter of the aperture 23a.

[0109] It should be noted that the connecting ring 2314 can be made of elastic material, so that it can adapt to the changes in the volume of the fluid medium in the sealing cavity 231a. During the contraction or expansion of the inner ring 2311 relative to the outer ring 2312, the connecting ring 2314 can adapt to the need of deformation and maintain the connection between the inner ring 2311 and the outer ring 2312, thereby maintaining the structural stability of the variable cavity 231, so that the sealing performance of the sealing cavity 231a is not easily affected by the contraction or expansion of the inner ring 2311.

[0110] In addition to using elastic materials to adapt to the contraction or expansion of the inner ring member 2311, the connecting ring 2314 can also adapt to the diameter change of the inner ring member 2311 through other methods such as folding or telescoping.

[0111] For example, as shown in combination with FIG. 13 and FIG. 14 , the connection ring 2314 includes a foldable portion 2315, and the folding line of the foldable portion 2315 is arranged around the center line of the aperture hole 23a. When the inner ring member 2311 contracts, the foldable portion 2315 is unfolded; when the inner ring member 2311 expands, the foldable portion 2315 is folded. In this embodiment, the foldable portion 2315 of the connection ring 2314 has a state change of unfolding and folding, so that the connection ring 2314 can be adaptively unfolded and folded under the action of force to maintain the connection stability between the inner ring member 2311 and the outer ring member 2312, and then maintain the stability and reliability of the sealed cavity 231a of the variable cavity 231 when injecting or discharging the fluid medium, so as to facilitate the inner ring member 2311 to stably adjust the diameter of the aperture hole 23a surrounded by it, thereby improving the shooting effect of the camera module 20.

[0112] Further, the adjustable aperture 23 has an initial state. In the initial state, the inner ring 2311 has an expansion force to expand outward, and the connecting ring 2314 has an extrusion force to squeeze the inner ring 2311 inward. The magnitude of the expansion force and the magnitude of the extrusion force are such that the diameter of the aperture hole 23a is maintained at the initial diameter. Based on this initial state, the expansion force of the inner ring 2311 and the extrusion force of the connecting ring 2314 form a balanced force, so that the inner ring 2311 and the connecting ring 2314 are in an elastic floating state. At this time, only a small force is required to adjust the diameter of the inner ring 2311, that is, to achieve the effect of adjusting the diameter of the aperture hole 23a. Therefore, when the pump body 28 injects or extracts the fluid medium into the sealed cavity 231a through the joint 232, the pump body 28 only needs to overcome a small force, so that the fluid medium is smoother and has low energy consumption when entering and exiting the sealed cavity 231a, so as to further reduce the power consumption of the adjustable aperture 23 during the adjustment process.

[0113] As shown in combination with FIG. 15 and FIG. 16 , in some embodiments, the variable cavity 231 further includes a film sleeve 2316. The film sleeve 2316 is sleeved on the outer periphery of the inner ring 2311, and the two ends of the film sleeve 2316 are respectively sealed and connected between two adjacent connecting rings 2314. In this embodiment, the film sleeve 2316 is used to enhance the stability between the first connecting ring 2314 and the second connecting ring 2314, so as to facilitate the stability of the overall structure of the variable cavity 231, so that when the variable cavity 231 is injected with a fluid medium or discharged with a fluid medium, the overall contraction or expansion is relatively uniform, so as to facilitate the roundness of the aperture hole 23a enclosed by the inner ring 2311.

[0114] It should be noted that, in an embodiment where the connecting ring 2314 includes a foldable portion 2315, the membrane sleeve 2316 can be connected between the foldable portions 2315 corresponding to the two connecting rings 2314 to achieve the effect of stabilizing the foldable portions 2315, so as to improve the stability of the connecting ring 2314 during the contraction or expansion movement, which in turn helps to improve the stability of the inner ring 2311 in adjusting the diameter of the aperture hole 23a.

[0115] Furthermore, the variable cavity 231 includes a plurality of membrane sleeves 2316, which are arranged in a sleeve connection with each other and divide the sealed cavity 231a into a plurality of sub-cavities 231b. The plurality of sub-cavities 231b are all connected to the tube cavity, and then the joint 232 can inject or discharge the fluid medium into each sub-cavity 231b through the tube cavity, so as to improve the stability of the expansion or contraction of the variable cavity 231, so that the inner ring member 2311 can adjust the diameter of the aperture hole 23a more stably.

[0116] The number of the film sleeves 2316 may be two or more. For example, as shown in FIG. 17 and FIG. 18 , the variable cavity 231 includes two film sleeves 2316, and the sealed cavity 231a is divided into three annular sub-containers by the two film sleeves 2316. The number of the film sleeves 2316 is not limited here.

[0117] Referring to FIG. 19 , FIG. 19 is a schematic diagram of the structure of an electronic device 100 provided in an embodiment of the present application.

Accordingly, the memory 502 can also include a memory controller to provide the processor 508 and the input unit 503 with access to the memory 502.

[0120] The input unit 503 can be used to receive input digital, character information or user feature information (such as fingerprints), and generate keyboard, mouse, joystick, optical or trackball signal input related to user settings and function control. Specifically, in a specific embodiment, the input unit 503 may include a touch-sensitive surface and other input devices.

Optionally, the touch-sensitive surface may include a touch detection device and a touch controller. Among them, the touch detection device detects the user's touch orientation, detects the signal brought by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device, converts it into touch point coordinates, and then sends it to the processor 508, and can receive and execute commands sent by the processor 508.

Although in Figure 19, the touch-sensitive surface and the display panel are implemented as two independent components to implement input and output functions, in some embodiments, the touch-sensitive surface can be integrated with the display panel to implement input and output functions. It can be understood that the display screen module 30 may include an input unit 503 and a display unit 504.

[0122] The electronic device 100 may also include at least one sensor 505, such as a light sensor, a motion sensor, and other sensors.

The audio circuit 506 may also include an earphone socket to provide communication between an external earphone and the electronic device 100.

[0124] Wireless Fidelity (WiFi) is a short-range wireless transmission technology. The electronic device 100 can help users send and receive emails, browse web pages, and access streaming media through the wireless fidelity module 507, which provides users with wireless broadband Internet access. Although FIG. 19 shows the wireless fidelity module 507, it is understandable that it is not a necessary component of the electronic device 100 and can be omitted as needed without changing the essence of the invention.

[0125] The processor 508 is the control center of the electronic device 100. It uses various interfaces and lines to connect various parts of the entire electronic device 100.
