[0002] Influenced by user needs, mobile phones and other electronic devices are increasingly focusing on the quality of their photographs and sound effects during their design. Among them, the zoom factor is an important factor in measuring photographic performance, and the volume of the sound cavity is an important factor in sound performance. The increase in the zoom factor and the volume of the sound cavity will cause both to occupy more installation space inside the electronic device, which will result in the overall volume and size of the electronic device being relatively large, which will have an adverse effect on the portability and feel of the electronic device. Summary of the invention

[0006] determining the operating requirements of the electronic device;

[0007] When the working requirement is an image shooting mode, the mounting seat is controlled to move in a direction away from the lens group so that the distance between the image sensor of the camera module and the lens group meets a preset zoom multiple;

[0008] When the working requirement is the sound playing mode, the mounting seat is controlled to move in a direction close to the lens group so that the volume of the closed area where the sound module is located in the variable sound cavity meets the preset sound volume.

[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0023] The electronic device provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0024] like Figure 1 and Figure 2 As shown, an embodiment of the present application discloses an electronic device, which includes a housing, a sound module and a camera module. Of course, the electronic device also includes other components such as a back cover, a battery, a display module and a mainboard 220. Considering the simplicity of the text, they are not introduced one by one here. Among them, the display module and the back cover can be arranged back to back, and the housing can be arranged between the two. The housing can provide an installation base for devices such as batteries and processors in the electronic device to ensure that a stable assembly relationship can be formed between the components. Specifically, the housing can be formed of materials such as metal or plastic, and the specific structure and shape of the housing can be determined according to parameters such as the specific structure and size of the components installed on the housing as needed, which are not limited here.

[0025] The shell has a variable sound cavity. As the name implies, the variable sound cavity is the sound cavity of the electronic device disclosed in the embodiment of the present application, and the sound cavity is relatively special, and it has the ability to change its volume. More specifically, when the shell is formed of materials such as plastic, the variable sound cavity structure can be formed together during the processing of the shell by integral injection molding and other methods. In addition, the sound module 210 is installed in the variable sound cavity, so that the variable sound cavity can provide acoustic effects for the sound module. The sound module 210 can specifically be a device with sound-generating ability such as a speaker, and its specific model and other parameters can be determined according to actual needs and are not limited here.

[0026] It should be noted that, when not affected by other components, the variable sound cavity has an initial volume, and its initial volume is its maximum volume. By setting other components such as the mounting seat mentioned below in the variable sound cavity, and changing the position of the mounting seat in the variable sound cavity, the actual volume of the sound cavity used as the sound module 210 in the variable sound cavity can be changed, thereby achieving the purpose of variable sound cavity volume. Of course, the specific shape and structure of the variable sound cavity can be determined according to the actual situation such as the specific shape of the shell, and is not limited here.

[0027] The camera module includes a lens group 310, an image sensor 320 and a mounting seat 330. The lens group 310 is mounted on the housing so that the lens group 310 can be stably mounted in the electronic device. The lens group 310 includes at least one lens 312, which can provide light distribution for the light incident into the lens group 310, so as to achieve the purpose of improving the viewing range of the lens group 310. At the same time, the lens group 310 is located outside the variable sound cavity to prevent the housing from hindering the light acquisition process of the lens group 310. Of course, the lens group 310 is also arranged to face the variable sound cavity so that the lens group 310 can cooperate with the image sensor 320 that may be located in the variable sound cavity to achieve the purpose of photosensitive imaging.

[0028] More specifically, the image sensor 320 is mounted on the mounting base 330, and the image sensor 320 can convert the optical signal into an electrical signal to ensure that the camera module has an imaging function, and the image sensor 320 is arranged toward the light-emitting side of the lens group 310 to ensure that the image sensor 320 can receive the light incident into the lens group 310. Optionally, the image sensor 320 can be fixed to the mounting base 330 by bonding or screwing, so that when the mounting base 330 moves relative to the lens group 310, the image sensor 320 can be stably driven to move together.

[0029] The mounting seat 330 is sealedly installed in the variable sound cavity, so that the mounting seat 330 can isolate the space occupied by the sound module from the space occupied by the camera module, thereby making the camera module and the sound module respectively located in two relatively independent spaces, preventing the two from interfering with each other during operation, and improving the overall performance of the camera module and the sound module.

[0030] At the same time, the mounting seat 330 is movably mounted in the variable sound cavity, and the moving direction of the mounting seat 330 relative to the variable sound cavity is the optical axis direction of the lens group 310. Based on this, during the movement of the mounting seat 330 relative to the variable sound cavity, the distance between the mounting seat 330 (the image sensor 320 thereon) and the lens group 310 can be changed, so that the zoom distance of the camera module changes. At the same time, since the mounting seat 330 is sealed with the variable sound cavity, the volume of the cavity in the variable sound cavity for providing acoustic effect to the sound module can also be changed when the mounting seat 330 moves relative to the variable sound cavity.

[0031] The embodiment of the present application discloses an electronic device, which includes a housing, a sound module and a camera module, wherein the housing has a variable sound cavity, and the sound module is installed in the variable sound cavity, and the mounting seat 330 in the camera module moves along the optical axis direction of the lens group 310 and is sealedly installed in the variable sound cavity. At the same time, the image sensor 320 in the camera module is installed on the mounting seat 330, and the image sensor 320 is located on the light-emitting side of the lens group 310 of the camera module, and then when the mounting seat 330 moves relative to the housing (i.e., the variable sound cavity), the zoom distance of the camera module and the volume of the cavity in the variable sound cavity used to provide acoustic effects for the sound module can change in reverse, which can improve the shooting performance and sound performance of the electronic device without causing the volume of the electronic device to increase too much, ensuring that the electronic device still has good portability and feel of use.

[0032] As described above, the camera module includes at least one lens 312. In the present embodiment, the lens group 310 includes a reflector 311 and at least one lens 312. The lens 312 is disposed between the reflector 311 and the image sensor 320. The light emitting direction of the reflector 311 is perpendicular to the light incident direction of the reflector 311, so as to utilize the reflector 311 to change the propagation direction of the light in the camera module. This allows the spacing between the image sensor 320 and the lens group 310 to break the limitation of the thickness size of the electronic device. When external light is incident on the camera module of the electronic device along the thickness direction of the electronic device, with the aid of the technical solution disclosed in the embodiment of the present application, the various components in the camera module can be arranged using the lateral (width direction or length direction) size of the electronic device. This can greatly expand the zoom distance of the camera module, thereby allowing the camera module to form a structure similar to that of a periscope device, thereby improving the shooting performance of the shooting module.

[0033] Based on the above-mentioned shooting module, the mounting seat 330 can be made movable relative to the shell along the emitting direction of the reflector 311. In this case, the size of the shell will no longer be restricted by the thickness of the electronic device, thereby making the size of the variable sound cavity in the zoom direction of the camera module (i.e., the optical axis direction of the lens 312) relatively larger, thereby improving the zoom distance of the camera module and the adjustable range of the total volume of the variable sound cavity, so that the zoom distance and the total volume of the cavity in the variable sound cavity used to provide acoustic effects are as large as possible, thereby improving the shooting performance and sound performance of the electronic device.

[0034] As described above, the variable sound cavity is located on the shell, and the volume of the cavity in the variable sound cavity for providing acoustic effects to the sound module 210 can be changed by adjusting the relative position between the mounting seat 330 and the shell. Since the sound module 210 is installed in the variable sound cavity, the minimum volume of the cavity in the variable sound cavity for providing acoustic effects to the sound module 210 can be made not less than a preset volume, which ensures that the sound module 210 will not be damaged by being squeezed by the mounting seat 330 on the one hand, and can also ensure that the sound module 210 can work normally on the other hand. More specifically, the variable sound cavity includes a fixed sound cavity 201, that is, the volume of the fixed sound cavity 201 is a fixed value, based on which, the sound module 210 is installed in the fixed sound cavity 201, and the fixed sound cavity 201 can provide acoustic effects for the sound module 210.

[0035] Accordingly, in order to ensure that the volume of the variable sound cavity including the fixed sound cavity 201 can change, the variable sound cavity also includes a accommodating cavity 121, the accommodating cavity 121 is connected to the fixed sound cavity 201, and the mounting seat 330 is installed in the accommodating cavity 121. Then, by changing the position of the mounting seat 330 in the accommodating cavity 121, the volume of the variable sound cavity can be changed.

[0036] More specifically, in order to ensure that the housing cavity 121 and the fixed sound cavity 201 can be formed on the housing, in detail, the housing includes a housing member 120 and a sound cavity forming member, and the housing member 120 is located on the side of the sound cavity forming member facing the lens group 310, which can simplify the structural composition of the housing, and can make the spatial structure of the variable sound cavity relatively regular, the cavity of the variable sound cavity is more open, and the communication area between the housing cavity 121 and the fixed sound cavity 201 is relatively larger, which can improve the acoustic performance of the sound module 210. The sound cavity forming member is used to form the fixed sound cavity 201, and the sound module 210 is installed in the fixed sound cavity 201, that is, in the sound cavity forming member.

[0037] Furthermore, the container 120 has the above-mentioned accommodating cavity 121. The accommodating cavity 121 of the container 120 can provide an accommodating space for the mounting seat 330 in the camera module. Furthermore, the accommodating cavity 121 can also serve as a common space for the camera module to expand the zoom ratio and the sound module to expand the sound cavity volume. Thus, the electronic device has a larger zoom ratio and a larger sound cavity volume while the volume of the electronic device will not be greatly increased, thereby ensuring that the electronic device still has a relatively small overall volume and size, thereby ensuring that the portability and feel of the electronic device are relatively good.

[0038] The container 120 may be a hollow structural member, and the cavity it has is the container cavity 121. At the same time, the container 120 also has two openings, which may be a first opening and a second opening, respectively, and the first opening and the second opening are both connected to the container cavity 121. In addition, the first opening is used to communicate with the fixed sound cavity 201 located on one side of the container 120, thereby ensuring that at least part of the volume of the container cavity 121 can be incorporated into the fixed sound cavity 201, thereby expanding the total volume of the sound cavity of the sound module, and the second opening faces the lens group 310, thereby ensuring that the light emitted from the lens group 310 can be incident from the second opening into the image sensor 320 installed on the mounting seat 330, thereby ensuring that the container cavity 121 can also expand the zoom multiple of the camera module.

[0039] Furthermore, the housing also includes a frame 110, which is the main structure of the housing, and the accommodating member 120, the sound cavity forming member and the lens group can all be installed in the frame 110. Optionally, the frame 110 is provided with an installation recessed groove, and a portion of each of the accommodating member 120, the sound cavity forming member and the lens group 310 can be located in the installation recessed groove, so that the assembly formed by the aforementioned components occupies a relatively small space in the thickness direction of the frame 110, so that the overall thickness of the electronic device is relatively small, and the compactness between the components in the electronic device can be improved. More specifically, the specific size and shape of the installation recessed groove can be flexibly determined according to parameters such as the size, shape and distribution position of the accommodating member 120, the sound cavity forming member and the lens group.

[0040] As described above, the mounting base 330 can move relative to the shell. Optionally, by providing a corresponding push-pull control lever for the mounting base 330, when it is necessary to adjust the zoom distance of the camera module or the sound cavity volume of the sound module, the mounting base 330 can be moved relative to the shell by applying a force in the corresponding direction to the push-pull control lever, thereby changing the distance between the mounting base 330 and the lens group 310.

[0041] In another embodiment of the present application, the electronic device further includes a driver, which is connected to the mounting seat 330 to drive the mounting seat 330 to move relative to the shell. In this case, the degree of automation of the electronic device can be improved. At the same time, by using the driver to drive the mounting seat 330 to move, the movement accuracy of the mounting seat 330 can also be improved, thereby improving the shooting performance and sound performance of the electronic device. The driver can specifically be a linear motor, or the driver can be a hydraulic cylinder or a pneumatic cylinder, etc. By installing the driver at one end of the mounting seat 330 and forming a fixed connection relationship between the driver and the mounting seat 330, it can be ensured that the driver can drive the mounting seat 330 to move relative to the shell.

[0042] Furthermore, the driving member is a rotating motor, and the electronic device also includes a transmission member, and the driving member is connected to the mounting base 330 through the transmission member. In this case, the driving member can be arranged on one side of the mounting base 330, and the transmission effect of the transmission member can be utilized to prevent the driving member from blocking the optical path of the image sensor 320, and can prevent the driving member from obstructing the movement range of the mounting base 330.

[0043] The transmission member may specifically include a gear 410 and a rack 420, which are transmission-connected. The gear 410 is mounted on the driving shaft of the driving member to drive the gear 410 to rotate when the driving member rotates, thereby providing a rotational driving force. The rack 420 is fixedly connected to the mounting seat 330, and the rack 420 extends along the moving direction of the mounting seat 330, so that when the gear 410 rotates, the mounting seat 330 can be indirectly driven to move along its moving direction through the rack 420. When the above technical solution is adopted, the smoothness of the movement of the mounting seat 330 can also be provided.

[0044] As described above, the mounting seat 330 is movably connected to the housing, so that the mounting seat 330 can move in the variable cavity along the optical axis direction of the lens group 310, and the variable sound cavity can provide a limiting and guiding function for the mounting seat 330. In order to further improve the movement stability of the mounting seat 330, the electronic device may further include a guide member 430, which extends along the moving direction of the mounting seat 330 (i.e., the optical axis direction of the lens group 310), and one of the mounting seat 330 and the lens group 310 is fixedly connected to the guide member 430, and the other is movably matched with the guide member 430, so that the guide member 430 is used to provide a guiding and limiting function for the movement of the mounting seat 330, thereby improving the movement stability of the mounting seat 330, and then improving the shooting accuracy and reliability of the camera module.

[0045] Specifically, the guide member 430 can be a rod-shaped structural member, which is fixedly connected to the mounting seat 330, and by setting a guide hole on the side wall of the lens group 310, the guide member 430 and the guide hole can be movably matched in the movement direction of the mounting seat 330, and can be limited in the direction perpendicular to the movement direction of the mounting seat 330.

[0046] Further, the number of guide members 430 can be multiple, and multiple guide members 430 can further improve the movement stability of the mounting seat 330. Optionally, multiple guide members 430 are arranged in a direction perpendicular to the optical axis direction of the lens group 310. In another embodiment of the present application, multiple guide members 430 can be arranged in a determinant, in which case, the guiding and limiting effect provided by the guide members 430 for the mounting seat 330 can be further improved. Specifically, the number of guide members 430 can be four, six or more, which is not limited here.

[0047] The camera module includes a flexible circuit board 510, and the flexible circuit board 510 is connected to the image sensor 320. More specifically, the flexible circuit board 510 can form a connection relationship with the image sensor 320 with the help of the guide 430 to reduce the difficulty of performing the connection work. Accordingly, the flexible circuit board 510 can also be connected to the main board 220 or the sub-board of the electronic device through the connector 520, so as to supply power to the image sensor 320 and exchange information with the image sensor 320.

[0048] During the process of assembling the electronic device, the container 120 and the lens group 310 can be spaced apart from each other. On the one hand, the zoom distance of the lens group 310 can be further increased, and on the other hand, installation space can be provided for the flexible circuit board 510, and thus the flexible circuit board 510 can be located between the container 120 and the lens group 310; at the same time, since the mounting seat 330 is located within the accommodating cavity 121 of the container 120, and the side wall of the container 120 has a thickness, a corresponding gap will also exist between the inner wall of the container 120 close to the frame 110 and the frame 110. For this reason, a gap can also be formed between the guide member 430 connected to the mounting seat 330 and the frame 110, and thus the flexible circuit board 510 can be located between the guide member 430 and the frame 110, thereby ensuring that the flexible circuit board 510 will not hinder the movement of the guide member 430 relative to the frame 110.

[0049] As described above, the mounting seat 330 is sealed and connected to the shell (or the inner wall of the variable sound cavity). Specifically, the mounting seat 330 and its shape can be adapted to the inner wall of the variable sound cavity, and by filling the gap between the two with grease, it is ensured that the mounting seat 330 can form a more reliable sealed connection relationship with the inner wall of the variable sound cavity.

[0050] In another embodiment of the present application, the elastic sealing ring 340 can also provide a sealing effect for the mounting seat 330 and the variable sound cavity, thereby improving the sealing reliability of the mounting seat 330 and the variable sound cavity. The elastic sealing ring 340 can be formed of materials such as rubber, and the elastic sealing ring 340 can be sleeved outside the mounting seat 330 to use the elastic sealing ring 340 to seal the mounting seat 330 and the housing (or the inner wall of the variable sound cavity).

[0051] Furthermore, a limiting groove is provided on the outer periphery of the mounting seat 330, and a part of the elastic sealing ring 340 is located in the limiting groove, so that the limiting groove is utilized to provide an axial limiting effect for the elastic sealing ring 340. On the one hand, it prevents the elastic sealing ring 340 from rolling or winding relative to the mounting seat 330 due to the friction force when the mounting seat 330 moves. On the other hand, it can also reduce the resistance generated by the elastic sealing ring 340 when it moves with the mounting seat 330, thereby improving the smoothness of the relative movement between the mounting seat 330 and the shell.

[0052] In addition, in order to ensure that the connection sealing between the sound cavity forming member and the shell is relatively good, a flexible sealing structural member such as foam 600 can be placed between the sound cavity forming member and the first opening of the container 120, and the sound cavity forming member and the container 120 can be squeezed to squeeze the foam 600 to ensure a stable and reliable sealing connection relationship between the sound cavity forming member and the container 120.

[0053] Meanwhile, in the above embodiment, the sound cavity forming member may be one or more. In order to reduce the difficulty of forming the fixed sound cavity 201, the number of the sound cavity forming members may be at least two, which may be respectively the mainboard bracket 230 and the mainboard 220. The mainboard bracket 230 may be a frame-type structural member. By connecting the mainboard bracket 230 upside down to the mainboard 220, the mainboard bracket 230 and the mainboard 220 may enclose the fixed sound cavity 201. Accordingly, a sealing structural member such as foam 600 may also be provided between the mainboard bracket 230 and the mainboard 220 to improve the sealing reliability of the fixed sound cavity 201 formed by the sound cavity forming member.

[0054] Based on the electronic device disclosed in any of the above embodiments, the present application also discloses a control method of the electronic device, which is applied to the electronic device disclosed in any of the above embodiments. Figure 3 The control method disclosed in the embodiment of the present application includes:

[0055] S1. Determine the working requirements of the electronic device; specifically, the working requirements of the electronic device include an image capture module and a sound playback mode, wherein, when entering the image capture mode, the electronic device needs to call the camera module, and correspondingly, when entering the sound playback mode, the electronic device needs to call the sound module.

[0056] S2. When the working requirement is the image shooting mode, the mounting seat is controlled to move in the direction away from the lens group so that the distance between the image sensor of the camera module and the lens group meets the preset zoom multiple. Specifically, as described above, the image sensor is mounted on the mounting seat, and the mounting seat can move relative to the lens group along the optical axis direction of the lens group. In this technology, when the mounting seat moves relative to the lens group and away from the lens group, the zoom multiple of the camera module can be increased to enhance the zoom capability of the camera module. Of course, the preset zoom multiple is a certain value within the zoom range of the camera module.

[0057] S3. When the working requirement is the sound playing mode, the mounting seat is controlled to move in the direction close to the lens group so that the volume of the closed area where the sound module in the variable sound cavity is located meets the preset sound volume. As described above, the mounting seat is movably and hermetically mounted on the variable sound cavity, and the sound module is also mounted in the variable sound cavity. Then, when the mounting seat moves relative to the inner wall of the variable sound cavity, the volume of the cavity in the variable sound cavity that provides acoustic effects for the sound module will also change accordingly. Based on this, when the working requirement is the sound playing mode, by making the mounting seat close to the lens group, the volume of the cavity in the variable sound cavity that provides acoustic effects for the sound module (that is, the volume of the closed area where the sound module in the variable sound cavity is located) can be increased to improve the acoustic performance of the sound module. Similarly, the volume value of the preset sound volume is less than or equal to the maximum volume value of the variable sound cavity.

[0058] It should be noted that, in this article, the terms "comprise", "include" or any other variant thereof are intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise one..." do not exclude the presence of other identical elements in the process, method, article or device including the element. In addition, it should be pointed out that the scope of the methods and devices in the embodiments of the present application is not limited to performing functions in the order shown or discussed, and may also include performing functions in a substantially simultaneous manner or in reverse order according to the functions involved, for example, the described method may be performed in an order different from that described, and various steps may also be added, omitted, or combined. In addition, the features described with reference to certain examples may be combined in other examples.

The above-mentioned specific implementation methods are merely illustrative and not restrictive.
