[0030] 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.

[0031] The term "and / or" in this article is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone.

[0032] The terms "first" and "second" in the description and claims of the embodiments of the present application are used to distinguish different objects rather than to describe a specific order of objects. For example, a first target object and a second target object are used to distinguish different target objects rather than to describe a specific order of target objects.

[0033] In the embodiments of the present application, words such as "exemplary" or "for example" are used to indicate examples, illustrations or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of the present application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present related concepts in a specific way.

[0034] In the description of the embodiments of the present application, unless otherwise specified, the meaning of "multiple" refers to two or more than two. For example, multiple processing units refer to two or more processing units; multiple systems refer to two or more systems.

[0035] Figure 1 A schematic diagram of the structure of a mobile phone provided for related technology, see Figure 1 . The positional relationship of each structure in the mobile phone is specified by the X-axis direction, the Y-axis direction and the Z-axis direction. Among them, the X-axis direction is the width direction of the mobile phone, the Y-axis direction is the length direction of the mobile phone, and the Z-axis direction is the thickness direction of the mobile phone. In the related art, the mobile phone 100 includes a rear shell (not shown in the figure), a battery 101, a middle frame 102, a mainboard 103, a limiter 104 and a display panel (not shown in the figure). Among them, the rear shell and the display panel are arranged relative to each other, the middle frame 102 is located between the rear shell and the display panel, and the middle frame 102, the rear shell and the display screen can form a receiving cavity. The battery 101, the mainboard 103 and the limiter 104 are arranged in the receiving cavity. The mainboard 103 is provided with a processor, a memory, a mobile phone sound cavity speaker and a camera. The mobile phone sound cavity speaker can play audio content under the control of the processor. For example, a ringtone can be played when the mobile phone calls, and music or songs can be played when the mobile phone needs to play multimedia content. In order to meet the user's shooting needs, a camera is also arranged on the mainboard 103. In order to firmly fix the camera, a limiter 104 is provided on the side of the mainboard 103 away from the back cover. The limiter 104 includes a mobile phone audio cavity speaker combination part and a camera limiter part. The mobile phone audio cavity speaker combination part is used to be fixedly combined with the mobile phone audio cavity speaker, so that the fixed limiter 104 can just use the camera limiter part to limit the position of the camera and play the role of fixing the camera.

[0036] However, in electronic products such as mobile phones, the camera position is often raised, and the area with the thickest thickness. The limiting part in the related art is often made of materials such as plastic. In order to ensure that the limiting part has a certain strength, the limiting part is often thicker, up to about 0.5mm. The limiting part of such thickness makes the already raised camera position more raised, which is not conducive to the thinness of electronic products. On the other hand, the plastic material of the mobile phone sound cavity speaker and the plastic material of the limiting part 104 are often connected by bonding or clamping technology. This assembly process takes up a lot of manpower, resulting in low assembly efficiency, which is not conducive to the mass production of mobile phones.

[0037] Based on the above problems, an embodiment of the present application provides an electronic device. The electronic device provided in the embodiment of the present application can be a mobile phone, a tablet computer, a personal digital assistant (PDA), a car computer, a smart wearable device, a smart home device, etc. The embodiment of the present application does not specifically limit the specific form of the above electronic devices. Figure 2 A schematic diagram of the structure of a mobile phone provided in an embodiment of the present application, see Figure 2 . For the convenience of explanation, the following description is made by taking a mobile phone as an example. In order to facilitate the clear description of the subsequent structural features and the positional relationship of the structural features, the positional relationship of the various structures in the mobile phone is specified in the X-axis direction, the Y-axis direction and the Z-axis direction. Among them, the X-axis direction is the width direction of the mobile phone, the Y-axis direction is the length direction of the mobile phone, and the Z-axis direction is the thickness direction of the mobile phone.

[0038] like Figure 2 As shown, the mobile phone 200 includes a battery 201, a middle frame 202, a rear shell (not shown in the figure), a display panel (not shown in the figure), a mainboard 203 and a mobile phone sound cavity speaker 204. The rear shell and the display panel are arranged relative to each other, and the middle frame 202 is located between the rear shell and the display panel. The middle frame 202, the rear shell and the display panel can enclose a housing cavity. The housing cavity is provided with a mobile phone sound cavity speaker 204, a mainboard 203, a battery 201 and a retaining wall for fixing the battery 201 and other structures. The mainboard 203 is provided with a processor and a memory. The memory is used to store computer program code. The computer program code includes computer instructions. The processor is used to call computer instructions to enable the mobile phone 200 to perform corresponding operations. The mobile phone sound cavity speaker 204 includes a mobile phone sound cavity speaker body 2041, and the shell of the mobile phone sound cavity speaker body 2041 can be made of metal. The specific parameters of the mobile phone sound cavity speaker body 2041 can be determined according to actual needs. A sound-generating device is arranged inside the mobile phone sound cavity speaker body 2041, which can play sound under the drive of an external electrical signal. Exemplarily, when a call comes in to the mobile phone, the processor is used to control the mobile phone audio cavity speaker 204 to play the incoming call ringtone.

[0039] The material of the rear cover may include, for example, opaque materials such as plastic, plain leather, and glass fiber; or may include translucent materials such as glass. The material of the rear cover is not limited in the embodiment of the present application.

[0040] The display panel includes, for example, a liquid crystal display (LCD) panel, an organic light emitting diode (OLED) display panel, and an LED display panel, etc. Among them, the LED display panel includes, for example, a Micro-LED display panel, a Mini-LED display panel, etc. The embodiment of the present application does not limit the type of the display panel.

[0041] The mobile phone sound cavity speaker body 2041 also includes a shell for encapsulating the sound-generating device to form a box body. The shell material can be metal. Since metal materials have the characteristic of high strength per unit volume, the mobile phone sound cavity speaker 204 provided in the embodiment of the present application is thinner while ensuring a certain structural strength, which is conducive to the thinning of electronic devices.

[0042] The mobile phone sound cavity speaker 204 also includes at least one extension part 2042 fixedly connected to the mobile phone sound cavity speaker body 2041, and the extension part 2042 can have corresponding functions and shapes according to actual needs. The material of the extension part 2042 is all metal material. The extension part 2042 of the metal material has a qualified structural strength and a thin thickness, which is conducive to the thinning of the electronic device. Several extension parts 2042 will be introduced as examples below. It should be noted that the extension part 2042 can be any structure that is connected to the mobile phone sound cavity speaker body 2041 and extends out. In actual implementation, the mobile phone sound cavity speaker 204 can include one extension part 2042, and can also include more than one extension part 2042, and various extension parts 2042 can be combined according to actual needs.

[0043] The mobile phone audio cavity speaker 204 may also include an electrical connection part for obtaining power and control signals from the mainboard 203. The electrical connection part may be any component that can realize electrical connection between the mobile phone audio cavity speaker 204 and the mainboard 203, so that the mobile phone audio cavity speaker 204 can obtain power and drive control signals from the mainboard 203. Exemplarily, the electrical connection part may be an FPC, the first end of the FPC is connected to the mobile phone audio cavity speaker body 2041, and the second end of the FPC includes an FPC terminal. An FPC plug-in part that matches the FPC terminal is provided on the mainboard 203. By inserting the FPC terminal into the FPC plug-in part, the electrical connection between the mobile phone audio cavity speaker 204 and the mainboard 203 can be realized.

[0044] Figure 3A schematic diagram of the structure of a mobile phone audio cavity speaker provided in an embodiment of the present application, see Figure 3 . The extension portion 2042 may include an FPC terminal pressing sub-portion 20421. The FPC terminal pressing sub-portion 20421 is connected to the mobile phone sound cavity speaker body 2041. After the mobile phone sound cavity speaker 204 is assembled, the FPC terminal pressing sub-portion 20421 is located on the side of the FPC terminal away from the main board 203, and is used to press the FPC terminal to prevent the FPC terminal inserted into the FPC plug-in portion from falling off. The shape of the FPC terminal pressing sub-portion 20421 can be determined according to actual needs. For example, the FPC terminal pressing sub-portion 20421 can completely cover the FPC terminal, or it can partially cover the FPC terminal.

[0045] Various electronic devices are also distributed on the mobile phone motherboard 203. When the electrical signal flows through the device, the device will emit electromagnetic waves, forming radiation interference. Radiated interference refers to the interference source coupling (interference) its signal to another electrical network through space. In the design of high-speed circuit boards and systems, high-frequency signal lines, pins of integrated circuits, various connectors, etc. may become radiation interference sources with antenna characteristics, which can emit electromagnetic waves and affect the normal operation of other systems or other subsystems in the system. Similarly, these devices may also be affected by electromagnetic interference signals emitted by devices in other areas or other electrical appliances.

[0046] In order to reduce the electromagnetic interference to the components on the mobile phone mainboard 203, and at the same time reduce the electromagnetic interference emitted by these components. Figure 3 , the extension portion 2042 may also include a device protection sub-portion 20422, and the device protection sub-portion 20422 is connected to the mobile phone sound cavity speaker body 2041. The mobile phone mainboard 203 includes a number of devices, including a first group of devices located around the mobile phone sound cavity speaker 204. After the mobile phone sound cavity speaker 204 is assembled, the device protection sub-portion 20422 is located on the side of the first group of devices away from the mainboard 203. The shape, area and position of the device protection sub-portion 20422 can be determined according to actual needs. Exemplarily, the device protection sub-portion 20422 can be a plate-like structure formed on the side of the first group of devices away from the mainboard 203, and in the direction perpendicular to the mainboard 203, the projection of the device protection sub-portion 20422 covers the first group of devices. Since the device protection sub-portion 20422 can block and reflect electromagnetic interference, it can reduce the electromagnetic interference received by the devices on the mobile phone mainboard 203, and at the same time reduce the electromagnetic interference emitted by these devices.

[0047] In order to further improve the stability of the FPC terminal pressing sub-section 20421 and the device protection sub-section 20422, the FPC terminal pressing sub-section 20421 may include an FPC terminal pressing sub-section body 204211 and a first fixing structure 204212, and the device protection sub-section 20422 may include a device protection sub-section body 204221 and a second fixing structure 204222. The first fixing structure 204212 is connected to the FPC terminal pressing sub-section body 204211, and is used to fix the FPC terminal pressing sub-section on the mobile phone middle frame 202. The second fixing structure 204222 is connected to the device protection sub-section body 204221, and is used to fix the device protection sub-section 20422 on the mobile phone middle frame 202. The embodiment of the utility model does not limit the specific structure of the first fixing structure 204212 and the second fixing structure 204222. For example, the first fixing structure 204212 or the second fixing structure 204222 may include at least one through hole through which a screw rod of a screw can pass, or at least one buckle structure that cooperates with the middle frame 202. The specific structure of the first fixing structure 204212 and the second fixing structure 204222 will be exemplified below. Figure 3 , the first fixing structure 204212 includes a first connecting piece 2042121, and the second fixing structure 204222 includes a second connecting piece 2042221. The FPC terminal pressing sub-section body 204211 and the device protection sub-section body 204221 are connected to each other, the first connecting piece 2042121 is connected to a side edge of the FPC terminal pressing sub-section body 204211 away from the device protection sub-section body 204221, and the second connecting piece 2042221 is connected to a side edge of the device protection sub-section body 204221 away from the FPC terminal pressing sub-section body 204211. A first through hole is provided on the first connecting piece 2042121, and a second through hole is provided on the second connecting piece 2042221. After the screw rod of the screw passes through the through hole, the screw can be screwed into the screw hole at the corresponding position on the middle frame 202, so that the FPC terminal pressing sub-section is firmly pressed on the FPC terminal to prevent the FPC terminal from falling off. The device protection sub-section 20422 can also be stably arranged above the device to shield electromagnetic interference. At the same time, the FPC terminal pressing sub-section, the device protection sub-section 20422 and the mobile phone audio cavity speaker 204 are integrated.

[0048] The first fixed structure 204212 and the second fixed structure 204222 can also serve as antenna grounding points, and the grounding end of the mobile phone antenna is connected to the antenna grounding point. The metal mobile phone audio cavity speaker 204 has good conductivity, which can make the mobile phone antenna have a good grounding effect. The specific connection method between the grounding end of the antenna and the first fixed structure 204212 or the second fixed structure 204222 can be determined according to actual needs. Exemplarily, the grounding end of the antenna can be abutted against the first fixed structure 204212 or the second fixed structure 204222, so that the grounding end of the antenna is electrically connected to the mobile phone audio cavity speaker 204 through the first fixed structure 204212 or the second fixed structure 204222, as well as the FPC terminal pressing sub-section body 204211 and the device protection sub-section body 204221, and forms an equipotential with the mobile phone audio cavity speaker 204, thereby realizing antenna grounding.

[0049] Figure 4 A schematic diagram of the structure of another mobile phone audio cavity speaker provided in the embodiment of the present application, see Figure 4 The extension portion 2042 may also include an antenna grounding sub-portion 20423. The grounding end of the antenna may be electrically connected to the mobile phone audio cavity speaker 204 through the antenna grounding sub-portion 20423 extending from the mobile phone audio cavity speaker 204, and form an equipotential with the mobile phone audio cavity speaker 204, thereby achieving antenna grounding. The specific connection method between the grounding end of the antenna and the antenna grounding sub-portion 20423 may be determined according to actual needs. For example, the grounding end of the antenna may be abutted against the antenna grounding sub-portion 20423 to achieve electrical connection between the two.

[0050] In order to further improve the stability of the antenna grounding sub-section 20423, the antenna grounding sub-section 20423 may include a third fixing structure 204231 for fixing the antenna grounding sub-section 20423 on the mobile phone middle frame 202. The embodiment of the utility model does not limit the specific structure of the third fixing structure 204231. For example, the third fixing structure 204231 may include at least one through hole through which a screw rod of a screw can pass, or at least one buckle structure that cooperates with the middle frame 202. The specific structure of the third fixing structure 204231 is exemplified below. Figure 4 The third fixing structure 204231 includes a third connecting member 2042311, and a third through hole is provided on the third connecting member 2042311. After the screw rod of the screw passes through the through hole, the screw can be screwed into the screw hole at the corresponding position on the middle frame 202, so that the antenna grounding sub-unit 20423 is firmly combined with the middle frame 202, which is conducive to the grounding end of the antenna being firmly in contact with the antenna grounding sub-unit 20423.

[0051] Figure 5A schematic diagram of the structure of another mobile phone audio cavity speaker provided in the embodiment of the present application, see Figure 5 The extension portion 2042 may also include a board-to-board (BTB) connection terminal pressing sub-portion 20424. Due to the area limitation of the main board 203 or based on the consideration of anti-electromagnetic interference, a sub-main board 203 is often added to the main board 203 inside the mobile phone. A board-to-board connection female socket can be provided on the mobile phone main board 203 and the mobile phone sub-main board 203, respectively. The board-to-board connection wire with board-to-board connection terminals at both ends is respectively inserted into the female sockets of the mobile phone main board 203 and the mobile phone sub-main board 203, and the electrical connection between the mobile phone main board 203 and the mobile phone sub-main board 203 is conducted. On one side of the mobile phone main board 203, the board-to-board connection female socket is often provided near the mobile phone sound cavity speaker 204. After the board-to-board connection terminal is inserted into the board-to-board connection female socket, in order to prevent the board-to-board connection terminal from falling off, a board-to-board connection terminal pressing sub-portion 20424 is also extended from the mobile phone sound cavity speaker 204. After the cell phone audio cavity speaker 204 is assembled, the board-to-board connection terminal pressing sub-portion 20424 is located on the side of the board-to-board connection terminal away from the main board 203. The embodiment of the utility model does not limit the shape of the board-to-board connection terminal pressing sub-portion 20424, and the shape of the board-to-board connection terminal pressing sub-portion 20424 can be determined according to actual needs. For example, the board-to-board connection terminal pressing sub-portion 20424 can completely cover the board-to-board connection terminal, or can partially cover the board-to-board connection terminal.

[0052] In order to further improve the stability of the board-to-board connection terminal pressing sub-section 20424, the board-to-board connection terminal pressing sub-section 20424 may include a board-to-board connection terminal pressing sub-section body and a fourth fixing structure, and the fourth fixing structure is used to fix the board-to-board connection terminal pressing sub-section 20424 on the mobile phone middle frame 202. The embodiment of the utility model does not limit the specific structure of the fourth fixing structure. For example, the fourth fixing structure may include at least one through hole through which the screw rod of the screw can pass, or at least one buckle structure that cooperates with the middle frame 202.

[0053] The extension portion 2042 may also include a camera limit sub-unit. The camera limit sub-unit is connected to the mobile phone audio cavity speaker body 2041, and is used to fix the camera and limit the position movement of the camera. The embodiment of the utility model does not limit the specific structure of the camera limit sub-unit, and it only needs to be able to fix the camera. The specific structure of a camera limit sub-unit will be exemplified below. Figure 6 A schematic diagram of the structure of another mobile phone audio cavity speaker provided in the embodiment of the present application, see Figure 6The camera limit sub-unit 20425 includes a camera limit sub-unit body 204251, and the camera limit sub-unit body 204251 is provided with a camera limit hole for mounting the camera lens, and the camera lens can be inserted into the limit hole, which is not only conducive to the camera limit sub-unit body 204251 being close to the camera, pressing the camera in the desired position to prevent the camera from shaking in the Z-axis direction, but also more conducive to suppressing the camera from moving significantly in the X-axis direction and the Y-axis direction. The camera limit sub-unit 20425 ensures the assembly accuracy of the camera and avoids the problem of the camera shifting or even falling off during use.

[0054] The camera position limiting sub-unit 20425 may include a camera position limiting sub-unit body 204251 and a fifth fixing structure 204252. The fifth fixing structure 204252 is connected to the camera position limiting sub-unit body 204251, and is used to fix the camera position limiting sub-unit 204255 on the mobile phone middle frame 202. The embodiment of the utility model is not limited to the specific structure of the fifth fixing structure 204252. For example, the fifth fixing structure 204252 may include at least one through hole through which a screw rod of a screw can pass, or at least one buckle structure that cooperates with the middle frame 202. The specific structure of the fifth fixing structure 204252 will be exemplified below. Continue to see Figure 6 The fifth fixing structure 204252 includes a fourth connecting member 2042521 connected to the first edge of the camera position limiting sub-unit body 204251, and a fourth through hole is provided on the fourth connecting member 2042521. The fifth fixing structure 204252 also includes a fifth connecting member 2042522 connected to the second edge of the camera position limiting sub-unit body 204251, and a fifth through hole is provided on the fifth connecting member 2042522. And a sixth connecting member 2042523 is arranged at the angle formed by the intersection of the third edge and the fourth edge of the camera position limiting sub-unit body 204251, and a sixth through hole is provided on the sixth connecting member 2042523. After the screw rod of the screw passes through the through hole, the screw can be screwed into the screw hole at the corresponding position on the middle frame 202, so that the camera is firmly pressed on the middle frame 202 by the camera position limiting sub-unit body 204251.
