[0028] The present application will be further described in detail below in conjunction with the accompanying drawings and examples. It is particularly noted that the following examples are only used to illustrate the present application and do not limit the scope of the present application. Similarly, the following examples are only some embodiments of the present application and not all embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0029] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0030] Please refer to Figure 1 , Figure 1 1 is a perspective diagram of an electronic device provided in an embodiment of the present application. The present application provides an electronic device 1000. Specifically, the electronic device 1000 can be any of various types of computer system devices that are mobile or portable and perform wireless communication ( Figure 1 (Only one form is shown exemplarily). Specifically, the electronic device 1000 can be a mobile phone or smart phone (e.g., an iPhone™-based or Android™-based phone), a portable gaming device (e.g., a Nintendo DS™, a PlayStation Portable™, a Gameboy Advance™, an iPhone™), a tablet, a laptop, a PDA, a portable internet device, a music player, a data storage device, other handheld devices, and headphones.

[0033] It should be noted that the terms "first," "second," and "third" in this application are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the technical features indicated. Therefore, a feature defined as "first," "second," or "third" may explicitly or implicitly include at least one of such features. In the description of this application, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0034] Please refer to Figures 2 to 5 , Figure 2 yes Figure 1 The cross-sectional view of the electronic device shown is along the AA direction. Figure 3 yes Figure 1 A schematic diagram of a portion of the structure of the electronic device shown, Figure 4 yes Figure 1 The three-dimensional schematic diagram of the electronic device middle frame, the first mainboard and the speaker is shown. Figure 5 yes Figure 4The three-dimensional schematic diagram of the middle frame and the first mainboard shown. The electronic device 1000 may include a middle frame 600, a display screen 500, a first mainboard 400, a second mainboard 300, a USB port 200 and a speaker 100. The middle frame 600 and the display screen 500 are connected and enclosed to form a housing 601, which can be used to set the first mainboard 400, the second mainboard 300, the speaker 100, the camera mechanism, the mainboard, the battery and other structural components to enable the electronic device 1000 to achieve corresponding functions. Among them, the speaker 100, the display screen 500, the camera mechanism and other structural components can be electrically connected to one or more of the first mainboard 400, the second mainboard 300, the battery, etc. through a flexible printed circuit 20 (FPC), so that they can obtain power from the battery and can execute corresponding instructions under the control of the first mainboard 400 or the second mainboard 300.

[0035] The middle frame 600 can be used to install various electronic components required for the electronic device 1000, and the middle frame 600 can be enclosed together with the display screen 500 to form an accommodation space 601. The accommodation space 601 can be used to install electronic components such as optical sensors to achieve functions such as fingerprint unlocking, automatic screen off, and self-adjustment of brightness. The accommodation space 601 can also be used to install electronic components such as speakers 100, flashlights, circuit boards, and batteries to achieve functions such as voice communication, audio playback, and lighting. Specifically, one end of the middle frame 600 may be provided with at least one fixing groove 601, and the speaker 100 corresponds to the fixing groove 601 one by one and is fixed in the fixing groove 601.

[0036] The display screen 500 can be used to provide an image display function for the electronic device 1000. When the user uses the shooting function of the electronic device 1000, the display screen 500 can present the imaging picture of the camera mechanism for the user to observe and operate.

[0037] The first motherboard 400 is an auxiliary circuit board, also known as a USB mini-board. Specifically, the first motherboard 400 is typically fixed to the edge of the middle frame 600 to connect structures such as the USB port 200 and the speaker 100. The second motherboard 300 is the main circuit board. The first motherboard 400 is electrically connected to the second motherboard 300, allowing the speaker 100, USB port 200, and other devices to execute corresponding instructions under the control of the second motherboard 300. The first motherboard 400 is fixed to the middle frame 600 and covers at least a portion of the fixing slot 601, so that the speaker 100 fixed in the fixing slot 601 can be electrically connected to the first motherboard 400.

[0038] In the related art, the USB port is connected to the first motherboard, and the USB port and the first motherboard are located at the edge of the middle frame. The electronic device usually includes a plurality of speakers, wherein two speakers are symmetrically arranged on opposite sides of the USB port (or the first motherboard). It can be understood that the two speakers adjacent to the first motherboard are far away from the second motherboard, so the cost of electrically connecting them to the second motherboard separately is high and the wiring is inconvenient, so the two speakers adjacent to the first motherboard usually transfer the signal to the second motherboard through the first motherboard. Since the two speakers adjacent to the first motherboard are symmetrically arranged with the first motherboard and need to be electrically connected to the first motherboard respectively, on the one hand, it is difficult for the two speakers to share the same design, that is, the two speakers need to use two sets of molds, which is costly; on the other hand, the two speakers are relatively similar in structure, and alignment errors are prone to occur, affecting the assembly efficiency of the production line. In view of this, it is necessary to provide a new speaker.

[0039] Please also refer to Figure 4 、 Figure 5 、 Figure 6 and Figure 7 , Figure 6 yes Figure 4 The stereoscopic diagram of the loudspeaker shown in FIG. Figure 7 yes Figure 6 An exploded schematic diagram of a speaker is shown. This embodiment of the present application provides a novel speaker 100, which may include, but is not limited to, a speaker body 10 and a flexible circuit board 20. The speaker body 10 may include a first fixing portion 101 and a second fixing portion 102 of identical structure. One end of the flexible circuit board 20 is connected to the first fixing portion 101 and / or the second fixing portion 102, and the other end is electrically connected to the first mainboard 400. Specifically, there is at least one first fixing portion 101 and at least one second fixing portion 102.

[0040] In this embodiment, the first fixing portion 101 and the second fixing portion 102 are symmetrically arranged along the center line L of the speaker body 10, making the speaker 100 structurally beautiful. In other embodiments, the first fixing portion 101 and the second fixing portion 102 can be located at any position of the speaker body 10, and are not specifically limited here.

[0041] Specifically, the speaker body 10 may include a first side 1011 (for example, the left side of the speaker body 10) and a second side 1012 (for example, the right side of the speaker body 10) arranged in opposite directions. The first fixing portion 101 may be located on the first side 1011 of the speaker body 10, and the second fixing portion 102 is located on the second side 1012 of the speaker body 10. The first fixing portion 101 and the second fixing portion 102 are symmetrical about the center line L of the speaker body 10.

[0042] Optionally, the first main board 400 may include a first end 401 (for example, the left end of the first main board 400) and a second end 402 (for example, the right end of the first main board 400) arranged opposite to each other. The speaker 100 may be located at the first end 401 of the first main board 400 and electrically connected to the first main board 400 through the flexible circuit board 20 on the second fixed portion 102, or it may be located at the second end 402 of the first main board 400 and electrically connected to the first main board 400 through the flexible circuit board 20 on the first fixed portion 101. It is understood that when the flexible circuit board 20 is located only on the first fixing portion 101, the speaker 100 can be fixed to the second end 402 of the first mainboard 400; when the flexible circuit board 20 is located only on the second fixing portion 102, the speaker 100 can be fixed to the first end 401 of the first mainboard 400; when the flexible circuit board 20 is located on both the first fixing portion 101 and the second fixing portion 102, the speaker 100 can be located at either the first end 401 or the second end 402 of the first mainboard 400. In other words, the speaker 100 does not need to be positioned differently on the first mainboard 400. In this way, regardless of whether the speaker 100 is located at the first end 401 or the second end 402 of the first mainboard 400, the structure of the speaker body 10 remains the same. This means that the speaker body 10 only requires one set of molds, which provides high versatility and significantly reduces mold making costs.

[0043] It is understood that when the flexible circuit board 20 is located on both the first fixing portion 101 and the second fixing portion 102, the speaker 100 can be located at either end of the first mainboard 400. This means that there is no need to distinguish between the first end 401 and the second end 402 of the first mainboard 400. This arrangement is understandably easier to install and more reliable, but one of the flexible circuit boards 20 is left idle, resulting in material waste. When the speaker 100 needs to be fixed to the first end 401 of the first mainboard 400, the flexible circuit board 20 can be located on the second fixing portion 102. This ensures accurate and reliable alignment of the speaker 100 while reducing waste of materials used for the flexible circuit board 20. Similarly, when the speaker 100 needs to be fixed to the second end 402 of the first mainboard 400, the flexible circuit board 20 can be located on the first fixing portion 101. This ensures accurate and reliable alignment of the speaker 100 while reducing waste of materials used for the flexible circuit board 20.

[0044] Please continue to refer to Figure 7Furthermore, one end of the flexible circuit board 20 can be detachably connected to the first fixing portion 101 and / or the second fixing portion 102. Specifically, when the flexible circuit board 20 is mounted on the first fixing portion 101, the speaker 100 can be located at the second end 402 of the first mainboard 400; when the flexible circuit board 20 is mounted on the second fixing portion 102, the speaker 100 can be located at the first end 401 of the first mainboard 400; and when the flexible circuit board 20 is located on both the first fixing portion 101 and the second fixing portion 102, the speaker 100 can be located at either the second end 402 or the first end 401 of the first mainboard 400. In other words, the speaker 100 can be flexibly adjusted to the first fixing portion 101 or the second fixing portion 102 according to its position on the first mainboard 400 to meet the required alignment of the speaker 100.

[0045] Please refer to Figure 8 Optionally, the speaker body 10 may be provided with slots 103 (specifically, first slots 103a and second slots 103b) located on the first fixing portion 101 and the second fixing portion 102, respectively. At least a portion of the flexible circuit board 20 is retained in the slots 103, thereby enabling a detachable connection between the flexible circuit board 20 and the first fixing portion 101 and / or the second fixing portion 102. In other words, the first fixing portion 101 may be provided with a first slot 103a, and the second fixing portion 102 may be provided with a second slot 103b. At least a portion of the flexible circuit board 20 is retained and connected to the first slot 103a, thereby enabling the speaker 100 to be positioned at the second end 402 of the first mainboard 400. Alternatively, the first fixing portion 101 may be provided with a first slot 103a, and the second fixing portion 102 may be provided with a second slot 103b. At least a portion of the flexible circuit board 20 is retained and connected to the second slot 103b, thereby enabling the speaker 100 to be positioned at the first end 401 of the first mainboard 400. Alternatively, a first slot 103a may be provided on the first fixing portion 101, and a second slot 103b may be provided on the second fixing portion 102. The flexible circuit board 20 is clamped and connected in the first slot 103a and the second slot 103b, so that the speaker 100 can be located at either end of the first mainboard 400.

[0046] As can be understood, when the speaker 100 is to be positioned at the first end 401 of the first mainboard 400, the flexible circuit board 20 can be mounted in the second slot 103b of the speaker 100; when the speaker 100 is to be positioned at the second end 402 of the first mainboard 400, the flexible circuit board 20 can be mounted in the first slot 103a of the speaker 100. In other words, the flexible circuit board 20 can be flexibly mounted in the first slot 103a and / or the second slot 103b, depending on the desired location of the speaker 100. This allows the structure of the speaker body 10 to be universal regardless of the speaker 100's location, while also ensuring electrical connection between the flexible circuit board 20 in the speaker 100 and the first mainboard 400. Furthermore, the first slot 103a and the second slot 103b protect the flexible circuit board 20 and constrain its position.

[0047] Furthermore, at least one first positioning structure 104 is provided in the slot 103, and a second positioning structure 21 corresponding to the first positioning structure 104 is provided on the flexible circuit board 20. The first positioning structure 104 is clamped in the corresponding second positioning structure 21. On the one hand, the flexible circuit board 20 is clamped and connected to the slot 103 of the first fixing part 101 and / or the second fixing part 102, ensuring the reliability of the electrical connection between one end of the flexible circuit board 20 and the first main board 400. On the other hand, it can improve the reliability of the connection between the flexible circuit board 20 and the slot 103, and prevent the flexible circuit board 20 from detaching from the slot 103.

[0048] Specifically, the first positioning structure 104 can be one of the positioning column and the positioning hole, and the second positioning structure 21 can be the other of the positioning column and the positioning hole. The positioning column is clamped and connected in the positioning hole, so that the first positioning structure 104 and the second positioning structure 21 are clamped and connected. On the one hand, the flexible circuit board 20 is accurately positioned in the card slot 103, ensuring the reliability of the electrical connection between one end of the flexible circuit board 20 and the first main board 400. On the other hand, it can improve the reliability of the connection between the flexible circuit board 20 and the card slot 103, and prevent the flexible circuit board 20 from detaching from the card slot 103.

[0049] Please continue to refer to Figure 8 , Figure 8 yes Figure 7A partial enlarged view of area B is shown. In one specific embodiment, the first positioning structure 104 is a positioning post 104a. Specifically, the inner wall of the first slot 103a has a first positioning structure 104 (specifically, a positioning post 104a), and the edge of the flexible circuit board 20 is provided with a second positioning structure 21 (specifically, a positioning hole 21a) corresponding to the first positioning structure 104. The first positioning structure 104 and the second positioning structure 21 are locked and connected. On the one hand, this ensures that the flexible circuit board 20 is accurately positioned in the slot 103, ensuring the reliability of the electrical connection between one end of the flexible circuit board 20 and the first mainboard 400. On the other hand, it improves the reliability of the connection between the flexible circuit board 20 and the slot 103 and prevents the flexible circuit board 20 from being separated from the slot 103. Similarly, the inner wall of the second slot 103b has a first positioning structure 104 (specifically, a positioning post), and the edge of the flexible circuit board 20 is provided with a second positioning structure 21 (specifically, a positioning hole) corresponding to the first positioning structure 104. The first positioning structure 104 can be locked and connected with the second positioning structure 21.

[0050] In one embodiment, the first positioning structure 104 is a positioning post. Specifically, the bottom wall of the first slot 103a is provided with a first positioning structure 104 (e.g., a positioning post), and the flexible circuit board 20 is provided with a second positioning structure 21 (e.g., a positioning hole) corresponding to the first positioning structure 104. The first positioning structure 104 and the second positioning structure 21 are locked and connected. On the one hand, this allows the flexible circuit board 20 to be accurately positioned in the slot 103, ensuring the reliability of the electrical connection between one end of the flexible circuit board 20 and the first mainboard 400. On the other hand, this improves the reliability of the connection between the flexible circuit board 20 and the slot 103 and prevents the flexible circuit board 20 from being separated from the slot 103. Similarly, the bottom wall of the second slot 103b is provided with a first positioning structure 104 (e.g., a positioning post), and the flexible circuit board 20 is provided with a second positioning structure 21 (e.g., a positioning hole) corresponding to the first positioning structure 104. The first positioning structure 104 can be locked and connected with the second positioning structure 21.

[0051] Please refer to Figure 9 and Figure 10 , Figure 9 yes Figure 7 The exploded diagram of the speaker 10 is a deformation diagram. Figure 9A partial enlarged view of area C is shown. In another embodiment, at least one first positioning structure 104 is provided on the first fixing portion 101 and the second fixing portion 102, and a second positioning structure 21 corresponding to the first positioning structure 104 is provided on the flexible circuit board 20. The first positioning structure 104 is retained in the corresponding second positioning structure 21. This not only allows the flexible circuit board 20 to be retained and connected to the first fixing portion 101 and / or the second fixing portion 102, ensuring the reliability of the electrical connection between one end of the flexible circuit board 20 and the first mainboard 400, but also improves the reliability of the connection between the flexible circuit board 20 and the first fixing portion 101 and / or the second fixing portion 102, preventing the flexible circuit board 20 from being detached from the first fixing portion 101 and / or the second fixing portion 102.

[0052] Specifically, the first positioning structure 104 can be one of the positioning column and the positioning hole, and the second positioning structure 21 can be the other of the positioning column and the positioning hole. The positioning column is clamped and connected in the positioning hole, so that the first positioning structure 104 and the second positioning structure 21 are clamped and connected. On the one hand, the flexible circuit board 20 is accurately positioned in the card slot 103, ensuring the reliability of the electrical connection between one end of the flexible circuit board 20 and the first main board 400. On the other hand, it can improve the reliability of the connection between the flexible circuit board 20 and the card slot 103, and prevent the flexible circuit board 20 from detaching from the card slot 103.

[0053] In a specific embodiment, the first fixing portion 101 has a first positioning structure 104, and the edge of the flexible circuit board 20 has a second positioning structure 21 corresponding to the first positioning structure 104. The first positioning structure 104 and the second positioning structure 21 are locked and connected. On the one hand, this allows the flexible circuit board 20 to be accurately positioned in the slot 103, ensuring the reliability of the electrical connection between one end of the flexible circuit board 20 and the first mainboard 400. On the other hand, it improves the reliability of the connection between the flexible circuit board 20 and the slot 103 and prevents the flexible circuit board 20 from being separated from the slot 103. Similarly, the second fixing portion 102 has a first positioning structure 104, and the edge of the flexible circuit board 20 has a second positioning structure 21 corresponding to the first positioning structure 104. The first positioning structure 104 can be locked and connected with the second positioning structure 21.

[0054] Please continue to refer to Figure 6 and Figure 7The speaker body 10 further includes a first fixing hole 105 and a second fixing hole 106 symmetrically arranged along the center line L. The speaker body 10 is respectively passed through the first fixing hole 105 and the second fixing hole 106 by fixing members (not shown) to secure the speaker body 10 to the electronic device 1000. It is understood that to ensure the universal connection between the speaker body 10 and the middle frame 600, that is, to ensure that the speaker 100 can be secured to both the first end 401 and the second end 402 of the first mainboard 400, the first fixing hole 105 and the second fixing hole 106 are symmetrically arranged about the center line L of the speaker 100.

[0055] Please refer to Figure 11 , Figure 11 yes Figure 7 Schematic diagram of an exploded view of the speaker body in the aforementioned speaker. Optionally, the speaker body 10 may include a first housing 11, a second housing 12, a sound unit 13, and a grounding unit 14 that are connected to each other in a covering manner. The first housing 11 and the second housing 12 are connected to each other in a covering manner and form a receiving chamber 110 for accommodating the sound unit 13.

[0056] The first shell 11 includes a main body 111 and a first fixing portion 101 and a second fixing portion 102 extending from both ends of the main body 111. The second shell 12 is arranged corresponding to the main body 111 of the first shell 11. The second shell 12 includes a plastic portion 121 and a vibration portion 122 embedded in the plastic portion 121, wherein the vibration portion 122 is a metal sheet. The sound unit 13 is fixed on the main body 111 and is provided with a gap with the vibration portion 122 of the second shell 12, so that the sound unit 13 and the vibration portion 122 are surrounded to form a front sound cavity (not shown). Specifically, the gap between the sound unit 13 and the vibration portion 122 is greater than or equal to 0.7 mm, so that the sound emitted by the sound unit 13 can produce effective vibration in the front sound cavity.

[0057] A through hole is provided at the position of the main body 111 corresponding to the sound unit 13. One end of the grounding unit 14 is electrically connected to the sound unit 13 through the through hole, and the other end is electrically connected to the vibration part 122 of the second shell 12, so that the sound unit 13 can be grounded, thereby improving the reliability of the sound unit 13.

[0058] The speaker 100 provided in the embodiment of the present application is symmetrically arranged along the center line L of the speaker body 10 by arranging the first fixing portion 101 and the second fixing portion 102, and the flexible circuit board 20 is located on the first fixing portion 101 and / or the second fixing portion 102. This ensures that the speaker 100 is effectively connected to the first main board 400, and the speaker body 10 only requires one set of molds, has strong versatility, and can greatly reduce the mold opening cost.

[0059] Please refer to Figure 4 、 Figure 5 、 Figure 12 and Figure 13 , Figure 12 yes Figure 5 The three-dimensional schematic diagram of the middle frame shown in FIG. Figure 13 yes Figure 12 A partial enlarged view of area D is shown. In this embodiment, the middle frame 600 includes at least one fixing slot 601, and of course it can also include two, three, or more. A speaker 100 is disposed in at least one fixing slot 601. Each fixing slot 601 includes a first ear slot 6011 and a second ear slot 6012 symmetrically arranged, wherein the shape of the first ear slot 6011 corresponds to the first fixing portion 101 or the second fixing portion 102. The first mainboard 400 is fixed to the middle frame 600, and the first mainboard 400 covers at least a portion of the first ear slot 6011 of each fixing slot 601 or is disposed adjacent to the first ear slot 6011 of each fixing slot 601. The speakers 100 correspond one-to-one to the fixing slots 601. One of the first fixing portion 101 and the second fixing portion 102 is fixed in the first ear slot 6011, and the other of the first fixing portion 101 and the second fixing portion 102 is fixed in the second ear slot 6012. In other words, the first fixing portion 101 or the second fixing portion 102 in each first ear slot 6011 is connected to the flexible circuit board 20. One end of the flexible circuit board 20 is electrically connected to the sound unit 13, and the other end is electrically connected to the first main board 400.

[0060] Furthermore, an anti-foolproofing column 6013 is provided in the second ear groove 6012, and an anti-foolproofing hole 107 corresponding to the anti-foolproofing column 6013 is provided on the first fixing part 101 and the second fixing part 102; the anti-foolproofing column 6013 is clamped in the corresponding anti-foolproofing hole 107, so that the speaker 100 can be fixed in the corresponding fixing groove 601, that is, when the flexible circuit board 20 is set in the first fixing part 101 or the second fixing part 102, the anti-foolproofing hole 107 of the first fixing part 101 or the second fixing part 102 is blocked and cannot cooperate with the anti-foolproofing column 6013.

[0061] When the flexible circuit board 20 of the speaker 100 is located on one of the first fixing part 101 or the second fixing part 102, specifically, taking the speaker 100 in which the flexible circuit board 20 is located on the first fixing part 101 as an example, when the speaker 100 is located in the fixing groove 601 on one side of the first end 401 of the first main board 400, the first fixing part 101 is accommodated in the second ear groove 6012 (that is, the flexible circuit board 20 is located in the second ear groove 6012), and the second fixing part 102 is accommodated in the first ear groove 6011. At this time, the flexible circuit board 20 is away from the first main board 400, that is, the speaker 100 cannot be installed in the corresponding fixing groove 601. Since an anti-foolproofing column 6013 is provided in the second ear groove 6012, the anti-foolproofing column 6013 is clamped in the anti-foolproofing hole 107 of the first fixing part 101, so that the flexible circuit board 20 in the first fixing part 101 cannot be clamped with the first fixing part 101 or the flexible circuit board 20 is kept away from the first fixing part 101, which makes it easy for production line workers to discover installation errors in time and improves the efficiency and reliability of the positioning of the speaker 100.

[0062] Of course, if the speaker 100 is directly positioned in the fixing slot 601 on the side of the second end 402 of the first mainboard 400, the first fixing portion 101 is received in the first ear slot 6011 (i.e., the flexible printed circuit board 20 is positioned in the first ear slot 6011), and the second fixing portion 102 is received in the second ear slot 6012. Since the second ear slot 6012 is provided with a foolproof post 6013, which is retained in the foolproof hole 107 of the second fixing portion 102, the foolproof post 6013 has no effect on the flexible printed circuit board 20, indicating that the speaker 100 is accurately aligned with the fixing slot 601.

[0063] Please refer to Figure 7 and Figure 8 In yet another embodiment, one end of the flexible circuit board 20 of the speaker 100 is detachably connected to the first fixing portion 101 and the second fixing portion 102. Specifically, because the flexible circuit board 20 is provided on both the first fixing portion 101 and the second fixing portion 102, regardless of whether the speaker 100 is located in the fixing slot 601 on the first end 401 side of the first mainboard 400 or in the fixing slot 601 on the second end 402 side of the first mainboard 400, at least one flexible circuit board 20 is electrically connected to the first mainboard 400. This eliminates the need to consider the alignment of the speaker 100 with the fixing slot 601, further improving installation efficiency.

[0064] Furthermore, an anti-foolproofing column 6013 is provided in the second ear groove 6012, and an anti-foolproofing hole 107 corresponding to the anti-foolproofing column 6013 is provided on the first fixing part 101 and the second fixing part 102; the anti-foolproofing column 6013 is clamped in the corresponding anti-foolproofing hole 107, so that the speaker 100 can be fixed in the corresponding fixing groove 601.

[0065] It can be understood that when the speaker 100 is fixed in a certain fixing groove 601, since the second ear groove 6012 is provided with an anti-fool column 6013, the anti-fool column 6013 is clamped in the anti-fool hole 107 of the first fixing part 101 or the second fixing part 102, so that the flexible circuit board 20 on the corresponding first fixing part 101 or the second fixing part 102 can be automatically detached, thereby reducing the consumption of auxiliary materials of the flexible circuit board 20, and further saving production costs on the basis of improving production efficiency.

[0066] In one specific embodiment, the middle frame 600 includes two fixing slots 601, one located on either side of the first mainboard 400. The electronic device 1000 includes two speakers 100, each of which is fixed in one of the fixing slots 601. Specifically, the middle frame 600 includes a first fixing slot 601 and a second fixing slot 601. The first fixing slot 601 is located at the first end 401 of the first mainboard 400, and the second fixing slot 601 is located at the second end 402 of the second mainboard 300. The two speakers 100 are respectively a first speaker 100 and a second speaker 100. The flexible printed circuit board 20 of the first speaker 100 is located at least on the second fixing portion 102, while the flexible printed circuit board 20 of the second speaker 100 is located at least on the first fixing portion 101. Therefore, the first speaker 100 is fixed in the first fixing slot 601, and the second speaker 100 is fixed in the second fixing slot 601.

[0067] Of course, the first and second speakers 100 can be customized as needed. Specifically, because one end of the flexible circuit board 20 is detachably connected to the first fixing portion 101 and / or the second fixing portion 102, when the flexible circuit board 20 is connected to the second fixing portion 102, the speaker 100 becomes the first speaker 100, and when the flexible circuit board 20 is connected to the first fixing portion 101, the speaker 100 becomes the second speaker 100. In other words, the user can adjust the position of the flexible circuit board 20 on the speaker body 10 as needed, allowing the speaker 100 to adapt to different positions.

[0068] In another embodiment, if the flexible circuit board 20 of the first speaker 100 is respectively located on the first fixing portion 101 and the second fixing portion 102 thereof, and the flexible circuit board 20 of the second speaker 100 is respectively located on the first fixing portion 101 and the second fixing portion 102 thereof, then the first speaker 100 can be interchanged with the first speaker 100, so that there is no need to consider the alignment of the speaker 100 and the fixing groove 601, thereby further improving the installation efficiency.

[0069] Optionally, the middle frame 600 may be provided with a first mounting hole 602 corresponding to the first fixing hole 105, and a second mounting hole 603 corresponding to the second fixing hole 106. The speaker body 10 is passed through the first fixing hole 105 and the corresponding first mounting hole 602, and the fixing member is passed through the second fixing hole 106 and the corresponding second mounting hole 603, so as to fix the speaker 100 to the middle frame 600. It can be understood that whether the speaker 100 is fixed to the first end 401 or the second end 402 of the first mainboard 400, the speaker body 10 and the middle frame 600 are adaptively connected.

[0070] The electronic device 1000 provided in the embodiment of the present application utilizes a speaker 100 with its first fixing portion 101 and second fixing portion 102 symmetrically positioned along the centerline L of the speaker body 10, with the flexible printed circuit board 20 positioned on the first fixing portion 101 and / or the second fixing portion 102. This ensures that the flexible printed circuit board 20 of the speaker 100 is effectively connected to the first mainboard 400, while requiring only one set of molds for the speaker body 100. This provides high versatility and significantly reduces mold making costs. Furthermore, by having the first mainboard 400 cover the first ear slot 6011 and the anti-mock post 6013 positioned in the second ear slot 6012, the speaker 100 can be accurately secured within the corresponding fixing slot 601, improving the efficiency and reliability of the speaker 100's alignment.
