Description

Technical Field

[0001] This disclosure relates to the field of electronic devices, and more particularly to a speaker assembly, a mid-frame assembly, and an electronic device. Background Technology

[0002] With the continuous development of technology, the screen design of electronic devices is gradually moving towards full-screen, and audio devices such as speakers in electronic devices will affect the development of the screen ratio of electronic devices. Utility Model Content

[0003] To overcome the problems existing in the related technologies, this disclosure provides a speaker assembly, a mid-frame assembly, and an electronic device.

[0004] According to a first aspect of this disclosure, a speaker assembly is provided, comprising: a speaker fixed to a mounting base; a bracket having a sound outlet channel within it, and an inlet and at least one outlet connected to the sound outlet channel on the outer surface of the bracket, the outlet of the speaker facing the outer surface of the bracket; and a drive mechanism fixed to the mounting base and drivenly connected to the bracket, the drive mechanism being used to drive the bracket to move between a first position and a second position, wherein in the first position, the inlet and outlet are opposite to each other, and in the second position, the outer surface of the bracket blocks at least part of the outlet. Thus, the movement of the bracket can be driven according to the speaker's usage state, i.e., the extension and retraction of the outlet can be controlled according to the speaker's usage state, so that the outlet capable of producing sound does not need to occupy a fixed position on the front of the electronic device, thereby improving the screen-to-body ratio of the electronic device, realizing a full-screen design, and thus not only enhancing the user's visual experience but also improving the aesthetic appeal of the electronic device. Furthermore, instead of moving the speaker by driving the bracket through a drive mechanism, the structure of the speaker assembly is simplified, which not only facilitates production and processing but also reduces the space occupied by the electronic equipment. At the same time, since the position of the speaker does not need to be changed, the reliability of the speaker can be effectively improved.

[0005] In some possible implementations, the bracket includes a body and a mounting portion. The sound outlet channel is disposed within the body, and the outer surface of the body is provided with the sound inlet and at least one sound outlet. The speaker is attached to the outer surface of the body, and the drive mechanism is driven and connected to the mounting portion. This avoids interference between the drive mechanism and the speaker, thereby further improving the reliability of the speaker assembly.

[0006] In some possible implementations, the outer surface of the body includes a first surface, a second surface, and a side surface connected to the first and second surfaces. The first and second surfaces are disposed opposite each other in the direction of movement of the bracket. The mounting portion is connected to the second surface. A portion of the side surface is recessed inward to form a groove structure. The sound inlet is located at the bottom of the groove structure, and the speaker is located within the groove structure. In the second position, the bottom of the groove structure blocks at least part of the sound outlet. This further reduces the overall volume of the speaker assembly.

[0007] In some possible implementations, the body has a plate-like structure, and the side surfaces include a first side surface and a second side surface disposed opposite to each other, and a third side surface and a fourth side surface connecting the first side surface and the second side surface and disposed opposite to each other. The groove structure is recessed from the first side surface toward the second side surface and extends through the third side surface and the fourth side surface. This facilitates the fixing of the speaker located within the groove structure to the mounting base, improving the ease of assembly of the speaker assembly, while preventing the fixing of the speaker from interfering with the movement of the bracket, thereby further improving the reliability of the speaker assembly.

[0008] In some possible implementations, at least one of the sound outlets is disposed in the region between the groove structure on the first side surface and the first surface. This has two advantages: First, placing at least one sound outlet close to the first surface facilitates its exposure within the electronic device, reducing the travel distance of the bracket. This not only further reduces the overall size of the speaker assembly but also prevents damage to the bracket due to excessive extension, thus improving the reliability of the speaker assembly. Second, by placing at least one sound outlet on the first side surface instead of the first surface itself, a concealed design can be achieved when the bracket moves to the second position. This not only improves the overall integrity of the electronic device's appearance and enhances its aesthetic appeal but also improves its sealing performance. Furthermore, it prevents impurities from clogging the sound outlets, further improving the speaker's sound quality.

[0009] In some possible implementations, the mounting portion includes: a support structure, a first end of which is connected to the second surface; and a connecting structure disposed at the second end of the support structure, with the connecting structure opposite to the second surface. This simplifies the structure of the mounting portion, making it easier to manufacture and process.

[0010] In some possible implementations, the drive mechanism includes: a motor fixed to the mounting base by a first fixing member; a lead screw assembly fixed to the mounting base by a second fixing member and driven to the output end of the motor; and a transmission member, the first end of which is fixed to the second surface, the second end of which is opposite to the connecting structure and connected to the lead screw assembly. The motor drives the transmission member to change position via the lead screw assembly, thereby driving the bracket to move between the first position and the second position. This simplifies the structure of the drive mechanism, facilitating production and processing, and further reduces the overall size of the speaker assembly.

[0011] In some possible implementations, the lead screw assembly includes: a lead screw driven to the motor; a first guide rod extending parallel to the extension direction of the lead screw; and a slider comprising a sliding portion and an extension portion connected together. The sliding portion is connected to a nut on the lead screw and slidably connected to the first guide rod, and the extension portion is connected to a second end of the transmission member. When the motor drives the lead screw to rotate, the sliding portion of the slider slides along the extension direction of the first guide rod under the action of the first guide rod, thereby driving the transmission member through the extension portion to move the bracket between a first position and a second position. This simplifies the structure of the lead screw assembly, making it easy to manufacture and process.

[0012] In some possible implementations, the transmission component includes an elastic element. Thus, when the bracket moves from the first position to the second position or from the second position to the first position, the elastic element facilitates the bracket's reset, improving the efficiency of the reset and thus enhancing the user experience.

[0013] In some possible implementations, the drive mechanism further includes a second guide rod, one end of which is fixed to the second surface, and the other end of which is fixed to the surface of the connecting structure facing the second surface. The elastic element is sleeved on the second guide rod, and the sliding element is sleeved on the second guide rod through a mounting hole. Thus, the second guide rod reduces the risk of deformation of the elastic element and prevents deformation from affecting the normal drive of the bracket movement, thereby further improving the reliability of the speaker assembly.

[0014] In some possible implementations, at least one of the sound outlets is provided with a dustproof mesh. This not only prevents impurities, moisture, oil, etc., from entering the sound outlet channel through the sound outlet, but also further improves the reliability of the speaker assembly and enhances the waterproof performance of the electronic equipment.

[0015] According to a second aspect of this disclosure, a mid-frame assembly is provided, comprising a mid-frame and a speaker assembly as described in the first aspect. The mid-frame includes a support portion and a frame surrounding the support portion, the support portion constituting a mounting base for the speaker assembly. This design, on the one hand, allows the support to be moved according to the speaker's usage state, i.e., controls the extension and retraction of the sound outlet according to the speaker's usage state. This ensures that the sound outlet does not occupy a fixed position on the front of the electronic device, thereby improving the screen-to-body ratio and achieving a full-screen design. This not only enhances the user's visual experience but also improves the aesthetic appeal of the electronic device. On the other hand, instead of driving the speaker to move, driving the support via a drive mechanism simplifies the structure of the speaker assembly, facilitating production and processing, and reducing the overall structural size of the speaker assembly, thus reducing its footprint within the electronic device's internal space. Furthermore, since the speaker's position does not need to be changed, the speaker's reliability is effectively improved.

[0016] In some possible implementations, the frame includes a first frame and a second frame connected together. The moving direction of the speaker assembly bracket is parallel to the first frame. The second frame has a through hole corresponding to the position of the bracket of the middle frame assembly. In a first position, the bracket extends out of the through hole, and at least one sound outlet on the bracket is exposed outside the second frame. In a second position, the outer surface of the bracket is flush with the outer surface of the second frame. Thus, when the speaker is needed, the sound outlet protrudes, resulting in more balanced sound quality and increased loudness, thereby enhancing the user experience. When the speaker is not needed, the sound outlet retracts into the frame, achieving a hidden design. This not only improves the integrity of the electronic device's appearance and enhances its aesthetic appeal but also improves its sealing. Furthermore, it prevents impurities from clogging the sound outlet, further improving the speaker's sound quality.

[0017] In some possible implementations, the first frame is a side frame, and the second frame is a top frame. That is, the bracket extends and retracts at the top frame, thus making it easier for the user to listen to audio when the speaker is used as a handset in scenarios such as making or receiving calls, improving ease of use.

[0018] In some possible implementations, at least one of the sound outlets in the first position faces the front of the mid-frame. This allows the user to hear the sound coming from the sound outlet while preventing sound leakage, thereby improving the privacy of electronic device calls.

[0019] In some possible implementations, the mid-frame assembly further includes a seal disposed between the inner circumferential surface of the through-hole and the bracket. This achieves a seal between the through-hole and the bracket, effectively improving the sealing performance of the electronic device, preventing impurities, moisture, etc., from entering the interior of the electronic device, and further enhancing the reliability of the electronic device.

[0020] According to a third aspect of this disclosure, an electronic device is provided, comprising a mid-frame assembly as described in the second aspect. Thus, when a speaker is needed, the sound outlet extends, enabling more balanced sound quality and increasing speaker loudness, thereby further enhancing the user experience. When the speaker is not needed, the sound outlet retracts into the frame, achieving a hidden design. This not only improves the overall integrity of the electronic device's appearance and enhances its aesthetic appeal, but also improves its sealing performance. Furthermore, it prevents impurities from clogging the sound outlet, further contributing to improved speaker sound quality.

[0021] The technical solutions provided by the embodiments of this disclosure may include the following beneficial effects:

[0022] The speaker assembly provided in this disclosure has a sound outlet channel provided in the bracket, and the outer surface of the bracket has a sound inlet and at least one sound outlet communicating with the sound outlet channel. The speaker is fixed to the mounting base and the sound outlet of the speaker faces the outer surface of the bracket. The drive mechanism is fixed to the mounting base and driven to the bracket. The drive mechanism drives the bracket to move between a first position and a second position. When the speaker is needed, the bracket is driven to move to the first position, and the sound inlet of the sound outlet channel is opposite to the sound outlet of the speaker so that the sound emitted by the speaker can be transmitted from the sound outlet of the sound outlet channel. When the speaker is not needed, the bracket is moved to the second position, at which time the outer surface of the bracket blocks at least part of the sound outlet.

[0023] In this way, the support can be moved according to the speaker's usage status, which in turn controls the extension and retraction of the sound outlet. This means the sound outlet doesn't need to occupy a fixed position on the front of the electronic device, thus increasing the screen-to-body ratio and enabling a full-screen design. This not only enhances the user's visual experience but also improves the device's overall aesthetic appeal. Furthermore, instead of driving the speaker itself, using a drive mechanism to move the support simplifies the speaker assembly structure, making production and processing easier and reducing the space it occupies within the electronic device. Simultaneously, since the speaker's position doesn't need to be changed, the speaker's reliability is also effectively improved.

[0024] It should be understood that the above general description and the following detailed description are exemplary and explanatory only, and are not intended to limit this disclosure. Attached Figure Description

Detailed Implementation

[0034] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0035] With the continuous development of technology, the screen design of electronic devices is gradually moving towards full-screen displays. However, audio components such as speakers can affect the screen-to-body ratio of electronic devices. For example, electronic devices often have speakers at the top for use as handsets during calls, and the speaker's outlet is usually located on the front of the device—a slit on the front serving as the speaker's outlet. This design, however, hinders the development of a high screen-to-body ratio and prevents the realization of a true full-screen design. In essence, a full-screen design refers to a screen with a 100% screen-to-body ratio.

[0036] Based on this, an exemplary embodiment of this disclosure provides an electronic device including a housing and a speaker assembly disposed on the housing. A sound outlet channel is provided on the frame of the housing, with the sound outlet of the sound outlet channel located on the side surface of the frame and the sound inlet of the sound outlet channel located inside the housing. The speaker assembly includes a mounting bracket, a speaker disposed on the mounting bracket, and a drive mechanism connected to the mounting bracket. When the speaker needs to emit sound, the drive mechanism drives the mounting bracket to move, thereby bringing the sound outlet of the speaker on the mounting bracket closer to the sound inlet of the sound outlet channel, so that the sound outlet of the speaker connects with the sound outlet channel, and sound is emitted through the sound outlet of the sound outlet channel. When the speaker is not needed, the drive mechanism drives the mounting bracket to move, thereby moving the speaker on the mounting bracket away from the sound outlet channel.

[0037] In the above configuration, since the speaker needs to be connected to various electrical components such as circuit boards and wiring, driving the speaker not only makes the overall structure of the speaker assembly more complex and occupies a larger space, but also makes it easy for the speaker to become loose and detached from the electrical components when moving the speaker, thus affecting the normal use of the speaker.

[0038] To address the above technical problems, another exemplary embodiment of this disclosure provides a speaker assembly. A sound outlet channel is provided within a bracket, and an inlet and at least one outlet connected to the sound outlet channel are provided on the outer surface of the bracket. The speaker is fixed to a mounting base with its outlet facing the outer surface of the bracket. A drive mechanism is fixed to the mounting base and driven to the bracket. The drive mechanism drives the bracket to move between a first position and a second position. When the speaker is needed, the bracket is driven to the first position, where the inlet of the sound outlet channel faces the outlet of the speaker, allowing sound emitted by the speaker to be transmitted from the outlet of the sound outlet channel. When the speaker is not needed, the bracket is moved to the second position, where the outer surface of the bracket blocks at least part of the outlet.

[0039] In this way, the support can be moved according to the speaker's usage status, which in turn controls the extension and retraction of the sound outlet. This means the sound outlet doesn't need to occupy a fixed position on the front of the electronic device, thus increasing the screen-to-body ratio and enabling a full-screen design. This not only enhances the user's visual experience but also improves the device's overall aesthetic appeal. Furthermore, instead of driving the speaker itself, using a drive mechanism to move the support simplifies the speaker assembly structure, making production and processing easier and reducing the space it occupies within the electronic device. Simultaneously, since the speaker's position doesn't need to be changed, the speaker's reliability is also effectively improved.

[0040] An exemplary embodiment of this disclosure provides a speaker assembly, such as Figure 1 , Figure 2 and Figure 3 As shown, the speaker assembly 13 includes a speaker 133, a bracket 131, and a driving mechanism. The speaker 133 is fixed to a mounting base. The mounting base may be, for example, the mid-frame of the electronic device 10. A sound outlet channel 132 is provided within the bracket 131, and a sound inlet 1321 and at least one sound outlet 1322 communicating with the sound outlet channel 132 are provided on the outer surface of the bracket 131, with the sound outlet 1331 of the speaker 133 facing the outer surface of the bracket 131. Exemplarily, only one sound outlet 1322 may be provided on the outer surface of the bracket 131, or multiple sound outlets may be provided on the outer surface of the bracket 131, such as 2, 3, 5, etc.

[0041] The drive mechanism is fixed to the mounting base and driven to the bracket 131. The drive mechanism is used to drive the bracket 131 to move between a first position and a second position. For example, the drive mechanism may be a lead screw assembly, connecting rod assembly, gear assembly, etc., which are driven and connected to the motor 134. There is no specific limitation on this, as long as it can drive the bracket 131 to move.

[0042] Combination Figure 3 and Figure 4 When the speaker 133 is needed, the drive bracket 131 moves to the first position, and the sound inlet 1321 of the sound outlet channel 132 faces the sound outlet 1331 of the speaker 133, so that the sound outlet 1331 of the speaker 133 is connected to the sound outlet channel 132, thereby allowing the sound emitted by the speaker 133 to be transmitted from the sound outlet 1322 of the sound outlet channel 132. Figure 5 When the speaker 133 is not needed, the drive mechanism drives the bracket 131 to move to the second position. At this time, the outer surface of the bracket 131 blocks at least part of the sound outlet 1331 to reduce the overall volume of the speaker assembly 13.

[0043] For example, when the bracket 131 is in the second position, the outer surface of the bracket 131 can partially block the sound outlet 1331, or it can completely block the entire sound outlet 1331. For example, the moving distance of the bracket 131 can be determined according to actual needs, such as in combination with... Figure 4 When the speaker assembly 13 is installed in the electronic device 10, the distance the bracket 131 moves from the second position to the first position is sufficient to expose the sound outlet 1322 of the sound outlet channel 132 outside the electronic device 10. Figure 6 The distance that bracket 131 moves from the first position to the second position is sufficient to allow bracket 131 to retract into electronic device 10 while maintaining the integrity of the outer surface of electronic device 10. The area of ​​the outer surface of bracket 131 that blocks the air outlet depends on the moving distance of bracket 131.

[0044] This design allows the support 131 to move according to the usage status of the speaker 133, which means controlling the extension and retraction of the sound outlet 1322 according to the usage status of the speaker 133. This ensures that the sound outlet 1322 does not need to occupy a fixed position on the front of the electronic device 10, thereby improving the screen ratio of the electronic device 10 and achieving a full-screen design. This not only enhances the user's visual experience but also improves the appearance and sophistication of the electronic device 10.

[0045] On the other hand, instead of moving the speaker 133, moving the bracket 131 via a drive mechanism simplifies the structure of the speaker assembly 13, making it easier to manufacture and process, reducing the overall size of the speaker assembly 13, and minimizing its impact on the internal space of the electronic device 10. Furthermore, since the position of the speaker 133 does not need to be changed, the reliability of the speaker 133 is effectively improved.

[0046] like Figure 1 and Figure 2As shown, in one embodiment, the bracket 131 includes a connected body 1311 and a mounting portion. A sound outlet channel 132 is disposed within the body 1311, and an inlet 1321 and at least one outlet 1322 are provided on the outer surface of the body 1311. The speaker 133 is attached to the outer surface of the body 1311. This arrangement facilitates communication between the outlet 1331 of the speaker 133 and the inlet 1321 on the outer surface of the body 1311. Furthermore, by shortening the distance between the speaker 133 and the outer surface of the body 1311, the sealing of the sound outlet channel 132 is improved, thereby enhancing the sound quality of the speaker 133. A drive mechanism is connected to the mounting portion. This configuration avoids interference between the drive mechanism and the speaker 133, further improving the reliability of the speaker assembly 13.

[0047] like Figure 1 , Figure 3 and Figure 5 As shown, in one embodiment, the outer surface of the body 1311 includes a first surface 1316, a second surface, and a side surface connected to the first surface 1316 and the second surface. The first surface 1316 and the second surface are disposed opposite to each other in the moving direction of the bracket 131, and the mounting part is connected to the second surface.

[0048] A portion of the side surface is recessed inward to form a groove structure 1314. The sound inlet 1321 is located at the bottom of the groove structure 1314, and the speaker 133 is located within the groove structure 1314, with its sound outlet 1331 facing the bottom of the groove structure 1314. In the direction of movement of the support 131, the width of the groove structure 1314 is greater than the length of the speaker 133, providing space for the support 131 to move between a first position and a second position. When the support 131 moves to the second position, the bottom of the groove structure 1314 blocks at least part of the sound outlet 1331. This design further reduces the overall volume of the speaker assembly 13.

[0049] like Figure 1 and Figure 2 As shown, in one embodiment, the body 1311 has a plate-like structure. Its side surfaces include a first side surface 1315 and a second side surface disposed opposite to each other, and a third side surface and a fourth side surface connecting the first side surface 1315 and the second side surface and disposed opposite to each other. A groove structure 1314 is recessed from the first side surface 1315 towards the second side surface and extends through the third and fourth side surfaces. This arrangement facilitates the fixing of the speaker 133, located within the groove structure 1314, to the mounting base, improving the assembly convenience of the speaker assembly 13. Simultaneously, it avoids interference between the fixing of the speaker 133 and the movement of the bracket 131, thereby further improving the reliability of the speaker assembly 13.

[0050] like Figure 1 and Figure 4 As shown, in one embodiment, at least one sound outlet 1322 is disposed in the area between the groove structure 1314 and the first surface 1316 of the first side surface 1315. This design, on the one hand, places at least one sound outlet 1322 close to the first surface 1316, making it easier for the sound outlet 1322 to be exposed to the electronic device 10. This helps to shorten the moving distance of the bracket 131, thereby not only further reducing the overall volume of the speaker assembly 13, but also preventing damage to the bracket 131 caused by excessive extension, further improving the reliability of the speaker assembly 13.

[0051] On the other hand, by placing at least one sound outlet 1322 on the first side surface 1315 instead of on the first surface 1316, the sound outlets 1322 can be hidden when the bracket 131 moves to the second position. This not only improves the overall integrity of the electronic device 10's appearance and enhances its aesthetic appeal, but also improves its sealing performance. Furthermore, it prevents impurities from clogging the sound outlets 1322, further improving the sound quality of the speaker 133.

[0052] like Figure 1 As shown, in one embodiment, a plurality of sound outlets 1322 are provided on the outer surface of the bracket 131. Along a direction perpendicular to the moving direction of the bracket 131, the plurality of sound outlets 1322 are spaced apart in the area between the groove structure 1314 and the first surface 1316 of the first side surface 1315. This reduces the area of ​​the region between the groove structure 1314 and the first surface 1316 of the first side surface 1315, thereby further reducing the volume of the bracket 131. For example, in this embodiment, the length of the first side surface 1315 of the body 1311 in the moving direction of the bracket 131 can be designed to be less than 5 mm, the length of the first side surface 1315 of the body 1311 in the moving direction perpendicular to the moving direction of the bracket 131 can be designed to be less than 5 mm, and the length of the first surface 1316 of the body 1311 in the direction perpendicular to the first side surface 1315 can be designed to be less than 3 mm.

[0053] like Figure 1 As shown, in one embodiment, the mounting portion includes a support structure 1313 and a connecting structure 1312. A first end of the support structure 1313 is connected to a second surface, and the connecting structure 1312 is disposed at a second end of the support structure 1313, with the connecting structure 1312 facing the second surface. This simplifies the structure of the mounting portion, making it easier to manufacture and process.

[0054] like Figure 1 and Figure 2As shown, in one embodiment, the drive mechanism includes a motor 134, a lead screw assembly, and a transmission component. The motor 134 is fixed to the mounting base via a first fixing member 14. Exemplarily, the first fixing member 14 may be a frame, a fixing plate, or other structural form, and can be fixed to the mounting base by means of screws, adhesive bonding, welding, etc. The lead screw assembly is fixed to the mounting base via a second fixing member 15 and is drivenly connected to the output end of the motor 134. Exemplarily, the second fixing member 15 may also be a frame, a fixing plate, or other structural form, and can be fixed to the mounting base by means of screws, adhesive bonding, welding, etc.

[0055] The first end of the transmission component is fixed to the second surface, and the second end of the transmission component is opposite to the connecting structure 1312 and connected to the lead screw assembly. The motor 134 drives the transmission component to change through the lead screw assembly, thereby driving the bracket 131 to move between the first position and the second position. Exemplarily, the lead screw assembly drives the transmission component to change; this change can be movement or deformation. For example, the transmission component can be a rod connected to the mounting portion or a spring connected to the mounting portion. When the transmission component is a rod, the lead screw assembly drives the rod to move, thereby driving the bracket 131 to move. When the transmission component is a spring, the lead screw assembly drives the spring to deform, thereby driving the bracket 131 to move. This embodiment does not specifically limit the specifics.

[0056] This configuration simplifies the structure of the drive mechanism, making it easier to manufacture and process, while also helping to further reduce the overall size of the speaker assembly 13.

[0057] like Figure 1 and Figure 2 As shown, in one embodiment, the lead screw assembly includes a lead screw 135, a first guide rod 136, and a slider 137. The lead screw 135 is driven and connected to a motor 134, and the extension direction of the first guide rod 136 is parallel to the extension direction of the lead screw 135. The slider 137 includes a sliding portion 1371 and an extension portion 1372 connected together. The sliding portion 1371 is connected to a nut on the lead screw 135 and slidably connected to the first guide rod 136, and the extension portion 1372 is connected to the second end of the transmission member. When the motor 134 drives the lead screw 135 to rotate, the sliding portion 1371 of the slider 137 slides along the extension direction of the first guide rod 136 under the action of the first guide rod 136, and then drives the transmission member through the extension portion 1372 to move the bracket 131 between a first position and a second position. This makes the structure of the lead screw assembly simple and easy to manufacture and process.

[0058] like Figure 1As shown, in one embodiment, the transmission component includes an elastic element 138. When the motor 134 drives the lead screw 135 to rotate, the sliding element 137 causes the elastic element 138 to deform, thereby moving the bracket 131 between a first position and a second position. This design facilitates the return of the bracket 131 to its original position under the action of the elastic element 138 when the bracket 131 moves from the first position to the second position or from the second position to the first position, improving the efficiency of the bracket 131's return and thus enhancing the user experience.

[0059] like Figure 5 As shown, in one embodiment, the driving mechanism further includes a second guide rod 139. One end of the second guide rod 139 is fixed to the second surface, and the other end is fixed to the surface of the connecting structure 1312 facing the second surface. An elastic member 138 is sleeved on the second guide rod 139, and the extension 1372 of the sliding member 137 is sleeved on the second guide rod 139 through a mounting hole. With this arrangement, the risk of deformation of the elastic member 138 under the action of the second guide rod 139 is reduced, and the normal driving of the bracket 131 movement is avoided due to the deformation of the elastic member 138, thereby further improving the reliability of the speaker assembly 13.

[0060] In one embodiment, at least one sound outlet 1322 is provided with a dustproof mesh to provide waterproof and dustproof protection for the sound outlet 1322. In this way, impurities, moisture, oil stains and other contaminants can be prevented from entering the sound outlet channel 132 through the sound outlet 1322, thereby further improving the reliability of the speaker assembly 13 and helping to improve the waterproof performance of the electronic device 10.

[0061] For example, the dust filter can be detachably attached to the sound outlet 1322 by means of adhesive or other means, which makes it easy to install and remove the dust filter, thereby facilitating the user to replace the dust filter and further improving the user experience.

[0062] like Figure 1 , Figure 2 and Figure 3 As shown, an exemplary embodiment of this disclosure provides a mid-frame assembly, which includes a mid-frame and a speaker assembly 13 as described above. The speaker assembly 13 includes a speaker 133, a bracket 131, and a drive mechanism. The speaker 133 is fixed to a mounting base. The mid-frame includes a support portion and a frame surrounding the support portion, the support portion constituting the mounting base of the speaker assembly 13. That is, the speaker 133 can be fixed to the support portion by a fixing structure 16, which can be, for example, a fixing shell, a fixing plate, etc., and is not specifically limited here.

[0063] The bracket 131 has a sound outlet channel 132. The outer surface of the bracket 131 has a sound inlet 1321 and at least one sound outlet 1322 communicating with the sound outlet channel 132. The sound outlet 1331 of the speaker 133 faces the outer surface of the bracket 131. A drive mechanism is fixed to the mounting base and driven by the bracket 131. For example, the drive mechanism can be fixed to the support by screws, adhesive, welding, etc. The drive mechanism is used to drive the bracket 131 to move between a first position and a second position.

[0064] Combination Figure 3 and Figure 4 When the speaker 133 is needed, the drive bracket 131 moves to the first position, and the sound inlet 1321 of the sound outlet channel 132 faces the sound outlet 1331 of the speaker 133, so that the sound outlet 1331 of the speaker 133 is connected to the sound outlet channel 132, thereby allowing the sound emitted by the speaker 133 to be transmitted from the sound outlet 1322 of the sound outlet channel 132. Figure 5 and Figure 6 When the speaker 133 is not needed, the drive mechanism drives the bracket 131 to move to the second position. At this time, the outer surface of the bracket 131 blocks at least part of the sound outlet 1331 to reduce the overall volume of the speaker assembly 13.

[0065] This design allows the support 131 to move according to the usage status of the speaker 133, which means controlling the extension and retraction of the sound outlet 1322 according to the usage status of the speaker 133. This ensures that the sound outlet 1322 does not need to occupy a fixed position on the front of the electronic device 10, thereby improving the screen ratio of the electronic device 10 and achieving a full-screen design. This not only enhances the user's visual experience but also improves the appearance and sophistication of the electronic device 10.

[0066] On the other hand, instead of moving the speaker 133, moving the bracket 131 via a drive mechanism simplifies the structure of the speaker assembly 13, making it easier to manufacture and process, reducing the overall size of the speaker assembly 13, and minimizing its impact on the internal space of the electronic device 10. Furthermore, since the position of the speaker 133 does not need to be changed, the reliability of the speaker 133 is effectively improved.

[0067] like Figure 4 As shown, in one embodiment, the frame includes a first frame and a second frame connected together. The moving direction of the bracket 131 of the speaker assembly 13 is parallel to the first frame, and the second frame has a through hole corresponding to the position of the bracket 131 of the middle frame assembly. Combined with... Figure 3 and Figure 4When the speaker 133 is needed, the drive mechanism drives the bracket 131 to move to a first position, causing the bracket 131 to extend from the through hole, so that at least one sound outlet 1322 on the bracket 131 is exposed outside the second frame, thereby allowing the sound emitted by the speaker 133 to be transmitted from the sound outlet 1322. Figure 5 and Figure 6 When the speaker 133 is not needed, the drive mechanism drives the bracket 131 to move to the second position, and the outer surface of the bracket 131 is flush with the outer surface of the second frame, thereby achieving the hidden design of the sound outlet 1322.

[0068] This design allows the sound outlet 1322 to extend when the speaker 133 is needed, resulting in a more balanced sound quality and increased loudness, thus enhancing the user experience. When the speaker 133 is not in use, the sound outlet 1322 retracts into the frame, achieving a hidden design. This not only improves the overall appearance of the electronic device 10 and enhances its aesthetic appeal, but also improves its sealing. Furthermore, it prevents impurities from clogging the sound outlet 1322, further contributing to improved sound quality.

[0069] like Figure 4 and Figure 6 As shown, in one embodiment, the first frame is the side frame 11, and the second frame is the top frame 12. That is, the bracket 131 extends and retracts at the top frame 12, so that when the speaker 133 is used as a handset in scenarios such as making or receiving calls, it is convenient for the user to listen to audio, thus improving the ease of use.

[0070] like Figure 3 and Figure 4 As shown, in one embodiment, when the bracket 131 is in the first position, at least one sound outlet 1322 faces the direction of the front of the mid-frame. It is understood that the front of the mid-frame refers to the side of the mid-frame used to mount the screen assembly 17. By oriented at least one sound outlet 1322 towards the front of the mid-frame, it is easier for the user to hear the sound emitted from the sound outlet 1322 while preventing sound leakage, thereby improving the privacy of calls made by the electronic device 10.

[0071] In one embodiment, the mid-frame assembly further includes a seal disposed between the inner circumferential surface of the through hole and the bracket 131. Exemplarily, the seal may be a silicone sealing ring, a rubber sealing ring, or the like. This achieves a seal between the through hole and the bracket 131, effectively improving the sealing performance of the electronic device 10, preventing impurities, moisture, etc., from entering the interior of the electronic device 10, and further enhancing the reliability of the electronic device 10.

[0072] An exemplary embodiment of this disclosure provides an electronic device, which may be a mobile device with communication functions such as a mobile phone, tablet computer, laptop computer, handheld computer, in-vehicle electronic device, wearable device, ultra-mobile personal computer (UMPC), netbook, or personal digital assistant (PDA), or a non-mobile device with communication functions such as a personal computer (PC) or television (TV).

[0073] like Figure 4 As shown, the electronic device 10 includes the mid-frame assembly as described above. Figure 1 , Figure 2 and Figure 3 As shown, the mid-frame assembly includes a mid-frame and the speaker assembly 13 as described above. The speaker assembly 13 includes a speaker 133, a bracket 131, and a drive mechanism. The speaker 133 is fixed to the mounting base. The mid-frame includes a support portion and a frame surrounding the support portion, the support portion constituting the mounting base of the speaker assembly 13. That is, the speaker 133 can be fixed to the support portion by a fixing structure 16, which can be, for example, a fixing shell, a fixing plate, etc., and is not specifically limited here.

[0074] The bracket 131 has a sound outlet channel 132. The outer surface of the bracket 131 has a sound inlet 1321 and at least one sound outlet 1322 communicating with the sound outlet channel 132. The sound outlet 1331 of the speaker 133 faces the outer surface of the bracket 131. A drive mechanism is fixed to the mounting base and driven by the bracket 131. For example, the drive mechanism can be fixed to the support by screws, adhesive, welding, etc. The drive mechanism is used to drive the bracket 131 to move between a first position and a second position.

[0075] Combination Figure 3 and Figure 4 When the speaker 133 is needed, the drive bracket 131 moves to the first position, and the sound inlet 1321 of the sound outlet channel 132 faces the sound outlet 1331 of the speaker 133, so that the sound outlet 1331 of the speaker 133 is connected to the sound outlet channel 132, thereby allowing the sound emitted by the speaker 133 to be transmitted from the sound outlet 1322 of the sound outlet channel 132. Figure 5 and Figure 6 When the speaker 133 is not needed, the drive mechanism drives the bracket 131 to move to the second position. At this time, the outer surface of the bracket 131 blocks at least part of the sound outlet 1331 to reduce the overall volume of the speaker assembly 13.

[0076] This design allows the support 131 to move according to the usage status of the speaker 133, which means controlling the extension and retraction of the sound outlet 1322 according to the usage status of the speaker 133. This ensures that the sound outlet 1322 does not need to occupy a fixed position on the front of the electronic device 10, thereby improving the screen ratio of the electronic device 10 and achieving a full-screen design. This not only enhances the user's visual experience but also improves the appearance and sophistication of the electronic device 10.

[0077] On the other hand, instead of moving the speaker 133, moving the bracket 131 via a drive mechanism simplifies the structure of the speaker assembly 13, making it easier to manufacture and process, reducing the overall size of the speaker assembly 13, and minimizing its impact on the internal space of the electronic device 10. Furthermore, since the position of the speaker 133 does not need to be changed, the reliability of the speaker 133 is effectively improved.

[0078] For example, in this embodiment, the usage state of the speaker 133 can be triggered according to the usage state of the electronic device 10, thereby controlling the extension and retraction of the bracket 131 according to the usage state of the speaker 133. For example, when the electronic device 10 enters a handheld call state, the speaker 133 is triggered to be used as a handset, at which time the motor 134 controls the extension of the sound outlet 1322 on the bracket 131. When the electronic device 10 is in a call hang-up state, the bracket 131 is controlled to return to the second position within a first preset duration. The first preset duration is less than or equal to 0.5s. Alternatively, when the electronic device 10 is in an external playback scenario such as call playback or audio playback, the motor 134 controls the extension of the sound outlet 1322 on the bracket 131. When the external playback scenario ends (e.g., exiting audio software), the bracket 131 is controlled to return to the second position within a second preset duration. The second preset duration is less than or equal to 50ms.

[0079] The electronic device 10 can also have an anti-accidental touch mode. When the electronic device 10 enters handheld call mode and its screen is off, and after a pressure sensor detects that the electronic device 10 has been in contact with the ear for a third preset duration, the sound outlet 1322 on the control bracket 131 will extend. The third preset duration is greater than or equal to 0.3 seconds. This prevents the user from accidentally extending the bracket 131, further improving the user experience.

This application is intended to cover any variations, uses, or adaptations of this disclosure that follow the general principles of this disclosure and include common knowledge or customary techniques in the art not disclosed herein.
