Description

electronic devices

[0001] This application claims priority to Chinese Patent Application No. 202510122789.6, filed with the China National Intellectual Property Administration on January 24, 2025, entitled "Electronic Device", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of terminal electronic devices, and in particular to an electronic device. Background Technology

[0003] Current electronic devices are relatively mature in development. They typically have sound outlets and channels in the middle frame so that the internal sound-producing units can emit sound to the outside environment through these channels and outlets. However, using the middle frame to form the sound outlets and channels requires the sound-producing units to be placed close to the edge of the middle frame. This relatively fixed placement of the sound-producing units is not conducive to the flexible layout of internal components in electronic devices. Summary of the Invention

[0004] This application provides an electronic device with a more flexible arrangement of sound-generating units.

[0005] This application provides an electronic device. The electronic device includes a first middle frame, a first cover plate, a first display screen, and a first sound-emitting unit. The first cover plate is fixedly connected to the first middle frame and encloses an internal space with the first middle frame. The first sound-emitting unit is installed in the internal space. The first display screen is fixedly connected to the side of the first middle frame facing away from the first cover plate. The first cover plate has a first sound outlet, and the first sound-emitting unit emits sound through the first sound outlet.

[0006] Understandably, compared to typical electronic devices where the sound outlet is located on the middle frame, requiring the sound-emitting unit to be positioned close to the edge of the middle frame, resulting in a relatively fixed position for the sound-emitting unit and hindering flexible layout of internal components, this embodiment places the first sound outlet on the first cover plate. This allows for more flexible placement of the first sound-emitting unit, adapting to different component layouts within the electronic device.

[0007] In one possible implementation, the electronic device further includes a second middle frame and a folding mechanism. The folding mechanism connects the first middle frame and the second middle frame and is capable of movement so that the first middle frame and the second middle frame can be folded relative to each other to a closed state or unfolded relative to each other to an open state. The first display screen is fixedly connected to the first middle frame and the second middle frame. When the electronic device is in the closed state, the first display screen is located between the first middle frame and the second middle frame.

[0008] It is understood that in this embodiment, the first sound outlet is located on the first cover. Thus, when the electronic device is closed, the first sound outlet is not blocked by the second housing, and it can be exposed to the external environment. This allows the user to make voice calls even when the electronic device is closed, resulting in a better user experience.

[0009] In one possible implementation, the electronic device further includes a second sound-emitting unit installed in the internal space. The first middle frame is provided with a second sound outlet, and the second sound-emitting unit emits sound through the second sound outlet. The orientation of the second sound outlet is different from that of the first sound outlet.

[0010] It is understood that the electronic device in this embodiment also includes a second audio output port, which is located in the first middle frame. Thus, when the electronic device is in the open state, the user can make voice calls through the second audio output port; when the electronic device is in the closed state, the user can make calls through the first audio output port. In other words, regardless of the state of the electronic device, the user can use either the first or second audio output port to make voice calls, resulting in a better user experience.

[0011] In one possible implementation, when the electronic device is in a closed state, the first sound unit acts as a receiver, and when the electronic device is in an open state, the second sound unit acts as a receiver.

[0012] Understandably, compared to typical electronic devices that only have an inner screen earpiece slit (i.e., the second sound outlet in this embodiment), users need to keep the electronic device in the open state to make voice calls. This means that when the electronic device is in the closed state, users cannot answer voice calls and must manually switch the device from the closed to the open state to make a voice call. This process is cumbersome and provides a poor user experience. In contrast, the electronic device in this embodiment includes a first sound unit and a second sound unit. When the electronic device is in the open state, the user can make voice calls through the second sound outlet; when the electronic device is in the closed state, the user can make calls through the first sound outlet. In other words, regardless of the state of the electronic device, the user can use either the first or second sound outlet to make a voice call, resulting in a better user experience.

[0013] In one possible implementation, the first sound outlet is positioned closer to the folding mechanism than the second sound outlet.

[0014] In this way, when the electronic device is playing music, the distance between the first and second sound outlets is relatively large, which allows the electronic device to achieve a better stereo sound effect and a better user experience.

[0015] In one possible implementation, the electronic device further includes a third sound outlet, which is formed on the surface of the first mid-frame facing away from the folding mechanism, and the second sound-emitting unit also emits sound through the third sound outlet; or, the electronic device further includes a third sound-emitting unit, which is fixed in the internal space and emits sound through the third sound outlet.

[0016] It is understood that the electronic device in this embodiment may also include a third sound outlet. The third sound outlet is formed on the surface of the first middle frame facing away from the folding mechanism. Thus, when the electronic device is in the closed state, the third sound outlet can still be exposed to the external environment. At this time, the electronic device can simultaneously emit sound through both the first and third sound outlets, achieving an external speaker function. The relatively large distance between the first and third sound outlets allows the electronic device to achieve a better stereo sound effect, resulting in a better user experience.

[0017] In one possible implementation, the diaphragm of the first sound-emitting unit is positioned facing the first cover plate. In this way, the first sound-emitting unit can emit sound effectively through the first sound outlet located on the first cover plate.

[0018] In one possible implementation, the electronic device further includes a bracket fixed in the internal space. The bracket has a first sound outlet channel, which connects the front cavity of the first sound-emitting unit with the first sound outlet. The first sound-emitting unit emits sound through the first sound outlet channel and the first sound outlet.

[0019] It is understood that the electronic device in this embodiment also includes a bracket. The bracket may have a first sound outlet channel. The first sound outlet channel may connect the front cavity of the first sound-emitting unit and the first sound outlet. In this way, on the one hand, the first sound-emitting unit can emit sound through the first sound outlet channel of the bracket; on the other hand, the bracket structure is relatively simple and can be manufactured independently, which helps to reduce the manufacturing difficulty and is easy to assemble.

[0020] In one possible implementation, the bracket is fixed between the first sound-emitting unit and the first cover plate, and the bracket and the diaphragm of the first sound-emitting unit surround the front cavity of the first sound-emitting unit.

[0021] In this way, the bracket can surround the front cavity of the first sound unit with the first sound unit, so that the first sound outlet channel located on the bracket can easily connect to the front cavity. The overall structure is simple and easy to assemble.

[0022] In one possible implementation, the electronic device further includes a waterproof adhesive, which is fixedly connected between the bracket and the first cover plate and is disposed around the opening of the first sound outlet near the first sound port.

[0023] In this way, the waterproof adhesive can prevent water, moisture, and other liquids from the external environment from entering the internal space of the electronic device through the first sound outlet, thus preventing damage to the device. This helps to improve the waterproof performance of the electronic device and extend its service life.

[0024] In one possible implementation, the support also has a receiving space located on the side of the support close to the first sound unit, the diaphragm of the first sound unit is received in the receiving space, and at least part of the receiving space constitutes the front cavity of the first sound unit; or, the first sound unit is located outside the receiving space, and the diaphragm of the first sound unit faces the receiving space, and the receiving space constitutes at least part of the front cavity of the first sound unit.

[0025] In this way, the bracket can surround the front cavity of the first sound unit with the first sound unit, so that the first sound outlet channel located on the bracket can easily connect to the front cavity. The overall structure is simple and easy to assemble.

[0026] In one possible implementation, a first mounting groove is provided on the side of the first middle frame near the folding mechanism of the electronic device. The first mounting groove is spaced apart from the internal space. A portion of the folding mechanism is installed in the first mounting groove. The first mounting groove has a bottom wall that is parallel to the first cover plate and is fixedly connected to the first cover plate. A portion of the bracket extends between the bottom wall of the groove and the first cover plate. At least a portion of the projection of the first sound outlet on the plane where the bottom wall of the groove is located overlaps with the bottom wall of the groove.

[0027] In this way, the first sound outlet can be positioned close to the folding mechanism, and the distance between the first and second sound outlets is relatively large, so that when the electronic device is played aloud, it can obtain a better stereo sound effect through the first and second / third sound outlets, resulting in a better user experience.

[0028] In one possible implementation, the projection of the opening of the first sound outlet towards the first sound port onto the plane of the first cover plate is the first projection, and the projection of the first sound-emitting unit onto the plane of the first cover plate is the second projection. The overlapping area of ​​the first projection and the second projection is greater than the overlapping area of ​​the first sound port and the second projection.

[0029] In this way, the opening size of the first sound outlet channel facing the first sound outlet is relatively large, and the area of ​​the opening of the first sound outlet channel facing the first sound outlet opposite the diaphragm of the first sound unit is relatively large, which makes the diaphragm of the first sound unit have a larger sound output area, which is beneficial to improving the acoustic performance of the first sound unit and improving the audio performance of electronic devices.

[0030] In one possible implementation, the first cover plate further includes a mounting hole spaced apart from the first sound outlet, and the electronic device further includes a second display screen fixed to the mounting hole.

[0031] In this way, when the electronic device is in the closed state, the user can operate the electronic device through the second display screen.

[0032] In one possible implementation, the electronic device further includes a second display screen, which is fixed to the first frame and together with the first frame encloses an internal space. A protective cover for the second display screen constitutes the first cover, and the first sound outlet is spaced apart from the display area of ​​the second display screen. Thus, when the electronic device is in a closed state, the user can operate the electronic device through the second display screen. Attached Figure Description

[0047] The embodiments of this application are described below with reference to the accompanying drawings.

[0048] In the description of the embodiments of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, "connection" can be a detachable connection or a non-detachable connection; it can be a direct connection or an indirect connection through an intermediate medium. "Fixed connection" refers to a connection where the relative positional relationship remains unchanged after connection. The directional terms mentioned in the embodiments of this application, such as "upper," "lower," "inner," and "outer," are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application. "Multiple" refers to at least two.

[0049] In the embodiments of this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0050] In the embodiments of this application, "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0051] References to "one embodiment" or "some embodiments" as used in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, phrases such as "in one embodiment," "in some embodiments," "in other embodiments," and "in another embodiment" appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0052] It is understood that the specific embodiments described herein are merely for explaining the relevant application and not for limiting the application. It should also be noted that, for ease of description, only the parts relevant to the application are shown in the accompanying drawings.

[0053] Figure 1 is a schematic diagram of the electronic device 1000 provided in the present application when it is in the open state. Figure 2 is a schematic diagram of the electronic device 1000 shown in Figure 1 when it is in the closed state. Figure 3 is a schematic diagram of the electronic device 1000 shown in Figure 1 from another perspective. Figure 4 is a partially exploded schematic diagram of the electronic device 1000 shown in Figure 1 in some embodiments.

[0054] As shown in Figures 1 to 4, the electronic device 1000 can be a foldable terminal device capable of playing sound, such as a mobile phone or tablet computer. Figure 1 illustrates the electronic device 1000 using a mobile phone as an example. It should be noted that Figures 1 to 4 and the related figures below only schematically show some components included in the electronic device 1000; the actual shape, size, position, and structure of these components are not limited by Figure 1 and the figures below. For example, the width direction of the electronic device 1000 can be the X-axis direction, the length direction can be the Y-axis direction, and the thickness direction can be the Z-axis direction.

[0055] For example, the electronic device 1000 may include a first housing 100, a second housing 200, a folding mechanism 300, a first display screen 400, and a second display screen 500. The folding mechanism 300 may connect the first housing 100 and the second housing 200. The folding mechanism 300 may deform so that the first housing 100 and the second housing 200 can be relatively unfolded to an open state (as shown in FIG. 1), or relatively folded to a closed state (as shown in FIG. 2). The electronic device may also be in an intermediate state between the open state and the closed state. The intermediate state may be any state between the open state and the closed state.

[0056] For example, the first display screen 400 can be fixedly connected to the first housing 100 and the second housing 200. The second display screen 500 can be fixedly connected to the first housing 100. The first display screen 400 can be a flexible screen, capable of deformation. The second display screen 500 can be a rigid screen. When the electronic device 1000 is in the open state, the first housing 100 and the second housing 200 can be relatively flattened. At this time, the first display screen 400 can be relatively flattened for full-screen display. The electronic device 1000 can have a large display area. The orientation of the first display screen 400 can be opposite to that of the second display screen 500. When the electronic device 1000 is in the closed state, the first housing 100 and the second housing 200 can be relatively folded. At this time, the first display screen 400 can be located between the first housing 100 and the second housing 200. The second display screen 500 can be located on the side of the first housing 100 facing away from the second housing 200. The user can operate the second display screen 500 to achieve human-computer interaction. In other words, the first display screen 400 can be an inner screen, and the second display screen 500 can be an outer screen. The electronic device 1000 in this embodiment can be an inward-folding device. In other embodiments, the electronic device 1000 may not include the first display screen 400 or the second display screen 500.

[0057] For example, the electronic device 1000 may also include multiple components (not shown in the figure), which are installed inside the first housing 100 or the second housing 200. These components may include, for example, a processor, internal memory, an external memory interface, a universal serial bus (USB) interface, a charging management module, a power management module, a battery, an antenna, a communication module, a camera, an audio module, a speaker, a receiver, a microphone, a headphone jack, a sensor module, buttons, a motor, an indicator, and a subscriber identification module (SIM) card interface, etc.

[0058] In this embodiment, the electronic device 1000 is described as having a two-fold structure, meaning that the electronic device 1000 includes two flat plate parts and a bent portion connecting the two flat plate parts. The two flat plate parts can rotate towards each other to overlap (corresponding to the closed state mentioned earlier), giving the electronic device 1000 a two-layer shape; the two flat plate parts can also rotate away from each other to flatten (corresponding to the open state mentioned earlier). In other embodiments, the electronic device 1000 can also have a three-fold or more-fold structure, meaning that the electronic device 1000 includes three or more flat plate parts, with adjacent flat plate parts connected by a bent portion, and adjacent flat plate parts can rotate relative to each other to overlap or away from each other to flatten. When the electronic device 1000 has a three-fold or more-fold structure, the structure of the electronic device 1000 can be adapted by referring to the description of the two-fold structure in this embodiment, and will not be repeated here.

[0059] It should be understood that both the first housing 100 and the second housing 200 are housing components used to mount and secure other parts of the electronic device 1000, and have diverse structures. The folding mechanism 300 is used to realize the relative movement between the first housing 100 and the second housing 200, and also has diverse structures. The embodiments of this application do not strictly limit the specific structures of the first housing 100, the second housing 200, and the folding mechanism 300. The accompanying drawings of this application only illustrate the general structure of the first housing 100, the second housing 200, and the folding mechanism 300 in one embodiment.

[0060] In other embodiments, the electronic device 1000 may also exclude the second housing 200 and the folding mechanism 300.

[0061] As shown in Figures 1 to 4, the electronic device 1000 may further include a first sound-emitting unit 10 and a second sound-emitting unit 20. Both the first sound-emitting unit 10 and the second sound-emitting unit 20 can be mounted on the first housing 100. The first sound-emitting unit 10 and the second sound-emitting unit 20 may be offset in the thickness direction of the electronic device 1000 (e.g., the Z-axis direction). The electronic device 1000 may also have a first sound outlet 101 and a second sound outlet 102. Both the first sound outlet 101 and the second sound outlet 102 may be located in the first housing 100. The first sound outlet 101 and the second sound outlet 102 have different orientations. The first sound outlet 101 may have the same orientation as the second display screen 500, that is, opposite to the orientation of the first display screen 400. The first sound-emitting unit 10 can emit sound through the first sound outlet 101. The second sound outlet 102 may have the same orientation as the first display screen 400. The second sound-emitting unit 20 can emit sound through the second sound outlet 102.

[0062] For example, when the electronic device 1000 is in the open state, the second sound outlet 102 can face the user. At this time, the second sound unit 20 can function as a receiver. The second sound outlet 102 can be considered as an inner screen earpiece slit. The user can make voice calls through the second sound unit 20. When the electronic device 1000 is in the closed state, the second sound outlet 102 can be blocked by the second housing 200. At this time, the first sound outlet 101 can face the user. The first sound unit 10 can function as a receiver. The user can make voice calls through the first sound outlet 101.

[0063] Understandably, compared to typical electronic devices that only have an inner screen earpiece slit (i.e., the second sound outlet in this embodiment), users need to keep the electronic device in the open state when making voice calls. This means that users cannot answer voice calls when the electronic device is in the closed state; they need to manually switch the electronic device from the closed to the open state to make a voice call. This process is cumbersome and results in a poor user experience. However, the electronic device 1000 in this embodiment also includes a first sound unit 10 and a first sound outlet 101. The orientation of the first sound outlet 101 can be opposite to the orientation of the first display screen 400, and the first sound unit 10 can emit sound through the first sound outlet 101. Thus, even when the electronic device 1000 is in the closed state, users can directly make voice calls through the first sound outlet 101 without needing to open the electronic device 1000 and use the second sound outlet 102, thereby effectively improving the user experience.

[0064] Secondly, compared to typical electronic devices that typically employ a single sound unit with two diaphragms arranged back-to-back to enable voice calls on both the inner and outer screens, allowing for voice communication, one diaphragm faces the first display screen while the other faces the second display screen. The front cavity of one diaphragm connects to the earpiece seam of the inner screen, and the front cavity of the other diaphragm connects to the earpiece seam of the outer screen. However, this back-to-back arrangement results in the front cavities of the two diaphragms being stacked along the thickness of the electronic device, leading to a thicker device and hindering its slim design. In contrast, the electronic device 1000 in this embodiment includes two sound units, namely a first sound unit 10 and a second sound unit 20, which are staggered along the thickness of the electronic device 1000, resulting in a thinner overall device and facilitating its slim design.

[0065] The specific structure of the electronic device 1000 will be described below with reference to the accompanying drawings.

[0066] Figure 5 is a partial cross-sectional view of the electronic device 1000 shown in Figure 1 cut along AA in some embodiments.

[0067] As shown in Figures 1, 4, and 5, the first housing 100 may include a first middle frame 110. The electronic device 1000 may also include a first cover plate 120. The first cover plate 120 may be fixedly connected to the first middle frame 110 and together with the first middle frame 110 encloses an internal space 100a. The first sound-emitting unit 10 and the second sound-emitting unit 20 may both be installed in the internal space 100a. The internal space 100a may also be used to install other devices and components of the electronic device 1000. For example, the first cover plate 120 may have a mounting hole 121. The mounting hole 121 may communicate with the internal space 100a. The second display screen 500 may be fixed to the mounting hole 121. In this case, the second display screen 500 may be spaced apart from the first sound outlet 101.

[0068] Exemplarily, the side of the first middle frame 110 near the folding mechanism 300 may also have a first mounting groove 111. A portion of the folding mechanism 300 may be mounted in the first mounting groove 111. The first mounting groove 111 may have a bottom wall 111a. The bottom wall 111a may be parallel to the first cover plate 120. The surface of the bottom wall 111a facing away from the folding mechanism 300 may face the first cover plate 120. The bottom wall 111a may be fixedly connected to the first cover plate 120.

[0069] For example, the second housing 200 may include a second middle frame 210 and a second cover plate 220. The second cover plate 220 may be fixedly connected to the second middle frame 210. The side of the second middle frame 210 near the folding mechanism 300 may have a second mounting groove 211. Part of the folding mechanism 300 may be mounted in the second mounting groove 211.

[0070] As shown in Figures 1, 4, and 5, the first sound outlet 101 can be located on the first cover plate 120. The second sound outlet 102 can be located on the first middle frame 110. Exemplarily, the second sound outlet 102 can be located on the side of the first middle frame 110 away from the folding mechanism 300. The orientation of the second sound outlet 102 is the same as the orientation of the first display screen 400 (see Figure 3). The first sound outlet 101 can be positioned closer to the folding mechanism 300 than the second sound outlet 102. For example, the first sound outlet 101 can be located on the side of the first cover plate 120 near the folding mechanism 300. When the electronic device 1000 is in a closed state (see Figure 2), the first sound outlet 101 can be exposed to the external environment. The second sound outlet 102 can face the second housing 200 and be blocked by the second housing 200.

[0071] Exemplarily, the first middle frame 110 may also have a third sound outlet 103. The third sound outlet 103 may be located on the side of the first middle frame 110 away from the folding mechanism 300. For example, the third sound outlet 103 may be formed on the surface of the first middle frame 110 facing away from the folding mechanism 300. When the electronic device 1000 is in the open state and the user holds the electronic device 1000, the third sound outlet 103 may face the sky. When the electronic device 1000 is in the closed state, the third sound outlet 103 may still be exposed to the external environment. The user can use the third sound outlet 103 to achieve external sound output. Exemplarily, the second sound unit 20 may also emit sound through the third sound outlet 103. In some embodiments, the electronic device 1000 may also include a third sound unit (not shown). The third sound unit may be installed in the internal space 100a. The third sound unit may emit sound through the third sound outlet 103.

[0072] Understandably, compared to typical electronic devices where the sound outlet is located on the middle frame, requiring the sound-emitting unit to be positioned close to the edge of the middle frame, the sound-emitting unit's position is relatively fixed, which is not conducive to flexible layout of the internal components. In this embodiment, the first sound outlet 101 is located on the first cover plate 120, making the placement of the first sound-emitting unit 10 more flexible and adaptable to different component layouts of the electronic device 1000.

[0073] Secondly, the electronic device 1000 in this embodiment is a foldable device, and the first sound outlet 101 is located on the first cover plate 120. In this way, when the electronic device 1000 is in the closed state, the first sound outlet 101 is not blocked by the second housing 200, and the first sound outlet 101 can be exposed to the external environment, so that the user can use the first sound outlet 101 to make voice calls even when the electronic device 1000 is in the closed state, resulting in a better user experience.

[0074] Secondly, the electronic device 1000 in this embodiment also includes a second audio output port 102, which is located in the first middle frame 110. The orientation of the second audio output port 102 is the same as that of the first display screen 400. Thus, when the electronic device 1000 is in the open state, the user can make voice calls through the second audio output port 102; when the electronic device 1000 is in the closed state, the user can make calls through the first audio output port 101. In other words, regardless of the state of the electronic device 1000, the user can make voice calls using either the first audio output port 101 or the second audio output port 102, resulting in a better user experience.

[0075] In addition, in this embodiment, the first sound outlet 101 can be positioned closer to the folding mechanism 300 than the second sound outlet 102. This way, when the electronic device 1000 is playing music, the distance between the first sound outlet 101 and the second sound outlet 102 is greater, allowing the electronic device 1000 to achieve better stereo sound effects and a better user experience.

[0076] Furthermore, the electronic device 1000 in this embodiment may also include a third sound outlet 103. The third sound outlet 103 is formed on the surface of the first middle frame 110 facing away from the folding mechanism 300. Thus, when the electronic device 1000 is in a closed state, the third sound outlet 103 can still be exposed to the external environment. At this time, the electronic device 1000 can simultaneously emit sound through both the first sound outlet 101 and the third sound outlet 103, realizing an external speaker function. The relatively large distance between the first sound outlet 101 and the third sound outlet 103 allows the electronic device 1000 to achieve a better stereo sound effect, resulting in a better user experience.

[0077] Figure 6 is a partial structural schematic diagram of the electronic device 1000 shown in Figure 1 at point B. Figure 7 is an exploded structural schematic diagram of the structure shown in Figure 6 in some embodiments. Figure 8 is a structural schematic diagram of the bracket shown in Figure 7 from another perspective. Figure 9 is a partial cross-sectional structural schematic diagram of one embodiment of the structure shown in Figure 6 cut along point CC.

[0078] As shown in Figures 6 to 9, the electronic device 1000 may further include a bracket 30, a waterproof adhesive 40, and a dustproof mesh 50. The bracket 30 may have a receiving space 30a and a first sound output channel 30b. The receiving space 30a may be connected to the first sound output channel 30b.

[0079] For example, the bracket 30 may include a plate 31 and a frame 32. The frame 32 may be fixed to one side of the plate 31. A first sound outlet channel 30b may be formed in the plate 31. The frame 32 may be used with the plate 31 to enclose a receiving space 30a. It should be noted that although the bracket 30 is described in this embodiment as divided into two parts (i.e., the plate 31 and the frame 32), it does not affect the fact that the bracket 30 is an integrally formed structure, that is, the plate 31 and the frame 32 can be integrally formed. In Figure 9, the plate 31 and the frame 32 of the bracket 30 are schematically divided by dashed lines.

[0080] Figure 10 is a schematic diagram of the assembly structure of the first middle frame 110, the first sound-generating unit 10, the bracket 30, and the waterproof adhesive 40 shown in Figure 7 in some embodiments. Figure 11 is a schematic diagram of the cross-sectional structure of the structure shown in Figure 6 cut along CC in one embodiment.

[0081] As shown in Figures 10 and 11, the first sound-emitting unit 10 can be fixedly connected to the first middle frame 110. The diaphragm 11 of the first sound-emitting unit 10 can be positioned facing the first cover plate 120. The second sound-emitting unit 20 (see Figure 1) can be fixedly connected to the first middle frame 110. The diaphragm of the second sound-emitting unit 20 (not shown) can be positioned facing away from the first cover plate 120. The diaphragm of the second sound-emitting unit 20 and the first middle frame 110 can enclose the front cavity of the second sound-emitting unit 20.

[0082] Exemplarily, the bracket 30 can be fixed to the internal space 100a. The bracket 30 can be fixedly connected to the first sound-emitting unit 10. The bracket 30 and the diaphragm 11 of the first sound-emitting unit 10 can enclose the front cavity 12 of the first sound-emitting unit 10. The receiving space 30a of the bracket 30 can be located on the side of the bracket 30 closer to the first sound-emitting unit 10. At least a portion of the first sound-emitting unit 10 can be received in the receiving space 30a of the bracket 30. At this time, at least a portion of the receiving space 30a can constitute the front cavity 12 of the first sound-emitting unit 10. The receiving space 30a can provide vibration space for the diaphragm 11 of the first sound-emitting unit 10. The first sound outlet channel 30b can connect the front cavity 12 of the first sound-emitting unit 10 and the first sound outlet 101. The first sound-emitting unit 10 can emit sound through the first sound outlet channel 30b and the first sound outlet 101. In other embodiments, the first sound-emitting unit 10 may also be located outside the receiving space 30a, and the diaphragm 11 of the first sound-emitting unit 10 may face the receiving space 30a and be exposed in the receiving space 30a. In this case, the receiving space 30a may constitute at least part of the front cavity 12 of the first sound-emitting unit 10.

[0083] Exemplarily, the frame 32 of the bracket 30 can be fixedly connected to the first sound-generating unit 10. The plate 31 of the bracket 30 can be located on the side of the frame 32 facing away from the first sound-generating unit 10. The diaphragm 11 of the first sound-generating unit 10 can be exposed relative to the receiving space 30a. The diaphragm 11 can be spaced apart from the plate 31. In some embodiments, the frame 32 of the bracket 30 can be fixedly connected to the first sound-generating unit 10 by an adhesive layer. In this case, the front cavity 12 of the first sound-generating unit 10 can be isolated from the internal space 100a.

[0084] For example, the waterproof adhesive 40 can be fixedly connected between the plate 31 of the bracket 30 and the first cover plate 120. The waterproof adhesive 40 can be disposed around the opening of the first sound outlet channel 30b near the first sound outlet 101. In this way, the waterproof adhesive 40 can prevent water, water vapor and other liquids in the external environment from entering the internal space 100a of the electronic device 1000 through the first sound outlet 101 and causing damage to the device, which is beneficial to improving the waterproof performance of the electronic device 1000 and extending the service life of the electronic device 1000.

[0085] For example, the dustproof net 50 can be fixed to the plate 31 of the bracket 30 and / or the first cover plate 120. The dustproof net 50 can cover the first sound outlet 101. In this way, the dustproof net 50 can prevent dust and other impurities from entering the interior of the electronic device 1000 through the first sound outlet 101, affecting the normal operation of the device, and helping to extend the service life of the electronic device 1000.

[0086] It is understood that the electronic device 1000 in this embodiment also includes a bracket 30. The bracket 30 may have a first sound outlet channel 30b. The first sound outlet channel 30b may connect the front cavity 12 of the first sound-emitting unit 10 and the first sound outlet 101. In this way, on the one hand, the first sound-emitting unit 10 can emit sound through the first sound outlet channel 30b of the bracket 30; on the other hand, the bracket 30 has a relatively simple structure and can be manufactured independently, which helps to reduce the manufacturing difficulty and is easy to assemble.

[0087] Secondly, by setting up the bracket 30, the waterproof adhesive 40 can be better fixed between the plate 31 of the bracket 30 and the first cover plate 120, thereby improving the waterproof capability of the electronic device 1000 and extending the service life of the electronic device 1000.

[0088] Figure 12 is a schematic diagram of the structure shown in Figure 6 from another perspective.

[0089] As shown in Figures 10 to 12, a portion of the plate 31 of the bracket 30 can extend between the bottom wall 111a of the first mounting groove 111 and the first cover plate 120. At least a portion of the projection of the first sound outlet 101 onto the plane containing the bottom wall 111a can overlap with the bottom wall 111a. Thus, the first sound outlet 101 can be positioned close to the folding mechanism 300, and the distance between the first sound outlet 101 and the second sound outlet 102 is relatively large. This allows the electronic device 1000 to achieve better stereo sound through the first sound outlet 101 and the second / third sound outlet 102 when playing external audio, resulting in a better user experience.

[0090] For example, along the thickness direction of the electronic device 1000 (e.g., the Z-axis direction), the projection of the opening of the first sound outlet channel 30b toward the first sound outlet 101 onto the plane of the first cover plate 120 is the first projection 30b1. Along the thickness direction of the electronic device 1000 (e.g., the Z-axis direction), the projection of the diaphragm 11 of the first sound-emitting unit 10 onto the plane of the first cover plate 120 is the second projection 13. It should be noted that the first projection 30b1 and the second projection 13 are illustrated by dashed lines in Figure 12. The overlap area between the first projection 30b1 and the second projection 13 can be greater than the overlap area between the first sound outlet 101 and the second projection 13. In this way, the opening size of the first sound outlet channel 30b facing the first sound outlet 101 is relatively large, and the area of ​​the opening of the first sound outlet channel 30b facing the first sound outlet 101 directly opposite the diaphragm 11 of the first sound unit 10 is relatively large, which makes the diaphragm 11 of the first sound unit 10 have a larger sound output area, which is beneficial to improving the acoustic performance of the first sound unit 10 and improving the audio performance of the electronic device 1000.

[0091] For example, along the thickness direction of the electronic device 1000, the projection of the dustproof mesh 50 onto the plane of the first cover plate 120 can cover the first sound outlet 101. In this way, the dustproof mesh 50 can effectively prevent wall dust and other impurities from entering the interior of the electronic device 1000 through the first sound outlet 101.

[0092] For example, the dustproof mesh 50 can be spaced apart from the wall of the first sound outlet channel 30b (see Figure 10). When the first sound-emitting unit 10 is working, the sound emitted by the first sound-emitting unit 10 can pass through the dustproof mesh 50 and be emitted through the first sound outlet 101, and can also pass through the space between the dustproof mesh 50 and the wall of the first sound outlet channel 30b and be emitted through the first sound outlet 101.

[0093] In other embodiments, the opening size of the first sound channel 30b toward the first sound port 101 may also be the same as the size of the first sound port 101.

[0094] Figure 13 is a schematic diagram of the electronic device 1000 shown in Figure 1 in another embodiment.

[0095] As shown in Figure 13, the structure of the electronic device 1000 in this embodiment is roughly the same as that of the electronic device 1000 shown in Figure 1, and the similarities will not be described again. The differences between the two are described below. In this embodiment, the second display screen 500 can be fixedly connected to the first middle frame 110, and together with the first middle frame 110, it encloses an internal space (not shown). At this time, the protective cover 501 of the second display screen 500 can constitute the first cover 120. The first sound outlet 101 can be located on the first cover 120. The first sound outlet 101 can be spaced apart from the display area 502 of the second display screen 500. The protective cover 501 can be made of transparent glass. Exemplarily, the second display screen 500 can include a display panel (not shown) and a protective cover 501 stacked together. The protective cover 501 can be located on the display side of the display panel. The protective cover 501 can be fixedly connected to the first middle frame 110. The first sound outlet 101 can be spaced apart from the display panel.

[0096] It should be noted that, in the absence of conflict, the features in the embodiments of this application can be combined with each other, and any combination of features in different embodiments is also within the protection scope of this application. That is to say, the multiple embodiments described above can also be arbitrarily combined according to actual needs.

[0097] It should be noted that all the above figures are exemplary illustrations of this application and do not represent the actual size of the product. Furthermore, the dimensional proportions between the components in the figures are not intended to limit the actual product of this application.

[0098] The above are merely some embodiments of this application, and the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
