Description

Technical Field

[0001] This application relates to the field of terminal equipment, and more particularly to an electronic device and its housing. Background Technology

[0002] With the continuous development of technology, users' requirements for the acoustic performance of mobile phones and other electronic devices are constantly increasing. Current electronic devices typically have their casings hollowed out to create sound outlets or channels for the speaker unit to produce sound. However, hollowing out the casing to create these outlets or channels reduces the structural strength of the casing, making it more susceptible to damage from external forces. This is especially true when electronic devices have multiple outlets or channels, as the structural strength of the casing is significantly affected, reducing the lifespan of the electronic device. Summary of the Invention

[0003] This application provides an electronic device and device housing that balances sound output quality and structural strength.

[0004] In a first aspect, an electronic device is provided. The electronic device includes a first housing and a first sound-emitting unit. The first housing has a first mounting space, a sound outlet duct, and a first sound outlet. The first mounting space is connected to an external space of the first housing via the sound outlet duct and the first sound outlet. The first sound-emitting unit is fixed to the first mounting space. The first sound-emitting unit emits sound to the external environment of the electronic device via the sound outlet duct and the first sound outlet. The electronic device also includes buttons. The first housing further has a first mounting groove. The buttons are mounted in the first mounting groove, and at least a portion of the first mounting groove constitutes at least a portion of the sound outlet duct.

[0005] It is understandable that conventional electronic devices typically hollow out part of their casing to form a sound outlet for the sound-generating unit. However, this reduces the structural strength of the casing, making it more susceptible to damage from external forces and thus shortening the lifespan of the electronic device. In this embodiment, the electronic device incorporates a first mounting slot for mounting buttons as part of the sound outlet for the first sound-generating unit. Thus, the first mounting slot serves two purposes: firstly, it accommodates the buttons and acts as a travel path for them; secondly, the first sound-generating unit can utilize at least a portion of the first mounting slot for sound generation. In other words, the buttons and the sound outlet reuse the space of the first mounting slot, thereby reducing the space required for forming the sound outlet and mounting the buttons and related components within the casing. This ensures sufficient structural strength for the casing and contributes to extending the lifespan of the electronic device. In short, the electronic device in this embodiment improves structural strength while maintaining good sound quality.

[0006] In one possible implementation, the first mounting slot and the first sound outlet are arranged at intervals along the thickness direction of the first housing. This allows the first mounting slot and the first sound outlet to reuse space in the planes containing the length and width of the electronic device, thus saving space.

[0007] In one possible implementation, the electronic device further includes a first screen. The first screen is fixedly connected to the first housing. The first sound outlet and the first screen are located on different sides of the first housing.

[0008] Understandably, compared to electronic devices where the first sound outlet and the first screen are formed on the same side of the first housing, the first sound outlet occupies part of the space of the first screen, thus reducing the display area of ​​the first screen and affecting the user experience. However, in this embodiment, the first sound outlet and the first screen of the electronic device are located on different sides of the first housing, allowing them to be situated on different planes of the first housing. This prevents the first sound outlet from occupying space on the first screen, enabling the first screen to have a larger display area and thereby improving the user experience.

[0009] In one possible implementation, the first housing includes a first middle frame and a first rear cover. The first middle frame includes a middle plate and a frame. The frame is fixedly connected to the periphery of the middle plate and, together with the middle plate, encloses a first mounting space. The first rear cover is fixedly connected to the frame and covers the first mounting space. A first screen is located on the side of the first middle frame facing away from the first rear cover and is fixedly connected to the first middle frame. A first sound outlet is formed on the first rear cover or the frame.

[0010] Understandably, compared to electronic devices where the first sound outlet is located on the first screen, the first sound outlet occupies space on the first screen, thus reducing the display area and affecting the user experience. However, in this embodiment, the first sound outlet of the electronic device is located on the first back cover or bezel. Therefore, the first sound outlet does not occupy space on the first screen, allowing the first screen to have a larger display area, thereby improving the user experience.

[0011] In one possible implementation, the first mounting slot is located on the frame. The opening of the first mounting slot is formed on the surface of the frame facing away from the first mounting space.

[0012] Understandably, compared to electronic devices where the first mounting slot is formed on the middle plate, the first mounting slot requires more space in the first housing to allow the button to be exposed relative to the first housing when mounted in the first mounting slot. However, in this embodiment, the first mounting slot is located on the edge, and the opening is formed on the surface of the edge facing away from the first mounting space. This allows the button to be more easily exposed relative to the first housing when mounted in the first mounting slot, and the space required by the first mounting slot is small, thus saving space in the electronic device.

[0013] In one possible implementation, the frame also has a first hole. The first hole connects the first mounting slot and the first sound outlet. The first hole and the first mounting slot together constitute at least a portion of the sound outlet duct. Thus, the first mounting space can connect to the external space of the electronic device by sequentially passing through the first mounting slot, the first hole, and the first sound outlet. The first sound-emitting unit can emit sound to the external space of the electronic device by sequentially passing through the first mounting slot, the first hole, and the first sound outlet.

[0014] In one possible implementation, there are multiple first holes. These multiple first holes are spaced apart from each other.

[0015] Understandably, compared to electronic devices with only one first hole, the first hole is typically designed as a large through-hole to ensure sound can travel from the first mounting slot through the first hole to the first sound outlet. However, a large opening area for the first hole results in a smaller solid material area for the first housing, reducing its structural strength and making it more susceptible to damage from external forces, thus affecting the lifespan of the electronic device. In this embodiment, the electronic device can have multiple first holes, spaced apart from each other. This reduces the opening area of ​​the first housing, allowing it to have sufficient solid material, ensuring adequate structural strength and thus improving the lifespan of the electronic device.

[0016] In one possible implementation, the first mounting groove has an inner peripheral side surface and a groove bottom surface. The inner peripheral side surface surrounds the groove bottom surface. The button includes a first portion and a second portion that are connected. The second portion is positioned closer to the groove bottom surface than the first portion. A gap exists between the surface of the first portion facing the second portion and the groove bottom surface. The gap constitutes at least a portion of the sound outlet duct.

[0017] In this way, the button does not occupy the entire space of the first mounting slot, and the first sound unit can use the gap between the first mounting slot and the bottom surface of the slot to produce sound. At this time, the button and the first sound unit reuse the space of the first mounting slot, thereby saving space in the electronic device.

[0018] In one possible implementation, the frame of the first housing also has a sound outlet groove. The sound outlet groove connects the first hole and the first sound outlet of the first housing. The sound outlet groove, the first hole, and the first mounting groove together constitute at least a portion of the sound outlet duct. The electronic device also includes a dustproof mesh. The dustproof mesh is located inside the sound outlet groove and is fixedly connected to the first housing. The dustproof mesh covers the first sound outlet. In this way, the dustproof mesh can prevent dust or other debris from entering the first sound outlet, thereby preventing the first sound outlet from being blocked and improving the sound output stability of the electronic device.

[0019] In one possible implementation, the first sound-emitting unit and the first housing enclose a sound-emitting space, or the first sound-emitting unit has a sound-emitting space. The sound-emitting space is connected to a sound-exiting pipe. The first sound-emitting unit includes a first diaphragm. At least a portion of the first diaphragm is exposed relative to the sound-emitting space. The first sound-emitting unit emits sound to the external space of the electronic device by passing sequentially through the sound-emitting space, the sound-exiting pipe, and the first sound-exiting port. Thus, when the first sound-emitting unit is operating, the first diaphragm can push the air in the sound-emitting space, passing sequentially through the sound-exiting pipe and the first sound-exiting port, to emit sound to the external environment of the electronic device. The sound-emitting space and the sound-exiting pipe can together constitute at least a portion of the front cavity of the first sound-emitting unit.

[0020] In one possible implementation, the first mounting slot and the sound-emitting space are spaced apart. The first housing also has a connecting pipe. The connecting pipe connects the first mounting slot and the sound-emitting space. The connecting pipe and the first mounting slot together constitute at least a portion of the sound-emitting pipe. Thus, when the first sound-emitting unit is operating, the first diaphragm can push the air in the sound-emitting space, passing sequentially through the connecting pipe and the first sound outlet, to emit sound to the external environment of the electronic device. The sound-emitting space, the connecting pipe, and the first mounting slot can together constitute at least a portion of the front cavity of the first sound-emitting unit.

[0021] In one possible implementation, the frame of the first housing has a first channel. The first channel connects the first mounting slot and the sound-emitting space. The first channel constitutes at least part of a connecting conduit. Thus, the sound-emitting space can sequentially pass through the first channel, the first mounting slot, and the first sound outlet to connect to the external space of the electronic device. When the first sound-emitting unit operates, the first diaphragm can push air within the sound-emitting space, sequentially passing through the first channel, the first mounting slot, and the first sound outlet, to emit sound to the external environment of the electronic device. The sound-emitting space, the first channel, and the first mounting slot can collectively constitute at least part of the front cavity of the first sound-emitting unit.

[0022] In one possible implementation, the middle plate of the first housing has a second channel. The second channel connects the first channel and the sound-emitting space. The first and second channels together constitute at least a portion of a connecting conduit. Thus, the sound-emitting space can sequentially pass through the first channel, the second channel, the first mounting slot, and the first sound outlet to connect to the external space of the electronic device. When the first sound-emitting unit operates, the first diaphragm can push the air within the sound-emitting space, sequentially passing through the first channel, the second channel, the first mounting slot, and the first sound outlet, to emit sound to the external environment of the electronic device. The sound-emitting space, the first channel, the second channel, and the first mounting slot can together constitute at least a portion of the front cavity of the first sound-emitting unit.

[0023] In one possible implementation, the electronic device further includes a second sound-emitting unit. The second sound-emitting unit is mounted in the first mounting space. The first housing also has a second sound outlet. The second sound outlet connects the first mounting space and the external space of the first housing. The orientation of the second sound outlet is different from that of the first sound outlet. The second sound-emitting unit emits sound to the external environment of the electronic device through the second sound outlet.

[0024] Understandably, compared to electronic devices where the first and second sound output ports face the same direction, users are more likely to simultaneously block both ports during calls, affecting the sound output quality. However, in this embodiment, the first and second sound output ports face different directions, preventing users from blocking both ports simultaneously during calls. This improves sound stability and enhances the user experience.

[0025] In one possible implementation, the electronic device further includes a second housing and a folding mechanism. The folding mechanism connects the first housing and the second housing. The first housing and the second housing can be unfolded relative to each other to an open state or folded relative to each other to a closed state under the action of the folding mechanism. A first screen of the electronic device is fixedly connected to the first housing and the second housing. When the electronic device is in the open state, the first housing and the second housing are relatively flat, the first screen and the second sound outlet are located on the same side of the first housing and the second housing, and the second sound unit acts as a receiver. When the electronic device is in the closed state, the first housing and the second housing are folded relative to each other. The first screen is located between the first housing and the second housing. The first screen blocks the second sound outlet, and the first sound unit acts as a receiver.

[0026] Understandably, typical foldable electronic devices only have a single earpiece slit, requiring the user to maintain a specific state for calls. For example, when an electronic device only has an inner screen earpiece slit, the slit is visible when the device is open, allowing the user to make calls through it. However, when the device is closed, the slit is located inside the device and is obscured by the folded screen, preventing the user from making calls through it. In other words, when the device only has an inner screen earpiece slit, the user must keep the device open to make and receive calls, making the process cumbersome and resulting in a poor user experience. The electronic device in this embodiment can have both a first and a second audio output. The first and second audio outputs face different directions. The second audio output serves as the inner screen earpiece slit. When the device is open, the second sound unit acts as a receiver, and the second audio output is visible relative to the first screen. The second sound unit and the second audio output can work together, allowing the user to make calls even when the device is open. When the electronic device is in the closed state, the first sound unit can function as a receiver, the second sound outlet is blocked by the folded first screen, while the first sound outlet remains exposed. The first sound unit and the first sound outlet can cooperate with each other, allowing the user to make calls even when the electronic device is in the closed state. In other words, regardless of whether the electronic device in this embodiment is in the open or closed state, the user can use the corresponding earpiece opening to make calls, resulting in a better user experience.

[0027] Secondly, a device housing is provided. The device housing has a first mounting space, a sound outlet duct, and a first sound outlet. The first mounting space is connected to an external space of the device housing via the sound outlet duct and the first sound outlet. The device housing also has a first mounting groove. The first mounting groove constitutes at least a portion of the sound outlet duct. The first mounting groove is used to mount buttons.

[0028] Understandably, conventional device housings typically involve partially hollowing out the casing to create the sound outlet channel. However, this reduces the structural strength of the housing, making it more susceptible to damage from external forces and thus shortening its lifespan. In this embodiment, the device housing incorporates the first mounting slot, intended for installing buttons, as part of the sound outlet channel. Thus, the first mounting slot serves two purposes: firstly, it accommodates the buttons and acts as a travel path for them; secondly, it also functions as part of the sound outlet channel. In other words, the buttons and the sound outlet channel reuse the space of the first mounting slot, reducing the overall dimensions of the housing for creating the sound outlet channel and for mounting the buttons and related components. This ensures the structural strength of the housing and contributes to extending its lifespan.

[0029] In one possible implementation, the device housing includes a first middle frame and a first rear cover. The first middle frame includes a middle plate and a side frame. The side frame is fixedly connected to the periphery of the middle plate and, together with the middle plate, encloses a first mounting space. The first rear cover is fixedly connected to the side frame and covers the first mounting space. A first sound outlet is formed in the first rear cover or the side frame.

[0030] Understandably, compared to a device housing where the first sound outlet is formed on the middle plate, the first sound outlet requires more space to connect to the external space of the device housing. However, in this embodiment, the first sound outlet of the device housing is formed on the first rear cover or frame, allowing the first sound outlet to connect to the external space of the device housing while occupying less space, thereby saving space in the electronic device.

[0031] In one possible implementation, the first mounting slot is located on the edge of the frame. The opening of the first mounting slot is formed on the surface of the frame facing away from the first mounting space. It is understood that compared to a device housing where the first mounting slot is formed on the middle plate, the first mounting slot requires more space in the device housing to allow the button to be exposed relative to the device housing when mounted in the first mounting slot. However, in this embodiment, the first mounting slot is located on the edge of the frame, and the opening is formed on the surface of the frame facing away from the first mounting space. This allows the button to be more easily exposed relative to the device housing when mounted in the first mounting slot, and the space required by the first mounting slot is small, thus saving space in the device housing.

[0032] In one possible implementation, the frame also has a first hole. The first hole connects the first mounting slot and the first sound outlet. The first hole and the first mounting slot together constitute at least a portion of the sound outlet duct. In this way, the first mounting space can connect to the external space of the device housing by sequentially passing through the first mounting slot, the first hole, and the first sound outlet.

[0033] In one possible implementation, the first mounting groove has an inner peripheral side surface and a groove bottom surface. The inner peripheral side surface surrounds the groove bottom surface. The button includes a connected first part and a second part. The second part is positioned closer to the groove bottom surface than the first part. The surface of the first part facing the second part is positioned opposite the groove bottom surface. A gap exists between the surface of the first part facing the second part and the groove bottom surface. The gap constitutes at least a portion of the sound outlet duct.

[0034] In this way, the buttons do not occupy the entire space of the first mounting slot, and the gap between the first mounting slot and the bottom surface of the slot can form at least part of the sound outlet pipe. At this time, the buttons and the sound outlet pipe reuse the space of the first mounting slot, thereby saving space in the device housing.

[0035] In one possible implementation, the device housing also includes a connecting conduit. The connecting conduit connects the first mounting slot and the first mounting space. The connecting conduit and the first mounting slot together constitute at least a portion of the sound outlet conduit. Thus, the first mounting space can be connected to the external space of the device housing via the connecting conduit, the first mounting slot, and the first sound outlet in sequence.

[0036] In one possible implementation, the frame of the device housing has a first channel. The first channel connects a first mounting slot and a first mounting space. The first channel constitutes at least part of a connecting conduit. Thus, the first mounting space can connect to the external space of the device housing via the first channel, the first mounting slot, and the first sound outlet in sequence.

[0037] In one possible implementation, the middle plate of the device housing has a second channel. The second channel connects the first channel and the first mounting space. The first channel and the second channel together constitute at least a portion of a connecting conduit. Thus, the first mounting space can connect to the external space of the device housing via the first channel, the second channel, the first mounting slot, and the first sound outlet in sequence.

[0038] In one possible implementation, the device housing also has a second sound outlet, which connects the first mounting space and the external space of the device housing, and the orientation of the second sound outlet is different from that of the first sound outlet.

[0039] Understandably, compared to a device housing where the first and second sound outlets face the same direction, users are prone to simultaneously blocking both outlets when using the housing, causing blockages and affecting the communication between the first mounting space and the external space of the housing. However, in this embodiment, the first and second sound outlets of the device housing face different directions, thus preventing users from blocking both outlets simultaneously. This ensures that at least one outlet remains unblocked when the user is using the housing, guaranteeing communication between the first mounting space and the external space of the housing.

[0055] The embodiments of this application are described below with reference to the accompanying drawings.

[0056] 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, they should not be construed as limitations on the embodiments of this application. "Multiple" refers to at least two.

[0057] In the embodiments of this application, the terms "first," "second," "third," and "fourth" 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 with "first," "second," "third," and "fourth" may explicitly or implicitly include one or more of that feature.

[0058] 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.

[0059] 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.

[0060] It is understood that the specific embodiments described herein are merely for explaining the relevant invention and not for limiting the invention. It should also be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0061] Figure 1 This is a schematic diagram of one embodiment of the electronic device 1000 provided in this application when it is in a closed state. Figure 2 yes Figure 1 The diagram shows a structural schematic of one embodiment of the electronic device 1000 when it is in the open state. Figure 3 yes Figure 2 The diagram shows the structure of the electronic device 1000 from another perspective.

[0062] like Figures 1 to 3 As shown, the electronic device 1000 can be a device capable of playing sound, such as a mobile phone, tablet computer, multimedia player, laptop computer, foldable terminal device, television, or wearable device. Figure 1 The electronic device 1000 shown is illustrated using a mobile phone as an example. It should be noted that... Figures 1 to 3 The accompanying drawings below only schematically illustrate some components included in the electronic device 1000; the actual shape, size, location, and construction of these components are not subject to change. Figure 1 And the accompanying figures below. For ease of description, the width direction of electronic device 1000 is defined as the X-axis, the length direction as the Y-axis, and the thickness direction as the Z-axis. It is understood that the coordinate system of electronic device 1000 can be flexibly set according to specific actual needs.

[0063] For example, the electronic device 1000 may include a device housing 100, a first screen 200, and a folding mechanism 300. The device housing 100 may include a first housing 110 and a second housing 120. The folding mechanism 300 may connect the first housing 110 and the second housing 120. The folding mechanism 300 may deform to allow the first housing 110 and the second housing 120 to unfold relative to each other into an open state (e.g., ...). Figure 2 As shown), or folded relative to each other into a closed state (as shown). Figure 1 (As shown). For example, the first housing 110 and the second housing 120 may be arranged side by side along the Y-axis. In other embodiments, the first housing 110 and the second housing 120 may also be arranged side by side along the X-axis.

[0064] For example, the first screen 200 can be fixedly connected to the first housing 110 and the second housing 120. When the electronic device 1000 is in the open state, the first housing 110 and the second housing 120 can be relatively flattened. At this time, the first screen 200 can also be relatively flattened. The first screen 200 is capable of full-screen display, and the electronic device 1000 has a large display area. When the electronic device 1000 is in the closed state, the first housing 110 and the second housing 120 can be relatively folded. At this time, the first screen 200 can be located between the first housing 110 and the second housing 120. In other words, the first screen 200 can be the inner screen of the electronic device 1000. In some embodiments, the electronic device 1000 may also include a second screen. The second screen can be located on the side of the first housing 110 opposite to the first screen 200. When the electronic device 1000 is in the closed state, the second screen can be located on the side of the first housing 110 opposite to the second housing 120. In other words, the second screen can be the outer screen of the electronic device 1000. In other embodiments, the second screen may also be located on the side of the second housing 120 opposite to the first screen 200. In some other embodiments, the electronic device 1000 may not include the first screen 200.

[0065] For example, the electronic device 1000 may further include a button 500. The button 500 may be a volume control button for the electronic device 1000. The user can adjust the loudness of the sound emitted by the electronic device 1000 using the button 500. The button 500 may be elongated. The button 500 may be mounted on the first housing 110. For example, the button 500 and the first screen 200 may be located on different sides of the first housing 110. For instance, when a user holds the electronic device 1000 to make a call, the first screen 200 may face the user's ear, and the button 500 may be located on the side of the first housing 110 facing forward or backward. In other embodiments, the button 500 may also be a button with other functions; for example, the button 500 may be the power button of the electronic device 1000. In this case, the user can control the power of the electronic device 1000 using the button 500.

[0066] For example, the electronic device 1000 may further include a first sound-emitting unit 410 and a second sound-emitting unit 420. Both the first sound-emitting unit 410 and the second sound-emitting unit 420 may be mounted on the first housing 110. The first housing 110 may have a first sound outlet 110a and a second sound outlet 110b. The first sound-emitting unit 410 and the second sound-emitting unit 420 may emit sound to the external environment of the electronic device 1000 through the first sound outlet 110a and the second sound outlet 110b, respectively. In other embodiments, the electronic device 1000 may also include other sound-emitting units, and the housing 100 may also have other sound outlets; this application does not specifically limit this.

[0067] For example, the orientation of the first sound outlet 110a may differ from that of the second sound outlet 110b. That is, the first sound outlet 110a and the second sound outlet 110b may be located on different sides of the first housing 110. The opening of the first sound outlet 110a may be positioned away from the first screen 200. The second sound outlet 110b may be located on the top of the first housing 110. The opening of the second sound outlet 110b may be positioned towards the first screen 200. At least a portion of the second sound outlet 110b may be exposed relative to the first screen 200. The first sound outlet 110a may be positioned closer to the button 500 than the second sound outlet 110b. It should be noted that the top of the first housing 110 may be the side of the first housing 110 facing the sky when the electronic device 1000 is in the open state and the user is holding the electronic device 1000 to make a call. Unless otherwise specified below, the top of the first housing 110 can be understood in the same way. In some embodiments, when the electronic device 1000 also includes a second screen, the first sound outlet 110a and the second screen may be located on the same side of the first housing 110.

[0068] Please refer to it again. Figures 1 to 3 When electronic device 1000 is in the on state (e.g.) Figure 2 As shown, the user can interact with the first screen 200. The second sound outlet 110b can be exposed relative to the first screen 200. When the user needs to make a call using the electronic device 1000, the second sound outlet 110b of the electronic device 1000 can be brought close to the ear. At this time, the second sound unit 420 can act as a receiver, and the second sound outlet 110b can act as an inner screen earpiece slit. The second sound unit 420 can play the call audio content to the user through the second sound outlet 110b. In other words, when the electronic device 1000 is in the open state, the call function can be realized through the cooperation of the second sound outlet 110b and the second sound unit 420. In some embodiments, when the second sound unit 420 is working, the first sound unit 410 can also work. At this time, the sound emitted by the first sound unit 410 can cancel out the sound emitted by the second sound unit 420 in the far field, thereby achieving the anti-leakage function when the electronic device 1000 is in the open state, thereby improving the call privacy of the electronic device 1000 and improving the user experience.

[0069] For example, when the electronic device 1000 is in a closed state (e.g. Figure 1As shown, the first screen 200 can be located between the first housing 110 and the second housing 120. In this case, the second sound outlet 110b can be blocked by the first screen 200. When a user needs to make a call using the electronic device 1000, they can bring the first sound outlet 110a of the electronic device 1000 close to their ear. At this time, the first sound unit 410 can act as a receiver, and the first sound outlet 110a can act as an earpiece slit. The first sound unit 410 can play the call audio content to the user through the first sound outlet 110a. In other words, when the electronic device 1000 is in a closed state, the call audio function can be achieved through the cooperation of the first sound outlet 110a and the first sound unit 410.

[0070] Understandably, typical foldable electronic devices only have one earpiece slit, requiring the user to maintain a specific state when making calls. For example, when an electronic device only has an inner screen earpiece slit, the slit is visible when the device is open, allowing the user to make calls. However, when the device is closed, the slit is located inside the device and is obscured by the folded screen, preventing the user from making calls through it. In other words, when an electronic device only has an inner screen earpiece slit, the user needs to keep the device open to make and receive calls, making the process cumbersome and resulting in a poor user experience. In this embodiment, the electronic device 1000 can simultaneously have a first sound outlet 110a and a second sound outlet 110b. The orientation of the first sound outlet 110a differs from that of the second sound outlet 110b. The second sound outlet 110b can serve as the inner screen earpiece slit. When the electronic device 1000 is in the open state, the second audio output port 110b is exposed relative to the first screen 200, allowing the user to make calls using the second audio output port 110b. When the electronic device 1000 is in the closed state, the second audio output port 110b is blocked by the folded first screen 200, while the first audio output port 110a remains exposed. In this case, the user can make calls using the first audio output port 110a. In other words, regardless of whether the electronic device 1000 is in the open or closed state in this embodiment, the user can make calls using the corresponding earpiece opening, resulting in a better user experience.

[0071] Secondly, when the electronic device 1000 is making a call, the first sound unit 410 and the second sound unit 420 can work simultaneously, so that the sound emitted by the first sound unit 410 and the sound emitted by the second sound unit 420 can cancel each other out in the far field, thereby realizing the sound leakage prevention function of the electronic device 1000, thereby improving the call privacy of the electronic device 1000 and improving the user experience.

[0072] In some embodiments, the electronic device 1000 may also be a non-foldable device, that is, the electronic device 1000 may also include only a flat portion (e.g., only the first housing 110).

[0073] The specific structure of the first housing 110 will be described below with reference to the accompanying drawings.

[0074] Figure 4 yes Figure 3 The diagram shows an exploded view of the electronic device 1000 in some embodiments. Figure 5 yes Figure 4 The first middle frame 111 shown is a structural schematic diagram in some embodiments.

[0075] like Figure 4 and Figure 5 As shown, the first housing 110 may include a first middle frame 111 and a first rear cover 112. The second housing 120 may include a second middle frame 121 and a second rear cover 122. Please refer to... Figures 1 to 3 As shown, the folding mechanism 300 can be fixedly connected to the first middle frame 111 and the second middle frame 121. The first middle frame 111 and the second middle frame 121 can be unfolded relative to each other to an open state, or folded relative to each other to a closed state, under the action of the folding mechanism 300. The first screen 200 can be located on the same side of the first middle frame 111 and the second middle frame 121, and is fixedly connected to the first middle frame 111 and the second middle frame 121. The first back cover 112 can be located on the side of the first middle frame 111 facing away from the first screen 200, and is fixedly connected to the first middle frame 111. The second back cover 122 can be located on the side of the second middle frame 121 facing away from the first screen 200, and is fixedly connected to the second middle frame 121. In other embodiments, the first back cover 112 can also be integrally formed with the first middle frame 111, and / or, the second back cover 122 can also be integrally formed with the second middle frame 121.

[0076] For example, the first middle frame 111 may include a middle plate 10 and a side frame 20. The side frame 20 may be fixedly connected to the periphery of the middle plate 10 and together with the middle plate 10 enclose the first mounting space 110c. The side frame 20 may have a first outer peripheral side 20a. The first outer peripheral side 20a may be disposed facing away from the first mounting space 110c.

[0077] For example, the frame 20 may also have a first mounting groove 21. The opening of the first mounting groove 21 may be formed on the first outer peripheral side surface 20a. The first mounting groove 21 may be elongated. The first mounting groove 21 may have an inner peripheral side surface 21b and a groove bottom surface 211. The inner peripheral side surface 21b may be disposed around the groove bottom surface 211.

[0078] Figure 6 yes Figure 4The diagram shows the structure of the first middle frame 111 from another perspective. Figure 7 yes Figure 3 The diagram shows a partial cross-sectional view of one embodiment of the electronic device 1000 cut along point AA. Figure 8 yes Figure 3 The diagram shows a partial cross-sectional view of one embodiment of the electronic device 1000 cut along point BB. It should be noted that... Figure 8 In the accompanying drawings and subsequent sections, the middle plate 10 and the frame 20 are schematically divided by dashed lines.

[0079] like Figures 6 to 8 As shown, the frame 20 may also have a first surface 20b and a second surface 20c disposed opposite to each other along the Z-axis direction. The second surface 20c may be disposed opposite to the first mounting space 110c. Exemplarily, the frame 20 may also have a second mounting groove 22. The second mounting groove 22 may be spaced apart from the first mounting groove 21 in the X-axis direction. The opening of the second mounting groove 22 may be formed on the first surface 20b.

[0080] For example, the frame 20 may also have a second hole 22a. There may be two second holes 22a. The two second holes 22a may be spaced apart along the Y-axis. One end of each second hole 22a may penetrate the bottom surface 211 of the first mounting groove 21, thereby connecting to the first mounting groove 21. The other end of each second hole 22a may connect to the second mounting groove 22. That is, the first mounting groove 21 can be connected to the second mounting groove 22 through the second holes 22a.

[0081] Figure 9 yes Figure 4 The diagram shows a partial assembly structure of the first middle frame 111 and the button 500 in one embodiment. Figure 10 yes Figure 3 The diagram shows a partial cross-sectional view of one embodiment of the electronic device 1000 cut along BB. Figure 11 yes Figure 3 The diagram shows a partial cross-sectional view of one embodiment of the electronic device 1000 cut along point AA.

[0082] like Figures 9 to 11 As shown, at least a portion of the buttons 500 can be mounted in the first mounting groove 21. A portion of the buttons 500 can protrude relative to the first outer peripheral side surface 20a. The buttons 500 can move within the first mounting groove 21 along the width direction of the electronic device 1000 (i.e., the X-axis direction in this embodiment) under the action of an external force. In this case, the first mounting groove 21 can be considered as the travel channel of the buttons 500. In other embodiments, the surface of the button 500 facing away from the bottom surface 211 of the first mounting groove 21 can also be flush with the first outer peripheral side surface 20a.

[0083] For example, the button 500 may include a connected first portion 510 and a second portion 520. The second portion 520 may be positioned closer to the bottom surface 211 of the groove than the first portion 510. There may be two second portions 520. The two second portions 520 may be spaced apart along the Y-axis. For ease of understanding, Figure 11 The first part 510 and the second part 520 are schematically divided by dashed lines.

[0084] Exemplarily, the first portion 510 of the button 500 can contact the inner peripheral side surface 21b of the first mounting groove 21. There may be no gap between the first portion 510 and the inner peripheral side surface 21b of the first mounting groove 21. In this way, the first portion 510 of the button 500 can cooperate with the first housing 110, thereby better sealing the first mounting groove 21 and preventing dust and other debris from entering the first mounting groove 21. The surface of the first portion 510 facing the second portion 520 may be disposed opposite to the bottom surface 211 of the groove. There may be a gap 21c between the surface of the first portion 510 facing the second portion 520 and the bottom surface 211 of the groove. The gap 21c may constitute at least a portion of the first mounting groove 21. In other embodiments, due to assembly / dimensional tolerances, there may also be a small gap between the first portion 510 of the button 500 and the inner peripheral side surface 21b of the first mounting groove 21.

[0085] For example, the two second portions 520 can be positioned one-to-one opposite the two second holes 22a. Taking one of the second portions 520 as an example, the second portion 520 is spaced apart from the inner peripheral side 21b of the first mounting groove 21. When the user presses the button 500, the first portion 510 can drive the second portion 520 to move in the direction toward the bottom surface 211 of the first mounting groove 21. At this time, part of the second portion 520 can be located within the second hole 22a.

[0086] For example, the electronic device 1000 may further include guide rods (not shown) and circuit components (not shown). The circuit components can be installed within the second mounting slot 22. The circuit components can be electrically connected to the motherboard (not shown) of the electronic device 1000. There can be two guide rods. The two guide rods can pass through two second holes 22a respectively. One end of each guide rod can be fixedly connected to the surfaces of the two second portions 520 of the button 500 facing away from the first portion 510. The other ends of both guide rods can be fixedly connected to the circuit components. When a user presses the button 500, the button 500 can move towards the bottom surface 211 of the first mounting slot 21 under external force, driving the guide rods to move, thereby triggering the corresponding button on the circuit component. This allows the circuit component to transmit electrical signals to the motherboard, thereby adjusting the volume of the electronic device 1000 and realizing the sound control function of the button 500. When button 500 actuates the corresponding button on the guide rod trigger circuit assembly, the first part 510 of button 500 can still be spaced apart from the bottom surface 211 of the first mounting groove 21. That is, regardless of whether the user presses button 500, there can be a gap 21c between the first part 510 of button 500 and the bottom surface 211 of the first mounting groove 21.

[0087] like Figure 10 and Figure 11 As shown, the frame 20 may also have a sound outlet groove 24. The opening of the sound outlet groove 24 may be formed on the first surface 20b of the frame 20. The sound outlet groove 24 may be spaced apart from the first mounting groove 21 and the second mounting groove 22. Exemplarily, at least a portion of the sound outlet groove 24 may be spaced apart from the first mounting groove 21 in the Z-axis direction.

[0088] For example, the frame 20 may also have a first hole 21a ( Figure 6 The specific structure of the first hole 21a is also illustrated in the diagram. The first hole 21a can be positioned directly opposite the gap 21c. There can be multiple first holes 21a. Each of the multiple first holes 21a can be a uniformly arranged small hole. One end of each of the multiple first holes 21a can penetrate the inner peripheral side 21b of the first mounting groove 21, thereby connecting to the gap 21c. The other end of each of the multiple first holes 21a can connect to the sound groove 24. In this case, the gap 21c can connect to the sound groove 24 through the first holes 21a. In other embodiments, the shape, position, and arrangement of the first hole 21a can also be other forms. It should be noted that... Figure 6 The first hole 21a is schematically outlined with dashed lines in the accompanying drawings and subsequent parts.

[0089] For example, the middle plate 10 may have a first surface 10a and a second surface 10b disposed opposite to each other along its thickness direction. The first surface 10a may be disposed toward the first mounting space 110c. The middle plate 10 may also have a clearance groove 11. The opening of the clearance groove 11 may be formed on the first surface 10a of the middle plate 10.

[0090] For example, the first housing 110 may also have a connecting conduit 110d. The connecting conduit 110d may be spaced apart from the second mounting groove 22. One end of the connecting conduit 110d may be connected to the clearance groove 11, and the other end may be connected to the gap 21c. In this case, the clearance groove 11 may be connected to the sound outlet groove 24 in sequence through the connecting conduit 110d, the gap 21c, and the first hole 21a.

[0091] For example, the frame 20 may have a first channel 23. The middle plate 10 may have a second channel 12. One end of the second channel 12 may connect to the clearance groove 11, and the other end may connect to the first channel 23. The end of the first channel 23 facing away from the second channel 12 may connect to the gap 21c. In this case, the first channel 23 and the second channel 12 may together form a connecting pipe 110d. The first channel 23 may be spaced apart from the second mounting groove 22. In other embodiments, the electronic device 1000 may also include an enclosure. The enclosure may be fixed to the middle plate 10 of the first housing 110 and enclose the second channel 12 with the middle plate 10.

[0092] In some embodiments, the frame 20 may not have a sound outlet groove 24. In this case, one end of the first hole 21a can penetrate the inner peripheral side 21b of the first mounting groove 21, and the other end can penetrate the first surface 20b of the frame 20. The gap 21c can communicate with the external space of the first housing 110 through the first hole 21a.

[0093] Figure 12 yes Figure 3 The diagram shows a partial cross-sectional view of one embodiment of the electronic device 1000 cut along point AA.

[0094] like Figures 10 to 12 As shown, the first back cover 112 can be located on the side of the first surface 10a of the middle plate 10 facing away from the second surface 10b, and can be fixedly connected to the first middle frame 111. At this time, the first mounting space 110c can be located between the first back cover 112 and the middle plate 10. The first back cover 112 can cover the first mounting space 110c. A portion of the first screen 200 can be located on the side of the second surface 10b of the middle plate 10 facing away from the first surface 10a, and can be fixedly connected to the first middle frame 111.

[0095] For example, the first sound outlet 110a may be formed on the first rear cover 112. The first sound outlet 110a may be spaced apart from the first mounting groove 21 along the thickness direction of the first housing 110 (i.e., the Z-axis direction in this embodiment). In other embodiments, the first sound outlet 110a may also be formed on the first middle frame 111. In some other embodiments, the first sound outlet 110a may also be formed on both the first rear cover 112 and the first middle frame 111.

[0096] For example, the first rear cover 112 can cover the sound outlet groove 24 and the second mounting groove 22. The sound outlet groove 24 can connect to the first sound outlet 110a. The second mounting groove 22 can be isolated from the first sound outlet 110a. The sound outlet groove 24 can connect to the external space of the first housing 110 through the first sound outlet 110a. The clearance groove 11 can connect to the external space of the first housing 110 by sequentially passing through the connecting pipe 110d, the gap 21c, the first hole 21a, the sound outlet groove 24, and the first sound outlet 110a.

[0097] Figure 13 yes Figure 4 The diagram shows an assembly structure of the electronic device 1000 in one embodiment. Figure 14 yes Figure 3 The diagram shows a partial cross-sectional view of one embodiment of the electronic device 1000 cut along the CC direction. For ease of understanding, Figure 13 The structure of the first screen 200 and the first back cover 112 is hidden.

[0098] like Figure 13 and Figure 14 As shown, the first sound-emitting unit 410 and the second sound-emitting unit 420 (please refer to...) Figure 3 All of the above (as shown) can be located in the first mounting space 110c of the first housing 110 and can be fixedly connected to the first housing 110. Exemplarily, the first sound-emitting unit 410 can be fixedly connected to the first surface 10a of the middle plate 10. The first sound-emitting unit 410 can be disposed directly opposite the relief groove 11. The first sound-emitting unit 410 and the relief groove 11 can together enclose the sound-emitting space 410a. The relief groove 11 can constitute at least a portion of the sound-emitting space 410a. In other embodiments, the first sound-emitting unit 410 may also have a sound-emitting space 410a.

[0099] For example, the second channel 12 can connect the sound-emitting space 410a and the first channel 23 (see in conjunction with...). Figure 10 (As shown). The sound-emitting space 410a can be connected to the external space of the first housing 110 by sequentially passing through the connecting pipe 110d, the gap 21c, the first hole 21a, the sound outlet groove 24 and the first sound outlet 110a.

[0100] For example, the first sound-generating unit 410 may include a first diaphragm 411. At least a portion of the first diaphragm 411 may be exposed relative to the sound-generating space 410a. In this case, the first sound-generating unit 410 may emit sound using the sound-generating space 410a. The sound-generating space 410a can be considered as at least a portion of the front cavity of the first sound-generating unit 410. In other embodiments, the first middle frame 111 may not have the clearance groove 11. The electronic device may also include a support member. The support member may be fixed to the middle plate 10 of the first middle frame 111. The first sound-generating unit 410 may be fixed to the side of the support member facing away from the middle plate 10. The support member may be used to support the first sound-generating unit 410. In this case, the support member, the middle plate 10, and the first sound-generating unit 410 may together enclose the sound-generating space 410a.

[0101] Please combine Figure 12 As shown, when the first sound-emitting unit 410 is working, the first diaphragm 411 can push the air in the sound-emitting space 410a, through the connecting pipe 110d, the gap 21c, the first hole 21a, and the sound outlet groove 24 in sequence, and then emit sound to the external space of the electronic device 1000 through the first sound outlet 110a. The connecting pipe 110d, the gap 21c, the first hole 21a, and the sound outlet groove 24 together constitute the sound outlet pipe 600 of the electronic device 1000. That is, the first sound-emitting unit 410 can emit sound to the external space of the electronic device 1000 through the sound-emitting space 410a, the sound outlet pipe 600, and the first sound outlet 110a in sequence. At this time, the sound-emitting space 410a and the sound outlet pipe 600 together constitute the front cavity of the first sound-emitting unit 410.

[0102] Understandably, conventional electronic devices typically hollow out part of their casing to form a sound outlet for the sound-generating unit. However, this reduces the structural strength of the casing, making it more susceptible to damage from external forces and thus shortening the lifespan of the electronic device. In this embodiment, the electronic device 1000 incorporates the first mounting slot 21 for mounting the button 500 as part of the sound outlet 600 of the first sound-generating unit 410. Thus, the first mounting slot 21 serves two purposes: firstly, it accommodates the button 500 and acts as a travel channel for the button 500; secondly, the first sound-generating unit 410 can utilize the gap 21c within the first mounting slot 21 to generate sound. In other words, the button 500 and the sound outlet 600 reuse the space of the first mounting slot 21, thereby reducing the space required for the casing 100 to form the sound outlet 600 and for mounting the button 500 and related components. This ensures the structural strength of the casing 100 and contributes to extending the lifespan of the electronic device 1000. In other words, the electronic device 1000 in this embodiment can improve the structural strength of the electronic device 1000 while ensuring the sound output effect of the electronic device 1000.

[0103] Secondly, compared to electronic devices that connect to the second mounting slot via a connecting pipe, the first sound-emitting unit requires space including the first space, the connecting pipe, the second mounting slot, the second hole, and the gap to emit sound. When the user presses a button to adjust the volume, some buttons may cover the second hole, preventing the sound emitted by the first sound-emitting unit from being transmitted through the second hole to the gap in the first mounting slot, thus affecting the sound output of the first sound-emitting unit and consequently the sound output of the electronic device. In this embodiment, the connecting pipe 110d of the electronic device 1000 can be spaced apart from the second mounting slot 22. The connecting pipe 110d can directly connect the gap 21c and the sound-emitting space 410a. Thus, when the first sound-emitting unit 410 is working, even if the user presses the button 500 to close the second hole 22a, the first sound-emitting unit 410 can still use the sound-emitting space 410a, the connecting pipe 110d, the gap 21c, the first hole 21a, the sound outlet 24, and the first sound outlet 110a to emit sound to the external space of the electronic device 1000, thereby ensuring the sound output stability of the electronic device 1000 and improving the user experience.

[0104] Furthermore, in this embodiment, the first mounting groove 21 and the first sound outlet 110a can be arranged at intervals along the thickness direction of the first housing 110 (i.e., the Z-axis direction in this embodiment). On the one hand, the distance between the first mounting groove 21 and the first sound outlet 110a is relatively short, resulting in less space occupied by the first hole 21a. This reduces the amount of hollowed-out portion in the first housing 110, allowing for a larger volume of solid material in the first housing 110, thus ensuring sufficient structural strength and improving the service life of the electronic device 1000. On the other hand, the first mounting groove 21 and the first sound outlet 110a can share the same space on the plane containing the length and width directions of the electronic device 1000 (i.e., the plane containing the X-axis and Y-axis directions in this embodiment). This helps save space in the electronic device 1000.

[0105] Furthermore, compared to electronic devices with only one first hole, to ensure sound can travel from the first mounting slot through the first hole to the first sound outlet, the first hole is typically designed as a large through-hole. However, a large opening area for the first hole results in less solid material in the first housing, reducing its structural strength and making it more susceptible to damage from external forces, thus affecting the lifespan of the electronic device. In this embodiment, the electronic device 1000 can have multiple first holes 21a, which can be spaced apart. This reduces the opening area of ​​the first housing 110, allowing it to have sufficient solid material, thereby ensuring sufficient structural strength and improving the lifespan of the electronic device 1000.

[0106] Furthermore, in this embodiment, the multiple first holes 21a in the electronic device 1000 are evenly arranged. Thus, when the first sound-emitting unit 410 operates, sound can propagate relatively evenly from the gap 21c to the sound outlet 24 and the first sound outlet 110a, and then to the external space of the electronic device 1000. At this time, the sound output of the electronic device 1000 is relatively uniform, and the sound output effect of the electronic device 1000 is better.

[0107] In some embodiments, the electronic device 1000 may further include a dust filter (not shown). The dust filter may be located within the sound outlet 24. The dust filter may be fixedly connected to the first middle frame 111 and / or the first rear cover 112. The dust filter may cover the first sound outlet 110a. At least a portion of the dust filter may be exposed relative to the first sound outlet 110a. In this way, the dust filter can prevent dust or other debris from entering the first sound outlet 110a, thereby preventing the first sound outlet 110a from being blocked, and thus improving the sound output stability of the electronic device 1000.

[0108] In some embodiments, the electronic device 1000 may further include a controller, a first power amplifier, and a second power amplifier. The controller, the first power amplifier, and the second power amplifier may all be located in the first mounting space 110c. Both the first and second power amplifiers may be electrically connected to the controller. The first and second power amplifiers may be electrically connected one-to-one to the first sound-emitting unit 410 and the second sound-emitting unit 420. The controller may transmit a first signal and a second signal to the first sound-emitting unit 410 and the second sound-emitting unit 420, respectively. This allows for independent control of the first sound-emitting unit 410 and the second sound-emitting unit 420. The electronic device 1000 can control the first and second signals through the controller, thereby controlling the operating state of the first sound-emitting unit 410 and the second sound-emitting unit 420, and thus meeting different usage scenarios and requirements.

[0109] In some embodiments, the second housing 120 may further have a second mounting space, and a second sound outlet 110b may be formed in the second housing 120, the second sound outlet 110b being able to communicate with the second mounting space and the external space of the second housing 120. The second sound-emitting unit 420 may be fixed to the second housing 120. The second sound-emitting unit 420 may emit sound to the external environment of the electronic device 1000 through the second sound outlet 110b.
