electronic devices

[0001] This application claims priority to Chinese Patent Application No. 202510123937.6, filed 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 audio technology, specifically to an electronic device. Background Technology

[0003] Nowadays, electronic devices (such as mobile phones and tablets) are becoming increasingly waterproof. To meet waterproof requirements, electronic devices need to be fully sealed. However, after sealing, a closed cavity is formed inside the electronic device. If the external environment changes, the pressure inside the electronic device cannot be released. Therefore, a balancing valve is needed to release the pressure.

[0004] However, since the balance valve is located inside the electronic device, it needs to be connected to the outside through a corresponding airflow channel. The airflow channel will create a balance hole on the outer surface of the electronic device, affecting its appearance. Summary of the Invention

[0005] This application provides an electronic device. The electronic device includes a first cover plate, a middle frame, a second cover plate, a first speaker, and a first waterproof and breathable valve. Through the design of the middle frame, the first speaker, and the first waterproof and breathable valve, the inner cavity of the electronic device can be connected to the first sound outlet channel of the first speaker. The first waterproof and breathable valve can be set at the connection point to act as a balance valve, thereby using the first sound outlet channel for pressure relief and balance, reducing the need for balance holes and improving the appearance of the electronic device.

[0006] In a first aspect, this application provides an electronic device, which includes a first cover plate, a middle frame, a second cover plate, a first speaker, and a first waterproof and breathable valve; the first cover plate and the second cover plate are installed on opposite sides of the middle frame, and the first cover plate and the second cover plate form an inner cavity of the electronic device; the first speaker is installed on the middle frame, the middle frame has a first sound outlet channel, the first sound outlet channel connects the top side space of the first speaker to the outside of the electronic device; the middle frame is provided with a first connecting hole, the first connecting hole connects the inner cavity of the electronic device and the first sound outlet channel; the first waterproof and breathable valve is disposed at the first connecting hole and covers the first connecting hole.

[0007] In this application, the design of the first connecting hole allows for communication between the internal cavity and the external environment of the electronic device, achieving pressure balance between the inside and outside of the device and thus providing pressure relief. A first waterproof and breathable valve is located at the first connecting hole, ensuring the exchange of airflow between the inside and outside of the electronic device while preventing external moisture and impurities from entering, thus providing dust and moisture protection. This first waterproof and breathable valve can also be called a balance valve. Since the internal cavity of the electronic device can be depressurized through the first connecting hole and the first sound outlet, pressure balance can be achieved using the first sound outlet, eliminating the need for a separate balance port. This shortens the channel length required for internal pressure relief and reduces the need for a separate balance port, allowing for a concealed balance port design, improving the appearance and sophistication of the electronic device.

[0008] In some possible implementations, the first cover plate and the middle frame enclose a first space, the second cover plate and the middle frame enclose a second space, and the middle frame is also provided with a second connecting hole, which connects the first space and the second space; the first connecting hole connects the first space and the first sound outlet channel, or the first connecting hole connects the second space and the first sound outlet channel.

[0009] In this implementation, the space on both sides of the middle frame can be connected by the second connecting hole, so that the space on both sides of the middle frame can be depressurized by the first sound outlet channel, thereby achieving air pressure balance, which is beneficial to the stability of the internal air pressure of the electronic device.

[0010] In some possible implementations, the mid-frame is also provided with a first mounting groove, the opening of which faces the first cover plate or the second cover plate; the electronic device also includes a sound cavity shell, which is installed in the first mounting groove, a first speaker is installed in the sound cavity shell, the first speaker and the inner wall of the sound cavity shell surround to form a first front cavity, and a first sound outlet channel connects the first front cavity to the outside of the electronic device.

[0011] In this implementation, since the third wall is provided with a limiting rib, the first speaker can be installed on the limiting rib. At the same time, the limiting rib is arranged around the first sound outlet surface to separate the first front cavity formed between the first sound outlet surface and the third wall from the space next to the limiting rib, which is beneficial to the sound output effect of the first speaker.

[0012] In some possible implementations, the first sound outlet channel penetrates the end face of the middle frame and the inner wall of the first mounting groove, the first sound outlet channel forms a first sound outlet on the end face of the middle frame, and the first sound outlet channel forms a first opening on the inner wall of the first mounting groove; the sound cavity shell includes a first wall facing the first opening, the first wall abuts against the inner wall of the first mounting groove, the first wall is provided with a first through hole, and the first through hole connects the first front cavity and the first sound outlet channel.

[0013] In this implementation, the first through hole enables the first front cavity to be connected to the outside of the acoustic cavity shell, so that the first speaker can emit sound to the outside of the acoustic cavity shell in sequence through the first front cavity and the first through hole.

[0014] In some possible implementations, the acoustic cavity shell also includes a second wall and a third wall disposed opposite to each other, with the first wall connected between the second wall and the third wall; the first loudspeaker is mounted on the second wall, with the first sound-emitting surface of the first loudspeaker facing the third wall, and the first sound-emitting surface and the third wall are spaced apart to form a first front cavity; the first connecting hole penetrates the bottom wall of the first mounting groove, and the third wall is provided with a second through hole, which is disposed opposite to the first connecting hole and connects the first connecting hole and the first front cavity.

[0015] In this implementation, the first connecting hole can connect the first space and the first front cavity, so that the internal cavity of the electronic device can be depressurized through the first connecting hole, the second through hole, the first front cavity, the first through hole, and the first sound outlet channel.

[0016] In some possible implementations, the first waterproof and breathable valve is disposed between the third wall and the bottom wall of the first mounting groove, and the first waterproof and breathable valve also covers the second through hole.

[0017] In this implementation, the first waterproof and breathable valve is positioned between the third wall and the bottom wall of the first mounting groove, which helps improve the airtightness of the connection between the first connecting hole and the second through hole. Because the first waterproof and breathable valve is positioned between the third wall of the acoustic cavity shell and the bottom wall of the first mounting groove, it improves the installation stability of the first waterproof and breathable valve, thereby improving the airtightness between the first connecting hole and the second through hole. This allows for pressure relief within the electronic device's cavity while also preventing external moisture and impurities from entering the electronic device's cavity.

[0018] In some possible implementations, the first waterproof and breathable valve includes a first foam and a first waterproof and breathable membrane. The first foam is connected to the periphery of the first waterproof and breathable membrane. The first waterproof and breathable membrane covers the second through hole and the first connecting hole. The first foam abuts against the third wall and the bottom wall of the first mounting groove. The first foam is in a compressed state.

[0019] In this implementation, the first foam allows the speaker module and the middle frame to be pressed together at the bottom wall of the first mounting groove, so that the first foam can seal the outer periphery of the connection between the first through hole and the second through hole, thereby improving the airtightness at this point.

[0020] In some possible implementations, the electronic device also includes a second waterproof and breathable valve disposed on the first wall, which covers the first through hole.

[0021] In this implementation, the second waterproof and breathable valve can cover the first through hole, so as to prevent water vapor and impurities from entering the first through hole while ensuring that air can pass through it. Due to the setting of the second waterproof and breathable valve, while preventing water vapor and impurities from entering the first front cavity, it also ensures that the first speaker can emit sound through the second waterproof and breathable valve.

[0022] The second waterproof and breathable membrane can cover the first through hole and the first opening, the second foam abuts against the first wall and the inner wall of the first mounting groove, and the second foam is in a compressed state.

[0023] In this implementation, the second foam allows the speaker module and the middle frame to be pressed tightly against the inner wall of the first mounting groove. This seals the outer periphery of the first opening and the first through hole, improving airtightness and preventing external moisture and impurities from entering. It also enhances the sound output of the first speaker. Furthermore, the second waterproof and breathable membrane prevents external moisture and impurities from entering the first front cavity through the first sound outlet channel, while ensuring unobstructed sound output between the first front cavity and the first sound outlet channel, further improving sound quality.

[0024] In some possible implementations, the first connecting hole penetrates the side wall of the first sound outlet channel and connects to the first sound outlet channel, and the first waterproof and breathable valve is located at the end of the first connecting hole away from the first sound outlet channel and covers the first connecting hole.

[0025] In this implementation, the first connecting hole can be directly connected to the first sound output channel, so that the internal cavity of the electronic device can be depressurized through the first connecting hole and the first sound output channel in sequence. The depressurization path is short, which is beneficial to ensuring the airtightness of the depressurization path.

[0026] The first connecting hole can penetrate the inner wall of the second sub-hole of the first sound outlet channel and communicate with the second sub-hole.

[0027] In this implementation, since the second sub-hole is farther from the end face of the mid-frame than the first sub-hole, and the first connecting hole penetrates the inner wall of the second sub-hole, it avoids the first connecting hole being too close to the end face of the mid-frame, which would result in the mid-frame having an excessively thin wall thickness at the first connecting hole, thus ensuring the structural strength of the mid-frame in the area where the first connecting hole is located. Furthermore, since the extension direction of the second sub-hole is different from that of the first sub-hole, and the first connecting hole penetrates the inner wall of the second sub-hole, it prevents the first connecting hole from being directly visible from the first sound outlet, which is beneficial for improving the appearance of the electronic device.

[0028] In some possible implementations, the first sound output channel includes a first sub-hole and a second sub-hole that are connected, with the extension direction of the second sub-hole intersecting the extension direction of the first sub-hole; the first connecting hole penetrates the inner wall of the second sub-hole and is connected to the second sub-hole.

[0029] In this implementation, setting the extension direction of the first sub-hole to be parallel to the first direction X facilitates the processing of the first sub-hole and allows the first sound outlet to form a regular shape, improving the appearance of the electronic device. Setting the extension direction of the second sub-hole to be different from that of the first sub-hole allows for adjustment of the position of the first opening on the inner wall of the first mounting slot to match the position of the first through hole on the sound cavity shell, thus facilitating the installation of the speaker module in the first mounting slot. Furthermore, this design also helps to ensure that the first sound outlet is located in the center region of the end face of the mid-frame in the thickness direction, further improving the appearance of the electronic device on the end face of the mid-frame.

[0030] In some possible implementations, the electronic device also includes a first microphone mounted on the mid-frame and spaced apart from the first speaker; the mid-frame also has a first pickup channel that connects the top side space of the first microphone with the internal space of the electronic device.

[0031] In this implementation, the structure of the first pickup channel is decoupled from the structures of the first cover plate and the second cover plate. As long as the first pickup channel can connect the top side space of the first microphone with the outside of the electronic device, and the first pickup port can form an appearance design and arrangement pattern consistent with the first sound outlet, it is acceptable.

[0032] The first pickup channel may include a third sub-hole, a fourth sub-hole, and a fifth sub-hole. The third sub-hole forms a first pickup hole on the end face of the middle frame. The fifth sub-hole forms a second opening in the second part of the bottom wall of the first mounting groove. The fourth sub-hole connects the third sub-hole and the fifth sub-hole. The extension direction of the third sub-hole is the same as that of the first sub-hole, while the extension direction of the fourth sub-hole is different from that of the third sub-hole.

[0033] In this implementation, the position of the third sub-hole is changed by setting the fourth sub-hole, so that the first pickup port formed by the third sub-hole on the end face of the middle frame can be arranged at equal intervals with multiple first sound outlets. At the same time, by setting the extension direction of the third sub-hole to be consistent with the extension direction of the first sub-hole, it is beneficial to make the shape of the first pickup port consistent with that of the first sound outlet.

[0034] The extension direction of the fifth sub-hole may differ from the extension direction of the fourth sub-hole and also from the extension direction of the third sub-hole.

[0035] In this implementation, the design of the extension direction of the third, fourth and fifth sub-holes can take into account both the installation position of the first microphone and the position of the first pickup port. This not only reduces the extra space occupied by the first microphone, but also ensures that the design of the first pickup port is consistent with the design of the first sound outlet, thereby improving the appearance of the electronic device.

[0036] In some possible implementations, the first sound outlet channel forms a first sound outlet on the end face of the middle frame, and the first pickup channel forms a first pickup outlet on the end face of the middle frame; there are multiple first sound outlets, and the multiple first sound outlets have the same shape, and the shape of the first pickup outlet is the same as the shape of the first sound outlet.

[0037] In this implementation, the multiple first sound outlets have the same shape, so that the appearance of the multiple first sound outlets is consistent, which helps to improve the appearance of the electronic device. The shape of the first pickup port can be the same as the shape of the first sound outlet, so that the shape of the first sound outlet is consistent with the shape of the first pickup port, thereby improving the appearance of the electronic device at the first end.

[0038] In some possible implementations, multiple first sound outlets are arranged at equal intervals, and first pickup ports are arranged on one side of the multiple first sound outlets. The distance between the first pickup port and the first sound outlet is equal to the distance between two adjacent first sound outlets.

[0039] In this implementation, multiple first sound outlets can be arranged at equal intervals along the second direction Y to improve the appearance of the first sound outlets, thereby improving the appearance of the electronic device. The distance between the first pickup port and the first sound outlet is equal to the distance between two adjacent first sound outlets, so that the openings on the end face of the middle frame at the first end have the same shape and are arranged at equal intervals, which is beneficial to the harmonious and unified appearance.

[0040] In some possible implementations, the electronic device has a first end and a second end that are arranged opposite to each other, the line connecting the first end and the second end being perpendicular to the thickness direction of the electronic device, and a first speaker is disposed at the first end; the electronic device also includes a second speaker and a second microphone, both of which are located at the second end and are mounted on the middle frame, with the second speaker and the second microphone spaced apart; the middle frame and the first cover plate or the second cover plate form an opening at the second end, and the electronic device is provided with a second sound output channel and a second sound pickup channel, the second sound output channel connecting the opening and the top space of the second speaker, and the second sound pickup channel connecting the opening and the top space of the second microphone.

[0041] In this method of realizing love, the slit design allows the second speaker's sound output and the second microphone's sound pickup to share the same slit, reducing the structural design of the sound output and sound pickup. This helps to ensure the integrity of the electronic device's appearance and also improves the consistency of the electronic device's appearance, making the electronic device more aesthetically pleasing and enhancing its sophistication.

[0042] In some possible implementations, the middle frame is further provided with a first slot, a second mounting slot, and a fourth connecting hole. The first slot, the second mounting slot, and the fourth connecting hole are located at the second end. The opening orientation of the first slot is opposite to the opening orientation of the second mounting slot. The fourth connecting hole penetrates the bottom wall of the first slot and the bottom wall of the second mounting slot, and connects the first slot and the second mounting slot. The second speaker is mounted in the second mounting slot. The second sound output surface of the second speaker faces the bottom wall of the second mounting slot and covers the fourth connecting hole. The electronic device is arranged on one side of the second sound output surface to form a second sound output channel.

[0043] In this implementation, the first cover plate, the middle frame, and the sealing element form a second sound outlet channel. The second sound outlet channel includes a channel formed by the first cover plate, the middle frame, and the sealing element at the first slot, and a fourth connecting hole, so that the second sound outlet channel can connect the top side space of the second speaker and the opening, thereby realizing the sound output of the second speaker.

[0044] In some possible implementations, the middle frame is also provided with a second slot and a fifth connecting hole. The opening of the second slot faces the same direction as the first slot. The second slot is located at the second end and is spaced apart from the first slot. The fifth connecting hole penetrates the bottom wall of the second slot. The second microphone is located on the other side of the middle frame opposite to where the second slot is located. The second pickup surface of the second microphone faces the fifth connecting hole and covers the fifth connecting hole. The electronic device is arranged on one side of the second pickup surface to form a second pickup channel.

[0045] In this implementation, the first cover plate, the middle frame, the shielding member, and the sealing member surround and form a second sound pickup channel. The second sound pickup channel includes the first cover plate, the middle frame, the shielding member, and the sealing member surrounding and forming a channel at the second slot, and a fifth connecting hole, so that the second sound pickup channel can connect the top side space of the second microphone and the slot, thereby realizing the sound pickup of the second microphone.

[0046] In some possible implementations, the second slot includes a first sub-slot and a second sub-slot, the size of the first sub-slot is larger than the size of the second sub-slot, and the second sub-slot is recessed in the bottom wall of the first sub-slot; a portion of the fifth connecting hole penetrates the bottom wall of the first sub-slot, and another portion penetrates the bottom wall of the second sub-slot; the electronic device also includes a shielding member, which is disposed in the first sub-slot and shields a portion of the second sub-slot.

[0047] In this implementation, the blocking component can guide the sound pickup of the second microphone, preventing the opening of the second connecting hole at the second slot from being too large, which is beneficial to improving the sound pickup effect of the second microphone.

[0048] In some possible implementations, the electronic device also includes a seal disposed in the mid-frame, the seal being along the periphery of the first slot and covering a portion of the second slot.

[0049] In this implementation, the sealing element improves the airtightness between the middle frame and the first cover plate, thereby enhancing the airtightness of the second sound outlet channel and improving the sound output performance of the second speaker. Similarly, the sealing element also improves the airtightness of the second sound pickup channel, thus enhancing the sound pickup performance of the second microphone. Attached Figure Description

Thus, a feature defined with "first," "second," "third," and "fourth" may explicitly or implicitly include one or more of that feature.

[0086] Please refer to Figures 1A and 1B. Figure 1A is a structural schematic diagram of an electronic device 1000 provided in an embodiment of this application; Figure 1B is a structural schematic diagram of the electronic device 1000 shown in Figure 1A from another perspective.

[0087] In some embodiments, the electronic device 1000 can be a candybar phone, a foldable phone, a tablet computer, a multimedia player, headphones, a laptop computer, an in-vehicle device, a foldable terminal device, a television, or a wearable device, etc., that has a sound pickup function. Wearable devices can be smart bracelets, smartwatches, smart headsets, smart glasses, etc. The electronic device 1000 in the embodiment shown in Figure 1A is illustrated using a candybar phone as an example. Of course, other types of electronic devices 1000 can also adopt similar structures, which will not be elaborated further below.

[0088] For example, the electronic device 1000 may include a first cover plate 10, a second cover plate 20, and a middle frame 30. The first cover plate 10 and the second cover plate 20 may be mounted on opposite sides of the middle frame 30. An internal cavity of the electronic device 1000 may be formed between the first cover plate 10 and the second cover plate 20.

[0089] The first cover plate 10 can be a screen, and the second cover plate 20 can be a back cover (i.e., a battery cover). The first cover plate 10 can be a flexible display screen or a rigid display screen. The first cover plate 10 can be an organic light-emitting diode (OLED) display screen, a mini organic light-emitting diode (MLED) display screen, a micro organic light-emitting diode (MLED) display screen, a quantum dot light-emitting diode (QLED) display screen, a liquid crystal display (LCD), etc. The second cover plate 20 is used to protect the internal electronic components of the electronic device 1000.

[0090] In some other embodiments, the first cover plate 10 can be a back cover and the second cover plate 20 can be a screen, which is not limited here. In the embodiments of this application, the first cover plate 10 is used as a screen and the second cover plate 20 is used as a back cover for illustration.

[0091] In some embodiments, the electronic device 1000 may further include multiple components (not shown in the figures) mounted within the cavity of the electronic device 1000. 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 pickup device, a headphone jack, a sensor module, buttons, a motor, an indicator, and a subscriber identification module (SIM) card interface, etc.

[0092] The electronic device 1000 can implement audio functions, such as music playback and recording, through an audio module, speaker, receiver, pickup device, headphone jack, and processor.

[0093] The audio module is used to convert digital audio information into analog audio signals for output, and also to convert analog audio input into digital audio signals. The audio module can also be used for encoding and decoding audio signals. In some embodiments, the audio module may be located within the processor, or some functional modules of the audio module may be located within the processor.

[0094] A loudspeaker, also known as a "speaker," is used to convert audio electrical signals into sound signals. Electronic devices 1000 can listen to music or make hands-free calls through loudspeakers.

[0095] A receiver, also known as a "handpiece," is used to convert audio electrical signals into sound signals. When an electronic device answers a phone call or voice message, the receiver can be brought close to the listener's ear to hear the voice.

[0096] A sound pickup device, also known as a microphone, transceiver, or voice recorder, is used to convert sound signals into electrical signals. When making a phone call or sending a voice message, the user can speak by bringing their mouth close to the pickup device, inputting the sound signal into the device. Electronic device 1000 may have at least one sound pickup device. In some embodiments, electronic device 1000 may have two sound pickup devices, which, in addition to collecting sound signals, can also perform noise reduction. In other embodiments, electronic device 1000 may also have three, four, or more sound pickup devices, enabling sound signal collection, noise reduction, sound source identification, and directional recording, among other functions.

[0097] It should be noted that Figures 1A and 1B only schematically show some components of the electronic device 1000, and the actual shape and size of these components are not limited by Figures 1A, 1B, and the following figures. It should be understood that when the electronic device 1000 is in other forms, the electronic device 1000 may not include the first cover plate 10, or the electronic device 1000 may include multiple first cover plates 10.

[0098] For ease of description, a coordinate system is defined, with the length direction of the electronic device 1000 shown in Figure 1A as the first direction X, the width direction as the second direction Y, and the thickness direction as the third direction Z. It should be noted that the first direction X, the second direction Y, and the third direction Z are used to facilitate illustrating the attitude and relative position of the various components of the electronic device 1000 in different figures, and do not limit the attitude and position of the various components of the electronic device 1000. In some examples, any two of the first direction X, the second direction Y, and the third direction Z intersect each other (e.g., are perpendicular). The following explanation uses the example of any two of the first direction X, the second direction Y, and the third direction Z being perpendicular to each other, thus forming a three-dimensional Cartesian coordinate system. It is understood that in other embodiments, the axes of the coordinate system can be defined in other ways, which are not limited here.

[0099] Please refer to Figures 1A and 2. Figure 2 is a partial structural exploded view of the electronic device 1000 shown in Figure 1B in some embodiments.

[0100] In some embodiments, the electronic device 1000 may further include a speaker module 40, a first waterproof and breathable valve 50, a first microphone 60, a first sealing ring 70, a second speaker 80, a second microphone 90, a second sealing ring 100, a shielding member 110, and a sealing member 120. The speaker module 40, the first waterproof and breathable valve 50, the first microphone 60, the first sealing ring 70, the second speaker 80, the second microphone 90, the second sealing ring 100, the shielding member 110, and the sealing member 120 may all be mounted on the middle frame 30.

[0101] For example, the electronic device 1000 may include a first end 130 and a second end 140 disposed opposite to each other. The direction of the line connecting the first end 130 and the second end 140 may be parallel to a first direction X.

[0102] The speaker module 40, the first waterproof and breathable valve 50, the first microphone 60, and the first sealing ring 70 can be located at the first end 130. The speaker module 40 is used for sound output from the electronic device 1000 at the first end 130. The first waterproof and breathable valve 50 is used for waterproofing and ventilating the electronic device 1000 at the first end 130. The first microphone 60 is used for sound pickup by the electronic device 1000 at the first end 130. The first sealing ring 70 is used for sealing the first microphone 60 and the middle frame 30.

[0103] The speaker module can be spaced apart from the first microphone 60.

[0104] The second speaker 80, second microphone 90, second sealing ring 100, shielding member 110, and sealing member 120 can be located at the second end 140. The second speaker 80 can be used for sound output from the electronic device 1000 at the second end 140. The second microphone 90 can be used for sound pickup by the electronic device 1000 at the second end 140. The second sealing ring 100 can be used for sealing the second microphone 90 and the middle frame 30. The shielding member 110 can be used to adjust the sound pickup path of the second microphone 90. The sealing member 120 can be used to seal the sound output path of the second speaker 80 and the sound pickup path of the second microphone 90.

[0105] The second speaker 80 can be spaced apart from the second microphone 90.

[0106] It should be noted that Figure 2 only schematically shows some components of the electronic device 1000, and the actual shape and size of these components are not limited by Figure 2 and the following figures.

[0107] It should be noted that, as shown in Figure 2, the first end 130 of the electronic device 1000 represents the bottom of the electronic device 1000, and the second end 140 represents the top of the electronic device 1000. It is understood that, in some other embodiments, the first end 130 of the electronic device 1000 can be the top of the electronic device, and the second end 140 can be the bottom of the electronic device 1000. In other words, in some other embodiments, the mounting positions of the speaker module 40 and the second speaker 80 can be interchanged, and the mounting positions of the first microphone 60 and the second microphone 90 can be interchanged.

[0108] Please refer to Figures 2 to 4A. Figure 3 is a structural schematic diagram of the middle frame 30 in some embodiments of the electronic device 1000 shown in Figure 2; Figure 4A is a structural schematic diagram of part of the middle frame 30 shown in Figure 3 from another perspective.

[0109] In some embodiments, the middle frame 30 may be provided with a first mounting groove 301, the opening of which may face the second cover plate 20. The first mounting groove 301 is located at the first end 130.

[0110] For example, the middle frame 30 may be provided with a first connecting hole 302, which penetrates the bottom wall of the first mounting groove 301.

[0111] For example, the bottom wall of the first mounting groove 301 is provided with a plurality of mounting posts 303, which are spaced apart.

[0112] For example, the middle frame 30 may be provided with a first sound outlet channel 304, the first sound outlet channel 304 forms a first opening 3041 in the inner wall of the first mounting groove 301, and the first sound outlet channel 304 forms a plurality of first sound outlets 3042 on the end face of the middle frame 30.

[0113] The multiple first sound outlets 3042 have the same shape so that the appearance of the multiple first sound outlets 3042 is consistent, which helps to improve the appearance of the electronic device 1000.

[0114] The multiple first sound outlets 3042 can be arranged at equal intervals. Specifically, the multiple first sound outlets 3042 can be arranged at equal intervals along the second direction Y to improve the appearance of the first sound outlets 3042, thereby improving the appearance of the electronic device 1000.

[0115] For example, the middle frame 30 may also be provided with a first pickup channel 305, the first pickup channel 305 forming a second opening 3051 in the bottom wall of the first mounting groove 301, and the first pickup channel 305 forming a first pickup port 3052 on the end face of the middle frame 30.

[0116] The shape of the first pickup port 3052 can be the same as that of the first output port 3042, so that the shape of the first output port 3042 is consistent with that of the first pickup port 3052, thereby improving the appearance of the electronic device 1000 at the first end 130.

[0117] The first pickup port 3052 can be arranged on one side of multiple first output ports 3042. Specifically, the first pickup port 3052 and multiple first output ports 3042 can be arranged in the second direction Y. The distance between the first pickup port 3052 and the first output port 3042 is equal to the distance between two adjacent first output ports 3042, so that the openings on the end face of the first end 130 and the middle frame 30 have the same shape and are arranged at equal intervals, which is beneficial to the harmonious and unified appearance.

[0118] For example, the bottom wall of the first mounting groove 301 may include a first part and a second part, the second part of the bottom wall of the first mounting groove 301 is higher than the first part, the first connecting hole 302 penetrates the first part of the bottom wall of the first mounting groove 301, and the second opening 3051 is formed in the second part of the bottom wall of the first mounting groove 301.

[0119] In some embodiments, the middle frame 30 may also be provided with a second connecting hole 306, which can penetrate the middle frame 30, and the second connecting hole 306 is spaced apart from the first mounting groove 301.

[0120] Please refer to Figures 3 to 4B. Figure 4B is a schematic diagram of the structure in some embodiments after the frame 30 shown in Figure 3 is cut open along line AA.

[0121] In some embodiments, the first sound outlet channel 304 may include a first sub-hole 3043 and a second sub-hole 3044. There are multiple first sub-holes 3043 arranged side-by-side, each communicating with a second sub-hole 3044. The first sub-holes 3043 form a first sound outlet 3042 on the end face of the middle frame 30, and the multiple first sub-holes 3043 form multiple first sound outlets 3042 on the end face of the middle frame 30. The second sub-hole 3044 forms a first opening 3041 on the inner wall of the first mounting groove 301.

[0122] In some embodiments, the first pickup channel 305 may include a third sub-hole 3053, a fourth sub-hole 3054, and a fifth sub-hole 3055. The third sub-hole 3053 forms a first pickup hole on the end face of the middle frame 30, the fifth sub-hole 3055 forms a second opening 3051 in the second portion of the bottom wall of the first mounting groove 301, and the fourth sub-hole 3054 connects the third sub-hole 3053 and the fifth sub-hole 3055.

[0123] For example, the extension direction of the third sub-hole 3053 is the same as that of the first sub-hole 3043, while the extension direction of the fourth sub-hole 3054 is different from that of the third sub-hole 3053. In this embodiment, by setting the fourth sub-hole 3054, the position of the third sub-hole 3053 is changed, so that the first pickup port 3052 formed by the third sub-hole 3053 on the end face of the middle frame 30 can be arranged at equal intervals with the multiple first sound outlets 3042. At the same time, by setting the extension direction of the third sub-hole 3053 to be consistent with the extension direction of the first sub-hole 3043, it is beneficial to achieve the consistency of the shape of the first pickup port 3052 and the first sound outlet 3042.

[0124] The first pickup port 3052 and the first output port 3042 can both be circular. It should be noted that the first pickup port 3052 and the first output port 3042 can also be other shapes, which can be designed according to actual applications and are not limited here.

[0125] Please refer to Figures 5 to 8. Figure 5 is a structural schematic diagram of the speaker module 40 in the electronic device 1000 shown in Figure 2 in some embodiments; Figure 6 is a partial structural exploded view of the speaker module 40 shown in Figure 5 in some embodiments; Figure 7 is a structural schematic diagram of the speaker module 40 shown in Figure 5 from another perspective; and Figure 8 is a partial structural exploded view of the speaker module 40 shown in Figure 7 in some embodiments.

[0126] In some embodiments, the speaker module 40 may include a sound cavity shell 401, a first speaker 402, and a second waterproof and breathable valve 403. The first speaker 402 is installed inside the sound cavity shell 401. The sound cavity shell 401 includes a first wall 4011, a second wall 4012, and a third wall 4013. The first wall 4011 may have a first through hole 4014. The second wall 4012 and the third wall 4013 are disposed opposite each other, with the first wall 4011 connecting the second wall 4012 and the third wall 4013. The second waterproof and breathable valve 403 is disposed on the first wall 4011, covering the first through hole 4014.

[0127] For example, the acoustic cavity housing 401 includes a first housing 401a and a second housing 401b. The first housing 401a forms a second wall 4012, and the second housing 401b includes an adjacent first wall 4011 and a third wall 4013. The first housing 401a and the second housing 401b are connected to form a space for accommodating the first speaker 402.

[0128] The third wall 4013 may be provided with a second through hole 4015, which connects to the space in the acoustic cavity shell 401 where the first speaker 402 is installed.

[0129] The third wall 4013 may be provided with a limiting rib 4016 inside, which can provide installation limit for the first speaker 402.

[0130] The first sound-emitting surface 4021 of the first speaker 402 faces the third wall 4013, so that the first speaker 402 can emit sound in the direction of the third wall 4013.

[0131] The second shell 401b has mounting holes 4011b at both ends.

[0132] For example, the second waterproof and breathable valve 403 can cover the first through hole 4014 to prevent water vapor and impurities from entering the first through hole 4014 while ensuring that air can pass through the first through hole 4014.

[0133] The second waterproof and breathable valve 403 may include a second foam 4031 and a second waterproof and breathable membrane 4032. The second foam 4031 is connected to the periphery of the second waterproof and breathable membrane 4032, and the second waterproof and breathable membrane 4032 covers the first through hole 4014.

[0134] Please refer to Figures 5, 7, 9A and 9B. Figure 9A is a structural schematic diagram of the speaker module 40 shown in Figure 5 after being cut along line BB in some embodiments; Figure 9B is a structural schematic diagram of the speaker module 40 shown in Figure 7 after being cut along line CC in some embodiments.

[0135] In some embodiments, the first loudspeaker 402 may form a first front cavity 4017 with the inner wall of the acoustic cavity shell 401, so that after the first loudspeaker 402 emits sound through the first sound-emitting surface 4021, the sound can be emitted towards the outside of the acoustic cavity shell 401 through the first front cavity 4017. Specifically, the first sound-emitting surface 4021 of the first loudspeaker 402 is spaced apart from the third wall 4013 to form the first front cavity 4017.

[0136] In this embodiment, since the third wall 4013 is provided with a limiting rib 4016, the first speaker 402 can be installed on the limiting rib 4016. At the same time, the limiting rib 4016 is arranged around the first sound outlet surface 4021 to separate the first front cavity 4017 formed between the first sound outlet surface 4021 and the third wall 4013 from the space next to the limiting rib 4016, which is beneficial to the sound output effect of the first speaker 402.

[0137] In this embodiment, due to the provision of the first through hole 4014, the first front cavity 4017 can be connected to the outside of the acoustic cavity shell 401, so that the first speaker 402 can emit sound to the outside of the acoustic cavity shell 401 in sequence through the first front cavity 4017 and the first through hole 4014.

[0138] In this embodiment, due to the setting of the second waterproof and breathable valve 403, while it can prevent water vapor and impurities from entering the first front cavity 4017, it can also ensure that the first speaker 402 can emit sound through the second waterproof and breathable valve 403.

[0139] Please refer to Figures 7, 9B and 10. Figure 10 is a schematic diagram of the structure of the speaker module 40 shown in Figure 7 with the first waterproof and breathable valve 50 installed in some embodiments.

[0140] In some embodiments, the first waterproof and breathable valve 50 can be installed on the third wall 4013 and cover the second through hole 4015 to prevent water vapor and impurities at the first through hole 4014 while ensuring that air can pass through the second through hole 4015.

[0141] For example, the first waterproof and breathable valve 50 includes a first foam 501 and a first waterproof and breathable membrane 502. The first foam 501 is connected to the periphery of the first waterproof and breathable membrane 502 and installed on the third wall 4013. The first waterproof and breathable membrane 502 covers the second through hole 4015.

[0142] Please refer to Figures 11 to 13B. Figure 11 is a schematic diagram of the structure shown in Figure 10 and the first microphone 60 installed on the middle frame 30 shown in Figure 3 in some embodiments; Figure 12 is a schematic diagram of the structure shown in Figure 11 from another perspective; Figure 13A is a partial schematic diagram of the structure shown in Figure 12 after being cut along line DD in some embodiments; Figure 13B is a schematic diagram of the structure shown in Figure 13A from another perspective.

[0143] In some embodiments, the speaker module 40 and the first microphone 60 may both be installed within the first mounting slot 301. Specifically, the speaker module 40 is installed in the first portion of the bottom wall of the first mounting slot 301, and the first microphone 60 is installed in the second portion of the bottom wall of the first mounting slot 301.

[0144] For example, the mounting hole 4011b of the acoustic cavity shell 401 can be connected with the mounting post 303 of the first mounting groove 301 to fix the speaker module in the first mounting groove 301 and improve the installation stability of the speaker module 40.

[0145] For example, the first wall 4011 of the acoustic cavity shell 401 can be disposed facing the first opening 3041, the first wall 4011 abuts against the inner wall of the first mounting groove 301, and the third wall 4013 can abut against the bottom wall of the first mounting groove 301, so as to realize the installation of the speaker module in the first mounting groove 301.

[0146] For example, the first sound outlet channel 304 can connect the top side space of the first speaker 402 to the outside of the electronic device 1000. The top side space of the first speaker 402 is the space between the first sound outlet surface 4021 of the first speaker 402 and the third wall 4013, which is also the first front cavity 4017. Since the first wall 4011 faces the first opening 3041, the first through hole 4014 can connect the first front cavity 4017 and the first sound outlet channel 304.

[0147] The second waterproof and breathable valve 403 can be disposed between the inner wall of the first wall 4011 and the first mounting groove 301 to improve the installation stability of the second waterproof and breathable membrane 4032, thereby improving the sealing performance of the first through hole 4014 on the first wall 4011.

[0148] The second waterproof and breathable membrane 4032 can cover the first through hole 4014 and the first opening 3041. The second foam 4031 abuts against the first wall 4011 and the inner wall of the first mounting groove 301. The second foam 4031 is in a compressed state.

[0149] In this embodiment, the second foam 4031 allows the speaker module 40 and the middle frame 30 to be pressed together at the inner wall of the first mounting groove 301. This seals the outer periphery of the first opening 3041 and the first through hole 4014, improving airtightness. This not only prevents external moisture and impurities from entering the first opening 3041 or the first through hole 4014, but also improves the sound output of the first speaker 402. Furthermore, the second waterproof and breathable membrane 4032 not only prevents external moisture and impurities from entering the first front cavity 4017 through the first sound outlet channel 304, but also ensures unobstructed sound output between the first front cavity 4017 and the first sound outlet channel 304, further enhancing the sound output.

[0150] For example, the third wall 4013 of the acoustic cavity shell 401 can abut against the bottom wall of the first mounting groove 301. The second through hole 4015 of the third wall 4013 can be directly opposite the first connecting hole 302.

[0151] The first waterproof and breathable valve 50 can be disposed between the third wall 4013 and the bottom wall of the first mounting groove 301, that is, the third wall 4013 abuts against the bottom wall of the first mounting groove 301 through the first waterproof and breathable valve 50. The first waterproof and breathable valve 50 covers the first connecting hole 302 and the second through hole 4015.

[0152] In this embodiment, the first waterproof and breathable valve 50 is disposed between the third wall 4013 and the bottom wall of the first mounting groove 301, which is beneficial to improving the airtightness of the connection between the first connecting hole 302 and the second through hole 4015.

[0153] The first waterproof and breathable membrane 502 can cover the second through hole 4015 and the first connecting hole 302. The first foam 501 can abut against the third wall 4013 and the bottom wall of the first mounting groove 301. The first foam 501 is in a compressed state.

[0154] In this embodiment, by setting the first foam 501, the speaker module 40 and the middle frame 30 can be pressed together at the bottom wall of the first mounting groove 301, so that the first foam 501 can seal the outer periphery of the connection between the first connecting hole 302 and the second through hole 4015, thereby improving the airtightness at this point.

[0155] In some embodiments, the extension direction of the first sub-hole 3043 of the first sound outlet channel 304 may be different from the extension direction of the second sub-hole 3044. Specifically, the extension direction of the first sub-hole 3043 may be parallel to the first direction X, and the extension direction of the second sub-hole 3044 may be inclined towards the opening direction of the first mounting groove 301 relative to the extension direction of the first sub-hole 3043.

[0156] In this embodiment, by setting the extension direction of the first sub-hole 3043 to be parallel to the first direction X, it is beneficial to process the first sub-hole 3043 and to form a regular shape for the first sound outlet 3042, thereby improving the appearance of the electronic device 1000. By setting the extension direction of the second sub-hole 3044 to be different from that of the first sub-hole 3043, it is beneficial to adjust the position of the first opening 3041 on the inner wall of the first mounting groove 301 to match the position of the first through hole 4014 on the cavity shell 401, which is beneficial to adapting the first mounting groove 301 for mounting the speaker module 40. In addition, this design also helps to ensure that the first sound outlet 3042 is located in the center region of the end face of the middle frame 30 in the thickness direction, thus improving the appearance of the electronic device 1000 on the end face of the middle frame 30.

[0157] Please refer to Figures 11, 12 and 14. Figure 14 is a partial structural diagram of some embodiments of the structure shown in Figure 12 after being cut along line EE.

[0158] In some embodiments, the first microphone 60 can be mounted on the bottom wall of the first mounting groove 301 via a first sealing ring 70. In this embodiment, the first sealing ring 70 helps to improve the airtightness between the first microphone 60 and the bottom wall of the first mounting groove 301, that is, it helps to improve the airtightness between the first pickup surface and the second opening 3051, thereby improving the pickup effect of the first microphone 60.

[0159] The first pickup channel 305 can connect the top side space of the first microphone 60 with the external space of the electronic device 1000. The top side space of the first microphone 60 is the space formed by the first pickup surface 601, the bottom wall of the first mounting groove 301, and the first sealing ring 70.

[0160] For example, the extension direction of the fifth sub-hole 3055 may differ from the extension direction of the fourth sub-hole 3054 and also from the extension direction of the third sub-hole 3053. In this embodiment, by designing the extension directions of the third sub-hole 3053, the fourth sub-hole 3054, and the fifth sub-hole 3055, the installation position of the first microphone 60 and the position of the first pickup port 3052 can be considered. This reduces the extra space occupied by the first microphone 60 and ensures that the design of the first pickup port 3052 is consistent with the design of the first sound outlet 3042, thereby improving the appearance of the electronic device 1000.

[0161] Please refer to Figures 1A, 15A and 15B. Figure 15A is a partial structural diagram of the electronic device 1000 shown in Figure 1A after being cut along line FF in some embodiments; Figure 15B is a structural diagram of the structure shown in Figure 15A from another perspective.

[0162] In some embodiments, the first connecting hole 302 can connect the inner cavity of the electronic device 1000 with the first sound output channel 304. A first waterproof and breathable valve 50 is disposed at and covers the first connecting hole 302.

[0163] In this embodiment, the design of the first connecting hole 302 enables communication between the inner cavity of the electronic device 1000 and the outside of the electronic device 1000, thereby achieving pressure balance between the inside and outside of the electronic device 1000 and thus achieving pressure relief. The first waterproof and breathable valve 50, located at the first connecting hole 302, ensures the interaction of air flow between the inside and outside of the electronic device 1000 while preventing external moisture and impurities from entering the interior of the electronic device 1000, thus providing dust and moisture protection. The first waterproof and breathable valve 50 can also be called a balance valve. Since the inner cavity of the electronic device 1000 can be depressurized through the first connecting hole 302 and the first sound outlet channel 304, the electronic device 1000 can achieve pressure balance by using the first sound outlet 3042, eliminating the need for a separate balance port. This shortens the channel length required for internal pressure relief and reduces the design of the balance port, allowing for a concealed design that improves the appearance and refinement of the electronic device 1000.

[0164] For example, the first cover plate 10 can be enclosed with the middle frame 30 to form a first space 150, and the second cover plate 20 can be enclosed with the middle frame 30 to form a second space 160. The second connecting hole 306 can connect the first space 150 and the second space 160. The first connecting hole 302 can connect the first space 150 and the first sound outlet channel 304, or the first connecting hole 302 can connect the second space 160 and the first sound outlet channel 304. Wherein, the first space 150 and the second space 160 are both internal cavities of the electronic device 1000.

[0165] In this embodiment, the space on both sides of the middle frame 30 can be connected by the second connecting hole 306, so that the space on both sides of the middle frame 30 can be depressurized by the first sound outlet channel 304, thereby achieving air pressure balance, which is beneficial to the internal air pressure stability of the electronic device 1000.

[0166] In some other embodiments, the electronic device 1000 may also include only one side space, where the first cover plate 10 and the middle frame 30 can enclose to form a first space 150, and there is no gap between the second cover plate 20 and the middle frame 30, and the first connecting hole 302 can connect the first space 150 and the first sound outlet channel 304; or, there is no gap between the first cover plate 10 and the middle frame 30, and the second cover plate 20 and the middle frame 30 can enclose to form a second space 160, and the first connecting hole 302 can connect the second space 160 and the first sound outlet channel 304.

[0167] In some embodiments, the first connecting hole 302 can connect the first space 150 and the first front cavity 4017, so that the inner cavity of the electronic device 1000 can be depressurized through the first connecting hole 302, the second through hole 4015, the first front cavity 4017, the first through hole 4041, and the first sound outlet channel 304.

[0168] In this embodiment, since the first waterproof and breathable valve 50 is disposed between the third wall 4013 of the acoustic cavity shell 401 and the bottom wall of the first mounting groove 301, it is beneficial to improve the installation stability of the first waterproof and breathable valve 50, thereby improving the airtightness between the first connecting hole 302 and the second through hole 4015. This not only allows for pressure relief of the internal cavity of the electronic device 1000, but also helps to prevent external moisture, impurities, etc. from entering the internal cavity of the electronic device 1000.

[0169] Please refer to Figure 16, which is a partial structural schematic diagram of the electronic device 1000 shown in Figure 1A cut along line FF in some other embodiments. It should be noted that the electronic device 1000 shown in Figure 16 may include some features of the embodiment shown in Figure 15A, and the same features will not be described again here.

[0170] In some embodiments, the first connecting hole 302 can penetrate through the side wall of the first sound outlet channel 304 and connect to the first sound outlet channel 304. The first waterproof and breathable valve 50 is disposed at the end of the first connecting hole 302 away from the first sound outlet channel 304 and covers the first connecting hole 302.

[0171] In this embodiment, the first connecting hole 302 can be directly connected to the first sound output channel 304, so that the inner cavity of the electronic device 1000 can be depressurized through the first connecting hole 302 and the first sound output channel 304 in sequence. The depressurization path is short, which is beneficial to ensuring the airtightness of the depressurization path.

[0172] For example, the first connecting hole 302 can penetrate the inner wall of the second sub-hole 3044 of the first sound outlet channel 304 and communicate with the second sub-hole 3044.

[0173] In this embodiment, since the second sub-hole 3044 is farther from the end face of the middle frame 30 compared to the first sub-hole 3043, and the first connecting hole 302 penetrates the inner wall of the second sub-hole 3044, it can prevent the first connecting hole 302 from being too close to the end face of the middle frame 30, thus avoiding the middle frame 30 from having an excessively thin wall thickness at the first connecting hole 302, thereby ensuring the structural strength of the middle frame 30 in the area where the first connecting hole 302 is located. Furthermore, since the extension direction of the second sub-hole 3044 is different from that of the first sub-hole 3043, and the first connecting hole 302 penetrates the inner wall of the second sub-hole 3044, it can prevent the first connecting hole 302 from being directly visible from the first sound outlet 3042, which is beneficial to improving the appearance of the electronic device 1000.

[0174] In some examples, the first connecting hole 302 can connect the first space 150 and the second sub-hole 3044, while in other examples, the first connecting hole 302 can connect the second space 160 and the second sub-hole 3044.

[0175] It should be noted that when the structural strength of the middle frame 30 is sufficient, the first connecting hole 302 can also be designed to connect the first sub-hole 3043. The specific design can be adapted to the actual product of the electronic device 1000. Understandably, as long as the first connecting hole 302 can connect the inner cavity of the electronic device 1000 to the outside of the electronic device 1000, the first connecting hole 302 can connect to any position on the path between the first sound outlet surface 4021 and the first sound outlet 3042. The specific connection points are illustrated in the embodiment but are not limited thereto.

[0176] Please refer to Figures 14 and 17. Figure 17 is a partial structural diagram of some embodiments after being cut open along line GG of Figure 1A.

[0177] In this embodiment, the structure of the first pickup channel 305 is decoupled from the structures of the first cover plate 10 and the second cover plate 20. As long as the first pickup channel 305 can connect the top side space of the first microphone 60 with the outside of the electronic device 1000, and the first pickup port 3052 can form an appearance design and arrangement pattern consistent with the first sound outlet 3042, it is acceptable.

[0178] Please refer to Figures 18 and 19. Figure 18 is a structural schematic diagram of the middle frame 30 in the electronic device 1000 shown in Figure 2 in some other embodiments; Figure 19 is a structural schematic diagram of the middle frame 30 shown in Figure 18 from another perspective.

[0179] In some embodiments, the middle frame 30 may also be provided with a second mounting groove 307, a first slot 308, and a fourth connecting hole 309. The second mounting groove 307, the first slot 308, and the fourth connecting hole 309 are located at the second end 140 of the electronic device 1000. The opening orientation of the first slot 308 is opposite to the opening orientation of the second mounting groove 307, and the fourth connecting hole 309 penetrates the bottom wall of the first slot 308 and the bottom wall of the second mounting groove 307, and connects the first slot 308 and the second mounting groove 307.

[0180] In some embodiments, the middle frame 30 may also be provided with a second slot 310 and a fifth connecting hole 311. The opening orientation of the second slot 310 is the same as that of the first slot 308. The second slot 310 is located at the second end 140 and is spaced apart from the first slot 308. The fifth connecting hole 311 can penetrate through the bottom wall of the second slot 310.

[0181] For example, one end of the first slot 308 can be connected to the fourth connecting hole 309, and the other end of the first slot 308 extends toward the second slot 310.

[0182] For example, the second slot 310 may include a first sub-slot 3101 and a second sub-slot 3102. The size of the first sub-slot 3101 is larger than the size of the second sub-slot 3102, and the second sub-slot 3102 is recessed into the bottom wall of the first slot. A portion of the fifth connecting hole 311 penetrates the bottom wall of the first sub-slot 3101, and another portion penetrates the bottom wall of the second sub-slot 3102.

[0183] Please refer to Figures 20 and 21. Figure 20 is a structural schematic diagram of the middle frame 30 shown in Figure 18 in some embodiments, in which the second speaker 80 and the second microphone 90 shown in Figure 2 are installed. Figure 21 is a structural schematic diagram of the structure shown in Figure 20 from another perspective.

[0184] In some embodiments, the second speaker 80 and the second microphone 90 are both located at the second end 140 of the electronic device 1000 and are both mounted on the middle frame 30, with the second speaker 80 and the second microphone 90 spaced apart.

[0185] For example, the second speaker 80 can be installed in the second mounting groove 307, with the second sound-emitting surface 801 of the second speaker 80 facing the bottom wall of the second mounting groove 307 and covering the fourth connecting hole 309.

[0186] For example, the second microphone 90 is located on the other side of the middle frame 30 opposite to the second slot 310, and the second pickup surface 901 of the second microphone 90 faces the fifth connecting hole 311 and covers the fifth connecting hole 311.

[0187] The second microphone 90 can be installed on the middle frame 30 through the second sealing ring 100 to improve the sealing between the second pickup surface 901 and the fifth through hole, which is beneficial to improving the pickup effect of the second microphone 90.

[0188] In some embodiments, the seal 120 may be disposed on the middle frame 30, and the seal 120 may be disposed along the periphery of the first slot 308 and cover a portion of the second slot 310.

[0189] Please refer to Figures 22A and 22B. Figure 22A is a schematic diagram of the structure shown in Figure 21 after being cut along line HH in some embodiments; Figure 22B is a schematic diagram of the structure shown in Figure 21 after being cut along line II in some embodiments.

[0190] In some embodiments, the second sound-emitting surface 801 of the second speaker 80 may be spaced apart from the bottom wall of the second mounting groove 307 to form a top side space of the second speaker 80, so as to provide ample space for the second sound-emitting surface 801.

[0191] In some embodiments, a top space for forming the second microphone 90 can be formed between the second pickup surface 901, the middle frame 30, and the second sealing ring 100 of the second microphone 90.

[0192] For example, the fifth connecting hole 311 may include a sixth sub-hole 3111 and a seventh sub-hole 3112. The sixth sub-hole 3111 penetrates the bottom wall of the second slot 310, and the seventh sub-hole 3112 connects the sixth sub-hole 3111 with the top side space of the second microphone 90.

[0193] The inner diameter of the sixth sub-hole 3111 can be larger than that of the seventh sub-hole 3112, which is beneficial to improving the sound pickup effect of the second microphone 90.

[0194] For example, the shielding member 110 may be disposed in the first sub-slot 3101 of the second slot 310, and the shielding member 110 may shield a portion of the second sub-slot 3102.

[0195] Please refer to Figures 23 to 24B. Figure 23 is a partially enlarged schematic diagram of the electronic device 1000 shown in Figure 1A at the second end 140 in some embodiments; Figure 24A is a partial structural schematic diagram of the electronic device 1000 shown in Figure 23 after being cut along line JJ in some embodiments; Figure 24B is a partial structural schematic diagram of the electronic device 1000 shown in Figure 23 after being cut along line KK in some embodiments.

[0196] In some embodiments, the middle frame 30 and the first cover plate 10 may be arranged at the second end 140 to form a slit 170. The electronic device 1000 may be provided with a second sound output channel 180 and a second sound pickup channel 190, the second sound output channel 180 connecting the slit 170 and the top space of the second speaker 80, and the second sound pickup channel 190 connecting the slit 170 and the top space of the second microphone 90.

[0197] In this embodiment, the design of the slit 170 allows the second speaker 80 to share the slit 170 for sound output and the second microphone 90 to pick up sound, reducing the structural design of sound output and sound pickup. This helps to ensure the integrity of the appearance of the electronic device 1000 and also improves the consistency of the appearance of the electronic device 1000, making the appearance of the electronic device 1000 more beautiful and improving the sophistication of the electronic device 1000.

[0198] In some examples, the middle frame 30 has a first notch at the second end 140, and the first cover plate 10 and the middle frame 30 enclose the first notch at the second end 140 to form a slit 170.

[0199] In other examples, the first cover plate 10 has a second notch at the second end 140, and the first cover plate 10 and the middle frame 30 enclose the second notch at the second end 140 to form a slit 170.

[0200] In some other examples, the middle frame 30 is provided with a third notch at the second end 140, and the first cover plate 10 is provided with a fourth notch at the second end 140. The first cover plate 10 and the middle frame 30 enclose each other at the second end 140 so that the third notch and the fourth notch communicate to form an opening 170.

[0201] In some other embodiments, the middle frame 30 may also form a slit 170 with the second cover plate 20 at the second end 140.

[0202] In some embodiments, the electronic device 1000 may form a second sound outlet channel 180 on one side of the second sound outlet surface 801 of the second speaker 80. Specifically, the first cover plate 10, the middle frame 30, and the sealing member 120 form the second sound outlet channel 180. The second sound outlet channel 180 includes a channel formed by the first cover plate 10, the middle frame 30, and the sealing member 120 at the first slot 308, and a fourth connecting hole 309, so that the second sound outlet channel 180 can connect the top side space of the second speaker 80 and the opening 170 to realize the sound output of the second speaker 80.

[0203] In this embodiment, the sealing of the middle frame 30 and the first cover plate 10 is improved due to the setting of the sealing element 120, thereby improving the airtightness of the second sound outlet channel 180, which is beneficial to improving the sound output effect of the second speaker 80.

[0204] In some embodiments, the electronic device 1000 may form a second pickup channel 190 on one side of the second pickup surface 901 of the second microphone 90. Specifically, the first cover plate 10, the middle frame 30, the shielding member 110, and the sealing member 120 are arranged to form the second pickup channel 190. The second pickup channel 190 includes the first cover plate 10, the middle frame 30, the shielding member 110, and the sealing member 120 forming a channel at the second slot 310 and a fifth connecting hole 311, so that the second pickup channel 190 can connect the top side space of the second microphone 90 and the opening 170 to realize the pickup of the second microphone 90.

[0205] In this embodiment, the sealing of the middle frame 30 and the first cover plate 10 is improved due to the setting of the sealing element 120, thereby improving the airtightness of the second pickup channel 190 and improving the pickup effect of the second microphone 90.

[0206] In this embodiment, since the first slot 308 and the second slot 310 are spaced apart, the interference between the sound output of the second speaker 80 and the sound pickup of the second microphone 90 can be reduced.

[0207] In this embodiment, the shielding member 110 can block and guide the sound pickup of the second microphone 90, preventing the opening of the second connecting hole 306 at the second slot 310 from being too large, which is beneficial to improving the sound pickup effect of the second microphone 90.

[0208] It should be noted that the design of the first sound outlet and the first microphone outlet at the first end of the electronic device can be interchanged with the design of the second sound outlet and the second microphone outlet at the second end of the electronic device. Specifically, the electronic device can have a slit at the first end so that the sound output of the first speaker and the sound pickup of the first microphone share the same slit, and the electronic device can have multiple round holes at the second end so that the sound outlet of the second speaker and the sound pickup of the second microphone have the same appearance.

[0209] It should be noted that the design of the first connecting hole and the first waterproof and breathable valve at the first end of the electronic device can also be applied to the second end. Specifically, the first connecting hole can connect the internal cavity of the electronic device and the second sound outlet channel, and the first waterproof and breathable valve can be set at the connection between the first connecting hole and the second sound outlet channel, so that the second sound outlet channel can be used to relieve pressure inside the electronic device, and the setting of the balance hole can be reduced.

[0210] It should be noted that, in the absence of conflict, the embodiments and 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.

[0212] The above are merely some embodiments and implementation methods of this application. 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.
