Description

Technical Field

[0001] This application relates to the field of electronic equipment technology, and more particularly to a sound-generating device and an electronic device. Background Technology

[0002] For electronic devices with sound-emitting devices, larger electronic device housings typically have greater weight and higher natural frequencies. To avoid resonance between the sound-emitting device and the housing, which could affect the user experience, larger electronic devices need to be matched with larger sound-emitting devices. This is because larger sound-emitting devices provide a larger air volume, lowering their resonant frequency so that it differs from the natural frequency of the housing, thus reducing the risk of resonance.

[0003] However, adapting different sized housings to different sized sound-generating devices is detrimental to the manufacturing and development costs of electronic devices, so the above problems urgently need to be solved. Utility Model Content

[0043] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of the specification.

[0044] like Figures 1 to 7 As shown, the first aspect of this application provides a sound-generating device 2, which may include a sound-generating unit 21, a first target member 23 and a second target member 25, as well as a first cavity 22 extending along a first direction A and a second cavity 24 extending along a second direction B; the first target member 23 and the first cavity 22 can be connected to form a first sound cavity 26 and can have different switchable first relative positional relationships along the first direction A, and the volume of the first sound cavity 26 is different under different first relative positional relationships; the second target member 25 and the second cavity 24 can be connected to form a second sound cavity 27 and can have different switchable second relative positional relationships along the second direction B, and the volume of the second sound cavity 27 is different under different second relative positional relationships; wherein, the first sound cavity 26 is connected to the second sound cavity 27, the sound-generating unit 21 is disposed in the first sound cavity 26 or the second sound cavity 27, and the first direction A and the second direction B intersect.

[0045] This application provides a sound-generating device 2, which may include a sound-generating unit 21 to meet the user's auditory needs for electronic devices. The sound-generating unit 21 can convert electrical signals into sound wave signals and may be in the form of a moving coil loudspeaker, a balanced armature loudspeaker, a piezoelectric loudspeaker, a planar diaphragm loudspeaker, etc., with no specific limitation.

[0046] To adjust the resonant frequency of the sound-emitting unit 21 and avoid it coinciding with the inherent frequency of the electronic device housing, thus preventing resonance risks from affecting the user experience, this application can provide a first target component 23 and a first cavity 22 extending along a first direction A, a second target component 25 and a second cavity 24 extending along a second direction B. The first target component 23 and the first cavity 22 can be connected to form a first acoustic cavity 26 with switchable first relative positional relationships along the first direction A. The second target component 25 and the second cavity 24 can be connected to form a second acoustic cavity 27 with switchable second relative positional relationships along the second direction B. This allows for different volumes of the first and second acoustic cavities 26 and 27 under different first and second relative positional relationships, thereby enabling adjustable acoustic cavity volume for the sound-emitting unit 21. Furthermore, by changing the first, second, or both relative positional relationships, the resonant frequency of the sound-emitting unit 21 can be made different from the inherent frequency of the electronic device housing, thus avoiding resonance risks.

[0047] In this application, the first acoustic cavity 26 and the second acoustic cavity 27 are connected, enabling coordinated volume adjustment. The resonant frequency of the sound-generating unit 21 can be flexibly adjusted as needed by adjusting the volume of one or both acoustic cavities simultaneously. This allows for adaptation to electronic devices with different housing sizes, improving product versatility and reducing manufacturing and development costs. Specifically, for electronic devices with different housing sizes, the first relative position relationship, the second relative position relationship, or both can be changed as needed. This allows the total volume of the first acoustic cavity 26 and the second acoustic cavity 27 to be altered to adjust the resonant frequency of the sound-generating unit 21, making its housing's inherent frequency different. This eliminates the need to adapt different sized sound-generating devices 2 to different sized housings. The sound-generating device 2 provided in this application achieves universal and flexible adjustment, reducing manufacturing and development costs.

[0048] This application can connect the side of the first cavity 22 away from the first target member 23 to the side of the second cavity 24 away from the second target member 25, so that the first sound cavity 26 can be connected to the second sound cavity 27. This can make full use of the frame area inside the electronic device housing, making it easier to embed the sound-generating device 2 into the corner or edge area of ​​the device and improve space utilization.

[0049] The sound-emitting unit 21 of this application can be disposed on the side of the first acoustic cavity 26 near the second acoustic cavity 27 or on the side of the second acoustic cavity 27 near the first acoustic cavity 26. That is, by being disposed in the intersection area of ​​the first acoustic cavity 26 and the second acoustic cavity 27, the sound waves generated by the sound-emitting unit 21 can propagate through the first acoustic cavity 26 and the second acoustic cavity 27 respectively without needing an additional transition space, reducing energy loss. Simultaneously, it can form bidirectional radiation in the first direction A and the second direction B, improving sound energy output efficiency. Furthermore, disposing the sound-emitting unit 21 in the intersection area of ​​the first acoustic cavity 26 and the second acoustic cavity 27 can avoid pressure accumulation in one side of the acoustic cavity and prevent nonlinear distortion.

[0050] This application allows the sound-generating device 2 to have a dual-cavity intersecting layout by intersecting the first direction A and the second direction B. The interconnected arrangement of the first cavity 26 and the second cavity 27 enables coordinated volume adjustment, improving the efficiency of adjusting the resonant frequency of the sound-generating unit 21. Simultaneously, the dual-cavity intersecting layout of the sound-generating device 2 facilitates its placement within electronic devices, providing better spatial adaptability. In one embodiment, the first cavity 22 can be arranged along the length of the electronic device housing, and the second cavity 24 can be arranged along the width of the electronic device housing, fully utilizing the corner areas within the housing and improving space utilization. Alternatively, by setting both the first direction A and the second direction B perpendicular to the thickness direction of the housing, the sound-generating device 2 can avoid occupying excessive space in the thickness direction, thus meeting the requirements for a thinner and lighter electronic device.

[0051] This application provides a sound-generating device 2, which may include a sound-generating unit 21, a first target member 23 and a second target member 25, and a first cavity 22 extending along a first direction A and a second cavity 24 extending along a second direction B; the first target member 23 and the first cavity 22 can be connected to form a first acoustic cavity 26 and can have different switchable first relative positional relationships along the first direction A, with different volumes of the first acoustic cavity 26 under different first relative positional relationships; the second target member 25 and the second cavity 24 can be connected to form a second acoustic cavity 27 and can have different switchable second relative positional relationships along the second direction B, with different volumes of the second acoustic cavity 27 under different second relative positional relationships; wherein, the side of the first cavity 22 away from the first target member 23 can be connected to the side of the second cavity 24 away from the second target member 25, so that the first acoustic cavity 26 can be connected to the second acoustic cavity 27, and the sound-generating unit 21 can be disposed on the side of the first acoustic cavity 26 near the second acoustic cavity 27 or the side of the second acoustic cavity 27 near the first cavity 26, and the first direction A and the second direction B intersect. This application allows for adjustable volumes of the first acoustic cavity 26 and the second acoustic cavity 27 by setting the first target component 23 and the first cavity 22 to have different first relative positions, and the second target component 25 and the second cavity 24 to have different second relative positions. This, in turn, makes the total acoustic cavity volume accommodating the sound-emitting unit 21 adjustable, thus ensuring that the resonant frequency of the sound-emitting unit 21 differs from the inherent frequency of the electronic device housing, avoiding resonance risks. Furthermore, this application allows for a dual-cavity intersecting arrangement of the sound-emitting device 2 by intersecting the first direction A and the second direction B. The first acoustic cavity 26 and the second acoustic cavity 27 are connected, enabling coordinated volume adjustment. The resonant frequency of the sound-emitting unit 21 can be flexibly adjusted as needed by adjusting the volume of one cavity or both cavities simultaneously, adapting to electronic devices with different housing sizes, improving product versatility, and reducing manufacturing and development costs. Meanwhile, the sound-emitting unit 21 of this application can be disposed on the side of the first sound cavity 26 near the second sound cavity 27 or on the side of the second sound cavity 27 near the first sound cavity 26. That is, by being disposed in the intersection area of ​​the sound cavities, the emitted sound energy can form bidirectional radiation, shorten the sound wave propagation path, reduce output loss, and improve sound energy output efficiency. Through the application of this application, the technical problem of adapting sound-emitting devices 2 of different sizes to housings of different sizes is solved, which is detrimental to the manufacturing and development costs of electronic devices.

[0052] like Figure 6 and Figure 7 As shown, in some embodiments, the first direction A may be perpendicular to the second direction B.

[0053] This application allows the first direction A to be perpendicular to the second direction B, enabling the sound-generating device 2 to have a vertically intersecting dual-cavity layout in space. This layout can be L-shaped, T-shaped, or similar, making full use of the frame area inside the electronic device housing. This facilitates embedding the sound-generating device 2 into the corner or edge area of ​​the device, thereby improving space utilization.

[0054] Meanwhile, in the process of changing the first relative position relationship between the first target component 23 and the first cavity 22, or changing the second relative position relationship between the second target component 25 and the second cavity 24, or changing both the first and second relative position relationships, the first direction A can be set perpendicular to the second direction B so that the first target component 23 and the second target component 25 can not interfere with each other in space, which facilitates adjustment and prevents interference.

[0055] like Figures 2 to 5 As shown, in some embodiments, the first cavity 22 may have a first target segment 221, the first target component 23 may have a second target segment 231, the second target segment 231 may be adapted to and connected to the first target segment 221, and the projected area of ​​the second target segment 231 toward the first target segment 221 is different under different first relative positional relationships; the second cavity 24 may have a third target segment 241, the second target component 25 may have a fourth target segment 251, the fourth target segment 251 may be adapted to and connected to the third target segment 241, and the projected area of ​​the fourth target segment 251 toward the third target segment 241 is different under different second relative positional relationships.

[0056] This application achieves a first acoustic cavity 26 by adapting the second target segment 231 of the first target component 23 to the first target segment 221 of the first cavity 22. When the volume of the first acoustic cavity 26 in the sound-emitting device 2 needs to be changed for different sizes of electronic device housings, the projected area of ​​the second target segment 231 towards the first target segment 221 can be altered. This allows for different first relative positional relationships between the first target component 23 and the first cavity 22. Specifically, the larger the projected area of ​​the second target segment 231 towards the first target segment 221, the larger the overlap area between the second target segment 231 and the first target segment 221, and the smaller the volume of the first acoustic cavity 26. Conversely, the smaller the projected area of ​​the second target segment 231 towards the first target segment 221, the smaller the overlap area between the second target segment 231 and the first target segment 221, and the larger the volume of the first acoustic cavity 26.

[0057] Similarly, this application can achieve a second acoustic cavity 27 by adapting and connecting the fourth target segment 251 of the second target component 25 with the third target segment 241 of the second cavity 24. When the volume of the second acoustic cavity 27 in the sound-emitting device 2 needs to be changed for different sizes of electronic device housings, the projected area of ​​the fourth target segment 251 toward the third target segment 241 can be changed to allow the second target component 25 and the second cavity 24 to have different second relative positional relationships. That is, the larger the projected area of ​​the fourth target segment 251 toward the third target segment 241, the larger the overlapping area of ​​the fourth target segment 251 and the third target segment 241, and the smaller the volume of the second acoustic cavity 27. Conversely, the smaller the projected area of ​​the fourth target segment 251 toward the third target segment 241, the smaller the overlapping area of ​​the fourth target segment 251 and the third target segment 241, and the larger the volume of the second acoustic cavity 27.

[0058] like Figures 2 to 5 As shown, in some embodiments, the first target segment 221 may be provided with a plurality of first protrusions 2211 at intervals along the first direction A; the second target segment 231 may be provided with a plurality of first grooves 2311 at intervals along the first direction A, and the first protrusions 2211 and the first grooves 2311 may be adapted to each other. Under different first relative positional relationships, the number of first grooves 2311 and first protrusions 2211 adapted to each other is different; the third target segment 241 may be provided with a plurality of second protrusions 2411 at intervals along the second direction B; the fourth target segment 251 may be provided with a plurality of second grooves 2511 at intervals along the second direction B, and the second protrusions 2411 and second grooves 2511 may be adapted to each other. Under different second relative positional relationships, the number of second grooves 2511 and second protrusions 2411 adapted to each other is different.

[0059] To achieve the adaptive connection between the first target segment 221 and the second target segment 231, this application can provide multiple first protrusions 2211 at intervals along the first direction A in the first target segment 221, and multiple first grooves 2311 at intervals along the first direction A in the second target segment 231. The first cavity 22 and the first target member 23 can be connected to form the first sound cavity 26 through the adaptive connection between the first protrusions 2211 and the first grooves 2311. When the number of first grooves 2311 and first protrusions 2211 that are adapted to each other is different, that is, when the second target segment 231 of the first target member 23 and the first target segment 221 of the first cavity 22 are relatively displaced along the first direction A, the first relative positional relationship changes, which in turn causes the volume of the first sound cavity 26 to change. This allows the user to adjust the volume of the first sound cavity 26 according to their needs, so as to adjust the total sound cavity volume of the sound-emitting unit 21 in conjunction with the second sound cavity 27 connected to it, so that the resonant frequency of the sound-emitting unit 21 is different from the inherent frequency of the electronic device housing.

[0060] To achieve the adaptive connection between the third target segment 241 and the fourth target segment 251, this application can provide multiple second protrusions 2411 spaced apart along the second direction B in the third target segment 241, and multiple second grooves 2511 spaced apart along the second direction B in the fourth target segment 251. The adaptive connection between the second protrusions 2411 and the second grooves 2511 can connect the second cavity 24 and the second target member 25 to form the second sound cavity 27. When the number of second grooves 2511 and second protrusions 2411 that are adapted to each other is different, that is, when the fourth target segment 251 of the second target member 25 and the third target segment 241 of the second cavity 24 are relatively displaced along the first direction A, the second relative positional relationship changes, which in turn causes the volume of the second sound cavity 27 to change. This allows the user to adjust the volume of the second sound cavity 27 according to their needs, so as to adjust the total sound cavity volume of the sound-emitting unit 21 in accordance with the first sound cavity 26 connected to it, so that the resonant frequency of the sound-emitting unit 21 is different from the inherent frequency of the electronic device housing.

[0061] In some embodiments, the first protrusion 2211 may be disposed around the outer wall of the first target segment 221; the second protrusion 2411 may be disposed around the outer wall of the third target segment 241; the first groove 2311 may be disposed around the inner wall of the second target segment 231; and the second groove 2511 may be disposed around the inner wall of the fourth target segment 251.

[0062] This application, by having a first protrusion 2211 surrounding the outer wall of the first target segment 221 and a first groove 2311 surrounding the inner wall of the second target segment 231, allows the groove wall of the first groove 2311 to wrap around the outer edge of the surrounding first protrusion 2211 when the first protrusion 2211 and the first groove 2311 are adapted to be connected, so that the groove wall of the first groove 2311 can be fully in contact with the first protrusion 2211, thereby improving the tightness of the connection and improving the stability and reliability of the connection between the first target component 23 and the first cavity 22 to form the first sound cavity 26. To achieve the assembly of the first protrusion 2211 and the first groove 2311, the first target part 23 can be configured as a detachable split, which may include a first split and a second split. During installation, the first groove 2311 on the first split is first engaged with a portion of the outer edge of the first protrusion 2211 surrounding the first target segment 221, and then the first groove 2311 on the second split is engaged with another portion of the outer edge of the first protrusion 2211 surrounding the first target segment 221. The first split and the second split can have the same relative position with respect to the first target segment 221 in the first direction A. The first split and the second split can be fastened together to complete the installation of the first target part 23 relative to the first cavity 22.

[0063] This application, by having a second protrusion 2411 surrounding the outer wall of the third target segment 241 and a second groove 2511 surrounding the inner wall of the fourth target segment 251, allows the groove wall of the second groove 2511 to wrap around the outer edge of the surrounding second protrusion 2411 when the second protrusion 2411 and the second groove 2511 are adapted to be connected, so that the groove wall of the second groove 2511 can be fully in contact with the second protrusion 2411, thereby improving the tightness of the connection and improving the stability and reliability of the connection between the second target component 25 and the second cavity 24 to form the second sound cavity 27. To achieve the assembly of the second protrusion 2411 and the second groove 2511, the second target part 25 can be configured as a detachable split part, which may include a third split part and a fourth split part. During installation, the second groove 2511 on the third split part is first engaged with a portion of the outer edge of the second protrusion 2411 surrounding the second target segment 231, and then the second groove 2511 on the fourth split part is engaged with another portion of the outer edge of the second protrusion 2411 surrounding the second target segment 231. The third split part and the fourth split part have the same relative position with respect to the second target segment 231 in the second direction B. The third split part and the fourth split part are then fastened together to complete the installation of the second target part 25 relative to the second cavity 24.

[0064] like Figure 8 and Figure 9 As shown, in some embodiments, the first protrusion 2211 may include a first protrusion 2212 and two second protrusions 2213. The two second protrusions 2213 may be disposed on both sides of the first protrusion 2212 in the first direction A. The first protrusion 2212 may at least partially protrude from the second protrusions 2213 and may be adapted to be connected to the first groove 2311. The second protrusion 2411 may include a third protrusion 2412 and two fourth protrusions 2413. The two fourth protrusions 2413 may be disposed on both sides of the third protrusion 2412 in the second direction B. The third protrusion 2412 may at least partially protrude from the fourth protrusions 2413 and may be adapted to be connected to the second groove 2511.

[0065] To achieve a stable connection between the first protrusion 2211 and the first groove 2311, this application provides that the first protrusion 2211 may include a first protrusion 2212 and two second protrusions 2213. The two second protrusions 2213 may be disposed on both sides of the first protrusion 2212 in the first direction A. The first protrusion 2212 may at least partially protrude from the second protrusions 2213 and be adapted to connect with the first groove 2311. Thus, after the first target member 23 is installed in the first target segment 221 of the first cavity 22, the first protrusion 2212 can connect with the groove wall of the first groove 2311. The second protrusion 2213 can contact the inner wall of the first target member 23 between adjacent first grooves 2311, so that when the electronic device is affected by impact or vibration, the first protrusion 2212 located in the first groove 2311 can absorb and disperse the impact load or transient load. At the same time, the second protrusions 2213 on both sides generate friction and support force with the inner wall of the first target member 23, which can share part of the lateral stress, and thus cooperate with the first protrusion 2212 to support and avoid local stress concentration, so as to stably connect the first target member 23 with the first target segment 221 of the first cavity 22.

[0066] To achieve a stable connection between the second protrusion 2411 and the second groove 2511, this application provides that the second protrusion 2411 may include a third protrusion 2412 and two fourth protrusions 2413. The two fourth protrusions 2413 may be disposed on both sides of the third protrusion 2412 in the second direction B. The third protrusion 2412 may at least partially protrude from the fourth protrusions 2413 and may be adapted to connect with the second groove 2511. Thus, after the second target member 25 is installed in the third target segment 241 of the second cavity 24, the third protrusion 2412 may connect with the groove wall of the second groove 2511. The fourth protrusion 2413 can contact the inner wall of the second target member 25 between the adjacent second grooves 2511, so that when the electronic device is affected by impact or vibration, the third protrusion 2412 located in the second groove 2511 can absorb and disperse the impact load or transient load. At the same time, the friction and support force generated between the fourth protrusions 2413 on both sides and the inner wall of the second target member 25 can share part of the lateral stress, and thus cooperate with the third protrusion 2412 to support and avoid local stress concentration, so as to stably connect the second target member 25 with the third target segment 241 of the second cavity 24.

[0067] like Figure 8 and Figure 9 As shown, in some embodiments, the second protrusion 2213 of the adjacent first protrusion 2211 and the inner wall of the second target segment 231 can form an annular first gap 2214; the fourth protrusion 2413 of the adjacent second protrusion 2411 and the inner wall of the fourth target segment 251 can form an annular second gap 2414; a sealing element 2215 can be provided in the first gap 2214 and the second gap 2414.

[0068] In this application, the first protrusion 2212 of the first protrusion 2211 protrudes relative to the second protrusion 2213 to connect with the first groove 2311, so that the second protrusion 2213 of the adjacent first protrusion 2211 and the inner wall of the second target segment 231 of the first target member 23 can form an annular first gap 2214. Similarly, the third protrusion 2412 of the second protrusion 2411 protrudes relative to the fourth protrusion 2413 to connect with the second groove 2511, so that the fourth protrusion 2413 of the adjacent second protrusion 2411 and the inner wall of the fourth target segment 251 can form an annular second gap 2414. The application allows for the installation of a sealing element 2215 within the first gap 2214 and the second gap 2414. This ensures a tight connection between the second target segment 231 of the first target component 23 and the first target segment 221 of the first cavity 22, and a tight connection between the fourth target segment 251 of the second target component 25 and the third target segment 241 of the second cavity 24. The sealing element 2215 provides an airtight seal, preventing air leakage from the first sound cavity 26 and the second sound cavity 27, stabilizing the internal pressure of the sound cavity, and avoiding sound energy loss and noise caused by air leakage. This optimizes the sound performance of the sound-generating device 2 and improves the user experience. In this application, the sealing element 2215 can be an O-ring made of rubber, silicone, polyurethane, or a foam sealing strip made of EPDM rubber, PVC, etc. The specific material is not limited, as long as it ensures a stable seal between the first sound cavity 26 and the second sound cavity 27.

[0069] like Figure 10 As shown, a second aspect of this application provides an electronic device, which may include a housing 1 and a sound-emitting device 2; the sound-emitting device 2 may be disposed within the housing 1; wherein the sound-emitting device 2 may include a sound-emitting unit 21, a first target member 23 and a second target member 25, and a first cavity 22 extending along a first direction A and a second cavity 24 extending along a second direction B; the first target member 23 and the first cavity 22 may communicate to form a first sound cavity 26 and may have different switchable first relative positional relationships along the first direction A, wherein the volume of the first sound cavity 26 is different under different first relative positional relationships; the second target member 25 and the second cavity 24 may communicate to form a second sound cavity 27 and may have different switchable second relative positional relationships along the second direction B, wherein the volume of the second sound cavity 27 is different under different second relative positional relationships; wherein the first sound cavity 26 is connected to the second sound cavity 27, the sound-emitting unit 21 is disposed in the first sound cavity 26 or the second sound cavity 27, and the first direction A and the second direction B intersect.

[0070] For the specific structure of the sound-generating device 2, please refer to Embodiment 1, which will not be repeated here.

[0071] The electronic device provided in this application can meet the user's daily auditory needs through the setting of the sound-emitting device 2. The electronic device can be a mobile phone, tablet computer, laptop computer, home appliance, etc., and is not limited to any specific type. Different types and sizes of electronic devices have different sized housings 1. This application can set the sound-emitting device 2 inside housings 1 of different sizes. By setting the first target component 23 and the first cavity 22 to have different first relative positional relationships, and the second target component 25 and the second cavity 24 to have different second relative positional relationships, the volumes of the first sound cavity 26 and the second sound cavity 27 are adjustable, thereby making the total sound cavity volume accommodating the sound-emitting unit 21 adjustable. This ensures that the resonant frequency of the sound-emitting unit 21 is different from the natural frequency of the electronic device housing 1, avoiding the risk of resonance. At the same time, the sound-emitting device 2 can be adapted to electronic devices with different sized housings 1, improving the versatility of the sound-emitting device 2 for electronic devices with different sized housings 1 and reducing manufacturing and development costs.

[0072] like Figure 10 As shown, in one embodiment, the electronic device can be a laptop computer, and the housing can be the side housing of the laptop computer with buttons and a touchpad. This application can provide two sound-emitting devices 2, which can be arranged in an L-shape symmetrically on both sides of the touchpad to make full use of the space of the housing on both sides of the touchpad in its length direction C and width direction D. At the same time, the frame area inside the housing is utilized during placement to improve space utilization.

[0073] like Figure 11 As shown, corresponding to electronic devices with housings of different sizes, this application can adjust the volume of the first sound cavity 26 and the second sound cavity 27 by setting different first relative positions between the first target component 23 and the first cavity 22, and different second relative positions between the second target component 25 and the second cavity 24 in the sound-emitting device, thereby making the total sound cavity volume accommodating the sound-emitting unit 21 adjustable. Figure 11 As shown, the larger the size of the electronic device's casing, the larger the total volume of the sound cavity can be increased by adjusting the first sound cavity 26, the second sound cavity 27, or simultaneously adjusting the first sound cavity 26 and the second sound cavity 27.

[0074] In one embodiment, one or more sound-emitting devices 2 may be disposed within the housing 1 of the electronic device of this application. In one embodiment, such as... Figure 10 and Figure 11 As shown, there can be two sound-generating devices 2, which can be symmetrically arranged within the housing 1, so that when the user uses the electronic device, the two sound-generating devices 2 can provide a binaural effect to enhance the user's auditory experience. In another embodiment, there can be four sound-generating devices 2, which are symmetrically arranged in the four corner areas within the housing 1 to further improve the multi-directional playback effect of the sound-generating devices 2 and enhance the user's auditory experience; the specific arrangement is not limited.

[0075] A second aspect of this application provides an electronic device, which may include a housing 1 and a sound-generating device 2; the sound-generating device 2 may be disposed within the housing 1; wherein the sound-generating device 2 may include a sound-generating unit 21, a first target member 23 and a second target member 25, and a first cavity 22 extending along a first direction A and a second cavity 24 extending along a second direction B; the first target member 23 and the first cavity 22 may communicate to form a first sound cavity 26 and may have switchable different first relative positional relationships along the first direction A, wherein the volume of the first sound cavity 26 is different under different first relative positional relationships; the second target member... The first cavity 25 and the second cavity 24 can communicate to form a second acoustic cavity 27, and can have different switchable second relative positional relationships along the second direction B. Under different second relative positional relationships, the volume of the second acoustic cavity 27 is different. The side of the first cavity 22 away from the first target member 23 can be connected to the side of the second cavity 24 away from the second target member 25, so that the first acoustic cavity 26 can be connected to the second acoustic cavity 27. The sound-emitting unit 21 can be disposed on the side of the first acoustic cavity 26 near the second acoustic cavity 27 or the side of the second acoustic cavity 27 near the first acoustic cavity 26. The first direction A and the second direction B intersect. This application, by setting the first target member 23 and the first cavity 22 to have different first relative positional relationships, and the second target member 25 and the second cavity 24 to have different second relative positional relationships, makes the volumes of the first acoustic cavity 26 and the second acoustic cavity 27 adjustable, thereby making the total acoustic cavity volume accommodating the sound-emitting unit 21 adjustable, and thus making the resonant frequency of the sound-emitting unit 21 different from the natural frequency of the electronic device housing 1, avoiding the risk of resonance. Furthermore, this application arranges the sound-generating device 2 in a dual-cavity intersecting layout by intersecting the first direction A and the second direction B. The first cavity 26 and the second cavity 27 are connected to achieve coordinated volume adjustment. The resonant frequency of the sound-generating unit 21 can be flexibly adjusted as needed by adjusting the volume of one cavity or both cavities simultaneously, adapting to electronic devices with different sized housings 1, improving product versatility, and reducing manufacturing and development costs. Simultaneously, the sound-generating unit 21 can be positioned on the side of the first cavity 26 near the second cavity 27, or the second cavity 27 near the first cavity 26. This placement in the cavity intersection area allows for bidirectional sound radiation, shortens the sound wave propagation path, reduces output loss, and improves sound energy output efficiency. Through the application of this application, the technical problem of adapting different sized housings 1 to sound-generating devices 2 of different sizes, which is detrimental to the manufacturing and development costs of electronic devices, is solved.

[0076] like Figure 10 As shown, in some embodiments, the first direction A can be parallel to the width direction D of the housing 1; the second direction B can be parallel to the length direction C of the housing 1; and both the first direction A and the second direction B can be perpendicular to the thickness direction of the housing 1.

[0077] This application allows the first direction A to be parallel to the width direction D of the housing 1, and the second direction B to be parallel to the length direction C of the housing 1. This enables the sound-generating device 2 to fully utilize the corner areas within the housing 1, improving space utilization. Simultaneously, the first direction A is perpendicular to the second direction B, allowing the sound-generating device 2 to have a vertically intersecting dual-cavity layout, which can be arranged in L-shape, T-shape, etc., facilitating its embedding in corners or edges. Furthermore, this application allows both the first direction A and the second direction B to be perpendicular to the thickness direction of the housing 1, ensuring that the sound-generating device 2 does not occupy excessive space in the thickness direction, thus meeting the requirements for thinner and lighter electronic devices.

[0078] In some embodiments, the first cavity 22 and the second cavity 24 may have the same positional relationship relative to the housing 1 in the thickness direction.

[0079] This application sets the first cavity 22 and the second cavity 24 to have the same positional relationship with the shell 1 in the thickness direction. This allows the first cavity 22 and the first target component 23 to be connected, and the second cavity 24 and the second target component 25 to have the same positional relationship with the shell 1 in the thickness direction. This avoids stacking or staggered arrangement of the overall structure of the sound-generating device 2 in the thickness direction, thereby reducing the space occupied in the thickness direction and helping to meet the requirements of thinner and lighter electronic device shell 1.
