Description

Technical Field

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

[0002] In today's tablet design field, with consumers increasingly demanding thin, light, portable, and high-performance tablets, how to rationally arrange various components within limited internal space has become a key challenge in the design process. Because a tablet needs to house multiple core components such as the screen, battery, and processor, space is inherently very limited. Existing speaker components often occupy too much space and frequently conflict with the layout of other components, not only affecting the tablet's thin and light design but also limiting the full performance of other components.

[0003] The thickness and sound emission method of the speaker assembly have a significant impact on its performance. In related technologies, a plastic or metal shell is typically used to surround the diaphragm on the front side of the speaker driver, the side where the diaphragm emits sound, creating a closed or semi-closed space to form the front acoustic chamber. The rear acoustic chamber is usually located on the back of the speaker driver, opposite the front acoustic chamber. However, this structural design results in a relatively thick speaker assembly. A thicker speaker not only occupies more internal space but also affects the overall appearance design of the tablet, leading to numerous shortcomings in the thickness design of speakers on the market, making it difficult to meet users' demands for thinner and lighter tablet devices. Utility Model Content

[0014] In one possible implementation, the receiving cavity is a cuboid cavity, the speaker unit is a cuboid structure, the long side of the speaker unit extends along the length direction of the electronic device, the short side of the speaker unit extends along the width direction of the electronic device, the speaker housing also includes a second outer surface opposite to the first outer surface, and both the first outer surface and the second outer surface are located within the receiving cavity along the thickness direction of the electronic device.

[0015] In one possible implementation, the distance between the second outer surface and the first inner surface along the thickness direction of the electronic device is 3.15mm-3.25mm.

[0016] In one possible implementation, the speaker housing includes a first extension and a second extension connected to each other, the first extension extending along the length direction of the electronic device and the second extension extending along the width direction of the electronic device, the speaker unit being disposed at the connection between the first extension and the second extension, and both the first extension and the second extension having the rear acoustic cavity.

[0017] In one possible implementation, the speaker housing further includes a third extension that extends to the inner wall of the housing and corresponds to the sound outlet. A sound outlet channel is formed within the third extension, and the sound outlet channel connects the front sound cavity and the sound outlet.

[0018] In one possible implementation, a second annular seal is provided between the third extension and the housing, the second annular seal being located at the outlet of the sound outlet channel.

[0019] In one possible implementation, a dustproof net is provided at the outlet of the sound outlet channel.

[0020] In one possible implementation, a reinforcing member is further provided on the first outer surface, the reinforcing member being laid along the first outer surface.

[0021] In one possible implementation, flexible vibration damping elements are laid on both the second outer surface and the reinforcement.

[0022] In one possible implementation, the housing includes a bottom shell and a first sidewall, the first sidewall being arranged along the length of the electronic device, and the sound outlets being provided at both ends of the first sidewall.

[0024] Compared with the prior art, the electronic device of this application has the following advantages:

[0025] The electronic device of this application includes a housing and a speaker assembly. The housing serves as an integral frame with a sound outlet, which is the final channel for sound transmission. The speaker assembly is installed inside the housing and includes a speaker shell, which is disposed within the housing and forms an interconnected receiving cavity and a rear sound cavity. The receiving cavity houses the speaker driver, while the rear sound cavity plays a role in sound regulation. The first outer surface of the speaker shell is connected to the first inner surface of the housing. Simultaneously, an opening formed on the first outer surface communicates with the receiving cavity, and the speaker driver is located within the receiving cavity, with a diaphragm positioned on the side facing the opening. The diaphragm is spaced apart from the first inner surface of the housing, thus forming a front sound cavity, which then communicates with the sound outlet, ensuring that sound can be smoothly transmitted from the speaker driver to the outside. Therefore, compared to traditional solutions that require constructing the front and rear sound cavities within the speaker shell and then mounting the speaker shell onto the electronic device's housing, this application, while maintaining the same front sound cavity thickness, forms the front sound cavity of the speaker assembly through the space between the speaker driver's diaphragm and the first inner surface of the housing, eliminating the need for the original speaker shell wall thickness and saving space in the overall thickness direction of the electronic device. This application directly utilizes the space between the electronic device's casing and the speaker unit / speaker housing to form the front sound cavity, which makes the electronic device thinner and lighter, enhancing the product's competitiveness in terms of appearance and portability.

[0045] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0046] In this application, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral structure; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium, or an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0047] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0048] Because tablets need to house multiple core components such as the screen, battery, and processor, space is inherently limited. Existing speaker components often occupy too much space and frequently conflict with the layout of other components, which not only affects the tablet's slim and lightweight design but also limits the full performance of other components.

[0049] In related technologies, a plastic or metal shell is typically used to surround the diaphragm on the front side of the speaker driver, i.e., the side where the diaphragm emits sound, creating a closed or semi-closed space to form the front acoustic chamber. The rear acoustic chamber is usually located on the back of the speaker driver, opposite the front acoustic chamber. However, this structural design results in a relatively thick speaker assembly. A thicker speaker not only occupies more internal space but also affects the overall appearance design of the flat panel, leading to many shortcomings in the thickness design of speakers on the market, making it difficult to meet users' demands for thinner and lighter flat panel devices.

[0050] In view of this, some embodiments of this application provide an electronic device that can utilize the space between the electronic device’s housing and the speaker unit and speaker housing to form a front sound cavity, making the electronic device thinner and lighter, and improving the product’s competitiveness in terms of appearance and portability.

[0051] The present application will be described in detail below through specific embodiments:

[0052] The electronic device 100 in this application embodiment, such as Figure 1-13As shown, an electronic device 100 includes a housing 10 and a speaker assembly 20, and the housing 10 is provided with a sound outlet 11.

[0053] like Figure 3 As shown, the speaker assembly 20 includes a speaker housing 21, which is disposed inside the outer casing 10. The speaker housing 21 has a receiving cavity 211 and a rear sound cavity 212 that are interconnected. The speaker housing 21 includes a first outer surface 213, which is connected to the first inner surface 12 of the outer casing 10. The first outer surface 213 has an opening 2131 that is connected to the receiving cavity 211.

[0054] like Figure 4 As shown, the speaker assembly 20 also includes a speaker unit 22, which is disposed in the receiving cavity 211. The speaker unit 22 has a diaphragm 221 on the side facing the opening 2131. The diaphragm 221 is spaced apart from the first inner surface 12 to form a front sound cavity 23, which is connected to the sound outlet 11.

[0055] The electronic device 100 provided in this application embodiment includes a housing 10 and a speaker assembly 20. The housing 10 serves as an integral frame and has a sound outlet 11, which is the final sound transmission channel. The speaker assembly 20 is installed inside the housing 10 and includes a speaker shell 21 disposed within the housing 10. The speaker shell 21 forms an interconnected receiving cavity 211 and a rear sound cavity 212. The receiving cavity 211 is used to house the speaker driver 22, while the rear sound cavity 212 plays a certain role in adjusting the sound. The first outer surface 213 of the speaker shell 21 is connected to the first inner surface 12 of the housing 10. At the same time, the opening 2131 formed by the first outer surface 213 communicates with the receiving cavity 211. The speaker driver 22 is located inside the receiving cavity 211, and a diaphragm 221 is provided on the side facing the opening 2131. The diaphragm 221 is spaced apart from the first inner surface 12 of the housing 10 to form the front sound cavity 23, which is then connected to the sound outlet 11, ensuring that sound can be smoothly transmitted from the speaker unit 22 to the outside. Therefore, compared with the traditional solution that requires building the front sound cavity 23 and the rear sound cavity 212 inside the speaker housing 21 and then mounting the speaker housing 21 onto the housing 10 of the electronic device 100, this application, while ensuring the same thickness of the front sound cavity 23, forms the front sound cavity 23 of the speaker assembly 20 through the space between the diaphragm 221 of the speaker unit 22 and the first inner surface 12 of the housing 10, eliminating the original wall thickness of the speaker housing 21 and saving space in the thickness direction of the entire electronic device 100. This solution directly utilizes the space between the housing 10 of the electronic device 100 and the speaker unit 22 and speaker housing 21 to form the front sound cavity 23, making the electronic device 100 thinner and lighter, and improving the product's competitiveness in terms of appearance and portability.

[0056] It should be explained that the front sound cavity 23 is actually formed by the side wall of the receiving cavity 211, the first inner surface 12 of the outer shell 10 and the surface of the speaker unit 22 facing the opening 2131. Except for the connection with the sound outlet 11, the other components of the front sound cavity 23 are sealed.

[0057] In the diagram, the X direction represents the thickness of the electronic device 100, the Y direction represents the length of the electronic device 100, and the Z direction represents the width of the electronic device 100.

[0058] It should be noted that the electronic device 100 can be a tablet, mobile phone, or computer, etc. This embodiment will be described using a tablet as an example.

[0059] Furthermore, such as Figure 3 and Figure 4 As shown, the receiving cavity 211 extends through the thickness direction of the electronic device 100 so that the speaker housing 21 is arranged around the outer periphery of the speaker unit 22, and the rear sound cavity 212 is connected to the outer periphery of the speaker unit 22.

[0060] By extending the cavity 211 along the thickness direction of the electronic device 100, the speaker housing 21 is arranged around the outer periphery of the speaker unit 22, allowing the speaker unit 22 to be surrounded by the speaker housing 21 in all directions. The rear sound cavity 212 is connected to the outer periphery of the speaker unit 22. When the speaker unit 22 is working, part of the sound waves generated enter the rear sound cavity 212. Since the rear sound cavity 212 is connected to the outer periphery of the speaker unit 22, this space can be effectively utilized, allowing sound to propagate and reflect within it, thereby regulating the sound.

[0061] Moreover, since the rear sound cavity 212 is located on the outer periphery of the speaker unit 22 and is connected to the outer periphery of the speaker unit 22, the speaker assembly 20 is effectively compressed in the thickness direction. No additional independent cavity space is needed in the thickness direction, which directly reduces the thickness of the speaker assembly 20. The thinner speaker assembly 20 makes it possible to make the electronic device 100 thinner and lighter. In the case of limited internal space of the tablet, reducing the thickness of the speaker assembly 20 can leave more space for other components such as the battery 30 and the motherboard 50, or directly reduce the overall thickness of the tablet while keeping the internal components unchanged, thus meeting the user's demand for a thin and portable tablet.

[0062] In other possible implementations, when more space is needed in the horizontal direction, the cavity 211 can be arranged only on one side of the first inner surface 12 along the thickness direction of the electronic device 100, and the rear cavity 212 can be provided behind the speaker unit 22.

[0063] In some embodiments, such as Figure 4As shown, the first outer surface 213 is provided with a first annular seal 2132 around the edge of the opening 2131. The first annular seal 2132 abuts against the housing 10 so that a front sound cavity 23 is formed between the diaphragm 221 and the first inner surface 12.

[0064] A first annular seal 2132 is provided around the edge of the opening 2131 on the first outer surface 213. One side of the first annular seal 2132 is in close contact with the first outer surface 213 of the speaker assembly 20, and the other side is in close contact with the first inner surface 12 of the housing 10, effectively preventing air leakage between the diaphragm 221 and the housing 10. When the speaker unit 22 is working, the diaphragm 221 vibrates to produce sound. The close contact between the first annular seal 2132 and the housing 10 seals the space between the diaphragm 221 and the first inner surface 12 of the housing 10, thereby forming the front sound cavity 23. The sound propagates in this relatively closed front sound cavity 23, undergoes a series of reflections and resonances, and is then transmitted through the sound outlet 11.

[0065] The first annular seal 2132 ensures the good sealing performance of the front sound cavity 23, preventing sound leakage from the front sound cavity 23 to other areas inside the electronic device 100 during sound propagation. This reduces sound energy loss and interference, ensuring that the sound can be concentrated and effectively transmitted through the sound outlet 11, improving sound propagation efficiency and clarity. Simultaneously, the first annular seal 2132 not only provides a sealing function but also enhances the connection stability between the speaker assembly 20 and the housing 10 to a certain extent. The first annular seal 2132 fills the gap between the speaker assembly 20 and the housing 10, reducing component loosening caused by vibration or movement, and improving the overall reliability and durability of the electronic device 100.

[0066] The first annular seal 2132 can be made of rubber, plastic, metal, or composite materials, and the application does not impose any restrictions.

[0067] In this embodiment, as Figure 9 and Figure 10 As shown, the speaker housing 21 includes an upper shell 214 and a lower shell 215 connected to each other. The upper shell 214 and the lower shell 215 are arranged opposite each other along the thickness direction of the electronic device 100. The upper shell 214 is provided with a first stop portion 2141 facing the receiving cavity 211, and the lower shell 215 is provided with a second stop portion 2151 facing the receiving cavity 211. Along the thickness direction of the electronic device 100, the speaker unit 22 is disposed between the first stop portion 2141 and the second stop portion 2151 and abuts against the first stop portion 2141 and the second stop portion 2151 respectively.

[0068] The speaker housing 21 is formed by two parts: an upper shell 214 and a lower shell 215. The upper shell 214 and the lower shell 215 are connected to each other and are placed opposite each other along the thickness direction of the electronic device 100. The upper shell 214 has a first stop 2141 facing the receiving cavity 211, and the lower shell 215 also has a second stop 2151 facing the receiving cavity 211. From the thickness direction of the electronic device 100, the speaker unit 22 is precisely placed between the first stop 2141 and the second stop 2151, and abuts against the first stop 2141 and the second stop 2151 respectively.

[0069] Therefore, the first stop 2141 and the second stop 2151 can precisely define the position of the speaker driver 22 within the receiving cavity 211 of the speaker housing 21. During the production and assembly process, workers can quickly and accurately install the speaker driver 22 into place based on the position of the stop, avoiding problems such as abnormal sound propagation and decreased acoustic performance caused by installation position deviations. At the same time, the tight contact ensures that the speaker driver 22 will not shift during equipment operation, and can remain stable even when subjected to vibration or external impact, ensuring the stability and consistency of sound output.

[0070] Specifically, such as Figure 7 and Figure 9 As shown, the speaker assembly 20 includes a plurality of fasteners 24, which are arranged around the outer periphery of the speaker housing 21 and connect the speaker housing 21 to the first inner surface 12.

[0071] Multiple fasteners 24 are distributed around the outer periphery of the speaker housing 21, forming a uniform and stable connection structure, which greatly increases the connection strength between the speaker housing 21 and the first inner surface 12, and enables the speaker housing 21 to be subjected to relatively balanced tensile or compressive forces in all directions, thereby ensuring a stable and reliable connection with the first inner surface 12.

[0072] The fastener 24 can be a screw, bolt, stud, etc., and this embodiment does not specifically limit it. For example, the fastener 24 in this embodiment is a screw.

[0073] In one possible implementation, such as Figure 4 , Figure 5 and Figure 11 As shown, the receiving cavity 211 is a cuboid cavity, the speaker unit 22 is a cuboid structure, the long side of the speaker unit 22 extends along the length direction of the electronic device 100, the short side of the speaker unit 22 extends along the width direction of the electronic device 100, and the speaker housing 21 also includes a second outer surface 216 opposite to the first outer surface 213. Along the thickness direction of the electronic device 100, both the first outer surface 213 and the second outer surface 216 are located inside the receiving cavity 211.

[0074] The cavity 211 is designed as a cuboid cavity, which matches the shape of the cuboid speaker unit 22. This facilitates a compact and efficient layout within a limited space, making full use of the space inside the electronic device 100, and making the fit between the speaker unit 22 and the cavity 211 tighter, thus reducing unnecessary space waste.

[0075] The speaker housing 21 has a second outer surface 216 opposite to the first outer surface 213. Along the thickness direction of the electronic device 100, both the first outer surface 213 and the second outer surface 216 are located within the receiving cavity 211, so that the speaker housing 21 is completely enclosed within the receiving cavity 211. Along the thickness direction of the electronic device 100, the speaker unit 22 is not in contact with other components except for being connected to the speaker housing 21, which can provide all-round protection for the speaker unit 22 and prevent it from being interfered with and damaged by external factors.

[0076] In some embodiments, such as Figure 5-8 As shown, along the thickness direction of the electronic device 100, the distance (a+b+c) between the second outer surface 216 and the first inner surface 12 is 3.15mm-3.25mm.

[0077] Specifically, in this embodiment, along the thickness direction of the electronic device 100, the distance b between the diaphragm 221 and the first inner surface 12 is between 0.7mm and 0.8mm, the thickness c of the speaker unit 22 is 2.3mm, and the distance a between the surface of the speaker unit 22 away from the diaphragm 221 and the second outer surface 216 is 0.15mm. Therefore, the overall thickness of the speaker assembly 20 can be reduced to a minimum of 3.15mm. By reducing the thickness of the front acoustic cavity 23 without affecting sound propagation, the electronic device 100 can be made thinner and lighter, which is beneficial to the compactness and rationality of the overall structure.

[0078] In one possible implementation, such as Figure 3 and Figure 5 As shown, the speaker housing 21 includes a first extension 217 and a second extension 218 that are connected to each other. The first extension 217 extends along the length direction of the electronic device 100, and the second extension 218 extends along the width direction of the electronic device 100. The speaker unit 22 is disposed at the connection between the first extension 217 and the second extension 218. Both the first extension 217 and the second extension 218 have a rear sound cavity 212.

[0079] The speaker housing 21 is divided into a first extension 217 along the length direction of the electronic device 100 and a second extension 218 along the width direction, and a speaker unit 22 is provided at the connection between the two, forming an L-shaped structure. The L-shaped speaker assembly 20 can be well adapted to the shape of the electronic device 100, making full use of the corner space at the edge of the electronic device 100. The L-shaped structure can be arranged more flexibly at the edge of the electronic device 100 without occupying too much internal space. The L-shaped structure can fully adapt to the space of other components inside the electronic device 100, so that the speaker assembly 20 can be better integrated into the overall structure of the electronic device 100.

[0080] In other embodiments, depending on the construction and layout of the internal space, a conventional circular or square horn assembly 20 may also be used.

[0081] In one possible implementation, such as Figure 4 As shown, the speaker housing 21 also includes a third extension 219, which extends to the inner wall of the housing 10 and corresponds to the sound outlet 11. A sound outlet channel 2191 is formed in the third extension 219, which connects the front sound cavity 23 and the sound outlet 11.

[0082] The sound outlet channel 2191 effectively focuses and guides the sound in the front acoustic cavity 23 to the sound outlet 11, achieving directional sound propagation. The third extension 219, as part of the speaker housing 21, together with other extensions and the speaker unit 22, forms a more complete and stable structure. The connection between the third extension 219 and the inner wall of the housing 10 provides additional support points for the speaker housing 21, increasing the installation stability of the entire speaker assembly 20 in the electronic device 100. The sound outlet channel 2191, located in the third extension 219, ensures better dustproof and protective functions, better sealing performance, and reduces the possibility of dust, debris, etc., entering the speaker interior.

[0083] In one possible implementation, such as Figure 4 As shown, a second annular seal 2192 is provided between the third extension 219 and the outer casing 10, and the second annular seal 2192 is located at the outlet of the sound outlet channel 2191.

[0084] The second annular seal 2192 is located between the third extension 219 and the outer casing 10, and at the outlet of the sound outlet channel 2191. It can directly seal the interface between the sound outlet channel 2191 and the outside, forming an annular sealing structure around the outlet of the sound outlet channel 2191, effectively isolating the inside of the sound outlet channel 2191 from the external environment. The annular seal has a certain degree of elasticity and acts as a buffer between the third extension 219 and the outer casing 10, absorbing the vibrations generated when the speaker is working and the external vibrations that the electronic device 100 may be subjected to during use, thus enhancing the stability of the entire structure.

[0085] The second annular seal 2192 can be made of rubber, plastic, metal, or composite materials, and the application does not impose any restrictions.

[0086] Furthermore, a dustproof net is installed at the exit of the sound outlet channel 2191.

[0087] Thus, by setting a dustproof net at the outlet of the sound outlet channel 2191, it effectively blocks dust, hair, fibers and other tiny foreign objects from entering the sound outlet channel 2191 and the inside of the speaker, preventing dust and other foreign objects from adhering to the speaker diaphragm 221, so as not to change the mass and vibration characteristics of the diaphragm 221, thereby avoiding sound distortion, noise and other problems caused by foreign objects, ensuring that the sound can be transmitted clearly and accurately, and maintaining good sound quality.

[0088] In one possible implementation, such as Figure 4 As shown, a reinforcing member 2133 is also provided on the first outer surface 213, and the reinforcing member 2133 is laid along the first outer surface 213.

[0089] Thus, the reinforcing member 2133 increases the overall rigidity of the speaker housing 21, making the speaker less prone to deformation when subjected to external pressure, impact, or stress caused by speaker vibration during use. The reinforcing member 2133 alters the vibration characteristics of the speaker housing 21, effectively suppressing unnecessary resonance. When the speaker is operating, it reduces additional noise and vibration interference caused by housing vibration, resulting in a purer, clearer sound, improved sound quality, and prevention of sound distortion or noise caused by resonance, thus enhancing the audio experience.

[0090] Among them, the reinforcing member 2133 of this application is a reinforcing plate, on which round holes are evenly opened to enhance the connection strength between the reinforcing plate and the first outer surface 213.

[0091] In one possible implementation, flexible vibration damping elements are laid on both the second outer surface 216 and the reinforcement 2133.

[0092] The flexible vibration damper effectively isolates the vibrations generated by the speaker during operation from being transmitted to other components or the equipment housing 10. Simultaneously, the flexible vibration damper has excellent buffering performance, acting as a buffer when the equipment is subjected to external impacts or collisions, protecting the speaker housing 21, the reinforcing member 2133, and other internal components. Because the flexible vibration damper reduces unnecessary vibrations and noise, the sound emitted by the speaker is purer and not interfered with by noise generated by other vibrations.

[0093] The flexible vibration damping component can be made of rubber, silicone, sponge, foam, fiber, etc., and the flexible vibration damping component in this application is vibration damping foam.

[0094] In one possible implementation, such as Figure 5 As shown, the outer casing 10 includes a bottom casing 13 and a first sidewall 14. The first sidewall 14 is arranged along the length direction of the electronic device 100. Both ends of the first sidewall 14 are provided with sound outlet holes 11. The speaker assembly 20 includes two speakers, which are respectively disposed at both ends of the bottom casing 13 along the length direction of the electronic device 100 and close to the first sidewall 14. An angled region 2193 is formed between the first extension 217 and the second extension 218. The electronic device 100 also includes internal components. The angled region 2193 is used to accommodate a part of the internal components.

[0095] Thus, this design, with two speaker assemblies 20 at both ends along the length of the electronic device 100 and sound outlet holes 11 at both ends of the first sidewall 14, is suitable for horizontally oriented electronic devices 100. The distance between the two speakers allows for a better creation of a stereo sound field. An L-shaped speaker assembly 20 is formed between the first extension 217 and the second extension 218 and the speaker unit 22. The included angle region 2193 of the L-shaped speaker assembly 20 is used to accommodate a portion of the internal components, which makes full use of the internal space of the electronic device 100 and improves space utilization.

[0096] For example, such as Figure 12 As shown, the internal components include a battery 30, a motherboard 50, and a screen circuit board 40. They can be arranged in a reasonable layout with the speaker assembly 20. The edges of the L-shaped speaker assembly 20 are reasonably arranged with the edges of the electronic device 100. The included angle area 2193 of one L-shaped speaker assembly 20 can accommodate part of the structure of the battery 30, and the included angle area 2193 of the other L-shaped speaker assembly 20 can accommodate part of the structure of the screen circuit board 40, making the internal space more compact and reasonable.

[0097] In another possible implementation, such as Figure 13As shown, the housing 10 includes a bottom shell 13 and opposing second and third side walls. The second and third side walls are arranged along the length of the electronic device 100. The second and third side walls are provided with sound outlet holes 11 opposite to each other. The speaker assembly 20 includes two speakers 20, which are symmetrically arranged at both ends of the bottom shell 13 along the width of the electronic device 100 and respectively close to the second and third side walls. An angled region 2193 is formed between the first extension 217 and the second extension 218. The electronic device 100 also includes internal components, and the angled region 2193 is used to accommodate a part of the internal components.

[0098] For example, such as Figure 13 As shown, the internal components include a battery 30, a motherboard 50, and a screen circuit board 40, which can be arranged in a reasonable layout with the speaker assembly 20. The edges of the L-shaped speaker assembly 20 are reasonably arranged with the edges of the electronic device 100. The angle area 2193 between the two L-shaped speaker assemblies 20 can accommodate part of the structure of the screen circuit board 40. The battery 30 and the motherboard 50 are located above the L-shaped speaker assembly 20, making the internal space more compact and reasonable.

[0099] Thus, the two speakers are located at opposite ends of the tablet's width, close to the sound outlets 11 on the opposite second and third sidewalls. Suitable for vertical-screen electronic devices 100, the symmetrical distribution of the two speaker assemblies 20 provides better stereo sound in portrait mode. Sound is emitted from both sides of the tablet, resulting in better left and right channel separation when viewing stereo content in portrait mode, creating a more spatial audio environment and enhancing user immersion. Furthermore, the symmetrically distributed speaker assemblies 20 can be fitted with the screen circuit board 40, making the overall space more compact and efficient.
