For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "when," "when," or "in response to determination."

[0050] Figure 1 This is a schematic diagram of the structure of an electronic device according to an exemplary embodiment. Figure 2 This is a cross-sectional schematic diagram of an electronic device according to an exemplary embodiment. Figure 3 yes Figure 2 A magnified view of a portion of the image. (See attached image.) Figure 1 and Figure 2 As shown, the electronic device includes a battery cover 1, a screen cover 2, and a mid-frame 3. The battery cover 1 and screen cover 2 are assembled to form the internal space of the electronic device, where other electronic components and mechanical structures can be rationally arranged. For example, the mid-frame 3 can be located within this internal space. Based on this, the overall appearance of the electronic device has only one seam between the battery cover 1 and the screen cover 2, which reduces assembly gaps and minimizes the sense of disjointedness in the overall appearance, thus improving the aesthetics of the electronic device. Furthermore, since the number of assembled parts on the overall appearance is reduced, it is easier to achieve consistency in the materials used, further enhancing the aesthetics of the electronic device.

[0051] For example, the battery cover 1 may include a glass battery cover, and the screen cover 2 may include a glass cover, thereby forming the entire glass exterior of the electronic device through the glass battery cover and the glass cover, improving the feel, texture, and aesthetics. Moreover, based on the same glass material, a seamless and transparent effect can be achieved for the overall appearance, further reducing the sense of discontinuity in the device. In some embodiments, in the thickness direction of the electronic device, the projection of the screen cover 2 can cover the projection of the battery cover 1, for example, the projection of the screen cover 2 coincides with the projection of the battery cover 1, or the projection of the screen cover 2 is slightly larger than the projection of the battery cover 1. Based on this, when the user holds the electronic device and slides it smoothly from front to back, it will not scratch their hand, thus solving the problem of scratching the hand due to misalignment in the user's normal holding posture.

[0052] In the above embodiments, since there is an assembly gap between the battery cover 1 and the screen cover 2, in order to improve the sealing of the electronic device, such as Figure 3 and Figure 4As shown, the battery cover 1 includes a first sidewall surface 11, and the screen cover 2 includes a second sidewall surface 21, with the first sidewall surface 11 and the second sidewall surface 21 disposed opposite to each other. The electronic device also includes a sealant 4, at least a portion of which is disposed between the first sidewall surface 11 and the second sidewall surface 21 to bond the battery cover 1 and the screen cover, achieving a waterproof seal for the electronic device. The first sidewall surface 11 may be planar, or it may include a central plane and a chamfered plane on one side of the central plane; similarly, the second sidewall surface 21 may be planar, or it may include a central plane and a chamfered plane on one side of the central plane; the specific design can be customized as needed.

[0053] In some embodiments, such as Figure 4 As shown, the screen cover 2 includes a flat portion 22, a curved portion 23, and a vertical portion 24. The curved portion 23 connects the flat portion 22 and the vertical portion 24 to allow the screen cover 2 to bend towards the battery cover 1 in the thickness direction of the electronic device. The second sidewall surface 21 is the surface of the vertical portion 24 facing away from the curved portion 23. To avoid assembly interference, a certain gap is usually designed between the vertical portion 24 and the middle frame 3, generally requiring more than 0.2mm. However, this results in the vertical portion 24 lacking effective support, leading to decreased strength and reliability. Therefore, it is still based on... Figure 4 As shown, the electronic device also includes a buffer 5, which is disposed between the vertical portion 24 and the middle frame 3, and a portion of the sealant 4 is bonded to the buffer 5. Based on this, on the one hand, the buffer 5 can provide support for the vertical portion 24, improving its strength; on the other hand, by filling the gap between the vertical portion 24 and the middle frame 3, the buffer 5 can support and limit the sealant 4 when it is formed using dispensing or caulking adhesive, ensuring continuous adhesive lines. Since the sealant 4 can be formed in a single process, it is necessary to increase the overlapping area of ​​the buffer 5 with the middle frame 3 and the vertical portion 24, designing a larger buffer 5 to reduce manufacturing complexity.

[0054] In other embodiments, such as Figure 5As shown, the sealant 4 may include a first sealant 41 and a second sealant 42. The second sealant 42 is partially disposed between the first sidewall surface 11 and the second sidewall surface 21. The first sealant 41 is located between the second sealant 42 and the buffer member 5. The first sealant 41 can be bonded to the middle frame 3, the vertical part 24, the buffer member 5, and the second sealant 42 respectively. The first sealant 41 and the second sealant 42 can be formed through two processes. Thus, during subsequent assembly, after the buffer member 5 is assembled, the first sealant 41 located between the vertical part 24 and the middle frame 3 can be obtained first through a dispensing process. The first sealant 41 serves as a partial support for the vertical part 24. Subsequently, the second sealant 42 is formed. The first sealant 41 serves as a support and limit for the second sealant 42, ensuring the continuity of the adhesive line. This reduces the overlapping area of ​​the buffer member 5 with the middle frame 3 and the vertical part 24, reduces the assembly difficulty of the buffer member 5, and reduces the deformation caused by the force generated by the deformation of the buffer member 5.

[0055] In the above embodiments, such as Figure 6 As shown, at least a portion of the surface of the buffer 5 facing the vertical portion 24 is curved. Subsequent contact and interference between the curved portion and the vertical portion 24 helps to reduce the interference area, decrease the force exerted by the buffer 5 on the vertical portion 24, and lower the probability of damage to the screen cover 2. Specifically, the interference between the buffer 5 and the vertical portion 24 occurs in the width direction of the electronic device, i.e. Figure 4 and Figure 5 In the left and right direction, the interference width between the buffer 5 and the vertical part 24 is greater than or equal to 0.1 mm and less than or equal to 0.35 mm. This ensures that the buffer 5 can provide support for the vertical part 24, and avoids that the interference width is too large, which would cause the buffer 5 to exert too much force on the vertical part 24, affecting assembly and yield.

[0056] For example, such as Figure 6 As shown, the buffer 5 includes a square main body 51 and an arc-shaped protrusion 52 disposed on the square main body 51. The arc-shaped protrusion 52 abuts against the vertical part 24, and in the direction from the first side wall surface 11 to the second side wall surface 21, that is, in the direction from the battery cover 1 to the screen cover 2, the thickness of the arc-shaped protrusion 52 decreases. This allows the section of the arc-shaped protrusion 52 near the battery cover 1 to be designed to be relatively thick, ensuring that it can deform and abut against the vertical part 24, providing support and preventing the colloid from flowing freely. The section of the arc-shaped protrusion 52 away from the battery cover 1 is designed to be relatively thin, which helps to reduce the contact area between the buffer 5 and the vertical part 24 and reduce the force. For example, as... Figure 7As shown, in the direction from the first sidewall surface 11 to the first sidewall surface 21, that is, in the direction from the battery cover 1 to the screen cover 2, the thickness of the arc-shaped protrusion 52 first increases and then decreases, which helps to reduce the contact area between the buffer 5 and the vertical part 24 and reduce the force.

[0057] In some embodiments, the surface of the middle frame 3 facing the vertical portion 24 is planar, and the buffer member 5 is attached to the planar side of the middle frame 3. In other embodiments, the middle frame 3 is provided with a mounting groove, and the buffer member 5 may be partially disposed in the mounting groove, wherein the mounting groove may be a stepped groove or a recess, and the present disclosure does not limit the specific details.

[0058] In some embodiments, such as Figure 8 As shown, the curved portion 23 includes multiple arcuate regions, and the radii of these arcuate regions decrease from the flat portion 22 to the vertical portion 24. For example... Figure 6 As shown, the curved portion 23 includes a first arc region R1, a second arc region R2, and a third arc region R3. The second arc region R2 connects the first arc region R1 and the third arc region R3. The first arc region R1 connects to the flat portion 22, and the third arc region R3 connects to the vertical portion 24. The arc radii of the first arc region R1, the second arc region R2, and the third arc region R3 gradually decrease. This achieves a smooth transition between the vertical portion 24 and the flat portion 22. Furthermore, the increased radius of the first arc region R1 near the flat portion 22 visually reduces the black border of the screen.

[0059] like Figure 9 As shown, the battery cover 1 includes a bent portion 12, which includes a first sidewall surface 11. In the thickness direction of the electronic device, the sum of the height dimensions of the bent portion 23 and the vertical portion 24 is greater than twice or more than twice the height dimension of the bent portion 12, that is, H1≥2H2. This visually lengthens the height of the vertical portion 24, improves the aesthetics of the side of the electronic device, and also helps to reduce the black border of the screen.

[0060] In the above embodiments, such as Figures 10-13 As shown, the middle frame 3 includes a sound channel 31, and the sealant 4 includes a sealing break 43, which communicates with the sound channel 31. The electronic device also includes a sound module 6, which is disposed towards the interior of the sound channel 31 to pick up or output sound through the sound channel 31 and the sealing break 43. For example, the sound module 6 may include a microphone, which can pick up sound through the sound channel 31 and the sealing break 43; or the sound module 6 may include a speaker, which can output sound through the sound channel 31 and the sealing break 43.

[0061] The sound channel 31 may include a first opening 32, a second opening 32, and a third opening 34. The first opening 32 connects to the outside of the electronic device, the second opening 32 faces the sound module 6 to enable the sound module 6 to pick up or output sound, and the third opening 34 connects to the internal space of the electronic device. The electronic device also includes a waterproof and breathable membrane 7 disposed on the middle frame 3 and sealing the third opening 34. Thus, the waterproof and breathable membrane 7 enables communication between the sound channel 31 and the internal space of the electronic device, while simultaneously achieving a waterproof seal. Based on this, the sound channel 31 can simultaneously relieve pressure and propagate sound, which helps reduce the number of openings on the middle frame 3, improving the aesthetics of the electronic device and the strength of the middle frame 3. The waterproof and breathable membrane 7 can be disposed inside the third opening 34 or can cover the outside of the third opening 34, depending on the specific design requirements.

[0062] In the following embodiments, the sound module 6 can be a microphone, such as... Figure 11 As shown, the electronic device also includes a display panel 8 and a speaker 9. The display panel 8 is adhered to the inside of the screen cover 2, and the speaker 9 is attached to the non-display side of the display panel 8. The speaker 9 can be used to drive the display panel 8 and the screen cover 2 to vibrate and produce sound. Based on this, the sound output method of the speaker 9 can reduce the airflow fluctuations within the electronic device caused by the vibration of the speaker 9, and reduce the probability of airflow entering the microphone's sound channel 31 through the waterproof and breathable membrane 7 due to the vibration of the speaker 9, thus reducing the probability of the microphone picking up and generating airflow sound.
