Detailed Implementation

[0028] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0029] For example, mobile phones and other electronic devices typically have microphones. However, current methods for sealing and fixing microphones suffer from complex assembly and large space requirements. For instance, an electronic device in this technology includes a mid-frame, which comprises a support portion and a frame surrounding the support portion. When fixing the microphone to the side frame, a silicone component is first attached to the frame using adhesive, and then a cantilever structure is screwed onto the support portion. The cantilever structure presses the silicone component firmly, thereby achieving a sealed fixation of the microphone. However, this sealing and fixing method is complex to assemble, and both the adhesive and the cantilever structure result in significant space occupation within the electronic device.

[0030] To address the aforementioned technical issues, this disclosure provides a mid-frame assembly. The connecting portion of a seal is fixedly connected to the edge of the mid-frame. A groove is provided on the sealing portion of the seal corresponding to the microphone position, and the microphone is located within the groove. The seal secures the microphone to the edge of the frame. This not only simplifies the assembly of the mid-frame assembly, thereby improving assembly efficiency and replacing the adhesive backing method, but also saves materials. This effectively reduces assembly costs and minimizes the space occupied by the seal within the electronic device's internal space.

[0031] An exemplary embodiment of this disclosure provides a mid-frame component, such as Figure 1 As shown, the mid-frame assembly 1 includes a mid-frame 10, a microphone, and a seal 16. The mid-frame 10 includes a support portion 11 and a border 12 surrounding the support portion 11. The seal 16 is used to seal and secure the microphone to the border 12. Exemplarily, the border 12 surrounding the support portion 11 includes a top border 12, a side border 12, and a bottom border 12, and the microphone can be sealed and secured to the top border 12, the side border 12, or the bottom border 12 by the seal 16.

[0032] Combination Figure 2 and Figure 3 The sealing element 16 includes a connecting portion 161 and a sealing portion 162. The connecting portion 161 is fixedly connected to the frame 12, and the sealing portion 162 has a groove 1621 corresponding to the microphone position, with the microphone located within the groove 1621. This arrangement simplifies the assembly of the mid-frame assembly 1, thereby improving assembly efficiency. Furthermore, in this embodiment, the mid-frame assembly 1 eliminates the need for adhesive backing when sealing and fixing the microphone, saving materials and effectively reducing assembly costs while also minimizing the space occupied by the sealing element 16 within the electronic device. Moreover, compared to a cantilever structure, the sealing element 16 in this embodiment has higher structural strength, improving the reliability of the mid-frame assembly 1 and facilitating a thinner design for the sealing element 16, further reducing its space occupation within the electronic device.

[0033] Combination Figure 2 and Figure 3 In one embodiment, a receiving groove 121 is provided on the inner side of the frame 12, the microphone is disposed at the bottom of the receiving groove 121, and the connecting part 161 is connected to the side wall of the receiving groove 121. This design makes the structure of the middle frame assembly 1 more compact, thereby further reducing the internal space occupied by the electronic device and facilitating the thinning or miniaturization of the electronic device.

[0034] Combine, Figure 3 In one embodiment, a protrusion 125 protrudes outward from the inner surface of the frame 12. The protrusion 125 includes a first outer surface of the frame 12 opposite to the frame 12 connected to the protrusion 125, and a second outer surface connected to the first outer surface, the second outer surface being away from the support portion 11. The receiving groove 121 is recessed inward from the first outer surface and extends through the second outer surface. This arrangement facilitates the assembly of the seal 16 and the microphone, thereby further improving the assembly efficiency of the mid-frame assembly 1. Furthermore, it not only provides more connection area for the seal 16, effectively improving the stability of the seal 16's fixation, but also enhances the structural strength of the frame 12 and reduces the occupancy of the receiving groove 121 on the frame 12, thereby further improving the reliability of the mid-frame assembly 1.

[0035] In one embodiment, the receiving groove 121 includes a first groove and a second groove. The second groove is disposed at the bottom of the first groove, and the microphone is disposed at the bottom of the second groove. The connecting part 161 is connected to the side wall of the first groove, and the sealing part 162 is adapted to the surface of the bottom of the receiving groove 121 on the surface of the second groove. This design can further improve the sealing and fixing effect of the microphone.

[0036] Combination Figure 2 and Figure 3 In one embodiment, a first mating part is provided on the connecting part 161, and a second mating part is provided on the side wall of the receiving groove 121. The first and second mating parts cooperate to fix the sealing member 16 to the frame 12. Exemplarily, the first mating part may be a mounting hole, and the second mating part may be a screw or bolt for locking; the second mating part may also be a slot 122, and the first mating part may be a buckle adapted to the slot 122, etc., without specific limitation. This design can effectively improve the stability of the sealing member 16, thereby not only improving the sealing and fixing effect of the microphone, but also improving the reliability of the middle frame assembly 1.

[0037] Combination Figure 2 and Figure 3In one embodiment, slots 122 are provided on the two opposite sidewalls of the receiving groove 121, forming a second mating part. A locking block 163 is provided on the connecting part 161 corresponding to the position of each slot 122, forming a first mating part. The locking block 163 engages with the slot 122, i.e., it engages with the slot 122, thereby fixing the seal 16 to the frame 12. This arrangement simplifies the structure of the first and second mating parts, facilitating production and processing. It also simplifies the assembly of the middle frame assembly 1, further improving the assembly efficiency of the middle frame assembly 1.

[0038] In one embodiment, the connecting portion 161 includes a plastic structural component, and the sealing portion 162 includes a silicone structural component. Exemplarily, the connecting portion 161 and the sealing portion 162 can be separate structures connected by adhesive or other means, or they can be integrally formed by two-material injection molding. The plastic connecting portion 161 is used to connect to the frame 12, and the silicone sealing portion 162 is used to seal and fix the microphone. When the sealing portion 16 is connected to the middle frame 10, the microphone and the sealing portion 162 have an interference fit. This design simplifies the method of sealing and fixing the microphone, thereby improving the assembly efficiency of the middle frame assembly 1. Furthermore, the sealing portion 16 is lightweight, which is beneficial for lightweight design of electronic devices, while also possessing high structural strength to prevent breakage due to external forces. This not only effectively improves the reliability of the sealing portion 16 but also enables a thinner design of the sealing portion 16, further reducing its footprint within the internal space of the electronic device.

[0039] In one embodiment, a groove-shaped structure is provided on the surface of the connecting portion 161 facing the sealing portion 162, and a snap-fit ​​structure adapted to the groove-shaped structure is provided on the sealing portion 162, the snap-fit ​​structure snapping into the groove-shaped structure. Thus, in the two-material injection molding of the sealing member 16, this arrangement improves the tightness of the connection between the connecting portion 161 and the sealing portion 162, thereby effectively improving the structural reliability of the sealing member 16.

[0040] In one embodiment, the frame 12 includes a side frame 12, on which the microphone is disposed. This improves the sound pickup effect of the electronic device. By sealing and fixing the microphone to the side frame 12 with the aforementioned sealing member 16, the sealing effect of the microphone is improved, thereby effectively improving the reliability of the electronic device. At the same time, it also reduces the space occupied by the side frame 12, which is conducive to the realization of more functions of the electronic device.

[0041] Combination Figure 3In one embodiment, the bottom of the receiving groove 121 includes a first edge 123 and a second edge 124. The first edge 123 is parallel to and connected to the support portion 11. Along a direction perpendicular to the support portion 11, the bottom of the receiving groove 121 gradually slopes outward from the first edge 123 to the second edge 124 towards the outside of the frame 12. This arrangement, on the one hand, increases the area of ​​the bottom of the receiving groove 121, thereby increasing the volume of the sealing portion 162 and effectively improving the sealing effect on the microphone. On the other hand, by making the bottom of the receiving groove 121 gradually slope outward from the first edge 123 to the second edge 124 along a direction perpendicular to the support portion 11 towards the outside of the frame 12, it facilitates the assembly of the microphone and the sealing element 16, thereby improving the ease and efficiency of assembling the mid-frame assembly 1.

[0042] Combination Figure 2 and Figure 3 In one embodiment, a sound pickup channel is provided on the frame 12. The first port 142 of the sound pickup channel is connected to a microphone, and the second port 131 of the sound pickup channel is disposed on the outer surface of the frame 12. The microphone picks up sound through the second port 131 on the outer surface of the frame 12, thereby ensuring the microphone's sound pickup effect. This not only improves the reliability of the electronic device but also enhances the user experience.

[0043] Combination Figure 4 and Figure 5 In one embodiment, the middle frame 10 includes a connected metal outer frame 13 and a plastic inner frame 14. This allows the metal outer frame 13 to function as an antenna for the electronic device, enabling the expansion of more functions of the electronic device by reducing its footprint within the device's internal space. The plastic inner frame 14 provides insulation for the metal outer frame 13, preventing it from affecting the antenna performance of the electronic device.

[0044] Corresponding to the microphone position, a cavity 141 is provided on the surface of the plastic inner frame 14 facing the metal outer frame 13. The cavity 141 forms a sound pickup channel. The first port 142 of the sound pickup channel is located at the bottom of the cavity 141, and the second port 131 of the sound pickup channel is located on the metal outer frame 13. This arrangement simplifies the construction of the sound pickup channel and facilitates production and processing.

[0045] Combination Figure 2 and Figure 3 In one embodiment, the mid-frame assembly 1 further includes a circuit board assembly, which is fixed to the frame 12. The microphone is connected to the circuit board, and a portion of the circuit board assembly extends out of the recess 1621. By setting the circuit board assembly, the microphone is electrically connected to the motherboard of the electronic device, thereby enabling control of the microphone.

[0046] Combination Figure 2 andFigure 3 In one embodiment, the circuit board assembly includes a flexible circuit board 15 and a reinforcing plate. The flexible circuit board 15 includes a connected body portion 151 and an extension portion 152. The body portion 151 is located between the microphone and the frame 12 and is connected to the microphone. Exemplarily, the microphone is soldered to the body portion 151 of the flexible circuit board 15. The extension portion 152 extends from a recess 1621 to connect to the motherboard of the electronic device.

[0047] A reinforcing plate is disposed between the body portion 151 and the frame 12. The reinforcing plate includes a first surface and a second surface facing away from each other. The first surface is connected to the body portion 151, for example, by means of adhesive backing. The second surface is connected to the middle frame 10, also for example, by means of adhesive backing. By providing the reinforcing plate, the structural strength of the flexible circuit board 15 can be improved, thereby facilitating the assembly of the flexible circuit board 15 and the microphone, and improving the stability of the connection between the two, thus enhancing the reliability of the middle frame assembly 1.

[0048] This configuration makes the structure of the mid-frame component 1 more compact, thereby further reducing the space occupied inside the electronic device.

[0049] Combination Figure 3 In one embodiment, a through hole 153 is provided on the circuit board assembly corresponding to the first port 142 of the pickup channel. The through hole 153 is used to connect the microphone to the first port 142 of the pickup channel. This ensures the microphone's pickup effect.

[0050] Combination Figure 1 and Figure 3 In one embodiment, a limiting groove 143 is provided on the support portion 11, and at least a portion of the extension portion 152 extending out of the groove 1621 is disposed in the limiting groove 143. Exemplarily, only a portion of the extension portion 152 of the flexible circuit board 15 may be disposed in the limiting groove 143, while another portion of the extension portion 152 is used to connect to the motherboard of the electronic device. Alternatively, all of the extension portions 152 may be disposed in the limiting groove 143, and the extension portion 152 may be connected to the motherboard of the electronic device via an electrical connection portion 161, such as a circuit board.

[0051] This design, on the one hand, avoids damage to the extension 152 caused by compression between the seal 16 and the support 11, thereby improving the reliability of the middle frame assembly 1. On the other hand, it also makes the structure of the middle frame assembly 1 more compact.

[0052] In one embodiment, the limiting groove 143 is disposed on the plastic inner frame 14 of the middle frame 10, which facilitates the processing of the limiting groove 143 and improves the production efficiency of the middle frame assembly 1.

[0053] In one embodiment, the edge of the connecting portion 161 of the sealing member 16 is adapted to the surface of the support portion 11. For example, when a stepped structure is provided on the support portion 11 at the position corresponding to the connecting portion 161, a concave structure adapted to the stepped structure is provided on the connecting portion 161, so that the concave structure is engaged with the stepped structure, thereby achieving a tight connection between the sealing member 16 and the middle frame 10. In this way, the sealing and fixing effect of the microphone can be improved, and the structural compactness of the middle frame assembly 1 can be improved.

[0054] An exemplary embodiment of this disclosure provides an electronic device, which may be a mobile device such as a mobile phone (e.g., a foldable phone), a tablet computer, a laptop computer, a PDA, an in-vehicle electronic device, a wearable device, an ultra-mobile personal computer (UMPC), a netbook, or a personal digital assistant (PDA), or a non-mobile device such as a personal computer (PC), a television (TV), an ATM, or a self-service machine.

[0055] like Figure 1 , Figure 2 and Figure 3 As shown, the electronic device includes the mid-frame assembly 1 as described above. The mid-frame assembly 1 includes a mid-frame 10, a microphone, and a seal 16. The mid-frame 10 includes a support portion 11 and a frame 12 surrounding the support portion 11. The seal 16 is used to seal and fix the microphone to the frame 12. The seal 16 includes a connecting portion 161 and a sealing portion 162. The connecting portion 161 is fixedly connected to the frame 12, and the sealing portion 162 has a groove 1621 corresponding to the microphone position, with the microphone located within the groove 1621.

[0056] This design simplifies the assembly of the mid-frame assembly 1, improving assembly efficiency. Furthermore, in this embodiment, the mid-frame assembly 1 eliminates the need for adhesive backing when sealing and fixing the microphone, saving materials and reducing assembly costs. This also minimizes the space occupied by the seal 16 within the electronic device. Moreover, compared to overhanging structures, the seal 16 in this embodiment has higher structural strength, improving the reliability of the mid-frame assembly 1 and facilitating a thinner design, further reducing its impact on the internal space of the electronic device.
