DETAILED DESCRIPTION

[0038] The exemplary embodiments will be described in detail herein with reference to the accompanying drawings. The following description is presented in the context of the accompanying drawings in which the same numbers represent the same or similar elements throughout the several drawings. The implementations described in the following exemplary embodiments are not meant to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0039] In an electronic device with a voice function such as recording, calling, etc., a sound hole is usually arranged on the shell of the electronic device, and the sound outside the electronic device reaches a microphone for capturing sound through the sound hole, so as to realize sound collection.

[0040] However, in the related art, the sound hole is usually a single-end opening long channel, and a large amount of wind noise is generated during sound collection. In addition, when water enters the sound hole, the water is easily adsorbed in the channel of the sound hole and is difficult to drain, which greatly affects the sound collection effect and quality of the microphone.

[0041] To solve the above technical problems, the embodiments of the present disclosure provide a drainage structure and an electronic device. The drainage structure includes a first frame, a second frame, and a noise reduction assembly. The first frame is provided with a sound collection cavity. The second frame is arranged on the first frame. A drainage channel is formed between the first frame and the second frame. The noise reduction assembly is arranged between the drainage channel and the first frame, and the sound collection cavity and the drainage channel are communicated through the noise reduction assembly. The embodiments of the present disclosure arrange the drainage channel and the noise reduction assembly, so as to drain the water and achieve the waterproof effect. At the same time, the water and wind noise can be prevented from affecting the sound collection effect, and the sound collection quality and user experience are improved.

[0042] According to an exemplary embodiment, as shown in Figures 1-7 The embodiments of the present disclosure provide a drainage structure 200. The drainage structure 200 is arranged on the shell 101 of the electronic device 100, and the drainage structure 200 is arranged corresponding to the sound collecting piece 102 on the electronic device 100, so that the drainage structure 200 can be used to achieve the waterproof effect of the MIC module of the electronic device 100 and improve the sound collection quality.

[0043] The drainage structure 200 includes a first frame 210 and a second frame 220. The first frame 210 is provided with a sound collection cavity 211. The sound collection cavity 211 is arranged corresponding to the sound hole 1011 on the shell 101 of the electronic device 100, that is, the projection of the sound collection cavity 211 on the shell 101 at least partially coincides with the sound hole 1011. The sound collection cavity 211 is arranged on the side of the sound hole 1011 away from the sound collecting piece 102. The sound collecting piece 102 can be a sound collecting plate or other element for converting a sound signal into an electrical signal. After the sound airflow passes through the sound collection cavity 211 and the sound hole 1011, the sound airflow reaches the sound collecting piece 102, so as to realize sound collection.

[0044] The second frame 220 is arranged on the first frame 210 away from the shell 101, and a drainage channel 240 is formed between the second frame 220 and the first frame 210. The drainage channel 240 can be enclosed by a gap between the first frame 210 and the second frame 220, or part of the drainage channel 240 can be arranged in the first frame 210 and part of the drainage channel 240 can be arranged in the second frame 220, and the present embodiment does not make too many limitations on this. The drainage channel 240 can make the water entering the drainage channel 240 form a cycle and finally drain out of the drainage channel 240 without invading the sound hole 1011, so as to prevent the water from blocking the sound hole 1011 and affecting the sound collection effect.

[0045] The drainage structure 200 further comprises a noise reduction assembly 230 arranged between the drainage channel 240 and the first frame 210, and the sound collection cavity 211 and the drainage channel 240 are communicated through the noise reduction assembly 230. The noise reduction assembly 230 can block the water while not affecting the sound airflow, and the noise reduction assembly 230 can further form a plurality of small cavities (not shown in the figure) to buffer the wind noise through the cavities, so as to reduce the wind noise and improve the sound collection reliability and sound quality.

[0046] In the present embodiment, the drainage structure 200 is provided with the drainage channel 240 for drainage and waterproof, and the drainage channel 240 and the sound collection cavity 211 are communicated through the noise reduction assembly 230. The noise reduction assembly 230 can block the water to a certain extent and can also reduce the sound airflow, thereby improving the sound stability and sound quality.

[0047] In some embodiments, the drainage channel 240 comprises a channel body 241 and an opening 242. As shown in Figures 3-7 The channel body 241 is arranged between the first frame 210 and the second frame 220, and the opening 242 is arranged on the channel body 241, and the channel body 241 is communicated with the external environment through the opening 242. The channel body 241 can be enclosed by a gap between the first frame 210 and the second frame 220, or part of the channel body 241 can be arranged in the first frame 210 and part of the channel body 241 can be arranged in the second frame 220, and the present embodiment does not make too many limitations on this, and a person skilled in the art can arrange according to actual needs.

[0048] In one example, the number of openings 242 is one. That is, the channel body 241 is a one-way channel, and the water entering the channel body 241 through the opening 242 moves in the channel body 241 and then is discharged through the opening 242, or evaporates naturally during the movement in the channel body 241, thereby avoiding blocking the opening 242 and achieving the waterproof effect.

[0049] In another example, as shown in Figures 3-7As shown, the number of openings 242 is two. The openings 242 are arranged at both ends of the channel body 241, and the openings 242 at both ends of the channel body 241 can be used for drainage. After the water liquid in the external environment enters the channel body 241 through one of the openings 242, it will move along the channel body 241 due to factors such as vibration and surface tension of the liquid. Subsequently, the water liquid can be discharged to the outside of the channel body 241 through the other opening 242, or it can be discharged to the outside of the channel body 241 through the entering opening 242 after a period of movement, or it can evaporate naturally during movement. The movement direction and trajectory of the water liquid in the channel body 241 are affected by many factors, so the water liquid can also move irregularly. The embodiments of the present disclosure do not make too many restrictions on the movement mode of the water liquid in the channel body 241, as long as the water liquid can be discharged and will not interfere with the reception of the MIC module.

[0050] Of course, it can be understood that three, four or more openings 242 can also be arranged on the channel body 241. The multiple openings 242 can be uniformly or non-uniformly distributed along the extension direction of the channel body 241, and the multiple openings 242 can be arranged on the same straight line or staggered with each other. The embodiments of the present disclosure do not make too many restrictions thereon, and those skilled in the art can adjust them according to actual needs.

[0051] In some embodiments, the channel body 241 includes multiple connection segments, and adjacent two connection segments have a preset included angle. The preset included angles of adjacent two connection segments between different connection segments can be the same or different, and the embodiments of the present disclosure do not make too many restrictions thereon. By arranging the channel body 241 to include multiple connection segments with included angles, the total length of the channel body 241 can be extended in a limited space, so that the water liquid is less likely to reach the sound cavity 211 when moving in the channel body 241. In addition, by extending the total length of the channel body 241, the volume of the channel body 241 can be increased to improve the drainage and waterproof performance of the drainage structure 200.

[0052] In one example, the channel body 241 includes three connection segments. As shown in FIG. 6, the channel body 241 includes a first connection segment 2411, a second connection segment 2412 and a third connection segment 2413. The first connection segment 2411 and the second connection segment 2412 are arranged at an included angle a, and the second connection segment 2412 and the third connection segment 2413 are arranged at an included angle β. Figures 3-7As shown, the connecting segments include a first segment 2411, a second segment 2412, and a third segment 2413, which are sequentially connected. The axial direction of the second segment 2412 is parallel to the surface of the noise reduction assembly 230 close to the second frame 220, the axial direction of the first segment 2411 is perpendicular to the axial direction of the second segment 2412, and the axial direction of the first segment 2411 is parallel to the axial direction of the third segment 2413. The three connecting segments together form a channel body 241 in the shape of a "concave" character, thereby ensuring that the total length of the channel body 241 is extended and the waterproof effect is improved, and at the same time, the water in the channel body 241 is not difficult to drain due to the excessively tortuous internal structure of the channel body 241.

[0053] In some embodiments, the drainage channel 240 is provided with a drainage auxiliary structure. The drainage auxiliary structure includes a guide portion and / or a textured portion (not shown in the figure). The guide portion is arranged at the opening 242 to guide the water, so that the water at the opening 242 flows into the channel body 241 or the water in the channel body 241 is drained, thereby avoiding the water from blocking the opening 242 and affecting the sound quality. The textured portion is arranged inside the channel body 241, and the textured portion has a high roughness, thereby avoiding the water from being absorbed on the inner wall of the channel body 241 in the form of film, and facilitating the water to be drained to the outside as soon as possible, so as to avoid the residual water in the drainage channel 240 affecting the drainage performance. In one example, the drainage auxiliary structure includes the guide portion arranged at the opening 242 to improve the drainage speed; in another example, the drainage auxiliary structure includes the textured portion arranged inside the channel body 241 to avoid the water from being absorbed on the inner wall of the channel body 241; and in yet another example, the drainage auxiliary structure includes the guide portion arranged at the opening 242 and the textured portion arranged inside the channel body 241, thereby improving the overall drainage and waterproof performance of the drainage structure 200.

[0054] In some embodiments, the cross-sectional area of the opening 242 is greater than the cross-sectional area of the channel body 241. By setting the cross-sectional area of the opening 242 to be greater than the cross-sectional area of the channel body 241 and arranging the guide portion, the water on the surface of the opening 242 can be effectively guided to the channel body 241, thereby avoiding the water from blocking the opening 242 and causing the sound quality to decrease.

[0055] In addition, the shape of the opening 242 can include, but is not limited to, a circular shape, a rectangular shape, an elliptical shape, a water droplet shape, an irregular shape, and the like. Taking the rectangular shape of the opening 242 as an example, the width of the opening 242 ranges from 0.8 mm to 2 mm, and the length ranges from 6 mm to 20 mm. Of course, it can be understood that a person skilled in the art can set the shape and size of the opening 242 according to actual needs, and the embodiments of the present disclosure do not make too many limitations in this regard.

[0056] In some embodiments, the guide portion includes a guide slope. By setting a guide slope in the form of a slope, draft angle, or the like at the opening 242, the flow of water can be facilitated, the opening 242 can be prevented from being blocked, and the drainage efficiency of the drainage structure 200 can be improved.

[0057] In some embodiments, the roughness of the textured portion is greater than the roughness of the inner surface of the opening 242. By setting the roughness of the textured portion to be greater than the roughness of the inner surface of the opening 242, water absorption on the inner wall of the channel body 241 can be avoided, and water can be drained as soon as possible. The textured portion can be in the form of a stripe structure, a mesh structure, frosted glass, or the like. The roughness of the inner surface of the channel body 241 can be increased by laser engraving, spraying, or the like, so that the roughness range is Ra0.8-Ra2.5. It should be noted that the shape, roughness, process, and the like of the textured portion can be adjusted by those skilled in the art, and the present disclosure does not make too many limitations thereon. Those skilled in the art can select according to actual needs.

[0058] In some embodiments, the noise reduction assembly 230 includes a plurality of noise reduction pieces (not shown in the figure). The plurality of noise reduction pieces are arranged in layers, and adjacent two noise reduction pieces are fixedly connected. The fixed connection between the noise reduction pieces can be achieved by using a method such as adhesive bonding, welding, or fastening. The present disclosure does not make too many limitations thereon, and those skilled in the art can select according to actual needs.

[0059] In one example, the noise reduction piece includes a metal mesh. The number of layers of the metal mesh of the noise reduction assembly 230 is 2-6 layers, the thickness of the noise reduction assembly 230 ranges from 0.4 mm to 2.0 mm, and the material of the metal mesh can be stainless steel, such as 316L, 316, 304, or the like. The present disclosure does not make special limitations on the specific size and material of the metal mesh, and those skilled in the art can set according to actual needs.

[0060] In one example, the pore size of the metal mesh ranges from 0.01 mm to 0.2 mm, the wire diameter of the metal mesh ranges from 0.01 mm to 0.2 mm, and the equivalent pore size is further reduced after the multilayer metal mesh is stacked. A plurality of small cavities are formed between the metal mesh and the first frame 210 and the second frame 220, which can weaken the wind noise of the sound, thereby improving the sound quality. The equivalent acoustic resistance of the stacked multilayer metal mesh ranges from 200 to 800 Rayls.

[0061] In some embodiments, the first frame 210 further includes a mounting cavity 212. As shown in FIG. 2, the mounting cavity 212 is arranged on the first frame 210, and the second frame 220 is arranged in the mounting cavity 212. The mounting cavity 212 can be arranged on the first frame 210 in the form of a hole, a recess, or the like. The mounting cavity 212 can be arranged on the first frame 210 in the form of a hole, a recess, or the like. The mounting cavity 212 can be arranged on the first frame 210 in the form of a hole, a recess, or the like. Figures 3-7As shown, the noise reduction assembly 230 is arranged in the mounting cavity 212, the mounting cavity 212 is arranged on one side of the first frame 210 close to the second frame 220, the mounting cavity 212 is in communication with the sound collecting cavity 211, and the diameter of the mounting cavity 212 is greater than or equal to the diameter of the sound collecting cavity 211, and meanwhile, the diameter of the noise reduction assembly 230 is also greater than or equal to the diameter of the sound collecting cavity 211, so as to ensure the connection stability and noise reduction reliability of the noise reduction assembly 230.

[0062] In one example, the distance between the noise reduction assembly 230 and the mounting cavity 212 ranges from 0.05 mm to 0.2 mm, and the noise reduction assembly 230 and the mounting cavity 212 are fixed by means of back glue, point glue, etc. Of course, it can be understood that those skilled in the art can also select other connection modes to fixedly connect the noise reduction assembly 230 and the mounting cavity 212, and the specific connection mode between the noise reduction assembly 230 and the mounting cavity 212 is not limited too much in the embodiment of the present disclosure, and those skilled in the art can select according to actual needs.

[0063] In some embodiments, the drainage structure 200 further comprises a waterproof piece 250. As shown, Figures 3-7 The waterproof piece 250 is arranged between the drainage channel 240 and the first frame 210, the sound collecting cavity 211 and the drainage channel 240 are in communication through the waterproof piece 250, and the waterproof piece 250 and the noise reduction assembly 230 are arranged on the same plane. Among them, the waterproof piece 250 is a waterproof and breathable film, such as a polytetrafluoroethylene film, which is used to prevent water from entering the sound collecting cavity 211, while improving waterproofness without blocking sound airflow, so that the sound collecting piece 102 can normally collect sound.

[0064] In some embodiments, the waterproof piece 250 is arranged side by side with the noise reduction assembly 230. By arranging the noise reduction assembly 230 and the waterproof piece 250 at the same time, the waterproof and noise reduction effects of the drainage structure 200 can be further improved, and the sound collecting quality and user experience can be improved. Among them, as shown in the orientation, Figures 5-6 The waterproof piece 250 is arranged side by side with the noise reduction assembly 230, which means that they are located on the same horizontal plane.

[0065] In one example, the first frame 210 comprises a sound collecting cavity 211, and the waterproof piece 250 and the noise reduction assembly 230 are arranged correspondingly with the sound collecting cavity 211. As shown, Figure 5 The waterproof piece 250 and the noise reduction assembly 230 are arranged on one side of the drainage channel 240 close to the sound collecting cavity 211, and the sum of the cross-sectional areas of the waterproof piece 250 and the noise reduction assembly 230 is greater than or equal to the cross-sectional area of the sound collecting cavity 211, so as to ensure the structural reliability of the waterproof piece 250 and the noise reduction assembly 230.

[0066] In another example, the first frame 210 includes a plurality of sound receiving cavities 211, and the waterproof member 250 and the noise reduction assembly 230 are each arranged corresponding to one sound receiving cavity 211. As shown in Figure 6 The sound receiving cavities 211 include a first sound receiving cavity 2111 and a second sound receiving cavity 2112, which are arranged side by side. The noise reduction assembly 230 is arranged on one side of the drainage channel 240 close to the first sound receiving cavity 2111, and the waterproof member 250 is arranged on the other side of the drainage channel 240 close to the second sound receiving cavity 2112. The diameter of the noise reduction assembly 230 is greater than or equal to the diameter of the first sound receiving cavity 2111, and the diameter of the waterproof member 250 is greater than or equal to the diameter of the second sound receiving cavity 2112.

[0067] Of course, it can be understood that the number of the waterproof member 250 and the noise reduction assembly 230 is only one in the embodiment of the present disclosure, and the number of the waterproof member 250 and the noise reduction assembly 230 can be increased according to actual needs in actual production, and the arrangement order of the waterproof member 250 and the noise reduction assembly 230 can be changed. The present disclosure does not make too many limitations, and the person skilled in the art can select according to actual needs.

[0068] In some embodiments, the first frame 210 and the second frame 220 are an integral structure. In order to simplify the installation and production process, the first frame 210 and the second frame 220 shown in Figures 3-6 may be arranged as an integral structure, that is, the drainage frame 201 shown in Figure 7 By arranging the first frame 210 and the second frame 220 as an integral structure, the process can be effectively simplified, the production cost can be reduced, and the structural stability and reliability of the drainage structure 200 can be improved, which is convenient for maintenance and replacement of the drainage structure 200.
