The implementations described in the following exemplary examples do not represent all implementations consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the application, as detailed in the claims that follow.

In a first aspect, the present application provides a housing assembly 10. Referring to fig. 2, the housing assembly 10 is used to mount the microphone 20. Referring to fig. 3, the housing assembly 10 may include a middle frame 100, and the middle frame 100 is provided with a sound guide channel 110 for transmitting sound. Specifically, the sound guide channel 110 can be used to transmit the sound outside the middle frame 100 to the microphone 20 inside the middle frame 100 through the sound guide channel 110.

The middle frame 100 may have a first surface 120, a second surface 130 opposite to the first surface 120, and a surface 140 connecting the first surface 120 and the second surface 130, the first surface 120 may be used for disposing the microphone 20, and two ends of the sound guide channel 110 may respectively penetrate through the first surface 120 and the surface 140. The appearance surface 140 may be: when the middle frame 100 is assembled with the cover plate, the display screen 30, and the like, all surfaces of the middle frame 100 are exposed. The two ends of the sound guiding channel 110 are disposed to respectively penetrate the first surface 120 and the outer surface 140 without penetrating the second surface 130, so that when the electronic device 1 is assembled, the display screen 30 can be mounted on the side of the middle frame 100 where the second surface 130 is located, and the reliable connection between the display screen 30 and the second surface 130 can be ensured because no opening is disposed on the second surface 130. And the second surface 130 is not provided with an opening, compared with the second surface 130 provided with an opening, the phenomenon that the display screen 30 is cracked and damaged due to stress concentration at the opening when the electronic device 1 falls can be avoided. Preferably, the second surface 130 may be a plane without openings to avoid stress concentration points.

The sound guide channel 110 may include a first channel 111 and a second channel 112, and the first channel 111 may be communicated with the second channel 112 and disposed to be bent with respect to the second channel 112. The sound guide channel 110 is provided with the first channel 111 and the second channel 112 which are arranged in a bending way, so that compared with the situation that only one straight-tube-shaped channel is arranged, dust entering the sound guide channel 110 can be blocked at the corner between the first channel 111 and the second channel 112, the amount of dust transmitted backwards is reduced, and the sound collection quality of the microphone 20 is further guaranteed.

The middle frame 100 may have a first inner wall surface 150 forming the first passage 111, and a second inner wall surface 160 forming the second passage 112, at least one of the first inner wall surface 150 and the second inner wall surface 160 may be used to mount the dust guard 200. Thus, dust entering the sound guide channel 110 is blocked not only by the corners of the first channel 111 and the second channel 112, but also by the dust-proof member 200, so that the sound quality of the microphone 20 can be further ensured. The first channel 111 may be close to the first surface 120 of the microphone 20, and the second channel 112 may be close to the external surface 140, at this time, the first inner wall surface 150 forming the first channel 111 may be used to mount at least two dust-proof pieces 200, so that after dust enters the sound guide channel 110, the dust will be blocked by the corners of the second channel 112 and the first channel 111 first, and then by at least two dust-proof pieces 200 in the first inner wall surface 150, so that the amount of dust reaching the dust-proof pieces 200 will be greatly reduced, the impact force of dust received by the dust-proof pieces 200 can be reduced, and the service life of the dust-proof pieces 200 can be prolonged.

In an exemplary embodiment, referring to fig. 4, the first channel 111 may include a first sub-channel 1111 adjacent to the first surface 120, a second sub-channel 1112 adjacent to the second channel 112, and a third sub-channel 1113 located between the first sub-channel 1111 and the second sub-channel 1112, the first inner wall surface 150 may include a first sub-wall surface 151 forming the first sub-channel 1111, a second sub-wall surface 152 forming the second sub-channel 1112, a third sub-wall surface 153 forming the third sub-channel 1113, a first step surface 154 connected between the third sub-wall surface 153 and the first sub-wall surface 151 in a bending manner, and a second step surface 155 connected between the third sub-wall surface 153 and the second sub-wall surface 152 in a bending manner, and the first step surface 154 and the second step surface 155 may be respectively used for installing two dust-proof members 200. The first inner wall surface 150 is provided to include a first step surface 154 and a second step surface 155, and two dust-proof pieces 200 are installed through the first step surface 154 and the second step surface 155, on one hand, the step surfaces can play a positioning effect on the installation of the dust-proof pieces 200, and the assembly accuracy of the dust-proof pieces 200 is improved; on the other hand, the simple structure of the step surface is beneficial to the development of the connection work of the step surface and the dustproof piece 200; for example, glue may be applied directly to the step surface and/or the dust guard 200 and the step surface and the dust guard 200 may be connected via the glue.

The first step surface 154 and the second step surface 155 may both face the first face 120. It should be noted that, the first step surface 154 and the second step surface 155 facing the first surface 120 may be: when viewed from the side of the middle frame 100 where the first surface 120 is located toward the sound guide passage 110, the first step surface 154 and the second step surface 155 can be seen. In this way, the first step surface 154 and the second step surface 155 are both disposed facing the first surface 120, so that the two dust-proof components 200 can be mounted on the side where the first surface 120 is located, and the assembly efficiency of the dust-proof components 200 and the middle frame 100 can be improved. It is understood that the first step surface 154 may also be disposed opposite to the first surface 120, and the second step surface 155 may also be disposed opposite to the first surface 120, which is not limited in this application, and may be flexibly adjusted according to the use requirement in the actual production process.

The bending arrangement of the first channel 111 relative to the second channel 112 may be: the extending direction of the first passage 111 is arranged obliquely to the extending direction of the second passage 112. Wherein, an inclination angle of the extending direction of the first channel 111 and the extending direction of the second channel 112 may be more than 0 ° and less than 180 °. The two channels which are inclined relatively can be processed by a three-axis milling machine, and the manufacturing cost cannot be increased.

Specifically, the central axis of the first sub-channel 1111, the central axis of the second sub-channel 1112, and the central axis of the third sub-channel 1113 in the first channel 111 may all be disposed along a first preset direction x, the central axis of the second channel 112 may be disposed along a second preset direction y, and the second preset direction y may be disposed obliquely with respect to the first preset direction x. The central axis of the first sub-channel 1111, the central axis of the second sub-channel 1112, and the central axis of the third sub-channel 1113 are all arranged along the first preset direction x, and may be collinear with the central axis of the first sub-channel 1111, the central axis of the second sub-channel 1112, and the central axis of the third sub-channel 1113, or may be parallel to at least two of the central axis of the first sub-channel 1111, the central axis of the second sub-channel 1112, and the central axis of the third sub-channel 1113. The central axis of the first sub-channel 1111, the central axis of the second sub-channel 1112 and the central axis of the third sub-channel 1113 are all arranged along the first preset direction x, so that the first channel 111 can be conveniently machined and formed.

In addition, since the alignment, the parallelism, or the like cannot be realized in a strict sense due to factors such as manufacturing errors, the alignment, the parallelism, or the like can be referred to as the alignment or the parallelism within an error tolerance range. The allowable error range can be adjusted according to practical conditions, for example, the inclination angles of the two straight lines can be called as parallel between-10 ° and 10 °, which is not limited in the embodiments of the present application.

The second channel 112 may extend in a direction parallel to the first face 120, or may extend in a direction non-parallel to the first face 120. When the extending direction of the second channel 112 is parallel to the first surface 120, the processing and forming of the second channel 112 are facilitated. When the extending direction of the second channel 112 is not parallel to the first surface 120, the path length of the second channel 112 can be extended compared to the parallel direction, so as to achieve a better dust filtering effect.

Preferably, when the extending direction of the second channel 112 is not parallel to the first surface 120, the distance between the end of the second channel 112 far away from the first channel 111 and the first surface 120 may be smaller than the distance between the end of the second channel 112 close to the first channel 111 and the first surface 120. The distance between the end of the second channel 112 close to the first channel 111 and the first surface 120 is set to be larger, so that the end of the first channel 111 far from the first surface 120 is closer to the second surface 130, thereby prolonging the path length of the first channel 111 and improving the dust filtering effect of the first channel 111. In addition, the distance between the end of the second channel 112 far from the first channel 111 and the first surface 120 is set to be smaller, so that the port of the second channel 112 connected with the appearance surface 140 can be arranged in the center on the premise of ensuring that the length of the route of the first channel 111 is large enough, and the structure of the electronic device 1 is more attractive.

In an exemplary aspect, the at least two dust shields 200 may include a first dust shield 210 and a second dust shield 220, the first dust shield 210 may be mounted to the first step surface 154, and the second dust shield 220 may be mounted to the second step surface 155. The number of the dust-proof pieces 200 is set to two, so that the structure of the electronic device 1 can be simplified while the dust-proof effect is satisfied, and the assembly efficiency of the electronic device 1 is improved.

Referring to fig. 5, the second dust-proof member 220 may include a connection portion 221 and a dust-proof portion 222, the connection portion 221 may be attached to the second step surface 155 and connected to the second step surface 155, and the dust-proof portion 222 may be located in the sound guide channel 110 and connected to the connection portion 221. The connection portion 221 and the dust-proof portion 222 may be an integrated structure, so that an assembly process of the connection portion 221 and the dust-proof portion 222 is omitted.

The connecting portion 221 has a first end face 2211 facing the second step face 155, the dust-proof portion 222 has a second end face 2221 and a third end face 2222 opposite to the second end face 2221, and the second end face 2221 and the first end face 2211 may be located on the same side of the second dust-proof member 220. Second inner wall surface 160 forming second channel 112 may have a first edge line 161 connecting first inner wall surface 150, and first edge line 161 may be located on a side of second end surface 2221 away from third end surface 2222 with a gap from second end surface 2221. Therefore, when the dust passes through the corners of the first channel 111 and the second channel 112, the dust does not directly contact with the dust-proof part 222, and part of the dust contacts with the dust-proof part 222 only after the transmission direction needs to be changed, so that the deformation phenomenon of the dust-proof part 222 caused by the impact of the dust is reduced.

Preferably, the minimum spacing between second end surface 2221 and first edge line 161 in a direction perpendicular to second end surface 2221 may be greater than or equal to 0.2 mm; so as to ensure that the impact force of the dust reaching the dust-proof part 222 to the dust-proof part 222 is small, and further extend the service life of the second dust-proof member 220.

Referring to fig. 4 and 5, since the second step surface 155 is located between the third sub-passage 1113 and the second sub-passage 1112, and a side of the second sub-passage 1112 far from the third sub-passage 1113 is close to the second passage 112, the second step surface 155 is located between the first step surface 154 and the first edge line 161. In order to form a gap between the second end surface 2221 of the second dust-proof member 220 disposed on the second step surface 155 and the first edge line 161 of the second channel 112, the second end surface 2221 may be located on a side of the second step surface 155 close to the first step surface 154, and form a gap with the second step surface 155; and/or, the first edge line 161 is located on a side of the second step surface 155 away from the first step surface 154 with a gap from the second step surface 155.

The second end surface 2221 is located on the side of the second step surface 155 close to the first step surface 154 and has a gap with the second step surface 155; and/or, the first edge line 161 is located on the side of the second step surface 155 away from the first step surface 154 and has a gap with the second step surface 155 ", may include that the second end surface 2221 is located on the side of the second step surface 155 close to the first step surface 154 and has a gap with the second step surface 155, and the first edge line 161 is located on the side of the second step surface 155 away from the first step surface 154 and has a gap with the second step surface 155; or separately positioning the second end surface 2221 on the side of the second step surface 155 close to the first step surface 154 and having a gap with the second step surface 155; it may also include separately positioning the first edge line 161 on a side of the second step surface 155 away from the first step surface 154 with a gap from the second step surface 155. When the second end surface 2221 is located on the side of the second step surface 155 close to the first step surface 154 and has a gap with the second step surface 155, the second end surface 2221 and the first end surface 2211 may be regarded as forming a step, and this structural design can be directly implemented in the production and manufacturing of the second dust-proof portion 222, which is less difficult to design. When the first edge line 161 is located on the side of the second step surface 155 away from the first step surface 154 and has a gap with the second step surface 155, the processing of the sound guide channel 110 may be adjusted, for example, the design of the depth of the third sub-channel 1113 may be changed or the design of the inclination angle of the second channel 112 with respect to the first channel 111 may be changed, and the forming process is relatively simple.

The first dust prevention member 210 may be provided with a first mesh, and the second dust prevention member 220 may be provided with a second mesh, and the first mesh may have a smaller pore size than the second mesh. The aperture of the first mesh is set to be smaller than that of the second mesh, so that larger particles of dust are firstly filtered by the second mesh after the dust enters the sound guide channel 110, and then the smaller particles are filtered by the first mesh after the dust continues to be transmitted to the first mesh, and the filtering effect is better. Wherein, the aperture of first mesh can be about 0.03mm, and the aperture of second mesh can be about 0.12mm, can be according to the nimble adjustment of user demand in the actual production process. It is understood that the aperture of the first mesh can be equal to the aperture of the second mesh, and the like, and the embodiment of the present application is not limited thereto.

In an exemplary scheme, the circuit board 40 may be connected to the first surface 120 of the middle frame 100, the circuit board 40 may be provided with a sound guide hole 41, and the microphone 20 may be connected to a side of the circuit board 40 away from the first surface 120 and corresponding to the sound guide hole 41 on the circuit board 40. Since the board area of the circuit board 40 is larger, the microphone 20 is disposed on the circuit board 40 after the circuit board 40 is connected to the first surface 120, and the disposition of the circuit board 40 and the microphone 20 is more stable than disposing the circuit board 40 on the side of the microphone 20 away from the first surface 120 after the microphone 20 is disposed on the first surface 120.

In an exemplary scheme, referring to fig. 6 and 7, the first surface 120 of the middle frame 100 may be provided with a groove 121, the groove 121 has a bottom 1211 and a side wall surface 1212 connected to the bottom 1211, the sound guiding channel 110 may penetrate through the bottom 1211 and the exterior surface 140, the circuit board 40 may be located in the groove 121 and connected to the bottom 1211, at this time, the electronic device 1 may further include an antenna 60 and an elastic sheet 50, since the side wall surface 1212 of the groove 121 and the sound guiding channel 110 are independent from each other, the antenna 60 may be directly formed on the side wall surface 1212, and the elastic sheet 50 is disposed in the groove 121 and electrically connected to both the antenna 60 and the circuit board 40, so as to implement an antenna function.
