[0017] The present application will be further described in detail below in conjunction with the accompanying drawings and examples. It is particularly noted that the following examples are only intended to illustrate the present application and are not intended to limit the scope of the present application. Similarly, the following examples are only some examples of the present application and not all examples. All other examples obtained by those of ordinary skill in the art without creative work are intended to fall within the scope of protection of this application.

[0018] Reference to an "embodiment" in this application means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive of one another. As will be apparent to those of ordinary skill in the art, embodiments described herein can be combined with other embodiments.

[0019] Please refer to Figures 1 to 2 , Figure 1 is a structural schematic diagram of an earphone 10 provided by an embodiment of the application, Figure 2 is Figure 1 an exploded structural schematic diagram of the earphone 10.

[0020] The earphone 10 provided by the embodiment of the application can be a wireless earphone, a wired earphone, or a smart sound box, etc. In the following, only the earphone 10 is taken as a wireless earphone for example. As shown in Figures 1 to 2 , the earphone 10 can include a shell assembly 100, a sound emitting assembly 200, and a sound pickup assembly 300. The shell assembly 100 can accommodate various structural components required by the earphone 10, and is provided with an outer shape adapted to the ear of a user for the user to wear. The sound emitting assembly 200 is arranged in the shell assembly 100, and can convert an electrical signal into an acoustic signal to realize the sound playing function of the earphone 10. The sound pickup assembly 300 is also arranged in the shell assembly 100, and can convert an acoustic signal into an electrical signal to realize the acquisition of ambient sound by the earphone 10. In the embodiment, the sound pickup assembly 300 has the advantage of strong wind noise resistance, which is conducive to the use of the earphone 10 in a windy environment.

[0021] The shell assembly 100 can accommodate various structural components required by the earphone 10, and is provided with an outer shape adapted to the ear of a user for the user to wear. As shown in Figures 1 to 2 , the shell assembly 100 can include a front shell 110, a middle shell 120, and a rear shell 130. The front shell 110 can be arranged on one side of the middle shell 120 and cooperatively surround the middle shell 120 to form a first accommodating space 101, and the front shell 110 is further provided with a sound outlet hole 111 communicating the inside and outside of the first accommodating space 101. For example, the part of the front shell 110 away from the middle shell 120 can be arranged in a ring shape to surround the sound outlet hole 111. Meanwhile, the rear shell 130 can be arranged on the other side of the middle shell 120 opposite to the front shell 110 and cooperatively surround the middle shell 120 to form a second accommodating space 102, and the middle shell 120 is further provided with a sound pickup hole 121 communicating the inside and outside of the second accommodating space 102. For example, the side of the middle shell 120 away from the rear shell 130 can be provided with the sound pickup hole 121.

[0022] Furthermore, the first storage space 101 can be used to install the sound-emitting component 200, and can be divided into a front sound cavity and a rear sound cavity by the sound-emitting component 200. The sound outlet 111 can be connected to the front sound cavity, and the sound wave signal emitted by the sound-emitting component 200 in the front sound cavity can be transmitted to the outside of the first storage space 101 through the sound outlet 111, thereby realizing the sound playback function of the earphone 10. The second storage space 102 can be used to install the sound pickup component 300, and the sound pickup hole 121 can transmit the external sound wave signal to the second storage space 102 for reception by the sound pickup component 300, thereby realizing the earphone 10 to obtain the ambient sound.

[0023] In some embodiments, the sound pickup hole 121 is not limited to being located on the middle shell 120. For example, the sound pickup hole 121 can also be located on the front shell 110 or the rear shell 130, or at the junction of the middle shell 120 and the rear shell 130 (where the middle shell 120 and the rear shell 130 are formed together). In other words, the location of the sound pickup hole 121 on the housing assembly 100 can be selected based on design requirements. It is sufficient that the housing assembly 100 is provided with the sound pickup hole 121, and that the sound pickup hole 121 can transmit external sound wave signals to the second accommodation space 102 for reception by the sound pickup assembly 300. This embodiment does not limit this.

[0024] Furthermore, in addition to housing the sound pickup assembly 300, the second storage space 102 can also accommodate other components required for the earphone 10, such as a battery, motherboard, antenna, and touchpad. Furthermore, the first storage space 101 can also communicate with the second storage space 102, allowing the sound-generating assembly 200 to be electrically connected to the motherboard within the second storage space 102 and operate under the motherboard's control. For example, portions of the middle shell 120 located in the first storage space 101 and the second storage space 102 can be penetrated to achieve communication between the first storage space 101 and the second storage space 102.

[0025] It is understood that the earphones 10 can be not only the stem-type earphones shown in the illustration, but also be bean-type earphones or other types of wireless earphones. The specific shape and composition of the housing assembly 100 can also be adjusted according to the type of earphones 10 and is not limited to the solution shown in the above embodiment. That is, the housing assembly 100 shown in the above embodiment is only an example, and the specific shape and composition of the housing assembly 100 are not limited to this. This embodiment will not be described in detail here.

[0026] The sound-emitting component 200 can be arranged in the shell component 100 and can convert electrical signals into sound wave signals to realize the sound playback function of the earphone 10. Specifically, the sound-emitting component 200 can be arranged in the first storage space 101 and can be electrically connected to the mainboard in the second storage space 102 through electrical connectors such as a flexible circuit board, and the sound-emitting component 200 can convert the electrical signals transmitted by the mainboard into sound wave signals and emit them. At the same time, the sound-emitting component 200 can separate the first storage space 101 into front and rear sound cavities, and the sound wave signals emitted by the sound-emitting component 200 in the front sound cavity can also be transmitted to the outside of the first storage space 101 through the sound outlet 111 for the wearer to listen to. In addition, the sound-emitting component 200 may include: a sound-emitting device for converting electrical signals into sound wave signals, and the sound-emitting device can be any one or more combinations of speakers such as dynamic coil type, moving iron type, ring iron type and planar diaphragm type.

[0027] All directional indications in the embodiments of the present application (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly. In addition, the terms "including" and "provided with" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices.

[0028] See also Figures 3 to 5 , Figure 3 yes Figure 2 Schematic diagram of the connection structure between the middle shell 120 and the pickup assembly 300, Figure 4 yes Figure 3 A schematic diagram of the cross-sectional structure of the middle shell 120 and the pickup assembly 300 along the section line V-V, Figure 5 yes Figure 4 Schematic diagram of the structure of the middle guide plate 311.

[0029] The sound pickup assembly 300 is disposed in the housing assembly 100 and can convert the sound wave signal into an electrical signal so that the earphone 10 can obtain the ambient sound. Figures 3 and 4As shown, the pickup assembly 300 can include a flow guide support 310 and a pickup microphone 320. The flow guide support 310 and the pickup microphone 320 are both arranged in the second accommodating space 102, and the flow guide support 310 is further connected with the pickup microphone 320 and communicates the pickup hole 121 with the pickup microphone 320. Meanwhile, the flow guide support 310 can further transmit the sound wave signal transmitted by the pickup hole 121 to the pickup microphone 320 for receiving by the pickup microphone 320, so as to realize the acquisition of the ambient sound by the earphone 10. In this embodiment, the flow guide support 310 can slow down the flow rate of the airflow flowing from the pickup hole 121 to the pickup microphone 320, so as to reduce the wind noise generated by the pickup microphone 320, thereby improving the wind noise resistance of the pickup assembly 300.

[0030] Specifically, when the wearer is in a windy environment, such as an outdoor windy scene or a fast moving scene (running or cycling, etc.), the flow rate of the airflow entering the pickup hole 121 is often fast, and the fast flow rate of the airflow will cause the pickup microphone 320 to generate greater wind noise, thereby affecting the use of the pickup microphone 320 in this scene. Based on this, in order to slow down the flow rate of the airflow flowing to the pickup microphone 320, the flow guide support 310 can be provided with a main flow channel 301 and a branch flow channel 302. As shown in the figure, Figures 4 and 5 The main flow channel 301 can communicate the pickup hole 121 with the pickup microphone 320, and the main flow channel 301 can transmit the airflow entering from the pickup hole 121 to the pickup microphone 320. The branch flow channel 302 can communicate with the main flow channel 301, and the branch flow channel 302 can branch the airflow flowing from the main flow channel 301 to the pickup microphone 320, and guide the branched airflow back to the main flow channel 301 to collide with the airflow flowing to the pickup microphone 320 in the main flow channel 301, thereby forming a vortex to slow down the flow rate of the airflow flowing to the pickup microphone 320 in the main flow channel 301. In this way, the flow guide support 310 can slow down the flow rate of the airflow flowing from the pickup hole 121 to the pickup microphone 320, so as to achieve the purpose of reducing the wind noise generated by the pickup microphone 320.

[0031] Further, in order to form the main flow channel 301 and the branch flow channel 302 on the flow guide support 310, the flow guide support 310 can include a flow guide plate 311 and a sealing cover 312. As shown in the figure, Figures 4 and 5 The flow guide plate 311 can be arranged on one side of the middle shell 120 where the pickup hole 121 is opened, and the sealing cover 312 can be arranged on the side of the flow guide plate 311 away from the pickup hole 121, and can be arranged together with the flow guide plate 311 to form the main flow channel 301 and the branch flow channel 302. For example, the side of the flow guide plate 311 where the sealing cover 312 is arranged can be provided with a groove for forming the main flow channel 301 and the branch flow channel 302, and the sealing cover 312 can be arranged on the groove of the flow guide plate 311 to form the main flow channel 301 and the branch flow channel 302 together with the groove and the flow guide plate 311.

[0032] In some embodiments, in addition to the groove formed on the deflector 311, the deflector 311 and the sealing cover 312 can also be provided with grooves for forming the main flow channel 301 and the branch flow channel 302, and when the sealing cover 312 is covered on the deflector 311, the grooves of the deflector 311 can be aligned with the grooves of the sealing cover 312 to jointly form the main flow channel 301 and the branch flow channel 302. At the same time, in order to facilitate the alignment of the deflector 311 and the sealing cover 312, the deflector 311 and the sealing cover 312 can also be respectively provided with cooperating positioning structures (such as positioning holes and positioning columns) to realize the positioning assembly of the deflector 311 and the sealing cover 312.

[0033] Further, in order to realize the communication of the main flow channel 301 and the pickup hole 121, the deflector support 310 is further provided with a pickup opening 303 for communicating the external atmosphere and the main flow channel 301. As shown in Figure 4 the deflector 311 is provided with a first through hole 313 for communicating the main flow channel 301 on the side opposite to the pickup hole 121, that is, the side of the deflector 311 away from the sealing cover 312. The first through hole 313 can form the pickup opening 303 on the side of the deflector 311 away from the sealing cover 312, and the first through hole 313 can be coaxially arranged with the pickup hole 121 and provided with the same aperture as the pickup hole 121, so that the pickup opening 303 can be aligned with the pickup hole 121 to realize the communication of the pickup hole 121 and the main flow channel 301.

[0034] In some embodiments, the aperture of the first through hole 313 can also be different from the aperture of the pickup hole 121. That is, the aperture of the first through hole 313 can be larger or smaller than the aperture of the pickup hole 121, so that the pickup opening 303 can be designed to be larger or smaller for alignment with the pickup hole 121. At the same time, in some embodiments, the position of the first through hole 313 can also be adjusted according to the position of the pickup hole 121, and is not limited to being formed on the side of the deflector 311 away from the sealing cover 312. In addition, in some embodiments, the hole wall of the first through hole 313 can also be part of the main flow channel 301, and is not limited to being a structure independent of the main flow channel 301.

[0035] In some embodiments, the side of the deflector 311 away from the sealing cover 312 can also be provided with a sealing ring arranged around the pickup opening 303, and the sealing ring can abut against the deflector 311 and the middle shell 120, respectively, to form a sealed space between the deflector 311 and the sealing cover 312, thereby improving the sealing performance of the main flow channel 301 and the pickup hole 121 at the pickup opening 303. At the same time, the middle shell 120 can also be provided with a dustproof screen and a waterproof and breathable film for covering the pickup hole 121, so as to enhance the waterproof and dustproof performance of the earphone 10 without affecting the breathability of the pickup hole 121.

[0036] Furthermore, in order to achieve the connection between the main channel 301 and the pickup 320, the guide bracket 310 may also be provided with a sound outlet 304 connected to the main channel 301. Figure 4 As shown, a second through hole 314 communicating with the main channel 301 can be formed on the side of the sealing cover 312 facing away from the deflector plate 311. The second through hole 314 can form a sound outlet 304 on the side of the sealing cover 312 facing away from the deflector plate 311. A microphone 320 can be disposed on the side of the sealing cover 312 facing away from the deflector plate 311, covering the sound outlet 304 formed by the second through hole 314, thereby establishing communication between the microphone 320 and the main channel 301. In this embodiment, the microphone 320 can be a microphone, and the diaphragm of the microphone 320 can be disposed facing the sound outlet 304, so that the microphone 320 can receive sound wave signals transmitted from the sound outlet 304.

[0037] In some embodiments, a sealing ring may be provided on the side of the sealing cover 312 facing away from the deflector 311, surrounding the sound outlet 304. The sealing ring may abut against the sealing cover 312 and the pickup 320, respectively, to form a sealed space between the sealing cover 312 and the pickup 320, thereby improving the sealing between the main channel 301 and the pickup 320 at the sound outlet 304. Furthermore, in some embodiments, the wall of the second through hole 314 may be part of the main channel 301, rather than being a separate structure from the main channel 301.

[0038] It should be understood that the aforementioned placement of the sound pickup port 303 and the sound outlet 304 is merely illustrative. When the positions of the sound pickup hole 121 and the sound pickup 320 change, the placement of the sound pickup port 303 and the sound outlet 304 will also change accordingly, and are not limited to the solutions shown in the above embodiment. For example, when the sound pickup hole 121 is located on the rear housing 130, the sealing cover 312 can be provided with the aforementioned sound pickup port 303 to communicate with the sound pickup hole 121. Alternatively, when the sound pickup 320 is located on one side of the deflector 311, the deflector 311 can be provided with the aforementioned sound outlet 304 to communicate with the sound pickup 320.

[0039] Please combine Figure 5 See Figures 6 and 7 , Figure 6 yes Figure 5 Schematic diagram of the flow direction of the middle airflow in the guide plate 311 toward the sound outlet 304, Figure 7 yes Figure 5 Schematic diagram of the flow direction of the middle airflow in the guide plate 311 toward the sound pickup port 303 .

[0040] like Figures 5 to 7As shown, the main channel 301 can guide the airflow entering from the sound pickup port 303 to the sound outlet 304, while the branch channel 302 can be connected to the main channel 301 and can divert the airflow flowing from the main channel 301 to the sound pickup 320. The branch channel 302 can also guide the diverted airflow back to the main channel 301, so that it collides with the airflow flowing from the main channel 301 to the sound outlet 304 (the sound pickup 320), thereby forming a vortex and slowing down the flow rate of the airflow flowing from the main channel 301 to the sound outlet 304. At the same time, the branch channel 302 can also divert the airflow flowing from the main channel 301 to the sound pickup port 303 and guide the diverted airflow back to the main channel 301 to converge with the airflow flowing from the main channel 301 to the sound pickup port 303, so that the converged airflow flows out of the sound pickup port 303. In addition, the flow rate of the airflow from the sound pickup port 303 to the sound outlet 304 may be lower than the flow rate of the airflow from the sound outlet 304 to the sound pickup port 303. Figure 6 and Figure 7 The solid arrows shown in the figure may be the main flow path and direction of the airflow in the guide plate 311, and the solid coils with arrows may be vortices formed by the collision of the airflows.

[0041] Furthermore, the branch channel 302 may be provided with a first channel opening 3021 and a second channel opening 3022 communicating with the main channel 301. When air flows from the main channel 301 toward the sound outlet 304, part of the airflow may flow from the first channel opening 3021 into the branch channel 302, and after being guided by the branch channel 302, flow into the main channel 301 from the second channel opening 3022, thereby colliding with the airflow flowing from the main channel 301 toward the sound outlet 304, thereby forming a vortex that slows down the flow rate of the airflow from the main channel 301 toward the sound outlet 304. When the air flow flows from the main channel 301 to the sound outlet 304, part of the air flow can flow into the branch channel 302 from the second channel opening 3022, and after being guided by the branch channel 302, flow into the main channel 301 from the first channel opening 3021 to converge with the air flow flowing from the main channel 301 to the sound pickup port 303, so that the converged air flow flows out from the sound pickup port 303.

[0042] In some embodiments, the direction of the airflow flowing from the second flow channel opening 3022 into the main channel 301 can intersect with the direction of the airflow in the main channel 301 and form an angle greater than or equal to 90°, such as 90°, 120°, or 150°, so that the direction of the airflow flowing from the second flow channel opening 3022 into the main channel 301 is approximately opposite to the direction of the airflow in the main channel 301, thereby colliding and slowing down the flow rate of the airflow. Similarly, the direction of the airflow flowing from the first flow channel opening 3021 into the main channel 301 can intersect with the direction of the airflow in the main channel 301 and form an angle less than or equal to 60°, such as 60°, 45°, or 30°, so that the direction of the airflow flowing from the first flow channel opening 3021 into the main channel 301 is approximately the same as the direction of the airflow in the main channel 301, thereby converging without affecting the flow rate or with little effect on the flow rate. It can be understood that the angle value of the aforementioned angle is only for illustrative purposes, and the specific angle value of the angle can also be adjusted according to design requirements, which is not limited in this embodiment.

[0043] Furthermore, in order to better divert the airflow from the main channel 301 to the sound outlet 304, the branch channel 302 is connected to the channel wall of the main channel 301 at the first channel opening 3021 to form an angular angle 3023 ( Figure 5 ), the corners 3023 are used to improve the efficiency of airflow diversion at the first flow channel opening 3021. Furthermore, to enhance the convergence of airflow at the first flow channel opening 3021, the corners 3023 can be designed to be relatively small, such as 15°, 20°, or 30°, so that the direction of airflow out of the first flow channel opening 3021 is similar to the direction of airflow flowing from the main flow channel 301 to the sound pickup port 303.

[0044] In some embodiments, the connection between the branch channel 302 and the main channel 301 at the first channel opening 3021 is not limited to forming an angle, as long as the airflow can be diverted at the first channel opening 3021. This embodiment does not limit this.

[0045] Furthermore, in order to allow the airflow flowing from the second flow channel opening 3022 into the main channel 301 to collide with the airflow flowing from the main channel 301 toward the sound outlet 304, the branch channel 302 is provided with a rounded flow channel wall arranged near the second flow channel opening 3022. The rounded flow channel wall can change the flow direction of the airflow in the branch channel 302, so that the flow direction of the airflow flowing from the second flow channel opening 3022 into the main channel 301 can be approximately opposite to the flow direction of the airflow flowing from the main channel 301 toward the sound outlet 304, thereby achieving the collision of the airflow flowing from the second flow channel opening 3022 into the main channel 301 and the airflow flowing from the main channel 301 toward the sound outlet 304, thereby forming a vortex to slow down the flow rate of the airflow flowing from the main channel 301 toward the sound outlet 304. At the same time, the rounded channel wall reduces the airflow entering the branch channel 302 from the second channel opening 3022 when the airflow passes through the second channel opening, so as to avoid affecting the efficiency of the airflow flowing in the main channel 301 to the sound pickup port 303, which is conducive to quickly draining the liquid in the guide bracket 310 after water enters the guide bracket 310.

[0046] In some embodiments, the flow channel wall of the branch channel 302 arranged near the second flow channel opening 3022 may not be limited to a rounded shape. It only needs that the flow channel wall of the branch channel 302 arranged near the second flow channel opening 3022 can guide the airflow to collide with the airflow in the main channel 301 to form a vortex to slow down the flow rate of the airflow in the main channel 301 to the sound outlet 304. This embodiment does not limit this.

[0047] Furthermore, in order to better slow down the flow rate of the airflow flowing from the main channel 301 to the sound outlet 304, the number of branch channels 302 can be multiple, and the multiple branch channels 302 can be distributed in different areas of the main channel 301 along the flow direction of the airflow in the main channel 301. Among them, the multiple branch channels 302 divert and guide the airflow flowing from the main channel 301 to the sound outlet 304, so as to form multiple vortices in the main channel 301 due to the collision of the airflow, thereby improving the airflow slowing effect of the guide bracket 310, and achieving the purpose of reducing the wind noise of the sound outlet 304. In the description of this application, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0048] For example, the number of the branch channels 302 may be three, and the three branch channels 302 may be a first branch channel 302a, a second branch channel 302b, and a third branch channel 302c. Figure 5As shown, the first branch channel 302a and the second branch channel 302b can be located on the same side of the main channel 301, and the first branch channel 302a can be arranged close to the sound pickup port 303, while the second branch channel 302b can be arranged close to the sound outlet 304. At the same time, the second channel opening 3022 of the first branch channel 302a can also overlap with the first channel opening 3021 of the second branch channel 302b. The third branch channel 302c can be located on the other opposite side of the main channel 301 and be arranged opposite to the first branch channel 302a and the second branch channel 302b. With such an arrangement, not only can the three branch channels 302 be used to slow down the flow rate of the airflow flowing from the main channel 301 to the sound outlet 304, but the layout of the three branch channels 302 on opposite sides of the main channel 301 can also reduce the space occupied by the guide bracket 310.

[0049] It is understandable that the number of branch channels 302 can also be four, five, six or more, and the multiple branch channels 302 can be distributed in sequence on the same side or opposite sides of the main channel 301 along the flow direction of the airflow in the main channel 301, and this embodiment does not limit this. The terms "first", "second" and "third" in this application are used for descriptive purposes only and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first", "second" and "third" can explicitly or implicitly include at least one of such features.

[0050] See also Figures 8 to 10 , Figure 8 yes Figure 4 Another structural diagram of the middle guide plate 311, Figure 9 yes Figure 5 Schematic diagram of the flow direction of the middle airflow in the guide plate 311 toward the sound outlet 304, Figure 10 yes Figure 5 Schematic diagram of the flow direction of the middle airflow in the guide plate 311 toward the sound pickup port 303 .

[0051] Furthermore, the layout of the main channel 301 and the plurality of branch channels 302 is also not limited to the solution shown in the above embodiment. Figures 8 to 10 As shown, the flow guide bracket 310 may further be provided with a diverter 315 in the main channel 301, and the diverter 315 may separate the main channel 301 into a first main channel 3011 and a second main channel 3012. At the same time, the number of branch channels 302 may also be two, and the two branch channels 302 are respectively a first branch channel 302a and a second branch channel 302b, and the first main channel 3011 may be connected to the first branch channel 302a, and the second main channel 3012 may be connected to the second branch channel 302b. Figure 9 and Figure 10The solid arrows shown in the figure may be the main flow path and direction of the airflow in the guide plate 311, and the solid coils with arrows may be vortices formed by the collision of the airflows.

[0052] Furthermore, the first branch channel 302a can divert the airflow flowing from the first main channel 3011 toward the sound outlet 304 and guide the diverted airflow back into the first main channel 3011, so that it collides with the airflow flowing from the first main channel 3011 toward the sound outlet 304, thereby forming a vortex and slowing down the flow rate of the airflow flowing from the first main channel 3011 toward the sound outlet 304. At the same time, the second branch channel 302b can divert the airflow flowing from the second main channel 3012 toward the sound outlet 304 and guide the diverted airflow back into the second main channel 3012, so that it collides with the airflow flowing from the second main channel 3012 toward the sound outlet 304, thereby forming a vortex and slowing down the flow rate of the airflow flowing from the second main channel 3012 toward the sound outlet 304.

[0053] Furthermore, the diverter 315 may only separate a portion of the main channel 301, while the portion of the main channel 301 not separated by the diverter 315 may be a shared area between the first main channel 3011 and the second main channel 3012. The first main channel 3011 and the second main channel 3012 may be symmetrically arranged on opposite sides of the diverter 315, while the first branch channel 302a may be located on a side of the first main channel 3011 facing away from the second main channel 3012, and the second branch channel 302b may be located on a side of the second main channel 3012 facing away from the first main channel 3011. Furthermore, the first branch channel 302a and the second branch channel 302b may also be symmetrically arranged. It can be understood that the above-mentioned arrangement of the main channel 301 and the branch channel 302 is only for illustrative purposes. There can be many other arrangements of the main channel 301 and the branch channel 302. It is only necessary for the main channel 301 and the branch channel 302 to cooperate with each other to slow down the flow rate of the airflow to the sound outlet 304. This embodiment will not be described in detail here.

[0054] The sound pickup assembly 300 provided herein is provided with a main channel 301 connected to the sound pickup 320, and a branch channel 302 connected to the main channel 301. The branch channel 302 can also divert airflow from the main channel 301 to the sound pickup 320 and guide the diverted airflow back to the main channel 301, where it collides with the airflow flowing from the main channel 301 to the sound pickup 320, thereby forming a vortex that slows the flow of air from the main channel 301 to the sound pickup 320. With this arrangement, the sound pickup assembly 300 can use the flow guide bracket 310 to slow the flow of air toward the sound pickup 320, thereby reducing wind noise generated by the high-speed airflow at the sound pickup 320.
