Description

Technical Field

[0001] The present application relates to the technical field of terminal devices, and in particular to a shell assembly and a preparation method thereof, glasses, a wearable device, and an electronic device. Background Art

[0002] With the continuous advancement of science and technology, more and more electronic equipment products are pouring into people's lives. For example, wearable electronic devices are favored by the majority of users due to their wearable convenience, intelligence and versatility. Taking smart glasses as an example, smart glasses can realize the interaction of visual, auditory and other information, and meet users' needs for calls, listening to music, navigation, etc., and have gradually become one of the more common wearable electronic devices in smart life.

[0003] Taking smart glasses as an example, the smart glasses may include temples, through which the glasses can be worn on the user's head, such as the temples can be placed on the ears. The temples may include a shell and a microphone, the shell may have a receiving cavity, and a sound pickup hole may be opened on the shell. The sound hole of the microphone is connected to the sound pickup hole, and the sound emitted by the user can enter the microphone through the sound pickup hole and then be converted into an electronic signal, thereby realizing voice interaction functions such as calls of wearable electronic devices.

[0004] When glasses and other devices are used in windy scenarios such as outdoors, wind blowing onto the microphone will generate wind noise signals, affecting the normal use of the device and reducing the user experience. Summary of the invention

[0005] The embodiments of the present application provide a shell assembly and a preparation method, glasses, a wearable device, and an electronic device. The shell assembly has a good wind noise reduction effect, ensures the normal use of glasses and other devices in windy scenes, and improves the user experience.

[0006] A first aspect of an embodiment of the present application provides a shell assembly, including an outer shell, a sound pickup port being provided on the outer shell, a accommodating cavity and a first sound pickup channel being provided inside the outer shell, the accommodating cavity being used to accommodate a microphone, the sound pickup port being connected to the first sound pickup channel, the first sound pickup channel being connected to the accommodating cavity, so that the first sound pickup port can be connected to the sound hole of the microphone in the accommodating cavity through the first sound pickup channel, and the setting of the first sound pickup channel can realize the diversion and attenuation of wind noise signals, thereby achieving the effect of reducing wind noise.

[0007] The housing assembly further includes a fluff structure, which is arranged on at least one of the inner surface of the sound pickup port, the inner surface of the first sound pickup channel, and a portion of the outer surface of the housing adjacent to the sound pickup port. The fluff structure can be formed by arranging a plurality of flexible fluffs, the fluffs are in a fiber state, and the flexible fluffs can swing and deform.

[0008] When the wind flows through the shell of the shell assembly, it can enter the microphone from the sound pickup port and the first sound pickup channel to generate a wind noise signal. By making the fluff structure located on at least one of the inner surface of the sound pickup port, the inner surface of the first sound pickup channel and the outer surface of the part of the shell adjacent to the sound pickup port, that is, a fluff structure is arranged on the path of the wind flow to the microphone. The wind flows through the fluff structure, and the fiber state of the fluff structure can break up the large vortex generated by the wind flow and form a small vortex with less energy. The small vortex is more easily dissipated, thereby reducing the impact of the vortex. The fluff of the fluff structure can swing and deform under the action of the wind flow, and enhance the energy dissipation of the vortex during the swinging process. Moreover, the fluff structure is composed of a plurality of fluffs arranged, with a large density, which increases the friction energy consumption between the air and the air, and can also play a role in dissipating the energy of the wind vortex. Therefore, the fluff structure can achieve a good wind noise reduction effect, reduce the wind noise signal of the microphone, ensure the normal use of electronic devices such as glasses in windy scenes, and enhance the use experience. In addition, the fluff structure can also refract and reflect the wind sound energy, and can also reduce the sound wave energy, further reducing the wind noise.

[0009] In a possible implementation, the housing includes a shell member and an assembly member, the shell member has a mounting wall, and the shell member has a receiving cavity. The assembly member is covered on the mounting wall, and a gap is provided between the inner surface of the assembly member and the mounting wall to form a first sound pickup channel, and at least one of the assembly member and the shell member is provided with an opening to form a sound pickup port. In other words, the first sound pickup channel and the sound pickup port are formed by the assembly design of the assembly member and the shell member, which is conducive to realizing the structural design of the first sound pickup channel and the sound pickup port, and reducing the difficulty of structural design and production of the temple.

[0010] In a possible implementation, the fluff structure is disposed on the assembly part. The structural design of the assembly part is relatively simple, and the fluff structure is disposed on the assembly part, which can facilitate the formation and assembly of the fluff structure, thereby reducing the difficulty of forming or assembling the fluff structure on the shell.

[0011] In a possible implementation, the inner surface of the assembly part is surrounded by a groove structure, and a part of the area of ​​the mounting wall is raised to form a raised structure that matches the groove structure, and there is a gap between the groove structure and the raised structure to form a first sound pickup channel. The raised structure is formed by a curved protrusion on the mounting wall of the shell part, and the groove structure is surrounded by a curved depression on the inner surface of the assembly part. Therefore, the first sound pickup channel located between the raised structure and the groove structure is a bent structure, which is a bent and extended curved channel, rather than a horizontally extended flat channel. It can extend the length of the first sound pickup channel and the path length of the wind vortex from the sound pickup port to the accommodating cavity. It can well weaken the transmission of the pulsating pressure formed by the wind vortex in the first sound pickup channel, thereby reducing the impact of wind noise on the microphone, achieving the effect of attenuating wind noise, further reducing the wind noise signal picked up by the microphone, and more conducive to improving the wind noise reduction effect.

[0012] In a possible implementation, the assembly includes a first side wall, a second side wall and a third side wall that are connected, the second side wall is located between the first side wall and the third side wall, and the first side wall and the third side wall are opposite, and the inner surfaces of the first side wall, the second side wall and the third side wall form a groove structure. The structure is simple and is convenient for realizing the groove structure. Under the condition of forming a bent first sound pickup channel, it is helpful to reduce the structural design and production difficulty of the assembly.

[0013] The sound pickup opening includes a first sound pickup opening and a second sound pickup opening. An opening is formed at one end of the first side wall facing away from the second side wall to form the first sound pickup opening, and an opening is formed at one end of the third side wall facing away from the second side wall to form the second sound pickup opening. The sound pickup opening is provided on the assembly part, which is conducive to the molding of the sound pickup opening and is conducive to reducing the difficulty of the structural design of the shell part, making it easy to realize.

[0014] Moreover, the first sound pickup port and the second sound pickup port are arranged relative to each other, and the first sound pickup port and the second sound pickup port are respectively connected to the first sound pickup channel. The connected first sound pickup port and the second sound pickup port can form a pressure relief design to reduce the impact of wind noise on the microphone. The wind vortex can enter through the first sound pickup port, part of it can enter the accommodating cavity through the second sound pickup channel, and part of it can flow out through the second sound pickup port, thereby achieving the effect of pressure relief, further reducing the wind noise signal picked up by the microphone, and further improving the wind noise reduction effect. Correspondingly, part of the wind vortex that enters through the second sound pickup port can flow out through the first sound pickup port, further improving the wind noise reduction effect.

[0015] In one possible implementation, at least one of the inner surfaces of the first sound pickup port and the second sound pickup port, the inner surface of the assembly, and the outer surface of the assembly is completely covered with a fluff structure, which facilitates the assembly or forming of the fluff structure on the outer shell while ensuring a good wind noise reduction effect, and helps to reduce the noise reduction cost.

[0016] In one possible implementation, the length of the fluff structure located on the inner surface of the sound pickup port is greater than or equal to the width of the sound pickup port, that is, the fluff of the fluff structure located on the sound pickup port has an interference fit with the sound pickup port, and the fluff fills the entire sound pickup port, which is beneficial to improving the wind noise reduction effect at the sound pickup port, thereby improving the wind noise reduction effect of the entire device and improving the user experience.

[0019] In a possible implementation, a second adhesive layer is further included. The second adhesive layer is located between the side of the substrate facing away from the fluff and the outer shell.

[0086] The terms used in the implementation section of this application are only used to explain the specific embodiments of this application and are not intended to limit this application.

[0087] An embodiment of the present application provides a shell assembly that can be used in an electronic device. The electronic device may include a shell assembly and a microphone. The microphone can be fixed in the shell assembly to meet the sound pickup requirements of the electronic device, so that the electronic device can realize functions such as language control and calls through the microphone.

[0088] The electronic device may be any device that has a sound pickup requirement, for example, the electronic device may be a mobile phone, a tablet computer, a laptop computer, or other conveniently portable device.

[0089] Alternatively, the electronic device may also be a wearable electronic device such as headphones, smart watches, smart glasses, etc.

[0090] Taking smart glasses as an example, the glasses may include a frame and temples, the temples may be the shell components mentioned above, and the shell components are fixed to the frame. A shell component may be fixed on each side of the frame, the frame may be used to install lenses, the lenses may be ordinary lenses, and the user may observe the scene outside the glasses through the lenses.

[0091] The glasses can be worn on the user's head through the shell assembly (temples), for example, the shell assembly can be mounted on the ears of the user's head, and the ears provide stable support for the shell assembly to achieve wearing. Among them, the frame can be mounted on the bridge of the nose of the user's head to further ensure that the glasses are stably worn on the head.

[0092] The shell assembly can be rotated with the frame. For example, the two shell assemblies can be rotated with the frame through hinge structures, so that the shell assembly can be rotated and folded relative to the frame (for example, the angle between the shell assembly and the frame can be 0°), which is convenient for storing the glasses. When it is necessary to wear the glasses, the shell assembly can be rotated relative to the frame and unfolded (for example, the angle between the shell assembly and the frame can be 90°). The two shell assemblies can be clamped on the user's head, and the two shell assemblies can be mounted on the ears, and the frame can be mounted on the bridge of the nose.

[0093] Of course, in some other examples, the shell assembly and the frame may not be limited to the form of rotational cooperation. For example, the shell assembly and the frame may be fixedly assembled and the two cannot rotate relative to each other.

[0094] Alternatively, the electronic device may also be a wearable device capable of realizing interaction, for example, the wearable device may also be an electronic device of augmented reality (AR), virtual reality (VR), and mixed reality (MR), for example, VR glasses, AR glasses, MR glasses, etc. Of course, in some other examples, the wearable device may not be limited to the form of glasses, and may be other types of wearable devices, such as other wearable devices adapted to the head.

[0095] The wearable device may include a wearable device and a shell assembly. The wearable device may be used to achieve interaction with the user. For example, taking the wearable device as AR glasses, the wearable device may be an AR device that may superimpose virtual data onto the real-time image captured by the device and display it, thereby achieving interaction with the user.

[0096] Accordingly, a shell assembly can be fixed on each side of the wearable device, and the wearable device can be worn on the user's head through the shell assembly. The shell assembly and the wearable device can be rotatably matched, or the two can be fixedly assembled and cannot rotate relative to each other.

[0097] In the embodiment of the present application, the shell assembly is described by taking the electronic device as glasses as an example.

[0098] Figure 1 A schematic structural diagram of a housing assembly provided in an embodiment of the present application.

[0099] See also Figure 1 As shown, the housing assembly 100 may include a shell 10 , which may serve as a main load-bearing structural component of a device such as glasses, and may provide an assembly space for various structural components of the device.

[0100] Exemplarily, the housing 10 may include a connecting end 102 and a wearing end 101. The connecting end 102 can be used to be fixed to the frame, and the wearing end 101 can be used to be mounted on the user's ear. For example, one side of the wearing end 101 can be recessed to form an arc structure to facilitate mounting on the ear.

[0101] In the examples of this application, see Figure 1 As shown, the housing 10 may include an inner side 10a, an outer side 10b, a top side 10c and a bottom side 10d, wherein the inner side 10a may be arranged opposite to the outer side 10b, and the top side 10c may be arranged opposite to the bottom side 10d. For example, the top side 10c and the bottom side 10d are arranged opposite to each other in the first direction. Figure 1 The x direction in the figure can also be used as the thickness direction of the housing component 100, and the length direction of the housing component 100 is used as the second direction, such as Figure 1 In the y direction, the wearing end 101 and the connecting end 102 of the housing 10 can be arranged opposite to each other in the length direction, for example, the outer side surface 10b and the inner side surface 10a are opposite to each other in the third direction. Figure 1 The z direction in FIG. 1 can also be used as the width direction of the shell assembly 100. When the shell assembly 100 (temple) is worn, the inner side 10a of the shell 10 can fit the face (head) of the user, and the bottom side 10d can be the side of the shell 10 relatively close to the nose.

[0102] In order to achieve interaction with the user, such as language control, call and other functions, the glasses can also have a microphone, and a sound pickup port 15 can be opened on the shell 10 for collecting sound.

[0103] Figure 2 for Figure 1 Schematic diagram of the cross-sectional structure of the middle shell assembly along the AA plane.

[0104] Combination Figure 2 As shown, the housing 10 may have an accommodating cavity 14 inside. For example, the housing 10 may include a shell member 12 and a shell cover 17. The shell cover 17 is disposed on the shell member 12. The two together form the accommodating cavity 14. The accommodating cavity 14 can be used to accommodate a microphone.

[0105] The sound pickup port 15 on the shell 10 can be connected to the sound hole of the microphone in the accommodating cavity 14, so that the sound outside the shell assembly can be picked up by the sound pickup port 15 and transmitted to the microphone. The microphone can realize the conversion between sound signals and electronic signals, thereby realizing functions such as language control and call.

[0106] It is understandable that the effects of language control, call functions, etc. are closely related to the sound pickup effects of the microphone and the sound pickup port. When glasses and other devices are used outdoors in scenes with strong winds, such as strong winds, walking against the wind, cycling, etc., the wind flows through the user's head and glasses and other devices, and the generated vortex blows to the sound pickup port and the microphone, forming a pulsating pressure applied to the microphone. The microphone will pick up wind noise signals, such as annoying noise or noise, making it difficult for the other party to hear the content of the call, etc., affecting the normal use of the device and reducing the user experience. Therefore, wind noise reduction / wind noise prevention has also become one of the important difficult problems in the research of electronic equipment.

[0107] Based on this, a shell assembly provided in an embodiment of the present application achieves the purpose of reducing wind noise by setting a fluff structure on the outer shell, thereby preventing or reducing the wind noise problem of electronic equipment in windy scenes, significantly improving the sound pickup effect of the device microphone, ensuring the normal use of the device, and thus improving the user experience of the electronic device.

[0108] Continue to see Figure 2 As shown, a first sound pickup channel 11 may also be provided in the housing 10, and a sound pickup port 15 is connected to the first sound pickup channel 11, and the first sound pickup channel 11 is connected to the accommodating cavity 14, so that the first sound pickup channel 11 can be connected to the sound hole of the microphone in the accommodating cavity 14. In this way, the sound pickup port 15 is connected to the microphone in the accommodating cavity 14 through the first sound pickup channel 11.

[0109] The sound outside the shell assembly can be picked up by the sound pickup port 15 and transmitted to the microphone through the first sound pickup channel 11. Correspondingly, the wind noise signal also needs to pass through the sound pickup port 15 and the first sound pickup channel 11 before it can be transmitted to the microphone. The setting of the first sound pickup channel 11 can realize the diversion and attenuation of the wind noise signal, thereby achieving the effect of reducing wind noise.

[0110] The housing 10 may further include a second sound pickup channel 16 . The first sound pickup channel 11 is connected to the second sound pickup channel 16 . The second sound pickup channel 16 is connected to the accommodating chamber 14 . Thus, the first sound pickup channel 11 and the accommodating chamber 14 are connected via the second sound pickup channel 16 .

[0111] Exemplarily, the second sound pickup channel 16 may be a through hole, such as a through hole penetrating the shell 12 , one end of the second sound pickup channel 16 may be connected to the first sound pickup channel 11 , and the other end of the second sound pickup channel 16 may be connected to the accommodating cavity 14 .

[0112] It is understood that the structure illustrated in the embodiment of the present application does not constitute a specific limitation on the housing assembly. In other embodiments of the present application, the housing assembly may include more or fewer structural components than shown, or combine certain structural components, or split certain structural components, or arrange the structural components differently.

[0113] For example, the electronic device may further include a speaker, and the housing 10 of the housing assembly may further include a sound outlet 103 (see Figure 1 As shown in the figure, the accommodating cavity 14 can also be used to accommodate a speaker. The housing 10 can also have a sound outlet channel (not shown in the figure). The speaker can be connected to the sound outlet 103 through the sound outlet channel. The speaker can realize the conversion between electronic signals and sound signals. The generated sound can be transmitted through the sound outlet channel and the sound outlet 103 to realize functions such as call interaction and audio playback.

[0114] The electronic device may also include a circuit board. A data interface 104 may be provided on the shell 10 of the housing assembly. The accommodating cavity 14 may also be used to accommodate the circuit board. The circuit board may be connected to the data interface 104. The data interface 104 may be used to power the device. Alternatively, the data interface 104 may also be used to connect the device to an external multimedia device.

[0115] Of course, in some other examples, the accommodating cavity 14 can also be used to accommodate other structural components that can improve the functions of the electronic device. For example, the accommodating cavity 14 can also be used to accommodate circuit boards, sensors, etc.

[0116] Continue to see Figure 2 As shown, the housing assembly 100 further includes a fluff structure 20, which is fixed to the housing 10. Specifically, the fluff structure 20 can be formed by arranging a plurality of flexible fluffs, the fluffs are in a fiber state, and the flexible fluffs can swing and deform. For example, the fluffs can be fibers such as cotton fluff, wool, and leather, and have good swingability and softness. Of course, in some other examples, the fluffs can also be nylon, acrylic, polyester, or other types of fibers.

[0117] Figure 3 A schematic structural diagram of a fluff structure provided in an embodiment of the present application.

[0118] For example, see Figure 3 As shown, the fluff structure 20 may include a first adhesive layer 22 and a plurality of fluffs 21. The plurality of fluffs 21 may be fixed on one side of the first adhesive layer 22. The plurality of fluffs 21 may be fixed to the outer shell through the first adhesive layer 22, thereby achieving assembly of the fluff structure 20 on the outer shell.

[0119] Specifically, the fluff structure 20 can be arranged on at least one of the inner surface of the sound pickup port, the inner surface of the first sound pickup channel, and the outer surface of the part of the housing adjacent to the sound pickup port. It can be understood that when the wind flows through the housing of the shell assembly, it can enter the microphone from the sound pickup port and the first sound pickup channel to generate a wind noise signal. The fluff structure 20 is located on at least one of the inner surface of the sound pickup port, the inner surface of the first sound pickup channel, and the outer surface of the part of the housing adjacent to the sound pickup port. That is, the fluff structure 20 is arranged on the path from the wind to the microphone. The wind flows through the fluff structure 20. The fiber state of the fluff structure 20 can break up the large vortex generated by the wind flow and form a small vortex with less energy. The small vortex is easier to dissipate, thereby reducing the impact of the vortex. The fluff of the fluff structure 20 can swing and deform under the action of the wind flow, and the energy dissipation of the vortex is enhanced during the swinging process. Moreover, the fluff structure 20 is composed of a plurality of arranged fluffs, and has a relatively high density, which increases the friction energy consumption between the fluff structure 20 and the air, and can also dissipate the energy of the wind vortex, so that the fluff structure 20 can achieve a good wind noise reduction effect, reduce the wind noise signal of the microphone, ensure the normal use of electronic devices such as glasses in windy scenes, and improve the user experience. In addition, the fluff structure 20 can also refract and reflect the wind sound energy, and can also reduce the sound wave energy, further reducing the wind noise.

[0120] For example, refer to Figure 2 As shown, a fluff structure 20 may be provided on the inner surface of the first sound pickup channel 11, wherein Figure 2 It is shown that only one of the inner surfaces of the first sound pickup channel 11 is covered with a fluff structure 20. When the wind enters the first sound pickup channel 11 and is transmitted to the microphone in the accommodating cavity 14, the wind will flow through the fluff structure 20, so that the energy of the wind vortex can be consumed through the fluff structure 20, the effect of preventing wind noise is achieved, and the wind noise signal of the microphone is reduced.

[0121] Figure 4 A schematic structural diagram of another housing assembly provided in an embodiment of the present application.

[0122] For example, see Figure 4 As shown, a fluff structure 20 may also be provided on a portion of the outer surface of the shell 10 adjacent to the sound pickup port 15. The wind will come into contact with the shell 10 after passing through the shell assembly 100, and enter the microphone inside the shell 10 through the sound pickup port 15 on the shell 10. The fluff structure 20 is provided on a portion of the outer surface of the shell 10 adjacent to the sound pickup port 15. The wind enters the sound pickup port 15 after passing through the fluff structure 20. The fluff structure 20 can also be used to consume the energy of the wind vortex, thereby achieving the effect of preventing wind noise.

[0123] In addition, when the fluff structure 20 is located on the outer surface of the housing 10, the softness of the fluff structure 20 is conducive to improving the aesthetics of the housing assembly 100 and making the appearance of the housing assembly 100 more designable, and the soft fiber layer can also improve the comfort when wearing or using. For example, if the fluff structure 20 can be located on the inner side of the housing 10, the fluff structure 20 can help improve the wearing comfort of wearable devices such as glasses.

[0124] Correspondingly, a fluff structure 20 can also be set on the inner surface of the sound pickup port 15. When the wind vortex passes through the sound pickup port 15, it flows through the fluff structure 20 on the sound pickup port 15 and can also consume the energy of the wind vortex through the fluff structure 20 to achieve the effect of preventing wind noise.

[0125] It is understandable that the fluff structure can be provided on the inner surface of the sound pickup port, the inner surface of the first sound pickup channel, and the outer surface of part of the housing adjacent to the sound pickup port, which can achieve a good wind noise prevention effect. The fluff structure is provided on the inner surface of the sound pickup port, which can be provided on the entire inner surface of the sound pickup port, that is, the fluff structure completely covers the inner surface of the sound pickup port, or the fluff structure can be provided on part of the inner surface of the sound pickup port. Correspondingly, the fluff structure is provided on the inner surface of the first sound pickup channel, which can be provided on the entire inner surface of the first sound pickup channel, that is, the fluff structure completely covers the inner surface of the first sound pickup channel, or the fluff structure can be provided on part of the inner surface of the first sound pickup channel.

[0126] Alternatively, in some other examples, the fluff structure may also be provided on one of the inner surface of the sound pickup port, the inner surface of the first sound pickup channel, and a portion of the outer surface of the housing adjacent to the sound pickup port.

[0127] Of course, in some other examples, a fluff structure can also be provided on two of the inner surface of the sound pickup port, the inner surface of the first sound pickup channel, and a portion of the outer surface of the outer shell adjacent to the sound pickup port. For example, the inner surface of the sound pickup port and the inner surface of the first sound pickup channel can be covered with a fluff structure respectively, thereby simplifying the difficulty of assembly or molding design and helping to reduce costs while ensuring a good wind noise protection effect.

[0128] The following examples illustrate the structure of the housing and the structures of the first sound pickup channel and the sound pickup port.

[0129] Figure 5 A schematic diagram of the disassembled structure of an outer shell in a shell assembly provided in an embodiment of the present application.

[0130] For example, see Figure 5As shown, the housing 10 may include a housing member 12 and an assembly member 13, wherein the housing member 12 may include an installation wall 121, and the installation wall 121 is used to realize the assembly of the assembly member 13. The assembly member 13 may be covered on the installation wall 121 of the housing member 12, and the installation wall 121 may be a part of the outer surface of one side of the housing member 12. For example, the assembly member 13 is assembled on the installation wall 121, and a part of the outer surface 132 of the assembly member 13 and the outer surface of the housing member 12 may jointly form the outer side surface of the housing 10.

[0131] Accommodation cavity (refer to Figure 6 As shown in the figure, the second sound pickup channel 16 can be located in the shell 12, and a second sound pickup channel 16 can be opened on the installation wall 121. One end of the second sound pickup channel 16 can be located on the installation wall 121, and the other end of the second sound pickup channel 16 can extend into the shell 12 and communicate with the accommodating cavity in the shell 12.

[0132] Figure 6 A schematic diagram of the cross-sectional structure of an outer shell in a shell assembly provided in an embodiment of the present application.

[0133] Combination Figure 6 As shown, the assembly part 13 is fixedly mounted on the mounting wall 121, with the side of the assembly part 13 facing the mounting wall 121 being the inner surface 131 of the assembly part 13, and there is a gap between the inner surface 131 of the assembly part 13 and the mounting wall 121 of the housing 12 to form the first sound pickup channel 11, and the assembly part 13 can cover the opening of one end (the end located on the mounting wall 121) of the second sound pickup channel 16, so that the first sound pickup channel 11 and the second sound pickup channel 16 are connected. An opening can be opened on at least one of the assembly part 13 and the housing 12 to form a sound pickup port 15, as shown in FIG. Figure 6 As shown in , two openings can be respectively provided on the assembly part 13 to form a first sound pickup opening 151 and a second sound pickup opening 152. The first sound pickup opening 151 and the second sound pickup opening 152 can penetrate the inner surface 131 and the outer surface of the assembly part 13 to achieve the connection between the sound pickup opening 15 and the first sound pickup channel 11. In other words, the first sound pickup channel 11 and the sound pickup opening 15 are formed by the assembly design between the two independent structural parts of the assembly part 13 and the shell part 12, which is conducive to the structural design of the first sound pickup channel 11 and the sound pickup opening 15, and reduces the difficulty of structural design and production of the shell component.

[0134] Continue to see Figure 6As shown, the inner surface 131 of the fitting 13 can enclose a groove structure 13a. A convex structure 12b can be formed by protruding on a partial area of the mounting wall surface 121 of the housing part 12. The convex structure 12b and the groove structure 13a can cooperate with each other. When the fitting 13 is covered on the housing part 12, the convex structure 12b is received in the groove structure 13a, and there is a gap between the groove structure 13a and the convex structure 12b to form a first sound pickup channel 11.

[0135] Figure 7 It is a schematic front view of the cross-section of the outer shell in a housing assembly provided by an embodiment of the present application.

[0136] It can be understood that, in combination with Figure 6 and Figure 7 As shown, the convex structure 12b is formed by bending and protruding on the mounting wall surface 121 of the housing part 12, and the groove structure 13a is formed by bending and recessing the inner surface 131 of the fitting 13. Therefore, the first sound pickup channel 11 located between the convex structure 12b and the groove structure 13a can be designed in a bent structure. The first sound pickup channel 11 is a bent and extended curved channel, rather than a flat channel extending horizontally. It can extend the length of the first sound pickup channel 11 and extend the path length of the wind eddy current from the sound pickup port 15 to the accommodation cavity 14, and can well weaken the transmission of the pulsating pressure formed by the wind eddy current in the first sound pickup channel 11, thereby reducing the influence of wind noise on the microphone and achieving the effect of attenuating wind noise, further reducing the wind noise signal picked up by the microphone, and being more conducive to improving the wind noise reduction effect.

[0137] Exemplarily, the cross-section (the cross-section formed along the Figure 1 A-A plane in Figure 7 ) of the first sound pickup channel 11 can be in a shape similar to a C-shaped character as shown in

[0138]

[0139] Figure 7 Figure 7 As shown, there are more bent areas, which is more conducive to improving the wind noise reduction effect. Of course, in some other examples, the cross-section shape of the first sound pickup channel 11 can also be other regular or irregular shapes such as a shape similar to a C-shaped character or an arc shape. In the embodiment of the present application, there can be one sound pickup port, or there can also be two sound pickup ports. Among them, when there are two sound pickup ports, the two sound pickup ports can be respectively located on opposite sides of the outer shell, and the two sound pickup ports can be respectively communicated with the first sound pickup channel.

[0139] For example, continuing to refer to Figure 7 As shown, the two sound pickup ports can be a first sound pickup port 151 and a second sound pickup port 152. For example, the first sound pickup port 151 and the second sound pickup port 152 can be respectively located on the top side surface and the bottom side surface of the outer shell 10, the first sound pickup port 151 and the second sound pickup port 152 can be oppositely arranged along the first direction (x direction), and the first sound pickup port 151 and the second sound pickup port 152 can be respectively communicated with the first sound pickup channel 11.

[0140] The connected first sound pickup port 151 and second sound pickup port 152 can form a pressure relief design to reduce the influence of wind noise on the microphone 200. Specifically, the wind eddy can enter through the first sound pickup port 151, part of the wind eddy flows through the second sound pickup channel 16 into the accommodation cavity 14, and part of the wind eddy can flow out through the second sound pickup port 152 to achieve the effect of pressure relief, which can further reduce the wind noise signal picked up by the microphone 200 and further improve the wind noise reduction effect. Correspondingly, for the wind eddy entering through the second sound pickup port 152, part of it can flow out through the first sound pickup port 151, further improving the wind noise reduction effect.

[0141] Figure 8 It is a schematic structural diagram of a fitting in a housing assembly provided by an embodiment of the present application.

[0142] Specifically, referring to Figure 8 As shown, the fitting 13 can include a first side wall 135, a second side wall 134, and a third side wall 136. The first side wall 135 and the third side wall 136 can be located at both ends of the second side wall 134, and the first side wall 135 and the third side wall 136 can be oppositely arranged. For example, the first side wall 135 and the third side wall 136 can be oppositely arranged along the first direction, making the shape of the fitting 13 similar to a C shape or a U shape. The inner surfaces of the first side wall 135, the second side wall 134, and the third side wall 136 can enclose a groove structure 13a, which has a simple structure and is convenient for the realization of the groove structure 13a. Under the condition of forming a bent first sound pickup channel, it is beneficial to reduce the structural design and production difficulty of the fitting. Among them, the inner surface of the first side wall 135 is opposite to the inner surface of the third side wall 136, and the inner surface of the second side wall 134 is respectively connected to the inner surface of the first side wall 135 and the inner surface of the third side wall 136.

[0143] An opening can be formed on the fitting 13 to form a sound pickup port. For example, openings are respectively formed on the first side wall 135 and / or the third side wall 136 of the fitting 13 to form a sound pickup port, so that the sound pickup port is formed on the fitting, which is beneficial to the formation of the sound pickup port and is beneficial to reducing the structural design difficulty of the housing part and is easy to realize.

[0144] Exemplarily, continuing to refer to Figure 8 As shown, an opening can be formed at one end of the first side wall 135 facing away from the second side wall 134 to form a first sound pickup port 151. The first sound pickup port 151 can be a notch formed on the edge of one end of the first side wall 135 facing away from the second side wall 134.

[0145] An opening can be formed at one end of the third side wall 136 facing away from the second side wall 134 to form a second sound pickup port 152. The second sound pickup port 152 can also be a notch formed on the edge of one end of the third side wall 136 facing away from the second side wall 134.

[0146] Of course, in some other examples, the first sound pickup opening 151 may be a through opening on the end of the first side wall 135 facing away from the second side wall 134, and the through opening may not extend through the edge of the first side wall 135 facing away from the second side wall 134. The second sound pickup opening 152 may also not extend through the edge of the third side wall 136 facing away from the second side wall 134.

[0147] Alternatively, in some examples, an opening may be opened on the shell member to form a sound pickup port. For example, an opening may be opened on the outer surface of the shell member to form a sound pickup port, and the opening may extend to the mounting wall of the shell member to achieve communication between the sound pickup port and the first sound pickup channel.

[0148] Alternatively, in some examples, openings may be respectively provided on the shell member and the assembly member. For example, an opening may be provided on the end of the first side wall of the assembly member facing away from the second side wall, and the opening may be a notch on the edge of the end. An opening may also be provided on the side edge of the mounting wall surface of the shell member corresponding to the first side wall, and the opening may extend through to the outer surface of the shell member. When the assembly member cover is arranged on the shell member, the opening on the assembly member and the opening on the shell member are opposite to each other and together form a sound pickup port.

[0149] Fig. 9 A schematic diagram of the partial structure of a shell member in a shell assembly provided in an embodiment of the present application.

[0150] See also Fig. 9 As shown, in order to improve the assembly integration between the assembly part and the shell part, a coordination groove 12a can be opened on the outer surface of the shell part 12, and the protruding structure 12b can be formed by protruding on the inner bottom surface of the coordination groove 12a. The inner bottom surface of the remaining part of the coordination groove 12a and the outer surface of the protruding structure 12b can jointly form the installation wall surface of the shell part 12. The assembly part can be accommodated in the coordination groove 12a, so that the assembly part and the shell part 12 have a higher assembly integration, which is beneficial to improving the aesthetics of the shell 10.

[0151] An assembly groove may also be provided on the mounting wall surface of the shell member 12, such as an assembly groove 125 on the protruding structure 12b. The assembly groove 125 may cover the opening of the second sound pickup channel 16 on the mounting wall surface. The assembly groove 125 may be connected to the second sound pickup channel 16. The assembly groove 125 may be used to install a dustproof net to prevent dust and the like from entering the microphone from the second sound pickup channel 16, thereby ensuring the sound pickup effect of the microphone.

[0152] A raised fixing portion 124 may also be provided on the raised structure 12b. The fixing portions 124 may be located at both ends of the raised structure 12b along the second direction. The fixing portions 124 may be used to support the assembly and achieve a fixed connection with the assembly.

[0153] Fig.10 for Figure 1 Schematic diagram of the partial cross-sectional structure of the shell of the middle shell assembly along the BB plane.

[0154] For example, combined with Fig.10 As shown, an adhesive layer (not shown in the figure) can be formed on the fixing portion 124, the assembly part 13 is covered on the shell part 12, and the fixing portion 124 is supported between the assembly part 13 and the shell part 12 to ensure that the first sound pickup channel 11 and the sound pickup port can be formed between the assembly part 13 and the shell part 12. In addition, the assembly part 13 can be bonded and fixed to the fixing portion 124 through the adhesive layer to ensure the bonding strength between the assembly part 13 and the shell part 12.

[0155] Continue to combine Fig. 9 and Fig.10 As shown, a support portion 122 may also be provided on the mounting wall surface of the housing 12 (such as the protruding structure 12b), see Fig.10 As shown, the assembly part 13 is covered on the shell part 12, and the support part 122 can be located between the assembly part 13 and the shell part 12. The support part 122 plays a role in supporting the assembly part 13, especially when a first sound pickup channel 11 with a larger area is formed between the assembly part 13 and the shell part 12, the support part 122 can play a good supporting role for the assembly part 13, so as to reduce or avoid the problem that the assembly part 13 becomes dented during use, thereby affecting the appearance or even blocking the first sound pickup channel 11.

[0156] The number of microphones in the accommodating cavity 14 can be one, or the number of microphones can also be two, for example, they can be a first microphone and a second microphone respectively. The first microphone can be used as a main microphone to mainly pick up sound, and the second microphone can be used as a secondary microphone to assist in sound pickup, which can better improve the sound pickup effect and enable the device to have better sound pickup performance.

[0157] For example, when there are two microphones, see Fig.10 As shown, the accommodating cavity 14 may have two chambers, such as a first chamber 141 and a second chamber 142. The first chamber 141 may be used to accommodate a first microphone, and the second chamber 142 may be used to accommodate a second microphone. The first chamber 141 and the second chamber 142 may be distributed along the second direction, and the first chamber 141 may be disposed closer to the connecting end, and the second chamber 142 may be disposed closer to the wearing end.

[0158] There may also be two second sound pickup channels, such as the second sound pickup channel 16a and the second sound pickup channel 16b. The second sound pickup channel 16a may be connected to the first chamber 141, the second sound pickup channel 16b may be connected to the second chamber 142, and the first sound pickup channel 11 may be connected to the second sound pickup channel 16a and the second sound pickup channel 16b, respectively, so that the first sound pickup channel 11 is connected to the first microphone in the first chamber 141 and the second microphone in the second chamber 142, respectively.

[0159] Fig.11 A schematic diagram of the enlarged structure of a shell assembly at a sound pickup port provided in an embodiment of the present application.

[0160] It can be understood that, taking the outer shell component as a temple as an example, the outer shell 10 is relatively long (the length along the second direction), and the length of the sound pickup port and the first sound pickup channel (not shown in the figure) along the second direction can also be relatively long. Fig.11 As shown, taking the first sound pickup opening 151 as an example, the first sound pickup opening 151 may be a long strip-shaped slot structure, and the first sound pickup channel may also be a slot-shaped channel (refer to Figure 7 As shown), it has a narrow gap width. The first sound pickup channel is a flat and long gap structure, which can have a smaller gap width and a larger area. The first sound pickup channel has a larger air resistance, which can further weaken the transmission of the pulsating pressure of the wind vortex in the first sound pickup channel, and optimize the wind noise reduction effect. Moreover, the wind vortex will become laminar flow when entering from the narrow sound pickup port 15 and the first sound pickup channel, which can also reduce the impact of wind noise on the microphone. It is also beneficial to increase the coverage area of ​​the fluff structure at the sound pickup port and the first sound pickup channel, further achieving a better wind noise reduction effect.

[0161] The following examples illustrate the assembly of the fleece structure with the shell and the structural properties of the fleece structure.

[0162] The fluff structure can be set on the assembly part 13, and the outer shell 10 is formed by assembling the assembly part 13 and the shell part 12 to achieve the fixation of the fluff structure on the outer shell 10. The structural design of the assembly part 13 is relatively simple, so that the fluff structure is set on the assembly part 13, which can facilitate the forming and assembly of the fluff structure, thereby helping to reduce the difficulty of forming or assembling the fluff structure on the outer shell 10.

[0163] Of course, in some other examples, the fluff structure can also be set on the shell part 12. For example, the installation wall surface of the shell part 12 can also be covered with the fluff structure. After the assembly part 13 is fixed to the shell part 12, the inner surface of one side of the first pickup channel has the fluff structure.

[0164] Alternatively, in some other examples, the fluff structure may also be provided on the shell cover, for example, the fluff structure may be provided on a portion of the outer surface of the shell cover adjacent to the sound pickup port.

[0165] Alternatively, in some other examples, a fluff structure may be provided on at least two of the shell 12, the shell cover and the assembly 13. For example, the inner surface 131 of the assembly 13 and the side of the coordination groove facing the assembly 13 may be covered with the fluff structure respectively, so that the inner surface of the first sound pickup channel is provided with the fluff structure, and the fluff structure completely covers the inner surface of the first sound pickup channel.

[0166] In the embodiment of the present application, the fluff structure is provided on the assembly part as an example for description.

[0167] Specifically, at least one of the inner surface of the first sound pickup opening, the inner surface of the second sound pickup opening, the inner surface of the assembly, and the outer surface of the assembly can be covered with a fluff structure. Thus, the fluff structure is arranged on at least one of the inner surface of the sound pickup opening, the inner surface of the first sound pickup channel, and the outer surface of the housing adjacent to the sound pickup opening, which facilitates the assembly or forming of the fluff structure on the housing while ensuring a good wind noise reduction effect, and helps reduce noise reduction costs.

[0168] It can be understood that the covering here can be complete covering or partial covering, wherein the fluff structure is completely covered on at least one of the inner surfaces of the first sound pickup port and the second sound pickup port, the inner surface of the assembly, and the outer surface of the assembly, which can facilitate the setting of the fluff structure and help improve the wind noise reduction effect.

[0169] Fig.12 A schematic diagram of the assembly structure of an assembly part and a fluff structure provided in an embodiment of the present application.

[0170] Exemplarily, the fleece structure may be coated on the inner surface of the fitting, for example, see Fig.12 As shown, the inner surface 131 of the assembly part 13 can be completely covered with the fluff structure 20, and a first sound pickup channel is formed between the inner surface 131 and the shell part, so that the inner surface of one side of the first sound pickup channel has the fluff structure 20.

[0171] Fig.13 A schematic diagram of the assembly structure of another assembly part and a fluff structure provided in an embodiment of the present application.

[0172] Alternatively, the fluff structure may also cover the inner surfaces of the first sound pickup opening and the second sound pickup opening, for example, see Fig.13 As shown, taking the first sound pickup opening 151 and the second sound pickup opening 152 as the notches on the edges of the first side wall and the third side wall of the assembly 13 respectively, the inner surfaces of the first sound pickup opening 151 and the second sound pickup opening 152 can be covered with a fluff structure 20 respectively, and the fluff structure 20 can completely cover the first sound pickup opening 151 and the second sound pickup opening 152.

[0173] It should be noted that, in some other examples, only the inner surface of one of the sound pickup ports may be covered with a fluff structure, which can also achieve the effect of reducing wind noise.

[0174] Fig.14 A schematic diagram of an assembly structure of another assembly part and a fluff structure provided in an embodiment of the present application.

[0175] Alternatively, the fluff structure can also be covered on the outer surface of the assembly part, the assembly part is fixed on the shell part, the outer surface of the assembly part can be used as a part of the outer surface of the shell, and the first sound pickup port and the second sound pickup port are formed between the assembly part and the shell part, for example, see Fig.14 As shown, the outer surface 132 of the assembly 13 can be completely covered with the fluff structure 20, and the outer surface 132 can serve as a portion of the outer surface of the shell 10 adjacent to the first sound pickup port and the second sound pickup port, that is, the portion of the outer surface of the shell 10 adjacent to the first sound pickup port and the second sound pickup port are both provided with the fluff structure 20.

[0176] Fig.15 A schematic diagram of the assembly structure of another assembly part and a fluff structure provided in an embodiment of the present application.

[0177] Alternatively, the inner surface, the outer surface of the assembly, and the inner surfaces of the first sound pickup opening and the second sound pickup opening may all be covered with a fluff structure, for example, see Fig.15 As shown, the inner surface 131 of the assembly 13 can be completely covered with the fluff structure 20, the outer surface 132 can also be completely covered with the fluff structure 20, the inner surface of the first sound pickup port 151 and the inner surface of the second sound pickup port 152 can also be completely covered with the fluff structure 20, so that the first sound pickup channel, the first sound pickup port, the second sound pickup port, and the outer surfaces of parts adjacent to the first sound pickup port and the second sound pickup port are all provided with the fluff structure 20, which has a better wind noise reduction effect.

[0178] Of course, in some other examples, the fluff structure 20 may also be covered on two of the inner surface 131, the outer surface 132, the inner surface of the first sound pickup port 151, and the inner surface of the second sound pickup port 152 of the assembly 13. For example, the fluff structure 20 may be covered on the inner surface 131 of the assembly 13, the inner surface of the first sound pickup port 151, and the inner surface of the second sound pickup port 152, respectively. While ensuring a good wind noise reduction effect, the coverage amount of the fluff structure 20 is reduced, which is beneficial to reducing costs, facilitating implementation, and reducing the difficulty of molding.

[0180] See also Fig.16 As shown, it should be noted that Fig.16 S11 and S12 are wind noise signal frequency response curves of the second microphone in the comparison group (repeated simulation), and the comparison group may be a shell assembly without a fluff structure. S21 and S22 are wind noise signal frequency response curves of the second microphone in a shell assembly with a fluff structure, where the fluff structure is provided on the inner surface of the assembly, the inner surface of the first sound pickup port, and the inner surface of the second sound pickup port as an example.

[0181] Depend on Fig.16 It can be seen that in the first scenario, in the shell assembly provided with a fluff structure, the second microphone can pick up a relatively small wind noise signal, that is, it has a better wind noise reduction effect. The specific wind noise signal frequency response comparison is shown in Table 1.

[0182] Table 1 shows a comparison of wind noise signal frequency responses of a second microphone in a shell assembly provided in an embodiment of the present application in a first scenario.

[0183] Frequency(Hz) 50 100 150 200 300 400 No fluff structure is set -51.63 -56.26 -59.11 -62.5 -63.11 -72.82 Setting the fluff structure -56.65 -59.93 -62.51 -65.87 -66.37 -75.33 Difference 5 3.7 3.4 3.3 3.2 2.5

[0184] Fig.17 A wind noise signal frequency response comparison diagram of a second microphone in a shell assembly in a second scenario provided in an embodiment of the present application, wherein the second scenario refers to a simulated usage scenario of the device at a wind speed of 5 m / s.

[0185] Accordingly, Fig.17 S11 and S12 are wind noise signal frequency response curves of the second microphone in the comparison group, and the comparison group may be a housing assembly without a fluff structure. S21 and S22 are wind noise signal frequency response curves of the second microphone in a housing assembly with a fluff structure, where the fluff structure is provided on the inner surface of the assembly, the inner surface of the first sound pickup port, and the inner surface of the second sound pickup port as an example.

[0186] Depend on Fig.17 It can be seen that in the second scenario, in the housing assembly provided with the fluff structure, the second microphone can pick up a relatively small wind noise signal, that is, it has a good wind noise reduction effect. The following Table 2 shows the comparison of the wind noise energy gain of the second microphone in the two scenarios in the 100kHz-8kHz frequency band.

[0187] Table 2 shows a comparison of wind noise energy gains of a second microphone in a housing assembly provided in an embodiment of the present application.

[0188] 5m / s wind speed 10m / s wind speed No fluff structure is set -47.2 -29.8 Setting the fluff structure -50.7 -33.5 income -3.4 -3.7

[0189] It can be seen from Table 2 that compared with the case without a fluff structure, the wind noise signal energy of the second microphone in the shell assembly with a fluff structure is reduced by about 3.4dB to 3.7dB, which has a good wind noise reduction effect, helps to ensure the sound pickup effect of the second microphone, and improves the user experience.

[0190] In some examples, the pile structure may include a plurality of piles and a first adhesive layer (see Figure 3 As shown), a plurality of fluffs can be fixed to the outer shell by a first adhesive layer.

[0191] Fig.18 A schematic structural diagram of another fluff structure provided in an embodiment of the present application.

[0192] Or, in some examples, see Fig.18 As shown, the pile structure 20 may include a plurality of piles 21 and a substrate 23. The piles 21 may be fixed on one side of the substrate 23, and the side of the substrate 23 facing away from the piles 21 may be fixed to the assembly part, so that the pile structure 20 is fixedly assembled to the assembly part through the substrate 23. The pile structure is fixed to the assembly part through the substrate, which is conducive to improving the assembly stability of the pile structure.

[0193] The substrate 23 and the assembly part can be fixed by means of an adhesive connection. For example, it can also include a second adhesive layer 24. The second adhesive layer 24 can be arranged between the side of the substrate 23 facing away from the fluff 21 and the outer shell, so that the substrate 23 and the assembly part are fixed by the second adhesive layer 24, and the fluff structure 20 is also fixed to the assembly part.

[0194] The fluff 21 and the substrate 23 may also be fixed by adhesive connection. For example, the fluff structure 20 may also include a third adhesive layer 26 . The third adhesive layer 26 is located on one side of the substrate 23 , and the fluff 21 is fixed on one side of the substrate 23 through the third adhesive layer 26 .

[0195] A release film 25 may also be included, and the release film 25 may be adhered to the side of the second adhesive layer 24 facing away from the substrate 23. When the villi structure 20 is assembled to the assembly part, the release film 25 may be torn off, and then the villi structure 20 may be assembled through the second adhesive layer 24. The release film 25 may protect and isolate the second adhesive layer 24, and may prevent the villi structure 20 or the assembly part from being adhered to other parts through the second adhesive layer 24 during assembly, transportation or use, thereby improving the convenience during assembly and use.

[0196] It is understandable that the pile structure 20 may include the second adhesive layer 24 and the release film 25, and during assembly, the pile structure 20 may be directly adhered to the assembly part through the second adhesive layer 24. Of course, in some other examples, the assembly part (housing) may include the second adhesive layer 24 and the release film 25, and the bonding and fixing between the substrate 23 and the assembly part can be achieved.

[0197] Alternatively, the substrate 23 and the assembly part can be fixed in a convenient and detachable manner. For example, a hanging ear can be provided on one side of the substrate 23 facing away from the fluff 21 and one of the assembly parts, and a hanging position can be provided on the other side. The hanging ear can cooperate with the hanging position, so that the substrate 23 can be hung on the assembly part, and the fluff structure 20 can be fixed on the assembly part. The assembly method is simple and fast. Moreover, the fluff structure 20 can also be conveniently removed from the assembly part to meet the scene where the fluff structure 20 is not needed, which improves the flexibility of the assembly design between the fluff structure 20 and the assembly part and improves the applicable scope of the fluff structure 20.

[0198] For example, the ear hook portion may be a protrusion, and the hanging position may be a groove that can accommodate and fix the protrusion. For example, if a fluff structure is provided on the outer surface of the assembly part, the protrusion may be formed on the side of the substrate 23 facing away from the fluff 21, and the groove may be formed on the outer surface of the assembly part. When assembling the fluff structure 20, the protrusion on it is extended into the groove fixed on the assembly part, so that the fluff structure 20 can be hung on the assembly part.

[0199] The length of the fluff 21 in the fluff structure 20 can be 0.3 mm to 1 mm, and the fiber length is relatively short. Under the premise of ensuring a good wind noise reduction / wind noise prevention effect, it can be easily assembled on a shell component with a relatively small volume.

[0200] Exemplarily, the length of the flexible fluff 21 can be 0.3 mm to 0.8 mm, which can ensure a good wind noise reduction effect while also ensuring that the device has a good sound pickup effect, thereby helping to improve the performance of the device.

[0201] For example, the fluff structure 20 can be a flocking layer, that is, the fluff structure 20 can be a fiber layer formed by a flocking process. For example, the fluff 21 (such as short fibers obtained from waste fibers by grinding or cutting, with a length of 0.3mm to 0.8mm) can be vertically fixed on an object (such as a shell) or a substrate 23 coated with an adhesive (such as the first adhesive layer 22 mentioned above) to form a flocking layer.

[0202] The density of the fluff 21 in the fluff structure 20 can be 2-3 k / mm 2 , which can ensure that the fluff structure 20 has a good wind noise reduction effect, can also ensure that the device has a good sound pickup effect, and is conducive to reducing costs.

[0203] It can be understood that the specific setting position of the fluff structure 20, the length of the fluff 21 in the fluff structure 20, the fluff density, the fluff material, etc. can be selected and set according to the distribution of wind vortices that the wearable device is subjected to when worn in the specific application scenario. For example, the specific position of the fluff structure 20, the length, density, material, etc. of the fluff can be matched according to the simulated vortex shedding distribution diagram of the wearable device at the assembly position.

[0204] For example, the length of the fluff 21 of the fluff structure 20 located on the sound pickup port can be greater than or equal to the width of the sound pickup port, wherein the width of the sound pickup port can refer to the sum of the depths of the openings forming the sound pickup port. For example, taking the example of forming the first sound pickup port by opening an opening (notch) at the edge of one end of the first side wall of the assembly facing away from the second side wall, the depth of the notch is the width of the first sound pickup port. The assembly is fixed to the shell member, and the end surface of the first side wall facing away from the second side wall is flush with the installation wall surface. The distance between the bottom surface of the first sound pickup port (the side opposite to the installation wall surface) and the installation wall surface is the width of the first sound pickup port (see Figure 7 h) in.

[0205] The length of the fluff 21 is greater than the gap width of the sound pickup port, that is, the fluff structure 20 on the sound pickup port has an interference fit with the sound pickup port, and the fluff 21 fills the entire sound pickup port, which is beneficial to improving the wind noise protection effect at the sound pickup port, thereby improving the wind noise reduction effect of the entire device and improving the user experience.

[0206] It should be noted that the length of the fluff 21 can correspond to the size of the vortex distribution. For example, in the simulated vortex diagram, the position of the assembly part with a large vortex can be covered with a fluff structure 20 with a longer length of fluff 21, and the position of the assembly part with a small vortex can be covered with a fluff structure 20 with a smaller length of fluff 21.

[0207] Exemplarily, Table 3 shows examples of the characteristics of the matching fluff structures 20 and 21 on the assembly parts. The fluff structures 20 in each example can give the shell assembly and the wearable device a better wind noise protection / wind noise reduction effect, and can ensure that the device has a better sound pickup effect, significantly improving the performance and user experience of the device.

[0208] Table 3 is an example of the corresponding matching fluff structure performance on the assembly provided in the embodiment of the present application.

[0209]

[0210]

[0211] It should be noted that the fluff is cut leather or polyester, which is coarser and softer than other materials, and the fluff is cut acrylic, which is finer and harder than other materials.

[0212] In order to ensure the long-lasting wind noise reduction effect of the fluff structure 20, the fluff structure 20 may also include a modification structure, which may be covered on the multiple fluffs 21, and the molding material of the modification structure may include at least one of a hydrophobic material, an oleophobic material, and a hydrophobic and oleophobic material. For example, the modification structure may be a film layer formed by at least one of a hydrophobic material, an oleophobic material, and a hydrophobic and oleophobic material, and the film layer is covered on the multiple fluffs 21, such as covering the outer surface of the fluff 21, wrapping the fluff 21, so that the entire fluff structure 20 can have at least one of hydrophobic and oleophobic properties, reducing or avoiding the influence of sweat on the fluff structure 20 during the wearing or use of the shell component, and ensuring that the fluff structure 20 can achieve a long-lasting, stable and reliable wind noise reduction effect.

[0213] For example, the molding material of the modified structure may include at least one of polymethacryloxypropyl cage-type polysilsesquioxane (also known as polymethacryloxypropyl POSS), perfluorooctadecyl trichlorosilane, and perfluoro polymethyl methacrylate, which can give the fluff structure 20 a good hydrophobic and oleophobic effect, so that the fluff structure 20 has both hydrophobic and oleophobic properties, and better ensure the wind noise reduction effect of the fluff structure 20.

[0214] The hydrophobic angle of the fluff structure 20 can be greater than 120°, which refers to the angle between the liquid and the solid-liquid boundary line when the tangent line of the gas-liquid interface at the intersection of the gas, liquid and solid phases passes through the fluff structure 20. The fluff structure 20 has a good hydrophobic effect, which further ensures the wind noise reduction effect of the fluff structure 20 during use.

[0215] The oleophobic angle of the fluff structure 20 can be greater than 90°, which refers to the angle between the liquid and the solid-liquid boundary line when the tangent line of the gas-liquid interface at the gas-liquid-solid three-phase intersection point passes through the oily liquid when the oily liquid is lowered onto the fluff structure 20, wherein the oily liquid can be an oily liquid simulating human sebum. The fluff structure 20 has a good oleophobic effect, further ensuring the wind noise reduction effect of the fluff structure 20 during use.

[0216] Fig.19 A schematic diagram of the structure of an accessory provided in an embodiment of the present application.

[0217] See also Fig.19As shown, an embodiment of the present application also provides an accessory 300 for an electronic device, the accessory 300 may include the above-mentioned fluff structure 20, the accessory 300 may be assembled to a shell assembly of the electronic device, the shell assembly may include the above-mentioned shell, the accessory 300 may be fixed to at least one of the inner surface of the sound pickup port of the shell, the inner surface of the first sound pickup channel and a portion of the outer surface of the shell adjacent to the sound pickup port, thereby fixing the fluff structure 20 on the shell.

[0218] For example, taking the example of accessory 300 being fixedly assembled on the outer surface of the assembly of the shell, the shape of accessory 300 can correspond to the shape of the outer surface of the assembly, and the accessory 300 can be fixed on the outer surface of the assembly so that the outer surface of the assembly has a fluff structure 20. After the wind flows through the fluff structure 20, it enters the sound pickup port, and the fluff structure 20 can play a good role in reducing wind noise.

[0219] The fixing method of the accessory 300 and the shell can refer to the fixing method of the fluff structure and the shell (assembly part) mentioned above, which will not be repeated here.

[0220] Fig. 20 A flow chart of a method for preparing a shell assembly provided in an embodiment of the present application.

[0221] The embodiment of the present application also provides a method for preparing a shell assembly, which is used to manufacture the above-mentioned shell assembly.

[0222] For details, see Fig. 20 As shown, the preparation method may include:

[0223] S101: Provide a housing.

[0224] A sound pickup port is provided in the shell, a receiving cavity and a first sound pickup channel are provided in the shell, the sound pickup port is communicated with the first sound pickup channel, and the first sound pickup channel is communicated with the receiving cavity.

[0225] S102: Arrange a fluff structure on at least one of the inner surface of the sound pickup port, the inner surface of the first sound pickup channel, and a portion of the outer surface of the housing adjacent to the sound pickup port.

[0226] The above method can obtain a housing component with a fluff structure, which can reduce wind noise, ensure the normal use of electronic equipment in windy scenes, ensure the sound pickup effect of the equipment, and improve the user experience. The method is simple in process, easy to implement, and conducive to reducing production costs.

[0227] In some examples, the fluff can be directly fixed on the shell to form a fluff structure on the inner surface of the sound pickup port, the inner surface of the first sound pickup channel, and a portion of the outer surface adjacent to the sound pickup port of the shell, thereby achieving fixed assembly of the fluff structure on the shell. Exemplarily, the method for preparing the shell assembly may also include:

[0228] S101a: Provide fluff.

[0229] Step S102 may include: fixing the fluff on at least one of the inner surface of the sound pickup port, the inner surface of the first sound pickup channel, and a portion of the outer surface of the housing adjacent to the sound pickup port to form a fluff structure.

[0230] For example, taking the example of a fluff structure including fluff and a first adhesive layer, the first adhesive layer can be first formed on the inner surface of the sound pickup port of the shell, the inner surface of the first sound pickup channel, and part of the outer surface adjacent to the sound pickup port, and then the fluff is fixed on the first adhesive layer, so that the fluff structure is directly formed on the shell, realizing the assembly setting of the fluff structure, and the molding method of the entire shell assembly is relatively simple.

[0231] It is understandable that there may be no order between step S101a and step S101.

[0232] Alternatively, in some examples, the fluff structure may be provided first, and then the fluff structure may be fixed on the shell. Exemplarily, the method for preparing the shell assembly may further include:

[0233] S101b: Provide a villi structure.

[0234] Step S102 may include: fixing the fluff structure on at least one of the inner surface of the sound pickup port, the inner surface of the first sound pickup channel, and a portion of the outer surface of the housing adjacent to the sound pickup port.

[0235] For example, taking the example of a fluff structure including fluff and a first adhesive layer, the fluff can be first fixed on the first adhesive layer to form the fluff structure, and then the fluff structure is fixed to the shell through the first adhesive layer, which has high flexibility and helps to reduce the difficulty of molding the shell assembly.

[0236] After step S102, the method for preparing the housing assembly may further include:

[0237] S103: drying, brushing and arranging the fluff structure in sequence.

[0238] The adhesive layer (such as the first adhesive layer) and the villi structure can be dried by drying, and then the floating hair (unfixed villi) on the villi structure can be removed by brushing, and then the performance and aesthetics of the entire villi structure can be improved by arranging the villi structure.

[0239] To impart hydrophobic and / or oleophobic properties to the fluff structure, the method may further comprise:

[0240] S104: performing at least one of a hydrophobic treatment and an oleophobic treatment on the villi structure.

[0241] For example, the villi structure can be treated with an amphiphobic treatment using a modifier such as polymethacryloxypropyl POSS, perfluorooctadecyltrichlorosilane or perfluoropolymethyl methacrylate, so that a modified structure is formed on the villi structure, giving the villi structure an amphiphobic property.

[0242] It should be noted that step S104 can be implemented after step S102, that is, after the fluff structure is provided on the shell, the fluff structure is subjected to hydrophobic and / or oleophobic treatment. Step S104 can be implemented in the fluff arranging stage of step S103, that is, the fluff is subjected to hydrophobic and / or oleophobic treatment during the process of combing the fluff. Alternatively, step S104 can also be implemented before or after step S103.

[0243] Alternatively, in the example of the method of first providing the fluff structure and then fixing the fluff structure on the housing, the fluff structure may be first subjected to hydrophobic and / or oleophobic treatment and then disposed on the housing. That is, step S104 may be implemented between step S101b and step S102.

[0244] Alternatively, the fluff structure may be treated to be hydrophobic and / or oleophobic when the fluff structure is formed. For example, in the example where the fluff is fixed on an outer shell to form the fluff structure, the fluff structure may be treated to be hydrophobic and / or oleophobic while the fluff structure is formed on the outer shell. For example, the fluff may be treated to be hydrophobic and / or oleophobic during the flocking process, that is, step S102 and step S104 may be performed simultaneously.

[0245] In this embodiment, the outer shell may be an integrally formed structural component, or the outer shell may be composed of the above-mentioned assembly component and shell component.

[0246] When the housing includes a shell member and an assembly member, step S101 may include:

[0247] S111: Provide assembly parts and housing parts.

[0248] The shell member may have a mounting wall surface, and the shell member may have a receiving cavity inside. The specific structures of the shell member and the assembly part can be found above and will not be described in detail here.

[0249] S121: The assembly part is covered on the installation wall, with a gap between the inner surface of the assembly part and the installation wall to form a first sound pickup channel, and at least one of the assembly part and the shell part is provided with an opening to form a sound pickup port.

[0250] Step S102 may include: providing a fluff structure on the assembly part.

[0251] The above method can be used to fix the fluff structure on the assembly part. The fluff structure is provided on the assembly part with a relatively simple structure, which is helpful to simplify the molding steps and molding difficulty of the shell component.

[0252] The specific position of the fluff structure on the assembly can also be seen above, and will not be repeated here. For example, the fluff structure can be arranged on the inner surface of the assembly, the outer surface of the assembly, and the inner surfaces of the first sound pickup opening and the second sound pickup opening of the assembly.

[0253] Fig.21 A schematic diagram of a process flow of a shell assembly provided in an embodiment of the present application.

[0254] Exemplarily, taking a substrate as a fabric such as cloth, first forming a fluff structure and then assembling it onto a shell as an example, the preparation process flow of the shell assembly is described.

[0255] See also Fig.21 As shown, first prepare the substrate 23, such as cleaning and drying the surface of the cloth fabric. Then perform the gluing operation. For example, the surface of the fabric can be coated with glue to form a third adhesive layer, wherein the gluing process can be to form a third adhesive layer by coating the adhesive on the surface of the fabric. The reliability, bonding reliability, humidity / temperature, oil resistance and other properties of the adhesive can be tested multiple times during the gluing process to pursue the optimal bonding fastness. After gluing, flocking is performed, such as by using an electrostatic flocking machine to fix the fluff 21 on the surface of the fabric by a flocking process, and the fluff can be treated with hydrophobic and oleophobic treatment during the flocking process. Then perform drying, brushing, finishing and other treatments to form a fluff structure 20, and paste the fluff structure 20 on the shell to obtain a shell assembly.

[0256] It should be noted that the numerical values ​​and numerical ranges involved in the embodiments of the present application are approximate values ​​and may have a certain range of errors, which can be considered negligible by those skilled in the art.
