Description

Temple of glasses, glasses and wearable device Technical Field

[0001] The present application relates to the field of terminal technology, and in particular to a pair of temples, glasses, and wearable devices. 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, virtual reality or augmented reality experience, etc., and have gradually become one of the more common wearable electronic devices in smart life.

[0003] Taking smart glasses as an example, the glasses may include temples that can be worn on the user's head, such as by resting the temples on the ears. The temples may include a housing and a microphone. The housing may include a cavity, and a sound pickup hole may be provided in the housing. The sound hole of the microphone is connected to the sound pickup hole. The sound produced by the user can enter the microphone through the sound pickup hole and be converted into an electronic signal, enabling voice interaction functions such as phone calls on the device.

[0004] When glasses and other devices are used in windy environments 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.

[0005] Utility Model Content

[0006] The embodiments of the present application provide a temple, glasses, and a wearable device. The bending design of the first sound pickup channel inside the temple can weaken the transmission of pulsating pressure formed by external wind vortices, achieve the effect of reducing wind noise, ensure the normal use of the device in windy scenes, and significantly improve the user experience.

[0007] A first aspect of an embodiment of the present application provides a temple, comprising a housing, wherein an outer surface of the housing has a mounting wall, and a housing within the housing corresponding to the mounting wall has a housing for accommodating a microphone. The temple further comprises a fairing, the fairing being disposed on the mounting wall, and a gap being formed between the inner surface of the fairing and the mounting wall to form at least one first sound pickup channel, the first sound pickup channel being connected to the housing, and at least one of the fairing and the housing being provided with a first sound pickup port and a second sound pickup port, the first sound pickup port and the second sound pickup port being respectively connected to the first sound pickup channel, and the first sound pickup port and the second sound pickup port being respectively located on either side of the housing. After wind vortices are picked up by the first sound pickup port and the second sound pickup port, they must pass through the first sound pickup channel before being transmitted to the microphone. The provision of the first sound pickup channel can attenuate wind noise signals entering the temple, thereby reducing wind noise, reducing the wind noise signals picked up by the microphone, improving the microphone's sound pickup effect, ensuring normal use of glasses and other devices in windy scenes, and enhancing the user experience.

[0008] In addition, by covering the outer surface of the shell with a fairing, a first sound pickup channel, a first sound pickup port and a second sound pickup port can be formed. The structural design is simple and easy to implement, and will not affect the structural design and layout of the inner shell of the temple. It only needs to cover the outer surface of the shell with a fairing, which reduces the difficulty of structural design and production of the temple, facilitates promotion and implementation, and reduces the difficulty and cost of implementing wind noise protection design on the temple.

[0009] In one possible implementation, the inner surface of the fairing is formed into a groove structure, and a portion of the mounting wall is raised to form a raised structure that mates with the groove structure. A gap is formed 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 housing, and the groove structure is formed by a curved depression on the inner surface of the fairing. Therefore, the first sound pickup channel located between the raised structure and the groove structure can be designed as a curved structure. In other words, the first sound pickup channel is a curved channel that extends in a curved manner, rather than a flat channel extending horizontally. This can extend the length of the first sound pickup channel and the path length of the wind vortex from the first and / or second sound pickup ports to the accommodating cavity. This can effectively weaken the transmission of the pulsating pressure generated by the wind vortex within the first sound pickup channel, reduce the impact of wind noise on the microphone, achieve the effect of attenuating wind noise, further reduce the wind noise signal picked up by the microphone, and further improve the wind noise reduction effect, ensuring the normal use of the glasses in windy scenes.

[0010] In one possible implementation, the fairing 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 to each other. 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 facilitates the implementation of the groove structure. Under the condition of forming a bent first sound pickup channel, it is beneficial to reduce the structural design and production difficulty of the fairing.

[0011] A first sound pickup port is provided at one end of the first side wall facing away from the second side wall, and a second sound pickup port is provided at one end of the third side wall facing away from the second side wall, so that the two sound pickup ports are provided on the fairing, and no opening is required on the outer shell to form the sound pickup ports, thereby further reducing the impact on the structural layout of the outer shell and facilitating the protection of the various structural components within the accommodating cavity of the outer shell.

[0012] In one possible implementation, a second sound pickup channel is provided on the mounting wall, communicating with both the first sound pickup channel and the accommodating cavity. This facilitates communication between the first sound pickup channel and the accommodating cavity when the fairing is mounted on the mounting wall to form the first sound pickup channel. The structural design is simple and facilitates production and assembly.

[0013] In a possible implementation, the first sound pickup channel includes at least one bent section, where the bent section refers to a portion of the channel that is bent rather than straight, and can be understood as being formed by bending a straight channel to have a certain bending angle.

[0014] The bend is located between at least one of the first and second sound pickup ports and the second sound pickup channel, and at least one of the first and second sound pickup ports is connected to the second sound pickup channel via the bend. In other words, as the wind vortex flows from the first and second sound pickup ports into the second sound pickup channel (microphone), it passes through at least one bend. This effectively extends the transmission path of the wind vortex, ensuring that the pulsating pressure generated by the wind vortex is reduced while being transmitted within the first sound pickup channel, thereby effectively attenuating wind noise.

[0015] In one possible implementation, the first sound pickup channel includes a first transverse section, a vertical section, and a second transverse section connected in sequence. A bend section is connected between the first transverse section and the vertical section, and another bend section is connected between the second transverse section and the vertical section. The first sound pickup port is in communication with the first transverse section, the second sound pickup port is in communication with the second transverse section, and the vertical section is in communication with the second sound pickup channel. In other words, there is a first bend section between the first sound pickup port and the second sound pickup channel, and a second bend section between the second sound pickup port and the second sound pickup channel, ensuring that wind entering from the first sound pickup port and the second sound pickup port must flow through a bend section before entering the second sound pickup channel. This can better weaken the transmission of pulsating pressure formed by wind vortexes within the first sound pickup channel, ensuring that wind noise has a smaller impact on the microphone. In addition, the structural design is relatively simple, making it easy to produce and implement.

[0016] In one possible implementation, the extension direction of the first sound pickup opening intersects with the extension direction of the first transverse section, forming a bend at the connection point between the first sound pickup opening and the first transverse section. The extension direction of the second sound pickup opening intersects with the extension direction of the second transverse section, forming a bend at the connection point between the second sound pickup opening and the second transverse section. This can further increase the path of wind noise from the sound pickup opening to the microphone, weaken the transmission of pulsating pressure from the eddy current in the first sound pickup channel, further reduce the impact of wind noise, achieve a more excellent wind noise reduction effect, and significantly improve the microphone's sound pickup effect.

[0017] In one possible implementation, the housing cavity includes a first chamber and a second chamber, each of which is used to accommodate a microphone. The second sound pickup channel is provided with two channels, a first channel and a second channel, the first channel communicating with the first chamber, and the second channel communicating with the second chamber. This allows for two microphones to be installed within the temple, with the first microphone serving as a primary microphone and the second microphone serving as a secondary microphone. This improves sound pickup and enhances the device's sound pickup performance.

[0018] In one possible implementation, there is one first sound pickup channel, and both ends of the first sound pickup channel are respectively connected to the first sound pickup port and the second sound pickup port, and the first channel and the second channel 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. For example, wind vortexes can enter through the first sound pickup port, part of the wind vortexes can enter the accommodating cavity through the second sound pickup channel, and part of the wind vortexes can flow out through the second sound pickup port, achieving the effect of diversion and pressure relief, which can further reduce the wind noise signal picked up by the microphone and further enhance the wind noise reduction effect. Accordingly, part of the wind vortexes entering through the second sound pickup port can flow out through the first sound pickup port, further enhancing the wind noise reduction effect.

[0019] In one possible implementation, a support portion is provided on the mounting wall, located between the mounting wall and the inner surface of the fairing. The support portion supports the fairing to reduce or avoid the risk of the fairing becoming dented during use, which could affect the appearance or even block the first sound pickup channel.

[0020] In one possible implementation, there are two first sound pickup channels, namely a third channel and a fourth channel. The ends of the third channel are connected to the first and second sound pickup ports, respectively, and the ends of the fourth channel are connected to the first and second sound pickup ports, respectively. The third channel is connected to the first channel, and the fourth channel is connected to the second channel. In other words, sound entering the third channel is transmitted through the first channel to the first microphone in the first chamber, and sound entering the fourth channel is transmitted through the second channel to the second microphone in the second chamber. The corresponding sound pickup channels of the first and second microphones are relatively independent, which helps improve the sound pickup effect of the first and second microphones, and thus helps improve the sound pickup effect of the entire device.

[0021] In addition, the third channel and the fourth channel share the first sound pickup port and the second sound pickup port. The connected first sound pickup port and the second sound pickup port can also form a pressure relief design, further improving the noise reduction effect, significantly reducing the impact of wind noise on the first microphone and the second microphone, and improving the sound pickup effect of the first microphone and the second microphone.

[0022] In one possible implementation, there are two first sound pickup channels, namely a third channel and a fourth channel. The first sound pickup port is connected to the third channel, the second sound pickup port is connected to the fourth channel, the third channel is connected to the first channel, and the fourth channel is connected to the second channel. Sound entering through the first sound pickup port, etc., can enter the first microphone in the first chamber after passing through the third channel and the first channel. Sound entering through the second sound pickup port, etc., can enter the second microphone in the second chamber after passing through the fourth channel and the second channel. This makes the corresponding sound pickup ports and pickup channels of the first and second microphones relatively independent, which can better improve the sound pickup effect of the first and second microphones.

[0023] In one possible implementation, a partition is provided on the mounting wall, located between the inner surface of the fairing and the mounting wall. The partition extends from a side adjacent to the first sound pickup opening to a side adjacent to the second sound pickup opening. The partition separates the gap between the inner surface of the fairing and the mounting wall to form two first sound pickup channels. Forming the partition on the mounting wall of the housing achieves two first sound pickup channels between the fairing and the housing, resulting in a simple and easy-to-implement structure.

[0024] In one possible implementation, the outer surface of the shell includes a top side and a bottom side, which are arranged relative to each other in a first direction. The outer surface of the shell also includes an inner side and an outer side, which are arranged relative to each other in a second direction. The second direction is perpendicular to the first direction. The inner side is used to fit with the user when the temples are worn, and a mounting wall is formed on the outer side.

[0025] In one possible implementation, the first and second sound pickup openings each have an elongated slit structure, and the first sound pickup channel is a slit-shaped channel. This allows the first sound pickup channel to have a long, flat slit structure, with a narrow slit width and a large surface area. This creates greater air resistance within the first sound pickup channel, further weakening the transmission of pulsating pressure from wind vortexes within the first sound pickup channel and optimizing the noise reduction effect. Furthermore, wind vortexes entering through the narrow first sound pickup opening and first sound pickup channel become laminar flow, further reducing the impact of wind noise on the microphone.

[0026] In a possible implementation, the widths of the first sound pickup channel, the first sound pickup port, and the second sound pickup port are respectively 0.5 mm, which has a smaller gap width and can better improve the noise reduction effect.

[0027] A second aspect of an embodiment of the present application provides glasses, comprising a frame and any of the above-described temples, wherein the temples are fixed to the frame, and the glasses are worn by the user via the frame and temples. By including the temples, the temples have excellent windproof and noise-reducing effects, effectively improving the noise reduction and sound pickup effects of the glasses, ensuring normal use of the glasses in windy conditions, and enhancing the user experience.

[0028] A third aspect of the present application provides a wearable device comprising a wearable device and any of the aforementioned temples, wherein the wearable device is configured to interact with the wearable device, the temples being secured to the wearable device, and the wearable device being worn by the user via the temples. By including the temples, the temples provide excellent windproof and noise-reduction properties, effectively enhancing the noise reduction and sound pickup properties of the wearable device, ensuring normal use of the wearable device in windy conditions and improving the user experience.

DETAILED DESCRIPTION

[0050] 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.

[0051] An embodiment of the present application provides a temple that can be used in a wearable electronic device, which can be a smart glass. The smart glasses can have an independent operating system and can be controlled by language or action to complete functions such as adding schedules, map navigation, interacting with friends, taking photos and videos, and talking with friends. It can also achieve wireless network access through a mobile communication network.

[0052] The glasses may include a frame and temples. A temple may be fixed on each side of the frame. The frame may be used to mount lenses. The lenses may be ordinary lenses through which users may observe scenes outside the glasses. Alternatively, the lenses may be lenses that can display images, etc. The lenses may present specific images, etc.

[0053] The glasses can be worn on the user's head via the temples. For example, the temples can be mounted on the user's ears, providing stable support for the temples through the ears, thereby achieving wearability. The frame can be mounted on the bridge of the user's nose to further ensure that the glasses are stably worn on the head.

[0054] The temples can be rotatably coupled to the frame. For example, the two temples can be rotatably coupled to the frame via hinges, shafts, or other structures, allowing the temples to be rotated relative to the frame and folded (e.g., the angle between the temples and the frame can be 0°), making it easier to store the glasses. When the glasses are to be worn, the temples can be rotated relative to the frame and unfolded (e.g., the angle between the temples and the frame can be 90°). The two temples can be clamped on the user's head, with the temples resting on the ears and the frame resting on the bridge of the nose.

[0055] Of course, in some other examples, the temples and the frame may not be limited to the form of rotational fit. For example, the temples and the frame may be fixedly assembled and the two cannot rotate relative to each other.

[0056] Alternatively, the wearable device may be an electronic device such as augmented reality (AR), virtual reality (VR), or mixed reality (MR), for example, VR glasses, AR glasses, MR glasses, etc. Of course, in some other examples, the wearable device is not limited to the form of glasses, and may be other types of wearable devices, such as other wearable devices adapted to the head.

[0057] Wearable devices may include wearable devices and temples. The wearable devices may be used to interact with users. For example, taking the wearable device as AR glasses, the wearable device may be an AR device that can superimpose virtual data on real-time images captured by the device and display them, thereby interacting with users.

[0058] Accordingly, a temple can be fixed on each side of the wearable device, and the wearable device can be worn on the user's head via the temple. The temple and the wearable device can be rotatably engaged, or the two can be fixedly assembled and cannot rotate relative to each other.

[0059] In the embodiments of the present application, the temples are described using smart glasses as an example.

[0060] FIG1 is a schematic structural diagram of a temple provided in an embodiment of the present application.

[0061] As shown in FIG1 , the temple 100 may include a shell 12 . The shell 12 may serve as the main load-bearing structural component of the glasses and may provide assembly space for multiple structural components of the glasses.

[0062] Exemplarily, the housing 12 may include a connecting end 102 and a wearing end 101. The connecting end 102 may be used to be fixed to the frame, and the wearing end 101 may be used to be mounted on the user's ear. For example, one side of the wearing end 101 may be recessed to form an arc-shaped structure to facilitate mounting on the ear.

[0063] In an embodiment of the present application, as shown in Figure 1, the shell 12 may include an inner side 102a, an outer side 102b, a top side 102c and a bottom side 102d (as shown in Figure 3), wherein the inner side 102a can be arranged opposite to the outer side 102b, and the top side 102c can be arranged opposite to the bottom side 102d.

[0064] For example, the top side 102c and the bottom side 102d are relative to each other in a first direction, such as the x-direction in Figure 1 , which direction can also be used as the thickness direction of the temple 100. The length direction of the temple 100 is a second direction, such as the y-direction in Figure 1 , and the wearing end 101 and the connecting end 102 of the shell 12 can be arranged relative to each other in the length direction. The outer side 102b and the inner side 102a are relative to each other in a third direction, such as the z-direction in Figure 1 , which direction can also be used as the width direction of the temple 100. When the glasses are worn, the inner side 102a of the shell 12 can fit the user's face (head), and the bottom side 102d can be the side of the shell 12 that is relatively close to the nose.

[0065] The temple 100 may also include a sound pickup port 15 for capturing ambient sound. The housing 12 may also include a cavity (see FIG. 3 ) within which a microphone may be mounted. The sound pickup port 15 may communicate with the sound hole of the microphone within the cavity, thereby allowing sound outside the temple 100 to be picked up by the sound pickup port 15 and transmitted to the microphone. The microphone can then convert audio signals into electronic signals, thereby enabling functions such as voice control and phone calls.

[0066] It is understood that the structures illustrated in the embodiments of the present application do not constitute specific limitations on the housing assembly. In other embodiments of the present application, the housing assembly may include more or fewer structural components than shown, or may combine or separate certain structural components, or may have different structural component arrangements.

[0067] For example, the electronic device may also include a speaker, and a sound outlet 103 may be provided on the shell 12 of the shell assembly (refer to Figure 1), and the accommodating cavity 14 may also be used to accommodate the speaker. The shell 12 may also have a sound outlet channel (not shown in the figure), and the speaker may be connected to the sound outlet 103 through the sound outlet channel. The speaker can realize the conversion between electronic signals and sound signals, and the generated sound can be transmitted through the sound outlet channel and the sound outlet 103, realizing functions such as call interaction and audio playback.

[0068] The electronic device may also include a circuit board. A data interface 104 may be provided on the shell 12 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, or the data interface 104 may also be used to connect the device to an external multimedia device, etc.

[0069] 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 a circuit board, a sensor, etc.

[0070] It is understandable that the effectiveness of language control, call functions, etc. is closely related to the sound pickup effect of the microphone and the 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 pickup port and microphone, forming a pulsating pressure applied to the microphone. The microphone will pick up wind noise signals, such as annoying noise or interference, 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.

[0071] Based on this, an embodiment of the present application provides a temple, which attenuates the wind noise signal entering the temple by setting a first sound pickup channel between the sound pickup port and the microphone, thereby reducing the impact of eddy currents on the microphone, and thereby effectively reducing the wind noise signal picked up by the microphone, thereby achieving the effect of reducing / preventing wind noise.

[0072] FIG2 is a schematic diagram of the disassembled structure of a temple provided in an embodiment of the present application.

[0073] 2 , the temple 100 may further include a fairing 13 , wherein the outer surface of the housing 12 may have a mounting wall 121 , for example, the mounting wall 121 may be located on the outer side surface 102 b of the housing 12 .

[0074] The fairing 13 may be disposed on the mounting wall 121 of the housing 12 , that is, the fairing 13 is disposed on the outer surface of the housing 12 , for example, the fairing covers a portion of the outer surface of the outer side surface 102 b .

[0075] FIG3 is a schematic diagram of the cross-sectional structure of the temple in FIG1 along the AA plane.

[0076] 3 , the side of the fairing 13 facing the mounting wall 121 is the inner surface 131 of the fairing 13 . A gap is formed between the inner surface 131 of the fairing 13 and the mounting wall 121 of the housing 12 to form the first sound pickup channel 11 .

[0077] The housing 12 has an interior containing a cavity 14. For example, the housing 12 may include a housing member 120a and a housing cover 120b. The housing cover 120b is disposed on the housing member 120a, and the housing and the housing cover 120b together form the accommodating cavity 14. The accommodating cavity 14 can be used to accommodate a microphone (see FIG. 4 ). A mounting wall 121 may be formed on the surface of the housing member 120a facing away from the housing cover 120b.

[0078] The first sound pickup channel 11 is connected to the accommodating cavity 14 in the housing 12. Specifically, the first sound pickup channel 11 can be connected to the sound hole of the microphone in the accommodating cavity 14. For example, as shown in Figures 2 and 3 , a second sound pickup channel 16 can be further provided on the mounting wall 121. The first sound pickup channel 11 and the second sound pickup channel 16 are connected, and the second sound pickup channel 16 is connected to the accommodating cavity 14, thereby achieving communication between the first sound pickup channel 11 and the accommodating cavity 14 through the second sound pickup channel 16.

[0079] Among them, the second sound pickup channel 16 can be a through hole, such as the second sound pickup channel 16 can be a through hole that passes through the shell part 120a, 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 14.

[0080] A first sound pickup port 151 and a second sound pickup port 152 may be provided on at least one of the fairing 13 and the outer shell 12. Taking the fairing 13 as an example, the first sound pickup port 151 and the second sound pickup port 152 are respectively connected to the first sound pickup channel 11, so that the first sound pickup port 151 and the second sound pickup port 152 can be respectively connected to the microphone in the accommodating cavity 14 through the first sound pickup channel 11.

[0081] Sounds from the outside of the temples can be picked up by the first sound pickup port 151 and the second sound pickup port 152 and transmitted to the microphone through the first sound pickup channel 11. Accordingly, after wind vortices are picked up by the first sound pickup port 151 and the second sound pickup port 152, they must pass through the first sound pickup channel 11 before being transmitted to the microphone. The provision of the first sound pickup channel 11 can attenuate wind noise signals entering the temples, thereby reducing wind noise, reducing the wind noise signals picked up by the microphone, and improving the microphone's sound pickup effect, ensuring the normal use of glasses and other devices in windy environments and enhancing the user experience.

[0082] In addition, by covering the outer surface of the shell 12 with a fairing 13, the first sound pickup channel 11 can be formed. The structural design is simple and easy to implement, and will not affect the structural design and layout inside the shell 12 of the temple. It is only necessary to cover the fairing 13 on the outer surface of the shell 12, which reduces the structural design and production difficulty of the temple, facilitates promotion and implementation, and can reduce the difficulty and cost of implementing wind noise protection design on the temple.

[0083] Among them, the first sound pickup port 151 and the second sound pickup port 152 can be respectively located on two opposite sides of the shell 12. For example, the first sound pickup port 151 and the second sound pickup port 152 can be located on two opposite sides of the shell 12 along the first direction, such as the first sound pickup port 151 can be located on the same side as the top side 10c of the shell 12, and the second sound pickup port 152 can be located on the same side as the bottom side 10d of the shell 12. This can reduce or avoid the user's head sweat and the like from entering the first sound pickup channel 11 and the microphone through the first sound pickup port 151 and the second sound pickup port 152 during the wearing and other use processes, and can better protect the microphone or other structural components in the accommodating cavity, thereby extending the service life of the device.

[0084] Continuing with FIG3 , the inner surface 131 of the fairing 13 can be surrounded by a groove structure 13a, and a protruding structure 12b can be raised on a partial area of ​​the mounting wall 121 of the outer shell 12. The protruding structure 12b and the groove structure 13a can cooperate with each other. When the fairing 13 is covered on the outer shell 12, the protruding structure 12b is accommodated in the groove structure 13a, and a gap is provided between the groove structure 13a and the protruding structure 12b to form a first sound pickup channel 11.

[0085] FIG4 is a schematic front view of the cross section of the temple along the AA plane in FIG1 .

[0086] It can be understood that, in combination with Figures 3 and 4, the protrusion structure 12b is formed by a curved protrusion on the mounting wall 121 of the shell 12, and the groove structure 13a is formed by a curved depression on the inner surface 131 of the fairing 13. Therefore, the first sound pickup channel 11 located between the protrusion structure 12b and the groove structure 13a can be designed with a curved structure. That is, the first sound pickup channel 11 is a curved channel that bends and extends, rather than a flat channel that extends horizontally. It can extend the length of the first sound pickup channel 11 and extend the path length of the wind vortex from the first sound pickup port 151 and / or the second sound pickup port 152 to the accommodating cavity 14. It can effectively weaken the transmission of the pulsating pressure formed by the wind vortex in the first sound pickup channel 11, reduce the influence of wind noise on the microphone, achieve the effect of attenuating wind noise, further reduce the wind noise signal picked up by the microphone, and is more conducive to improving the wind noise reduction effect, ensuring the normal use of the glasses in windy scenes.

[0087] Exemplarily, the first sound pickup channel may include at least one bending section. The bending section means that the portion of the channel is bent rather than straight. It can be understood as a straight channel being bent to form a certain bending angle. For example, the portion of the channel may be a curved arc channel. As shown in the cross-section of the first sound pickup channel 11 in Figure 4, the first bending section 101 may be arc-shaped.

[0088] It is understandable that the specific bending angle and bending shape of the bending section can be selected and set according to actual needs. For example, the bending section can be a right-angle bend, a trapezoidal bend, etc.

[0089] The bend section can be located between at least one of the first and second sound pickup openings and the second sound pickup channel, and at least one of the first and second sound pickup openings is connected to the second sound pickup channel via the bend section. In other words, as the wind vortex flows from the first and second sound pickup openings into the second sound pickup channel (microphone), it passes through at least one bend section, effectively extending the transmission path of the wind vortex, ensuring that the pulsating pressure generated by the wind vortex is reduced while being transmitted within the first sound pickup channel, thereby achieving a better wind noise attenuation effect.

[0090] For example, referring to Figure 3, taking the first sound pickup channel 11 including two bending sections, namely the first bending section 101 and the second bending section 102 as an example, the first bending section 101 can be located between the first sound pickup port 151 and the second sound pickup channel 16, and the second bending section 102 can be located between the second sound pickup port 152 and the second sound pickup channel 16.

[0091] 4 , the first sound pickup channel 11 may include a first transverse section 111, a vertical section 112, and a second transverse section 113 connected in sequence, wherein the first bend section 101 may be located between the first transverse section 111 and the vertical section 112, and the first transverse section 111 and the vertical section 112 may be connected via the first bend section 101. The second bend section 102 may be located between the second transverse section 113 and the vertical section 112, and the second transverse section 113 and the vertical section 112 may be connected via the second bend section 102.

[0092] The vertical section 112 can communicate with the second sound pickup channel 16, the first sound pickup port 151 can communicate with the first transverse section 111, and the second sound pickup port 152 can communicate with the second transverse section 113. In other words, there is a first bend section 101 between the first sound pickup port 151 and the second sound pickup channel 16, and a second bend section 102 between the second sound pickup port 152 and the second sound pickup channel 16. This ensures that wind entering from both the first sound pickup port 151 and the second sound pickup port 152 must flow through a bend section before entering the second sound pickup channel. This can better weaken the transmission of pulsating pressure generated by wind vortices within the first sound pickup channel 11, ensuring that wind noise has a minimal impact on the microphone 200. Furthermore, the structural design is relatively simple, making it easy to manufacture and implement.

[0093] For example, the cross-section of the first sound pickup channel 11 (a cross-section taken along plane AA in FIG. 1 ) can be a U-shaped shape as shown in FIG. 4 , which has a relatively large number of bends, thereby further improving the wind noise reduction effect. Of course, in other examples, the cross-section of the first sound pickup channel 11 can also be a C-shaped, arc-shaped, or other regular or irregular shapes.

[0094] Taking the first sound pickup port 151 as an example, the wind vortex entering from the first sound pickup port 151 needs to flow through the first transverse section 111, the first bending section 101, the vertical section 112, and the second sound pickup channel 16 before entering the microphone 200 in the accommodating cavity 14. The transmission through the long curved path weakens the impact of the wind vortex on the microphone 200, thereby reducing the wind noise signal picked up by the microphone 200.

[0095] Accordingly, the wind vortex entering from the second sound pickup port 152 needs to flow through the second transverse section 113, the second bending section 102, the vertical section 112, and the second sound pickup channel 16 before entering the microphone 200 in the accommodating cavity 14, thereby reducing the wind noise signal picked up by the microphone 200.

[0096] It can be understood that the fairing 13 is arranged on the installation wall 121, and a second sound pickup channel 16 is opened on the installation wall 121. There is a accommodating chamber 14 at a position corresponding to the installation wall 121 in the outer shell 12. The accommodating chamber 14 is located on the side of the installation wall 121 facing away from the fairing 13. In this way, a bending area will be formed at the position connecting the vertical section 112 to the second sound pickup channel 16, which can further increase the path of wind noise from the sound pickup port to the microphone 200, weaken the transmission of the pulsating pressure of the eddy current in the first sound pickup channel 11 and the second sound pickup channel 16, thereby further reducing the influence of wind noise and achieving a better wind noise reduction effect.

[0097] For example, the center line of the second sound pickup channel 16 may be perpendicular to the vertical section 112 , which can better reduce the influence of wind noise and achieve a better wind noise reduction effect.

[0098] Continuing with FIG4 , the extension direction of the first sound pickup port 151 can intersect with the extension direction of the first transverse section 111, and the extension direction of the second sound pickup port 152 can intersect with the extension direction of the second transverse section 113. The extension direction can be the direction in which the wind flows. This creates a bending area at the location where the first sound pickup port 151 and the first transverse section 111 are connected, and a bending area at the location where the second sound pickup port 152 and the second transverse section 113 are connected. This can further increase the path of wind noise from the first sound pickup port 151 and the second sound pickup port 152 to the microphone 200, weaken the transmission of the pulsating pressure of the eddy current in the first sound pickup channel 11, further reduce the impact of wind noise, achieve a more excellent wind noise reduction effect, and significantly improve the sound pickup effect of the microphone 200.

[0099] For example, as shown in Figure 4, the extension direction of the first sound pickup port 151 and the extension direction of the second sound pickup port 152 can be consistent with the first direction (x direction), the extension direction of the first transverse segment 111 and the extension direction of the second transverse segment 113 can be consistent with the third direction (z direction), the extension direction of the first sound pickup port 151 is perpendicular to the extension direction of the first transverse segment 111, and the extension direction of the second sound pickup port 152 is perpendicular to the extension direction of the second transverse segment 113.

[0100] 4 , a first sound pickup channel 11 is formed between the inner surface 131 of the fairing 13 and the mounting wall 121 of the housing 12 . The width (gap width) of the first sound pickup channel 11 may refer to the vertical distance between the inner surface 131 and the mounting wall 121 .

[0101] A first sound pickup port 151 and a second sound pickup port 152 are provided on the fairing 13. The width of the first sound pickup port 151 and the second sound pickup port 152 refers to the opening width. For example, taking the example of forming the first sound pickup port 151 by opening a notch on the side wall edge of the fairing 13, the depth of the notch is the width of the first sound pickup port. The fairing 13 is fixed on the outer shell 12, and the side wall edge of the fairing 13 is in contact with the mounting wall 121. The distance between the bottom surface of the first sound pickup port 151 (the side opposite to the mounting wall) and the mounting wall 121 is the width of the first sound pickup port, as shown by h in Figure 4.

[0102] It is understandable that the length of the temple shell 12 is relatively long (length along the second direction), and the length of the first sound pickup port 151, the second sound pickup port 152 and the first sound pickup channel 11 opened on the fairing 13 or the shell 12 along the second direction can also be longer.

[0103] FIG5 is an enlarged schematic diagram of a temple at the first sound pickup port provided in an embodiment of the present application.

[0104] 5 , 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 correspondingly, the second sound pickup opening may also be a long strip-shaped slot structure.

[0105] As shown in FIG4 , the first sound pickup channel 11 can be a slit-shaped channel with a relatively narrow slit width, allowing the first sound pickup channel 11 to have a flat and elongated slit structure. This allows the first sound pickup channel 11 to have a relatively small slit width and a relatively large area. This creates greater air resistance within the first sound pickup channel 11, further weakening the transmission of pulsating pressure from wind vortexes within the first sound pickup channel 11 and optimizing the noise reduction effect. Furthermore, the wind vortexes entering through the narrow first sound pickup opening 151, the second sound pickup opening 152, and the first sound pickup channel 11 become laminar flow, further reducing the impact of wind noise on the microphone.

[0106] For example, the slit width of the first sound pickup port 151 , the slit width of the second sound pickup port 152 , and the slit width of the first sound pickup channel 11 may be equal to facilitate assembly.

[0107] For example, the gap width of the first sound pickup port 151 , the gap width of the second sound pickup port 152 , and the gap width of the first sound pickup channel 11 may all be 0.5 mm. A smaller gap width can better improve the noise reduction effect.

[0108] The length of the first sound pickup channel 11 along the first direction may be greater than or equal to the length of the first sound pickup opening 151 or the second sound pickup opening 152 in the first direction, ensuring that the first sound pickup channel 11 has a relatively large area.

[0109] FIG. 6 is a schematic structural diagram of a fairing provided by an embodiment of the present application.

[0110] Referring to FIG. 6, the fairing 13 may include a first side wall 132, a second side wall 133, and a third side wall 134. The first side wall 132 and the third side wall 134 may be located at both ends of the second side wall 133, and the first side wall 132 and the third side wall 134 may be arranged oppositely. For example, the first side wall 132 and the third side wall 134 may be arranged oppositely along a first direction, making the shape of the fairing 13 similar to a C shape or a U shape.

[0111] The inner surfaces of the first side wall 132, the second side wall 133, and the third side wall 134 may enclose a groove structure 13a. The structure is simple and facilitates 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 fairing. Among them, the inner surface of the first side wall 132 and the inner surface of the third side wall 134 are opposite, and the inner surface of the second side wall 133 is respectively connected to the inner surface of the first side wall 132 and the inner surface of the third side wall 134.

[0112] The first sound pickup port 151 and the second sound pickup port 152 may be opened on the fairing 13. For example, an opening may be formed on one end of the first side wall 132 facing away from the second side wall 133 to form the first sound pickup port 151, and the first sound pickup port 151 may be a notch formed on the edge of one end of the first side wall 132 facing away from the second side wall 133.

[0113] An opening may be formed on one end of the third side wall 134 facing away from the second side wall 133 to form the second sound pickup port 152, and the second sound pickup port 152 may also be a notch formed on the edge of one end of the third side wall 134 facing away from the second side wall 133.

[0114] Of course, in some other examples, the first sound pickup port 151 may be a through hole on one end of the first side wall 132 facing away from the second side wall 133, and the through hole may not extend through the edge of one end of the first side wall 132 facing away from the second side wall 133. The second sound pickup port 152 may also not extend through the edge of one end of the third side wall 134 facing away from the second side wall 133.

[0115] The sound pickup ports are opened on the fairing 13, and there is no need to open an opening on the outer shell 12 to form a sound pickup port, which further reduces the impact on the structural layout of the outer shell 12 and is beneficial to protecting the various structural devices in the accommodation cavity of the outer shell 12.

[0116] Of course, in some examples, the first sound pickup port 151 and the second sound pickup port 152 may also be opened on the outer shell 12. Or, in some examples, one sound pickup port may be opened on one of the fairing 13 and the outer shell 12, and the other sound pickup port may be opened on the other one.

[0117] Alternatively, in some examples, openings may be respectively provided on the outer shell and the fairing. For example, an opening may be provided on the end of the first side wall of the fairing 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 mounting wall surface of the outer shell at a position corresponding to the first side wall. When the fairing cover is provided on the outer shell, the opening on the fairing and the opening on the outer shell are opposite to each other and together form a sound pickup port.

[0118] FIG7 is a schematic diagram of a partial structure of a housing provided in an embodiment of the present application.

[0119] In order to improve the assembly integration between the fairing and the shell, as shown in Figure 7, a coordination groove 12a can be opened on the outer surface of the shell 12, and the protruding structure 12b can be formed by a protrusion 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 12, and the fairing 13 can be accommodated in the coordination groove 12a (as shown in combination with Figure 9), so that the fairing and the shell 12 have a higher assembly integration, which is beneficial to improving the aesthetics of the temples.

[0120] An assembly groove may also be provided on the mounting wall surface of the housing 12, such as an assembly groove 125 on the raised 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.

[0121] A raised fixing portion 124 may also be provided on the raised structure 12b. The fixing portion 124 may be located at both ends of the raised structure 12b along the second direction. The fixing portion 124 may be used to support the fairing and achieve a fixed connection with the fairing.

[0122] FIG8 is a schematic diagram of a partial cross-sectional structure of the temple along the BB plane in FIG1 .

[0123] For example, as shown in FIG8 , an adhesive layer (not shown) can be formed on the fixing portion 124. The fairing 13 is placed on the outer shell 12, and the fixing portion 124 is supported between the fairing 13 and the outer shell 12 to ensure that the first sound pickup channel 11 is formed between the fairing 13 and the outer shell 12. Furthermore, the fairing 13 can be bonded to the fixing portion 124 via the adhesive layer, ensuring a secure bond between the fairing 13 and the outer shell 12.

[0124] Continuing with Figures 7 and 8, a support portion 122 may be further provided on the mounting wall surface (such as the raised structure 12b) of the housing 12. Referring to Figure 8, the fairing 13 is covered on the housing 12, and the support portion 122 may be located between the fairing 13 and the housing 12. The support portion 122 serves to support the fairing 13. In particular, when a first sound pickup channel 11 with a larger area is formed between the fairing 13 and the housing 12, the support portion 122 can provide good support for the fairing 13, thereby reducing or avoiding the problem of the fairing 13 being dented during use, which may affect the appearance or even block the first sound pickup channel 11.

[0125] 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 receiving sound, which can better improve the sound pickup effect and enable the device to have better sound pickup performance.

[0126] Exemplarily, when there are two microphones, as shown in Figure 8, the accommodating cavity 14 can have two chambers, such as a first chamber 141 and a second chamber 142. The first chamber 141 can be used to accommodate the first microphone, and the second chamber 142 can be used to accommodate the second microphone. The first chamber 141 and the second chamber 142 can be distributed along the second direction, the first chamber 141 can be set closer to the connecting end of the shell 12, and the second chamber 142 can be set closer to the wearing end of the shell 12.

[0127] There may also be two second sound pickup channels, such as a first channel 16a and a second channel 16b. The first channel 16a may communicate with the first chamber 141, and the second channel 16b may communicate with the second chamber 142. The first sound pickup channel 11 may communicate with the first channel 16a and the second channel 16b, respectively, thereby enabling the first sound pickup channel 11 to communicate with the first microphone in the first chamber 141 and the second microphone in the second chamber 142, respectively.

[0128] FIG9 is another schematic cross-sectional structure diagram of a temple provided in an embodiment of the present application.

[0129] In order to further enhance the wind noise reduction effect and sound pickup effect, in a possible example, continuing with Figures 8 and 9, the first sound pickup channel 11 can be one, that is, the fairing 13 is covered on the outer shell 12, and the gap between the inner surface 131 of the fairing 13 and the mounting wall 121 of the outer shell 12 forms a first sound pickup channel 11 as a whole.

[0130] The two ends of the first sound pickup channel 11 are respectively connected to the first sound pickup port 151 and the second sound pickup port 152, and the first sound pickup channel 11 is connected to the second sound pickup channel 16, such as being connected to the first channel 16a and the second channel 16b respectively (as shown in Figure 8). The connected first sound pickup port 151 and the second sound pickup port 152 can form a pressure relief design to reduce the impact of wind noise on the microphone 200.

[0131] Specifically, as shown in FIG9 , the wind vortex can enter through the first sound pickup port 151, and part of the wind vortex can enter the accommodating chamber 14 through the second sound pickup channel 16, such as entering the first chamber through the first channel and entering the second chamber through the second channel. Part of the wind vortex can flow out through the second sound pickup port 152, achieving a pressure relief effect, further reducing the wind noise signal picked up by the microphone 200, and further improving the wind noise reduction effect. Accordingly, part of the wind vortex that enters through the second sound pickup port 152 can flow out through the first sound pickup port 151, further improving the wind noise reduction effect.

[0132] In particular, along the direction in which the first channel 16a and the second channel 16b are distributed (i.e., the second direction), the first sound pickup channel 11 can be divided into an area corresponding to the first channel 16a and an area corresponding to the second channel 16b (as shown in FIG8 ). For example, with the support portion 122 as the center line, the first sound pickup channel 11 can be divided into two areas, one of which corresponds to the position of the first channel 16a, and the other corresponds to the position of the second channel 16b. The first sound pickup port is located at one end of the area corresponding to the first channel and the area corresponding to the second channel. The first sound pickup port can overlap with the area corresponding to the first channel and the area corresponding to the second channel, respectively. For example, the first sound pickup port can extend along the second direction from the area corresponding to the first channel to the area corresponding to the second channel, so that the sound entering from the first sound pickup port, after passing through the first pickup channel, enters the first microphone in the first chamber through the first sound channel and the second microphone in the second chamber through the second sound channel.

[0133] Correspondingly, the second sound pickup port is located at the other end of the area corresponding to the first channel and the area corresponding to the second channel. The second sound pickup port can overlap with the area corresponding to the first channel and the area corresponding to the second channel respectively. For example, the second sound pickup port can also extend along the second direction from the area corresponding to the first channel to the area corresponding to the second channel, so that the sound entering from the second sound pickup port passes through the first sound pickup channel and enters the first microphone in the first chamber through the first channel and the second microphone in the second chamber through the second channel.

[0134] Alternatively, the first sound pickup port may overlap only with the area corresponding to the first channel, such as the first sound pickup port is located at one end of the area corresponding to the first channel and does not extend to the area corresponding to the second channel. The second sound pickup port may also overlap only with the area corresponding to the second channel, such as the second sound pickup port is located at the other end of the area corresponding to the second channel and does not extend to the area corresponding to the first channel. Most of the sound entering through the first sound pickup port enters the first microphone in the first chamber through the first channel, and most of the sound entering through the second sound pickup port enters the second microphone in the second chamber through the second channel, which helps to improve the overall sound pickup effect of the device.

[0135] It is understood that there can be only one fairing 13, which is mounted on the housing 12 to form a first sound pickup channel 11 between the fairing 13 and the housing 12. Alternatively, there can be two fairings 13, which can be mounted side by side on the housing 12 to form a first sound pickup channel with the housing 12.

[0136] FIG10 is a comparison diagram of the wind noise signal frequency response of a temple provided by an embodiment of the present application. Curves S11 and S12 in FIG10 are the wind noise signal frequency response curves of the first microphone and the second microphone in the temple provided by the embodiment of the present application, respectively, in a scenario with a wind noise energy of 5 m / s. Curves S21 and S22 are the wind noise signal frequency response curves of the first microphone and the second microphone in the temple of the comparison group, respectively, in a scenario with a wind noise energy of 5 m / s. For example, the temple in the comparison group includes a housing, a sound pickup hole is provided on the top or bottom side of the housing, a sound pickup channel is provided within the housing, the sound pickup hole is connected to the first microphone and the second microphone through the sound pickup channel, and the sound pickup channel is a straight channel (without a bend).

[0137] As shown in FIG10 , compared with the control group, the wind noise signals of the first microphone and the second microphone in the temple provided by the embodiment of the present application are reduced by a maximum of 9 dB at 100 Hz and by 2 dB at 1 kHz.

[0138] Table 1 shows the comparison of wind noise energy gains between the first microphone and the second microphone in the 100kHz-8kHz frequency band at 5m / s and 10m / s.

[0139] Combining Figure 10 and Table 1, it can be seen that the temples provided by the embodiment of the present application have a more excellent wind noise reduction effect. The wind noise gain of the first microphone and the second microphone in the temples provided by the embodiment of the present application is 7dB to 9dB, and the wind noise is reduced to 8m / s.

[0140] FIG11 is a schematic diagram of the structure of another temple provided in an embodiment of the present application, and FIG12 is a schematic diagram of the disassembled structure of another temple provided in an embodiment of the present application.

[0141] In another possible example, the housing can accommodate a first microphone and a second microphone, and the housing can have two first sound pickup channels. Referring to FIG11 , a fairing 13 is provided on the outer surface of the housing 12 . The specific structures of the fairing 13 and the housing 12 can be found in the foregoing description.

[0142] As shown in FIG12 , two second sound pickup channels may be provided on the mounting wall surface of the housing 12 , namely a first channel 16 a and a second channel 16 b , and the gap between the inner surface of the fairing 13 and the mounting wall surface of the housing 12 may form two independent first sound pickup channels.

[0143] FIG13 is a partially enlarged schematic diagram of a housing in a temple provided in an embodiment of the present application.

[0144] Specifically, as shown in Figures 12 and 13 , a partition 123 can be provided on the mounting wall of the housing 12, such as a raised partition 123 on the outer wall of the raised structure 12b (the side facing the fairing 13). The partition 123 can extend from the side of the raised structure 12b adjacent to the first sound pickup port to the side adjacent to the second sound pickup port. The partition 123 can be located between one end of the first channel 16a on the mounting wall (on the outer wall of the raised structure 12b) and one end of the second channel 16b on the mounting wall (on the outer wall of the raised structure 12b).

[0145] FIG14 is a schematic diagram of a partial cross-sectional structure of the temple in FIG11 at plane BB.

[0146] As shown in Figure 14, the partition 123 is located between the mounting wall 121 of the outer shell 12 and the inner surface 131 of the fairing 13, so that the partition 123 can divide the gap between the mounting wall 121 and the inner surface 131 into two parts to form two relatively independent first sound pickup channels, such as the third channel 11a and the fourth channel 11b.

[0147] The two first sound pickup channels may be communicated with the two second sound pickup channels respectively. For example, the third channel 11 a may be communicated with the first channel 16 a , and the fourth channel 11 b may be communicated with the second channel 16 b .

[0148] That is to say, the sound entering the third channel 11a is transmitted to the first microphone in the first chamber 141 through the first channel 16a, and the sound entering the fourth channel 11b is transmitted to the second microphone in the second chamber 142 through the second channel 16b. The sound pickup channels corresponding to the first microphone and the second microphone are relatively independent, which is beneficial to improving the sound pickup effect of the first microphone and the second microphone, and thus beneficial to improving the sound pickup effect of the entire device.

[0149] In some examples, both of the two first sound pickup channels may be connected to the first sound pickup port and the second sound pickup port, that is, the third channel 11 a and the fourth channel 11 b may share the first sound pickup port and the second sound pickup port.

[0150] FIG15 is a schematic diagram of a partial cross-sectional structure of the temple in FIG11 at the CC plane, and FIG16 is a schematic diagram of a partial cross-sectional structure of the temple in FIG11 at the AA plane.

[0151] As shown in Figure 15, the first sound pickup port 151 and the second sound pickup port 152 are respectively connected to the third channel 11a. The sound entering from the first sound pickup port 151 and the second sound pickup port 152 can be transmitted to the third channel 11a and transmitted to the first microphone in the first chamber 141 through the first channel 16a. The curved and elongated third channel 11a has a good noise reduction effect, and the connected first sound pickup port 151 and the second sound pickup port 152 can also form a pressure relief design, further improving the noise reduction effect, significantly reducing the influence of wind noise on the first microphone, and improving the sound pickup effect of the first microphone.

[0152] Correspondingly, as shown in Figure 16, the first sound pickup port 151 and the second sound pickup port 152 are respectively connected to the fourth channel 11b. The sound entering from the first sound pickup port 151 and the second sound pickup port 152 can be transmitted to the fourth channel 11b and transmitted to the second microphone in the second chamber 142 through the second channel 16b. The curved and elongated fourth channel 11b has a good noise reduction effect, and the connected first sound pickup port 151 and the second sound pickup port 152 can also form a pressure relief design, which further enhances the noise reduction effect, significantly reduces the influence of wind noise on the second microphone, and enhances the sound pickup effect of the second microphone.

[0153] Exemplarily, the first sound pickup port 151 is located at one end of the third channel 11a and the fourth channel 11b, and the first sound pickup port 151 can overlap with the third channel 11a and the fourth channel 11b respectively. For example, the first sound pickup port 151 can extend from the third channel 11a to the fourth channel 11b along the second direction.

[0154] Accordingly, the second sound pickup opening 152 is located at the other end of the third channel 11a and the fourth channel 11b. The second sound pickup opening 152 can overlap with the third channel 11a and the fourth channel 11b, respectively. For example, the second sound pickup opening 152 can extend from the third channel 11a to the fourth channel 11b along the second direction. This facilitates the connection between the first sound pickup opening 151 and the third channel 11a and the fourth channel 11b, and the connection between the second sound pickup opening 152 and the third channel 11a and the fourth channel 11b, respectively. It also ensures that the first sound pickup opening 151 and the second sound pickup opening 152 have a longer length, which is conducive to improving the noise reduction effect.

[0155] It can be understood that in this example, the number of fairings 13 can be one, and one fairing 13 is covered on the installation wall of the shell 12 with a partition, so that two first sound pickup channels are formed between the inner surface of the fairing 13 and the installation wall of the shell 12.

[0156] Alternatively, there may be two fairings 13, which are respectively covered on the mounting wall surface of the outer shell 12 having a partition, wherein a third channel 11a is formed between the inner surface of one fairing 13 and a portion of the mounting wall surface of the outer shell 12, and a fourth channel 11b is formed between the inner surface of the other fairing 13 and another portion of the mounting wall surface of the outer shell 12.

[0157] Alternatively, in some examples, one of the two first sound pickup channels may be in communication with the first sound pickup port, and the other one of the two first sound pickup channels may be in communication with the second sound pickup port.

[0158] FIG17 is a schematic structural diagram of another type of temple provided in an embodiment of the present application, and FIG18 is an enlarged view of a partial structure of the temple in FIG17 .

[0159] 17 and 18 , taking the second sound pickup port 152 as an example, the second sound pickup port 152 may be located only at one end of the fourth channel (not shown in the figure) and may not extend to the third channel. The second sound pickup port 152 only overlaps with the fourth channel and is in communication with the fourth channel.

[0160] Accordingly, the first sound pickup port can be located only at one end of the third channel and not extend to the fourth channel. The first sound pickup port is connected to the third channel and only overlaps with the third channel. In other words, making the corresponding sound pickup ports and sound pickup channels of the first and second microphones relatively independent can better improve the sound pickup effect of the first and second microphones.

[0161] FIG19 is a partial schematic diagram of the cross-sectional structure of the temple in FIG17 at the CC plane.

[0162] As shown in Figure 19, the first sound pickup port 151 is connected to the third channel 11a. The sound entering from the first sound pickup port 151 can enter the first microphone in the first chamber 141 after passing through the third channel 11a and the first channel 16a. The curved and elongated third channel 11a can achieve a good noise reduction effect, thereby achieving the purpose of reducing the wind noise signal of the first microphone.

[0163] FIG20 is a partial schematic diagram of the cross-sectional structure of the temple in FIG17 at plane AA.

[0164] As shown in Figure 20, the second sound pickup port 152 is connected to the fourth channel 11b. The sound entering from the second sound pickup port 152 can enter the second microphone in the second chamber 142 after passing through the fourth channel 11b and the second channel 16b. The curved and elongated fourth channel 11b can achieve a good noise reduction effect, thereby achieving the purpose of reducing the wind noise signal of the second microphone.

[0165] Accordingly, in this example, there may be one fairing 13, which is disposed on the housing 12 having the partition 123, so that the third passage 11a and the fourth passage 11b are formed between the fairing 13 and the housing 12. Alternatively, there may be two fairings 13, each disposed on the housing 12, with the third passage 11a formed between one fairing 13 and the housing 12, and the fourth passage 11b formed between the other fairing 13 and the housing 12.
