[0001] The present application relates to the field of acoustic technology such as headphones, hearing aids, and communications, and in particular to an anti-wind noise component and a sound pickup device. Background Art

[0002] In the field of acoustics, wind noise in headphones is the sound produced by the friction between airflow and the housing, which generates vibrations. This sound is picked up by the microphone, amplified, and transmitted to the ear canal. Conventional technology typically designs the housing near the microphone to have a smooth surface to prevent friction with the airflow. However, this solution is only moderately effective in reducing wind noise and cannot handle strong winds. Summary of the Invention

[0031] As shown in FIG1 and FIG2 , the first embodiment of the present application discloses an anti-wind noise assembly 1, which is applicable to a pickup 2. The anti-wind noise assembly 1 includes a first elastic member 11 and a fixing member 12, as follows:

[0032] As shown in Figures 3 and 4 , along the axial direction A of the first elastic member 11, a pickup cavity 111 and a receiving cavity 112 are defined within the first elastic member 11, which are vertically offset and interconnected. The pickup cavity 111 and the receiving cavity 112 are each connected to the outside world. The receiving cavity 112 is used to accommodate an external microphone 2, which picks up sound through the pickup cavity 111. The pickup hole 21 of the microphone 2 is connected to the pickup cavity 111. Because the microphone 2 is encased by the first elastic member 11, the microphone 2 contacts the outside world (e.g., the earphone housing 3 or a circuit board) through the first elastic member 11. This reduces the transmission of vibrations, effectively reducing wind noise even in strong winds.

[0033] In some embodiments, the pickup 2 is a microphone, the first elastic member 11 is a soft colloid, such as silicone or rubber, and the outer surface of the first elastic member 11 is cylindrical, square or other irregular shapes. The shape here is only an example and is not limited. It can also be other shapes.

[0034] To further reduce vibration transmission, the anti-wind noise assembly 1 further includes a second elastic member (not shown), which is wrapped around the outer wall of the first elastic member 11 corresponding to the accommodating cavity 112. In some embodiments, the second elastic member is a sponge and can be wrapped by bonding, interference fit, or wire binding. The wrapping methods described here are merely examples and are not limiting; other methods are also possible.

[0035] In this embodiment, as shown in FIG4 , both the accommodating cavity 112 and the sound pickup cavity 111 extend along the axial direction A of the first elastic member 11. The openings of the accommodating cavity 112 and the sound pickup cavity 111, which communicate with the outside world, are also oriented along the axial direction A of the first elastic member 11. The connection between the sound pickup cavity 111 and the accommodating cavity 112 is oriented along the radial direction B of the first elastic member 11. In some embodiments, the accommodating cavity 112 is square, which can be modified to suit the shape of the pickup 2, while the sound pickup cavity 111 is cylindrical or square, etc. These shapes are merely examples and are not limiting; other shapes are also possible.

[0036] In this embodiment, as shown in FIG2 and FIG4 , the fixing member 12 is an integral structure with the outer side wall of the first elastic member 11 corresponding to the sound pickup cavity 111 , and the fixing member 12 is used to be fixed on an external fixture (eg, the earphone housing 3 , etc.).

[0037] Specifically, the fixing member 12 is a shell that extends outward from the opening of the sound pickup cavity 111 connected to the outside and covers the first elastic member 11. As shown in Figure 1, the shell is mounted on the earphone shell 3, and the first elastic member 11 is inserted into the hole 31 of the earphone shell 3.

[0038] In order to prevent dust from entering the sound pickup cavity 111, a mounting slot 121 for mounting a dustproof member is provided on the shell at the opening of the sound pickup cavity 111. In some embodiments, the dustproof member is a dustproof net.

[0039] As shown in FIG5 , the second embodiment of the present application discloses an anti-wind noise assembly 1 suitable for a pickup 2 . The anti-wind noise assembly 1 includes a first elastic member 11 and a fixing member 12 , as follows:

[0040] As shown in Figures 6 and 7 , along the axial direction A of the first elastic member 11, a pickup cavity 111 and a receiving cavity 112 are formed within the first elastic member 11, which are vertically offset and interconnected. The pickup cavity 111 and the receiving cavity 112 are each connected to the outside world. The receiving cavity 112 is used to accommodate an external microphone 2 and pick up sound through the pickup cavity 111. The pickup hole 21 of the microphone 2 is connected to the pickup cavity 111. Because the microphone 2 is encased by the first elastic member 11, the microphone 2 contacts the outside world (e.g., the earphone housing 3 or a circuit board) through the first elastic member 11. This reduces the transmission of vibrations, effectively reducing wind noise even in strong winds.

[0041] In some embodiments, the pickup 2 is a microphone, the first elastic member 11 is a soft colloid, such as silicone or rubber, and the outer surface of the first elastic member 11 corresponding to the accommodating cavity 112 is square, and the outer surface of the first elastic member 11 corresponding to the pickup cavity 111 is columnar. It can be understood that other shapes may also be used in other embodiments, which is not limited here.

[0042] To further reduce vibration transmission, the anti-wind noise assembly 1 further includes a second elastic member (not shown), which is wrapped around the outer wall of the first elastic member 11 corresponding to the accommodating cavity 112. In some embodiments, the second elastic member is a sponge and can be wrapped by bonding, interference fit, or wire binding. The wrapping methods described here are merely examples and are not limiting; other methods are also possible.

[0043] In this embodiment, as shown in FIG4 , both the accommodating cavity 112 and the sound pickup cavity 111 extend along the axial direction A of the first elastic member 11. The openings of the accommodating cavity 112 and the sound pickup cavity 111, which communicate with the outside world, are also oriented along the axial direction A of the first elastic member 11. The connection between the sound pickup cavity 111 and the accommodating cavity 112 is oriented along the radial direction B of the first elastic member 11. In some embodiments, the accommodating cavity 112 is square, which can be modified to suit the shape of the pickup 2, while the sound pickup cavity 111 is cylindrical or square, etc. These shapes are merely examples and are not limiting; other shapes are also possible.

[0044] In this embodiment, the fixing member 12 and the outer side wall of the first elastic member 11 corresponding to the sound pickup cavity 111 are an integral structure, and the fixing member 12 is used to be fixed on an external fixture (such as the earphone housing 3, etc.).

[0045] Specifically, the fixing member 12 is a clamping portion provided on the outer side wall of the first elastic member 11 corresponding to the sound pickup cavity 111. The clamping portion includes at least one raised rib spaced apart from each other, which can be clamped to the hole 31 of the earphone housing 3 through the raised rib. It is understood that in other embodiments, the number of raised ribs may be at least two, three, four, or any other number.

[0046] As shown in Figure 3, the third embodiment of the present application discloses a sound pickup device comprising a sound pickup 2 and the anti-wind noise assembly 1 described in the first or second embodiment above, which will not be described in detail here. The sound pickup 2 is tightly fitted into the accommodating cavity 112, and the sound pickup hole 21 of the sound pickup 2 is connected to the sound pickup cavity 111. In some embodiments, the sound pickup hole 21 faces toward or away from the sound pickup cavity 111, preferably facing directly toward the sound pickup cavity 111.

[0047] By implementing this application, the following beneficial effects are achieved:

[0048] The present application provides an anti-wind noise component for the pickup. Since the pickup is wrapped by the first elastic member, the contact between the pickup and the outside is through the first elastic member. The first elastic member can reduce the transmission of vibration, thereby effectively reducing wind noise and improving user experience.
