[0009] As a preferred embodiment of the present invention, the edge of the non-return ring is provided with a non-return flange.
[0010] Compared with the prior art, the present invention has the following beneficial effects:
[0011] The utility model provides a microphone assembly with a foam structure. Because the clamping ribs gradually converge toward the top of the noise-canceling sleeve, the assembly automatically adapts to the outer diameter of the microphone body, making it suitable for installation of microphone bodies of varying outer diameters. Furthermore, the anti-slip protrusions effectively prevent the microphone body from slipping out of the noise-canceling sleeve. Because the microphone body is located within the noise-canceling sleeve, the sleeve provides vibration reduction and sound insulation. The sleeve effectively absorbs and attenuates mechanical vibrations, reducing their interference with sound pickup. Furthermore, the sleeve also blocks ambient noise, improving the signal-to-noise ratio.
[0012] In addition, the outer wall of the sleeve body can be provided with a plurality of annular check rings. The edges of the check rings are provided with check flanges. When installing the noise reduction sleeve, the user can directly insert the sleeve into the gap between the decorative panels of the car roof, or other suitable locations. The check rings and check flanges can effectively prevent the sleeve from falling off, with significant effects. The noise reduction sleeve has excellent air permeability and moisture absorption, and can adapt to different environmental conditions. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention. Example
[0022] like Figures 1 to 4 As shown, the microphone assembly with a foam structure includes a microphone body 1 and a noise reduction sleeve 2. The noise reduction sleeve 2 includes a cap-shaped sleeve body 21. The sleeve body 21 has an installation cavity 22 formed inside. The inner wall of the installation cavity 22 is provided with a plurality of wedge-shaped clamping ribs 23.
[0023] In addition, a plurality of anti-slip protrusions 24 are provided on the inner wall of the clamping rib 23 .
[0024] It should be noted that the clamping ribs 23 gradually converge toward the top of the noise reduction sleeve 2 .
[0025] The noise reduction sleeve 2 is formed of high-density foam in one piece, so that the noise reduction sleeve 2 has a certain hardness and can effectively protect the microphone body 1.
[0026] The working method of the microphone assembly with a foam structure is described below.
[0027] like Figure 2 As shown, when installing the microphone body 1, the microphone body 1 is directly inserted into the installation cavity 22 of the noise reduction sleeve 2. During the installation process, the outer wall of the microphone body 1 squeezes the anti-slip protrusions 24 of the clamping ribs 23 until the microphone body 1 is inserted into the top of the installation cavity 22.
[0028] Since the clamping ribs 23 gradually converge toward the top of the noise reduction sleeve 2, they can automatically adapt to the outer diameter of the microphone body 1 and are suitable for installing microphone bodies 1 of different outer diameters. In addition, the anti-slip protrusions 24 prevent the microphone body 1 from slipping out of the noise reduction sleeve 2.
[0029] Because the microphone body 1 is located inside the noise-canceling sleeve 2, the sleeve 2 acts as a vibration dampener and soundproofing device, significantly improving the clarity and quality of sound pickup. The sleeve 2 effectively absorbs and attenuates mechanical vibrations, reducing their interference with sound pickup and resulting in purer and clearer sound. Furthermore, the sleeve 2 blocks ambient noise, improving the signal-to-noise ratio.
[0030] In addition, the noise reduction sleeve 2 has good air permeability and moisture absorption, and can adapt to different environmental conditions. Example
[0031] like Figure 5 and Figure 6 As shown, a plurality of annular check rings 25 are provided on the outer wall of the sleeve body 21 .
[0032] In addition, a non-return flange 251 is provided on the edge of the non-return ring 25 .
[0033] The working method of the microphone assembly with a foam structure is described below.
[0034] When installing the noise reduction sleeve 2, the user can directly insert the noise reduction sleeve 2 into the gap of the decorative panel of the car roof, or other suitable places, and use the non-return ring 25 and the non-return flange 251 to effectively prevent the noise reduction sleeve 2 from falling off, with obvious effect.
[0035] Without limitation to this, any changes or substitutions that are not conceived through creative work should be included in the scope of protection of this utility model. Therefore, the scope of protection of this utility model should be based on the scope of protection defined in the claims.
