Therefore, providing a plurality of through holes can increase the noise reduction effect, and the through holes are connected from the direction toward the noise reduction member to the direction away from the noise reduction member, which can guide the sound waves to the noise reduction member to further act on the energy of the sound waves, ensuring that the noise reduction member can effectively absorb the energy of the sound waves.

[0012] In this embodiment, a first mounting groove is provided on the inner wall of the shell, the noise reduction component is embedded in the first mounting groove, and the porous component is pressed onto the first mounting groove, and then the first mounting groove is used to accommodate the noise reduction component, thereby reducing the occupation of the internal space of the volute by the noise reduction component and the porous component, so as to ensure the airflow guidance effect of the volute, and the total amount of the noise reduction component can be increased to improve the noise reduction effect.

[0013] In some embodiments, optionally, there are multiple first installation grooves, and one porous member is pressed onto the multiple first installation grooves.

[0014] In this embodiment, there are multiple first installation grooves, and the first installation grooves can also consume the energy of sound waves.

The noise reduction component 120 and the porous component 130 are arranged on the inner side of the shell 110, and the porous component 130 is pressed on the noise reduction component 120. Then, the noise in the shell 110 can be transmitted to the noise reduction component 120 through the porous component 130, thereby achieving the effect of noise reduction and sound absorption, and reducing the noise generated by the fan or other electronic equipment.

[0045] The noise reduction element 120 may be foam or other sound absorbing materials.
