Theoretically, there is a certain gap between the net and the diaphragm, and the concave part will not affect the sound quality if it does not touch the diaphragm.
Dust-proof net is also called dust-proof cloth, which mainly plays the role of dust prevention. Dust-proof net is generally placed outside the horn to prevent dust from entering the horn sound film and causing accumulation, which will lead to poor sound of the horn.
So it's okay to go in, but protect the headphones.
Extended data
There are three main factors that affect the sound quality of headphones: diaphragm, decoding, related circuits and tuning. Among them, although the diaphragm is inconspicuous, it is the element that ultimately produces sound.
An excellent and ideal earphone diaphragm should have: the mass density should be relatively small, thus making the diaphragm itself lighter; Young's modulus of material mechanics is relatively large, which can make the diaphragm itself have good rigidity. In addition, it also needs an appropriate internal damping factor to absorb unnecessary clutter and the distortion brought to the diaphragm during vibration.
If the diaphragm is light and thin, it is naturally impossible to have high strength. The earphone is equivalent to a small speaker, and the diaphragm is smaller and more fragile. The diaphragm of most earphone units is designed with a circle of surrounding "ribs" to increase the rigidity of the diaphragm. However, different designs of ribs, domes and other parts will bring different sounds.
However, it is the game headset that requires a higher degree of detail restoration. What game headphones need is the ability of 3D positioning and detail restoration, so as to realize the position of listening and speaking. Traditional game headphones mostly use PVC diaphragm, although the performance has been good. Game headphones made of graphene will greatly enhance the performance of details.
