Can the film outside the speaker still be used if it has aging cracks?

It can be used, but it will affect the sound effect. With the increase of use, it will expand along the damaged place, which will also affect the quality of sound transmission. The voice will become hoarse, broken or even completely damaged. In order to prevent this phenomenon, it is necessary to prevent the slight delay and repair the broken edge as soon as possible, which can be coated with silica gel or cotton paper.
