Can it be fixed? Plastic surrounding the speaker.

Hi there, I was wondering if the plastic surrounding the speaker can be fixed. The first picture was also like the second picture but I cleaned it up by removing the broken plastic pieces, sorry about the dust and dirt, got it from someone, I'm just inspecting it, its a JVC SX-F7TH speaker btw. Its still working with no problems at all, I don't know if it will cause a problem in the future.
