Thank you for the response. Actually, I found it, even if I spent several hours. I was going to abandon the search when i digited "fabric of speakers texture" on Google Images and, with enormous surprise, i found the image I attach here.

Anyway, now I have to create properly the logo. I know I'm off topic now, but if someone have a minute, could he tell me how should I make the light lines and effects which my original photo have?
