Speaker and hard disks magnets are shielded with a thick piece of steel or similar material, which act as a "conductor" of magnetic fields.
Apr 30, 2014 at 20:12 comment added Razib Ali Hi Kevin, thank you so very much for appropriate answer! I also found the same that you mentioned here. I could not find such material! But I was quite interested about the metal or something like that that holds the very strong magnets of Hard disks and speakers! What about them? Can you please enlighten me about those?
