my speakers pick up radio

i don't know why they do, but my speakers have been picking up fm and am frequencies and it's quite creepy at times and very frustrating when i'm trying to watch a movie or listen to music. Does anybody out there know how to fix this problem, if so please please help me, these things are getting on my nerves so bad that i'm just about to throw them away and go without sound. thank you for any help in advance

 

If they were cheap, they probably aren't properly shielded.
If they weren't cheap, you might have malware and it is connecting to some internet streaming radio site.
