Speaker problems?

I have an iHome external speaker that has absolutely NO problem playing music from my phone. However, when I connect it to my MBP, it sounds staticy..... I thought it was because my external speaker was too close to my MBP, but I moved it farther apart, and it is still noticeable on my speaker. Is the iHome compatible with notebooks?

 

I think I know what you are saying, I have a cable that I can't remember what it's called. Can you please tell the kind of cable you are talking about and maybe it'll "ring a bell for me"?

Thank you.

 

I have something that I can't think of what the name of it's called. Its a black cord that can go into the headphone jacks of my iPod, MBP, and iPhone. I just can't remember what the cord is called.
