Anyone Know of a device that can plug into laptop so it can play music through my radio

[help_needed!]

Hi all
I've got an ipod and have bought a device that lets me play my music through radio waves on my stereo speakers, which has come in very handy.

I was wondering if anyone knew of a similar gadget that i can use on my laptop.

I already have AV leads which i can connect but these can a bit dangerous with my toddler.
Thanks
