microphone to portable speaker

[Lewis_32]

Hello all
I am trying to find a way of linking a microphone directly into a portable speaker, I know I can buy "portable karaoke" machines to do this but i am looking for the mic to be a 3.5mm, what would be the best way to do this? 3.5mm adapter into a portable karaoke machine?

any ideas / thoughts will be much appreciated!
