First you'll need to cut open the echo mic.

I used a saw for this and just sawed along the side until I could get to the insides.
The spring might be stuck inside, but with some force on the outsides of the mic, you should be able to get one side to detach.

The other side however, is a bit tricker.
I used a pen and a paperclip to kind of "fish" the other end out.

FInally, you'll have a detached spring! :)
