The speaker in this is held on by those round, push-on steel washers. The
washers just push over plastic pins that are molded into the case.

I'm saying "washers" for lack of a better name. They are round, about ½" in
diameter, and the hole in the centre has slits that allow it to flex as its
pushed on.

I want to know the trick to getting them off without snapping the pins they
are on. Anyone have an idea?
