|Just some generic info:|
Screw holding the pieces together may be covered by rubber caps acting as cushions or they're under the speaker grill or the thing is glued together. Or I guess it's possible it snaps together. Take a small flat blade screwdirver and push down along the seam between the two pieces If you find a spot where it 'gives' that's probably where one of the snap tabs is that holds it together. It's going to be hard finding all the tabs and giving each just enough pressure to release but not so much that it breaks.
