Board screwed into place and speaker glued to silicone gasket to cut down on vibration noise. Holes drilled on other side to serve as a speaker "grille". Speaker box will be under layout module, and battery box and play button on top of layout surface. The sound clip is actually 2 minutes long, but 7 seconds is all I could load (5 mb attachment limit). Nonetheless, placing the speaker inside the box improves the loudness and sound quality due to the echoing inside.
