Here’s a pretty cool DIY project. This Instructable shows you how to create this really fine looking speaker using some coconut shells and an old set of computer speakers. In a nutshell (or should I say coconut shell), what was done was to simply replace the plastic casing with a coconut casing.
Just hacksaw your coconut so the opening fits the size of the speaker grill. Drill a hole in the back for the wire to pass through. To get that sleek look you need to sand your coconut until it’s smooth, or you could leave it looking rough like something out of Gilligan’s Island. Then you glue the speaker into the opening, cut a small piece of bamboo for the base, and you’re done. Easy as that.
