Determined to amplify the speaker on my cell phone with no added electricity, I turned to the only sustainable source feasible, Bamboo.  Each Bam-Boom Speaker Tube is entirely handcrafted, using the finest organic bamboo, personally harvested in my backyard.  

The tools which I use, are my trusty Swiss Army knife and a Japanese pull-saw purchased from Home Depot.
That looks REALLY cool, and using the bamboo as a resonant chamber is a very good idea. My guess would be that it makes the sound a little bassey, which might be good, but if you want to bring out the mid and treble sounds you might want to look at a conical &quot;horn&quot;. However cutting the bamboo at an angle as you have will deliver some similar effects. <br> <br>There's some excellent possibilities for learning about resonance and acoustics in this project, do think about doing a proper &quot;step by step&quot; with some discussion of alternative shapes and sizes.
Kudos to geronimo bambo for making my smartphone more useful and organic.<br><br>Dido on having more details:)
