iBamboo Speaker – iBamboo Speaker for iPhone
The speaker consists of a piece of bamboo, open on both ends and machined in a way that allows you to place it on a flat surface and insert your iPhone 6 at the top. The natural resonance of the hollow bamboo speaker body amplifies sound. This unique property makes bamboo an ideal material for making an all-natural, no-power-needed iPhone amplifier.
