Second Sound / Loudspeaker

Second Sound
Second Sound

30 billion plastic bottles are thrown away every year and the most of them end up in landfill. It becomes a major hazard to our environment. The Second Sound aims at giving the waste bottles a second life to be something useful. It provides users a sticker with an instruction on the back. With the instruction, users can assemble a loudspeaker using waste bottles. Without high-technology and even electricity, it can reduce the loss of sound waves, and sounds can be scattered through the holes on the Second Sound.
