Meet The Tone, an extremely thin speaker for smartphones that is also foldable. As the world's thinnest speaker, The Tone also has no electrical components, no batteries, no wires and no additional battery drain from your phone.
The amplifier uses only shape and structure to enhance volume of the in-built smartphone speakers. The sound of the world's thinnest speaker is further enhanced by the patented aluminium panel, which was engineered in Germany.
Due to the lightweight material, The Tone weighs only 75g, and folds down in seconds to an amazing 3mm. Its unique design means it will work with any and every smartphone available now and in the future.
The team behind Tone are currently raising funds on Kickstarter where you can pre-order the thinnest speaker in the world from $35 a unit. It seems like a bargain to have the most portable, hi-tech future proof amplifier you can get for your phone.
