Phone Amplifier

thingiverse

This setup boosts your phone's sound output without any electronic components. The louder the sound, the denser the material used inside the horn. Snap-together design allows easy assembly of the horn and holder, which I advise against gluing together to ensure safe disassembly in case of a fall - they'll simply snap apart. Once separated, you can easily reattach them. This versatile system also enables quick switching between different horns for distinct sounds, requiring no additional support.
