Horn shapes were widely used by the ancient Greeks. They designed circular arenas which opened like funnels where if performers whispered on stage, their voices could be clearly heard from the uppermost seats. This is because of the unique characteristics of the acoustic horn which maximizes the efficiency with which sound waves are transferred to air from their source.
When the first gramophone was invented in 1898, its horn amplified the minute mechanical oscillations of a pin running along a disc to produce sounds that could be heard by the human ear.
My proposal matches this history with modern technology. Using a single sheet of cardboard, I created an amplifier that turns sounds from a smartphone into music that can fill an entire room.
Instructions:
Score the cardboard and cut the pieces.
Scoring the cardboard allows it to bend seamlessly.
Assemble the horn by inserting the interlocking dovetail joints into each other.
Assemble the phone dock and slide it onto the horn.
The horn is now complete, insert your phone and enjoy amplified music.
