Turn Your iPhone Audio Into Brass
In this video, we watch how a trumpet can be used to amplify sound from a smartphone speaker, creating a nice, brassy sound that sounds similar to the timbre of a record player.
From the video’s description:
“I made it from a broken trumpet and a fistful of scrap metal. The unit uses no external power or batteries, has no moving parts, and is entirely self-contained”
