This project came about after watching a video by a youtuber who described a way to visualize sound with a laser. It works by taking a speaker, stretching a balloon over it, and centering a mirror fragment on the balloon. Sound is played through the speaker and a laser pointer is shined on the mirror. The sound causes the mirror to vibrate, creating a laser show. I designed the speaker above so I can mix frequencies and play with the various shapes. Since I don’t own a speaker, I thought this would also be a good opportunity to learn how sound systems work while making a high quality speaker.
