Laser Light Show: Sound Visualized

Visit my website for more details: https://souzoumaker.com/project/2018/11/26/visualizing-sound.html This project came about after watching this video (https://youtu.be/C-V1uXeyGmg) 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. 0:00 - Frequency sweep 0:22 - 381 + 326 Hz 0:36 - 250 + 326 Hz 0:43 - 100 + 250 Hz 0:48 - 100 + 250 + 500 Hz 0:52 - 101 + 200 + 300 Hz 1:03 - 1 + 100 + 200 Hz 1:12 - 1 + 326 Hz 1:21 - 1 + 2 + 200 Hz 1:32 - "Light by Jorge Mendez"
