How do speakers work? Incredibly small, yet impressively loud.

Speakers weigh less than a dime but can be heard throughout a massive room. How do they make such intricate sounds while being so small? This fundamental lesson gets into the components of a smartphone's speaker as well as their function.

This animation was done entirely with Blender using 5 main scenes. The phone is my former LGV10 that got a 2nd life as Blender models. Most of the models were built using pictures taken with a V550 6,400dpi scanner, other pictures were taken using a DSLR. Luckily a lot of smartphone components are pretty flat and I could get rather high-resolution images with the scanner. If you have any questions or comments, I would be more than happy to hear them!

I am an engineer that wants to get others excited about engineering as well. I worked 8 years as an electrical and mechanical engineer on subsystems in machines that make microchips, specifically on Ion Implanters. I want to inspire others to get into engineering, so I decided to learn Blender. Eventually, I left my engineering job so I could make high-quality educational engineering videos for YouTube. My hobbies are: cooking, inner tube water polo, frisbee, and lindy hop dancing.


  1. Amazing work. I would love to see a video with your approach to hard surface modeling in blender. I'm currently trying to learn and I'm finding it somewhat dificult...

    Love the YouTube channel btw. Keep going!
