What it does
- Passive speaker amplifies phone sound without batteries or electronics

- 3D-printed design demonstrates how sound waves can be physically amplified
- Perfect for science and music education projects
- Part one of a two-part sound characteristics curriculum
This 3D-printed passive speaker is designed to teach the fundamentals of sound through direct experimentation. By placing your compatible iPhone in the speaker cavity, students can observe how sound vibrations are amplified without any batteries, electronics, or external power, making it an ideal tool for understanding acoustics in the classroom.
The speaker demonstrates key concepts including vibration, echo, reverb, and decibel levels while connecting sound science directly to 3D design and printing. This hands-on approach helps students grasp how sound is a physical phenomenon that can be shaped and amplified through geometric design.
Ideal for science projects, music education, and maker programs. Works as part one of a complete two-part sound lesson, with part two guiding students to design and print their own custom speaker systems.

Printed plastic is strong for its size, but it is not metal. We have not load tested this design, so we do not publish a weight rating. Keep it out of a hot car and away from open flame.
