Passive speaker amplifies phone sound without batteries or electronics
Teach sound vibration, resonance, and acoustics with hands-on learning
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.
