Makeshift Speaker

What it does

A makeshift speaker designed and built over the course of 7 hours! It is capable of producing sound around 80 dB at a distance of 1 metre and won the 2025 Tron Day competition at the University of Waterloo.

The Process

As a team of four, we researched and applied sound principles to find the optimal speaker design for minimum sound leakage. We drew prototypes on paper and orthographic projections of the final version on AutoCAD. Using cardboard, hot glue, and a pair of scissors, we made a speaker box with two circular holes (one for the speaker itself, another smaller one to funnel the vibrations from inside the box to its front face). We also programmed a premade PCB and used the Mozzi library in the Arduino IDE to demonstrate noise cancelling.
