📢 Introduction:
This DIY speaker was designed for the MakerWorld “Reusing Cardboard Spools Design Contest,” aiming to transform used cardboard spools into a useful and aesthetically pleasing object.
🔊 No electronics needed! This design utilizes a principle of passive amplification, where the shape and materials optimize sound propagation and resonance, without batteries or circuitry. A simple, effective, and ecological approach! 🌱
🔧 Features:
✅ Recycled materials: cardboard spool body ♻️
✅ 3D-printed PLA base for a perfect fit
✅ Passive amplification: the phone’s sound is channeled and resonates within the structure for clearer, more powerful audio
✅ Compatible with various smartphone models 📱
🎵 How it works?
The speaker amplifies sound through a combination of acoustic conduction and resonance:
1️⃣ Sound concentration: The sound emitted by the phone’s speaker is directed into a conduit designed to maximize its propagation.
2️⃣ Natural resonance: The cardboard cavity acts as a resonance chamber that increases perceived volume and enhances clarity of the sound.
3️⃣ Homogenous diffusion: The cylindrical design allows for better sound dispersion in the environment.
A principle similar to vintage gramophones 🎶 but with a modern twist!
