The world’s first modern loudspeakers were made using just the paper, magnets, and connecting wire. The audio industry has come a long way from 1921 and today, highly sophisticated sound systems are designed using the ferrofluid and synthetic fibers.
Although a high-quality speaker can cost you thousands of dollars, you can enjoy an exceptional audio experience using potato crisp as a diaphragm.
The audio could not get crisper than this, right? All you need is a few basic supplies and some genius hacks.
- 30-gauge magnet wire (almost 25 feet)
- Two 0.75” X 0.25” cylindrical magnets (the ones used in refrigerators will serve the purpose)
- Two cardboard strips, 0.25” X 1.5.”
- Cutting board
- One dowel of 6” length and 0.75” diameter
- A hot-glue gun
- Potato chips (use the thick cut for the optimum sound quality)
Step1: Voice Coil
Build three-eighth inches of a coil by twisting the magnetic wire around the dowel. However, remember to leave 12 inches of wire at each end. Put hot glue on the wire using a hot glue gun and allow it to cool. Use a sandpaper to remove one inch of paint from the ends of the wires.
Step 2: Speaker Assembly
Fold the strips cut from the cardboard to form a Z shape. Glue the magnets and the strips to the wooden board. Also, attach the coil to a potato chip using hot glue. Aligning the coil on the center of the magnet, use hot glue to stick a cardboard strip to each end of the potato chip.
Step 3: Enjoy the Crisp Sound Quality
Connect the wire ends to an amplified audio source and enjoy the crisp sound from your DIY potato crisp speaker.
