This isn't just a mass produced speaker in a 3D printed case, but instead the speaker itself that has been 3D printed. Over complexity has been avoided to make a fun, simple, and sturdy little speaker. When connected to an Arduino, it pushes out a decent amount of volume and sound quality for its size. It can also play regular music with a proper driver.

Materials List:

• Very thin magnet wire, 30+++ gauge — the resistance of the coil should be around 10Ω
• Six 6x32 half-inch machine screws, two 6x32 nuts
• Three 3x12 mm neodymium magnets

How it works

Three neodymium magnets create a permanent magnetic field. When an electric current passes through the coil, it creates a temporary magnetic field of its own which attracts the permanent magnet's magnetic field. If the current tot he coil is fluctuated over sound, it cause vibration which in turn is what we perceive as sound.

This speaker has two versions:

Simple version

A simple speaker box that lays flat on a table. The wire is routed out the side of the box.

Parts needed:

Lower speaker box (shown in blue)
Upper speaker box (shown in white)
Cooler version

The speaker box is attached to the base with the two machine screws and nuts. The wire will be routed out of the back of the speaker box through the white stand.
