Speaker on a crankshaft
thingiverse
I'm pushing the boundaries of creativity by finding innovative ways to make plastic produce sound. As a follow-up to my Mammond experiment, this test object aims to bring the concept of musical tones to life. An electric motor with a 3mm shaft diameter can be inserted into the crankshaft. By adjusting the voltage on the motor, you can easily change the pitch of the tone produced. If it yields good results, I plan to further explore how to connect 12 of these devices to a keyboard equipped with gears to achieve different pitches for each key.
