The project
The goal of this project was to make a Microphone.
My microphone was made out of
The three essential components of my microphone was the coil wire, the cup with plastic wrap, and the magnet.
I connect my microphone to a computer.
In order for my microphone to pick up my voice, I gat to be close to it.
The physics
The sound make the objects
When a coil of wire is moving relative to a permanent magnet make magnetic electricity.
How It Works
The kind of energy that my microphone convert sound energy is into…
My microphone is a special example of a machine that I built before. What kind of machine is it?
when I speak the diaphragm
That coil wire is attached to audio jack.
The magnet is inside the straw.
When I push down on the diaphragm, the coil of wire get close to the straw, the wire or to the table.
when you tap the diaphragm with my finger in the coil of wire you make electricity.
What happens in the coil of wire when you speak into the microphone?
A nearby magnet move and sound is produced.
