 * Dynamic Microphone**

Purpose
The main purpose of a microphone is to turn your voice into electricity. It helps it project your voice through larger crowds or simply to get other people's attention. A microphone is used for so many events and concerts through out the world. They are a sturdy object and can resilient rough handling. They are better suited for high volume levels, such as amplifiers or musical instruments.

Energy
Dynamic microphones take advantage of eletromagnet effects. Electromagnet effects are when a magnet moves past a coil or a wire and causes the magnet to start up the current.

Controls
The controls on the microphone are on the front part of the body that turns the microphone on and off. Also when you speak through the mesh wiring, there is a sensor that senses your voice and makes your voice into energy.

Materials
The essential materials that a microphone to work are magnet, coil, diaphragm, and wire media type="file" key="Movie 99-iPhone.m4v"

Science
The scientific principle of electromagnetism is central to the operation of a dynamic microphone. Electromagnetism is the phenomena with electric and magnetic fields and their interactions with each other and with electric charges and currents.

Design
The inside of the microphone starts out with a needle attached to a metal diaphragm. The needle will strach a pattern onto a piece of foil when you speak into it. When you spoke the different pressures in the air made the diaphragm move, which made the needle move and record onto the piece of foil.

Here is a site where it explains the diagram inside of a microphone and a picture of what I made next to this: [|Design of Microphone]

Evolution
In the future I think the microphone should be no longer visible. When people are performing on stage they have to hold onto the microphone and it sometimes justs gets in the way. Some people will use the headsets and sing into them but they could start to get annoying as well. Well to solve this problems we could simply make them no longer visible and you don't have to worry about holding somthing or having your head hurt. The best place to put the non-visible microphone would be behing the ear. When you speak the microphone will pick up on your voice and project to the large crowds. I think this idea will help alot of music groups perform more this at their concerts and not have to worry about holding a mircophone.
