The coil is basically an electro magnet which is used to move the cone or diaphragm in the headphone.
It works like this....
Next to the coil is a permanent magnet, when the currant from your iPod or audio device travels up the cable and into the coil it makes the coil repel the magnet and that in turn moves the diaphragm to produce the sound

What type of microphone contains a moving coil?
Snake
Is it possible to use a moving coil loudspeaker instead of a moving coil microphone?
Yes, but the sensitivity and frequency response will be very poor. The diaphragm on a microphone, corresponding to the voice coil and cone on a speaker, is extraordinarily light and compliant.
Whrite a Breif note on moving coil microphone?
A moving-coil microphone contains a diaphragm exposed to sound waves. The diaphragm carries a coil placed in the magnetic field. The voltage induced in the coil is proportional to its amplitude of vibration, which, in turn, depends on the sound pressure.Moving-coil microphone. AP = acoustic pressure, Uo = output voltage, 1 = diaphragm, 2 = coil, 3 = permanent magnet, 4 = protection grid, 5 = case. Cheers ebs
What are words related to microphone?

Examples are:button microphone,capacitor microphone,carbon microphone,condenser microphone,contact microphone,dictaphone,digital microphone,dynamic microphone,electrostatic microphone,hydrophone,laser microphone,lavalier microphone,liquid microphone,mic, mike,moving coil microphone,omnidirectional microphone,parabolic microphone,pick-up,piezoelectric microphone,ribbon microphone,shotgun microphone, tap,throat microphone,unidirectional microphone,water microphone,wire-tap, wire-tapping,wireless microphone
What type of microphone is most similar to a speaker?
A dynamic microphone is most similar to a speaker. They both consist of a diaphragm, a voice coil and a magnet.
Can a moving coil loud speaker be used as a moving coil microphone?
Yes, but with vey low sensitivity and poor frequency response.
Can earphones be used a microphone when plugged into the microphone jack on a computer?
Not recommended, but yes many earphones will work but give very poor quality sound and probably not enough volume to be useful. Most earphones contain a small coil of wire on a movable form around a small magnet. The current sent from the PC earphone socket through the coil causes vibrations which can be heard. Making a noise close to the earphone will cause the coil to vibrate and generate a small current which the microphone socket should be able to pick up. Some microphone inputs will expect an electret condenser microphone and so will not work with a dynamic input.
How does amplification of sound take place?
Sound, which is actually waves of varying pressure in the air, is converted into electrical energy by a microphone, which is often a coil of wire suspended in a magnetic field. The waves of air pressure at the microphone cause the coil to move, which generates an electrical waveform that is, as much as possible, similar to the waves of air pressure at the microphone. The electrical waveform is amplified by several stages of active electronic devices--either vacuum tubes or transistors--until it has enough power to drive an electrodynamic loudspeaker. The speaker is another coil of wire suspended in a magnetic field--just like the microphone, but operated in reverse. The varying electrical current in the coil causes the coil to move within the magnetic field. The coil is attached to a plastic or fiber cone; when it moves, it can displace enough air to create large waves of air pressure. In this way, the speaker can produce pressure waves in the air that are much larger than the ones that originally reached the microphone.
How does a moving coil microphone work?
A moving coil microphone is used for a variety of audio applications primarily for recording and sound reinforcement. It can be used in a wide range of situations from professional recording studios to live performances and is the most common type of microphone in use today. Its versatility and reliability make it a great choice for many different applications. Recording: Moving coil microphones are used to capture audio in the studio such as vocal and instrumental performances spoken audio and sound effects. Live sound reinforcement: Moving coil microphones can be used in live sound reinforcement situations such as concerts theater performances and public speaking events. Broadcast: Moving coil microphones are used in broadcasting applications such as radio and television.Moving coil microphones offer a number of advantages including high sensitivity low self-noise and low distortion. They are also relatively inexpensive and easy to use making them a popular choice for many different audio applications.
How can a microphone convert energy?
Most microphones sold today are "dynamic" microphones. They contain a tube (known as a coil former) with a coil of wire wrapped around it, a magnet inside the coil former, and a diaphragm glued to one end of the coil former. The diaphragm moves the coil former back and forth across the magnet; as it moves, electricity is generated in the coil.
Is microphone a input or output device?
A microphone is (put simply) a magnet inside a coil of wire. When the noise vibrations hit the magnet it moves creating an electronic field around the wire. That electricity goes into your computer.A microphone is an input device.
What is the part of a microphone called that picks up sound?
In general, this part of the microphone is called the transducer.For Condenser microphones, a diaphragm-like transducer is used.For Dynamic microphones, either a ribbon-like or moving coil transducer is used.
