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

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.
Which is the best moving coil type instrument to convert sound to electricity?
IF you use speaker as microphone, you can use it as a transducer to convert soun energy into electrical signals
What happens when a permanent magnet moving coil instrument be connected in an ac current?
The torque on the moving coil will reverse at twice the frequency of the supply, causing the pointer to vibrate. High-quality a.c. measuring instruments that incorporate a moving coil are, of course, common but incorporate a rectification circuit to supply the coil.
Is Voltmeter is a moving iron Instrument or moving coil instrument?
If this is a homework related question, you really should consider trying to solve it yourself before looking at this answer. Otherwise, the value of the lesson, and the reinforcement provided by the assignment, will be lost to you.A moving coil measuring instrument has a coil attached to the indicator, surrounded by a magnet.A moving iron measuring instrument has a magnet attached to the indicator, surrounded by a coil.In both cases, the indicator is driven by magnetic torque caused by current flow in the coil.
Specifically what are moving coil and moving iron used for measuring?
If you are questioning about different relay (contactor) constructions, the terms moving coil and moving iron designate what part of the relay moves and carries the conductor that makes or breaks a circuit.
What type of microphone contains a moving coil?
Snake

Can a moving coil loud speaker be used as a moving coil microphone?
Yes, but with vey low sensitivity and poor frequency response.
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.

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.
What is the construction and working details of moving iron and moving coil ammeters and moving coil voltmeters?
Different b/w a moving coil instrument and a moving iron instrument
Is megger related to hot wire instrument moving coil or moving iron?
It is related to moving coil type instrument
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.
What is moving coil voltmeter?
mic or moving iron coil is instrument type works on ac and dc
What are the disadvantages of a moving coil galvanometer?
major disadvantage is that moving coil galvanometer is not suitable for a.c measurement
