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
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
How is electricity transformed into sound?
1. Sound is energy. 2. Energy can be converted from one form to another. Picture a microphone. A simple device that has a permanent magnet, a coil of copper wire, and a thin diaphragm. The copper wire is coiled around a thin cylinder of paper so that it encircles the magnet without touching it. That coil is attached to the diaphragm and positioned over the magnet. When sound hits the thin diaphragm, the diaphragm vibrates moving the the copper coil back and forth over the magnet. This action creates electrical impulses in the coil. This is energy conversion. To see this in action, take a speaker apart. A microphone and a speaker work on the same principals only in reverse. If you connect a volt meter to the leads on a speaker and move the cone, you'll see the meter register small amounts of electricity.

What is type of input of loudspeaker?
A loudspeaker is a transducer; it converts one form of energy to another. In this case, electrical energy into acoustic (pressure) energy. Many types of loudspeaker can also be used as a microphone. This effect is known as reciprocity. An ordinary 'moving coil' loudspeaker will be quite a good microphone, when associated with appropriate amplifiers.
Do microphones use electromagnets?
The microphone works by producing a small induced voltage in a coil from the effect of sound waves hitting a diaphragm. It is very similar to a loudspeaker in reverse with a diaphragm instead of a paper cone. This type of microphone is called a moving coil microphone. The sound waves strike the diaphragm and move it backwards and forwards at the same frequency as the sound (like the way the ear drum is moved inside the ear). The moving diaphragm moves the coil backwards and forwards which induces a changing current at the same frequency as the sound. This changing current (called the signal) is sent to an amplifier which makes the changing current big enough to be used for recording or to drive loudspeakers. The loudspeaker reconverts the changing current back into the original sound. A microphone converts the sound energy into electrical energy.
How is an ear like a microphone?
The microphone has a diaphragm that is moved by the sound pressure of the sound waves. This sound pressure, measured in pascals, is converted by the microphone to the electric audio wave. Our auditory system has two ear drums that are similar to the microphone's diaphragm that delivers the sound wave to the inner ear. Only sound pressure (pascals) is moving the ear drums. Sound intensity (power) has nothing to do with this.
Why do people put duck tape on microphones at concerts?
It was just to make sure that all the equipments in the audio chain is working properly. For eg live sound, when you tap the mic and if the loudspeaker reproduce the tapping sound then you can make sure that all the equipments in the chain is working properly,your mic,amplifier,loudspeaker etc But i just want to tell you one more thing that tapping the microphone is not a good practise as it may spoil the diaphram.
What type of microphone contains a moving coil?
Snake
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 energy does a loudspeaker produce?
The energy is in the form of sound waves, which are moving air molecules, a form of kinetic energy.
Can a moving coil loud speaker be used as a moving coil microphone?
Yes, but with vey low sensitivity and poor frequency response.
What energy transfers take place in a speaker?
In an electric fan electric energy is converted into mechanical energy which makes the blades of the fan spin. On the other hand in a loudspeaker electric energy is converted into sound energy which produces the music.
How can a microphone and oscilloscope show a sound wave?
The microphone reacts to changes in air pressure and creates corresponding AC electical waveforms. The oscilloscope takes the AC waveforms and deflects a moving electron beam in a cathode ray tube, thus producing a moving display of the electrical waveform.
What did people do when they learned to grow food?
When people learned to grow food, it made it possible for them to settle down in one place instead of moving around to hunt for food.
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.
