The electret microphone is based on the electret capacitor, which is a special capacitor with quasi-permanent charge. Vibrations in the air are picked up by the capacitor, which generates an equivalent vibrating electrical signal. Unlike a traditional condensor (another name for capacitor) microphone, the electret does not require a power source.

Microphone can do this job.
How does microphone mixer work?
To combine the signals of multiple microphones, you add (sum) their electrical voltages, just like the sound waves from multiple singers sum in the air. To measure the voltage produced by the microphone without affecting it, you need amplifier circuits with high input impedances. These amplifiers must also have a widely variable gain (trim control), since there are many different microphones with different output levels, and you want them all internally at the same level. Then you might have EQ or other controls to manipulate the sound of each microphone. Then there is an overall volume control for each microphone, for setting the relative level of each. Then the weighted signals go into a summing amplifier to be added together, and then to an output.
Microphone gives dc or ac output?
Microphone gives ac output. Microphone converts sound energy to electrical energy. Due to vibration of Carbon diaphragm the resistance varies so that the amplitude of current varies. That is not entirely true. A microphone element produces a very small DC sine wave output, all of it above the zero line. It can be made to have an AC ouput if a circuit is added to do so, as an amplifier which provides the negative component. Thus, half (or sometimes less than half) of the sine wave will be below the zero line. Otherwise, circuitry may be integral to the mic.

What is a roll off filter of a microphone?
The roll off filter removes low frequencies. Usually at about 75 HZ and bellow.
Where can one purchase a Sony ECM DS70P Electret Condenser stereo microphone?
One can purchase a Sony ECM DS70P Electret Condenser stereo microphone from the Sony store for $74.99. However, one can try to get microphone for a cheaper price on Amazon or eBay.
Is a electret microphone a transducer?
yes, it transduces sound waves to voltage variations
What battery does the Sony electret condenser microphone ecm 150 use?
Energizer EPX76
Who invented the electret microphone?
James E. West and Gerhard M. Sessler did together.
Who is James E West?
The inventor of the —foil electret microphone with Gerhard Sessler in 1964 in the Bell Lab.
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.
What kind of microphone can be used for breadboard purpose?
Good, cheap electret inserts work fine - you do need to provide some power, but I expect you're making powered circuits anyway. Check out hobbies/electronics magazines/websites. Expect some tens of millivolts from normal voice levals.
How do you work the microphone on the iPad 1?
Open a recording app. The microphone will automatically enabled.
Does a microphone work with out a amp?
No, really not.
How do i use a microphone?
First it is very important to chose the right microphone. There are condenser microphones, ribbon microphones, dynamic microphones, and there are electret microphones. There are some different characteristics: omni directional, wide cardioid, cardioid, super cardioid, hyper cardoid and figure-of-eight. There are microphones with small diaphragm diameters and with large diaphragm diameters. There are expensive high quality studio microphones and less ideal very cheap Chinese mics. When you have found the right microphone, then you can start to ask where to put this microphone to which musical instrument or voice.
Will a microphone from another game work on rock band?
As long as it is USB, any microphone should work with Rock Band. In fact, the Xbox Live headset even works as a microphone for this game.
