When designing a microphone assembly the other day, I reached for an electret condenser microphone capsule without thinking. To be strictly accurate I ordered a pack of them, these small ...

Work on the electret condenser microphones dates back to as early as 1928. Eventually, a few microphone models with wax electrets were offered commercially in the late 1930s. (See reference [1] at the ...

In two articles thus far (RW Engineering Extra, Aug. 10 and Oct. 19, 2016), we’ve traced the origins of electret condenser microphones to their externally-polarized ancestor, patented in 1916. One ...

almost all microphones in cell phones and other electronics were a type of condenser microphone called the electret microphone. The fact that this type of microphone is cheap and easy enough to ...

An electret microphone is a type of condenser microphone…[in which] the externally applied charge used for a conventional condenser microphone is replaced by a permanent charge in an electret material ...

In checking my lavalliere microphone, I found that it’s an electret condenser microphone, so all that needed is to rig up a suitable electret condenser microphone preamplifier circuit to get great ...

High-end microphones are wildly expensive ... typically use omnidirectional electret condenser capsules. In this project, Brad Peterson accomplishes this by mounting a pair of cheap Behringer ...

The microphone connects via USB, has a frequency response of 20Hz-20kHz, and the condenser type is electret. However, the downside is that it can pick up keyboard clicks and does not have the best ...

As such, condenser mics usually have a more accurate frequency response curve than dynamic mics. Electret mics are a form of condenser mic where the capacitor dielectric is permanently charged without ...
