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 ...

Electret microphones are capable of high-quality output, and are prized for their smooth frequency response. However, unlike other types, they can’t simply be plugged directly into a mixing desk.

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 ...

Power is necessary for establishing the capacitor plate voltage and is also needed to power the microphone electronics. An electret microphone is a type of condenser microphone…[in which] 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 ...

West, now a professor of electrical and computer engineering at Johns Hopkins University, invented the electret microphone in the early 1960s. Today, West's invention accounts for 90 percent of ...

Of all of the types of microphones in use today, the electret microphone is the most commonly used version; 90 percent of all microphones used today are of the electret variety, resulting in ...

Dublin, Aug. 07, 2023 (GLOBE NEWSWIRE) -- The "Microphone Market by Technology (MEMS, Electret), MEMS Type (Analog, Digital), Communication Technology (Wired ...

West is the co-inventor of the electret microphone used in all of those devices and more. It’s estimated that over 90 percent of the microphones in use today are electret mics, and more than 2 ...
