C. Wente, is also called a capacitor microphone or electrostatic microphone—capacitors were historically called condensers.
There are two types, depending on the method of extracting the audio signal from the transducer: DC-biased microphones, and radio frequency (RF) or high frequency (HF) condenser microphones.]]> 2016-08-10 03:15:36 UTC https://padlet.com/wzmustaqeem/4n537r453pkx/wish/117855138 wzmustaqeem https://padlet.com/wzmustaqeem/4n537r453pkx/wish/117856033 First patent on foil electret microphone by G. M. Sessler et al. ]]> 2016-08-10 03:30:39 UTC https://padlet.com/wzmustaqeem/4n537r453pkx/wish/117856033 wzmustaqeem https://padlet.com/wzmustaqeem/4n537r453pkx/wish/117856458 An electret microphone is a type of capacitor microphone invented by Gerhard Sessler and Jim West at Bell laboratories in 1962.[20] The externally applied charge described above under condenser microphones is replaced by a permanent charge in an electret material. An electret is a ferroelectric material that has been permanently electrically charged or polarized. The name comes from electrostatic and magnet; a static charge is embedded in an electret by alignment of the static charges in the material, much the way a magnet is made by aligning the magnetic domains in a piece of iron.`]]> 2016-08-10 03:38:49 UTC https://padlet.com/wzmustaqeem/4n537r453pkx/wish/117856458 wzmustaqeem https://padlet.com/wzmustaqeem/4n537r453pkx/wish/118522009 EXAMPLES OF CONDENSER MICROPHONES]]> 2016-08-17 02:58:22 UTC https://padlet.com/wzmustaqeem/4n537r453pkx/wish/118522009
