2. Electret microphone - Wikipedia

   en.wikipedia.org/wiki/Electret_microphone

   Sound waves move the diaphragm, changing the capacitance C, which produces a corresponding voltage change across the capacitor of ΔV = ⁠ Q / ΔC ⁠. [1] The electret's constant charge eliminates the need for the polarizing power supply required for non-electret condenser microphones , though a preamplifier is typically incorporated to boost ...

4. Microphone - Wikipedia

   en.wikipedia.org/wiki/Microphone

   The condenser microphone, invented at Western Electric in 1916 by E. C. Wente, [22] is also called a capacitor microphone or electrostatic microphone—capacitors were historically called condensers. The diaphragm acts as one plate of a capacitor, and audio vibrations produce changes in the distance between the plates.

   Shure Inc. is an audio products corporation headquartered in the USA. It was founded by Sidney N. Shure in Chicago, Illinois, in 1925 as a supplier of radio parts kits. The company became a manufacturer of consumer and professional audio-electronics including microphones, wireless microphone systems, phonograph cartridges, discussion systems, mixers, and digital signal processing.

7. Phantom power - Wikipedia

   en.wikipedia.org/wiki/Phantom_Power

   Mid-1970s and later condenser microphones designed for 48-volt phantom powering often require much more current (e.g., 2–4 mA for Neumann transformerless microphones, 4–5 mA for the Schoeps CMC ("Colette") series and Josephson microphones, 5–6 mA for most Shure KSM-series microphones, 8 mA for CAD Equiteks and 10 mA for Earthworks). The ...
