What is Microphone?
[[File:Neumann U87 microphone 20050905.jpg|100px|right|thumb|A [[Georg Neumann|Neumann]] U87 capacitor microphone.]] A '''microphone''', sometimes referred to as a '''mike''' or '''mic''' (both [[International Phonetic Alphabet|IPA pronunciation]]: {{IPA|[maɪk]}}), converts [[sound]] into an [[Signal (electrical engineering)|electrical signal]]. Microphones are used in many applications such as [[telephone]]s, [[tape recorder]]s, [[hearing aid]]s, [[motion picture]] production, live and recorded [[audio engineering]], in [[radio]] and [[television]] broadcasting and in [[computer]]s for [[recording]] voice. == Kinds of Microphones == [[Sound]] passes through the air in waves, and as was said above, the microphone turns the sound wave into an electrical wave. Different kinds of microphones will turn the sound waves into [[electricity]] in different ways.<ref>{{Cite web|last=Olson|first=Harry|date=2020-04-24|title=All Types of Microphones Explained with their uses|url=https://bestshotgunmic.com/types-of-microphones-explained/|access-date=2020-09-13|website=Best Shotgun Mic|language=en-US|archive-date=2020-10-29|archive-url=https://web.archive.org/web/20201029231842/https://bestshotgunmic.com/types-of-microphones-explained/|url-status=dead}}</ref> * [[File:BSPC 19 i Nyborg Danmark 2009 (4).jpg|thumb|100x100px|A Shure witness microphone ]]'''Carbon button''' - This is the first kind to become commonplace, being used in most 20th century telephones. Sound waves, by compressing and decompressing a piece of [[carbon]], change the amount of [[electric current]] flowing in the wire, thus creating electrical waves. This kind became rarer late in the century, due in part to lack of [[high fidelity]]. * '''Dynamic''' - This uses a round plastic or rubber disk connected to a wire coil in order to turn sound into electricity. The sound wave hits the disk which vibrates as a result. This vibration moves the coil back and forth near a magnet very quickly in order to create an electrical current. The dynamic microphone i
