Microphones enable many types of audio recording devices for purposes including communications of many kinds, as well as music and speech recording.]]> 2017-11-02 11:46:39 UTC https://padlet.com/haziqahbatrishia/p118a812llfl/wish/202844728 haziqahbatrishia https://padlet.com/haziqahbatrishia/p118a812llfl/wish/202853912 Microphones are used in many applications such as telephones, hearing aids, public address systems for concert halls and public events, motion picture production, live and recorded audio engineering, sound recording, two-way radios, megaphones, radio and television broadcasting, and in computers for recording voice, speech recognition, VoIP, and for non-acoustic purposes such as ultrasonic sensors or knock sensors.]]> 2017-11-02 12:14:24 UTC https://padlet.com/haziqahbatrishia/p118a812llfl/wish/202853912 haziqahbatrishia https://padlet.com/haziqahbatrishia/p118a812llfl/wish/202874701 1) CONDENSER MICROPHONE
Condenser microphones use the varied electrical charge of a capacitor with a diaphragm acting as a one of the plates of a capacitor. The plate is biased by a fixed charge, often from a battery which also amplifies the signal. Capacitance varies with movement of the diaphragm in relation to the other plates providing the means to record the sound in electrical signal. Electret microphones used in cell phones and computers are a type of condenser microphone that use a polarized ferroelectric material.]]> 2017-11-02 13:04:29 UTC https://padlet.com/haziqahbatrishia/p118a812llfl/wish/202874701 haziqahbatrishia https://padlet.com/haziqahbatrishia/p118a812llfl/wish/202877659 2) DYNAMIC MICROPHONE
Dynamic microphones use a coil suspended in a magnetic field that may be attached to multiple membranes for extended frequency response. They use electro-magneticinductionto produce the signal. These microphones are well suited to stage performance.]]> 2017-11-02 13:10:42 UTC https://padlet.com/haziqahbatrishia/p118a812llfl/wish/202877659 haziqahbatrishia https://padlet.com/haziqahbatrishia/p118a812llfl/wish/202881360 3) RIBBON MICROPHONE 
Ribbon microphone uses a thin, usually corrugated metal ribbon suspended in a magnetic field. The ribbon is electrically connected to the microphone's output, and its vibration within the magnetic field generates the electrical signal. Ribbon microphones are similar to moving coil microphones in the sense that both produce sound by means of magnetic induction.]]> 2017-11-02 13:18:01 UTC https://padlet.com/haziqahbatrishia/p118a812llfl/wish/202881360
