Definition of Microphone and Amplifier
Microphone: A microphone is an acoustic-to-electric transducer or a sensor that converts sound into electrical signal. The first microphone was invented by Emile Berliner in 1876, for telephone voice transmission. Most microphones that are used nowadays are dynamic microphones, condenser microphones etc and they use light modulation to produce an electrical voltage signal from mechanical vibration.
Amplifier: An Amplifier is a device that changes in fact usually increases, the amplitude of a signal. The relationship between the inputs to the output of an amplifier is expressed as a function of the input frequency.
Usually the term amplifier usually describes an electronic amplifier, in which the input is often a voltage or a current. A related device that converts signals of one type to another is a transformer or a sensor. But, none of these amplify power as amplifier.
Application Areas of Microphone and Amplifier
Microphones are used in many applications such as telephones, tape recorders, karaoke systems, hearing aids, motion picture production, live and recorded audio engineering, megaphones, in radio and television broadcasting and in computers for recording voice, speech recognition, VoIP, and for non-acoustic purposes such as ultrasonic checking or knock sensors.
While amplifiers drive the loudspeakers used in PA systems in order to make the human voice louder or play recorded music. Amplifiers are classified according to the input they are provided to amplify such as a guitar amplifier, for performing with an electric guitar and many more
