Microphones

 * Microphones are devices used to input sound.
 * The basic principle of microphones is converting sound into an electrical signal. Therefore it converts anolog (sound) into digital (the electrical signal).
 * Analog: Kind of like a continuous stream of information. The human way of processing information.
 * Digital: Basically, data in ones and zeros. This is the data in computers.
 * Smarty pants term: TRANSDUCER. A "transducer" is something that turns energy into other forms. (From Acoustical energy [sound waves] into electrical energy [the audio signal])
 * All microphones need a diaphragm. The diaphragm is a little material bit that vibrates when it is hit by a sound wave. When the diaphragm vibrates, it makes other things in the microphone to vibrate and this creates the audio signal.
 * Sound is detected by the microphone and an electrical signal is transmitted to the computer. The digital data from the computer goes to the loudspeaker which turns the digital data back into analog so we can hear it.
