FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -A microphone is a device that translates sound vibrations in the air into electronic signals and scribes them to a recording medium or over a loudspeaker. Microphones enable many types of audio recording devices for purposes including communications of many kinds, as well as music vocals, speech and sound recording.

Detailed explanation-2: -The function of a microphone in a computer is to pick up sound, just like a microphone used by a singer on stage, and convert the audio sound waves into electrical signals. From there, these electrical signals travel to the sound card, where they are converted into digital signals, able to be processed by the computer.

Detailed explanation-3: -The magnetic field created by current flowing through the voice coil interacts with the magnetic field of the speaker’s magnet, forcing the coil and attached cone to move back and forth, producing sound output. A dynamic microphone operates like a speaker in reverse. The diaphragm is moved by changing sound pressure.

Detailed explanation-4: -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, and radio and television broadcasting.

Detailed explanation-5: -Just like we use our diaphragms to sing, microphones use their diaphragms to pick up sounds and convert them into electrical currents. A microphone converts sound into a small electrical current. Sound waves hit a diaphragm that vibrates, moving a magnet near a coil. In some designs, the coil moves within a magnet.
