The mic hole is the jack for the microphone. mic is abbreviated from Microphone, meaning microphone, its scientific name is microphone. mic is an energy conversion device that converts sound signals into electrical signals, commonly known as a microphone.
The microphone is an unusual piece of music equipment. In essence, it is not a \"musical instrument\
The history of the microphone dates back to the late 19th century, when several scientists worked to find a better way to pick up sound, which could be used to improve the latest invention of the time, the telephone.
microphone jack
microphone, the scientific name is microphone, from the English microphone (microphone) translation, referred to as mic, also refers to the mic jack, that is, the microphone jack, also known as microphone, microphone. A microphone is an energy conversion device that converts sound signals into electrical signals. The categories are moving-coil, capacitive, electret and recently emerging silicon micromicrophones, in addition to liquid microphones and laser microphones. Most microphones are electret capacitor microphones, which work by using a vibrating film of polymeric material with permanent charge isolation.
The working principle of the loop microphone is that the human voice vibrates the shock film through the air, and then the magnetic field is cut between the electromagnetic coil winding on the shock film and the magnet surrounding the moving coil microphone head, forming a weak fluctuating current. The current is sent to the loudspeaker, and the fluctuating current is turned into sound in the opposite process.
