Sound system refers to the use of microphone to convert the acoustic signal of the original sound field sound into electrical signal, and then process the electrical signal through some electronic equipment according to certain requirements, and finally use the loudspeaker to convert the electrical signal into acoustic signal for playback. This whole composition from microphone to loudspeaker is the sound system. The microphone and loudspeaker are called transducers. Although the electrical signals in the sound system are different from the acoustic signals of sound waves in terms of energy form and dimension, as signals, the information between them is consistent in nature, that is, their amplitudes have a corresponding relationship of relative magnitude, and their frequencies are also corresponding. Therefore, the electrical signals in the sound system are in the sound frequency range of 20hz~20000hz in frequency, which is called audio signals. Audio signal, which is an important feature of audio system.
