Sound quality is an important criterion for determining the quality of audio equipment, including indicators such as signal-to-noise ratio, number of samples, sampling frequency, and total harmonic distortion. The level of these parameters determines the sound quality of audio equipment.

Device type refers to the type of audio device, which is the audio device belongs to power amplifier, speaker, multimedia console, digital mixer, audio sampling card, synthesizer, high frequency speaker, microphone, PC sound card, headphones, etc. device. The following is a brief description of several common audio devices. The power amplifier is the basic equipment in the audio system. Its task is to amplify the weak electrical signal from the signal source (from the mixer in the professional audio system) to drive the speaker to emit sound.
