The speaker is the terminal of the entire sound system, and its function is to convert audio energy into corresponding sound energy and radiate it to the space. It is an extremely important part of the sound system, because it is responsible for the key task of converting electrical signals into acoustic signals for human ears to listen directly to. It has to directly deal with human hearing, which is very sensitive. And has a strong ability to distinguish the timbre of complex sounds. Since the human ear’s subjective perception of sound is the most important criterion for evaluating the sound quality of an audio system, it can be considered that the performance of speakers plays a key role in the playback quality of an audio system.
