How much do you know about audio and speakers

　　In recent years, the number of singer talent shows in China has gradually increased, and the shows have been loved by the audience. When we appreciate the wonderful singing, we must not ignore our "behind the scenes staff" - professional speakers and professional audio that are necessary for stage performances. It is they have been working silently behind the scenes for us to hear high-quality sound quality. So how much do you know about them that have been silently dedicated?

　　Speakers and speakers are separated by only one word, and the pronunciation is very similar, but do you know how to distinguish these two twins? It's just a structure of a wooden box and speakers. The sound system is a general concept, and the speaker system is a box, that is, the speaker.

　　Audio refers to the entire system equipment, and speakers refer to the box that emits sound. Audio: generally refers to the entire audio and video system; speakers: refers to the audio output device. In layman's terms: audio is generally a speaker + power amplifier + sound source system, which is a system, and the speaker is basically just a structure of a wooden box and a speaker. The sound system is a general concept. The speaker is a box, that is, the speaker. The sound refers to the entire system equipment, and the speaker refers to the sound box.

　　How do we distinguish between speakers and audio twins with such similar pronunciations? The identification method is as follows:

　　One: look at the structure of the two

　　The speaker is the terminal of the entire sound system, and its function is to convert the audio energy into the 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 sound signals for human ears to hear directly. It has to deal directly with human hearing, and human hearing is very sensitive. And it 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 a sound system, it can be considered that the performance of the speaker plays a key role in the playback quality of a sound system.

　　Two: distinguish the sound quality of the two:

　　To be more specific: the sound, as the name suggests, can play and be loud. Therefore, from this point of view, the audio should include audio sources, power amplifiers, and speakers. The sound forms are different, there are integrated, split, and some auxiliary equipment is added in the middle, such as tuner, equalizer and so on. The ultimate goal is to restore the real sound.
