Beilarly stage audio literacy stickers: Sound and speakers are not clear?

In life, there are always people who confuse sound with speakers. In fact, sound is a system consisting of sound source, microphone, front stage, back stage and terminal load. Speakers are only the terminal load part. It can be seen from the components of the sound system - sound source (VOD, CD, Blu ray machine, etc.), microphone, front stage (front stage or mixer stage of k-song's effector), rear stage (power amplifier power amplification module), speaker, any component is indispensable. Therefore, sound source, microphone, front stage, back stage and speaker can be called sound components, not sound. So it's not professional to call a speaker a sound.

The speaker is simply composed of a wooden box, two or several speaker units plus several capacitors, resistors and inductors. But it is "easy to sound but difficult to refine", the most critical part of the voice. There are many kinds. It can be roughly divided into two categories: professional and civil. The civil speakers refer to the general household small combined speakers, multimedia active combined speakers, advanced household hifi speakers and square dance speakers, etc. the professional speakers can be divided into professional stage speakers, KTV speakers, etc.

Although the speaker is not equal to the sound, but in the sound system, the speaker is the final load component, which is very important. Therefore, the sound quality and timbre are basically determined by the level, performance and quality of the speaker. The stability and durability of the sound system are also closely related to the power, performance and quality of the speaker.
