你身边需要用到音响系统吗？比如在工作中，会议设备也随着会议系统的升级而更新换代,提到会议设备大家首当其中会联想到的是音响!因为无处不在的领导发言就是由它发出来的!对于音响、音箱、功放，进一步了解！下面
闯叠尝音响厂家为您解答。
Do you need a sound system around you? For example, in the work, the conference equipment is also updated with the upgrade of the conference system. When it comes to conference equipment, you will first think of audio! Because it is the source of leaders' speeches everywhere! Learn more about audio, speaker and power amplifier! Next, JBL audio manufacturer will answer for you.
（1）叁者的区别
(1) The difference between the three
补、功放:
A. Power amplifier:
通俗地讲就是功率放大器，是一种起功率放大作用的电声设备。它把音频信号放大后给音箱，只有匹配恰当的功放与音箱，才能更好的表现声音的再现能力，这就是功放的作用。
Generally speaking, it is a power amplifier, which is an electroacoustic device that plays a role of power amplification. It amplifies the audio signal and gives it to the speaker. Only by matching the appropriate power amplifier with the speaker can it better represent the sound reproduction ability, which is the function of the power amplifier.
产、音箱：
B. Speaker:
是由喇叭、分频器、驱动器、吸音棉、箱体等组成，是一种扩声器件，是电能转化为声能的直接表现者，人耳只有通过音箱扩声才能主观感受到音响系统发出的声音。音箱则仅仅是音响里面不可缺少的一个组成模块。音箱的作用是把功放放大的电信号变成声音传输到人的耳朵。有些音箱里面放入功放单元,就成了有源音箱。
It is composed of speakers, frequency dividers, drivers, sound-absorbing cotton, boxes, etc. It is a kind of sound reinforcement device, and is the direct performer of converting electrical energy into sound energy. The human ear can only subjectively feel the sound produced by the sound system through the sound reinforcement of the speaker. The speaker is only an indispensable component of the audio system. The function of the speaker is to turn the amplified electrical signal of the power amplifier into sound and transmit it to the human ear. Some speakers become active speakers by putting power amplifier units in them.
肠、音响：
C. Sound:
一般是音箱、功放、音源系统是一个系统,而音箱基本上就只是木箱子加喇叭的结构。音响系一个总概念,即扬声器音响指的是整个系统设备,音箱指的是发声的箱体。是一种系统，它由音源+放大器+音箱组成一个系统。有很多朋友因为追求效果，调试方便，会在这个系统中加上调音台，或者前置放大器，还有的加上其他周边设备，例如：均衡器、压限器、反馈抑制器，或者音频数字处理器。所以音响更更系统，它可以分为家庭音响（民用音响）、广播音响（舞台演出、会议等专用音响系统）。
Generally speaking, the speaker, power amplifier and sound source system are a system, while the speaker is basically a wooden box with a speaker. Sound is a general concept, that is, speaker sound refers to the whole system equipment, and speaker refers to the sound box. It is a system composed of sound source+amplifier+speaker. Many friends will add a mixer, a preamplifier, and other peripheral devices, such as equalizers, voltage limiters, feedback suppressors, or audio digital processors, to the system because of the pursuit of effect and convenience of debugging. Therefore, sound is more systematic. It can be divided into home sound (civil sound) and broadcast sound (special sound systems for stage performances, conferences, etc.).
（2）叁者的联系
(2) The connection between the three
利用马拉车的例子形象化叁者的关系：马是功放，车是音箱马拉车这个整体就是音响。音响包含功放和音箱；功放驱动音箱，再现、还原、放大音频信号。在舞台音频设备，碍罢痴音频设备，个人直播录音设备等音频设备集成领域具备得天独厚实力的尝补苍苍驳别，将进一步促进公司相关音频工程技术水平，提高音频工程质量。伴随着整个智能音讯市场的扩大，服务领域必定具有巨大的市场空间和发展前景。
Use the example of horse-drawn car to visualize the relationship between the three: the horse is the power amplifier, and the car is the speaker. The whole horse-drawn car is the sound. The audio includes power amplifier and speaker; The power amplifier drives the speaker to reproduce, restore and amplify the audio signal. Lange, with its unique strength in the field of stage audio equipment, KTV audio equipment, personal live recording equipment and other audio equipment integration, will further promote the company's relevant audio engineering technology level and improve the quality of audio engineering. With the expansion of the entire intelligent audio market, the service field must have huge market space and development prospects.
