专业音响什么的好
音箱又称扬声器箱，他是把工作在不同频段的扬声器置于专门设计的箱体内，经分频器把功率放大器的输出信号，分成高频、中频、低频信号后，分别送往各相应的扬声器进行重放的系统。音箱的种类很多，功能范围各异，分类方法也各不相同，常用的分类方法如下:
The speaker box is also called the speaker box. It places the speakers working in different frequency bands in the specially designed box body. The output signal of the power amplifier is divided into high frequency, medium frequency and low frequency signals through the frequency divider, and then sent to the corresponding speaker system for replay. There are many kinds of speakers with different functions and different classification methods. The commonly used classification methods are as follows:
一、按用途分:落地式音箱、有源音箱、环绕音箱、书架式音箱、**音箱。按工作频率分:超低音音箱、多分频音箱、2分频音箱、3分频音箱。按内部结构分:密封式音箱、倒相式音箱、空纸盆式音箱、对称驱动式音箱、迷宫式音箱、哑铃式音箱。下面就常用的音箱进行介绍:
1. By use: floor type speaker, active speaker, surround speaker, bookshelf type speaker and ** speaker. According to working frequency: Ultra-bass speaker, multi-frequency speaker, 2-frequency speaker, 3-frequency speaker. According to the internal structure: sealed speaker, inverted speaker, empty carton speaker, symmetrical drive speaker, labyrinth speaker, dumbbell speaker. Following is an introduction to the commonly used speakers:
(1)密封式音箱结构 结构如图155(a)所示。它是由箱体、扬声器、吸音材料构成。音箱后面是密封的，前面留有扬声器口，它将扬声器安装在一个完全封羽的箱体中，箱体的声音基本上被封罚，把扬声器前、后的声波给隔开。
(1) The structure of the sealed speaker is shown in Fig. 155 (a). It is composed of box, speaker and sound absorbing material. The speaker is sealed behind the speaker and has a speaker mouth in front. It installs the speaker in a fully feathered box. The sound of the box body is basically sealed off and the sound waves before and after the speaker are separated.
特点 具有较好的低频响应、重放低音深沉，又由于音箱是全封闭(除扬声器外)，故防止了声短路现象。但该种音箱内的空气有阻尼作用，影响了音箱的共振频率和品质因数。又由于音箱内的吸音材料，消耗掉部分声能，所以密封式音箱的灵敏度较低。
It is characterized by good low frequency response, deep repetition of bass, and the sound short circuit is prevented because the speaker is totally enclosed (except the loudspeaker). But the air in the speaker has damping effect, which affects the resonance frequency and quality factor of the speaker. Because the sound absorbing material in the speaker consumes part of the sound energy, the sensitivity of the sealed speaker is low.
