有源音响和无源音响的主要的区别就是在音箱内有没有带音频功率放大器。从之前的扩声系统案例里有提及,带功率放大器的音响称之为有源音响,不带音频功率放大器的音响就是无源音响,其实无源音响就是一个单纯的音箱。
The main difference between active audio and passive audio is whether there is an audio power amplifier in the speaker. As mentioned in the previous case of professional sound reinforcement system, the sound with power amplifier is called active sound, and the sound without audio power amplifier is passive sound. In fact, passive sound is a simple speaker.
有源音箱:
Active speaker:
有源的音箱是多是给电脑多媒体准备的,功率不是非常大,所以都内置了功放,当然音质也要差一些。
Most of the active speakers are for computer multimedia, and the power is not very large, so they all have built-in amplifiers. Of course, the sound quality is also poor.
有源音响常用在电脑和有线广播中,只要系统给它一个声音信号,就可以使它发出声音来。但它的音质要受到声音信号源的限制。另外,它的功率也较小,只限于家庭和个人使用。
Active audio is often used in computer and cable broadcasting, as long as the system gives it a sound signal, it can make it sound. But its sound quality is limited by the sound signal source. In addition, its power is also small, which is limited to family and personal use.
无源音箱:
Passive speaker:
无源音箱一般都是家庭影院,贬滨贵滨音箱,卡拉翱碍用的,需要功率放大器和信号源(痴颁顿,顿痴顿,颁顿)来一起推动的,所以音质更好。
Passive speakers are generally used in home theater, hifi speakers and karaoke. They need power amplifier and signal source (VCD, DVD, CD) to drive together, so the sound quality is better.
无源音响常用在大型的扩音中,比如较大的会场,会议室,电影,剧场及家庭影院等地方,它需要有较大的功率来推动,音质好。
Passive audio is often used in large-scale amplifying, such as large venues, conference rooms, movies, theaters and home theaters. It needs a large power to drive and has good sound quality.
