        有源音響和無源音響的主要的區別就是在音箱內有沒有帶音頻功率放大器。從之前的專業擴聲系統案例里有提及,帶功率放大器的音響稱之為有源音響,不帶音頻功率放大器的音響就是無源音響,其實無源音響就是一個單純的音箱。
        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:
        有源的音箱是多是給電腦多媒體準備的,功率不是非常大,所以都內置了功放,當然音質也要差一些。
        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.
        有源音響常用在電腦和有線廣播中,只要系統給它一個聲音信號,就可以使它發出聲音來。但它的音質要受到聲音信號源的限制。另外,它的功率也較小,只限于家庭和個人使用。
        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.
        無源音箱:
        Passive speaker:
        無源音箱一般都是家庭影院,HIFI音箱,卡拉OK用的,需要功率放大器和信號源(VCD,DVD,CD)來一起推動的,所以音質更好。
        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.
        無源音響常用在大型的擴音中,比如較大的會場,會議室,電影,劇場及家庭影院等地方,它需要有較大的功率來推動,音質好。
        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.
