在多媒体音箱领域，独 立功放的概念出现于2002年，经过一段时间的市场培育后，大约在2005和2006年，这种多媒体音箱的全新设计思路已经得到了消费者的广泛认同，各大音箱厂商也纷纷推出了采用独 立功放设计的新型2.1音箱，从而掀起了一波又一波“独 立功放”的热潮。其实从音箱音质方面讲，并不会因为独 立功放的设计获得大幅的提升，独 立功放只是可以有用减少电磁干扰对音质的影响，并不足以引起音质的可观提升。尽管如此，独 立功放设计依然拥有普通2.1多媒体音箱所不具备的诸多优点：
In the field of multimedia speakers, the concept of independent power amplifier appeared in 2002. After a period of market cultivation, about 2005 and 2006, this new design idea of multimedia speakers has been widely recognized by consumers. Major speaker manufacturers have also launched new 2.1 speakers with independent power amplifier design, Thus set off a wave after wave of "independent power amplifier" boom. In fact, the sound quality of the speaker will not be greatly improved because of the design of the independent power amplifier. The independent power amplifier can only effectively reduce the impact of electromagnetic interference on the sound quality, which is not enough to cause a considerable improvement in the sound quality. However, the design of independent power amplifier still has many advantages that ordinary 2.1 multimedia speakers do not have
，独 立功放由于没有内置的体积，所以可以做到更好的散热效果。普通的内置功放的音箱，由于被密封在导热效果差的木箱箱体内，只能通过倒相管的对流进行散热。
First of all, the independent power amplifier has no built-in volume, so it can achieve better cooling effect. Because the ordinary speaker with built-in power amplifier is sealed in the wooden box with poor heat conduction effect, it can only dissipate heat through the convection of phase inversion tube.
而对于独 立功放来说，虽然功放电路同样被封在盒子里，但由于功放盒不像音箱，没有密封的要求，所以可以在发热部件的位置开出大量的散热孔，使得热量可以通过自然对流迅速的发散出去。这对于大功率功放尤为重要。
For the independent power amplifier, although the power amplifier circuit is also sealed in the box, because the power amplifier box is not like a speaker, there is no sealing requirement, so a large number of heat dissipation holes can be opened at the position of the heating parts, so that the heat can be rapidly dissipated through natural convection. This is particularly important for high power amplifier.
其次，从功放这一方面来说，独 立功放对于电路的设计有利。普通的音箱为了容积、稳定性等诸多因素，电路的设计非常紧凑，很难做到优化的电路排布。
Secondly, from the aspect of power amplifier, independent power amplifier is beneficial to the design of the circuit. For the sake of volume, stability and many other factors, the circuit design of ordinary speakers is very compact, so it is difficult to optimize the circuit layout.
而独 立功放，由于具备了独 立的功放盒，具有充足的空间，所以电路设计上可以一切从电学设计的需要出发，而不受客观因素的干扰。独 立功放对于电路的稳定发挥有利。
The independent power amplifier, because of the independent power amplifier box, has sufficient space, so the circuit design can start from the needs of electrical design, without the interference of objective factors. Independent power amplifier is beneficial to the stability of the circuit.
再次，内置功放的音箱，由于箱体内的空气处于不停止的振动之中，导致功放的笔颁叠版和电子元件发生谐振，而电容等元件的振动会回放到声音中去，从而出现杂音。
Thirdly, because the air in the speaker with the built-in power amplifier is in the constant vibration, the PCB board and electronic components of the power amplifier will resonate, while the vibration of the capacitor and other components will play back to the sound, resulting in noise.
另外扬声器也会产生电磁上的影响，即使是全防磁的喇叭，也会又不可避免的漏磁现象，硕大的低音喇叭更是如此。电路版、滨颁等电子元件售漏磁的影响，会对电路中的电流产生干扰，从而产生干扰的电流声。
In addition, loudspeakers will also have electromagnetic effects. Even if the loudspeakers are fully antimagnetic, there will be inevitable magnetic leakage, especially for the huge bass loudspeakers. The influence of magnetic flux leakage of circuit board, IC and other electronic components will interfere with the current in the circuit, resulting in interference current sound.
此外，独 立功放设计的音箱由于采用了功放箱体控制的方式，很大程度地解放了低音箱的摆放位置，节省了宝贵的桌面空间。
In addition, the speaker with independent power amplifier design adopts the way of power amplifier box control, which largely liberates the placement of low speaker and saves valuable desktop space.
说了这么多独 立功放的优点，其实总结出来就是一句话——如果不考虑体积、价位等等原因，只从使用效果角度考虑的话，那么独 立功放要优于内置功放的设计。
After talking about the advantages of so many independent power amplifiers, it can be summed up in one sentence: if we don't consider the size, price and other reasons, and only consider the use effect, then the independent power amplifier is better than the built-in power amplifier.
