耳机功率放大器是一种放大器,因为比较大的耳机阻抗很高,小的随身听是带不起来,推不动,就要耳放,有源的,接在音源和耳机中间。

The earphone power amplifier is a kind of amplifier. Because the impedance of the relatively large earphone is very high, the small Walkman can’t be carried. If it can’t be pushed, it needs an earphone. The active one is connected between the sound source and the earphone.

产品分类

Product classification

在高端的耳机中分为两类,一种是高阻抗、低灵敏度的耳机,这类的耳机普通设备的耳机输出很难驱动。还有一类的耳机采用的低阻抗、高灵敏度的设计,这样的耳机对于电流输出的稳定性要求很高。针对这种情况,需要耳放来改善音源的耳机输出,来发挥耳机的效果。

There are two kinds of high-end earphones. One is high impedance and low sensitivity earphones. It is difficult to drive the output of ordinary devices. There is also a kind of earphone with low impedance and high sensitivity, which requires high stability of current output. In view of this situation, it is necessary to improve the earphone output of sound source to play the effect of earphone.

适用范围

Scope of application

从体积上来分,耳放可以分为台式耳放,这种耳放一般体积较大,适合在家庭中使用。还有一种为便携耳放,体积小巧,可以和随身设备搭配。从使用的主要元器件,也可以分为胆机(电子管)和石机(晶体管)两种,声音趋向各不相同。在实际的使用中,根据自己的耳机耳塞添加合适的耳放设备,效果提升是十分明显的。

From the volume point of view, the earphone can be divided into desktop earphone. This kind of earphone is generally large in size and suitable for use in the family. There is also a portable earphone, small size, can be used with portable equipment. From the use of the main components, can also be divided into gall machine (electronic tube) and stone machine (transistor) two, the sound trend is different. In the actual use, according to their own earphone earplug add appropriate earphone equipment, the effect is very obvious.
