众所周知,功放与扬声器系统的配接是放声(扩声)系统中最重要的一个环节,功放是扬声器系统的功率源,扬声器系统是功放的负载,属音频功率传输,其功率传输效率是首要追求的,它与功放输出电路自身的输出参数及扬声器负载的特性密切相关,这是功放输出电路设计的一个重要环节。功放输 As we all know, the amplifier and the speaker system is the sound (sound reinforcement) system is the most important part of the amplifier is the speaker system power source, the speaker system is the power amplifier load, is an audio power transmission, the power transmission efficiency is the primary pursuit , Which is closely related to the output parameters of the amplifier output circuit and the characteristics of the speaker load, which is an important part of the design of the amplifier output circuit.
