摘　　要：扬声器功率测试是电声企业对其生产的扬声器性能评估的一项重要的基本测试项目,是评判扬声器实际功率是否符合标称的额定功率的一项重要依据。文中结合业内公认的扬声器功率测试标准,介绍了扬声器功率测试的基本原理及方法,以及从硬件方面给出一种详细的具体的实现方法,并简单阐述了上位机软件的实现。The speaker power test is an important basic test project in the electro-acoustic enterprises＇ assessment of the production performance of the speakers which they produced. It is also an important basis to judge the speaker actual power that is same as the nominal rated power. This paper introduces the basic principles and methods of loudspeaker power testing which based the recognized speaker power test standard. It presents a detailed specific method from the hardware and briefly discuss on the realization of PC software as well.
