扬声器的功率是扬声器最为重要的指标。在音响工程设计，扬声器与放大器之间功率匹配等设计过程中，都必须清楚地知道扬声器的功率数值及其含义。目前各国不同厂家在扬声器的铭牌上所标的功率值，其含义往往各不相同，因而数值上往往有很大出入。 近年我国已统一制订了扬声器功
The speaker’s power is the most important indicator of the speaker. In the audio engineering design, speaker and amplifier power matching between the design process, we must clearly know the speaker power value and its meaning. Currently different countries manufacturers in the speaker nameplate on the power value, the meaning is often different, so the value is often very different. In recent years, China has formulated a unified loudspeaker system
