音响产品的输出功率是衡量音响产品性能优劣的一项最基本的技术指标。包括收音机、录音机、扩音机等在内的音响产品,都必须要标注明它的数值大小。然而输出功率有额定输出功率、最大不失真功率和音乐功率等多种表示方法。因此,弄清楚是何种输出功率及其物理含义具有一定的实际意义。为便于说明这一问题,先须简要了解一下音乐信 The output power of audio products is a measure of the pros and cons of audio products, a basic technical indicators. Including radio, tape recorders, amplifiers and other audio products, must be marked with its numerical size. However, the output power has a rated output power, maximum distortion power and music power and other means of expression. Therefore, it is of practical significance to clarify what kind of output power and its physical meaning. In order to explain this problem, we must briefly understand the music letter
