在扬声器设计过程中必需着重考虑带通信号,而不是传统的单色正弦信号。西德标准DIN45573对该信号作了详细说明,并应用于以下两个阶段,多路系统中的通道功率划分和实际应用中振幅的测定。
In the speaker design process must focus on the band pass signal, rather than the traditional monochromatic sinusoidal signal. The German standard DIN45573 specifies the signal and is used in the following two phases, channel power division in multiplex systems and determination of amplitude in practice.
