【摘要】 通常在扬声器的特性分析中,它的相位特性是不考虑的,但作为一个系统来说,相位特性应是系统的特性之一。特别是线性系统,相位响应有其严格的定义和意义。因此,本文把扬声器作为线性系统来处理作为一例,详细地论述了扬声器的相位响应定义及其意义,对扬声器单元给出了相位响应和频率响应之间的相互关系式,并和实际测量进行了比较,最后,本文给出相位响应在组合音箱设计、与频器使用等方面的应用。更多还原

【Abstract】 In the analysis of ordinary loudspeaker, its phase characteristics isn’t considered. However, Phase characteristics is one of the features of loudspeaker. Its phase response has strict definition and meaning especially for linear system. Therefore, taking the loudspeaker as a linear system, we discuss the definition of loudspeaker phase response and its meaning in detail. The relation between loudspeaker’s phase response and frequency response is given,then it is compared with the results of practical measurement. Finally, the applications of the phase response to the design of loudspeaker system and use of crossover network are given in the paper.更多还原
