用Klippel系统对扬声器频响近场测试的分析

Analysis on speaker's frequency response measured in near field with Klippel system

近年出现了一款室内条件下测试扬声器特性的Klippel系统,在普通房间里近场测试频响特性。借助一只普通的圆形扬声器,从理论基础和实际测试两个方面对扬声器进行分析对比,检验了该测试设备获得频响测试结果的可信性,并以此为基础,为选择扬声器的适用频段提供技术支持。

Recent years there is a equipment,Klippel System,to measure speaker＇s frequency response in indoor condition.This System can work in normal room to obtain speaker＇s frequency response. With a usually round speaker,the article firstly describes the related theory and then presents the speaker＇s response. By analysis and comparison,it examines the outcome reliability. Further,the result technically supports one to choose a speaker and make better use of its frequency band.
