摘要
介绍美国DRA实验室研制的基于最长序列MLS信号测试技术的扬声器电声分析系统MLSSA。同时给出对其进行自动化改造的思路及方法,经改造后该系统能适应扬声器工厂生产线大批量测试产品频率响应的需要。对扬声器生产工厂的质量控制有一定意义。
A brief introduction to MLSSA(Maximum-Length Sequence System Analyzer)is presented,which is developed over the MLS signal theory by DRA laboratories,U.S.A.A method is also given to reconstruct the system in order to use it to test loudspeakers quickly for manufacturer's mass-produc-tion.The reconstructed system is of certain benefit to manufactarer's quality control.[
