摘要
目前国内大多数扬声器电声参数测试系统以模拟仪器为主,而且其价格昂贵、使用条件相对苛刻、检测参数项较少、检测时间长。研制了一种基于计算机的扬声器电声参数自动测试系统。开发数字算法快速处理发声体参数,对采集的数据快速处理,准确检测定位两接线端子的位置。该系统有良好的人机交互界面和测试功能,能够在较短的时间内自动检测扬声器的灵敏度频响曲线、失真频响曲线、相位频响曲线等各项电声参数。系统可应用于扬声器的电声性能检测。
At present, most speakers electro-acoustic parameters of the test system mainly with analog instruments, the deficiency of its high price, the use of harsh conditions, the detection parameters, the long detection time, and so on is considered, a speaker electro-acoustic parameters automatic test system based on computer is developed. The digital algorithms quickly process parameters sounding body is useed to rapidly process of the collected data accurately , detect the position of the two terminals positioning, the system has good manmachine interface and test functions, which can be used in a short period of time automatic detection sensitivity frequency speaker response curve, the frequency response curve distortion, phase response curve and other electro-acoustic parameters. The system can be used in electro-acoustic performance testing speakers.
