这是一个喇叭的测量套件测量结果(07年8月更新)
没箱子就放在桌边测的!对头吗,能说明什么问题校正曲线
阻抗
频响,远距离
晕,教程快些上吧,下午我再找个低音试试
还是梦版高,一看就知道是高音
我不懂看图,能不能有相关的教程,还有一问题,我每次测量的结果怎么都有出入,就是说每点一次测量,结果都不相同!但是测量阻抗时基本相同!能不能再讲讲,红线的蓝线的区别我的也是15欧
校正时对的那个校正电阻不一定是16欧
装套件的时候要实测一下,我的那个是15欧,校正的时候就根据实测的组织来校正。是银笛的5-14高音,呵呵
好像是8欧的,我校过了,是调到16欧吧,我把那个值改成7.5,线正好在16欧,对不对,我看你手册上说的.梦版快来看呀
顶起来,不懂图
怎样解释这些图
我接着上图,昨天晚上又调整了一下,测得的结果
给大家提供点参考!不知我测的对不对一红灯喇叭,很老的
低音阻抗

把MIC放到喇叭纸盘边测的频响

红灯的纸盆高音的阻抗

跟低音测量方法一样的频响

因我没有箱子 ,也就没上箱测量,所以频响根据梦版所说的没太大的意义
你用的应该是LSPCAD软件
LSPCAD是设计音箱不错的软件,但需要很准的喇叭单体的参数,你这样测试喇叭单体是不准确的。测试的时候请你加上障板,否则频响曲线的中低音是被抵消的.[转帖]

好像是8欧的
确实是这样,银笛的,阻抗曲线很平滑这很正常
你那又不是消音室,环境噪声与计算机的电压波动都会影响频响的一致性,我用LMS都是这样的,但LMS比较稳定,它有滤波器,所以差别不会很大不错!!!
我顶,好东东!
