本菜鸟DIY音响的历史,可以追诉到1998年的初春。当时在南京刚参加工作,业余时间无以打发,看到《无线电》上有喇叭邮购的信息,于是萌生了做一对音箱念头。
那时候什么都不懂,以为音箱无非是箱体+喇叭+分频器的组合。跑到江苏电子城乱逛(在山西路那里,不知现在拆了没有),正好看到一家卖南鲸的柜台,隔壁还有卖空箱体和吸音棉的,买了两对南鲸喇叭,低音200-8XPH(135元/只),高音DT506FS(好像每只50元)。8XPH的等效容积23L,于是又以180元买了一对20L左右的空箱体,再加上分频器,这对箱子总花费600元左右。在我的单身宿舍里,听着自己制造的轰鸣声,心里那个美呀... ...那时候,从来不知道这对箱子完全搞错了。
后来来到上海发展,用了4、5年的时间算是站住了脚跟,所谓温饱思XX,DIY音箱的想法再次冒了出来。不过,此时对音箱制作的基本知识有所长进,看了不少资料和制作的书籍,因为在上海,喇叭就决定用银笛的(方便购买)。买来YD176-560X和8-1,按照厂家的数据计算出箱体的容积,再用软件模拟好长宽高尺寸,同样使用厂家的数据设计分频器。做箱体,绕电感,装箱,试听,效果很不错的说:),后来又用142-1506X-S+5-34做了环绕音箱、电脑音箱,至此,我的第二次音箱DIY到此告一段落。
很显然,用厂家的标准数据设计音箱,其最终结果并不准确,甚至偏差很大。但苦于自己不会测量,更没有测量器材工具,所以只好带着这份遗憾囫囵的听了大半年。
前段时间开始接触我们HiFIDIY论坛,得知梦游版主和小钳子版主设计组织了音箱测量套件的团购,梦游版主更是制作了使用教程,心中狂喜,第一时间汇款给小钳子定了一套(第一波团购因为不知道,没赶上),3天后东西到了,用了4个晚上+1个白天安装好,调试,试测,一切OK。心里别提多高兴了,有了这套测量工具,从此,我的音箱DIY也算进入了“准”“专业”的阶段了,呵呵:),在此,要感谢梦游和小钳子对DIYer的贡献。
由于个人对测量的重视,所以这个套件的安装过程很仔细,特别买了机壳,布局、连线等也颇动了一番脑筋,在这里把图呈上来,供其他朋友指正参考。

内部图1:右面是功放部分,从散热器和变压器间穿过的两根黄色线分别是双交流15V电源线和整流后去话放的+直流电,黑色线是功放的OUT。

内部图2:右侧是话放部分,上面两根鼓起的是屏蔽线(用扎带捆在一起,分别是MIC输入插座到话放的输入 和 Line-In电位器到功放的输入。

内部图3:功放电源整流的 负端和地端分别接了双股排线的两个头,这是借功放的负电部分接到指示灯的,LED串了一个4.7K电阻。左上角的插座是带保险丝和开关的一体化插座(4元?),上有个蓝色的东东,是电容,接在开关两端,防止打火。

装好的正面图:20元买来的塑料壳。指示标签条的做法:先对照面板各插座和开关的位置打印好,然后在文字上贴一层透明胶带(防褪色、防水),用刀片划去多余的部分,再用双面胶贴在面板上。

Probe线,接喇叭
做Mic探头的时候费了不少脑细胞,因为找不到合适的东东做外壳。后来灵机一动,拆了一只水笔,剪断一根VCD的视频线,用尸体做了一个探头:)

只是电阻校准的图,我的电阻数字万用表打出来是15欧的。
为什么我的校准曲线有这么多锯齿?是电阻稳定性有问题还是声卡不好?或者声卡距离CPU风扇太近受到干扰?
