1.外观篇
这个东东是用一个装旦卷的铁皮盒子改装的,原来是金色的,我将商标部分和大部分喷了银色,保留小许金色
正面

2。构造篇
打开盖子,由于机箱的体积太小,原来打算用的环牛电压过高,导致发热量太大,换了一个EI牛,但体积较原来的高,就将功放板翻过来放了,,呵呵,好在,,刚好能放进去
<img src="attachments/dvbbs/2005-3/2005324123332502.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-3/2005324123332502.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
这是用5块1875和洞洞板做的后级功放板,用了个P4的散热器从中间锯开两个声道一半,中间声道的自己用半块散热片

前级部分,,用NE5532做前级放大和高低音调节,因为有5个声道输入,我做了两个一样的前级,中间声道的就用一块5532做放大,没有调节,前面声道和后面声道的两块板子叠了起来,像一个小架子,呵呵,,因为装起来了就没有拍到图片
<img src="attachments/dvbbs/2005-3/2005324124222250.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-3/2005324124222250.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
图上隐约可以看到上下有两块板的

这是中置声道的前级
电源部分是我比较头痛的,原来的不小心,以为1875可以用双35V的电压,用了个环牛,而且设计的电源滤波整流都是按照牛来装的,装好后发觉发热太大,就算没信号输入都很热,没办法,上论坛请教高手后发现原来是电压搞错了,刚好手头有个双12V的EI牛,就先用着吧,但那个Ei太高了,功放板放不进,不得已就翻过来放
<img src="attachments/dvbbs/2005-3/2005324124958865.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-3/2005324124958865.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />

滤波整流板,以前在陶街淘了两个33000uF25V的电容,上面居然只是用纸贴上的标签,连正负极都没有标的,但看做工都挺不错,不像流野,呵呵,,回来用上,感觉还可以
<img src="attachments/dvbbs/2005-3/2005324125719427.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-3/2005324125719427.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
信号输入部分,因为本人比较喜欢听收音机,或者单独开CD机听CD,希望这个功放的主声道能有3个信号源选择,就用了一个4017和三个继电器做单键3路音频输入,继电器是在某个猫上拆下来的,呵呵,好像品质还可以,小日本的东西
<img src="attachments/dvbbs/2005-3/2005324125825401.jpg" border="0" onload="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onmouseover="if(this.width>screen.width*0.7) {this.resized=true; this.width=screen.width*0.7; this.style.cursor=\'hand\'; this.alt=\'Click here to open new window\nCTRL+Mouse wheel to zoom in/out\';}" onclick="if(!this.resized) {return true;} else {window.open(\'attachments/dvbbs/2005-3/2005324125825401.jpg\');}" onmousewheel="return imgzoom(this);" alt="" />
这个就算三个led指示不同的输入源

可以看到前面板有输入指示和一个轻触开关

小结
还有低音通道我没有做功放,是考虑到功率需要比较大的,这个小盒子装不下,打算整合到低音炮里面去了,我只是做了个放大和音量调节给低音输出通道。
小结:这个东东本来只是我用来增强自己电脑的5。1声道的效果,用来玩游戏和看DVDrip时候小爽一下的。呵呵,自从上了这个论坛后自己学多了不少知识,并不断改进自己的DIY水平。本来这里高手云集,小弟把这东东献出来实在是献丑了,没有用什么发烧的配件,没有做pcb板,所有东西都是以最大的DIy来diy的,哈哈。总之,虽然听起来不能和其他音响媲美,但自己听着还不错的,总之能发挥了他的最大用处,而且是自己做的,我就很心足了。
