爱华音响遥控器的检修
爱华音响遥控器的检修现代音频设备爱华音娴翅控拳韵渔修◎王水成爱华牌组合音响型号规格众多,一般都具备红外遥控功能,同CX—N550GHR型组合音响配套的红外遥控发射器(型号为RC—TN520EX)具有相当的代表性,该产品出厂时一律不带电路图,在有关资料上也寻觅不到,下图是本人在维修中根据发射器实物精心测试绘制而成的,现同检修实例一起奉献给读者朋友们.[故障实例一】【故障现象】该遥控发射器一贯好用,自从摔落坠地之后,全部按键都失灵,换上新电池也不见有好转.【分析与检修种遥控发射器由于控制功能繁多,故电路板匕的线路布局十分复杂紧凑,大多数元器件均采用贴片式微封装结构,而且大部分线路为印刷电路铜箔线条与印刷碳墨线条的双层布线方式,在115X45u~,的版面上竟排布着多达47个键位,线条纤细,元件密集,发射器若是受到强烈的震动或猛烈的撞击,其结构则很容易造成损伤.打开发射器外壳并取出电路板,目视检查板子上下两面的元器件和线路,重点检查质量较大,引脚较长的元件,如红外发光二极管D1,电解电容器C3,电池卡簧等.经初步检查没有发现问题,接着把电路板装回到发射器的前盖中并装上电池,找来一部中波收音机靠近发射器放置,把接收频率调至中间频段的无电台处,把音量调到较大程度,按压发射器上的的某个按键,此时从收音机中传出了”哒…..”的辐射干扰声,由此至少可以证明发射器的基准振荡部位已经启动工作,遥控失效的故障范围可能发生在驱动放大与红外发射电路之中.再次取出电路板,用外接电源对电路板供电,置500型万用表于直流电压2.5V档,把表笔并接在红外发光二极管D1的两只引脚上测其动态电压,持续按压“POWER”键,结果表针纹丝不动;顺便从D1正极对地测量电源电压,结果竟然为零,显然为电源电路出了问题.沿着D1的正极往R1方向查找,发现R1的右端(接电源正极的一端)存在正常的电压,说明问题发生在R1上.用放大镜仔细观察,发现R1本体左端的焊点上有一条微细的裂纹,此处可能已经脱开,估计是发射器摔地时被震开的. R1是贴片式电阻,体积不及半颗米粒大,故必须用30W以下的尖头电烙铁准确快速地进行焊接.补焊R1的断点后,该发射器的遥控功能恢复正常,故障排除.【故障实例二】【故障现象】以往每更换一次电池可以使用半年左右,此次更换电池不足两个月就发生遥控失灵现象. 【分析与检修】这种遥控发射器采用CNOS型红外遥控编码专用集成电路,其待机工作电流极其微小(Ⅸ0A 的待机电流仅为1左右),即使在发射状态下,整机的工作电流也不超过10mA,故非常省电,两节质量较好的普通五号电池至少也能用上半年.该发射器更换电池不足两个月就发生遥控失灵现象,说明可能产生了电源的额外消耗,或者是发射器的基准振荡频率偏离较大,实际的红外光遥控信号辐射能量不足之类的故障.取下发射器背面的电池盖板,给发射器换上两节新电池,把一块500型万用表串接在电池的回路中,为防止刚刚接通电源时较大的冲击电流对万用表的损害,这里先把档位调在直流电流500mA档,然后逐步降低档位,当换至lmA档时,待表针停稳后仍有0.6mA 的指示,而这种发射器正常的静态电流应为10p,A左右,难怪电流消耗得异常快.发射器静态工作电流过大,通常为某个元器件或某处电路漏电所致,常见的情况有电容器漏电,驱动三极管漏电,异物浸入电路板形成的漏电等.于是,小心地打开发射器的后盖,取出电路板,从外观上没有察觉到故障的迹象.本着先易后难的检修原则,首先拆下电源退耦电容器C3,再次测量发射器静态工作总电流,结果下降至l0余,问题终于水落石出.更换一只较小体积的同容量新品之后,该发射器的静态工作电流不再有额外的增加,故障排除.值得一提的是,这种组合音响配用的遥控发射器有一点与众不同,就是在电源电路电池两端并接了一只330K的贴片式电阻,尽管该电阻阻值较大,但由于发射器上未设电源开关,该电阻形成的将近l0A的电流从长期的作用效果来考虑,其功耗也是一个不小的数目.实践证明,完全可以拆除该电阻,而并不影响发射器的工作性能,电池的使用寿命无疑将会有效地得到延长.◆家用电子电爵维修2OO5.O169。

无所不拆之爱华随身听多机拆解拆机乐园
无所不拆之爱华随身听多机拆解拆机乐园悠扬的音乐,随身的MUSIC.多少人乐此而不疲,多少人为此而废色犬马.曾经年少,因为听过一台称为爱华的机器,为此沉迷,为此中毒.那清晰明快的高音,略微后缩的中音,集束炸弹一样带有轮廓的低音,一下就抓住了我的心.此后多少年,为了能够重温身历这种不同的音色,我走上了DIY败家之道.今天,我CAO*起(内含不雅词汇,系统屏蔽,真搞)手中的烙铁,准备终结这种依恋.虽然,这家公司已经变相终结有一段时间了.让我们再次怀念那个时代,那个乐曲悠扬的时代,不是双截棍式的哼哼哈嘿的时代,一去不返的时代,一个纯真年代.首先登场的是低端AIWA TA145 此机在99年北京市场零售价约200元.此机几乎可以说是爱华低端机的代表了,说他低端,倒不是说他性能差,也不是说他功能差,而是.......他省略了一极其标志性的东西:重低音提升系统!先看看外形:可以看到其基本功能为:四键全塑机芯放音系统,不带自动返带.手调式两波段收音系统,无音质调整功能 .标配2枚AA电池下号称16小时长时间放音.拆机过程:非常简单,全机只有一枚螺丝,旋去后,用无坚不摧的指甲开盖大法将其肢解.小日本的机器多使用的是ABS+PC，材质俗称ABS 加聚碳。
是国内少数几种可能透用的合料之一，不能自燃，外火燃烧时，表面有象聚碳燃烧一样的小颗粒析出，黑色低于ABS，常见于电器件、机械零配件等 .特点是比ABS轻,强度高于ABS.所以,虽然只用一枚螺丝,但结合了内侧的扣件,整机合缝性高,结构牢靠.开机后看到电路板,背面是两块集成电路,一块是28脚双列扁平贴片式封装的单片放音集成电路MM1336D，内部包含放音机所需的全部电路：双声道前置放大、功率放大及电子稳速等。
全塑机芯:显露电路面:MM1336D集成电路具有功耗小、噪声低、前置电路不用输入耦合电容、功放不用输出祸合电容，采用OCL形式的放大电路，放音输出功率强劲、动态范围宽、音乐背景清晰等特点。
爱华AIWA磁带随身听年鉴
ﻫ收放:TX,ＲX,T,RL,TA。RX是收方的轻触电控机器收音是数字,属高档机器，T是机械铁机器比较老,ＴX是一般带数字收音机，RL非常老，而且是超博的电控机器,但是收音是机械的,ＴA是非常抵挡的收方ﻫ收录放：JＸ，J，JL,JS，ＥX(只有个EX５0,ＥX300０都是针对日本的纪念）。ＪX是收录放的轻触电控机器收音一般是数字，也少的是机械的，但是都不能看到磁带,J是机械铁机心,JS是J的接班，但是只有厚机器，JL也非常老，收音机械，轻触电控,能看到带子。
198３年推出HS－P5。是一款很顶级的机器,当时世界上最轻最小的磁带随身听,使用两节7号电池。具有真实且华丽的强大解析力和浑厚有味妙不可言的音色能够轻易打败同时期的所有SONYＷALＫMＡN。几乎是那时甚至后来的大部分机型所无法比拟的梦幻机型。
19８5年推出HS-R8。其线控跟耳塞是分开设计的。是世界上第一款使用线控的随身听。
１991年推出HS-ＪX70７/70。107.5×７7×23.3mm。155ｇ。10mw。2V。使用HX磁头,3段BBE,2段ＤSL，DＯＬBY BNR,全功能线控，10分钟快速充电,三方式自动反转,磁带选择器，防滚机构，12小时播放。声音清爽干脆,犹如少女细语般清秀。是爱华经典机型。

常见功放故障维修实例
常见功放故障维修实例常见功放故障维修实例九十年代，我国进口了日本爱华（AIWA）公司生产的多种机型组合音响。
电路较为复杂，且随机无电路图纸，现大部分都到了维修期，令维修者头痛。
实际上，这些机型的电路大同小异，故障点也较为集中，只要掌握了常见故障，维修并不很难。
例1.AIWA380组合音响插电有时钟显示，但有时开机二秒钟就无任何显示，也不能进行任何操作。
检修：先检查电源12V输出，插电后时钟显示正常，些时12V输出电压为8V，开机后跌为3V，显示屏全黑，显然12V电源不正常。
查电路板，知电路板从变压器次级输出后经整流电路到调整管B1370。
测调整管基极、发射极电压在16V左右，基本正常，而集电板输出太低，说明调整管损坏。
更换后，电源12V恢复，开机能正常工作。
例2.AIWA360组合音响无屏幕显示，不能进行作何操作。
检修：直观检查电源2A保险丝断，更换后试机仍然无屏显。
测电源变压器初级220V输入正常，面输出各组电压均为0，判断为变压器坏。
拆下后，测量各绕组电阻值无明显损坏，但5 6脚之间电阻为8，说明变压器因过热而使内部熔断丝熔断。
应急修理，用细线短路5 6脚.通电后，各功能正常功放的故障维修实例Hi-Fi音响与AV放大器的常见故障有整机不工作、无声音输出、音轻、噪声大、失真、啸叫等。
下面介绍各种故障的检修思路与检修技巧。
一、整机不工作整机不工作的故障表现为通电后放大器无任何显示，各功能键均失效，也无任何声音，像未通电时一样。
检修时首先应检查电源电路。
可用万用表测量电源插头两端的直流电阻值(电源开关应接通)，正常时应有数百欧姆的电阻值。
若测得阻值偏小许多，且电源变压器严重发热，说明电源变压器的初级回路有局部短路处；若测得阻值为无穷大，应检查保险丝是否熔断、变压器初级绕组是否开路、电源线与插头之间有无断线。
有的机器增加了温度保护装置，在电源变压器的初级回路中接人了温度保险丝(通常安装在电源变压器内部，将变压器外部的绝缘纸去掉即可见到)，它损坏后也会使电源变压器初级回路开路。
通用2.1多媒体音箱电路图附讲解
工作原理，如图纸所示：主要分为三部分。
分别为电源电路、卫星箱功放电路、超重低音电路.一、电源电路（图纸的最下面部分）：220V市电经过保险管（F），和开关S后进入变压器初级，变压器的次级输出双12V交流，双12V送入由VD1组成的桥式整流电路电路，经过桥式整流和C14，C15（3300UF/25V）的滤波后，输出的空载电压约为正负16V左右（根号2乘于12V），即A+为正16V，A-为负16V。
正负16V为三块功放芯片TDA2030，UTC2030提供电源。
另一路经过R21、R22的降压后，由B+，B-输出约正负12V为低音前置放大和低通滤波器IC4提供电源电压。
在本图纸当中，前置放大的供电并没有采用78/7912三端稳压电路，磨机爱好者在更换两个3300UF电容时，也可以考虑加入LM7812/7912为前置提供更为稳定的工作电压。
二、左右声道放大电路（卫星箱功放电路），因左右声道作原理完全一致。
这里我只以图纸的左声道为例，作个介绍。
如图：RIN为信号输入端，经过耦合电容C23进入音量电位器，（音量电位器由三个引脚，与C23连接的是输入端，输出端也叫滑动端、另一引脚为接地端），调整音量后信号进入由R1/C3组成的高音提升电路，此电路可以提升一定量的高频信号，使声音更加清晰。
尔后信号经过耦合电容C1进入左声道功放，型号为UTC2030的1脚，经过功率放大后，由2030的第四脚输出，推动卫星箱发声。
图中的R7为反馈电阻，R7/R9为决定2030芯片的放大倍数。
因此，调整R7的阻值，就可以调整放大倍数。
R11/C7为扬声器补偿网络。
三、超低音电路。
由左右声道经两个10K电阻R5、R6后至C11耦合电容，尔后信号进入IC4，型号为JRC4558的3脚，图中IC4A为超低音的前置放大器。
R201T将此放大器的放大倍数设置为6倍左右。
（R17/R18），经过前置放大后，才能保证足够大的驱动电压，获得足够大的音量。
