火凤凰汽车音响评分
火鳳凰汽车音响评分作为一名拥有近20年汽车音响从业经验的汽车音响发烧友，火凤凰汽车音响评测中心的车友对于汽车音响的了解往往不会局限于汽车音响本身，而是更多的是会把音乐放在他们的首位，对于汽车音响的改装更是不遗余力。
我也是在看到改装后音响改装效果很好后才决定去改装一辆这样功能完善而且性价比较高、改装空间也较大的车。
就这样我被这辆音响改装成了一辆能聆听音乐到深夜的家庭影院车。
这套音响配置为三分频设计、声音定位精准、动态表现细腻、性价比高，为我的爱车打造了一款高品质影院级音乐享受车。
目前我个人最喜欢的一套音乐曲目是 JBL音乐录音棚版的《DUBO》、《Music Time》和《Reverse Temperature》。
这套音响由 JBL公司设计并打造而成。
整个音响配置非常简单、实用。
1、前声场三分频: JBL天籁X1,定位精准JBL天籁X1的前声场三分频是一款有着很高性价比和非常优秀音响音质的音响。
采用三声道无损安装，喇叭安装在后备箱下方的位置，前后声道分离。
后声场中置采用倒相式设计，声音定位精准。
前声道喇叭安装在前门板下方位置，后声场中置扬声器安装在尾箱下侧位置，这样整个前声场定位更加的精准和自然。
JBL天籁X1作为一款主打家庭影院音质的音响系统，拥有很好的性价比优势。
所以对整个配置不太要求太高，只要有钱就可以完成升级需求。
JBL天籁X1在声场喇叭和低频喇叭采用了双中置低音设计与一体双球顶高音单元之间用橡胶密封圈固定好关系。
可以实现360°环绕输出声音。
能够提供更稳定、更高品质的声音表达效果，也能有效降低失真现象出现。
2、中低音单元：美声魔贝Q7在改装音响时，第一步就是更换美声魔贝Q7的中低音单元，也就是低音单元部分。
这款单元采用全铝制一体成型焊接、铝合金箱体构造，表面采用哑光质感处理，配合铝制箱体结构抗氧化和耐腐蚀，抗冲击能力强、耐热性能好，耐冲击能力强、不开裂。
同时还能增加低音量感和下潜，增强低频下潜力度和深度。

AS SUCH, PROPER CARE AND ATTENTION TO DETAIL WHEN SETTING UP THESE SPEAKERS WILL YIELD THE MAXIMUM PERFORMANCE, REGARDLESS OF THE PARTICULAR ROOM. FOLLOWING THESE SET-UP GUIDELINES WILL ENSURE THE SPEAKERS ARE PROPERLY POSITIONED TO DELIVER THE OPTIMUM LISTENING EXPERIENCE. ALL THAT IS REQUIRED IS A TAPE MEASURE, A PEN, A CALCULATOR, A BALL OF STRING, A COUPLE OF DEMO CDS, AND SOME PATIENCE.PLACEMENT—S1MKIIS IN RELATION TO BACK AND SIDE WALLSBEFORE YOU BEGIN: LOOK FOR OBVIOUS IMPEDIMENTS INCLUDING ANYTHING THAT COULD IMPEDE OR DIMINISH THE SOUND—E.G., OTHER SPEAKERS, AMPLIFIERS, EQUIPMENT RACKS, ANYTHING ON THE WALL THAT COULD CAUSE A REFLECTION, A SEVERE MISMATCH IN QUALITY AMONG INDIVIDUAL COMPONENTS, AND UNNECESSARY OR POORLY RUN SPEAKER/INTERCONNECT CABLES.BASS—DISTANCE FROM REAR WALLTHE INITIAL PLACEMENT SHOULD BE APPROXIMATELY 20 INCHES (1/2 M) FROM THE BACK OF THE LOUDSPEAKER TO THE BACK WALL. SINCE WE HAVE SHORT AUDITORY MEMORY, THE SELECTED DEMO MUSIC CUT SHOULD BE BRIEF—30 SECONDS – 1 MINUTE MAX. IT SHOULD BE A WELL RECORDED JAZZ CUT WITH GOOD BASS GUITAR OR PERCUSSION. WHAT WE ARE LISTENING FOR AT THIS TIME IS THE DEFINITION OF THE BASS AND THE RIGHT SENSE OF PROPORTION.NEXT, MOVE THE SPEAKER 6 – 8 INCHES (15 – 20 CM) FORWARD AND REPEAT THE LISTENING PROCESS. REPEAT THIS PROCESS, MOVING THE LOUDSPEAKER FORWARD IN 6 – 8 INCH (15-20 CM) INCREMENTS. WHEN YOU REACH THE POINT FROM WHICH MOVING THE SPEAKER FORWARD SOUNDS WORSE THAN THE PREVIOUS LISTENING POINT, MOVE THE LOUDSPEAKER BACK TO THIS POSITION AND MARK THIS DISTANCE FROM THE REAR WALL.MIDRANGE—PLACEMENT IN RELATION TO SIDE WALLS FOR LATERAL PLACEMENT BEGIN BY DIVIDING THE ROOM WIDTH BY 14. INITIAL PLACEMENT OF THE LOUDSPEAKERS WILL BE AT 3 AND 11. THE DISTANCE FROM THE LOUDSPEAKER TO THE EARS HAS TO BE PRECISELY EQUAL. THIS MEASUREMENT IS CRITICAL. THE MUSIC FOR THIS PROCESS SHOULD BE A FEMALE VOICE AND PIANO. WE ARE LISTENING FOR THE IMAGE OF HER VOICE TO BE FOCUSED. THE RULE FOR THE TOE-IN IS TO PICK A POINT APPROXIMATELY 1 –2 FEET (. M) BEHIND THE LISTENER’S HEAD. TOE THELOUDSPEAKERS IN TO INTERSECT AT THAT POINT. IF THE SOUND IS TOO BRIGHT, TOE THE SPEAKERS OUT A LITTLE MORE. IF THE SOUND IS TOO DULL, TOE THE SPEAKERS IN A LITTLE MORE. REPEAT THE ABOVE PROCESS WITH THE LOUDSPEAKERS AT THE 4 AND 10 POSITION. THEN REPEAT, ONCE AGAIN WITH THE SPEAKERS AT THE 5 AND 9 POSITION. SUMMARYONCE THE INITIAL PROCESS HAS BEEN COMPLETED, RETURN TO THE BASS SET-UP TO ENSURE THAT THE LOUDSPEAKERS ARE THE PROPER DISTANCE FROM THE BACK WALL. WHEN THE PROCESS HAS BEEN COMPLETED, MARK THE SPEAKER LOCATION WITH TAPE SO THAT THE SPEAKERS CAN BE RETURNED THERE FOR FURTHER LISTENING. POSITIONING—MPROJECTS IN RELATION TO THE LISTENER• THE SPEAKERS AND THE LISTENER SHOULD FORM AN ISOSCELES TRIANGLE.• THE LISTENER SHOULD BE EXACTLY EQUIDISTANT BETWEEN THE TWO LOUDSPEAKERS. THE BEST WAY TO DETERMINE THIS IS WITH A PIECE OF STRING. PICK A FIXED SPOT AT THE LISTENING POSITION. RUN THE STRING FROM THIS SPOT TO THE FRONT OF THE TWEETER OF THE LEFT SPEAKER. REPEAT THE PROCESS FOR THE RIGHT SPEAKER. IT IS CRITICALLY IMPORTANT TO KEEP THIS DISTANCE PRECISELY THE SAME. CONNECTIONSCONNECTIONS SHOULD BE MADE WITH ALL ELECTRONIC EQUIPMENT (AMPLIFIERS, PREAMPLIFIERS) TURNED OFF. THERE ARE TWO TERMINALS AT THE BACK OF THE SPEAKER. THE TERMINALS ARE INSULATED TO ACCEPT A VARIETY OF CABLE TERMINATIONS FOR MOST APPLICATIONS AND TO PREVENT ANY LIKELIHOOD OF ELECTRICAL SHOCK, EVEN WHEN THE SPEAKERS ARE USED WITH THE HIGHEST POWERED AMPLIFIERS. DO NOT USE TOOLS TO TIGHTEN THE BINDING POSTS.BREAK-INA LOUDSPEAKER IS A MECHANICAL DEVICE AND AS SUCH REQUIRES AN EXTENDED INITIAL PERIOD OF NORMAL USE DURING WHICH A NOTICEABLE IMPROVEMENT IN SOUND QUALITY WILL OCCUR. DO NOT ATTEMPT TO ACCELERATE THE BREAK-IN PROCESS BY PLAYING SINE WAVES, TONE SWEEPS, BREAK-IN CDS OF ANY SORT, OR OTHER GENERATED SIGNALS.CARE:FOR ALUMINUM PANELS USE A LINT-FREE SOFT CLOTH (PROVIDED IN ACCESSORY KIT). FOR PAINTED SURFACES, USE A PRODUCT SUCH AS MEGUIAR’S PROFESSIONAL FINALINSPECTION 34. DO NOT USE CLEANERS THAT CONTAIN AMMONIA, STRONG SOLVENTS, OR ABRASIVE MATERIALS.

音响技术
AIWA CDC-X1765MYL汽车音响“复活”记(上)
重庆尹江
1、一台废弃的汽车音响
近日，在整理我的零件资源库时，一台AIWA CDC-X1765MYL汽车音响主机映入我的眼帘。
这应该是10年前入手的一台机子，当时是准备作为拆机零件包用的，因为看起来电路板比较完整，又是AIWA的牌子，所以就手下留情，让它“偷生”至今。
这台音响的CD机芯机械部分有故障，又没有控制面板，所以没法使用。
拆机检查了一下，主控芯片，音量控制，功放，收音头。
通过网上搜来的电路图和说明书，知道它的控制面板是以PD16432B为核心的带按钮输人和液晶显示驱动电路。
网络上搜遍了，也没有这个面板的介绍和出售。
甚至连这台机器的介绍资料都没有。
难怪，这台机器应该是AIWA为欧美汽车OEM制造的，国内市场肯定是没有的，生产年限也是很久远了。
要自己再造一块控制面板，难度确实有点大。
如果要这台机器起死回生，就必须另辟蹊径了。
2、改造设计思路
因为CD机芯存在故障，一时难以修复，且使用CD的机率实在不高，所以，暂时不管CD 功能。
因为主要看中的是AIWA音响的音质，所以，重点是功放、音量控制功能的恢复。
一旦成功，就可以改造成为一台四路输入、4×34W的四通道功放，用手机作为音源，足以满足非专业的耳朵需求。
顺便把FM功能恢复，听听FM音乐也不错。
这些外围芯片，都受CPU的控制，如何让CPU接收我的指令呢?必须要按CPU的通信协议，向它发送控制指令，并接收它发回的显示信息。
前面已经介绍，自己再造控制面板的难度有点大，而且要掌握它的通信控制协议确实不是一时半会儿就能够完成的。
因此，我的想法是，自已用一块51单片机作为新的主控芯片，取代原来的CPU，对收音头、音量控制、功放IC进行控制。
输入和显示可以用手里闲置的一块7”触摸屏，瞬间就“高、大、上”了许多。
改造后的系统设计如图1所示。
3、音量控制IC LC75374E
LC75374E是SNAYO公司生产的车载音响电子音量、音调控制集成电路。
外围原件很少。
能够提供音量、平衡、低音、高音、超重低音/高音调节以及4路立体声音源切换控制功能。
具有81级音量控制、16级平衡控制、15级低音和高音控制、11级超重低音/高音控制、16级输入增益控制和3级输出增益控制。
所有功能通过CCB串行总线进行控制。
CCB是三洋公司制定的一种串行原始总线格式，所有的芯片总线地址均由三洋公司分配和掌握。
CCB控制时序图见图2。
CCB控制协议要求应用程序必须按规定的时序和数据格式进行串行数据的传输。
CCB控制信息是单向传输控制，即由单片机控制LC75374E，无反馈信号。
总线由CE、CL和DI三条线组成。
CE是控制使能信号，单片机给CE置高电平时，可以输入数据，完成后置低电平；DI是数据线，按时序串行输出地址和数据；CL是移位时钟信号，每1位数据对应1个时钟脉冲信号。
LC75374E控制指令每帧有52位，8位地址(10000001二进制)和44位数据。
44位数据格式见表1。
音量、音调控制电路的改造，主要是断开LC75374E集成电路的脚CL、脚DI、脚CE 与原CPU的连接，改接至单片机IO口控制。
按照SANYO CCB总线控制协议，对单片机编程控制LC75374E。
需要注意的是，在LC75374E四路输出信号外置电路上，设计有三极管静音电路。
型号为DTC363TK的NPN数字三极管，其C、E极分别接在信号线和公共端上，其B极内置有限流电
阻，所以直接在B极施加高电平，输出信号即对地短路，达到了静音的目的。
改造时，可以把三极管b级控制信号接至单片机控制，也可以直接将B级控制信号悬空，使其外置静音功能失效。
单片机通过软件控制LC75374E内置静音功能即可(LC75374E控制数据D35数据位)。
4、功放芯片HA13158
HA13158是日立公司生产的一款4通道BTL功放集成电路。
专为汽车音响设计，具有高输出和低失真的特点。
每通道最大能够输出34W功率。
HA13158电路功耗低、内置软热限制器、外围元件少、低输出噪声、内置高可靠性保护电路(浪涌、T.S.D和ASO等)。
电路内置有独立的待机和静音控制。
HAl3158原理框图见图3，引脚功能见表2。
功率放大电路部分的改造，主要是断开②脚(STBY待机)、⑩脚(MUTE静音)与原CPU的连接，改接至单片机IO口控制。
②脚加35V或0.05mA电源时，功放IC正常工作；②脚开路或接地，IC进入待机状态。
⑩脚加35V或0.2mA电源时，功放IC正常工作；⑩脚开路或接地，IC 进入静音状态，功放输出关闭。
HA13158各引脚功能描述见表2。
