说明：  采用TA7270集成做功放，而且无NE5532前置电路做运放，所以音量较小，适合做电脑功放用。 程序部分没有对平衡量进行存储控制，故开机平衡量为32DB，显示屏SM16312板按键没有做相应消抖动 处理，并且2051的空间问题，没有加入摇控功能。 显示屏是VCD上拆下来的，所以想做这类实验的朋友所拆下来的屏不一定与我这个一样！如果直接套用 我的源程序显示会不正常，或按键不起作用！想解决这个问题就只有查看相关SM16312的控制协议资料， 然后在程序里做相应修改即可！ SM16312显示板没有电路图，板上一般有接口英文标注，具体怎么接看程序的引脚定义。 本人做这个实验的目的也是想搞懂SM16312以及PT2314的通讯协议及工作原理！喜欢这类实验制作的朋友不凡一试！
(TA7270 integrated amplifier, and NE5532 prefix circuit op amp, so the volume is small, suitable computer amplifier with. Part of the program is not to balance the amount of storage control, so power balance amount 32DB, the display of SM16312 board buttons accordingly eliminate jitter processing, and 2051 space problem, not a member of the remote control function. The screen the VCD removed, so want to do the friends such experiments removed screen is not necessarily the same with me this! Directly apply my source display is not normal, or the key does not work! Want to solve this problem and the only to view related SM16312 control protocol data, and then the program can be modified accordingly! The SM16312 display board schematics, board general interface English marked specifically how then to see the pin definition of the program. I do this experiment also aims would like to get to know the SM16312 as well as the PT2314 of the communication protocol and works! Extraordinary friend )
