【摘要】 本文介绍了采用51系列AT89C51单片机为核心部件,以及其它外围电路及其相应接口,设计一个将上位机发送过来的多路音频及控制数据按照预定的目标分别输出到若干扬声器中去,从而控制每个扬声器的音量的大小和播放音源的系统。该系统的设计与实现对于医学上的人体器官发声模拟有一定的作用和意义。更多还原

【Abstract】 The design of multi-track playing control system and realization of software and hardware are in detail introduced by using AT89C51 single-chip,belonged to a series of MCS-51,as the important component,together with other peripheral circuits and their interface circuits in this paper.This system receives multisound and its controlled data from computer and outputs them to some loudhailers so as to control the sound volume and source of everyone.The design and realization of this system make sense of simulating human apparatus of making sound.更多还原
