本次课题设计是一个音乐彩灯控制器.整个电路主要是由音乐节奏控制、音量大小、音调高低三个部分构成.
输入音频信号后,通过三极管对其放大后输出的信号来达到控制彩灯的循环点亮以及亮度大小和彩灯多少的控制.我们使用了NE555时基电路构成的单稳态电路来控制音量大小部分；用NE555时基电路组成的多谐振荡电路来实现循环节奏部分的点亮；用高低通滤波电路来实现音调部分的.
随着音乐节奏的快慢循环部分的彩灯也随着节奏变化,当输入音调发生变化时会通过两个不同颜色的灯来展现,输入音量变大时这一部分的彩灯亮度也随之增加.整个音乐彩灯控制器方案就是这样.
关键词：555 时基电路；音乐大小；节奏；音调

Answer 1

The project designed is a controller for music color lamp.The whole circuit is composed of three parts:music rhythm regulator,volume and tone .
After the audio signal input,the light illumination relay,LED brightness and its numbers are controlled by output signals amplified through the triode.We use the monostable circuit to control the volume made by the NE555 time-base circuit which formed the multiple harmonic oscillation circuit to achieve the light illumination of the circulation rhythm section and realized the tone component with high and low pass filter circuit.
The color lamps change with the rhythm of the tempo,Two different coloured lights show the input tone changes and the lamp brightness increases with the louder input volume,which is the entire music color lamp controller scheme.
Key words:555 time-base circuit; music volume; rhythm; tone
