摘　　要：针对目前市面上音乐节奏彩灯成本高、需要提前编程、效果单一等缺点,设计了一种基于频谱分析的音乐节奏灯光系统。该系统以单片机为控制核心,配合MSGEQ7芯片、WS2812彩灯模块、固态继电器模块,蓝牙音频模块等,可以实现对用户播放的音乐进行频谱分析,根据频谱特征判断音乐的鼓点节奏和音乐氛围,并控制彩灯随着音乐节奏进行不同效果的变化。该系统具有操作简单、无需编程、即插即用、效果丰富、识别精准等特点。In view of the shortcomings of music rhythm lights in the market,such as high cost,need to be programmed in advance,and single effect,a music rhythm lighting system based on spectrum analysis is designed.The system takes single-chip microcomputer as the control core,and cooperates with MSGEQ7 chip,WS2812 color lamp module,solid-state relay module,Bluetooth audio module and so on.It can analyze the frequency spectrum of the music played by users,judge the drumbeat rhythm and music atmosphere of music according to the spectrum characteristics,and control the color lights to change with the music rhythm in different effects.The system has the characteristics of simple operation,no programming,plug and play,rich effect,accurate recognition and so on.
