"基于STC89C51单片机控制的音乐播放器设计与原理研究"

The thesis titled "Design of Music Player based on Single Chip Microcontroller with Program and Schematic" presents a creative and efficient music player designed using the STC89C51 single chip microcontroller. The music player is equipped with features such as song playback, song title display, and accompanying colorful lights. It utilizes infrared remote control for controlling song playback, enhancing not only functionality but also aesthetics. The design is divided into five main modules, including the single chip microcontroller core module, infrared remote control module, colorful light accompaniment module, sound module, and liquid crystal display (LCD) module for song information display. Each module is briefly introduced in the thesis, with a detailed explanation of the sound generation principle. The implementation of the design involves programming and debugging the system software using Keil software and designing and simulating the hardware circuit using Altium Designer. This comprehensive approach ensures smooth and successful design execution. Overall, the thesis highlights the significance of 51 single chip control systems, infrared wireless remote control technology, sound generation principles, and the utilization of Altium Designer for hardware circuit design and simulation. The music player design showcases innovation, functionality, and convenience, making it a valuable contribution to the field of electronic information science and technology.
