摘 要

现代社会，计算机信息技术高速地发展，人民的生活发生了日新月异的变化，由于智能化的加入生活愈发快捷。生活中，满足简单需求的不再是大家的诉求。人们向往更加方便和快速的生活，传统的电子产品将面临越来越多的考验，这对于音乐播放器与智能化的结合产生了巨大的契机。体感技术作为新兴事物越来越受到人民的关注，利用肢体动作与设备互动。它可以使人们做到与环境的交互也可以让人们获得轻松的体验。

普通的音乐播放器是通过按键控制，利用上下曲来控制歌曲，使用音量键控制声音。声音的输出则通过喇叭和耳机进行。体感式智能音乐播放器不仅实现了传统音乐播放器的基本功能，还加入了光学感测的体感技术。它可以使用肢体动作控制选择歌曲以及控制音量。体感式智能音乐播放器比传统音乐播放器的应用场景更加多样化。

体感智能音乐播放器以单片机为控制核心，实现对SD音频文件数据的存储读取和传输任务。解码芯片获得音频文件数据，把数字信号转化成模拟信号，最后经过扬声器播放声音。利用传感器接收不同的手势信号以控制并实现音乐播放器的开和关、选择曲目及音量调节等功能；为了让操作更加便捷易懂，同时还添加了屏幕实现可视化操作。

Somatosensory Smart Music Player

Abstract

In modern society, electronic information technology has always been rapid development, People"s lives have been improved in the intelligent. In life, the product is no longer simply to meet the demand. People"s lifestyles will become more convenient and fast in the future, the traditional electronic products will face more and more challenge. Smart music player has a huge opportunity. Somatosensory technology is a new thing with more and more people"s attention, the use of physical movements and equipment interaction. It makes people interact with the environment and let people get a relaxed experience.

Traditional music player is controlled by the button, the use of up and down to control the song, use the volume keys to control the sound. The output of the sound is through the speaker and headphones. somatosensory smart music player not only have the basic functions of traditional music player, but also add the sensory technology of optical sensing. you can use the body action control to select songs and volume. Somatosensory smart music player more than the use of traditional music players in life.

Somatosensory smart music player use single-chip as the control center, which implements the SD audio file data storage read and transfer tasks.Decoding chip get the audio file data, the digital signal to the analog signal,the speaker to play the sound. The music player uses the sensor to distinguish the gesture signal to achieve control of itself,Such as changing the song and volume functions. The addition of the screen makes the operation easier and observes your operation.
