【摘要】 音乐电疗通过音乐和音乐电信号作用于听觉和机体,提高或改善人的心理、生理状况,从而达到保健、防病和康复的目的。音乐电疗仪具有音乐治疗和理疗的双重功能,而且由音乐产生的电流易为人体所适应,故对疾病有着明显的治疗效果。若与各种传统的治疗手段结合使用,常能取得相得益彰的理想效果。传统的音乐电疗仪是以磁带机为音源,这样的音乐电疗仪存在很多缺点,磁带机长期使用具有易污损、易卡带、失真大、动态范围小,信噪比低,特别是机械噪声会时常窜入声道等通病;其体积庞大,必须在医院接受治疗,不适合家庭使用;操作烦琐,必须有专人来帮助才可完成治疗。随着数字技术的发展,本课题设计了一种以数字音乐为音源的音乐电疗仪,它不但很好地克服了传统音乐电疗仪的缺点,而且增加了存储文件和液晶显示的功能,这样可以很方便地选择不同音乐,可以使治疗信号透明化,使患者放心地接受治疗,进一步增加疗效。本课题完成的主要工作如下:1、完成了数字音乐电疗仪系统框架的设计,在功能上,实现了音乐播放、文件存储、电击治疗和数据的PC机采集与显示。2、完成了基于MP3解码器的音乐播放、基于FLASH存储器的文件存储、音乐电信号放大、数据采集和波形显示等硬件电路设计。3、完成了基于USB接口文件存储的下位机程序设计、基于MP3解码器的解码程序设计和基于液晶显示模块的波形显示程序设计。4、成功制作出一台数字音乐电疗仪样机,经调试,功能满足了设计要求,可实现音乐播放、治疗、液晶显示、音频文件存储和按键选择等功能。5、对样机进行了一些测试性实验。结果表明样机功能基本满足设计要求,治疗信号与音乐信号节奏基本一致,因此本课题理论分析正确,电路设计合理。更多还原

【Abstract】 Musical doctors work on human body by musical electronic signals and can improve men’s psychological and physical conditions, thereby have the function of keeping health, preventing illness and recovering. Musical doctors have the function of both musical treatment and physical therapy. Because human body is adaptive to the low-frequency electric current generated by music, their treatment is quite effective. With combination of traditional medical treatment means, the curative effect can be more effective.Traditional music doctors use magnetic tapes as source and turn out to have lots of weakness. Magnetic tapes are easily defiled and stuck after long-time usage, and their activity range is narrow with low signal-to-noise rate, which will introduce noise to normal sound track. In addition, traditional music doctor with magnetic tapes is bulky and heavy, therefore not suitable for domestic use. As its operation is complex, treatment can only be done with the help of professionals.A music doctor with digital music source is designed in this paper. It not only overcomes the disadvantage of traditional musical doctors, but also adds storage and LCD screen parts, which makes it more convenient to choose various music. The treatment procedure is transparent to patients and hence makes them feeling reassured, which further improve the curing effect.Main works are introduced in details:1. The system frame of music doctor has been designed, and some functions of the equipment have been achieved , including : play of music, saving files, therapy by electric, data collecting in PCand wave showing.2. Some kinds of hardware have been designed, including: the music-playing system, lying on the MP3 decoder; the files saving system, lying on the flash; the amplification of the electric signal system; the data collecting system and showing of the wave systems.3. Some programs have been finished, including: the saving of the files through the USB interface; the decoding design of the MP3 decoder; the showing of the waves in the LCD screen.4. Develope the prototype of the digital music doctor,and implement the fundamental function,such as playing music ,curing ,diaplaying with liquid更多还原
