目前市场上有很多语音录放系统，如录放音玩具、录音笔等，大多采用了单片机控制一个语音芯片，再接一个FLASH存储器的结构。单片机可以控制录放时间，选取特定时间段的播放以及单多声道的录放，容易通过改变外接存储FLASH改变录放时间。 我们做的是一个简单模型，只能录放。 只需要录音和放音时的外部 ROSC 端振荡电阻不同就能改变声音的录入和播放速度，录入的时间越短音质越好，录入的时间越长音质越差 它采用模拟量直接存贮技术，因此保真度高，音质好 -Currently on the market there is a lot of voice recording systems, such as sound recording toys, sound recording pens and so on, most of the single-chip microcomputer to control the use of a voice chip, making the structure of a FLASH memory. Single-chip microcomputer can control the playback time, select a specific period of time many of the players, as well as single-channel recording, easy to FLASH memory by changing the external playback time change. We make a simple model, only playback. Required only when the recording and playback-side oscillation of the external resistor ROSC will be able to change different recording and playback of sound speed, the shorter the time of admission, the better sound quality, longer recording sound worse using direct ana

经过一段时间的使用，上次的硬盘MP3播放器增加了USB下载文件功能； 汉字LCD显示功能；子文件夹功能等。并对软件做了一些修改。并将 硬件电路图画出来了。由于做得仓促，难免有不妥之处，请大家谅解， 欢迎指出错误。谢谢。-After a period of use, the last of the hard disk MP3 player, an increase of USB download files function characters LCD display Subfolders functions. And the software to do some modifications. Hardware circuit and the pictures came out. As a result of doing a rush, inevitably something wrong with the U.S. understanding, please welcome to point out the error.谢谢.
