MPMan是继Walkman、discman、MD后出现的一种新的便携式数码音频设备。它不是播放盒式录音带或CD,而是播放MP3格式声音文件。MPMan采用大容量的间存(FlashMemory)代替磁带或光盘来存储数码音乐,用MPEG Lay-er-3解压缩芯片播放具有激光唱盘(CD)音质的MP3音乐。它具有体积小(15mm厚,面积与一张3英寸磁盘相仿)、重量轻(连同电池只有140克)、不怕振动等特点。它由可充电电池供电,充电电池充电2小时,可连续使用9小时。MPMan完全没有机械传动部件,因而故障率极低,具有超长的使用寿命。它采用内置的闪存卡作为存储媒介,因此有电脑时代的Walkman之称。
MPMan is a new portable digital audio device that appears after Walkman, discman, MD. Instead of playing cassette tapes or CDs, it plays MP3 format sound files. MPMan uses large amounts of flash memory instead of magnetic tape or discs to store digital music and MPEG Lay-er-3 decompression chips to play MP3 music with compact disc (CD) quality. It has a small size (15mm thick, an area similar to a 3-inch disk), light weight (with the battery only 140 grams), are not afraid of vibration and so on. It is powered by a rechargeable battery that charges for 2 hours on a rechargeable battery for 9 hours of continuous use. The MPMan has no mechanical transmission at all and thus has a very low failure rate and an extremely long service life. It uses built-in flash memory card as a storage medium, so there is the computer age Walkman said.
