Digital sound file playback reproducer

Abstract

A digital sound file playback reproducer includes a housing in which at least a connection port, a sound source output unit, and a processing unit are provided. The connection port is adapted to connect with an external recording medium having sound filed stored thereon. The processing unit picks up and processes the sound files in the externally connected recording medium, and sends the processed sound files to the sound source output unit. Since the digital sound file playback reproducer does not include an internal memory, a consumer of existing recording media, such as memory cards and USB flash disks, could buy it without wasting money in repeated memory.
