The present invention relates to the designing of digital music players. The host computer of general digital music player comprises a microprocessor, an input module using keyboard, an LCD module, a decoding module, a D/A converter module, and a power amplifier module. Wherein the input module using keyboard, the LCD module, the computer peripheral bus interface module and the decoding module are all directly connected to the microprocessor, the D/A converter module is connected to the decoding module, the power amplifier module is connected to the D/A converter module. It is characterised in that: the host further comprises a computer's peripheral bus interface module which is connected to the microprocessor via the Data Bus, and a movable momory which is connected to the host computer via a computer's peripheral bus interface module. Its advantage is small volume, big capacity, simple operation, the high performance of antivibration, a low cost.
