Abstract

A digital audio assembly includes a digital signal processor (DSP) mounted and a digital analog converter (DAC) mounted therein. A universal serial bus (USB) socket is mounted in a front panel of a base member and electrically connected to the DSP. The USB socket can be connected to extra media. A secure digital memory card (SD card) socket is mounted in the front panel and electrically connected to the DSP. The SD card socket can receive a SD card and read the digital signals in the SD card. A sound-source input port is mounted in the front panel and electrically connected to the DAC, and a sound-effect input/output port is mounted in a rear panel of the base member and electrically connected to the DAC.

Claims

1. A digital audio assembly comprising:

a digital signal processor (DSP) mounted in the digital audio assembly;

a digital analog converter (DAC) mounted in the digital audio assembly;

a base member including a front panel and a rear panel opposite to the front panel;

a universal serial bus (USB) socket mounted in the front panel and electrically connected to the DSP, the USB socket can be adapted to be connected to extra media and the digital audio assembly reading the digital signals in the extra media via the USB connection;

a secure digital memory card (SD card) socket mounted in the front panel and electrically connected to the DSP, the SD card socket adapted to receive a SD card such that the digital audio assembly of the present invention can read and play the digital signals that are saved in the SD card;

a liquid crystal display mounted in the front panel and electrically connected to the DSP;

multiple functional switches respectively mounted in the front panel and electrically connected to the DSP for user to control the digital audio assembly;

a sound-source input port mounted in the front panel and electrically connected to the DAC; and

a sound-effect input/output port mounted in the rear panel and electrically connected to the DAC.

2. The digital audio assembly as claimed in claim 1 further comprising an interface port electrically connected to the DSP and adapted to be electrically connected to a PC such that the user can control the digital audio assembly via the PC, thereby the digital audio, assembly reads the digital signals from the extra media via the USB connection and transmits the digital signals from the extra media to the PC via the interface port such that PC can save the digital signals therein.
