Title:
MOBILE TERMINAL FOR REALIZING HIGH-FIDELITY MUSIC PLAYBACK
Document Type and Number:
WIPO Patent Application WO/2015/127832
Kind Code:
A1
Abstract:
The present invention relates to the technical field of mobile terminals, and particularly, to a mobile terminal for realizing high-fidelity music playback. The mobile terminal comprises a processor, a memory, and a power amplifier. The mobile terminal also comprises a digital-to-analog converter and a clock generation and distribution apparatus. The processor comprises an application processor or a digital signal processor. The processor reads a music source file in the memory and performs audio decoding of the music source file to obtain a digital audio signal. The digital-to-analog converter receives the digital audio signal, and performs digital-to-analog conversion to obtain an analog audio signal. The power amplifier is used for amplifying the analog audio signal and outputting the analog audio signal. The clock generation and distribution apparatus provides synchronous clocks to the processor and the digital-to-analog converter. The mobile terminal provides high-fidelity music playback quality and has low cost.
