DIGITAL AUDIO SYSTEM OF VEHICLE

摘要

PURPOSE: A digital audio system of a vehicle is provided to play back digital audio data modulated for a set frequency band by using the existing car audio player, and to allow a driver to listen to high quality of music by playing back digital audio data without an economic burden and outputting the data through a speaker. CONSTITUTION: A digital audio system of a vehicle consists of a car audio player(10) converting a specific frequency band of music received via an antenna(30c) into stereo sounds and outputting the sounds via a speaker(40), and a portable digital audio player(20) reading digital audio data out of an optical disk, converting the digital audio data into analog audio signals and outputting the signals through an earphone. As the car audio player is set for a driver to select the set frequency band with a button of an operating panel, the car audio player processes the modulated signals of the set frequency band into audio signals and then outputs the audio signals via the speaker. Thereby, a driver and passengers listen to high quality of music output through the speaker in a vehicle.
