Abstract
A vehicle audio video navigation (AVN) system may be provided that includes: a plurality of source providers which receives a sound source; a user operation unit which selects at least one of a plurality of the sound sources input from the plurality of the source providers and selects a focusing zone of the sound source; a processor which generates a sound source signal for focusing an output of the selected sound source on the focusing zone; and a multi-channel amplifier which outputs the sound source signal. As a result, the focusing zone of each sound output within a vehicle can be individually controlled. Particularly, the focusing zone of each sound can be easily selected and controlled without changing the location of the speaker within the vehicle. Also, the sound source and the focusing zone within the vehicle can be selected and controlled only by adding an external processor without replacing the AVN device provided in the vehicle.
