Abstract
An acoustic spatial adjustment system may be provided that includes: a wireless communication module which receives a voice signal from a mobile terminal connected thereto by wireless communication; an adjustment controller which filters the voice signal in order to generate a sound source signal for focusing an output of the voice signal transmitted from the wireless communication module on a bright zone (BZ); an amplifier which divides the sound source signal transmitted from the adjustment controller into multi-channels and amplifies; and a plurality of speakers which output the sound source signal transmitted from the amplifier. As a result, the sound can be focused on a specific zone in the vehicle by using existing mounted speakers in the vehicle or by installing only additional speakers for performance improvement. Also, the individually distinguished sound (audio signal of a stereo system, CD, DVD, etc., a telephone voice signal connected by Bluetooth, etc.) can be adjusted to be heard only in a specific zone (bright zone) and can be adjusted to be heard very small or not to be heard in a zone (dark zone) other than the specific zone. Also, the user is able to select or adjust the sound focusing in the vehicle.
