PURPOSE:To position fixedly an acoustic image in front by fitting a rectangular loudspeaker for reproducing a heavy low-pitched sound, to the center part of a dashboard of the front part in a car room, and driving it by a three dimension reproducing system. CONSTITUTION:Loudspeakers 7, 8 are installed at the left and right positions of a rear panel 2 of the rear part in a car room, and a woofer 9 for reproducing a heavy low-pitched sound is installed in the center part of a deashboard 3 of the front part. A three dimension reproducing system is a system for reproducing a sound by the left and right loudspeakers 7, 8 for reproducing an acoustic signal of a general band, and simultaneously, for emphasizing and reproducing further a low-pitched sound of a low-pitched sound area by one exclusive loudspeaker for reproducing a heavy low-pitched sound, therefore, by installing the loudspeaker 9 in the center part of the front in the car room, variations of sound pressure in each seat position are reduced to the minimum, and a good sound can be reproduced. |
