Abstract

Cet ensemble stéréophonique, destiné à un véhicule automobile, comprend plusieurs haut-parleurs FL', RL', FR' et RR' destinés à reproduire les fréquences audibles élevées et moyennes des canaux de gauche et de droite respectivement, et un haut-parleur unique 5 servant à reproduire les fréquences audibles basses des canaux de gauche et de droite. Les haut-parleurs destinés aux fréquences élevées et moyennes sont de petite taille, si bien que les espaces qu'ils occupent sont relativement faibles et ainsi l'espace limité de l'habitacle d'un véhicule automobile peut être effectivement utilisé tandis que l'effet stéréophonique n'est pas du tout perdu par l'ensemble de haut-parleurs, du fait que la directivité des fréquences audibles basses n'est pas aussi élevée que celle des fréquences audibles élevées et moyennes.This stereophonic assembly, intended for a motor vehicle, comprises several loudspeakers FL ', RL', FR 'and RR' intended to reproduce the high and medium audible frequencies of the left and right channels respectively, and a single loudspeaker 5 used to reproduce the low audible frequencies of the left and right channels. Loudspeakers intended for high and medium frequencies are of small size, so that the spaces they occupy are relatively small and thus the limited space of the passenger compartment of a motor vehicle can be effectively used while the Stereophonic effect is not lost at all by the speaker set, due to the fact that the directivity of low audible frequencies is not as high as that of high and medium audible frequencies.
