Abstract

La présente invention concerne un dispositif monobloc et stéréophonique d'enceinte acoustique amplifiée. L'enceinte acoustique amplifiée selon l'invention comprend notamment : * deux haut-parleurs centraux destinés à reproduire les fréquences graves, l'un situé en façade et l'autre placé à proximité et à l'arrière de celui-ci, reliés pneumatiquement entre eux dans un compartiment étanche, * au moins un évent ne communiquant pas pneumatiquement avec ce compartiment étanche et reliant la partie intérieure de l'enceinte à l'extérieur de celle-ci, Chacun de ces deux haut-parleurs (1) et (2) destiné à reproduire les fréquences graves est alimenté par des canaux d'amplification distincts (3) et (3') et possédant chacun leur bande de fréquence spécifique.The present invention relates to a monoblock and stereophonic device for an amplified acoustic enclosure. The amplified acoustic enclosure according to the invention notably comprises: * two central speakers intended to reproduce the bass frequencies, one located on the front and the other placed near and behind it, pneumatically connected between them in a sealed compartment, * at least one vent not communicating pneumatically with this sealed compartment and connecting the inner part of the enclosure to the outside thereof, each of these two speakers (1) and ( 2) intended to reproduce bass frequencies is supplied by separate amplification channels (3) and (3 ') and each having their specific frequency band.
