Abstract

Enceinte acoustique (1) comprenant : - une paroi externe (20) non conductrice de la chaleur et définissant au moins en partie un caisson (25), - au moins un haut-parleur (5) électrodynamique comportant un moteur (48), le haut-parleur ayant une portion périphérique (50) fixée sur la paroi externe, et - au moins un circuit électronique (10) de commande du haut-parleur. Le moteur et le circuit électronique sont liés à un même organe (15) de l'enceinte acoustique. L'organe est conducteur de la chaleur et comporte une surface (66) d'échange propre à être traversée par un flux de chaleur (68) circulant dans l'organe en provenance du moteur et du circuit électronique lorsque l'enceinte acoustique est en fonctionnement, le flux de chaleur étant destiné à se dissiper dans l'air extérieur (76) à l'enceinte acoustique ou à passer dans un élément conducteur de la chaleur extérieur à l'enceinte acoustique.
