Abstract

L'invention concerne une enceinte acoustique comprenant au moins une enceinte et un haut-parleur. Un tube d'évacuation de chaleur, constitué par un tube fermé qui contient un liquide sous vide partiel, comporte une extrémité placée de manière à absorber la chaleur développée par la bobine mobile et une autre extrémité portant un dissipateur thermique, en communication avec l'extérieur de l'enceinte. La chaleur développée par la bobine mobile est ainsi évacuée dans l'atmosphère, à l'extérieur de l'enceinte. L'invention s'applique notamment à des enceintes acoustiques anti-résonnantes.
