Abstract

L'invention concerne un émetteur de son comprenant au moins une membrane vibrante montée sur la paroi d'une enceinte de sorte qu'une face de la membrane du haut-parleur rayonne dans l'enceinte, l'enceinte étant pourvue d'un évent formant conduit entre un débouché dans l'intérieur de l'enceinte et un débouché à l'extérieur de l'enceinte, caractérisé en ce que l'évent comporte des moyens d'atténuation de turbulence aérodynamique au niveau d'au moins un des débouchés, cette turbulence étant consécutive à un écoulement d'air dans l'évent provoqué par des déplacements de la membrane de grande amplitude. L'invention concerne également un émetteur de son dans lequel l'a ir se déplace dans un conduit (33) s'étendant de la membrane à une sortie (35) du conduit (33) sur l'extérieur. L'invention a également pour objet un haut- parleur dont les organes ont une forme aérodynamique.
