Title
(EN) DEVICE FOR SOUND REPRODUCTION
(FR) DISPOSITIF DE REPRODUCTION SONORE
Abstract
(EN)
Device (1, T) for reproducing sounds, in particular sounds intended to be perceived by a subject using said device, comprising a containment element (2) in which a transducer (4), preferably of an electro-acoustic type, is housed, which is configured to emit vibrations substantially corresponding to the sound to be reproduced, and a liquid or gel state medium (10) which is contained inside said containment element (2), said medium (10) being configured to transmit the sound vibrations generated by said transducer (4) to a transmission element (12, 12') intended to be applied in direct contact with a body area of said user, thereby transmitting said sound vibrations to said body area, wherein the containment element (2) consists of a single housing chamber and the transducer (4) is immersed entirely or partially in the medium (10) inside said chamber.
(FR)
La présente invention concerne un dispositif (1, T) pour reproduire des sons, en particulier des sons destinés à être perçus par un sujet à l'aide dudit dispositif, comprenant un élément de confinement (2) dans lequel un transducteur (4), de préférence d'un type électro-acoustique, qui est configuré pour émettre des vibrations correspondant sensiblement au son à reproduire, et un milieu d'état liquide ou gel (10) qui est contenu à l'intérieur dudit élément de confinement (2), ledit milieu (10) étant configuré pour transmettre les vibrations sonores générées par ledit transducteur (4) à un élément de transmission (12, 12') destinée à être appliquée en contact direct avec une zone corporelle dudit utilisateur, transmettant ainsi lesdites vibrations sonores à ladite zone corporelle, l'élément de confinement (2) consiste en une seule chambre de logement et le transducteur (4) est immergé entièrement ou partiellement dans le milieu (10) à l'intérieur de ladite chambre.
