Title (EN) AQUATIC ACOUSTIC ENCLOSURE
(FR) ENCEINTE ACOUSTIQUE AQUATIQUE
Abstract:
(EN) The present invention concerns a sound-emitting device (1) immersible or semi-immersible in a liquid, comprising a rigid hollow body (3) having at least one opening at one of its ends (31, 32) and designed to be at least partially submerged in the liquid, in such a way that the main axis (4) passing through the opening of the hollow body (3) is substantially vertical, and at least one electrodynamic loudspeaker (5, 51, 52) comprising at least one diaphragm (6, 61, 62), at least one magnet and at least one moving coil (7, 71, 72). The at least one loudspeaker (5, 51, 52) is fixed to the inside of the hollow body (3) in the vicinity of at least one submerged opening of the hollow body (3), the device (1) and its hollow body (3) being designed such that, when the device (1) is at least semi-submerged, the diaphragm (6, 61, 62) of the at least one loudspeaker (5, 51, 52) is in contact with the liquid on at least one of its sides and closes the submerged opening (32) of the hollow body (3).
(FR) La présente invention concerne un dispositif (1) d'émission de son immersible ou semi-immersible dans un liquide, comprenant un corps creux rigide (3) ayant au moins une ouverture à l'une de ses extrémités (31, 32) et agencé pour être au moins partiellement immergé dans le liquide, de façon à ce que l'axe principale (4) traversant l'ouverture du corps creux (3) soit sensiblement vertical, et au moins un haut-parleur électrodynamique (5, 51, 52) comprenant au moins une membrane (6, 61, 62), au moins un aimant et au moins une bobine mobile (7, 71, 72). L'au moins un haut-parleur (5, 51, 52) est fixé à l'intérieur du corps creux (3) à proximité d'au moins une ouverture immergée du corps creux (3), le dispositif (1) et son corps creux (3) étant agencés pour que, lorsque le dispositif (1) est au moins semi-immergé, la membrane (6, 61, 62) de l'au moins un haut-parleur (5, 51, 52) est en contact avec le liquide à au moins une de ses côtés et ferme l'ouverture immergée (32) du corps creux (3).
