A diving mask supplemented with a device for facilitating the equalization of pressure across the eardrum of a user, comprising a mask body (20) configured to closely fit the face of the user so as to cover at least the eyes, and nose of the user. When in use, the mask body, and the face of the user define a first closed space, the mask body including a transparent window (22) through which the user sees; first, and second ear cups (26) for closely covering the ears of the user. The ear cups, the sides of the head of the user define a second, and third closed space around the ears of the user, respectively. Each of the earcups (26) includes a flexible ear cover (23) for covering an ear of the user; an external solid frame (30) for supporting the ear cover; and a solid outer cover for protecting the ear cover; first, and second tubes extending from the mask body. Each of the first and second tubes having a first end, and a second end. The first ends communicate with the first closed space defined by the mask body, and the face of the user. The second ends communicate with the second, and third closed spaces, respectively, defined by the ear cups, and the sides of the head of the user; and a strap arrangement connecting between each of the first, and second ear cups, the mask body, and between the first, and second ear cups.
Ce masque de plongée, équipé d'un dispositif d'équilibrage de la pression de part et d'autre de la membrane tympanique, comporte un corps de masque (22), conçu de manière à épouser étroitement les formes de la face du plongeur et à couvrir au moins ses yeux et son nez. Lorsque ce masque est porté, il délimite avec la face du plongeur, un premier espace clos. Ce corps de masque est pourvu d'un hublot transparent (22) permettant au plongeur de voir. Le masque comporte également deux coquilles (26) couvrant les oreilles du plongeur. Ces coquilles délimitent, avec les cotés de la tête du plongeur, un deuxième et un troisième espace clos autour des oreilles du plongeur. Chacune de ces coquilles (26) est pourvue d'une protection souple de l'oreille (23), d'un cadre extérieur rigide (30) maintenant en place la protection, et d'une carapace extérieure rigide protégeant la protection de l'oreille. Ce masque comporte également deux tubes partant du corps de masque. Ces deux tubes ont, chacun, deux extrémités. Les premières extrémités sont en communication avec le premier espace clos et les secondes extrémités avec le deuxième et le troisième espace, respectivement. Un système de sanglage relie les deux coquilles entre elles et au corps de masque.
