La partie de boîtier arrière (210) et le premier couvercle avant (220) définissent ensemble une chambre de réception et une pluralité de premiers conduits d'air en communication avec la chambre de réception. Le premier couvercle avant (220) et le second couvercle avant (230) définissent ensemble au moins un second conduit d'air en communication avec la chambre de réception. La chambre de réception est configurée pour recevoir un dispositif de sortie d'air (300). Une pluralité de premières sorties d'air (311) sont disposées sur une partie de paroi périphérique (310) du dispositif de sortie d'air (300), et au moins une seconde sortie d'air (321) est disposée sur une première partie d'extrémité axiale (320). Chacune des premières sorties d'air (311) est conçue pour être en communication avec au moins un premier conduit d'air, et chacun des premiers conduits d'air est en communication avec l'une des premières sorties d'air (311). Chacune des secondes sorties d'air (321) est conçue pour être en communication avec un ou plusieurs seconds conduits d'air, et chacun des seconds conduits d'air est en communication avec un ou plusieurs secondes sorties d'air (321).
