1. A set for an ejection cone of an aircraft turbomachine, comprising:
a first annular wall centered on a longitudinal axis of axial direction oriented from upstream to downstream, and
a plurality of first partitions and second partitions extending substantially perpendicularly from the first annular wall,
wherein the first partitions extend generally in the axial direction and are distributed circumferentially around the first annular wall,
wherein the second partitions extend generally in a circumferential direction between pairs of adjacent first partitions and are distributed circumferentially around the first annular wall in at least one circumferential row,
wherein the first annular wall, the first partitions and the second partitions define therebetween a plurality of acoustic enclosures distributed around the first annular wall,
wherein the second partitions are bent walls comprising at least one portion arched in the axial direction upstream or downstream,
wherein an assembly formed by the first and second partitions is attached to the first annular wall with first attachment members arranged upstream and second attachment members arranged downstream, and
wherein the first attachment members are offset circumferentially relative to the second attachment members.
