1. An assembly for a turbomachine turbine extending along an axis (X) comprising:
an ejection cone (100) comprising a radially outer annular wall (102) delimiting a flow duct for a flow of hot gases and an acoustic box arranged radially inside said outer annular wall (102), the acoustic box comprising a radially inner annular wall (104), said acoustic box comprising a plurality of acoustic partitions extending radially outward from the inner annular wall of the acoustic box,
a connecting member (106) inserted axially between an exhaust housing and the ejection cone (100), the connecting member (106) comprising an upstream annular flange (108) attached to the exhaust housing and a plurality of downstream securing tabs (110) connected to the inner annular wall (104),
wherein the connecting member includes an annular sealing shroud (112) comprising an upstream portion surrounding the plurality of downstream securing tabs (110) of the connecting member (106) to cover spaces located circumferentially between the plurality of downstream securing tabs (110), the annular sealing shroud positioned axially between the upstream annular flange (108) of the connecting member (106) and the radially inner annular wall (104),
the connecting member further comprising:
a downstream annular seal (118) mounted at a downstream end of the sealing shroud (112) and located radially opposite the radially inner annular wall (104) of the ejection cone (100), or
a upstream annular seal (122) mounted at an upstream end of the sealing shroud (112) and located radially opposite the outer annular wall (102) of the ejection cone (100).
