a conductive member for forming an antenna radiator integrally with the annular member and the middle frame,
wherein the conductive member comprises a conductive foam, and the conductive foam is filled in a gap between the middle frame and the annular member,
wherein the conductive foam comprises a first portion located between the annular member and the middle frame and a second portion connected with the first portion;
and the second portion is connected between the annular member and the screen assembly,
wherein a first convex rib connecting the first portion is formed on the middle frame;
a first distance from a first surface connecting the first portion in the first convex rib to the annular member is smaller than a distance from a second surface connecting the second portion in the stepped structure to the annular member; and
a second distance from the first surface to the second surface is between 0.03 mm and 0.07 mm.
2 . The housing assembly according to claim 1 , wherein the conductive foam is divided into multiple sections, and each section of the conductive foam serves as a feed point to stimulate the antenna radiator to receive and transmit wireless signals in different frequency bands.
