Abstract: This application provides a speaker and a mobile terminal. The speaker includes a housing and a kernel located in the housing, where there is a front cavity and a rear cavity in the housing, the front cavity is in communication with the outside, and the rear cavity is an isolated cavity. In addition, to reduce a space area occupied by the entire speaker, the front cavity and the rear cavity are disposed in a stacked manner when being disposed. Specifically, the front cavity and the rear cavity are at least partially stacked along a thickness direction of the kernel. Therefore, the rear cavity is disposed in space of the entire speaker in the thickness direction of the kernel, to reduce an area occupied by the entire speaker in the mobile terminal on the premise that a size of the rear cavity meets a requirement.

Abstract: This application discloses a housing assembly, including a housing, a decorating part, and an adhesive assembly. The housing is provided with a through hole. The decorating part includes a substrate and a decorating ring protruding from the substrate. An air hole is disposed on the substrate. The air hole is located on an outer side of the decorating ring. The decorating ring is at least partially accommodated in the through hole. A gap is formed between an outer peripheral side surface of the decorating ring and a hole wall of the through hole. The adhesive assembly is attached between the substrate and the housing in a sealed manner. The adhesive assembly is disposed around the decorating ring and the air hole, and a channel is formed between the adhesive assembly and the outer peripheral side surface of the decorating ring.
