摘要： This application provides a decorating assembly, a housing assembly, and an electronic device. The decorating assembly includes a decorating part, a first adhesive layer, a cover, and a waterproof breathable film. The decorating part includes a base and a decorating ring. The base includes a first surface and a second surface that are oppositely disposed. The decorating ring protrudes from a peripheral edge of the first surface. A breathable space is disposed in the base. The breathable space penetrates from the first surface to the second surface. The breathable space is located inside the decorating ring. The first adhesive layer is located inside the decorating ring and is connected to the first surface through fastening. The first adhesive layer forms a first channel connected to the breathable space. The cover is connected, through fastening, to a surface that is of the first adhesive layer and that faces away from the base. A first gap is formed between a peripheral side face of the cover and an inner side face of the decorating ring. The first gap is connected to the breathable space through the first channel. The waterproof breathable film is fastened onto the base and covers the breathable space. When the housing assembly having the decorating assembly is applied to the electronic device, the electronic device can quickly balance internal and external air pressure.

摘要： 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.

摘要： 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. The channel communicates with the gap and the air hole. The housing assembly can rapidly balance internal and external air pressure. This application further discloses a terminal.

摘要： This application provides a speaker module, including: a first enclosure, a speaker core, and a waterproof breathable film. The first enclosure is provided with an accommodating groove, the speaker core is mounted on the accommodating groove, the speaker core includes a sound diaphragm, a front sound cavity is formed between the sound diaphragm and the first enclosure, and a rear sound cavity is on a side that is of the sound diaphragm and that is away from the front sound cavity. The first enclosure is further provided with a resonant groove, a bottom of the resonant groove is provided with a communicating hole, and the resonant groove communicates with the front sound cavity through the communicating hole. The waterproof breathable film covers an opening that is of the resonant groove and that faces the rear sound cavity, to isolate the resonant groove from the rear sound cavity, so as to balance atmospheric pressure of the front sound cavity and the rear sound cavity when the speaker module does not work, avoid a problem that sound diaphragm is shifted and sound quality of the speaker module is affected due to different atmospheric pressure of the front sound cavity and the rear sound cavity, and improve the sound quality of the speaker module. This application further provides an electronic device.

摘要： Embodiments of this application provide a speaker and a terminal. The speaker includes an enclosure with accommodating space and a sound production monomer fastened in the accommodating space. The sound production monomer has a diaphragm that vibrates to produce a sound, the enclosure includes a first inner bottom wall and an inner sidewall fastened to the first inner bottom wall, the diaphragm is fastened to the inner sidewall to isolate the accommodating space into a front cavity and a rear cavity, the first inner bottom wall is located in the front cavity, a sound outlet hole penetrates through the inner sidewall, the front cavity is in communication with the sound outlet hole to form a front cavity channel, the diaphragm is tilted relative to the first inner bottom wall, and a diameter of an end of the front cavity that is in communication with the sound outlet hole is greater than a diameter of an end of the front cavity that is away from the sound outlet hole. Therefore, an airflow becomes gentle, intensity of a circumferential vortex of a ring is reduced, noise is reduced, and a sound effect of the speaker is improved.
