Abstract: A terminal speaker includes an enclosure with accommodating space with an affixed sound production monomer. The sound production monomer has a diaphragm configured to vibrate to produce 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, dividing the accommodating space into front and rear cavities. The first inner bottom wall is in the front cavity. A sound outlet hole penetrates the inner sidewall. The front cavity is in communication with the sound outlet hole by a front cavity channel. The diaphragm is tilted relative to the first inner bottom wall. The perimeter of the end of the front cavity in communication with the sound outlet hole is greater than the perimeter of the end of the front cavity remote from the sound outlet hole.

Abstract: This application provides a decorating assembly, a housing assembly, and an electronic device. Gas flows between the outside of the electronic device, the first gap, the first channel, the breathable space, the waterproof breathable film, and the first space to implement a quick balance between internal air pressure of the first space and external air pressure of the electronic device. In addition, the waterproof breathable film is installed on the base, and the waterproof breathable film covers the breathable space, to ensure that when the decorating assembly is applied to the electronic device, the waterproof breathable film can prevent external liquid of the electronic device from entering the first space through the breathable space, thereby ensuring that the electronic device has relatively good waterproof performance.

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.

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.
