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 provides a sound output apparatus including a housing, a first speaker, and a second speaker. A sound outlet and a first air vent that are spaced are disposed on the housing. A first channel and a second channel that are separated are disposed on the housing. A rear cavity of the first speaker communicates with the outside of an earphone through the first channel and the first air vent of the housing. The second speaker is located on a side that is of the first speaker and that is away from the sound outlet. A front cavity of the second speaker communicates with the outside of the earphone through the second channel and the sound outlet of the housing, so that low-frequency performance of the first speaker is improved.

Abstract: Embodiments of this application provide a display terminal, and relate to the field of display technologies, to solve the problem that the overall screen-to-body ratio decreases due to a receiver disposed on a display terminal. The display terminal includes a middle frame, a display module, a vibrator, and at least one vibrating plate. The display module is connected to the middle frame, and an accommodation space is formed between the display module and the middle frame. At least a part of the vibrator is disposed in the accommodation space. The vibrator is connected to the display module or the middle frame. The vibrating plate is located in the accommodation space. An upper surface of the vibrating plate is connected to a lower surface of the display module. A lower surface of the vibrating plate faces the middle frame.
