Abstract: The present disclosure provides example electronic devices, auxiliary materials, and rear housing assemblies of an electronic device. One example electronic device includes a rear housing, a middle frame, a functional component, a speaker box, and an auxiliary material, where the rear housing covers the middle frame and forms a mounting cavity together with the middle frame. The functional component, the speaker box, and the auxiliary material are disposed in the mounting cavity. The functional component is adjacent to the speaker box. A rear acoustic cavity of the speaker box is connected to the mounting cavity. The auxiliary material is bonded between the rear housing and the functional component. The auxiliary material has a weak-adhesion surface and a strong-adhesion surface that are opposite to each other. The weak-adhesion surface is bonded to the functional component, and the strong-adhesion surface is bonded to the rear housing.

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: This application relates to a loudspeaker and an electronic device. In one example, the loudspeaker includes a cone frame, a first sounding unit, a second sounding unit, and an elastic suspension. The first sounding unit includes a magnetic circuit structure mounted on the cone frame, an annular vibrating diaphragm, and a voice coil connected to the annular vibrating diaphragm. The second sounding unit is arranged coaxially with the first sounding unit, where the second sounding unit is mounted in the middle of a side that is of the magnetic circuit structure and that faces the annular vibrating diaphragm. The elastic suspension is configured to elastically support the voice coil and the annular vibrating diaphragm on the cone frame.
