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.
