Abstract: An earphone is provided, and includes a housing, a loudspeaker, and a noise cancellation microphone, the housing comprises an internal space, and a sound pickup channel. The noise cancellation microphone is connected to the communication surface by the sound pickup channel. The housing comprises an outer housing and a frame, the housing is provided with the internal space and a communication hole, and the frame is provided with a communication surface facing the communication hole. The communication surface comprises a sound-emitting hole and a sound pickup hole, the sound-emitting hole and the sound pickup hole are isolated from each other, and the sound-emitting hole is connected to the front cavity. The sound pickup channel and the front cavity are isolated from each other through the frame.

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.

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: A mobile terminal includes a housing and a speaker component including a speaker unit that divides a cavity of the speaker component into a front speaker box and a rear speaker box, an air vent coupled to an inner cavity of the housing is disposed on a wall of the rear speaker box, and a flexible sound absorbing member that can absorb a sound and damp vibration is disposed on a wall of the inner cavity of the housing.
