Abstract
A loudspeaker assembly and an electronic device are provided. The loudspeaker assembly includes: a loudspeaker body and a magnetic shielding cover. The magnetic shielding cover is arranged at a side of a sound radiation face of the loudspeaker body and defines a sound transmission hole. The magnetic shielding cover is a ferromagnetic cover. The magnetic shielding cover is configured to prevent at least partial magnetic flux at the side of the sound radiation face of the loudspeaker body from passing through the magnetic shielding cover and conduct the at least partial magnetic flux to an inertial magnetic field of the loudspeaker body. Magnetic induction of a portion of the magnetic shielding cover away from a periphery of the sound transmission hole is greater than that of a portion of the magnetic shielding cover close to the periphery of the sound transmission hole.
