Loudspeaker assembly, sound generating apparatus and electronic device

A sound generating apparatus, comprising:

• a front shell and a back shell, engaged with each other to define a chamber;
• a support, received in the chamber;
• a loudspeaker body, received in the chamber and disposed between the support and the back shell, wherein the loudspeaker has a sound radiation face for transmitting sound radiation to an outside of the sound generating apparatus, the sound radiation face faces the front shell;
• and
• a magnetic shielding cover, received in the chamber and disposed between the support and the front shell,
• wherein the magnetic shielding cover defines a sound transmission hole;
• the magnetic shielding cover has a first portion close to a periphery of the sound transmission hole and a second portion away from the periphery of the sound transmission hole;
• the first portion has a first magnetic induction, the second portion has a second magnetic induction, the first magnetic induction is greater than the second magnetic induction.
