Abstract
Disclosed in the present disclosure are a dome and a diaphragm assembly for a sound producing apparatus, a sound producing apparatus, and an electronic device. The dome comprises an organic aerogel matrix and a reinforcing material dispersed in the organic aerogel matrix. The mass of the organic aerogel matrix accounts for 10% to 95% of the total mass of the dome, and the modulus density ratio of the dome is greater than or equal to 5 GPa·cm/g. According to the present disclosure, the dome has a light weight, and thus facilitates meeting the design requirements of lightening, thinning and miniaturization of the sound producing apparatus, and can also reduce the resonance frequency of the sound producing apparatus and improve the medium-frequency sensitivity thereof.
