The invention discloses a preparation method of a diaphragm and a sounding device. The preparation method comprises: adding a short fiber material and a reinforcing filler to the silicone rubber raw material, and mixing uniformly, wherein the reinforcing filler is at least one of spherical particles and spheroidal particles; and mixing the mixed materials Coformed to form a diaphragm. The addition of at least one of spherical and spheroidal reinforcing fillers to the silicone rubber raw material can effectively reduce the orientation of the short fiber material in the silicone product, reduce the internal stress and anisotropy of the diaphragm, and warpage. |
