Abstract

The present disclosure provides an alkali metal-modified acoustic reinforcing material, a production method thereof, a speaker and an electronic device. The alkali metal-modified acoustic reinforcing material is prepared by homogeneously mixing an alkali metal-modified molecular sieve, a binder, a dispersant and an auxiliary agent and then shaping; wherein the content of the alkali metal-modified molecular sieve is not less than 70%, the content of alkali metal is 0.001-1.45%, the dry basis content of the dispersant is 0-1%, and the dry basis content of the auxiliary agent is 0-15%, based on 100% of the total weight of the alkali metal-modified acoustic reinforcing material. Compared with the acoustic reinforcing materials prepared from an unmodified molecular sieves as a raw material, the alkali metal-modified acoustic reinforcing material provide by the present disclosure has less adsorption of water and VOC, which can substantially improve its stability and reliability in terms of acoustic performance, and also improve its basic acoustic performance to some extent.
