Abstract

The present invention discloses a vibrating diaphragm, the vibrating diaphragm comprises an elastomer layer. A method for preparing the elastomer layer comprises: adding a nano silicon dioxide to an organic solvent and performing a dispersion treatment to form a first mixed liquid; mixing a polyol, the organic solvent and a catalyst to form a second mixed liquid; mixing the first mixed liquid andthe second mixed liquid to form a third mixed liquid; adding a polyisocyanate to the third mixed liquid, and mixing uniformly; adding a chain extender to the third mixed liquid added with the polyisocyanate and uniformly mixed to form a polymer solution; curing the polymer solution.

Description

technical field [0001] The present invention relates to the technical field of electroacoustic conversion, and more specifically, to a vibrating membrane. Background technique [0002] In existing loudspeakers, the diaphragm mostly uses high-modulus plastic substrate layers (for example, PEEK, PAR, PEI, PI, etc.), conventional elastomer material layers (for example, silicone rubber, TPU, TPEE, TPS, etc.) and A single-layer or multi-layer composite structure of the damping glue layer (for example, acrylic glue, silica gel, etc.). With the increasing requirements for ultra-thin, high-power, waterproof and high-quality sound of speakers, higher requirements are put forward for the thickness, resilience, and temperature resistance of the speaker diaphragm. [0003] When the plastic substrate layer is used as the supporting material of the diaphragm, since the material is in a glass state at room temperature, the chain segments cannot move, so the resilience and damping properti...
