Abstract

The invention relates to the technical field of acoustoelectric equipments, in particular to a vibrating diaphragm and a loudspeaker. The vibrating diaphragm comprises at least one silicon rubber-polyester-polyether material layer and / or a silicon rubber-polyamide-polyether material layer; wherein the silicone rubber-polyester-polyether material is mainly obtained by dynamically vulcanizing silicone rubber, a polyester elastomer and a polyether elastomer; the silicone rubber-polyamide-polyether material is mainly obtained by dynamically vulcanizing silicone rubber, polyamide resin and a polyether elastomer. By adopting the silicone rubber-polyester-polyether material and / or the silicone rubber-polyamide-polyether material with the advantages of high damping, low density, smooth surface after being heated and the like, the damping, the softness and the tensile property of the vibrating diaphragm are improved, the density and the hardness of the vibrating diaphragm are reduced, and the surface of the material is smooth after being heated. Meanwhile, the material has hydrophobic and oleophobic functions and a self-cleaning effect, and is beneficial to improving the waterproof performance and oleic acid resistance of the vibrating diaphragm.

Description

Technical field [0001] The present invention relates to the technical field of electroelectric devices, and in particular, to a diaphragm and a speaker. Background technique [0002] The diaphragm is the main part of the acoustic conversion, and the diaphragm has a vital role in the sound performance of the speaker, which can determine the conversion quality of the speaker to the sound and determine the speed of the speaker and playback of music. As people improve the demand for sound quality, the diaphragm is widely concerned as the core components of the speaker. Among them, TPU materials, polyester, and polyether materials are widely used in the diaphragm due to good elasticity. [0003] However, the TPU material has a disadvantage of high temperature resistance resistance, which can be adhered by the surface of the heat, which is easy to adhere to the implant, which in turn leads to the unstable product. [0004] At the same time, although the high temperature resistance of p...
