Abstract

The invention provides a vibrating diaphragm assembly forming method of a sound production device, and the vibrating diaphragm assembly comprises a vibrating diaphragm body and an auxiliary assembly.The method comprises the steps: providing a forming die, and an inner cavity of the forming die being provided with an inner cavity surface; providing an auxiliary assembly, wherein the surface of theauxiliary assembly is provided with a micro-nano structure; the auxiliary assembly being arranged in a forming mold, and the surface, provided with the micro-nano structure, of the auxiliary assemblyand the inner cavity surface forming a forming surface used for forming the vibrating diaphragm body; filling an inner cavity of the forming mold with a vibrating diaphragm body material, manufacturing a vibrating diaphragm body, and the surface, provided with the micro-nano structure, of the auxiliary assembly being connected with the vibrating diaphragm body; and demolding the vibrating diaphragm body and the auxiliary assembly. The invention further provides a vibrating diaphragm assembly formed by using the forming method and a sound production single body with the vibrating diaphragm assembly. The vibrating diaphragm assembly obtained through the forming method of the vibrating diaphragm assembly has high strength and small deformation shrinkage amount, and the assembled sound production single body has good waterproof sealing performance and excellent acoustic performance.

Description

technical field [0001] The present invention relates to the technical field of acoustics, and more specifically, the present invention relates to a method for forming a diaphragm assembly of a sound generating device, a diaphragm assembly and a sound emitting unit. Background technique [0002] As a device that converts electrical energy into sound energy, the speaker is widely used in mobile terminals such as mobile phones, computers, and pads. The performance of the device directly affects the sound playback effect of the terminal device. As one of the key components of loudspeaker sound production, the diaphragm has higher and higher requirements, and gradually develops in the direction of high strength, high sound quality, and high waterproof and airtightness. [0003] Rubber materials represented by silica gel have gradually become the special material for speaker diaphragms. Silicone is also the preferred material for speaker waterproofing due to its high fluidity, hi...
