Abstract

The invention provides a method for forming a diaphragm assembly of a sounding device. The diaphragm assembly includes a diaphragm body and an auxiliary assembly, including: providing a molding mold, the inner cavity of which has an inner cavity surface; providing an auxiliary assembly, assisting The surface of the component is provided with micro-nano structure; the auxiliary component is set in the molding mold, and the surface of the auxiliary component with the micro-nano structure and the inner cavity surface constitute the molding surface for molding the diaphragm body; in the inner cavity of the molding mold The material of the diaphragm body is filled to form the diaphragm body, and the surface of the auxiliary component with the micro-nano structure forms a connection with the diaphragm body; the diaphragm body and the auxiliary component are demolded. The present invention also provides a diaphragm assembly formed by the above forming method and a sound emitting unit with the diaphragm assembly. The diaphragm assembly obtained by the molding method of the diaphragm assembly of the present invention has high strength and small deformation and shrinkage, and the assembled sounding unit has good waterproof and 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...
