Abstract

The invention provides a preparation method and device for an electrostatic speaker diaphragm, which relates to the technical field of electronic equipment, including: sequentially covering graphene and P solution on copper foil to obtain a target whose surface is covered with graphene film and P film Copper foil; perform etching treatment and initial surface treatment on the target copper foil in sequence to obtain the initial speaker diaphragm; perform square resistance surface treatment on the initial speaker diaphragm to obtain the target speaker diaphragm; place the target speaker diaphragm on the first preset In the environment, the target speaker diaphragm is polarized to obtain the electrostatic speaker diaphragm, which solves the technical problems of edge vibration distortion and phase lag of the electrostatic speaker diaphragm in the prior art.

Description

technical field [0001] The invention relates to the technical field of electronic equipment, in particular to a method and a device for preparing an electrostatic loudspeaker diaphragm. Background technique [0002] The biggest advantage of the electrostatic speaker is: the diaphragm is extremely light, so it has excellent flexibility and resolution, and can capture extremely subtle changes in the music signal, making people feel very realistic and present, and can fully express the charm of music. . Its specific performance is: [0003] First, the quality of the diaphragm is extremely light, so the electrostatic field speaker has an excellent high-frequency frequency response (up to 40KHz or more). [0004] Second, the vibration system of the electrostatic speaker is a composite diaphragm. The mass is hundreds of times lighter than the vibration system of the dynamic speaker, and the transient characteristics are naturally much superior to the dynamic speaker. [0005] ...
