WIPO Patent Application WO/2018/214785
Kind Code:
A1
Abstract:
Disclosed are a vibrating diaphragm and a miniature sound generator provided with the vibrating diaphragm, relating to the technical field of electroacoustic products. The vibrating diaphragm comprises a central portion, an edge portion and a fixed portion connected from inside to outside in sequence, wherein the edge portion comprises arc-shaped corners, and a first side and a second side connected by the arc-shaped corners; patterns are distributed on the arc-shaped corners; in an orthographic projection plane of the vibrating diaphragm, the patterns comprise at least one curve-shaped pattern; each curve-shaped pattern extends from the adjacent first side of the edge portion to the second side; and the curve-shaped patterns on each of the arc-shaped corners are arranged from an inner side to an outer side of the arc-shaped corner in sequence. According to the vibrating diaphragm and the miniature sound generator provided with the vibrating diaphragm, the vibrating diaphragm vibrates stably, the compliance is high, wrinkles will not easily be generated, and the anti-fatigue capability is strong, so that the miniature sound generator has high sensitivity, small distortion, high sound quality and a high reliability margin.
