WIPO Patent Application WO/2020/220704
Kind Code:
A1
Abstract:
Disclosed in the present invention are a diaphragm, a loudspeaker, and a loudspeaker module, wherein the diaphragm comprises a central part and an annular hanging part which is arranged around the central part and can generate elastic deformation; the central part is of a flat plate structure; the hanging part comprises an inner edge part, an outer edge part, and a deformation part located between the inner edge part and the outer edge part; the inner edge part is fixedly connected to the edge of the central part, and the outer edge part at least comprises a flat plate edge part in the same extending direction as the central part; the deformation part is of a flat plate structure having the extending direction the same as that of the central part, or the deformation part is of a structure which deviates from the horizontal center line of the edge part of the flat plate and protrudes upwards and/or protrudes downwards by not more than 0.2 mm. The technical solutions of the present invention can reduce the height of the loudspeaker.
