Title:
VIBRATING DIAPHRAGM AND LOUDSPEAKER
Document Type and Number:
WIPO Patent Application WO/2021/147492
Kind Code:
A1
Abstract:
Provided in the present invention is a vibrating diaphragm, comprising a vibrating diaphragm main body, wherein the vibrating diaphragm main body comprises a fixed part on the outer side thereof, a bendable ring part which is arranged on the inner ring side of the fixed part in a protruding manner and which can generate elastic deformation, and an inner side part which is arranged on the inner ring side of the bendable ring part; and the vibrating diaphragm main body is made of a waterproof breathable material with waterproof breathable micropores. Further provided in the present invention is a loudspeaker with the diaphragm. According to the technical scheme of the present invention, the vibrating diaphragm main body is made of the waterproof breathable material with the waterproof breathable micropores, the vibrating diaphragm main body is provided with the micropores, and the sizes of the micropores are between those of water molecules and air molecules, such that air molecules can smoothly pass through the vibrating diaphragm; at the same time, the water molecules can be effectively blocked from passing therethrough, the vibrating diaphragm has waterproof and breathable functions, the internal and external air pressures of the loudspeaker are balanced, and the waterproof performance of the loudspeaker can also be improved. Meanwhile, the vibrating diaphragm itself forms waterproof breathable micropores, so that large vent holes are prevented from being formed, an additional waterproof net is prevented from being bonded, and the sound production performance of the vibrating diaphragm is guaranteed.
