Title:
NOVEL VIBRATING DIAPHRAGM
Document Type and Number:
WIPO Patent Application WO/2022/000601
Kind Code:
A1
Abstract:
The present scheme provides a novel vibrating diaphragm, comprising a central portion, a peripheral portion, and a bent ring portion connected to the central portion and the peripheral portion, characterized in that the bent ring portion comprises a first bent ring, a second bent ring, and a connecting portion connected to and located between the first bent ring and the second bent ring. The first bent ring comprises a first edge end connected to the central portion and a second edge end connected to the connecting portion. The second bent ring comprises a first peripheral end connected to the connecting portion and a second peripheral end connected to the peripheral portion. The first bent ring and the second bent ring are raised in the same direction. The present utility model has a markedly different structure compared to vibrating diaphragms in the prior art. Specifically, the bent ring portion is divided into the first bent ring and the second bent ring, and the bent ring portion formed from the first bent ring and the second bent ring has a greater amplitude with a smaller overall width, thereby meeting corresponding acoustic performance requirements.
