Title:
WATERPROOF LOUDSPEAKER VIBRATING DIAPHRAGM AND LOUDSPEAKER
Document Type and Number:
WIPO Patent Application WO/2022/252553
Kind Code:
A1
Abstract:
Disclosed is a waterproof loudspeaker vibrating diaphragm, comprising a vibrating diaphragm body (1), wherein the vibrating diaphragm body (1) is sequentially provided with a center portion (2), a folded ring portion (3) and a fixing portion (4) from inside to outside; the center portion (2) is provided with a vibrating plate (5) matching the center portion; a top end of the folded ring portion (3) is provided with a vibrating diaphragm carrier ring (6) arranged on the vibrating plate (5) in a sleeved manner; and synthetic resin (7) which is connected to the vibrating diaphragm carrier ring (6) is arranged at a top end of the fixing portion (4). An edge of the folded ring portion forms a cofferdam, glue is coated on an inner wall of the cofferdam, the inner wall of the cofferdam is attached to an outer edge of a front cover, and owing to the fluidity of the glue, the glue can automatically gather downwards to avoid generating air holes, such that a root of the inner wall of the cofferdam and the bottom of the outer edge of the front cover are reliably sealed. Further disclosed is a loudspeaker, which comprises a base frame (8) arranged on the vibrating diaphragm body (1) in a sleeved manner, wherein a supporting assembly (9) matching the base frame (8) is arranged outside the base frame in a sleeving manner, such that mounting and dismounting of the base frame of the loudspeaker are facilitated.
