Detailed Description

As shown in fig. 1-2, a strip-shaped corrugated reinforced waterproof diaphragm includes a diaphragm main body, where the diaphragm main body is formed by integrally molding a piece of paperboard, and as shown in fig. 1, the diaphragm main body includes a dome area 1 located at the center and an inclined bowl wall area 2 located at the periphery of the dome area 1, where the dome area 1 is an upward convex portion in the middle and the bowl wall area 2 is an inclined portion around the dome area. The paper board forming the vibrating diaphragm main body is bent inwards at the basin wall area 2 to form a plurality of folds 3 extending vertically along the basin wall area 2, the folds 3 are gradually widened from bottom to top,

the utility model discloses it is especially peculiar that, the position that 2 surfaces in basin wall district are relative with fold 3 is provided with strengthens card 4, as shown in fig. 4, is the enhancement card 4 structure in a preferred embodiment promptly, strengthen card 4 and include the bounding wall 5 with the identical three horn shapes of 2 radians in basin wall district, bounding wall 5 is attached at the surface in basin wall district 2 to bond with basin wall district 2. The center of the inner surface of the enclosing plate 5 is provided with a clamping head 6 extending along the length direction of the enclosing plate 5, the clamping head 6 is matched with the folds 3 and is also of a structure with one end gradually widened towards the other end, and the clamping head 6 is clamped in the folds 3 and is bonded with the folds 3.

The utility model discloses a form fold 3 in basin wall district 2, fold 3 self just can play the additional strengthening to basin wall district 2, simultaneously, through strengthen card 4 in 3 embeddings of fold, strengthen card 4 and can make fold 3 more stable, further promoted the intensity of vibrating diaphragm main part. The coaming 5 can effectively ensure the adhesiveness of the reinforcing card 4 on the basin wall area 2.

On this basis, in order to be further right the utility model discloses a structural strength promotes, accessible beaded finish 7 forms each to strengthen the card 4 and connects to make each strengthen the card 4 and constitute an organic whole, as shown in fig. 3, the periphery of basin wall district 2 still is provided with multichannel beaded finish 7, beaded finish 7 is connected with strengthening the card 4, generally the quantity of beaded finish 7 is twice at least.
