[specific embodiment]
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describing, it is clear that described embodiment is only a part of the embodiment of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
All other embodiment obtained, fall within the protection scope of the utility model.
It please refers to Fig.1 to Fig.3, the utility model provides a kind of vibrating diaphragm 1 comprising centrally located top dome portion
10, the ring portion 30 around the top dome portion 10 and the fixed part 50 that is extended outward from the outer peripheral edge in the ring portion 30.?
In the visual angle of Fig. 1, the shape that the top dome portion 10, the ring portion 30 and the fixed part 50 collectively constitute is generally rectangular
Shape.
33, connection phase when two short axles that the ring portion 30 includes two long axis being oppositely arranged while 31, is oppositely arranged
The adjacent long axis 33 corner part 35 and is set to the long axis at 31 and/or the short axle 33 at 31 and the short axle
Recessed portion 37, the corner part 35 be equipped with fold 351.The long axis at 31 and the short axle 33 pass through the corner part 35
Successively connect and surrounds cyclic structure.In the visual angle of Fig. 1, the protrusion direction in the ring portion 30 is upward, and opening direction is downward.
In the present embodiment, the width of the corner part 35 be greater than the long axis at 31 and the short axle 33 width,
The width of the corner part 35 is done greatly, rupture of membranes phenomenon occurs in corner part 35 when can prevent the vibrating diaphragm 1 from vibrating.
The long axis at 31 and/or the short axle 33 be equipped with the recessed portion 37, the recessed portion 37 is by the long axis
At 31 and/or the short axle, 33 opening direction towards the ring portion 30 is recessed to be formed, i.e., by the long axis side 31 and/or
The opening direction in surface towards the ring portion 30 of opening of the short axle side 33 far from the ring portion 30 is recessed to be formed.Institute
The recess direction of recessed portion 37 and the protrusion direction in the ring portion 30 are stated on the contrary, in the visual angle Fig. 1, the recessed portion 37 it is recessed
It is downward to fall into direction.By the way that the recessed portion 37 is arranged, the ring height at this can be reduced, compared with the relevant technologies, when press mold
Thickness at this thickens, and in the case where same target resonant frequency f0 to be obtained, low stretching press mold can be used, reliability is more
It is high；And after reducing ring height, resonant frequency f0 can be lower, and when being applied to loudspeaker, low frequency performance is more preferable.
In the present embodiment, the quantity of the recessed portion 37 is two, is divided into two short axle sides 33.
Further, two recessed portions 37 are symmetrical arranged about the central axes of 1 width direction of vibrating diaphragm.
Further, the recessed portion 37 is located at the middle position on the short axle side 33, and in the recessed portion 37
Vertical line and the perpendicular bisector on the short axle side 33 are located along the same line.In press mold molding, the middle position on the short axle side 33
What can be drawn is thinner, and recessed portion 37, which is set at this, may further ensure that reliability.
Further, the outer profile of the recessed portion 37 is oval or round, when the recessed portion is ellipse, institute
