Size, to adapt to different sounding monomers.
In one example, as shown in Figures 2 and 4, the entirety of sounding monomer is in rectangular parallelepiped structure.Slot 25 is located at cuboid knot
On the long side of structure.Long side refers to the biggish side of length in the side of rectangular parallelepiped structure.Usual sounding monomer is in flat
Structure.Size on direction of vibration is minimum.Long side is that sounding monomer is longer in perpendicular to the orthographic projection on direction of vibration
Side.Long side has bigger space, and it is bigger that this does slot 25, and the sounding effect of sounding monomer is more preferable.
Correspondingly, in this example embodiment, the overall structure of shell 27 is also in rectangular parallelepiped structure.The bottom and side wall portion of magnetic yoke 17
23 surround approximate rectangular parallelepiped structure.In this example embodiment, it is arranged jagged 24 at the middle part of the long side of shell 27.
In one example, the slot 25 being provided at notch 24 is even number, and is symmetrically disposed in shell 27 two-by-two
Opposite two sides.In this way, vibratory flow can prevent vibrating diaphragm 13 from polarizing more uniformly to outer propagation.
As shown in Fig. 1,4,8 and 9, slot 25 is provided in the middle part of two long sides of shell 27.The position of slot 25 is opposite,
It is equal in magnitude.In this way, vibrating diaphragm 13, in vibration, the air-flow inside sounding monomer can be flowed out via the slot 25 of two sides, compared to only
Slot 25 is set in side, the active force for the air pressure that vibrating diaphragm 13 is subject to is more balanced, is not susceptible to polarize.
Those skilled in the art can be set according to actual needs the shape of slot 25, quantity etc..
In other examples, slot 25 also can be set in the short side of rectangular parallelepiped structure.Short side refers to long in side
Spend lesser side.Damper assembly is set at notch 24.
In one example, for example, as shown in Fig. 3,5 and 6, support construction includes first connecting portion 21, second connecting portion
22 and between first connecting portion 21 and second connecting portion 22 go out part 20.The outer surface of part 20 and sounding monomer out
Bottom or side at setting angle.Part 20 out is provided with through-hole 28.First connecting portion 21 is connect with shell 27.For example,
First connecting portion 21 is bonded on shell 27 by binder.Second connecting portion 22 is connect with magnetic yoke 17.Wherein, pass through bonding
Second connecting portion 22 is bonded in magnetic yoke 17 by agent.Out the angle between part 20 and first connecting portion 21 and out part 20 with
Angle between second connecting portion 22 is in obtuse angle.The set-up mode of two interconnecting pieces makes the fixation of support construction more firm
Gu.
In addition, the handling ease of the support construction.It can be, sheet metal is integrally formed system by stamping forming mode
Support construction out.The mode for being also possible to plastic raw materials injection molding, which is integrally formed, produces support construction.
Preferably, as shown in figure 3 and 9, at the position that shell 27 and first connecting portion 21 cooperate and in magnetic yoke 17 and second
Recessed portion 30 is formed at least one of position that interconnecting piece 22 cooperates.In first connecting portion 21 and second connecting portion 22 extremely
Few one is embedded in corresponding recessed portion 30.
Specifically, recessed portion 30 is the Step-edge Junction formed by the surface indentation of the side of the bottom or shell 27 of magnetic yoke 17
Structure.First connecting portion 21 and second connecting portion 22 are bonded on the step surface of corresponding step structure by binder.For example,
The bottom of magnetic yoke 17 and the side of shell 27 are provided with recessed portion, and first connecting portion 21 and second connecting portion 22 are embedded in recess
In portion；The side of the bottom of magnetic yoke 17 or shell 27 is either provided with recessed portion, the first connection corresponding with recessed portion
Portion 21 or second connecting portion 22 are embedded in recessed portion.By the way that recessed portion 30 is arranged, first connecting portion 21 and/or second are saved
Space shared by the thickness of interconnecting piece 22 can be such that the volume of sounding monomer does smaller.
In one example, as shown in Figures 3 and 5, damper assembly includes the benefit for covering the edge of support construction and screen cloth 18
Strong layer.Strengthening course can protect the edge of support construction and screen cloth 18, and can be improved the bonding strength of the two.For example, reinforcement
Layer is the injection molding material 29 formed by way of injection molding.In production, steel disc is subjected to bending first to form bending steel disc 19.
Then, through-hole 28 is stamped and formed out in the part 20 that goes out of bending steel disc 19.Next, screen cloth 18 is covered out part 20, screen cloth
18 edge is bonded by binder and part 20 out.Finally, injection molding material 29 is molded into bending steel disc by the way of injection molding
On the 19 and edge of screen cloth 18.Injection molding material 29 makes screen cloth 18 and the connection of support construction stronger, improves sounding list
The reliability of body.
In other examples, first screen cloth 18 can be bonded with steel disc, then by injection molding material 29 by way of injection molding
It is molded on bending steel disc 19 and on the edge of screen cloth 18, steel disc is finally subjected to bending to form the angle of setting.
Optionally, screen cloth 18 be located at the close magnetic circuit system of support construction surface, far from magnetic circuit system surface or
