It illustrates outside, the component and the positioned opposite of step, numerical expression and numerical value otherwise illustrated in these embodiments is unlimited
The scope of the utility model processed.Be to the description only actually of at least one exemplary embodiment below it is illustrative, never
As to the utility model and its application or any restrictions used.
Technology and equipment known to person of ordinary skill in the relevant may be not discussed in detail, but in appropriate situation
Under, the technology and equipment should be considered as part of specification.In shown here and discussion all examples, any tool
Body value should be construed as merely illustratively, not as limitation.Therefore, other examples of exemplary embodiment can have
There is different values.It should also be noted that similar label and letter indicate similar terms in following attached drawing, therefore, once a certain item
It is defined in an attached drawing, then in subsequent attached drawing does not need that it is further discussed.
Fig. 1, Fig. 3 and Fig. 4 show the structural schematic diagram of the sounding device monomer of an embodiment of the present invention offer.Such as
Shown in Fig. 1, which includes vibrating diaphragm 1 and voice coil 2；Voice coil 2 includes the voice coil ontology 21 of annular and from voice coil
The lead 22 that the same side of ontology 21 is drawn；Voice coil ontology 21 include positioned at 22 extraction location of lead outlet side 211 and with
The opposite free side 212 of outlet side 211；Vibrating diaphragm 1 includes central part 11 and the ring portion 12 around 11 periphery of central part；Voice coil 2
It is connect with the central part 11 of vibrating diaphragm 1；Ring portion 12 includes first part 121 corresponding with the outlet side 211 of voice coil 2, and and sound
The corresponding second part 122 of free side 212 of circle 2；The thickness of the first part 121 in ring portion 12 is less than the second of ring portion 12
The thickness of part 122.
In technical solution provided by the embodiment of the utility model, by vibrating diaphragm ring portion close to the first of voice coil leads outlet side
Part is arranged thinner, the thickness that vibrating diaphragm ring portion is arranged far from the second part of voice coil leads outlet side passes through
Reduction processing and/or second part to first part thicken processing, so that the vibrating diaphragm screen resilience and vibrating diaphragm of first part are drawn
Power is respectively smaller than the vibrating diaphragm screen resilience and vibrating diaphragm pulling force of second part, with balance brought by pulling force of the lead to first part by
Power difference, and then polarization problem is avoided, improve acoustical behavior and product reliability.
It should be added that vibrating diaphragm is located at the stress F1=voice coil driving of lead side 211 when voice coil drives vibrating diaphragm
Power-lead strain-vibrating diaphragm pulling force (symbol "-" is minus sign), vibrating diaphragm is located at the stress F2=sound of non-lead side (i.e. free side 212)
Enclose driving force-vibrating diaphragm pulling force, it is seen then that F1 is less than F2.Since lead strain can not disappear, so the vibrating diaphragm that reduce lead side is drawn
Power or the vibrating diaphragm pulling force for increasing non-lead side can be located at the thickness of lead side region by reduction vibrating diaphragm ring portion to reduce lead
The vibrating diaphragm pulling force of side, or the thickness of non-lead side region is located to increase non-lead side vibrating diaphragm and draw by increase vibrating diaphragm ring portion
Power, to balance the force difference of lead strain bring vibrating diaphragm two sides.In addition, vibrating diaphragm is located at lead side in vibrating diaphragm rebound
Stress F3=lead strain+vibrating diaphragm screen resilience (symbol "+" is plus sige), vibrating diaphragm are located at the stress F4=vibrating diaphragm rebound of non-lead side
Power, it is seen then that F3 is greater than F4, since lead strain can not disappear, so to reduce the vibrating diaphragm screen resilience of lead side or increase non-draw
The vibrating diaphragm screen resilience of line side can be located at the thickness of lead side region by reduction vibrating diaphragm ring portion to reduce the vibrating diaphragm of lead side and return
Elastic force, alternatively, being located at the thickness of non-lead side region by increasing vibrating diaphragm ring portion increases the vibrating diaphragm screen resilience of non-lead side,
To balance the force difference of lead strain bring vibrating diaphragm two sides.When it is implemented, first part and the second part in ring portion
Between thickness change can be cataclysm type or gradation type.
As shown in Figure 1,22 extraction location of lead can be located at middle position or the end positions of outlet side 211.This is practical
It is novel to be not specifically limited in this embodiment.Lead extraction location shown in FIG. 1 is located at the both ends of the outlet side 211.
In a concrete implementation structure, the first part 121 of 122 thickness of second part in ring portion 12 to ring portion 12
Thickness is gradually reduced.I.e. for the second part 122 in ring portion 12 closer to first part 121, thickness is smaller.Vibrating diaphragm ring portion
Gradient thickness mode can avoid vibrating diaphragm because of frangibility caused by thickness cataclysm or tearable ask between first part and second part
Topic.
Since the thickness difference of the first part 121 of the thickness and ring portion 12 of the second part 122 in ring portion 12 is more than one
After certainty ratio, vibrating diaphragm system two sides can be made to occur and force difference opposite before.Therefore, in the specific implementation, ring portion
The thickness of 12 second part 122 is thickeied than the thickness of the first part 121 in ring portion 12 is not more than 50%.Such as: first
Points 121 with a thickness of 0.068 ± 0.005mm, second part 122 with a thickness of 0.128 ± 0.005mm.
Further, vibrating diaphragm 1 uses air-pressure forming, yin-yang mold forming or injection molding.Specifically, it is rolled over by mechanical stretching
The first part 121 of ring portion 12 reduces the material strip thickness of first part 121, reuses air-pressure forming (i.e. B molding) later.
It is different using former, formpiston gap when yin-yang mold forming, i.e. formed product, thus 12 first part of vibrating diaphragm ring portion molded
121 is different (M molding) with the thickness of second part 122.Alternatively, direct injection molding, directly injection molding obtain ring portion 12 first
The vibrating diaphragm 1 different with 122 thickness of second part of part 121.
The strengthening course 3 for increasing vibrating diaphragm rigidity as shown in Fig. 2, central part 11 can be sticked, to improve acoustical behavior.
Specifically, above-mentioned sounding device monomer may also include that magnetic yoke 8, center magnetic conductive board 5, centring magnet 6, side magnetic conduction
Plate (not shown) and side magnet 7；Centring magnet 6 and side magnet 7 are split in magnetic yoke 8, and between side magnet 7 and centring magnet 6
Between be separated with magnetic gap；Centrally disposed side of the magnet 6 far from magnetic yoke 8 of center magnetic conductive board 5；While magnetic conductive board setting while magnet 7
Side far from magnetic yoke 8；The free end of voice coil 2 is hung in magnetic gap.The fixing end of voice coil 2 is fixed on the central part of vibrating diaphragm 1
On 11.
Wherein, magnetic yoke 8 is fixed on shell 4.Shell 4 can be both ends open structure, and magnetic yoke 8 is fixed on the of shell 4
Place open at one end, vibrating diaphragm 1 are fixed on the second end opening of shell 4.Vibrating diaphragm 1 further includes the fixation for being looped around 12 periphery of ring portion
In portion 123, fixed part 123 is fixed on the second end open end of shell 4.
Further, it is provided with decorative pattern in ring portion 12, enhances vibrating diaphragm intensity by the texture of decorative pattern, prevents vibrating diaphragm from sending out
Raw fold, improves acoustical behavior.
It should be added that in the specific implementation, vibrating diaphragm different zones can be adjusted according to the extraction location of lead
Thickness makes product line vibrating system reach active balance, solves vibrating diaphragm polarization problem, improves acoustical behavior and improvement product is reliable
