Embodiment
Further detailed description is done to the present invention with specific embodiment below in conjunction with the accompanying drawings.
Embodiment one：
As depicted in figs. 1 and 2, the diaphragm of loudspeaker 1 includes centrally located plane top dome portion II, and is located at
The ring portion I at top dome portion II edges, ring portion I are the curved-surface structure of arc, as depicted in figs. 1 and 2.The downside of vibrating diaphragm 1 combines
There is voice coil loudspeaker voice coil 2, voice coil loudspeaker voice coil 2 is electrically connected with external circuit, and voice coil loudspeaker voice coil 2 is connected after electric signal in magnetic circuit system（Do not shown in figure）The magnetic of formation
Stress up-down vibration in gap, it is further driven to the vibration of vibrating diaphragm 1 and produces sound.During the up-down vibration of vibrating diaphragm 1, the meeting of vibrating diaphragm 1
Screen resilience is produced, enables the vibration of vibrating diaphragm 1 normally repeatedly.
As shown in Figures 2 and 3, the present embodiment vibrating diaphragm 1 by two layers of substrate layer 11 and is incorporated between two layers of substrate layer 11
The secure bond of glue-line 10, its mesoglea 10 is UV glue-lines.UV glue is optic-solidified adhesive, uncured viscosity very little before, through UV
It is curable after light irradiation.UV light irradiations are carried out after UV glue is applied between two layers of substrate layer 11, can be by two layers of base material after UV adhesive curings
Layer 11 is firmly combined as a whole.Preferably, two layers of substrate layer 11 is transparent material, in order to absorption of the UV glue to light.
Two layers of substrate layer of the present embodiment 11 is identical material, is PEEK（Polyether-ether-ketone）、PET（Polyethylene terephthalate）、
PEI（Etherimide）Or PAR（Polyarylate）In one kind, above-mentioned material is transparent material, and intensity and resilience are preferable.
The vibrating diaphragm of this structure, including two layers of substrate layer, and by UV glue secure bonds between two layers of substrate layer 11, by
It is easier to be bonded with UV glue-lines during viscosity is small before UV adhesive curings, thus two layers substrate layer 11 is laminating mutually, does not allow
Bubble is also easy to produce, and the fastness combined between the high substrate layer of UV light irradiation solidify afterwards degree is good, is shaken so as to advantageously ensure that
The stability of film.Vibrating diaphragm uses the structure of this UV glue-lines, and the bulk strength of vibrating diaphragm can get a promotion after curable adhesive layer, can be with
Film is avoided the occurrence of to discount as being advantageous to be lifted the resilience effect of vibrating diaphragm, so as to ensure the sounding effect of vibrating diaphragm, improving the sound of vibrating diaphragm
Learn performance.
The manufacture method of the diaphragm of loudspeaker of this band UV glue-lines is as follows：
A, by coating UV glue-line between two substrate layers 11, form a preliminary diaphragm；
B, the UV glue-lines in above-mentioned diaphragm are subjected to precuring；
C, above-mentioned diaphragm is compressing, form vibrating diaphragm；
D, UV glue-lines ongoing to vibrating diaphragm are fully cured.
Wherein, the precuring of UV glue-lines is through short irradiation by diaphragm by the UV light of small energy in above-mentioned steps b
Formed, now UV glue-lines still have certain trickling property, and precuring is advantageous in step c to the compressing of vibrating diaphragm.Step
The compressing process of vibrating diaphragm is that diaphragm is pressed into the process in top dome portion and ring portion in rapid c, and now UV glue has carried out pre- solid
Change, colloid skewness will not be caused by force very much because of the mobility of UV glue in compressing process.Using big in step d
The UV light of energy is irradiated to UV glue-lines, and after UV glue-lines are fully cured, glue-line has stable shape and good elasticity, can
To avoid vibrating diaphragm from film folding occur, make vibrating diaphragm that there is good resilience effect.Simultaneously this UV glue curing mode make substrate layer it
Between cohesive force get a promotion, make the stability of vibrating diaphragm higher.
By UV glue secure bonds between substrate layer of the present invention, with good trickling property when UV glue is uncured, be advantageous to
Substrate layer is laminating with UV glue-lines；And there is good elasticity after UV adhesive curings, be less prone to film discount as.Because UV glue has
Two kinds of forms, therefore can have trickling property good simultaneously and the advantages of elasticity good colloid, be advantageous to improve the globality of vibrating diaphragm
Energy.

As shown in figure 4, the present embodiment vibrating diaphragm has three layers of substrate layer：One layer of substrate layer 11 and two layers of substrate layer 12, arbitrarily
By the secure bond of glue-line 10 between two layers adjacent of substrate layer, its mesoglea 10 is UV glue-lines.Substrate layer 11 and substrate layer 12
It is transparent configuration, respectively different material, it is preferred that material PEEK（Polyether-ether-ketone）、PET（Poly terephthalic acid second
Diol ester）、PEI（Etherimide）Or PAR（Polyarylate）In any two kinds.Because substrate layer 11 and two layers of substrate layer 12 are
Transparent material, therefore be advantageous to UV light and be irradiated to UV glue through substrate layer, be advantageous to the solidification of UV glue.
The manufacture method of the present embodiment diaphragm of loudspeaker is same as above an embodiment, be in step a simply by three layers of substrate layer it
Between pass through UV glue-line secure bonds.Between two layers of substrate layer of the present embodiment arbitrary neighborhood by UV glue secure bond be one
Body, the vibrating diaphragm of this structure can ensure the stability of vibrating diaphragm, prevent vibrating diaphragm from film occur and discounting as being advantageous to lift returning for vibrating diaphragm
Effect is played, ensures the sounding effect of vibrating diaphragm, so as to improve the acoustical behavior of vibrating diaphragm.
Embodiment three：
As shown in figure 5, the present embodiment vibrating diaphragm has three layers of substrate layer：One layer of substrate layer 11 and two layers of substrate layer 12, wherein,
By the secure bond of UV glue-lines 10 between adjacent substrate layer 11 and substrate layer 12, by general between adjacent two layers of substrate layer 12
The logical secure bond of glue-line 10 '.Same above example, three layers of substrate layer are transparent material, and use two kinds of different materials, this
Outside, common glue-line 10 ' is also transparent material, in order to UV light irradiations.
In the manufacturing step of the present embodiment diaphragm of loudspeaker, step a is first that two substrate layers 12 and common glue-line 10 ' are fixed
With reference to then the coating UV glue-line 10 between adjacent substrate layer 12 and substrate layer 11, is with the difference of above example
Also include the step of adjacent two substrate layer 12 is with the common secure bond of glue-line 10 '.
This diaphragm structure of the present embodiment can equally ensure the stability of vibrating diaphragm, prevent vibrating diaphragm occur film discount as,
Be advantageous to be lifted the resilience effect of vibrating diaphragm, ensure the sounding effect of vibrating diaphragm, so as to improve the acoustical behavior of vibrating diaphragm.
Additionally, this invention is not limited to above three embodiment, the selection of substrate layer material be not limited to above-mentioned PEEK, PET,
These four materials of PEI or PAR, or other materials, as long as using UV glue between adjacent two substrate layer；Using three layers of base
During material layer, the material of three layers of substrate layer can be with different, i.e., using three kinds of different substrate layer materials, and material is transparent knot
Structure.
Under the above-mentioned teaching of the present invention, those skilled in the art can carry out others on the basis of above-described embodiment
Improve and deform, and these are improved and deformation, are all within the scope of the present invention, it will be understood by those skilled in the art that
