Specific embodiment
The invention will be further described for embodiment shown in reference to the accompanying drawing:
Embodiment one: referring to figure 1, the put more energy into key step of diaphragm structure manufacturing method of the present invention is described as follows:
Step S1 is first carried out, a surface of sheet material of putting more energy into equably is coated with a hot melt adhesive layer in a manner of roller coating, and
It is selectively coated with one on another surface of the sheet material relative to hot melt adhesive layer in a manner of roller coating again putting more energy into and puts more energy into colloid layer, with
It puts more energy into the rigidity of sheet material.Hot melt adhesive can be selected from general common material, such as: vinyl polymer, polyvinyl alcohol.And add
Such as heat-curable glue, UV cured glue can be used in strength colloid layer, by carbon nanotubes or nano ceramic powder etc
Hard material be mixed in colloidal materials and constitute, with ultraviolet source irradiation or heated baking, this coated is finished again later
Sheet material of putting more energy into, the colloid layer that makes to put more energy into hardens and promotes the rigidity for sheet material of putting more energy into.
It is finished to hot melt adhesive layer and colloid layer hardening of putting more energy into, the sheet material that can will put more energy into cuts into proper shape (in this reality
It is round for applying in example, as shown in Fig. 2) and size.Those skilled in the art can also select the sheet material progress ruler that will put more energy into advance
It is very little and shape to cut operation, without that should be limited with the present embodiment.I.e. executable step S2, the sheet material that will put more energy into are placed on vibration later
In film former material, is fixed using localization tool (figure is not painted) and put more energy into sheet material and vibrating diaphragm former material and make hot melt adhesive layer and vibrating diaphragm former material
It is in contact.Vibrating diaphragm former material is sent in heating furnace with sheet material of putting more energy into later and is toasted, hot melt adhesive layer is melted and binds vibration
Film former material.
Bonding, which is completed, can be taken off, and can carry out step S3 later, the compacting tool set for shaping vibrating diaphragm using one, with hot pressing
The mode of molding or air-pressure forming suppresses the vibrating diaphragm former material after being fixed and binded by localization tool and sheet material of putting more energy into, and makes
Formation have central portion 11 and outstanding edge 12 vibrating diaphragm 1 (as shown in Fig. 2), in the present embodiment, sheet material of putting more energy into only covers
In central portion 11.
Since sheet material of putting more energy into is to be pre-coated with hot melt adhesive layer in step S1, and be just placed in vibrating diaphragm former material later
Carry out heating bonding again, as long as therefore glue-line is equably to be coated with and bondline thickness should not be too thick, be not easy on processing procedure
The excessive or very few problem of glue amount occurs, therefore compared to traditional preparation method, the thickness that the present invention heats glue amount is with the uniformity
Compare preferable control.Furthermore also because in being in step s3 just pressed into the vibrating diaphragm former material after bonding with sheet material of putting more energy into
Type, vibrating diaphragm former material are structure of the flat sheet body without forming so-called central portion 11 and outstanding side before compaction, and
It is in the overall structure for being finally just formed simultaneously vibrating diaphragm 10 in a manner of compression moulding.Compared to the manufacturing method of traditional vibrating diaphragm,
The present invention is relatively easy many on processing procedure the problem of eliminating vibrating diaphragm former material on processing procedure and putting more energy into sheet material positioning,
Help to promote yield.
It should be noted that selecting in a manner of roller coating applying hot melt adhesives layer in step sl with colloid layer of putting more energy into is to allow
Glue-line can be equably coated with, and those skilled in the art are to can choose other common coating methods without with the present embodiment
It is limited.In addition, those skilled in the art also can choose the dedicated jig of positioning and go to put more energy into step S2 or step S3
The fixation of sheet material and vibrating diaphragm former material, using this to reach sheet material of putting more energy into is in the position of central point.
Vibrating diaphragm former material and sheet material of putting more energy into is allowed to use identical material in addition, those skilled in the art also can choose.In this way,
Because vibrating diaphragm former material is identical as the material properties for sheet material of putting more energy into, it is more conducive to be integrated the two more closely bonding.
As shown in Fig. 3 according to vibrating diaphragm 1 manufactured by above-mentioned preparation method, vibrating diaphragm 1 includes general rounded vibrating diaphragm former material
10 and sheet material 20 of putting more energy into.Wherein vibrating diaphragm former material 10 has central portion 11 and surrounds and connect the outstanding edge 12 of central portion 11.
The put more energy into top surface of sheet material 20 is coated with and puts more energy into colloid layer 30 and bottom-surface coated has a hot melt adhesive layer 40, and sheet material 20 of putting more energy into passes through
40 gluing central portion 11 of hot melt adhesive layer.
The above embodiments merely illustrate the technical concept and features of the present invention, and its object is to allow person skilled in the art
Scholar cans understand the content of the present invention and implement it accordingly, and it is not intended to limit the scope of the present invention.It is all according to the present invention
Equivalent change or modification made by Spirit Essence, should be covered by the protection scope of the present invention.
