Description
Technical field
The present invention relates to speaker technology field, more particularly to a kind of oscillating plate and its manufacture method.
Background technology
Oscillating plate is the important component of loudspeaker.Traditional oscillating plate is made up of paper pulp, this papery oscillating plate
Shortcoming is that specific modulus is small, easy moisture absorption and deformation, often causes distortion.
In addition, the oscillating plate that also metal material and synthetic material manufacture.But the density of metal material is high, uses metal material
The oscillating plate quality weight of material manufacture, and the oscillating plate that quality is overweight, can be impacted to tonequality.And the vibration of composite manufacture
Plate, its resistance to elevated temperatures is poor, and heat caused by speaker operation can impact to oscillating plate, makes its softening transform, equally
Tonequality can be impacted.
Therefore, need badly and a kind of oscillating plate and its manufacture method are provided, to solve the deficiencies in the prior art.
The content of the invention
Present invention aims at a kind of oscillating plate and its manufacture method provided for prior art deficiency.
In order to solve the above-mentioned technical problem, the technical solution adopted by the present invention is as follows：
A kind of oscillating plate, including oscillating plate body, the oscillating plate body are 1-15kg/m by density3Plastics be made；
The surface of the oscillating plate body is provided with elastic material coating, and the thickness of the elastic material coating is 0.01-1mm.
More preferably, the plastics are eps foam plastics.
More preferably, the elastic material coating preferably thickness range is 0.05-0.5mm.
More preferably, the thickness of the oscillating plate body is 1-10mm.
More preferably, the elastic material coating is polyurea elastic paint coating.
More preferably, the polyurea elastic paint is LINE-X polyurea elastic paints.
More preferably, the manufacture method of the oscillating plate, comprises the following steps：
1) absolute ethyl alcohol is used by the oscillating plate body wiped clean；
2) treat that the oscillating plate body after step 1) is dried, then polyurea elastic paint is added in flush coater and added
Heat is forced into 16~18Mpa to 55-60 DEG C, is then sprayed on the surface of the oscillating plate body；
3) the oscillating plate body after step 2) is placed on 20-25 DEG C of temperature, relative humidity 30-50% environment
Under dry in the shade 10-20min, the oscillating plate is made.
Beneficial effects of the present invention are：The oscillating plate, its oscillating plate body are made up of light plastic, oscillating plate body it is close
Spend for 1-15kg/m3, the density of oscillating plate body is low, light weight, and the surface of oscillating plate body is provided with elastic material coating,
Elastic material coating makes the intensity of oscillating plate body and resistance to elevated temperatures get a promotion, and the oscillating plate is applied into loudspeaker,
The tonequality of loudspeaker is set to get a promotion.
Brief description of the drawings
Fig. 1 is a kind of oscillating plate of the present invention and its sectional view of manufacture method.
Embodiment
With reference to embodiment, the present invention is further illustrated, and this is presently preferred embodiments of the present invention.
As shown in figure 1, a kind of oscillating plate, including oscillating plate body 1, the oscillating plate body 1 are 1-15kg/m by density3
Plastics be made；The surface of the oscillating plate body 1 is provided with elastic material coating 2, and the thickness of the elastic material coating 2 is
0.01-1mm.Oscillating plate body 1 is 1-15kg/m by density3Plastics be made, there is the advantages of density is low, light weight, still,
The universal non-refractory of light plastic, elastic material coating 2 is provided with by the surface of oscillating plate body 1, elastic material coating 2 makes
The intensity and resistance to elevated temperatures of oscillating plate body 1 get a promotion.The oscillating plate is applied into loudspeaker, due to the oscillating plate
Light weight, the tonequality of loudspeaker is set to get a promotion.
More preferably, the plastics are eps foam plastics.
More preferably, the elastic material coating 2 preferably thickness range is 0.05-0.5mm.
More preferably, the thickness of the oscillating plate body 1 is 1-10mm.
More preferably, the elastic material coating 2 is polyurea elastic paint coating.Polyurea elastic paint employs Amino End Group and gathered
This high technical principle of reactivity of ether and liquid diamine chain extenders as active hydrogen component and isocyanate component, nothing
Need catalyst, you can moment completes reaction even below zero degrees celsius in room temperature, and material property is splendid.
More preferably, the polyurea elastic paint is LINE-X polyurea elastic paints.LINE-X is a spraying protective coating
Company.LINE-X polyurea elastic paints, which are that one kind is quick, to be dried, multipurpose coating series.It shows fabulous adhesive surface,
It can vertically be sprayed, will not flowed downward using its fast curing times；And there is no residual solvent, it is pollution-free.
More preferably, the manufacture method of the oscillating plate, comprises the following steps：
1) absolute ethyl alcohol is used by the wiped clean of oscillating plate body 1；
2) treat that the oscillating plate body 1 after step 1) is dried, then polyurea elastic paint is added in flush coater
55-60 DEG C is heated to, and is forced into 16~18Mpa, is then sprayed on the surface of the oscillating plate body 1；
Because oscillating plate body 1 is easily influenceed by high temperature and deform, therefore, the optimal spraying temperature of polyurea elastic paint is
55-60℃。
3) the oscillating plate body 1 after step 2) is placed on 20-25 DEG C of temperature, relative humidity 30-50% ring
Dry in the shade 10-20min under border, and the oscillating plate is made.
Beneficial effects of the present invention are：The oscillating plate, its oscillating plate body are made up of light plastic, oscillating plate body it is close
Spend for 5-15kg/m3, the density of oscillating plate body is low, light weight, and the surface of oscillating plate body is provided with elastic material coating,
Elastic material coating makes the intensity of oscillating plate body and resistance to elevated temperatures get a promotion, and the oscillating plate is applied into loudspeaker,
The tonequality of loudspeaker is set to get a promotion.
The present invention is not limited to above-mentioned embodiment, all to realize the present invention using structure similar with the present invention and its method
All modes of purpose, within protection scope of the present invention.
