Description
Technical field
The utility model is related to speaker technology field more particularly to a kind of oscillating plates.
Background technology
Oscillating plate is the important component of loud speaker.Traditional oscillating plate is made of paper pulp, this papery oscillating plate
Shortcoming is that specific modulus is small, and 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 impact sound quality.And the vibration of composite material manufacture
Plate, high temperature resistance is poor, and the heat that when speaker operation generates can impact oscillating plate, make its softening transform, equally
Sound quality can be impacted.
Therefore, it is urgent to provide a kind of oscillating plate, to solve the deficiencies in the prior art.
Utility model content
The utility model aim is, for a kind of oscillating plate that the prior art is insufficient and provides.
In order to solve the above-mentioned technical problem, the technical solution adopted in the utility model is as follows：
A kind of oscillating plate, including oscillating plate ontology, the oscillating plate ontology is 1-15kg/m by density3Plastics be made；
The surface of the oscillating plate ontology is equipped 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 ontology is 1-10mm.
More preferably, the elastic material coating is polyurea elastic paint coating.
The beneficial effects of the utility model are：The oscillating plate, oscillating plate ontology are made of light plastic, oscillating plate ontology
Density be 1-15kg/m3, the density of oscillating plate ontology is low, light weight, and the surface of oscillating plate ontology is equipped with elastic material
Coating, elastic material coating make the intensity of oscillating plate ontology and high temperature resistance get a promotion, which is applied to and is raised one's voice
In device, the sound quality of loud speaker is made to get a promotion.
Description of the drawings
Fig. 1 is a kind of sectional view of oscillating plate of the utility model.
Specific embodiment
The utility model is further described with reference to embodiment, this is the preferred embodiment of the utility model.
As shown in Figure 1, a kind of oscillating plate, including oscillating plate ontology 1, the oscillating plate ontology 1 is 1-15kg/m by density3
Plastics be made；The surface of the oscillating plate ontology 1 is equipped with elastic material coating 2, and the thickness of the elastic material coating 2 is
0.01-1mm.Oscillating plate ontology 1 is 1-15kg/m by density3Plastics be made, have the advantages that density is low, light weight, still,
The universal non-refractory of light plastic is equipped with elastic material coating 2 by the surface of oscillating plate ontology 1, and elastic material coating 2 makes
The intensity and high temperature resistance of oscillating plate ontology 1 get a promotion.The oscillating plate is applied in loud speaker, due to the oscillating plate
Light weight makes the sound quality of loud speaker 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 ontology 1 is 1-10mm.
More preferably, the elastic material coating 2 is polyurea elastic paint coating.Polyurea elastic paint employs Amino End Group and gathers
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, and material property is splendid below room temperature even zero degrees celsius.
The beneficial effects of the utility model are：The oscillating plate, oscillating plate ontology are made of light plastic, oscillating plate ontology
Density be 5-15kg/m3, the density of oscillating plate ontology is low, light weight, and the surface of oscillating plate ontology is equipped with elastic material
Coating, elastic material coating make the intensity of oscillating plate ontology and high temperature resistance get a promotion, which is applied to and is raised one's voice
In device, the sound quality of loud speaker is made to get a promotion.
The utility model is not limited to the above embodiment, it is all using structure similar with the utility model and its method come real
All modes of existing the utility model aim, are within the protection scope of the utility model.
