Abstract
The invention discloses a composite vibrating diaphragm, which comprises a substrate, wherein the surface of the substrate is provided with at least one graphdiyne layer. Because the substrate is provided with the graphdiyne layer and graphdiyne is a two-dimensional structural material with light weight and high rigidity, the prepared composite vibrating diaphragm has the characteristics of hardness, toughness, low density and the like, and practical aims of having durability, providing highly-clear tone quality and the like are fulfilled.
Description
Technical field
The present invention relates to loud speaker field, particularly a kind of composite diaphragm.
Background technology
Along with the universal and progress of Digital Media, digital music, constantly towards high-facsimile (Hi-Fi) development, also drives the research and development agitation of various professional loud speakers.In order to pursue more superior audio frequency output characteristic, the vibrating diaphragm of loud speaker is one of part of wherein most critical.
Under the prerequisite of same size, external form, vibrating diaphragm must have enough Hardness and toughness just can bear violent motion repeatedly, the problem of avoiding inelastic deformation even to break.Meanwhile, vibrating diaphragm also must have lower density so that motion trippingly, so just contributes to energy spread and the tonequality of high definition is provided.
Therefore, how providing a kind of hardness, toughness and low-density vibrating diaphragm of having concurrently, is that this area personage should consider in fact.
Summary of the invention
The object of this invention is to provide a kind of composite diaphragm with high rigidity, high tenacity, low weight.
For achieving the above object, the technical solution used in the present invention is: a kind of composite diaphragm, comprise base material, and it is characterized in that: described substrate surface is at least provided with one deck graphite alkene layer.
Preferably, described base material comprise centre central part, be positioned at the edge part of described central part surrounding.
Further preferably, described graphite alkene layer is arranged on described central part upper surface.
Further preferably, described graphite alkene layer is arranged on described central part upper surface and lower surface.
Further preferably, described graphite alkene layer is arranged on described edge part.
Preferably, described graphite alkene layer is physical vapour deposition (PVD), chemical vapour deposition (CVD), coating, transfer printing, pastes or fuse processing procedure a kind of mode wherein and arrange.
Preferably, the material of described base material is wherein a kind of of metal, macromolecular material, cloth, silk, fiber crops, paper and composite material.
Preferably, the section of described central part and edge part is arc.
Because technique scheme is used, the present invention compared with prior art has following advantages:
Because the present invention is provided with graphite alkene layer on base material, graphite alkene is the two-dimensional structure material that a kind of light weight and rigidity are high, therefore prepared composite diaphragm can have the characteristics such as hardness, toughness and low-density concurrently, realizes durable and the practicality objects such as high definition tonequality can be provided.
Accompanying drawing explanation
Accompanying drawing 1 is the schematic cross-section of embodiment mono-;
Accompanying drawing 2 is the schematic cross-section of embodiment bis-;
Accompanying drawing 3 is the schematic cross-section of embodiment tri-;
Accompanying drawing 4 is the schematic cross-section of embodiment tetra-.
In above accompanying drawing: 10, composite diaphragm; 20, base material; 21, central part; 22, edge part; 30, graphite alkene layer; 40, composite diaphragm; 50, base material; 51, central part; 60, graphite alkene layer; 70, composite diaphragm; 80, base material; 82, edge part; 90, graphite alkene layer; 100, composite diaphragm; 110, base material; 111, central part; 112, edge part; 120 graphite alkene layers.
Embodiment
Below in conjunction with embodiment shown in the drawings, the invention will be further described:
Embodiment mono-: shown in accompanying drawing 1, a kind of composite diaphragm 10 comprises base material 20 and graphite alkene layer 30.
This graphite alkene layer 30 is the upper surface of being located at base material 20 central parts 21, the material of graphite alkene layer 30 is graphite alkene, graphite alkyne series is simultaneously with sp, sp2, the formed monoatomic layer structure of tri-kinds of hybrid state of sp3, be that graphite alkene is the network-like full carbon molecular structure of a kind of two dimensional surface, carbon-to-carbon triple bond wherein (being sp hybrid state) is the important linkage unit forming in graphite alkene structure, because it can not be subject to the variable effect of cis-trans isomerism, therefore can keep linear state always; Wherein, described graphite alkene can have following formula one to formula four a kind of structural formula wherein:
Embodiment bis-: shown in accompanying drawing 2, composite diaphragm 40 comprises base material 50 and two-layer graphite alkene layer 60, and two-layer graphite alkene layer 60 is located at respectively upper surface and the lower surface of base material 50 central parts 51.
Embodiment tri-: shown in accompanying drawing 3, composite diaphragm 70 comprises base material 80 and graphite alkene layer 90, and graphite alkene layer 90 is located at the edge part 82 of base material 80.
Embodiment tetra-: shown in accompanying drawing 4, composite diaphragm 100 comprises base material 110 and graphite alkene layer 120, and graphite alkene layer 120 is covered in the upper surface of base material 110 central parts 111 and edge part 112 simultaneously.
Because graphite alkene is the two-dimensional structure material that a kind of light weight and rigidity are high, therefore based on aforementioned and other similar designs, the present invention's composite diaphragm can have the characteristics such as hardness, toughness and low-density concurrently, thereby realize, provides durable and the practicality objects such as high definition tonequality can be provided.
Above-described embodiment is only explanation technical conceive of the present invention and feature, and its object is to allow person skilled in the art can understand content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences that Spirit Essence is done according to the present invention change or modify, within all should being encompassed in protection scope of the present invention.
