Abstract
A composite vibration film comprises a base material. The surface of the base material is coated with a micro-nano ceramic layer. The micro-nano ceramic layer is a structural material enabling the rigidity and the tenacity to be greatly increased at the high temperature so that the prepared composite vibration film can have the advantages of being high in rigidity and tenacity, good in malleability and the like, the composite vibration film can allow great elastic deformation at the room temperature, and the purpose of high-definition tone quality can be achieved.
Description
Technical field
the present invention relates to loud speaker field, particularly a kind of composite type 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.
but under the prerequisite of same size and profile, vibrating diaphragm must have enough Hardness and toughness just can bear violent motion repeatedly, to avoid producing the situation that inelastic deformation is even broken, in order to address the above problem, current traditional method is that engineering ceramics is laid in to the surface of vibrating diaphragm and forms so-called ceramic vibrating diaphragm, to improve the mechanical characteristic of vibrating diaphragm itself, but the high fragility of engineering ceramics can cause restriction to a certain degree to the ductility of vibrating diaphragm on the contrary, so will certainly affect the energy spread of vibrating diaphragm and the tonequality of high definition cannot be provided.
Summary of the invention
the object of this invention is to provide a kind of tool high rigidity and high tenacity and at room temperature there is the composite type diaphragm of splendid ductility.
for achieving the above object, the technical solution used in the present invention is: a kind of composite type diaphragm, it comprises base material, is arranged on the micro-nano ceramic layer of at least one deck of described substrate surface, and described micro-nano ceramic layer is made by having at least unidimensional scale to be less than the ceramic material of 500 microns.
preferably, described base material has central part and edge part, and it is outer peripheral edges that described edge part is located at described central part, and described micro-nano ceramic layer is located at the upper surface of described central part.
preferably, described base material has central part and edge part, and it is outer peripheral edges that described edge part is located at described central part, and described micro-nano ceramic layer is located at the upper surface of described edge part.
preferably, described base material has central part and edge part, and it is outer peripheral edges that described edge part is located at described central part, and described micro-nano ceramic layer is located at the upper surface of described central part and the upper surface of described edge part.
preferably, described base material has central part and edge part, and it is outer peripheral edges that described edge part is located at described central part, and the number of described micro-nano ceramic layer is two-layer and is located at described central part is upper and lower surface.
further preferably, the section configuration of the section configuration of the central part of described base material and the edge part of described base material is all arc.
further preferably, described micro-nano ceramic layer be selected from aluminium oxide, silicon dioxide, zirconia, titanium dioxide, calcium phosphate, aluminium hydroxide, zinc oxide or carborundum and composition made.
further preferably, described micro-nano ceramic layer be preshaped after again with coating and transfer printing processing procedure, or paste and fuse processing procedure and combine with described base material.
further preferably, described micro-nano ceramic layer is to utilize physical vaporous deposition or chemical vapour deposition technique to be directly formed at described base material.
because technique scheme is used, the present invention compared with prior art has following advantages:
because composite type diaphragm of the present invention includes base material and micro-nano ceramic layer, micro-nano ceramic layer refers to a kind of in zero dimension, one dimension, two dimension or three-dimensional (corresponding to a little, line, face, three-dimensional) to have at least in yardstick unidimensional scale to be less than the ceramic material of micro-nano crystalline form of 500 microns made, this micro-nano ceramic layer is located at the surface of this base material, because this micro-nano ceramic layer is a kind of structural material that can at high temperature allow hardness and toughness be greatly improved, therefore, the present invention can have the advantage of high rigidity and high tenacity concurrently, at room temperature can produce good ductility simultaneously, make at room temperature can allow to realize compared with large strain the object of high definition tonequality.

in above accompanying drawing: 10, composite type diaphragm; 20, base material; 21, central part; 22, edge part; 30, micro-nano ceramic layer.
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 type diaphragm 10 includes base material 20 and micro-nano ceramic layer 30.
the material that base material 20 uses can be selected from one of them of metal, macromolecular material, cloth, silk, fiber crops, paper or composite material, is not limited especially at this.In the present embodiment, base material 20 has central part 21 and edge part 22, and edge part 22 is located at the outer peripheral edges of central part 21, and the section configuration of the section configuration of central part 21 and edge part 22 is all arc.
micro-nano ceramic layer 30 is defined herein as that a kind of in zero dimension, one dimension, two dimension or three-dimensional (corresponding to point, line, surface, solid) yardstick, to have at least unidimensional scale to be less than the ceramic material of micro-nano crystalline form of 500 microns made, and the micro-nano following nano-scale (1nm ~ 500um) that comprises of micron that means of indication herein, common material is oxide, nitride or carbide, such as aluminium oxide, silicon dioxide, zirconia, titanium dioxide, calcium phosphate, aluminium hydroxide, zinc oxide and carborundum etc.With base material 20 in conjunction with time, micro-nano ceramic layer 30 can be preshaped after again with coating and transfer printing processing procedure or paste and fuse processing procedure and be located at the upper surface of the central part 21 of base material 20, or also can utilize physical vaporous deposition or chemical vapour deposition technique micro-nano ceramic layer 30 to be directly formed to the upper surface of the central part 21 of base material 20.
embodiment bis-: shown in accompanying drawing 2, the present embodiment and embodiment mono-are basic identical, difference is that the number of micro-nano ceramic layer 30 is two-layer and is located at the upper and lower surface of central part 21.
