Abstract
The utility model provides a composite vibrating diaphragm. The composite vibrating diaphragm comprises a substrate layer which has a first surface and a second surface opposite to the first surface. The composite vibrating diaphragm further comprises a polyether-ether-ketone thin film attached and covered on the first surface and a thermoplastic polyurethane elastomer attached and covered on the second surface. The composite vibrating diaphragm provided by the utility model can effectively improve the defect of distortion of a loudspeaker, and the vibrating intensity of the composite vibrating diaphragm is increased. Moreover, the composite vibrating diaphragm is low in production cost and simple in manufacture procedure.
Description
[technical field]
The utility model relates to loud speaker field, relates in particular to a kind of composite diaphragm for loud speaker field.
[background technology]
Along with improving constantly of the market demand, electronic device is if mobile phone etc. is gradually to slimming future development, and requires its sound quality to become better and better, and this just requires acoustical device in mobile phone towards miniature, slim, high tone quality future development.Vibrational system is the core component of the acoustical devices such as loud speaker, therefore, along with the development of acoustical device, the requirement of its acoustical behavior is also just improved thereupon.
Vibrating diaphragm in correlation technique is to form by single cloth film or the compacting of other hot pressing moulding material.Yet the vibrating diaphragm of this structure because rigidity is inadequate, easily produces diaphagras when high frequency, causes distortion, thereby affects sense of hearing.In addition, in actual applications, when not affecting tonequality, be to improve the film strength of shaking, conventional way is for increasing the thickness of regional area on vibrating diaphragm in the industry,, it is identical that the vibrating diaphragm that homogenous material is made is pressed into rear vibrating diaphragm thickness everywhere, can not meet above-mentioned requirement.
Therefore, be necessary to provide a kind of novel composite diaphragm to overcome above-mentioned shortcoming.
[utility model content]
The composite diaphragm that provides a kind of acoustical behavior good is provided the purpose of this utility model.
The technical solution of the utility model is as follows: a kind of composite diaphragm, comprise substrate layer, described substrate layer has first surface and the second surface relative with described first surface, and this composite diaphragm also comprises the poly (ether ether ketone) film pasting on described first surface and pastes the TPUE on described second surface.
Preferably, this composite diaphragm also comprises the glue layer being separately positioned on described first surface and second surface, and described poly (ether ether ketone) film and described TPUE paste on described first surface and second surface by described glue layer respectively.
Preferably, described substrate layer is polyester film material.
Preferably, described substrate layer is benzene dicarboxylic acid butanediol ester.
The beneficial effects of the utility model are: the composite diaphragm that the utility model provides can effectively improve the defect of loudspeaker distortions, have improved the oscillation intensity of composite diaphragm, and production cost is low, production process is simple.
[accompanying drawing explanation]
Fig. 1 is the structural representation of the utility model composite diaphragm the first embodiment;
Fig. 2 is the structural representation of the utility model composite diaphragm the second embodiment.
[embodiment]
Below in conjunction with drawings and embodiments, the utility model is described in further detail.
As shown in Figure 1, in the first embodiment of the present utility model, this composite diaphragm 100 comprises substrate layer 101, and this substrate layer 101 has first surface 104 and the second surface 105 relative with first surface 104.This substrate layer 101 can be selected polyester film material, and for example benzene dicarboxylic acid butanediol ester (polybutylene terephthalate is called for short PBT), also can select other suitable materials.
This composite diaphragm 100 also comprises the poly (ether ether ketone) film 102(Polyether Ether Ketone pasting on first surface 104, be called for short PEEK) and paste the TPUE 103(Thermoplastic polyurethanes on described second surface 105, be called for short TPU).Poly (ether ether ketone) film 102 and TPUE 103 all have good toughness and rigidity, therefore make the intensity of this composite diaphragm higher, good stability to the variation of environment, can effectively reduce the resonance frequency of product, widen frequency band, improve the resistance to power capability of loud speaker, and technique is simple, production cost is low.
As shown in Figure 2, in the second embodiment of the present utility model, this composite diaphragm 100 is on the basis of above-mentioned the first embodiment, also comprise the first surface and the glue layer on second surface 106 that are arranged on substrate layer 101, poly (ether ether ketone) film 102 and TPUE 103 paste respectively on the first surface and second surface of substrate layer 101 by this glue layer 106.Therefore, the composite diaphragm in the second embodiment is the structure of a kind of five layers, and the structure of this five layers makes composite diaphragm have better mechanical performance, also can improve to a certain extent the acoustical behavior of composite diaphragm simultaneously.
Above-described is only execution mode of the present utility model; at this, it should be pointed out that for the person of ordinary skill of the art, do not departing under the prerequisite of the utility model creation design; can also make improvement, but these all belong to protection range of the present utility model.
Claims (4)
1. a composite diaphragm, it comprises substrate layer, described substrate layer has first surface and the second surface relative with described first surface, it is characterized in that, this composite diaphragm also comprises the poly (ether ether ketone) film pasting on described first surface and pastes the TPUE on described second surface.
2. composite diaphragm according to claim 1, it is characterized in that, this composite diaphragm also comprises the glue layer being separately positioned on described first surface and second surface, and described poly (ether ether ketone) film and described TPUE paste on described first surface and second surface by described glue layer respectively.
