Abstract
The invention provides a diaphragm, which is provided with a spherical top part. The spherical top part is provided with a surface layer and a substrate layer connected with the surface layer, wherein the substrate layer is provided with a first substrate layer and a second substrate layer superposed with the first substrate layer; and the first substrate layer and the second substrate layer are made of different materials. The diaphragm effectively improves the ductility at high frequency.
Description
[technical field]
The present invention relates to a kind of vibrating diaphragm, particularly a kind of vibrating diaphragm that is used for electro-acoustic element.
[background technology]
Along with improving constantly of the market demand, electronic device such as mobile phone etc. develops to the slimming direction gradually, and requires its sound quality to become better and better, and this just requires the acoustical device in the mobile phone to develop towards direction miniature, slim, high tone quality.Vibrating diaphragm is the core component of acoustical device such as loud speaker, and the requirement of its acoustical behavior is also just improved thereupon.
The vibrating diaphragm of correlation technique is provided with the ball top.The ball top is provided with top layer and the substrate layer that links to each other with described top layer.Yet in the vibrating diaphragm of correlation technique, its substrate layer is the individual layer made from same material, and this structure makes the ductility of vibrating diaphragm in high frequency be restricted.
Therefore, be necessary to provide a kind of new vibrating diaphragm to overcome above-mentioned shortcoming.
[summary of the invention]
The technical problem that the present invention need solve provides a kind of high frequency ductility can better vibrating diaphragm.
According to above-mentioned technical problem, the present invention has designed a kind of vibrating diaphragm, its objective is such realization: a kind of vibrating diaphragm, it is provided with the ball top, described ball top is provided with top layer and the substrate layer that links to each other with described top layer, wherein, described substrate layer be provided with first substrate layer and with the second superimposed substrate layer of first substrate layer, described first substrate layer is different with the described second substrate layer material therefor.
Preferably, described first substrate layer is to be become by wooden leather, and described second substrate layer is to be made by expanded polyester.
Preferably, described expanded polyester is selected the PETG foaming body.
Preferably, described top layer is made by aluminium foil.
Preferably, described top layer is connected by being equipped with glue with described first substrate layer.
Preferably, described first substrate layer is connected by being equipped with glue with described second substrate layer.
Compare with correlation technique, the included substrate layer of vibrating diaphragm provided by the invention uses different materials to make.Different material ductility differences can same sex complementation, makes the vibrating diaphragm of correlation technique that better ductility be arranged in high frequency.
[description of drawings]
Fig. 1 is the vertical view of vibrating diaphragm provided by the invention.
Fig. 2 is the ball top cut-away view of vibrating diaphragm provided by the invention.
Fig. 3 is the enlarged drawing of A part shown in Figure 2.
[embodiment]
The invention will be further described below in conjunction with drawings and embodiments.
As Fig. 1, Fig. 2 and shown in Figure 3, a kind of vibrating diaphragm 1 provided by the invention, it is provided with ball top 11.Ball top 11 is provided with top layer 111 and the substrate layer 12 that links to each other with top layer 111.Wherein, substrate layer 12 is provided with first substrate layer 121 and different with second substrate layer, 122 material therefors with superimposed second substrate layer, 122, the first substrate layers 121 of first substrate layer 121.
Because first substrate layer 121 is different with the material of second substrate layer, 122 usefulness, and its ductility difference of different materials forms same sex complementation, so just makes the vibrating diaphragm 1 of correlation technique that better ductility is arranged in high frequency.
In addition, ball top 11 can be all shapes that can realize, as circular, runway shape, and square and polygon etc.
Above-described only is embodiments of the present invention, should be pointed out that for the person of ordinary skill of the art at this, under the prerequisite that does not break away from the invention design, can also make improvement, but these all belongs to protection scope of the present invention.
