To be directly to another element or may be simultaneously present centering elements.
Only it is relative concept each other it should also be noted that, the orientation term such as left and right, upper and lower in the embodiment of the present invention
Or using the normal operating condition of product as reference, and should not be regarded as restrictive.
As depicted in figs. 1 and 2, a kind of diaphragm 1 provided in an embodiment of the present invention, including at least two layers of heat discoloration layer 10,
Each heat discoloration layer 10 can be faced with setting stacked on top of one another, the heat discoloration of at least two layers adjacent heat discoloration layer 10
Boundary's temperature value is different, and so, during temperature difference, each heat discoloration layer 10 can correspondingly change color state, each heat discoloration
Layer 10 by a certain color change to another color or can change to transparent, or, each heat discoloration layer 10 can be by transparent change extremely
A certain color, to increase the diversity of product shell outward appearance, easy to use and cost is low, and the thickness and product of product shell
Appearance and size it is unaffected, beneficial to ensure product develop to the direction lightly changed.Diaphragm 1 is applied to mobile phone, tablet personal computer etc.
, can be to embody outside product shell during different temperatures changes without using cell-phone cover during mobile terminal product scope
The diversity of sight, easy to use and cost is low, and can keep the light and thin degree of mobile terminal product.It is additionally, since mobile phone, puts down
The products such as plate computer are generated heat in use, and its case temperature will be also gradually increasing, by above-mentioned diaphragm 1, in different temperature
The color or transparency of the heat discoloration layer 10 of the lower different layers of degree are different, while mobile phone is beautified, user can be made to pass through film
The color that piece 1 is currently shown judges the state of temperature of mobile phone, and user can timely, intuitively experience the production such as mobile phone, tablet personal computer
The change of product, if temperature is too high, user can decline product temperature by stopping using or reducing the modes such as load, beneficial to guarantor
Shield product will not damage because of high temperature, effectively extend the service life of product, product is attractive in appearance and of good reliability.
Specifically, as depicted in figs. 1 and 2, from up to down, the heat discoloration critical value of each heat discoloration layer 10 can be with
Increase successively or reduce, so that display makes the color change of each heat discoloration layer 10 successively at different temperature.
In concrete application, as depicted in figs. 1 and 2, the change of the transparency or color of heat discoloration layer 10 can be gradual change
, i.e., edge up in temperature or gradually drop, the color of heat discoloration layer 10 from shallow to deep transition or from having color to transparent transition, until
The color change of heat discoloration layer 10 is to most deep or transparent, and as temperature gradually drops or edged up, the color of heat discoloration layer 10 also may be used
The color or state being gradually brought to before discoloration.Or the change of heat discoloration layer 10 can also be paroxysmal, that is, work as temperature
After reaching critical value, heat discoloration layer 10 changes color immediately.Heat discoloration layer 10 do not change colour before color can be it is transparent or
Other suitable colors, such as blueness, red etc.., can also be by the way that at different temperatures, same layer temperature-sensitive becomes in concrete application
Different colors is presented in chromatograph 10.Heat discoloration layer 10 is provided with multilayer, under different temperatures, by temperature from low to high, from table
Layer is to nexine, and each layer heat discoloration layer 10 is transparent successively, so as to show the true qualities of next layer of heat discoloration layer 10.I.e. on to
Under, the heat discoloration critical value of each heat discoloration layer 10 increases or reduced successively.
