As shown in Figure 3, Figure 4, when user's finger is pressed against in screen main body 320, shape can occur for the screen main body 320
Become so that the seal cavity 310 where high sensitivity microphone deforms upon, and then causes the cavity body of the seal cavity 310
Product reduces, air pressure increase in cavity, now, because high sensitivity microphone is located in the seal cavity 310, high sensitivity Mike
Wind detects the size of cavity internal pressure change in the following manner：Vibration membrane in its sound pick-up can be in the seal cavity 310
Cavity air pressure increase in the case of deform upon so that the capacitance of high sensitivity microphone changes, faint to produce
Electric signal, and because screen main body 320 dubbed, flicking, again different by the deformation of rear generation so that the annular seal space
The degree that the cavity volume of body 310 reduces also differs, i.e. the degree of cavity air pressure increase is also different, finally causes the Gao Ling
The size of ultra-weak electronic signal is also different caused by sensitivity microphone, when amplifying circuit amplifies caused by the high sensitivity microphone
After ultra-weak electronic signal enhanced processing, just it is converted into corresponding touch-control electric signal and obtains corresponding pressure value, the pressure can be realized
The pressure touch of power touch screen 300.

Body 420 is fastened on terminal center 440 by sealing foam 450 and glue (not shown) so that terminal center 440 and screen master
The seal cavity 410 is formed between the inner side of body 420.The sealing foam can use PU foams, either use CR foams or adopt
With EPE foams, to ensure the sealing property of the seal cavity 410 by the good foam structure of sealing.
Screen main body 420 is mainly used in receiving pressed by external force, and is deformed upon under the pressed by external force so that the annular seal space
The air pressure of body 410 changes.Specifically, the screen main body 420 includes elastic touch layer and display layer, and the elastic touch layer is used
In receiving the pressed by external force, to be deformed upon under the pressed by external force.And the display layer is then shown for carrying out image.
Signal acquisition process element 430 is built in the seal cavity 410, as shown in figure 8, the signal acquisition process element
430 are mainly located at the centre position of the seal cavity 410, that is, corresponding with the centre position of the screen main body 420.Its is main
Effect is for being touch-control electric signal by the air pressure change signal acquisition process of the seal cavity 410.Specifically, the signal acquisition
Treatment element 410 includes signal collecting element and signal enhanced processing element, wherein, the signal collecting element concretely pressure
Sensor, it can produce ultra-weak electronic signal under the air pressure change of the seal cavity 410.The signal enhanced processing element specifically may be used
For an amplifying circuit, for being touch-control electric signal by ultra-weak electronic signal enhanced processing caused by the pressure sensor.
