In other words, same piezoelectric element 30 or multiple piezoelectric elements 30 for cooperateing with triggering identical function service can lead to The difference of the pressure of user's touch control operation is crossed to trigger different function services.Specifically, for example, a piezoelectric element 30 can be real Existing machine open/close and the function services of application program switching, then it is pre- at first to fall as user in the case where mobile phone is in open state If the first pressure in pressure limit can trigger the function services of application program switching when pressing above-mentioned piezoelectric element 30, at this time The window of application program switching can be shown on display screen 200；When user is pressed with falling second in second pre-set pressure range Power can trigger the function services of shutdown when pressing above-mentioned piezoelectric element 30.Wherein, first pressure is less than second pressure and first Pressure is more than preset pressure value, and the maximum pressure value of the first pre-set pressure range is less than the minimum pressure of the second pre-set pressure range It is worth and the minimum pressure values of the first pre-set pressure range is more than preset pressure value.For another example two piezoelectric elements 30 can be at the same time The function services returned with application program switching are realized in the state of being pressed, then is in open state in mobile phone and mobile phone is not located When under main interface, when user presses above-mentioned two piezoelectricity member at the same time to fall the first pressure in first pre-set pressure range It can trigger the function services of application program switching during part 30, can show the window of application program switching on display screen 200 at this time； When user presses two above-mentioned piezoelectric elements 30 at the same time to fall the second pressure in second pre-set pressure range, you can Trigger the function services returned.

In this way, piezoelectric element 30 can trigger different function services according to the difference of pressing dynamics, piezoelectric element 30 is answered With the manufacture cost for reducing housing unit 100 and electronic device 1000.
