Under (include first peak value P1) section.In other embodiments, all touch-control hop counts can also be designed in first peak
The sections of value P1 (including first peak value P1) below.
In summary, no matter the quantity of the electric potential contact of button why, with the deformation stroke of the electroconductive elastic sheet of button
Increase, electroconductive elastic sheet sequentially contact more and more electric potential contacts from outside to inside, i.e. the deformation stroke of electroconductive elastic sheet is longer, connects
The more, button can provide touch-control hop count the more to tactile electric potential contact quantity.The current potential of the electric potential contact contacted with electroconductive elastic sheet
It can change, controller perceives the potential change of this little electric potential contact, exports according to this to the pressing signal that should change or execution
Corresponding function.
In addition, the quantity of different electric potential contacts, the deformation stroke of electroconductive elastic sheet and the relation curve of pressing force may not
Together, this can be realized by designing the physical dimension of electroconductive elastic sheet.
For example, as shown in Figure 12 A and Figure 12 B, Figure 12 A illustrate bowing for the electroconductive elastic sheet 621 according to one embodiment of the invention

Pressure, therefore enter step S150；If it is not, then controller 140 can determine whether the first ring-type electric potential contact 123 has returned to former electricity
Position；If so, then wait the pressing again of user；If it is not, then rest on step S140.
In step S150, controller 140 responds the second pressing force F2 pressing, the second function is performed, wherein the second work(
Can be identical with the first function phase XOR, and the second function can be any function of electronic installation.
To sum up, the Trackpad of the embodiment of the present invention additionally provides vertical in addition to providing the two-dimentional touch-control dimension of touch surface
The vertical touch-control dimension of touch surface, Trackpad is set to turn into three-dimensional touch plate.In one embodiment, different pressing forces makes Trackpad
The electroconductive elastic sheet of button produce different deformation stroke, and the current potential of the electric potential contact of varying number is produced change, touch-control
The controller of plate sends corresponding touching signals to other circuit elements according to the potential change of this little electric potential contact, or directly holds
Function corresponding to row, e.g. perform any function for the electronic installation for being equipped with Trackpad.In a word, the embodiment of the present invention
Trackpad provides several touch-control sections along vertical touch-control dimension.
In summary, although the present invention is disclosed above with preferred embodiment, so it is not intended to limit the present invention.This hair
Those of ordinary skill in bright art, without departing from the spirit and scope of the present invention, when various changes can be made
With retouching.Therefore, the scope of protection of the present invention is defined by those of the claims.
