Embodiment
The invention will be further described with reference to the accompanying drawings and examples.
As Figure 1-4, the button is included by 1, capacitance sensing mechanism 2 and the processor of compressing switch（Non- label）.It is described
Capacitance sensing mechanism 2 positioned at it is described by compress switch 1 at least side or be placed in described by compressing switch on 2, the capacitance sensing
Mechanism 2 surrounded for annular it is described by compressing switch 1, when the capacitance sensing mechanism 2 positioned at it is described by compressing switch on 1 when, its whole
Or part cover it is described by compressing switch 1.It is described by compress switch 1 and the capacitance sensing mechanism 2 be respectively connecting to the processing
Device.
Lower mask body place of matchmakers states the structure of capacitance sensing mechanism.
As shown in figure 5, the capacitance sensing mechanism 2 includes substrate 20, first electrode 21 and cover plate 22, the first electrode
21 are arranged on substrate 20, and the cover plate 22 is covered in the first electrode 21, and the first electrode 21 is connected to the place
Manage device.
As shown in fig. 6, the capacitance sensing mechanism 2 includes substrate 20, first electrode 21, cover plate 22 and second electrode 23,
The first electrode 21 is arranged on substrate 20, the relatively described insulation set of first electrode 21 of the second electrode 23, and described
One electrode is connected to the processor.The first electrode 21 and the second electrode 23 include conductive layer and insulating layer, institute
State conductive layer to be layed on the substrate 20, the insulating barrier is layed on the conductive layer.
As Figure 7-8, in use, when the button is pressed, described 1 to be opened by compressing switch, transmission is opened
Signal is opened to the processor, simultaneously as human body touch button, the capacitance sensing mechanism 2 produces capacitance signal, and sends
Capacitance signal is to the processor.The processor judges that the button is effectively to press according to the signal of reception, or false touch.
When the processor receives the open signal and the capacitance signal simultaneously, then the processor judges described by pressing off
Close and open corresponding function, if the processor only detects the open signal or the capacitance signal, for nothing
Effect pressing, the processor judgement is described will not to open corresponding function by compressing switch.
More specifically, described 1 to be pressed by compressing switch as shown in fig. 7, when pressing the button, transmission open signal is extremely
The processor.Meanwhile if the button is pressed by human body, the capacitance sensing mechanism 2 senses capacitance signal, and will be upper
State capacitance signal and be sent to the processor.The processor receive it is described by compress switch 1 open signal and the electric capacity sense
The capacitance signal of mechanism 2 is surveyed, judges that the button operates for user and presses, open function corresponding to the button.If described press
Key presses for other objects, described to press signal to the processor, because other objects are non-human, institute by 1 transmission that compresses switch
Capacitance signal can not be sensed with the capacitance sensing mechanism 2, therefore, the processor can only receive by compress switch 1 letter
Number, the processor judges that this time pressing is false touch.
It is described by pressing off when pressing the button as shown in figure 8, button, which is described below, prevents another embodiment of false touch
Close and 1 opened, send open signal to the processor, the processor control the capacitance sensing mechanism 2 to detect whether for
Human body touch, and detection signal is sent to the letter passed back to the processor, the processor according to the capacitance sensing mechanism 2
Number, determine whether effectively to touch.
It is described 1 to be pressed by compressing switch specifically, user presses the button, it is described by the 1 transmission open signal that compresses switch
To the processor, the processor receives the open signal, sends detection signal to the capacitance sensing mechanism 2, described
Capacitance sensing mechanism 2 receives the detection signal, has detected whether human contact's button, i.e., whether is able to detect that electric capacity.If
The capacitance sensing mechanism 2 detects capacitance signal, sends capacitance signal to the processor, and the processor is according to receiving
Capacitance signal, judge that this time pressing effectively to touch, opens the corresponding function of button.If the capacitance sensing mechanism 2 fails
Capacitance signal is detected, the processor does not receive the capacitance signal of capacitance sensing mechanism, judges that this time pressing is false touch, is not opened
Open the corresponding function of button.
The processor can also be directed to the capacitance signal that the capacitance sensing mechanism 2 senses and further be sentenced
It is disconnected, a threshold value is first set, judges whether received capacitance signal is more than the threshold value of setting, if more than the threshold value set to have
Signal is imitated, if less than the threshold value of setting, for invalid signals.
Only when operator's pressing keys, the capacitance sensing mechanism 2 forms circuit loop by human body touch, institute
The electric capacity of the capacitance sensing mechanism 2 can be detected by stating processor, and when insulating bodies touches the button, the electric capacity
Sensing mechanism 2 can not form capacitor loop, and the processor can not detect the electric capacity of capacitance sensing mechanism 2, therefore, only when
When human body presses the button, the button just can the corresponding operating of basis make corresponding reaction, prevent because other objects squeeze
The button is pressed to produce false touch.
