Between circuit element other than target object fingerprint film, should also include the true finger.
Relatively, for the first above-mentioned situation, finger directly contacts first conduct piece 241 and described second surely
When conduct piece 243, the circuit element between first conduct piece 241 and second conduct piece 243 is connected in series in as institute
State true finger.
For the third above-mentioned situation, first conduction is directly placed at when fingerprint film not to be attached on true finger
When on part 241 and second conduct piece 243, be connected in series in first conduct piece 241 and second conduct piece 243 it
Between circuit element be the fingerprint film.
Correspondingly, when first detection circuit 251 provides the first driving signal to first conduct piece 241, institute
The first conduct piece 241 is stated by the first driving signal received by contacting first conduct piece 241 and second conduction
The target object (the case where for true finger plaster fingerprint film, first driving signal also pass through true finger) of part 243 is transferred to
Second conduct piece 243, corresponding first sensing signal that exports of second conduct piece 243 is to first detection circuit 251.
Since the electrical property feature of true finger, true finger combination fingerprint film, fingerprint film is different, correspondingly, when first drive
Dynamic signal pass through true finger, true finger and fingerprint film, fingerprint film respectively after, second conduct piece respectively corresponds and receives
Signal (that is, first sensing signal) is different, thus, first detection circuit 251 is true according to first sensing signal
Whether the target object for contacting first conduct piece 241 and the second conduct piece 243 surely is genuine human body.

In other change embodiments, the through-hole is for example arranged in the rear shell 30, first conduct piece 241
It exposes to the open air with the second conduct piece 243 in the through hole, the corresponding via regions setting of the sensor 25.Described first is conductive
Part 241 and the second conduct piece 243 are compared to the sensor 25 closer to the outer surface of the rear shell 30.
It is corresponded on the side wall of electronic equipment 100 alternatively, the shell is arranged in the through-hole, the corresponding institute of the sensor 25
State via regions setting.
Further, the electronic equipment of the prior art is usually in the one button group with fingerprint recognition mould group of front setting
Part lacks entity touch key-press, causes user poor to the usage experience of electronic equipment.
In order to solve this technical problem, the application proposes: being made using first conduct piece 241 and the second conduct piece 243
For touch key-press.First detection circuit 251 is for driving first conduct piece 241 and second conduct piece 243 to hold
Row touch-sensing.
Since the application is made in the case where not increasing touch electrode using the first conduct piece 241 and the second conduct piece 243
For touch key-press, thus, the user experience of electronic equipment 100 can be improved.
First conduct piece 241 can such as be used separately as similar and different first of function with second conduct piece 243
Touch key-press and the second touch key-press.First touch key-press is in Menu key, navigation key, volume control key, return key etc.
Any one or a few, second touch key-press is any in return key, navigation key, volume control key, return key etc.
It is one or more of.For example, second touch key-press is then Menu key when first touch key-press is return key；Work as institute
When first touch key-press is that volume increases key, second touch key-press is then volume down key；When first touch key-press
For to the left or scroll up key when, second touch key-press is corresponding then to the right or to scroll down through key；When first touch
When key is Page Up, when second touch key-press is then Page Down.The application only illustratively lists herein
The touch key-press of first conduct piece 241 and the second conduct piece 243 as some functions, so, the application is not limited thereto, described
First conduct piece 241 can also be the touch key-press of other functions with second conduct piece 243, for example, when taking pictures or imaging,
First conduct piece 241 can also be respectively as enlargement key (Zoom In) and diminution key (Zoom with second conduct piece 243
Out) etc..First conduct piece 241 and touch key-press of second conduct piece 243 as which kind of function, manufacturer or user
It can flexibly be set as needed.
According to preset function, when first conduct piece 241 and the second conduct piece 243 are used as touch key-press and are touched
When touching, the corresponding controlling electronic devices 100 of the processor 40 executes corresponding function.
Citing, when browsing webpage, user can accordingly control webpage and carry out upwards by touching the first conduct piece 241
It rolls.
So, when sensor 25 executes biological information sensing to genuine human body, first detection circuit 251 is provided
The ground signalling gives first conduct piece 241 and the second conduct piece 243.
In addition, when the bio-identification mould group 21 is triggered and executes biological information sensing, the first detection electricity
Road 251 can also first drive first conduct piece 241 and the second conduct piece 243 to execute touch-sensing.After detecting touch, then
First conduct piece 241 and the second conduct piece 243 is driven to execute true and false human body sensing.First conduct piece is contacted when determining
241 and second target object of conduct piece 243 when being genuine human body, the sensor 25 starts to execute biology to genuine human body special
Reference breath sensing.
For example, when user needs to be implemented biological information using wechat payment and senses, the corresponding touching of the processor 40
Bio-identification mould group 21 is sent out to work.Correspondingly, when first detection circuit 251 detect first conduct piece 241 or/and
When second conduct piece 243 is touched by target object, first detection circuit 251 then detects contact first conduct piece
241 and second the target object of conduct piece 243 whether be genuine human body；Relatively, when user carries out web page browsing without holding
When row biological information senses, first detection circuit 251 drives the first conduct piece 241 and the second conduct piece 243 to execute
Touch-sensing, at this point, first conduct piece 241 and the second conduct piece 243 are used separately as touch key-press, when the first detection circuit
After 251 detect the touch of target object, the processor 40 is then set according to the corresponding control electronics of preset touch key-press function
Standby 100 execute corresponding function, such as page turning.
Ground is changed, in other embodiments, one of first conduct piece 241 and the second conduct piece 243 can
As touch key-press, and it is feasible that another one, which is then not used as touch key-press all,.
As it can be seen that the bio-identification mould group 21 of the electronic equipment 100 of the application includes the first conduct piece 241 for mutually separating and the
Two conduct pieces 243, can not only realize the detection of true and false human body, also can be used as the touch key-press of similar and different function.Correspondingly,
