Description of drawings
Fig. 1 is the circuit diagram of an embodiment of mobile phone of the present invention.
Embodiment
Consult Fig. 1, Fig. 1 is the circuit diagram of an embodiment of mobile phone of the present invention.Mobile phone of the present invention comprises: power management chip A1, baseband chip A2, two button KEY1, KEY2 and button detection module B.
Baseband chip A2 comprises control port SYSRST, two the first button detection port COL1, COL2 and one second button detection port ROW1.Power management chip A1 provides the control port SYSRST of first control signal to baseband chip A2 after the start key is pressed.Baseband chip A2 starts mobile phone when control port SYSRST receives first control signal.Power management chip A1 continues to provide first control signal behind handset starting.First end of button KEY1 connects the first corresponding button detection port COL1, and second end connects the second button detection port ROW1.First end of button KEY2 connects the first corresponding button detection port COL2, and second end connects the second button detection port ROW1.In the present embodiment, the first button detection port COL1, COL2 are the row detection port, and export the first button detection signal respectively, and the second button detection port ROW1 then is the row detection port, and exports the second button detection signal.Button detection module B provides second to control signal to baseband chip A2 when two button KEY1, KEY2 press simultaneously, and baseband chip A2 closes mobile phone when receiving second control signal.In the present embodiment, first control signal and the first button detection signal are high level signal, and second control signal and the second button detection signal are low level signal.
In the present embodiment, button detection module B comprises first resistance R 1, second resistance R 2, two the first switch element D1, D2 and second switch element Q1.First end of first resistance R 1 connects the first reference level VGND, and first end of second resistance R 2 connects the second reference level VDD.First end of the first switch element D1 is connected between button KEY1 and the corresponding first button detection port COL1, and second end connects second end of first resistance R 1.First end of the first switch element D2 is connected between button KEY2 and the corresponding first button detection port COL2, and second end connects second end of first resistance R 1.First end of second switch element Q1 is connected in control port SYSRST, second end of second switch element Q1 is connected between second end of second end of the first switch element D1, D2 and first resistance R 1, and the 3rd end of second switch element Q1 connects second end of second resistance R 2.
In the present embodiment, the first reference level VGND is a ground level, the second reference level VDD is a high level, the first switch element D1, D2 are diode, first end of the first switch element D1, D2 is the positive pole of diode, second end of the first switch element D1, D2 is the negative pole of diode, second switch element Q1 is a N type metal-oxide-semiconductor, first end of second switch element Q1 is the drain electrode of N type metal-oxide-semiconductor, second end of second switch element Q1 is the source electrode of N type metal-oxide-semiconductor, and the 3rd end of second switch element Q1 is the grid of N type metal-oxide-semiconductor.In a preferred embodiment, the resistance of first resistance R 1 is preferably 100000 ohm, and the resistance of second resistance is preferably less than 1000 ohm.
As button KEY1, when KEY2 does not press, the first switch element D1, D2 conducting under the effect of first button detection signal (being high level signal) and first reference level (being ground level), as button KEY1, when KEY2 is pressed, the first button detection port COL1, COL2 and the second button detection port ROW1 short circuit, the signal at the first button detection port COL1, COL2 place becomes low level signal by high level signal, and the first switch element D1, D2 end under the effect of second button detection signal (being low level signal) and first reference level (being ground level).That is to say that above-mentioned connected mode makes the first switch element D1, D2 in corresponding key KEY1, conducting when KEY2 does not press, and at corresponding key KEY1, end when KEY2 presses.
Therefore, when among button KEY1, the KEY2 any one do not pressed, first switch element D1, the D2 conducting corresponding with the button KEY1, the KEY2 that do not press made second end of second switch element Q1 be in high level.At this moment, because the 3rd end of second switch element Q1 and the voltage difference between second end cause first end of second switch element Q1 and second end to end less than conduction threshold.
When button KEY1, KEY2 press simultaneously, the first switch element D1, D2 end, second end of second switch element Q1 is in ground level, at this moment, because the 3rd end of second switch element Q1 and the voltage difference between second end cause first end and the second end conducting of second switch element Q1, and then the control port SYSRST of baseband chip A2 are connected to ground level greater than conduction threshold, promptly provide second control signal to control port SYSRST, baseband chip A2 closes mobile phone.
In other embodiments, the quantity of button can be more than two, and the first button detection port in the baseband chip, the quantity of first switch element keep identical with the quantity of button.And the second button detection port in the baseband chip also can be a plurality of, and is corresponding one by one with button.
The invention has the beneficial effects as follows: the situation that is different from prior art, the present invention can control mobile phone shutdown by pressing at least two buttons simultaneously, make mobile phone shutdown become more effectively quick, avoided the user to solve mobile phone deadlock problem by pulling out battery of mobile phone.
The above only is embodiments of the invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to be done; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
