Embodiment
Mobile phone alarm device of the present invention, mobile phone and mobile phone alarming method, by using battery of mobile phone to charge as supply module, when the conducting control module detects this battery of mobile phone and is pulled out, being electrically connected between conducting supply module and the alarm module, provide power supply by supply module for alarm module, realize reporting to the police.
Mobile phone alarm device of the present invention comprises as shown in Figure 1:
Conducting control module 13 is used for the detection of handset battery and pulls out operation, and when detecting battery of mobile phone and pulled out, the electrical connection of conducting supply module 12 and alarm module 11.
At this, this supply module can be a pure energy-storage units 121, only carries out the storage of electric energy.
Yet, in some specific situation, under the extremely low situation of cell-phone battery electric-charge quantity, if energy-storage units 121 is only arranged, this moment, energy-storage units 121 meetings be discharged to the battery of mobile phone direction, in this case, if hand-set from stolen, the electric weight in the possible energy-storage units 121 is not enough to keep alarm module 11 to be continued to report to the police; Simultaneously, also in order to prevent that limited electric energy in this energy-storage units 121 from being that other module in the mobile phone is used, therefore, as shown in Figure 1, further is provided with in the supply module 12 of the present invention:
Isolated location 122 is connected between energy-storage units 121 and the battery of mobile phone,, isolates to the battery of mobile phone direction at energy-storage units 121 to the unidirectional conducting of energy-storage units 121 directions at battery of mobile phone.
After isolated location 122 is set, energy-storage units 121 can utilize the electric weight of battery of mobile phone to charge, storage is for the electric energy of alarm module 11 operate as normal, simultaneously, because the unidirectional conduction of isolated location 122, electric energy stored is with regard to higher level of energy long term maintenance in the energy-storage units 121, simultaneously, after battery of mobile phone was removed, the electric weight of this energy-storage units 121 also only can guarantee the warning of the continuous and effective of alarm module 11 with this for alarm module 11 uses.
Simultaneously, as shown in Figure 2, this conducting control module 13 specifically comprises:
Detecting unit 131 is used for changing generation relevant detection signal according to the level after the mobile phone power down;
Mobile phone alarming method of the present invention comprises as shown in Figure 2:
As shown in Figure 3, supply module of the present invention 12 is concrete to adopt the connect mode of first capacitor of diodes to realize, wherein:
This first capacitor can be to be mineral condenser, organic dielectric capacitor or electrolytic capacitor.
This diode guarantees that capacitor can not be oppositely to the battery of mobile phone discharge, and simultaneously, after the assurance power down, the electric energy in first capacitor can be used for mobile phone alarm device.
This conducting control module 12 specifically comprises:
First resistance and second resistance of series connection, as detecting unit, first resistance, one end is connected with battery of mobile phone, an end ground connection of second resistance;

At this, this field effect transistor can be MOSFET (metal-oxide-semiconductor field effect t), also can be JFET (technotron).
In the normal state, first capacitor utilizes charging mobile phone battery, and be connected with battery of mobile phone with second resistance as first resistance of the series connection of detecting unit, the normal voltage of sampling battery of mobile phone, therefore, the source electrode of field effect transistor and the pressure reduction between the grid are lower than conducting voltage, and the source electrode and the drain electrode of field effect transistor are in off-state;
In case battery of mobile phone is taken, the grid voltage of field effect transistor by second resistance drop-down be 0, therefore, the source electrode of field effect transistor and the pressure reduction between the grid are greater than conducting voltage, cause the source electrode and the drain electrode of field effect transistor to be in conducting state, at this moment, capacitor begins by this field effect transistor to the warning circuit module, alarm module enters operating state, sends alarm sound.
At this, this alarm module is a buzzer.
The present invention further adds one second capacitor in conducting control module 13, this second capacitor, one end ground connection, and the other end is connected between the drain electrode and alarm module of field effect transistor, is used for stablizing the alarm module operating voltage.
The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
