Abstract
Disclosed is a cellphone sock with alarm against theft function, which belongs to an accessory of the cellphone, and aims at providing an alarm against theft function for the cellphone sock. The structure of the utility model is that a pair of magnetic buttons 2 that can be attracted to each other by magnetic force is arranged on a cellphone sock body 1 and a cellphone sock cover 3; a magnet 5 is arranged in the magnetic buttons 2 on the cellphone sock body 1; an alarm against theft circuit 4 which is controlled to be connected and disconnected by a dry reed tube is arranged at the magnetic buttons 2 of the cellphone sock cover 3. The main purpose of the utility model is that when the cellphone is arranged in the cellphone sock and the cellphone sock cover is closed, the pair of magnetic buttons are attracted to each other by the magnetic force, the alarm against theft circuit 4 in the dry reed tube 6 is disconnected by the effect of the magnetic field, the alarm against theft circuit 4 does not alarm; when the cellphone sock cover 3 is opened, the dry reed tube 6 loses the magnetic field effect and connects with the alarm against theft circuit 4 to alarm to remind the cellphone user to take necessary measure.
Description
(1) technical field:
The utility model relates to a kind of annex of mobile phone, is meant a kind of anti-theft alarm mobile phone cover especially.
(2) background technology:
The cell-phone cover that uses mainly has the mobile phone of carrying or functions such as the protection mobile phone is not frayed, extruding at present, does not have functions such as burglar alarm.
(3) summary of the invention:
The purpose of this utility model provides a kind of anti-theft alarm mobile phone cover that simple optional equipment can reach the burglar alarm purpose of setting up on cell-phone cover.
Major technique content of the present utility model is to comprise mobile phone body, mobile phone upper shield, it is characterized in that but mobile phone body and cell-phone cover cover the magnetic clasp that a pair of adhesive is installed, magnet is located in the magnetic clasp on the mobile phone body, and the anti-theft warning circuit by tongue tube control break-make is installed at the magnetic clasp place of mobile phone upper shield.
Operation principle of the present utility model is to place cell-phone cover and cover the mobile phone upper shield when making a pair of magnetic clasp adhesive when mobile phone, and the tongue tube in the anti-theft warning circuit is disconnected by the effect in magnetic field, and anti-theft warning circuit is not reported to the police; When the mobile phone upper shield was opened, tongue tube lost the action of a magnetic field and connects anti-theft warning circuit and warning, reminded the phone-holder to take measures necessary.
Advantage of the present utility model is can reach the purpose of burglar alarm by set up simple optional equipment on cell-phone cover.
(4) description of drawings:
Fig. 1 is a side sectional view of the present utility model;
Fig. 2 is a front view of the present utility model;
Fig. 3 is the anti-theft warning circuit figure by tongue tube control break-make of the present utility model.
(5) embodiment:
The utility model as shown in Figure 1 and Figure 2, mainly by mobile phone body 1, magnetic clasp 2, mobile phone upper shield 3, form by the anti-theft warning circuit 4 of tongue tube control break-make, magnet 5 etc., wherein, but the magnetic clasp 2 of a pair of adhesive is installed on mobile phone body 1 and the mobile phone upper shield 3, magnet 5 is located in the magnetic clasp 2 on the mobile phone body 1, and the anti-theft warning circuit 4 by tongue tube control break-make is installed at magnetic clasp 2 places of mobile phone upper shield 3.
By the anti-theft warning circuit 4 of tongue tube control break-make as shown in Figure 3, the positive pole of power supply E passes through K switch, tongue tube 6 is connected with the resistance R 1 of collector electrode and base stage with in parallel with the collector electrode of triode Q1, and be connected with first pin of audio manifold block 7, the base stage of triode Q1 connects resistance R 2, resistance R 2 and the crus secunda that is connected to audio manifold block 7 after diode D is connected in series, emitter series resistance R3 at triode Q1 and Q2, R4, resistance R 3, the positive pole that connects capacitor C between the R4, the negative pole of capacitor C connects an end of buzzer 8, the other end of buzzer 8, the crus secunda of audio manifold block 7, the collector electrode of triode Q2 is connected with the negative pole of power supply E in the lump.
When the needs anti-theft alarm function, K switch is arranged to normal open state; If when not needing anti-theft alarm function, K switch is arranged to off-state gets final product.
