Abstract
The utility model relates to a mobile phone sleeve with vibration alarm, which is placed on the waist and is used for the anti-theft of the mobile phone. The utility model comprises a box body and a clamshell which is connected with the box body. The box body is provided with a belt hole, which is used for the passing through of a belt. The clamshell and the box body are connected by a strong magnetic hasp. An electric line is arranged between the leather surface and the lining material of the box body; the electric line can produce vibration alarm by an eccentric motor. The magnetic hasp is the switch of the line; a button battery is a power supply. The utility model is characterized in that a call vibration circuit is also arranged between the leather surface and the lining material of the box body. The electric circuit consists of a mobile phone calling back electromagnetic wave receiving antenna and a corresponded coupling capacitance. A signal is sent to the driving electric circuit of the eccentric motor after amplifying by an amplifier circuit. The amplifier circuit comprises a two stage triode. The utility model has the advantages of responsive and easy to be operated.
Description
Affiliated technical field
The utility model relates to a kind of cell-phone cover with vibration alarming, is applied to hang over the antitheft of mobile phone between waist.
Background technology
Existing cell-phone cover is one just in time can load the leatherware square box of corresponding mobile phone, and it is made up of box body and renovating of being attached thereto; Have a belt eye that supplies waistband to pass on the box body.Renovate and box body between connect by strong magnetic hasp.For antitheft, people install the warning electronic circuit between box body surface and lining material.This circuit is a switch with the magnetic hasp, is power supply with the twist button battery, as long as the switch hasp is opened, just starts antitheft circuits for triggering, promotes the eccentric motor operation and produces vibration.Its deficiency be the mobile phone that has when not having the calling vibration function in the big place of noise, can't make the generation vibration of cell-phone cover, remind the machine master that incoming call is arranged.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, and a kind of cell-phone cover of the vibrative band vibration alarming of sending a telegram here is provided.
The purpose of this utility model can reach like this: a kind of cell-phone cover with vibration alarming, form by box body and renovating of being attached thereto; Have a belt eye that supplies waistband to pass on the box body; Renovate and box body between connect by strong magnetic hasp; Install the electronic circuit that eccentric motor produces vibration alarming between box body surface and the lining material, this circuit is a switch with the magnetic hasp, is power supply with the twist button battery, it is characterized in that also being provided with between box body surface and the lining material calling vibration circuit; This circuit replys the electromagnetic wave reception antenna by cell phone incoming call and corresponding coupling capacitance is formed; Signal outputs to the drive circuit of eccentric motor after the amplifying circuit that the twin-stage triode is formed amplifies.
The utility model has following advantage compared to existing technology: is quick on the draw, and simple to operate.
Description of drawings
Accompanying drawing is an electronic-circuit diagram of the present utility model.
Among the figure L be antenna C be coupling capacitance R1 be biasing resistor R2 be load resistance R3 be coupling resistance Q1 high frequency amplifying triode Q2 be shaping amplifying triode R7 be load resistance D be high-frequency diode R4, R5, R6 for supplying resistance K1 be that to come electric switch Q3, Q4 be that complementary amplifier tube M is an eccentric motor to anti-theft switch K3 magnetic hasp K switch 2
Embodiment
The utility model is further described below in conjunction with accompanying drawing.A kind of cell-phone cover with vibration alarming, mountain box body and the composition of renovating that is attached thereto; Have a belt eye that supplies waistband to pass on the box body; Renovate and box body between connect by strong magnetic hasp; Install the electronic circuit that eccentric motor produces the dirt vibration alarming between box body surface and the lining material, this circuit is switch (K3) with the magnetic hasp, with the twist button battery be power supply (+3V), it is characterized in that also being provided with between box body surface and the lining material calling vibration circuit; This circuit replys electromagnetic wave reception antenna (L) by cell phone incoming call and corresponding coupling capacitance (C) is formed; Signal outputs to the drive circuit of eccentric motor M after the amplifying circuit that twin-stage triode (Q1, Q2) is formed amplifies.When K1 is closed, the guarding portion circuit working, need only K3 this moment is that magnetic hasp is raised, Q3, Q4 conducting, M work.When K2 is closed, the calling vibration circuit working.At this moment, when cell phone incoming call, after the coupling of its answer electromagnetic wave through antenna L reception and coupling capacitance C, amplify, through the shaping of R3 coupling and Q2, after diode D rectification, output to the eccentric motor operating circuit again by Q1.The parameter of above-mentioned Q1, Q2, Q3, Q4 is respectively 9018,9012,9013,9012.
