The parent device comprises a parent device shell, a battery, and a parent circuit; the battery and the parent device circuit is arranged inside the parent device shell; the parent device circuit comprises a high frequency radio receiving integrate circuit RX3310A-03, a audio oscillator, a piezoelectric ceramic piece, the 2 feet of the a high frequency radio receiving integrate circuit RX3310A-03 is connected with the audio oscillator IC3; the output end of the audio oscillator IC3 nand gate 4 is directly connected with the piezoelectric ceramic piece. When the mobile phone is away from the owner's controllable range, the parent device with the owner will give an alarm sound to remind the owner.
Description
Technical field
The utility model relates to a kind of warning device, relates to a kind of mobile phone burglar alarm specifically.
Background technology
At present, collect more and more universal, the loss of collection and stolen also more and more, when the loss of mobile phone with when stolen, owner's imperception.
Summary of the invention
At above deficiency, the utility model purpose is to provide a kind of handset anti-theft alarm to strengthen device, and when mobile phone left owner's control range, the machine tool of following owner will send chimes of doom and remind owner to note.
To achieve these goals, the technical solution of the utility model is: mobile phone burglar alarm, it is characterized in that forming by machine tool and handset, and handset is positioned on the mobile phone, and machine tool is worn by owner; Handset comprises the handset circuit, and the handset circuit comprises high frequency radio emission integrated circuit TX4915-T2.
Machine tool is made up of machine tool housing, battery, machine tool circuit, and battery, machine tool circuit are positioned at the machine tool housing; The machine tool circuit comprises high frequency radio receiving integrate circuit RX3310A-03, audio frequency oscillator, piezoelectric ceramic piece, and 2 pin of high frequency radio receiving integrate circuit RX3310A-03 link to each other with audio frequency oscillator IC3; The output of the NAND gate 4 of audio frequency oscillator IC3 directly is connected with piezoelectric ceramic piece.
Described handset is positioned at mobile phone.
Described handset is made up of handset housing, battery, handset circuit, and battery and handset circuit are positioned at the handset housing, and handset is suspended on the mobile phone by rope.
Described handset is provided with switch.
Described machine tool is provided with switch.
The utility model utilizes electromagnetic wave mobile phone firmly to be controlled in owner's the control range within (5 meters), in case mobile phone exceeds owner's control range, alarm can be reported to the police, and reminds owner to note.The utility model also can be used for leather trunk, wallet, jewellery etc. and returns the antitheft of other valuables and prevent many aspects such as children loss.

Embodiment
As shown in Figure 1 and Figure 2, mobile phone burglar alarm is made up of machine tool, handset, and handset is positioned on the mobile phone, and machine tool is worn by owner; Handset comprises the handset circuit, and the handset circuit comprises high frequency radio emission integrated circuit TX4915-T2.
Machine tool by machine tool housing, battery, raise circuit and form, battery, machine tool circuit are positioned at the machine tool housing; The machine tool circuit comprises high frequency radio receiving integrate circuit RX3310A-03, audio frequency oscillator, piezoelectric ceramic piece, and 2 pin of high frequency radio receiving integrate circuit RX3310A-03 link to each other with audio frequency oscillator IC3; The output of the NAND gate 4 of audio frequency oscillator IC3 directly is connected with piezoelectric ceramic piece.Described handset is provided with switch.Described machine tool is provided with switch.
Described handset is made up of handset housing, battery, handset circuit, and battery and handset circuit are positioned at the handset housing, and handset is suspended on the mobile phone by rope.
The utility model is made of machine tool and handset.Machine tool is worn by owner, and handset hangs on the mobile phone.When owner with oneself mobile phone away from the time machine tool chimes of doom that will " tick, tick ... ", to arouse attention.
As shown in Figure 1, IC1 is high frequency radio emission integrated circuit TX4915-T2, and it can finish the function of pulse modulation vibration and emission, and carrier frequency is 315KHz, can not cause interference to other any wireless devices, also is difficult to be disturbed by other equipment.
As shown in Figure 2, IC2 is high frequency radio receiving integrate circuit RX3310A-03, and it comprises circuit such as wireless receiving, demodulation.When IC2 can receive the radio wave that is sent by handset, logic output terminal the 2nd pin of IC2 was a low level.NAND gate 1,2 component frequencies are the ultralow frequency controlled oscillator of 0.5-1Hz; NAND gate 3,4 is formed the audio frequency oscillator of 1Kz.The output of NAND gate 4 directly drives piezoelectric ceramic piece HTD and sends chimes of doom.
When handset and machine tool close together, in the time of in 5 meters, the low electricity frequency of the 2nd pin of machine tool IC2 output, HTD alarm free sound.And when handset and machine tool distance during greater than 5 meters, IC2 in the machine tool is very weak because of the radio or the electric wave that can't accept handset and send, at this moment, IC2 can not normally decipher, its the 2nd pin will be exported high electricity frequently, thereby the low-frequency oscillator starting of oscillation that NAND gate 1,2 is formed, the audio frequency oscillator that modulation NAND gate 3,4 is formed produces intermittently concussion, makes HTD send chimes of doom.
