Embodiment
As shown in Figure 1 and Figure 2, lost-proof cell phone 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 six phase inverter ics
1, long wave radio emission integrated circuit (IC)
2, six phase inverter ics
1By not gate 3 and long wave radio emission integrated circuit (IC)
2 Input 3 pin be connected long wave radio emission integrated circuit (IC)
2Inside is provided with concealed antenna;
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 long wave radio receiving integrate circuit IC
1, audio phase locking ring decoder IC
2, ultralow frequency controlled oscillator, audio frequency oscillator, piezoelectric ceramic piece, long wave radio receiving integrate circuit IC
13 pin and audio phase locking ring decoder IC
2Input 3 pin be connected audio phase locking ring decoder IC
2Output 8 pin be connected with ultralow frequency controlled oscillator, audio frequency oscillator; The output of the not gate 4 of audio frequency oscillator directly is connected with piezoelectric ceramic piece.Described handset is provided with switch.Described machine tool is provided with switch.
Described handset is positioned at mobile phone.
Described handset is made up of handset housing, battery, handset circuit, and battery, 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 will send the chimes of doom of " tick, tick ... ", to arouse attention.
As shown in Figure 1, IC1 is six phase inverter CD 4069, and not gate 1,2 is wherein formed the low-frequency oscillator of 10KHz, and low frequency signal adds input 3 pin of IC2 after not gate 3 bufferings, radio carrier is modulated.IC2 is long wave radio emission application-specific integrated circuit (ASIC) T630, and it can finish the function of pulse modulation vibration and emission, and carrier frequency is 150KHz, and transmitting power is in the milliwatt level, and there is concealed antenna IC2 inside, can satisfy effective control of 5m.Simultaneously circuit work frequency is located at 150KHz, can cause interference, also be difficult to be disturbed by other equipment to other wireless devices.
As shown in Figure 2, IC1 is that long wave radio receives application-specific integrated circuit (ASIC) T631, and it comprises circuit such as wireless receiving, demodulation.When the 1st pin of IC1 receives the radio wave that is sent by handset, after demodulation, at the low frequency signal of the 3rd pin output 10KHz.The low frequency signal of 10KHz is sent into input the 3rd pin of IC2 audio phase locking ring decoder LM567, when the decoding frequency of being determined by external timing components and parts RP1 of IC2 and C4 is f
0When consistent with input signal, logic output terminal the 8th pin of IC2 becomes 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 1KHz.The output of NAND gate 4 directly drives piezoelectric ceramic piece HTD and sends chimes of doom.
When handset and machine tool close together, when the 5m left and right sides, the 8th pin output low level of machine tool IC2, HTD alarm free sound.And when handset and machine tool distance during greater than 5m, IC1 in the machine tool is very weak because of the radio or the electric wave that can not receive handset and send, at this moment, IC2 can not normally decipher, its the 8th pin can be exported high level, thereby the ultralow-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, and HTD is sounded the alarm.
