Brief description of the drawings

Fig. 1 is the structural representation of Anti-theft alarm of bicycle.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model example is carried out clear Chu, it is fully described by.

Referring to Fig. 1, a kind of Anti-theft alarm of bicycle, including power supply G, unidirectional thyristor VS, shock transducer SQ1, Mercury electro-conducting control switchs SQ2, small-sized lock-controlled switch SA, chip IC 2, loudspeaker BL, chip IC 1, resistance R1, electric capacity C1 and voltage-stabiliser tube VD；The small-sized lock-controlled switch SA of power supply G connections, small-sized lock-controlled switch SA connections mercury electro-conducting control switchs SQ2, mercury electro-conducting control switch SQ2 connections shock transducer SQ1, shock transducer SQ1 connection unidirectional thyristor VS, unidirectional thyristor VS connection chip IC 2 1st pin；The 5th pin connection loudspeaker BL of the chip IC 2, the 8th pin of loudspeaker BL connections chip IC 2, the 3rd pin and the 6th pin Ground connection, the 2nd pin connection resistance R3 and electric capacity C3, electric capacity C3 connections electric capacity C2, electric capacity C2 are connected in parallel resistance R2, resistance R2 connections The OUT pin of chip IC 1；The Vss pin ground connection of the chip IC 1, OSC pin connection resistance R1 and electric capacity C1, electric capacity C1 connection voltage stabilizings Pipe VD；The model HL-169B of chip IC 1, the model TDA7052 of chip IC 2.

Operation principle of the present utility model is：Referring to Fig. 1, the utility model Anti-theft alarm of bicycle, voice is integrated IC circuit 1 and resistor R1, capacitor C1 etc. constitute speech synthesizer, audio ic IC2 and peripheral capacitance resistance component Constitute power amplifier, unidirectional thyristor VS and shock transducer SQ1, mercury electro-conducting control switch SQ2 constitute trigger switch, Small-sized lock-controlled switch SA constitutes locking power switch；When owner leaves the bicycle come to a complete stop, while first-class lock, use Special key closure alarm locking power switch SA, alarm is on the alert into people；Now, circuit does not consume actually Electricity；When bicycle is stolen, the vibration produced with picking lock, shock transducer SQl is discontinuously connected, and unidirectional thyristor VS is to obtain tactile Voltage turn-on and self-locking are sent out, ICl obtains electric work；Storage analog voice electric signal in IC1 outputs, after R2, C2 LPF, by C3 Misfortune is bonded to IC2 and carries out Audio power amplifier, finally promotes loudspeaker BL to send loud " catching a thief ... " yell, if burglar Picking lock is not removed, and is attempt to bicycle of stealthily moving, with the slightly change of car body position, mercury electro-conducting control switch SQ2 connects automatically It is logical, it can equally turn on VS, alarm sounding；If thief has found alarm first, it is intended to pound, prize and destroy, can equally produce Raw vibration or displacement triggers circuit are sounded the alarm, at this moment only owner's shut-off lock-controlled switch SA, and alarm can be just released from.
