For achieving the above object, the utility model provides a kind of motorcycle anti-theft phonetic alarm, at least comprise the speech production unit, filter amplification circuit, voice-output unit, the output of speech production unit is connected to the input of filter amplification circuit, the output of filter amplification circuit links to each other with the input of voice-output unit, key is: also comprise one according to angle change connection or an open circuited universal shockproof mercury switch and a double-cricuit supply unit, this mercury switch one end links to each other with the positive pole of power supply, the other end links to each other with amplifier and speech production unit in the filter amplification circuit, this double-cricuit supply unit comprises main with vehicle power and emergency battery power supply, and this emergency battery power supply is with main in parallel with vehicle power.Described voice-output unit is a loud speaker.
Described speech production unit is mainly by the sound pronunciation unit, constitute for the mu balanced circuit of sound pronunciation unit power supply and the oscillator of regulating the voice velocity of sound, this mu balanced circuit one end links to each other with power cathode, and the other end links to each other with positive source by universal shockproof mercury switch.This sound pronunciation unit is a speech chip.
Described universal shockproof mercury switch is sealed to form by electrically nonconducting material, be provided with the free rolling mercury bulb in it, its base is a turbination, and the both sides of base top are provided with the groove of symmetry, groove is provided with the pair of parallel lead, and lead links to each other with the speech production unit with power subsystem unit respectively.
The utility model adopts the universal shockproof mercury switch of purpose made to open and cut off audio alert, this mercury switch is sealed to form by electrically nonconducting material, in adorn one can be free movable mercury bulb, be provided with lead in the switch both sides, variation according to motor bike and vertical direction angle of inclination, mercury bulb contacts with the lead of side, and then turning circuit.Be exactly in detail, this mercury switch is stood or is started in the process at motor bike, as long as this car does not reach certain angle of inclination, mercury bulb just can contact wire, not conducting of circuit; And when the car overturning or when surpassing certain angle of inclination, such as with the angle of inclination of vertical direction greater than 60 °, mercury bulb contacts with lead; circuit turn-on; annunciator is started working, and plays caution stealer and the prompting car owner and the public's effect, and then plays the effect of protection car owner interests.
In addition; the utility model adopts active and standby power supply power supply with backup; generally with external automobile-used 12V power supply power supply, in case stealer cuts off automobile-used 12V power supply, this annunciator can adopt standby 12V powered battery; still can guarantee the phonetic alarm normal operation; parts such as control sound pronunciation chip and loud speaker, and standby 12V battery supply is difficult for destroyed in annunciator; play the effect of double insurance, more helped protecting user's economic interests.
Description of drawings
Fig. 1 is a circuit block diagram of the present utility model;
Fig. 2 is schematic circuit diagram of the present utility model;
Fig. 3 is the structural representation of universal shockproof mercury switch in the utility model.
The specific embodiment.
Below in conjunction with drawings and the specific embodiments the utility model is further described in more detail.
As shown in Figure 1, the utility model mainly is made of speech production unit, filter amplification circuit, voice-output unit and double-cricuit supply unit, and the double-cricuit supply unit links to each other with other circuit unit by a universal shockproof mercury switch, for it provides power supply.This double-cricuit supply unit comprises main with vehicle-mounted 12V power supply and emergency battery 12V power supply, and this emergency battery power supply provides the double copies power supply with main in parallel with vehicle power, after preventing stealer cut-out vehicle power, and the situation generation that annunciator can't normal operation.This speech production unit comprises mu balanced circuit, sound pronunciation unit and oscillator at least, and wherein, mu balanced circuit is used for the voltage stabilizing of 12V power supply to the 3V, to offer sound pronunciation cell operation voltage; Oscillator is used to regulate the velocity of sound that the sound pronunciation unit sends; The sound pronunciation unit can be a speech IC chip, also can be the voice combinational circuit that can generate the standard audio signal.Voice-output unit can be a loud speaker, or other has the voice output of same function.
Referring to shown in Figure 2, among the embodiment of the present utility model, resistance R 1 is formed mu balanced circuit with Zener diode W, the voltage stabilizing of 12V power line voltage is supplied speech chip A1 normal operation to 3V, resistance R 1 links to each other with the 2nd, 5 pin of A1 with diode W bonded assembly one end, the negative pole of diode W links to each other with 1 pin, the power cathode of A1, and the other end of R1 connects positive source by mercury switch SQ.Resistance R 2 constitutes the Rc oscillator with capacitor C 1, is used for regulating the velocity of sound that A1 sends voice, and R2 links to each other with the 3rd pin of A1 with C2 bonded assembly one end, and the other end of R1 connects 5 pin of A1, and the other end of C2 connects power cathode.A1 is speech IC chip OX-209 in the present embodiment, can send such as sound signals such as " bad, the thief have scrounged, and stops thief soon ".
