Description
Technical field
The utility model relates to a kind of annunciator, especially relates to a kind of full automatic vehicle burglar alarm that has deterrent effect.
Background technology
An integrated chip is arranged in the general electronic car Car Burglar Alarm, and there are some switches the inside, and when adding a trigger voltage, the switch door is just opened positive electricity of output and is pressed onto driving circuit, infers actuating unit and warning circuit.External voltage leans on sensor or switch to finish, and has disguise and infrangibility, and electronic automobile generally all is the Car Burglar Alarm of former factory band, and principle and electronic anti-theft device are roughly the same, are that circuit is implicative of each other, mainly are locked launching systems.Just the network theftproof device can also send on car owner's the mobile phone stealing feelings, and possess the ability of locked launching system except having than the stronger function of electronic anti-theft device.Its Mobile Phone Locating can be vehicle location in certain scope.But they do not steal some lawless person car but steal the treasure and the tire of car the inside, and they finish crime in very short time like this, and he runs away already when waiting car owner to come.
The sound of taking metal to scrape glass can make the people feel bad, and people are called this sound the Metal Cutting sound (" blackboard screech ") of blackboard.Northwestern Univ USA's Neuroscience Research the research of this sad and shrill sound is started from 1988.Natural sound has many cycles to concentrate formation, what can cause that the offending reason of people's sense of hearing at first suspects is the cycle height, sound in cycle 1000HZ～2000Hz scope, the sound of 1000Hz probably approaches the descant territory in soprano's Western style of singing, excision is fallen, and the result makes us uneasy from head to foot sound not to have been had.This sound and natural sound are compared, and the result is surprised to find that the birdie that a kind of monkey sends (warning sound) is similar to stroke applicator of this Glass blackboard when discovering in critical condition.Having accepted this experimental result infers later on, we are in the horrent uneasy sensation of hearing that this sound occurs later on, perhaps be we mankind have just learned " memory in time immemorial " when walking on two legs, promptly waken us up and be sunk into sleep and remember near time immemorial of for a long time " have dangerous situation to exist ".Just the mankind still residual during evolution so a kind of conditioned reflex, this sound seriously stimulates cerebral cortex and ear-drum, makes cerebral cortex too nervous, normal effect affects the nerves.
Its anti-theft feature of present Car Burglar Alarm is very strong, but is had an opportunity to take advantage of by the lawless person, mainly is because annunciator is in the dock, and only plays the warning effect, does not play protective action.
