Description
Technical field
The invention belongs to the vehicular electrical equipment technical field, particularly relate to a kind of automobile horn system.
Background technology
In order to warn other vehicle and pedestrian, all be equipped with horn system on the vehicle.Present horn system mainly is the electric horn [1] of electromagnetic type and electronic type, although their actual form is different, their theory of constitution is similar; As shown in Figure 3: the volume of loudspeaker C is low; The volume of loudspeaker D is high, and in different environment, controller C makes different sound horn.Owing to when the sound of loudspeaker plays warning function, also can bring the pollution noise to environment, in order to reduce the harm that the ring loudspeaker bring to environment, China has all made relevant provisions in a lot of cities, like document [2].However; The thing that car horn disturbs residents still often takes place, and the basic reason that causes this phenomenon mainly is two, and the one, the quality of human pilot is not high; In order to let other people dodge random ring loudspeaker, the 2nd, at special circumstances (situation about providing like the traffic law) caution passerby or other vehicle." caution " and " disturbing residents " is a pair of contradiction; Present horn for vehicle system can't separate the two fully; In order to reduce the noise pollution that horn for vehicle causes environment; Improve people's live and work environment, design a kind of and play " caution " effect, and can not cause the novel automobile horn system of noise pollution imperative environment.

Summary of the invention
Technical problem to be solved by this invention provides a kind of automobile horn system, when guaranteeing the loudspeaker alarm function, reduces noise pollution.
The technical solution adopted for the present invention to solve the technical problems is: a kind of automobile horn system is provided; Comprise sonification system, receiving system; Described sonification system comprises controller A, signal generator A, power amplifier A, loudspeaker A, frequency shifter A, acoustical generator; Described controller A connects signal generator A; Connect loudspeaker A behind an output process of the described signal generator A power amplifier A, No. two outputs of described signal generator A connect frequency shifter A, and described frequency shifter A connects acoustical generator; Described receiving system comprises transducer, controller B, frequency shifter B, power amplifier C, loudspeaker B; Described transducer connects frequency shifter B input; Controller B connects frequency shifter B control end; Described frequency shifter B output connects power amplifier C, and described power amplifier C output connects loudspeaker B.
Connect acoustical generator behind the described frequency shifter A process power amplifier B.
Described transducer is one or more.
Connect frequency shifter B input behind described transducer process preamplifier and the filter.
Described power amplifier C output also is connected with display unit.
In order to solve existing automobile horn system to the noise pollution problem that environment produces, what at first will do is exactly the warning function (promptly main effect) and the problem that disturbs residents (side effect) of automobile horn are separated.The object that the driver will warn has two types, the personnel of the first kind to liking the pedestrian or driving bicycle, motorcycle, and second class object is the driver of other vehicle.For first kind object, generally do not need too big volume can play effect, therefore to accomplish that this point can't cause big noise pollution to environment; For second class object, because they are in the driver's cabin,, play warning function to them and then need adopt bigger volume with the obstruct that car body is arranged between the external world, this will certainly bring noise pollution to environment.Vibration is propagated just in air can form sound; People's ear is different to the sensitivity of different frequency sound; The sound frequency that common people can hear is at 20～20000Hz; Just can not cause noise pollution to environment as long as will be used to warn the frequency shift of vehicle driver's loudspeaker to the insensitive frequency domain of people's ear, in driver's cabin, increase by one simultaneously and receive and the device of conversion sound frequency, the sound that the sound conversion adult ear of the insensitive frequency of people's ear that receives can normally be heard gets final product.
Beneficial effect
The present invention is through the method for shift frequency, when guaranteeing the loudspeaker alarm function, reduces noise pollution, thoroughly solved the noise that horn for vehicle the brought problem that disturbs residents, and brought the huge social benefit; In addition, the present invention need not expensive original paper, and cost is low, effective, can be enterprise and brings huge economic benefit.
