Abstract
The invention discloses a double-frequency warning-sound-selectable automobile horn device. The double-frequency warning-sound-selectable automobile horn device comprises a first switch, a second switch, a voice chip, a horn and a loudspeaker. One end of the first switch is connected with the positive pole of a power supply, and the other end of the first switch is connected with a relay, the horn and the negative pole of the power supply in sequence to form a first line way. The input end of the voice chip is connected with the second switch, the output end of the voice chip is connected with one end of the loudspeaker through an audion, the other end of the loudspeaker is connected with the negative pole of the power supply, and the second switch, the voice chip, the audion and the loudspeaker form a second line way. According to the double-frequency warning-sound-selectable automobile horn device, different horn honking ways can be chosen aiming at different traffic conditions, noise generated under the condition that the horn must be honked to warn a pedestrian at a moment which is not suitable for honking is solved, frightening on the pedestrian is avoided, and social harmony is promoted; the chord sound warning of the automobile is full of diversification and entertainment, the advantages of being convenient and practical are possessed, and the application and popularization are facilitated.
Description
Technical field
The present invention relates to a kind of auto horn device, be specifically related to the optional caution sound auto horn device of a kind of double frequency.
Background technology
At present, day by day universal along with automobile, motor vehicles in use amount sharply increases, people go around in any public place leisurely and comfortablely, bow when seeing the mobile phone or be absorbed in other thing, all likely cause the impact on vehicle pass-through, at this moment just inevitably often hear that vehicle presses suddenly ear-piercing loudspeaker aloud with oneself, thus scaring is caused to self, young man may also have certain resistibility for this baffled scaring, if child or the elderly, may be had a strong impact on by precipitate this ear-piercing sound of horn, serious even threat to life.Sometimes, after driver also knows blast the horn in fact, ear-piercing sound brings scaring can to in-plant pedestrian, but blast the horn just can not play reminding effect.
Summary of the invention
Goal of the invention: in order to overcome the deficiencies in the prior art, the invention provides the optional caution sound auto horn device of a kind of double frequency, by different circuits can be selected to use different loudspeaker to remind pedestrian under different road conditions conditions, reduces noise emission.
Technical scheme: for solving the problems of the technologies described above, the optional caution sound auto horn device of a kind of double frequency of the present invention, comprise the first switch, second switch, speech chip, loudspeaker and loud speaker, described first switch one end is connected with positive source, and the first switch other end connects to form first line with relay, loudspeaker and power cathode successively; The input end of described speech chip is connected with second switch, and the mouth of speech chip is connected with loud speaker one end by aerotron, and the loud speaker other end is connected with power cathode, and second switch, speech chip, aerotron and loud speaker form the second circuit.
As preferably, between described first switch and power cathode, be connected with infrared acquisition switching device and velocity response switching device in turn.
As preferably, between the input end of described speech chip and positive source, be provided with the first electric capacity.
As preferably, between the mouth of described speech chip and positive source, be provided with the second electric capacity.
Principle of the present invention: when ringing loudspeaker, first, under normal circumstances, can be selective, a kind of is traditional sound of horn, another kind is gentle chord phonetic warning, some horn-blowing control regions or pedestrian and car closely time, select chord musical sound, alleviate noise emission, and stop the generation of frightening result, secondly, when the speed of a motor vehicle is less than 20km/h, and infrared detection device is when having a pedestrian within monitoring right ahead or 5 meters, front, side, velocity response switching device and infrared acquisition switching device switch close, now, no matter press the first switch, or second switch, then can only send chord voice message, the generation of maloperation is avoided with this.
Beneficial effect: the optional caution sound auto horn device of double frequency of the present invention, different ring loudspeaker modes can be selected for different traffic conditions, or can only phonetic warning be had under special traffic situation, by the change of sound, solve the noise but wanting blast the horn to warn pedestrian to produce in the moment that is unsuitable for blowing a whistle, and avoid the scaring to pedestrian, facilitate social harmony, and because the warning of automobile polyphonic ring tone is full of variation and interest, convenient and practical, be conducive to promoting the use of.
Accompanying drawing explanation
Fig. 1 is schematic circuit diagram of the present invention.
Fig. 2 is adjustable prompting sound circuit structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described.
As depicted in figs. 1 and 2, the optional caution sound auto horn device of a kind of double frequency of the present invention, comprise the first switch S B1, second switch SB2, speech chip SIC, horn in H 1 and loud speaker H1, described first switch S B1 one end is connected with positive source, and the first switch S B1 other end connects to form first line with relay R E, horn in H 1 and power cathode successively, the input end of described speech chip SIC is connected with second switch SB2, the first electric capacity C1 is provided with between the input end of described speech chip SIC and positive source, the effect of the first electric capacity C1 is the noise signal that elimination first switch S B1 responds to when going between long, the mouth of speech chip SIC is connected with loud speaker H1 one end by aerotron TR, the loud speaker H1 other end is connected with power cathode, speech chip SIC is connected with positive source and power cathode respectively, the second electric capacity C2 is provided with between the mouth of described speech chip SIC and positive source, second switch SB2, speech chip SIC, aerotron TR and loud speaker H1 forms the second circuit.Be connected with infrared acquisition switching device, velocity response switching device, speech chip SIC, aerotron TR and loud speaker H1 between described first switch S B1 and power cathode in turn and form tertiary circuit, when infrared search switch device D1 find out within the scope of front side 5 meters have pedestrian time, internal switch closes, now, if when the speed of a motor vehicle is lower than 20km/h, velocity response switching device S1 internal switch also will close, form path thus, now, no matter press SB1 or SB2, all can only send chord phonetic warning sound.With avoid by mistake by generation.Speech chip is provided with sound adjusting knob MK, phonetic warning sound pattern select undertaken by sound adjusting knob MK, totally four groups available.
The present invention in use, each car is all provided with the present invention.When the section of running car at residential quarters road or no tooting, pedestrian is had closely to stop before running into, by second switch SB2, form close circuit, external speaker H1 sends soft chord sound, and style design musical sound as each in " you are good, please allow ", " excuse me once; thanks ", " For haven's sake, to bar road " etc. is reminded.When travelling at normal road, by the first switch S B1, can at this moment send sound of blowing a whistle normally, reaching the prompting under traditional consciousness or alarming effect.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
