According to the connection mode can be divided into single line and double line system horn;
According to whether the contact can be divided into contact (common type) electric horn and contactless electric horn (electronic).
Among them, the air horn is mainly used for heavy truck with air braking device, electric horn has the advantages of simple structure, small size, light quality, sweet voice and repair convenience features, and thus has wide application in the small vehicle.
The car horn to care?
(1) keep horn clean appearance, the connection should be firmly.
(2) the fixed screws, often check fastening horn and the support, ensure the reliable grounding.
(3) the effect of fixed method of the large horn pronunciation. In order to make the trumpet sound normal, horn can not do rigid mounting, and therefore to be fixed in the buffer bracket, namely, be equipped with sheet spring or rubber pad between the speaker and the fixed bracket.
(4) often check the output voltage of the generator. The voltage is too high will burn out the horn contact, the voltage is too low (below the rated voltage of the horn horn) will be issued abnormal sound.
(5) wash, water can not be directly flushing the megaphone, lest the water into the microphone and make the horn does not ring.
(6) in the maintenance of speakers, should pay attention to the metal pad and the insulating pad position, do not install the wrong.

Work 7, horn in the car at low speed, associated with the battery work, if the energy of battery is reduced, the horn sound is reduced, to check the battery charge capacity is normal.
The car horn daily matters needing attention:
1 car horn that prevent being wet, found the water as soon as possible with the wind blowing the horn.
2 do not always long time horn, it is easy to cause the horn contact early ablation.
3 horn failure to seek professional repair technicians to help, do not blindly replacing horn, easy to cause unnecessary waste.

The car horn does not ring or a different sound how to do? Car speaker how to carry out routine maintenance and self repair horn above failure, should distinguish is the fault of a line fault or a speaker.
