speaker is an acoustic signal device of an automobile. In the process of moving the car, the driver needs and requirements issued under the required acoustic signal to warn pedestrians and other vehicles due, to ensure traffic safety, but also for signal transmission line as a catalyst.
1. Horn Glossary
is the acoustic horn signal system of the vehicle. In the process of moving the car, the driver needs and requirements issued under the required acoustic signal to warn pedestrians and other vehicles due, to ensure traffic safety, but also for signal transmission line as a catalyst.
2. Horn works
When the steering wheel is pressed on the horn button or other location, the current from the battery will flow through the circuit of the solenoid coil horn relay, an electromagnetic coil to attract the movable contact of the relay switch is closed, current will flow at the horn . The electromagnet current operation of the internal speaker, so that the diaphragm vibration sound. .
3 Horn free
according to their pronunciation speaker horn sub-electric power of the gas horn; divided by a helical shape, and a cylindrical pot shaped three; according to the audio can be divided into treble and bass speaker; according to the wiring can be divided into a two-wire line system and the horn; according to whether the contact-type contacts can be divided into (general formula) and a non-contact electric horn (electronic) horn. Wherein the air horn mainly for heavy duty vehicles having air brake device, the electric horn has a simple structure, small size, light weight, easy maintenance and sweet voice features, which has been applied widely in small and medium sized vehicle. Electrical power according to their pronunciation speaker horn sub-speaker of the gas; divided by a helical shape, and a cylindrical cup-shaped three; according to the audio can be divided into treble and bass speaker; according to the wiring can be divided into two-wire line system and speaker; according to whether contact can be divided into a contact-type (general formula) and a non-contact electric horn (electronic) horns. Wherein the air horn mainly for heavy duty vehicles having air brake device, having a simple structure electric hornSingle, small size, light weight, sound sweet and easy maintenance features, which have been widely applied in the small and medium sized vehicles.
4. horn maintenance
● keep speaker clean appearance, each wire to secure.
● regular inspection, and a horn bracket fixed fastening screws ensure reliable grounding.
● method of fixing the horn greater impact on its pronunciation. In order to make a normal sound of the horn, the horn can not do a rigid mounting, thus fixing the holder on the buffer, i.e., between the speaker and the mounting bracket to be fitted with the leaf spring or rubber pad.
● frequently check the generator output voltage. Voltage is too high will burn horn contact, low voltage (below the speaker’s rated voltage) speaker will be unusual sounds.
● When washing, rinsing water can not be directly horn, the horn to prevent water from entering the speaker does not ring.
● horn in maintenance, to be noted that the position of each of the metal pads and an insulating mat, not installed wrong.
● continuous sound of the horn should not exceed 10s, so as not to damage the speakers.
5. The relevant legal provisions horn
● oncoming motor vehicle safety horizon sections sharp impact, etc., and the top ramp overtaking or in case of emergency, it should slow down and honk schematically. When
● vehicle ahead of the vehicle in case of slow moving or waiting in a queue, it should be allowed to wait or sequentially with, can not enter the non-motorized vehicles, traveling pavements, honking not urge vehicles and pedestrians.
In other words, the role of car horns, is the special sections of advance warning, a warning in certain emergency situations, in order to ensure traffic safety.
