Many car owners have reflected that the sound of the horn is low after the car rain, the sound of the sound is faint, and the bass is loose, and the connection is also poor. What is the reason?
First, let’s first understand how the car horn works.
When we press the horn button, the current of the battery flows to the electromagnetic coil, in turn, attract the electromagnetic relay contacts are closed, the current is transmitted to the car horn, so that the interior of the horn solenoid to work, and push the diaphragm vibration sound.
Three reasons why the sound of the horn is low after the car rains
Cause one: internal contact is not good
According to the working principle of the horn, once the contact of the contact is not good, it will not sound when the horn is sounded. In this case, first of all, factors such as whether the contact is wet or damp should be considered.
Cause two: Poor contact
Sometimes the contacts around the steering wheel, due to frequent use, will wear out and cause virtual connection. At this time, the horn will be hoarse. If it encounters rainy weather and occurs with poor contact, it is likely to appear. The sound is low or not loud.
Reason three: the sound separator is soaked in water
Beimai Auto Parts Network reminds you: Although the crossover is inside the car, it should also be waterproof and moisture-proof. Once the terminal is found to be wet or even wetted by water, be sure to dry it in time and seal the door as soon as possible to prevent it. The phenomenon that the horn sound becomes low after the car rain again appears. [The speaker sound is low after the car rain ]
