This problem can be analyzed in two aspects: one is the horn on the car steering wheel, and the other is the horn of the car audio in the car.

If it is the horn on the steering wheel of a car, it is usually located inside the bumper of the front wheel. If you want to see it, you have to remove the front bumper to see it.

When honking the horn while driving, do the following to extend the life of the horn:

1. When honking the horn, do not press it too hard, let alone use brute force. .

2. When driving, try to avoid honking the horn for a long time.

3. Be careful not to allow water to enter the speaker.

If it is a car audio speaker in the car, it is usually near the triangular window of the A-pillar or on the C-pillar. There is no standard, consistent answer to this question because the number of horns varies between different models.

General models have only four speakers, while high-end models have more than 8 speakers. If it is a model with 8 speakers, they are generally located in the following locations:

There will be 2 speakers on the instrument panel and on the platform under the windshield; one on each of the left and right front doors, and 2 speakers; There is one rear door on the left and right, 2 in total; there is one C-pillar on the left and right, 2 in total.

The more speakers a stereo has, the better and more shocking the music will be. Of course, the price of the vehicle will be more expensive.

Working principle

Car electric horns rely on the vibration of a metal diaphragm to produce sound. The car electric horn is composed of iron core, magnetic coil, contacts, armature, diaphragm, etc. When the driver presses the horn switch, current passes through the coil through the contacts, and the coil generates magnetic force to attract the armature, forcing the diaphragm to move. The movement of the armature causes the contacts to open, the current is interrupted, and the coil's magnetic force disappears.

The diaphragm returns to its original position together with the armature under the action of its own elasticity and the spring leaf. The contact is closed and the circuit is connected again. The current flows through the contact through the coil to generate magnetic force, and the above action is repeated. This repeated cycle causes the diaphragm to vibrate continuously, thereby emitting sound. ***The sound board and the diaphragm are rigidly connected, which can make the vibration smooth and produce a more pleasant sound (that is, the electromagnet principle).
