car horn

The car horn is the audio signal device of the car. In the driving process of the car, the driver sends out the necessary audio signals according to needs and regulations to warn pedestrians and attract other vehicles' attention to ensure traffic safety. At the same time, it is also used for urging and transmitting signals.

The car electric horn produces sound by the vibration of the metal diaphragm. Automobile electric horn is composed of iron core, magnetic coil, contact, armature, diaphragm and so on. When the driver presses the horn switch, the current passes through the coil through the contact, and the coil generates magnetic force to attract the armature, forcing the diaphragm to move, and the armature moves to disconnect the contact, the current is interrupted, the magnetic force of the coil disappears, and the diaphragm is elastic and spring sheet Under the action, it returns to the original position together with the armature, the contact closure circuit is connected again, and the current flows through the contact through the coil to generate magnetic force, and the above action is repeated. In this way, the diaphragm keeps vibrating and generates sound. The car electric horn produces sound by the vibration of the metal diaphragm.

The car horn generates sound through the vibration of the metal diaphragm. The car horn is composed of iron core, electromagnetic coil, contact, armature, diaphragm, etc. When the driver presses the horn switch, current flows through the coil through the contacts, and the coil generates magnetic force to attract the armature, thereby forcing the diaphragm to move. The armature moves to open the contacts, the current is interrupted, and the magnetic force of the coil disappears. The diaphragm is elastic and spring. Under this action, it returns to the original position together with the armature, the contact closure circuit is connected again, the current flows through the coil through the contact to generate magnetic force, and the above action is repeated. In this way, the diaphragm keeps vibrating and produces sound. The sound board is rigidly connected to the diaphragm, which can make the vibration stable and make the sound more pleasing (ie the principle of electromagnet)

According to the sound power, car horns are divided into two types: air horn and electric horn; according to their appearance, they are divided into three types: cylindrical, spiral and basin; according to the sound frequency, they are divided into two types: tweeter and woofer.
