The reason why the horn does not sound when the steering wheel is straightened but sounds when turning is due to poor contact of the horn contacts under the steering wheel; it may also be caused by a short circuit or malfunction inside the horn switch. Below is relevant information about car horns: 1. Introduction: The horn is the audio signal device of a car. During driving, the driver can emit necessary audio signals as needed or required to warn pedestrians and attract the attention of other vehicles, ensuring traffic safety. It is also used for urging movement and transmitting signals. 2. Working principle: The car electric horn produces sound through the vibration of a metal diaphragm. The car electric horn consists of an iron core, magnetic coil, contacts, armature, diaphragm, etc. When the driver presses the horn switch, current flows through the contacts to the coil, generating magnetic force that attracts the armature, forcing the diaphragm to move. The movement of the armature disconnects the contacts, interrupting the current and causing the magnetic force of the coil to disappear. The diaphragm, along with the armature, returns to its original position under its own elasticity and the action of the spring plate. The contacts close again, allowing current to flow through the contacts to the coil, generating magnetic force and repeating the above action. This cycle continues, causing the diaphragm to vibrate repeatedly and produce sound.
