Car hornThey are divided into electric and air horns, working in different ways. The electrophones cause membranes to vibrate through constant electrical circuits and blackouts, while the air horns use compressed air currents to make membranes vibrate. The electric horn is widely used in small and medium-sized vehicles because of its simple structure and ease of repair; air horns are used mostly for heavy trucks equipped with gas brakes. They rely on different power sources to drive film vibrations, thus providing a warning sound for vehicles。
Let's start with the specific work process of the horn. The horns usually consist of components such as iron cores, magnetic wires, contact points, electrical hubs and film. When the driver pressed the horn switch, it was like a wonderful physical trip. At that point, the current was like a soldier who had been given instructions to run through the wire through the contacts. The coil, which acts as an electric current, produces a powerful magnetic force, which is like an invisible but powerful hand, suffocates the power hub and forces the diaphragm to move。
However, the power grid movement triggered a series of chain reactions. In the moment when the power hub moves, the contact points are disconnected and the currents are interrupted, like rivers that are suddenly cut off. The magnetism of the coil quickly disappeared as the current was cut. However, the story is not over. The diaphragm returns to its original position, with its own elasticity and the support of springs, as a gentle dancer. At this moment, the contact points are closed again, the circuits are indirectly connected at the second time, and the currents are re-emerged through the contacts through the loop, and the magnetic forces re-emergence so that the metallic film continues to vibrate and the sound is generated。
The electrophones are also structured into columns, spirals and basins. Spiral horns with their own unique loudspeaker, which convected into a spiral, which not only skilfully compressed sizes, but also allowed sound to grow back and forth through resonance boards and loudspeakers. Although there are no speakers, they are flat, small, light and easy to install, and sound resonates with a resonance panel, and they have a very wide range of uses, albeit of a slightly inferior sound。
And look at the horn. The air horns work on the air compressor because it has to work on compressed air currents. When the air horns work, a strong air current formed by compressed air strikes the metal membrane, as if a storm had passed, causing it to vibrate sharply and make a sound. Owing to their large voice, they are often used in larger and medium-sized trucks and buses that require stronger warning effects, although in urban areas the use of air horns is usually prohibited, taking into account such factors as noise。
Car horns are small, but they contain fine physical principles and engineering. The electric and air horns play an important role in their respective vehicle types through different modes of work, providing strong voice alerts for road traffic safety and ensuring that vehicles are brought to the attention of others in a timely manner and reduce potential hazards。
