喇叭是汽车上的一种安全部件，可分为电震动式、气压震动式与电子喇叭等，按外形又可分为盆形、蜗牛形、筒形喇叭等。
Horn is a kind of safety components on the car, can be divided into electric shock type, pneumatic vibration and electronic horn, according to shape and can be divided into the shape of a basin, snail shaped, barrel shaped horn etc..
电震动式喇叭通过电磁作用推动金属膜片震动产生声音。这类喇叭便于调节音调，声音也较悦耳，广泛运用于汽车、拖拉机与摩托车。中小型汽车多使用体积小、重量轻、噪音低、指向性强的盆型喇叭。
Electric shock type horn through the electromagnetic effect to promote metal diaphragm vibrates to produce sound. This kind of horn is convenient to adjust the tone, sound is sweet, widely used in automobiles, tractors and motorcycles. Small and medium-sized cars with small volume, light weight, low noise, high directivity basin type speakers.
蜗牛喇叭最大特点是声音悦耳，多用于指向性要求不高的轿车上。
The biggest characteristic of snail horn is a pleasant voice, much to less demanding on the car.
气压震动式喇叭通过气流推动金属膜片发出声音，外形大多呈筒形，多用于气制动的大型车辆上。特点是声响高，指向性强，声音传播距离远，缺点是音质差、体积大。不过，近年来出现的蜗牛气压震动式喇叭占位缩小很多，音质也有了很大改善。
Pneumatic vibration horn through the airflow pushes the metal diaphragm sound, shape is cylindrical, used for large vehicle air brake. Characteristics of sound high, strong directivity, sound propagation distance, disadvantage is the poor sound quality, volume. However, the snail pressure in recent years is the emergence of vibration horn occupies a narrow lot, sound quality is also improved greatly.
电子喇叭通过电子音频放大电路推动扬声器发声，最大特点是声强、声调调整更加方便，音质也好。由于没有触点，不仅故障率低，使用寿命也长。
Electronic horn through the electronic audio amplification circuit driving the speaker sound, the biggest feature is more convenient and sound intensity, tone adjustment, good sound quality. Since there is no contact, not only the failure rate is low, long service life.
汽车该用哪种喇叭，国家没有具体规定，由生产厂家自己决定。不过，为了降低噪音污染，国家对于喇叭的声级有规定，其值在90—115分贝
What kind of car the horn, the country does not have specific provision, decided by the manufacturers themselves. However, in order to reduce the noise pollution, the country has stipulated the horn sound, its value in the 90 - 115 DB
