产品说明:

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。

  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。

  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。

  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。

  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。
