speaker is a kind of safety component on the car. It can be divided into electric shock, pneumatic shock and electronic speaker, and can be divided into basin-shaped, snail-shaped, cylindrical speaker, etc. according to the shape.

   Electric shock loudspeaker drives the metal diaphragm through electromagnetic action to generate sound. This type of speaker is easy to adjust the tone and the sound is pleasant. It is widely used in cars, tractor and motorcycle. Small and medium-sized cars usually use Basin-type speaker with small volume, light weight, low noise and strong orientation.

   The biggest feature of snail horn is that the sound is pleasant, which is often used in cars with low directional requirements.

   Pneumatic vibrating speaker pushes metal diaphragm through air flow to make sound. Most of the shapes are cylindrical and are mostly used in large vehicles with air braking. Features are high sound quality, strong direction, and long sound transmission distance. The disadvantages are poor sound quality and large volume. However, in recent years, the space occupied by snail air pressure vibrating speakers has been much reduced, and the sound quality has also been greatly improved.

   The electronic speaker pushes the speaker to sound through the electronic audio frequency amplifier. The biggest feature is that the sound intensity, the tone adjustment is more convenient, and the sound quality is good. Because there is no contact, not only the failure rate is low, but also the service life is long.
