Description

Technical Field

[0001] The utility model relates to the technical field of automotive speakers, and specifically relates to an automotive speaker cover. Background Technique

[0002] The horn is an audio signal device of the vehicle. During the driving of the vehicle, the driver emits necessary audio signals according to needs and regulations to warn pedestrians and attract the attention of other vehicles, ensuring traffic safety. At the same time, it is also used for urging and transmitting signals. The automotive electric horn emits sound by the vibration of the metal diaphragm. The automotive electric horn consists of an iron core, a magnetic coil, a contact, an armature, a diaphragm, etc. When the driver presses the horn switch, the current passes through the contact and through the coil. The coil generates magnetic force to pull down the armature, forcing the diaphragm to move. The movement of the armature disconnects the contact, interrupting the current, and the magnetic force of the coil disappears. The diaphragm, together with the armature, returns to its original position under its own elasticity and the action of the spring piece. The contact closes and the circuit is connected again. The current passes through the contact and through the coil to generate magnetic force, repeating the above actions. In this way, the diaphragm vibrates continuously, thus emitting sound. The resonance plate is rigidly connected to the diaphragm, which can make the vibration smooth and the emitted sound more pleasant.

[0003] However, it still has some disadvantages. For example, when installing the automotive speaker, due to the small gap of the car door, it is not very convenient to fix the automotive speaker during installation, and a protective cover is also required at the front speaker opening of the automotive speaker to protect it, so as to increase the service life of the automotive speaker.
