Can the car audio suddenly lose sound and recover by itself?

The car audio suddenly losing sound cannot recover by itself. If only one speaker has no sound, it may be a speaker problem or a fault in the speaker wiring. If all four speakers are not working, first check if the volume is turned on. If the volume is on but there is still no sound, it is necessary to specifically check the internal hardware issues of the navigation head unit, or it could be that the sound module is damaged. More details about the car electric horn are as follows: 1. Introduction One: The car electric horn produces sound through the vibration of a metal diaphragm. The car electric horn consists of an iron core, magnetic coil, contacts, armature, diaphragm, etc. When the driver presses the horn switch, current flows through the contacts and the coil, generating magnetic force that pulls the armature, forcing the diaphragm to move. The movement of the armature disconnects the contacts, interrupting the current and causing the magnetic force of the coil to disappear. The diaphragm, along with the armature, returns to its original position under its own elasticity and the action of the spring. 2. Introduction Two: The contacts close the circuit again, allowing current to flow through the contacts and the coil, generating magnetic force and repeating the above actions. This cycle repeats continuously, causing the diaphragm to vibrate and produce sound. The resonance plate is rigidly connected to the diaphragm, making the vibration smooth and the sound more pleasant. The working principle of the air horn is to use the airflow of compressed air to vibrate the metal diaphragm and produce sound. Therefore, it can only be used on cars equipped with an air compressor.
