Where is the rear door tweeter installed?

[DiCarter]

Rear door tweeters can be installed on the upper part of the door panel or on the A-pillar. Function of the horn: The horn is the audio signal device of a car. During driving, the driver can emit necessary audio signals as required and regulated to warn pedestrians and alert other vehicles, ensuring traffic safety. It is also used for urging movement and transmitting signals. Working principle of the horn: An automotive electric horn produces sound through the vibration of a metal diaphragm. When the horn button is pressed, current flows through the contacts to the coil, generating a magnetic force that pulls the armature down, forcing the diaphragm to move. The movement of the armature causes the contacts to open, interrupting the current and causing the coil's magnetic force to disappear. The diaphragm, along with the armature, returns to its original position due to its own elasticity and the spring plate, closing the contacts again and restoring the circuit. Current then flows through the contacts to the coil, generating magnetic force and repeating the above process. This cycle repeats continuously, causing the diaphragm to vibrate and produce sound.
