[Rivera]

The size of the front door speaker of the Geely Vision is 6.5 inches, which is the same for both the 2018 and 2019 models. Function of car speakers: The speaker is the audio signal device of a car. During driving, the driver can emit necessary audio signals as required or regulated to warn pedestrians and alert other vehicles, ensuring traffic safety. It is also used for urging movement and transmitting signals. Working principle of car speakers: Car electric speakers produce sound through the vibration of a metal diaphragm. The car electric speaker consists of an iron core, magnetic coil, contacts, armature, diaphragm, etc. When the driver presses the horn switch, current passes through the contacts to the coil, generating magnetic force that attracts 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 plate. The contacts close again, allowing current to flow through the contacts to the coil, generating magnetic force and repeating the above action.
