Can a stall loudspeaker be connected to a car battery? Introduction to the loudspeaker: The loudspeaker is the audio signal device of a car. During the driving process, the driver issues necessary audio signals as needed and according to regulations to warn pedestrians and attract the attention of other vehicles, ensuring traffic safety. It is also used to urge movement and transmit signals. How the loudspeaker works: The car horn produces sound through the vibration of a metal diaphragm. When the driver presses the horn switch, current flows through the contacts to the coil, generating magnetic force that pulls down the armature, forcing the diaphragm to move. The movement of the armature opens the contacts, interrupting the current and causing the coil's magnetic force 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, completing the circuit, and current flows through the contacts to the coil, generating magnetic force and repeating the above process. This cycle continues, causing the diaphragm to vibrate continuously and produce sound. The resonance plate is rigidly connected to the diaphragm, making the vibration smooth and the sound more pleasant.
