What Are the Reasons for a Car Horn's Sound Becoming Quieter?
1 Answers
There are several reasons why a car horn's sound may become quieter, including electromagnetic interference, broken wires or damaged paper cone in the horn, short circuit in the horn output, damage to the power amplifier module, and reduced contact gap in the diaphragm. Below are detailed explanations and solutions: Electromagnetic Interference: Various electrical devices, whether connected to the computer or not, can cause electromagnetic interference, resulting in a very low sound, though not completely silent. The volume may also become unstable, returning to normal or becoming louder once the interference weakens. Solution: Replug the speaker connector. Broken Wires or Damaged Paper Cone in the Horn: The horn's silk wire or paper cone primarily amplifies the sound. If the silk wire breaks or the paper cone is damaged, the horn's sound will become quieter. Solution: Replace the broken silk wire or paper cone. Short Circuit in the Horn Output: This can cause a short circuit in the car audio power amplifier, leading to output saturation and a quieter sound. Solution: Replace the horn circuit. Changed Diaphragm Contact Gap: A reduced contact gap in the diaphragm increases resistance and decreases current, resulting in a quieter horn sound. Solution: Adjust the small screw for the contact gap on the horn to restore normal sound.
