Can the horn sound become louder again after it gets smaller due to water ingress?

[Jayden]

The horn sound can become louder again after it gets smaller due to water ingress. After water ingress, you can only try to repair it. You can use a hair dryer to heat the horn to evaporate the water inside. Once the water evaporates, the horn will recover. However, if the diaphragm of the horn itself is damaged due to water ingress, you can only replace it with a new one. The relevant introduction about car horns is as follows: Introduction 1: The horn is the audio signal device of the car. During the driving process, the driver can issue necessary audio signals as needed and according to regulations. Introduction 2: It warns pedestrians and attracts the attention of other vehicles to ensure traffic safety, and is also used to urge driving and transmit signals.
