1. Tone adjustment: When adjusting, attention should be paid to ensuring that the gap between the iron core and the armature is uniform, level, and not skewed. Otherwise, it is easy to collide with each other during operation, causing the horn to produce noise.

2. Volume adjustment: The volume of the speaker is related to the current passing through the speaker coil. The larger the current passing through, the louder the volume, and vice versa. Adjusting the contact pressure can change the volume. The adjustment of speaker volume and sound quality is interrelated, so it needs to be repeatedly adjusted to obtain the best sound.

Maintenance of horn:

(1) Regularly keep the appearance of the horn clean and ensure that all wiring is secure.

(2) Regularly check and tighten the fixing screws of the horn and bracket to ensure reliable grounding.

(3) The method of fixing the horn has a significant impact on its pronunciation. In order to ensure the normal sound of the horn, it cannot be rigidly installed, so it is fixed on a buffer bracket, that is, a sheet-like spring or rubber pad should be installed between the horn and the fixed bracket. 润色译文试试AI翻译笔记

(4) Regularly check the output voltage of the generator. High voltage can burn out the horn contacts, while low voltage (below the rated voltage of the horn) will cause the horn to produce abnormal sounds.

(5) When washing the car, do not rinse the horn directly with water to prevent water from entering the horn and causing it to not sound.

(6) When repairing the horn, attention should be paid to the position of each metal pad and insulation pad, and they should not be installed incorrectly.

(7) The continuous pronunciation of the horn should not exceed 10 seconds to avoid damaging the horn.
