(1) Always keep the surface of the speaker clean, and the wiring should be firm.
(2) Regularly check and fasten the fixing screws of the horn and the bracket to ensure reliable grounding.
(3) The fixing method of the horn has a great influence on its pronunciation. In order to make the sound of the speaker normal, the speaker cannot be rigidly installed, so it is fixed on the buffer bracket, that is, a leaf spring or rubber pad should be installed between the speaker and the fixed bracket.
(4) Always check the generator output voltage. If the voltage is too high, the contacts of the horn will be burned out, and if the voltage is too low (lower than the rated voltage of the horn), the horn will make an abnormal sound.
(5) When washing the car, do not wash the horn directly with water, so as to avoid water entering the horn and making the horn not sound.
(6) When overhauling the horn, pay attention to the positions of the metal pads and insulating pads, and do not install them wrongly.
(7) The continuous sound of the speaker shall not exceed 10s, so as not to damage the speaker.
(8) Do not put all kinds of foreign objects into the speaker to avoid abnormal sound.
