What can I do to make a car horn sound when the car is locked?

If you can lock the car, you need to keep pressing the lock button, and the horn of the car will sound three times.

Speaker: A horn is an audio signal device for a car. In the process of driving, the driver sends the necessary sound signals according to the needs and regulations to warn pedestrians and attract the attention of other vehicles, ensure traffic safety, and is also used to urge and transmit signals.

How it works: When the horn button on the steering wheel or other position is pressed, the current from the battery will flow through the loop to the solenoid coil of the horn relay, and the solenoid coil will attract the moving contact of the relay to close and close, and the current will flow to the horn. The current causes the electromagnet inside the horn to work, causing the diaphragm to vibrate and produce sound.

Classification: Horns are divided into electric horns and air horns according to their pronunciation power; According to the shape, it is divided into three categories: spiral, cylindrical and basin; According to the sound frequency, it can be divided into tweeter and woofer; According to the wiring method, it can be divided into single-wire and double-wire speakers; According to the presence or absence of contacts, it can be divided into contact type (ordinary type) electric horn and contactless type (electronic) electric horn. Among them, the air horn is mainly used in heavy-duty trucks with air brake devices, and the electric horn has the characteristics of simple structure, small size, light weight, pleasant sound and convenient maintenance, so it has been widely used in small and medium-sized vehicles.

Maintenance: Always keep the appearance of the speaker clean, and the wiring should be reliable.

The fixation method of the horn has a great influence on its pronunciation. In order to make the sound of the horn normal, the horn can not be rigidly installed, so it is fixed on the buffer bracket, that is, a sheet spring or rubber pad should be installed between the horn and the fixed bracket.

Always check the generator output voltage. If the voltage is too high, the horn contacts 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.

You can use the remote control key to open the lock horn and press the unlock and lock buttons at the same time for 3 seconds.
