Dear friends,

I want to know about the working of electric horn in two wheelers.

If they are working in DC supply, then how the coil in the horn are vibrates to create sound?

Please help me with the ANSWER.

THANK YOU!!

To produce a sound when the horn is pressed, an electromagnet is used to cause a steel diaphragm to move. As the current is applied to the electromagnet, the diaphragm moves toward the magnet. When the diaphragm moves toward the magnet, a connection is released, temporarily disconnecting the current and allowing the steel to relax. Once this happens, the electromagnet reapplies current, again moving the diaphragm toward the magnet. This cycle repeats evenly and causes the diaphragm to oscillate back and forth producing the sound of the car horn.
