A Brief Introduction of the Disc Horn
2023-07-13
The disc horn is the most common horn. Because it is shaped like a basin/disc, so it is called “disc horn”. The disc horn is relatively cheap, mostly used in cars of Japanese and Korean models. And the sound of the disc horn is crisp.
Working Principle:
The electromagnet adopts a solenoid structure. The core is surrounded by an exciting coil, and the air gap between the upper and lower cores is in the middle of the coil, producing a large suction force. And then the upper core is sucked down and hits the lower core, producing a lower basic frequency, stimulating the diaphragm and resonating with the sounding board bonded to the diaphragm.Features:
The diaphragm resonates with the sounding board bonded to the diaphragm, thus the disc horn can emit a sound with a much stronger frequency and a more concentrated distribution. In order to protect the contacts, some disc horns are also connected with arc extinguishing capacitors between the contacts.Signal Generation Mode:
The disc horn is mainly composed of two parts: electric air pump and air horn. When the horn button is pressed, the DC motor air pump runs and produces compressed air; Compressed air passes directly into the air horn to make the horn sound.Previous:Why is a Horn Called “Snail Horn”
