Inverted magnetic circuit ultra-thin structure automobile horn

Abstract

An inverted magnetic circuit ultra-thin car horn includes a frame, a spider, a diaphragm, a voice coil, a suspension system, and a magnetic circuit system. The magnetic circuit system includes a main magnet, a secondary magnet, a U-shaped iron, a washer, and a bullet-shaped head. The magnetic circuit system is inverted and installed above the suspension system, and is fixed by screws. The frame is made of die-cast aluminum and supports the suspension system and the magnetic circuit system. The suspension system includes a spider, a diaphragm, and a voice coil, and the voice coil is spaced with the magnetic circuit system to drive sound production. The installation depth of the horn is less than 43mm. This utility model has a novel structure and ingenious design. By installing the magnetic circuit system above the suspension system with an inverted magnetic circuit structure, it breaks through the traditional height limitation of "suspension system + magnetic circuit system" for horns, meeting the needs of scenarios with strict requirements for installation depth, such as ceiling speakers, wall speakers, and car audio systems.
