A method of manufacturing a spiral electric horn

Abstract

The invention discloses a manufacturing method of a spiral electric horn, which comprises firstly preparing a loudspeaker tube, a diaphragm component, a liner, a chassis component, a tight ring and a cover plate component of the speaker tube, wherein the cover plate of the speaker tube is made of a composite The method is integrated with the reinforcement surface of the tight ring, so that the tight ring is embedded on the speaker cover plate as an insert to form the tight ring and speaker cover assembly; then the tight ring and speaker cover assembly are combined with Diaphragm components, liners and chassis components are riveted together to form a horn sub-assembly; finally, the horn sub-assembly and the loudspeaker are welded together by ultrasonic waves to form a spiral electric horn. The spiral electric horn prepared by the method of the present invention improves the boundary conditions of the diaphragm vibration system, improves the sound pressure level of the spiral electric horn and the consistency of the product, and greatly improves the sound transmission quality of the spiral horn. The service life is prolonged, and it has good social and economic benefits.

Description

technical field [0001] The invention relates to a manufacturing method of an automobile electric horn, in particular to a manufacturing method of a spiral electric horn. Background technique [0002] The traditional spiral electric horn structure, such as figure 1 As shown, it includes a speaker tube 1 , a speaker tube cover plate 2 , a tight ring 3 , a diaphragm assembly 4 , a liner 5 and a chassis assembly 6 . The manufacturing method is to first rivet the tight ring 3, the diaphragm assembly 4, the liner 5 and the chassis assembly 6 together to form a speaker sub-assembly, and then weld the speaker tube 1 and the speaker tube cover plate 2 together by ultrasonic waves , combined into a loudspeaker assembly, and finally press the horn sub-assembly into the loudspeaker assembly with a bayonet, which is coated with silicone rubber around it in advance, to form a car electric horn. Using such a manufacturing method, when the speaker sub-assembly is pressed into the speaker ...

AI Technical Summary

Problems solved by technology

Using such a manufacturing method, when the speaker sub-assembly is pressed into the speaker tube, it is easy to cause glue overflow and affect the appearance; when the speaker sub-assembly and the speaker component are assembled, the cooperation between the two is not easy to do Well, the quality cannot be guaranteed, resulting in poor boundary conditions of the diaphragm vibration system, which affects the improvement of the sound pressure level of the spiral electric horn
