Description

Technical field: [0001] The invention relates to a motor vehicle horn, especially how the electronic module of a non-contact electronic horn adapts to the mechanical characteristics of the assembled horn and can still produce sound efficiently with the change of its own state and environment with the passage of time, and meets the performance and life indicators. Background technique: [0002] The traditional contact car horn, mainly because the life of its contacts is relatively short, many of them use electronic frequency stabilization to control the on-off of the contacts. There are many methods of frequency stabilization, such as based on RC oscillation, crystal, ceramics and integrated Circuits, single-chip microcomputers, etc., no matter which method is used, although the problem of contact life is solved, the following problems are still difficult to solve: [0003] 1. The manufacturing process is complicated. [0004] It is necessary to match the frequency parameter...

AI Technical Summary

Problems solved by technology

Because of the relationship between the mechanical manufacturing process of the speaker itself, the overall natural vibration frequency of the speaker is distributed within a certain range, so that the frequency stabilization frequency of the circuit is different from the mechanical natural vibration frequency, thus affecting the sound level of its sound.

[0005] 2. Due to the influence of ambient temperature and other short-term or long-term mechanical effects, the natural vibration frequency has shifted, resulting in frequency mismatch and sound level change, which cannot be solved at present

[0006] 3. The electronic circuit itself determines that the parameters of the device that controls the frequency are affected by temperature, etc., resulting in frequency mismatch and sound level changes. At present, it is solved by improving the stability of the device, and the cost is high.

[0007] 4. Due to the long-term use against the natural characteristics, the life of the diaphragm is reduced

[0008] 5. The above problems actually also exist in another control parameter - the electrification rate
