1, the circuit set up: the use of high-quality electronic components and integrated protection circuitry

2, environmental protection: the use of high quality ABS plastic outer body, install handle using surge painting

3, super power: operating current of 200 mA, saving battery power

4, low-voltage operation: 12V horn work properly 5V, 36-72V 30V horn work properly

5, super waterproof: fully sealed package watertight

6, sound pleasant: 105Bb (dB) is not harsh, especially for small and elderly type models

7, long-lasting quality: Long-term use of sound constant

8, the protection function: long-term power 10 seconds to lock automatically stop Naruto, re-energized as usual

9, long life: 300,000 times normal test

10, the anti-interference: without affecting other electrical use

First, the electrical horn Overview

1, electric horn pronunciation of electromagnetic resonance principle, double (single chassis ground), closed-end short-time working, mechanical intermittent oscillation.

2, electric horn work status of short-term fixed duty, continuous load time is not more than three seconds, a continuous beep 30 seconds parts destructive test scrapped.

3, the relevant references, enterprise standard Q/XDJL01-1997, Japanese Industrial Standard JIS & nbsp; D5701-1977 & nbsp; Industry Standard QC/T30-2003, professional standards ZB/T35001-87 & nbsp; GB GB-15742-2001 <./p>

4, at the obvious place identification current, voltage, the fundamental frequency, the sound pressure.

& nbsp; Second, electric horn works

& nbsp; Third, the basic structure and composition of horn key parts

Fourth, the speaker common faults and reason

1, the user using the speaker does not ring for some time. Reason: Some internal next spring, pronounce plate stress, contact wear, the current decline.

2, the user some time speakers sound bad. Reason: Some internal next spring, pronounce plate stress, fundamental frequency, current rise.

& nbsp;

speaker longevity understanding: according to the national standard (GB15742-2001) "3.1.3.1 power is not used for motorcycle 7kw small speakers 10000 times .3.1.3.2 for use M, N class car and more than 7kw large horn motorcycle horn is 50,000 times .3.2.7.2 durability test to tweet one second, 4 seconds of rest cycle. If the trials half, before the sound level and the test has changed, allowing the speaker to adjust once at the end of the test, in case of the need to allow adjustment again. " That small speakers for less than the allowable adjustment 7kw of 5000, for more than 7kw big horn allowable adjustments 25,000 times. But electric horn in actual use in order to make it possible for users to give way or avoidance crowd continuous long honk when other obstacles, beyond the Ming 1 second pause 4 seconds range, electric shock or severe erosion wear spring sheet, plate stress occurs pronunciation After the change of speakers do not sound or poor sound quality, its life is affected, it is possible to extend the life by the second adjustment.
