a snail horn

Abstract

The invention discloses a snail horn. The snail horn disclosed by the invention has the advantages that a detection circuit, a circuit board and a control switch are arranged in the snail horn, so that when water enters the snail horn but does not influence the sound production of a sound production device, whether the water enters the snail horn or not can be detected by the detection circuit which is mounted in the snail horn; a water inlet signal is output by the detection circuit to the circuit board, the water inlet signal is received by the circuit board, an intermittent signal is outputto the control switch, a sound production signal is converted into a pulse signal, then the pulse signal is output to the sound production device, and further the sound production device is controlled to realize intermittent sound production for reminding a user that the water enters the snail horn. An existing snail horn is easily short-circuited when the water enters the snail horn, so that a potential safety hazard exists; and by replacing the existing snail horn, the condition that the safety of the whole vehicle is influenced by short circuiting of the snail horn is avoided, and danger is avoided.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to a snail horn. Background technique [0002] The snail horn is to add a snail-shaped acoustic cavity to the ordinary horn. Improve sound quality and boost volume. The snail horn is a pair of car horns. Because it looks like a snail, it is called a snail horn to distinguish it from a basin horn. It is actually called a "treble and bass horn". The snail horn is mostly used to warn drivers who are approaching quickly, and its warning sound can allow the other driver to estimate the distance and direction of the vehicle that issued the warning sound. [0003] Existing snail horns cannot detect whether water has entered the interior, and water entering the snail horn may easily lead to the problem that the sound volume of the horn is too low. In the traffic law, there are the following regulations on the use of car horns: Motor vehicles should slow down and honk when approaching ...

AI Technical Summary

Problems solved by technology

Cars equipped with a snail horn with reduced sound volume have the following potential safety hazards during driving: it is difficult for the other driver to hear the volume reduction warning sound when the window is closed in the car, or the warning sound is wrongly judged based on the warning sound heard The distance between the vehicles, our driver defaults that the other driver has heard the warning sound after pressing the snail horn to sound the warning sound. In such a situation, when the cars on both sides drive to a sharp turn, the road section at the top of the slope that affects the safe sight distance, and overtaking Or in an emergency, it is very prone to major traffic accidents

[0004] At the same time, when water enters the interior and the volume of the snail speaker does not decrease, the user cannot find the water entering the interior of the snail speaker. At this time, the use of the snail speaker is prone to short circuit phenomenon, and there is a safety hazard in the use of the snail speaker, which will affect the safety of the vehicle and is prone to safety problems.
