Abstract
The utility model relates to a voltage-regulating and noise-reducing change-over switch of an automobile horn, which comprises a selection key and two contacts corresponding to the selection key, wherein one end of the selection key can be connected with the automobile horn and the other end can alternatively switch on a power source and forms an energizing circuit. The utility model is characterized in that each contact is connected with a resistor, the other ends of the two resistors are connected to one end of the power source after connected in parallel and the resistance values of the two resistors are respectively 1 ohm and 1.5 ohm. Voltage values which are loaded at both ends of the automobile horn can be changed by selecting proper resistance values and switching on the energizing circuit through the selection key, the voltage value is then lowered, the sound volume of the horn can be changed and the functions of voltage regulation and noise reduction are achieved. The utility model has the advantages of simple structure, convenient installation and operation and high reliability.
Description
Technical field
The utility model relates to the electronic installation that reduces the loudspeaker noise, specifically is meant a kind of pressure regulation noise reduction change over switch that is used on the car horn.
Background technology
Current, China's automobile industry development is very rapid.Automobile is lived, when work brings easily and fast, has also been produced many side effects to people.Wherein, automobile born noise has caused very big infringement to city dweller's physical and mental health.For this reason, horn-blowing control order in the urban district, the noise that restricting vehicle is blown a whistle and produced have been issued in some city.Though this measure has reduced automobile born noise, brought hidden danger to traffic safety, also increased inconvenience to the driver, the traffic accident that causes of can not blowing a whistle happens occasionally.
Summary of the invention
The purpose of this utility model provides a kind of change over switch that the multiple choices volume can be provided for the driver, after this kind switch has been adopted in expectation, the horn for vehicle noise is reduced to meets environmental protection standard, can guarantee driving safety again.
Described change over switch comprises that one one end can link to each other with car horn, the other end is the selection key of energized formation power circuit selectively, a plurality of contacts corresponding with this selection key, it is characterized in that: described contact has two, all be connected to a resistance on each contact, link to each other with an end of power supply after the other end parallel connection of two resistance.
Select suitable resistance value and connect power circuit, can change the magnitude of voltage that is added in the car horn two ends, this magnitude of voltage is reduced, can change the volume of loudspeaker, play the effect of pressure regulation noise reduction by selection key.The utlity model has the advantage that circuit structure is simple, enforcement convenience, good reliability are installed.
Description of drawings
Fig. 1 is the utility model circuit theory diagrams;
Fig. 2 is the contour structures schematic diagram.
Embodiment
R1 among Fig. 1, R2 are two resistance that are connected on the contact 1,3, contact 2 is unsettled, one end of selection key 4 links to each other with an end of car horn 5, the other end of car horn links to each other with an end of power supply 6, be connected on the other end of power supply after the other end parallel connection of resistance R 1, R2, press selection key 4, optional energising resistance R1 or R2, power supply, resistance, loudspeaker are connected formed the loop, loudspeaker are rung.Resistance value can be 1 Europe or 1.5 Europe, so can make the loudspeaker volume reduce to 1/2 or many or 1/4 of former volume, reaches the purpose of controlling noise.When selecting button to beat on contact 2, switch disconnects, and circuit is not worked.Label 7 among Fig. 2 is to select by the part shell.
The utility model can be reequiped on finished car, only needs during repacking that Fig. 2 is shown that change over switch is replaced and goes up former auto horn switch, shows by Fig. 1 that scheme links to each other the contact by lead with automobile storage battery and loudspeaker and promptly reequips successfully.
Claims (2)
1. car horn pressure regulation noise reduction change over switch, comprise that one one end can link to each other with car horn, the other end is the selection key of energized formation power circuit selectively, a plurality of contacts corresponding with this selection key, it is characterized in that: described contact has two, all be connected to a resistance on each contact, link to each other with an end of power supply after the other end parallel connection of two resistance.
2. car horn pressure regulation noise reduction change over switch as claimed in claim 1, it is characterized in that: the resistance of described two resistance is respectively 1 Europe and 1.5 Europe.
