Variable resistance with insulated section is installed in the cavity of speaker external board. A flute is on the down part of the speaker button. And power supply contact is set on the inside of flute. Loop is formed by variable resistance, speaker, location metal sleeve, and power supply contact. The invention could control the output power of speaker according different situation by driver and decrease safety hidden troubles.

Description

A kind of car horn

Technical field

The present invention relates to a kind of car horn.

Background technology

Each big city is for beautifying the environment now, reduce noise pollution and released automobile city limit ring relevant laws and regulations successively, make the use of car horn be subjected to certain restriction, but car horn is as a kind of indispensable emergent active safety measure of automobile, many times can in time remind pedestrian and vehicle, thus the generation that avoids traffic accident.

Present auto vendor has generally adopted the output of high strength sound equipment, and has only set a kind of intensity for guaranteeing the warning function of loudspeaker, and promptly loudspeaker have only a kind of volume.Can not as scaring passerby, animal etc., bring beyond thought serious consequence sometimes according to driving situation control loudspeaker volume owing to use.

Fortunately, the problems referred to above are recognized for those skilled in the art, and designed the car horn that to adjust volume, but similar techniques has mostly adopted electronic component to add masterplate and has controlled the adjusting that realizes volume, there is complex structure, is difficult to control, maintain difficult problem, make to be difficult to be widely used on the economic vehicle.

Summary of the invention

The objective of the invention is to problem at the prior art existence, a kind of car horn is provided, adopts simple physical construction, realize the adjustable of car horn sound output intensity, make the driver control output power of speaker, thereby reduce potential safety hazard according to different situations oneself.

A kind of car horn includes horn button, power contact, retracing spring, location metal sleeve, button positioning ring, loudspeaker, loudspeaker exterior panel and power supply lead wire.Wherein the loudspeaker exterior panel is installed in the groove of bearing circle, and retracing spring is contained in loudspeaker exterior panel inner chamber bottom, and horn button is installed on top, and is upwards withstood by retracing spring, horn button outward again the installing and locating metal sleeve position.The improvement of this patent is: at loudspeaker exterior panel inner chamber variable resistor is installed, the variable resistor top is fixed with insulated part, and integral body is column structure, is positioned at the below of horn button.The horn button bottom has and above-mentioned column structure corresponding grooves, when horn button is moved down, column structure can move in groove, power contact is arranged on the madial wall of groove, when horn button was subjected to the retracing spring effect to be in vertex position, power contact just in time contacted with the insulated part at variable resistor top.Variable resistor draws power supply lead wire and loudspeaker, location metal sleeve and power contact connect into the loop.

The present invention because of resistance has adjustability, along with the depth of pressing under the horn button realizes the adjusting of electric current, thereby reaches the effect of regulating the speaker sound signal intensity by increased a trimmable resistance horn switch on orthodox car loudspeaker parts.When honking downwards, power contact is by the downward slippage in variable resistor top, and the electric current that loudspeaker obtain also increases from small to large gradually, and voice signal strengthens gradually.Like this, human pilot just can be controlled the size of loudspeaker volume, adjustable car horn device according to actual conditions.

The present invention not only has the basic function of orthodox car loudspeaker, has more increased the intensity scalable function of hommization, makes its requirement that more can satisfy the urban safety rules, and to solving the city automobile noise pollution of blowing a whistle, reducing potential safety hazard has positive role.Simultaneously,, can directly carry out a little change to present car horn button for guaranteeing the low cost of this device, the variable resistor of promptly in bearing circle, directly packing into below the button, simple in structure, the reliability height is realized easily.

Embodiment

Describe structure of the present invention in detail below in conjunction with accompanying drawing:

Referring to Fig. 1 and Fig. 2, the basic structural components of this car horn has variable resistor 1, horn button 2, insulated part 3, power contact 4, retracing spring 5, location metal sleeve 6, button positioning ring 7, loudspeaker 8, loudspeaker exterior panel 9 and power supply lead wire 10.Loudspeaker exterior panel 9 is installed in the groove of bearing circle, and retracing spring 5 is installed in loudspeaker exterior panel 9 inner chamber bottoms, and horn button 2 is installed on top, and retracing spring 5 upwards withstands horn button 2, and horn button 2 outer installing and locating metal sleeves 6 again position.At loudspeaker exterior panel 9 inner chambers one variable resistor 1 is installed also, variable resistor 1 top fixed insulation part 3 forms an integral body, is column structure, is positioned at the below of horn button 2.Horn button 2 bottoms have and above-mentioned column structure corresponding grooves, cover on column structure, power contact 4 is installed on the madial wall of groove, when horn button 2 is subjected to the retracing spring effect to be in vertex position, power contact 4 just in time contacts with the insulated part 3 at variable resistor 1 top, power contact 4 is connected by power lead with location metal sleeve 6, and variable resistor 1 draws power supply lead wire 10 and loudspeaker, locate metal sleeve 6 and power contact 4 connects into the loop.

Principle of work is as follows:

When horn button 2 is in position shown in Figure 1, power contact 4 contact insulated parts 3, this moment, loudspeaker were in off working state, and loudspeaker do not have sound output.

When the user presses horn button 2, the user is firmly big or small according to actual conditions control, under the effect of retracing spring, it is also just different that button moves down the depth, at this moment power contact 4 is with variable resistor 1 contact, electric current, flows through each electric elements such as location metal sleeve 6, loudspeaker and forms the loop through power contact 4 by variable resistor 1 by power supply lead wire 10.

When power contact 4 contacts the state that is in as shown in Figure 3 with adjustable resistance 1, the resistance maximum, the electric current minimum that car horn obtains, to send the sound minimum for loudspeaker under this state.

The degree of depth difference that moves down along with button, variation is freeed in the position of power contact 4 contact variable resistors 1 thereupon, when button 2 moves down into Fig. 2 and state shown in Figure 4, the resistance minimum, just maximum by the electric current of loudspeaker like this, at this moment loudspeaker are in the peak power output state, when the user unclamps horn button, horn button is homing under the effect of retracing spring, the flow process of finishing the work.
