Vehicle sound signals are used to notify pedestrians and drivers of the approach of a vehicle or the condition of its operating units. The sound signal is also included in the “car guard” system or car anti-theft system.
Based on the nature of their sound, signals are divided into noise and tonal, and based on their design - into horn and hornless. Noise signals are hornless, tonal signals are hornless.
The signals are powered with direct current from the vehicle network.
The operating principle of noise and tone signals is similar. Their main executive element is an electromagnet, the coil of which is connected to the power supply through the breaker contacts. The electromagnet armature is connected to a sound-emitting membrane.
When current flows through the coil of an electromagnet, its armature is attracted to the core, and the membrane bends. At the same time, the breaker contacts open, the electromagnet coil is de-energized, and the armature, under the action of the elastic force of the membrane, returns to its original position, closing the breaker contacts. Thus, the process of attracting and releasing the armature becomes periodic, and oscillations of the armature occur along with the membrane. The pitch of the emitted sound depends on the frequency of armature oscillations. Based on the fundamental frequency of sound, signals are divided into high- and low-tone signals.
On cars, parallel connection of high and low tone signals is used. The fundamental sound frequencies of these signals are harmoniously combined. Typically, the difference between the fundamental frequencies of high and low tone signals is 65-100 Hz.
Vehicle sound signals are characterized by the sound pressure level (in decibels) and the spectral composition of the sound. Signals whose frequency spectrum is in the range of 1800-3550 Hz best cover traffic noise and are heard in the cabin of an overtaken vehicle. Therefore, the dimensions, materials and configuration of the membrane, resonators and other sound-emitting parts of the signal are selected in such a way that all its sound energy is concentrated in this range.

Table 1 shows the main parameters of some types of vehicle sound signals.
To eliminate the influence of the vehicle's mass on the sound emission of the signal, its spring suspension is used.
The vortex movement of air that occurs when the car moves changes the audibility of the signal. The higher the vehicle speed, the shorter the distance at which the signal is heard.
How to output a signal to a separate button
A horn or horn is a safety element that should be functional in any car. Thanks to this device, accidents can be prevented, which is why its performance is very important. What to do if the horn does not work, and how to connect the signal after repair? You will find answers to these questions below.
Electronic signals
The main part of electronic beeps is a chip that generates a sound of the desired frequency and transmits it to the device’s loudspeaker. The signal volume can reach 110 dB, and the frequency range is very wide and can be completely different in each individual model.
Electronic horn
They can be installed on almost any car, regardless of the dimensions and voltage of the electrical circuit. Electronic horns can operate on both 12 and 24 V. The device can reproduce both single-tone sounds and various melodies.
It is worth remembering that a musical horn can cause unwanted attention from traffic police officers if the melody resembles a special signal. In this case, a fine may be imposed on the driver.
How does a car horn work?
Let's consider a universal diagram of a car sound signal:
In accordance with the connection diagram, when the driver presses the control button, a current begins to pass through the winding, which ultimately magnetizes the core, which in turn attracts the armature. With this anchor, the rod that bends the membrane begins to move, and thanks to the nut, the contacts open, which helps interrupt the electrical circuit. All elements, in particular the disk, rod, anchor and others, return to their original position using a spring and membrane. In this case, the contacts close, which again leads to the passage of current through the winding. The process of opening the contacts is carried out by pressing the horn button on the steering wheel (the author of the video is the channel pribambas sender).
Do-it-yourself signal diagnostics and repair
Checking with repairs is performed as follows:

How to remove the backlight mode, day and night, or display it on a separate button (in Japanese)
Answer:
You need pin 8, that's where the lighting control signal is. Of course, before cutting, call him, because... For obvious reasons I can’t check. Look at the color - otherwise I often end up with an inverted block according to the pattern. On RHD it is Y/R - yellow with a red stripe. Scheme:
Pinout of the M61 block (you just need it).
Here is the description of pin 8.
Yes, and more. It is possible that some functions may be disabled that are tied to this signal. I won’t say which ones. Check everything when you cut it.
Solution:
Hooray! It's finished. I found a wire that activates the night mode. I connected it to a separate switch and that’s it. Now it turns on at will (automatic or manual). The wire is located on the block going to the DVD, yellow with a red stripe.

Fixing a faulty car horn
The most common malfunction is contact oxidation. In some cases, the latter fall out or move away. In situations where the emitter does not work, start your inspection with the condition of the wiring.
Before working with electricity, be sure to remove the terminals from the battery! Disconnect and discharge the capacitor that controls the airbag. Its contacts are most often located under the steering column.
The three contacts are usually located near the hub, protected by plastic. Clean them with a file and firmly fix them in their original position. Here you may need the help of a friend to remove the casing.

Malfunctions of the sound signal of the VAZ 2107
There are three types of malfunctions of the VAZ 2107 sound signal:
Weak or unnatural signal sound
Over time, the alarm sound may become quiet, hoarse, or intermittent. The reason for this is usually a malfunction of the electrical element or poor contact at its terminals. Dirt and water may get inside the sound element. As a result, the mechanism becomes corroded, and the membrane begins to move with difficulty or becomes completely jammed. The signal coil winding may also fail, but this happens quite rarely.
For diagnostics, the ES is connected directly to the battery. To do this, use additional wires or remove the electronics. If the result is the same, the sound element is faulty. Since it is not dismountable, it is impossible to clean it. You can try to move the membrane by rotating the adjusting screw.
There have been cases when “shock therapy,” so to speak, helped restore the signal. A jammed membrane can be loosened by thoroughly tapping the signal with the handle of a screwdriver. Better yet, remove the signal from the car and knock it on a wooden surface. You can also try blowing it out with compressed air. The membrane can be released and the signal will continue to function. This is worth doing in the case when there is nothing left but to buy a new signal.
Adjusting and replacing the sound signal
You can adjust the signal without dismantling it. This is done as follows:
By rotating the adjusting screw, the loudest and clearest signal sound is achieved.
The second ES is regulated in the same way, having first turned off the first one.
The new sound signal is installed in the reverse order.
Relay and fuse malfunctions
If the sound element is working, but the signal does not work, you should look for a break in the electrical circuit.
First of all, the 3S fuse with a rating of 16 A or 20 A, located in the mounting block under number F7, is checked. The electric motor of the cooling radiator fan is connected through the same fuse. If the fuse frequently blows, you can increase its rating to 25 A. This will compensate for the load while the fan and sound signal are operating simultaneously.
What to pay attention to
Although there are no requirements in GOST (except perhaps a fine for the absence of a signal), it is important to remember that high-frequency beeps are standardized, so make sure that the main frequency remains unchanged. In addition, you should not choose horns that imitate a steam locomotive or other vehicles that a pedestrian or motorist in the oncoming traffic simply does not expect to hear. Think about your health, as doctors do not recommend using signals with a frequency of more than 440 Hz. If you are planning to purchase a powerful multi-voice horn, then do not forget to take care of high-quality sound insulation in the car. In addition, pay attention to the following nuances:
- Before purchasing, you should make sure that the vehicle battery will “pull” the selected horn. If you plan to combine several beeps, the battery will discharge very quickly, since such “toys” are voracious and consume about 20-25 A.
- When choosing a horn, check with the seller whether you will need to connect the horn to power or whether you will need to purchase a compressor (which may be included) for operation.
- If you need more bass in the horn, then choose low-frequency models, and vice versa, for a subtle sound, high frequencies are better suited. For a polyphonic melody, both are used.
- Remember that voltage is different in cars and trucks. For cars it is 12 V, and for trucks it is 24 V.
You can find out how many melodies the horn plays, as well as how many bells it has.
Installing an additional button on the VAZ 2107 sound signal
The moving contact between the steering wheel and the steering column of the VAZ 2107 fails over time. His foot loses elasticity and the contact parts no longer touch. To prevent such a situation, car owners often install an additional button to sound a sound signal, duplicating the functions of the button on the steering wheel, that is, connecting the relay to ground. It is installed in any convenient place, most often on the instrument panel near the steering wheel.
An additional button is installed as follows.
A button connected in this way will repeat the functions of a button on the steering wheel.
Personal experience shows that using the signal button installed on the instrument panel is inconvenient. You won’t be able to get used to it enough to promptly sound a beep without looking at it. As a result, precious fractions of a second are lost when they could be vital. It's worth spending the money and taking a little time to fix your steering wheel signal.
Pneumatic (air) signals. How to make a powerful signal
The principle of operation of such horns is reminiscent of the ancient “horns” that were installed on horse-drawn carriages and the first steam cars. The air moves from the compressor through a special tube, causing it to vibrate and make quite loud sounds. There are many varieties, from 1000 rubles to 30,000 rubles. We have the cheapest ~1200 rubles in the local car market. Today we will upgrade the signals. And so for this you need: The signal itself is like faa faa A cylinder from a used fire extinguisher And an electronic valve. The first point can be dealt with easily, the price of the issue is 1200-1800 rubles in any car market. And with the remaining two it is a little more difficult. And then it dawned on me, what if instead of a storage tank we simply use a second pump. In any case, the pumps are not the most powerful, there will be an increase in power, but not 100% of course, I think it’s worth waiting for a 30% - 40% increase in power. I’ll say right away that there will be no tests with sound recording through a camera or phone! There is also nothing to take measurements with. It will be a purely personal opinion, it is your right to believe or not. In any case, it is not possible to transmit sound volume through the camera. And so let's go. For the upgrade we will need: The signal itself is of the faa faa type. An additional pump. A tee tube to fit into. We already have a signal, all that remains is to buy a pump at the local car market and a tee at a hardware store. I bought an additional pump for 400, and a copper tee for 75 rubles, why copper, but I just came across one that matched the diameter.
Before we begin, a few words about delivery. The parcel arrived in a simple black package. It was not even wrapped in bubble wrap, but in thin foam rubber.
Package
The box was damaged, as was the fastening inside.
Broken mount
Looking ahead, I will say: the pipe itself is plastic with a chrome coating, imitation metal. I will even say that all the signals of this form are the same, as if they were produced at the same factory, even if you buy them from China, or in local stores. Everything inside the box is standard: pipe, pump, hose and mounting bolts
So. Everything was purchased for an upgrade. True, the pump turned out to be blue, but it’s okay, they are the same.
And a tee We are figuring out how to arrange everything compactly.
Yes, it is better to coat all the joints in the pipe with sealant before final assembly, since they do not inspire confidence; you can use any automotive sealant, since we use it as glue, so that nothing comes loose due to vibration. In any case, it won’t be worse, since we still want to add an additional pump, and this is an additional load.
Now you can install. We will install it on a Chevrolet Niva. Secure with one bolt and 1 thick tie
not to look nervous
The old signals were installed between the radiator and the grille
We open 4 screws and carefully bend the plastic grille of the bumper, since it cannot be removed separately from the bumper, it is one piece.
This is how life and the aggressive environment punished them. In winter, salt and reagents are constantly poured onto the road, and if you don’t wash the car for a couple of weeks, you can see a thick layer of white coating. Because of this, membrane signals often stop working. Mine went through a major overhaul a year ago, if you pay attention you can see traces of cutting and different fastening bolts in diameter, this is because due to rust it was not possible to open them any other way.
There won’t be a video of me driving and scaring passers-by with my signal, I’m not the same age anymore, and junk tinting was banned a long time ago. As a result, what I can say is that it became louder by about 50% percent, purely my subjective opinion. There is definitely no problem that you won’t be heard! It would be possible to measure consumption with one and two pumps. If someone is very interested in this, write in the comments, I will measure it and add it to the review. The price of the product is now too high. Those who want to repeat it can buy it in any store, even a local one. Well, if someone has points or coupons, you can do it via the Internet.
In the summer I want to make a signal like that of trucks, instead of a compressor, these or a car pump. There is a fire extinguisher cylinder, all that remains is to find the electric valve. I think the auto truck shop will have it. That's all. Thank you for reading to the end, happy shopping on the Internet everyone.
The product was provided for writing a review by the store. The review was published in accordance with clause 18 of the Site Rules.
Installation of a pneumatic sound signal on a VAZ 2107
Some car owners install a powerful pneumatic sound signal on the VAZ 2107. Installation of such a device is quite simple. You will need a grinder, a drill and a standard set of plumbing tools.
First you need to determine where the horn and compressor will be located, and then make brackets to mount them. Typically, the pneumatic signal is installed behind a decorative grille in front of the radiator.
Installation is carried out in the following order:
We install the pneumoklaxon on the brackets.
We mount the compressor on the standard signal brackets or on the panel near the radiator.
We connect the horn and the compressor with a hose from the pneumatic signal kit.
If the current consumed by the compressor is more than 5 A, according to the scheme described above, you will need to install an additional relay to be on the safe side.
A pneumatic horn is impractical because it is equipped with a compressor that has a delay in starting. The compressor is short-lived and may quickly require replacement; moreover, in severe frosts, the compressor may fail and the signal will not sound.
In practice, the installation algorithm for a pneumoklaxon is determined by its size, type, design of fastenings, etc.
FakeHeader
That's it, the mechanical part is over, let's move on to the electrical part. As a rule, the horn device is located behind the engine radiator grille, directly in front of the main radiator device. As practice shows, often the cause of failure lies in their oxidation, so it makes sense to clean the contacts. Already crimped wires with terminals are sold in stores. Using this circuit, you can connect almost any powerful device and control it with a small, beautiful key. I planned to do it from the front, instead of the standard one, but I couldn’t unscrew the grille mounting bolts. Connecting an air signal If you need to connect not an electric, but an air sound signal, the connection procedure will be almost the same as described above.
To do this, you will need to dismantle the relay and set the resistance measurement mode on the multimeter. The difference is that the wire from the relay does not go to the sound signal itself, but to the compressor engine, which supplies air to the signal. We mark the corner at the installation location, saw it off, and drill holes for attaching signals from the Volga. This petal may burst over time; sometimes the cause should be sought in the jamming of the pressure rack. So we bring to your attention a diagram for connecting an audio signal through a relay. It is universal for most cars, with the exception of those cases when audio signals are used that receive mass through the body, for example Volgov's, for which the diagram is slightly different.
That's it, the mechanical part is over, let's move on to the electrical part. (easy and fast) Volgov Signals on VAZ 2107
