What is the reason for the noise of the horn on one side of the car door?

The reason why the sound becomes quieter.

3) Electromagnetic interference - this cause is more complex, many electrical equipment connected or not connected to the computer may cause electromagnetic interference, but it is easier to investigate, that is, the sound is very small, and the lack is not a little volume; And the volume is unstable, once the interference is weakened, the volume will become normal or relatively loud. Or, plug in and unplug the speaker plug, maybe the volume is normal, this can be checked.

4) Speaker volume knob - all turned on to the maximum, if the quality is fine, this one does not need to be checked.

5) Maybe the speaker brocade wire is broken, or the speaker paper cone is damaged.

6) Short circuit of speaker output, resulting in short circuit of car audio power amplifier, output protection; The sound is small.

7) The amplifier block is damaged.

8) The diaphragm contact gap has changed. Adjust the contact gap adjustment small screws on the horn to bring the sound back to normal.

In this case, you need to check the situation of the main unit, wiring and speakers.

This could be a problem with the speaker, a wiring problem, or a problem with the audio channel adjustment.

Summary. Dear, hello, I am happy to answer for you, the reason why the car audio is loud and the sound is small is as follows: the positive and negative poles of the audio are reversed:

The speaker and distributor are either to the navigation or CD, the positive and negative poles are reversed, and the audio cable can be connected backwards to try the chance to recover. The sound balance is not well adjusted: The sound on both sides of the audio is not the same, one may be that the balance is not adjusted well, and it may be because there is a problem with the woofer on one side.

Poor speaker leads: This is usually caused by mildew or poor welding of the voice coil leads, when the cone vibrates frequently, the breakpoint is sometimes connected and sometimes disconnected, forming an irregular sound and no sound fault.

The front and rear four-door speakers of the car audio, why is the volume of the speaker on the left door small, and what is the reason?

Dear, hello, I'm glad to answer for you, the reason why the sound of the car shed is loud and the sound is small is not as follows: the positive and negative poles of the audio are reversed: the speaker and the distributor or to the navigation or CD, the positive and negative poles are reversed, you can connect the audio line in reverse to try the opportunity to recover.

The sound balance is not well adjusted: The sound on both sides of the audio is not the same, one may be that the balance is not adjusted well, and it may be because there is a problem with the woofer on one side. Bad speaker leads:

This is usually caused by mildew or poor welding of the voice coil leads, when the paper cone vibrates frequently, the breakpoint is sometimes connected, sometimes disconnected, and the shape is dry and cautious into irregular sound and sometimes no sound fault.

Related information: It may be that the channel is tuned to a certain speaker; It may be a problem of open circuit of the speaker power line, you can check the wire reed bypass to see if it is unblocked, or cut off, if so, then connect the line. It's also possible that the horn is broken.

Auto AudioA sound receiver and playback device designed to alleviate the boredom of the driver and bystanders. The earliest use was the automobile AM radio, later the AM radio, tape player, CD player and compatible DCC, DAT digital audio. Now Qingxiang car audio has reached a high standard in terms of timbre, operation and anti-vibration, etc., which can cope with the bumps of the car on the rugged road to ensure the stability of performance and the perfect sound quality.

Summary. Hello dear! I'm glad to answer for you, the sound of the car tweeter is relatively small, this is very normal, for example, like some workbench mounted tweeters, this itself is an auxiliary speaker, so the sound itself is relatively small.

But if you increase the volume, the sound of other speakers can be improved, but the sound of the speaker you hear now has not changed, then it is necessary to consider that the power amplifier of the vehicle is damaged, and this situation generally needs to replace the power amplifier of the audio or replace the audio host to be solved. Kiss! I hope mine can help you, in addition, you can also click on my avatar to follow me, so that if you have any questions in the future, you can click on my avatar to consult me!

Looking forward to seeing you again! Have a great day!

This tweeter is what I just installed for half a month! , I went to debug the audio yesterday and came back only to find this problem.

Did you install it later? How many are there? If one is installed, then there may be a problem with the filter of the home decoration.

Hello, I am your exclusive technician, attentive, careful, dedicated to answering your car questions, for you to find the corresponding problem solutions and solutions! The front door horn of the car is quieter than the rear door horn, which may be due to the reasons and solutions: First, the sound effect and sound field are not set up.

The normal setting of the soundstage should be centralized. If you are in the front or back, the sound will be inconsistent, and even the left and right sounds will not be consistent. Find the sound effect in the system settings of the car machine, find the sound, and restore the settings again.

Second, the horn is faulty, if you rule out the first situation, it is called to check whether there is a problem with the horn. You can debug the horn before and after dismantling it. Generally, this kind of problem is more common because the sound field is not tuned well!

Summary. Hello, the reason why the car horn is quieter may be because: the battery loses too much power; Contact ablation, poor contact;

What is the reason why the car horn is quieter.

Hello, the reason why the car horn is quieter may be because: the battery loses too much power; Contact ablation, poor contact;

The reasons why the sound of the car horn becomes smaller are: 1. The wire of the horn may be disconnected, or the paper cone of the horn is damaged; 2. The output of the speaker is short-circuited, resulting in a short circuit of the car audio power amplifier, the output is protected, and the sound becomes smaller; 3. The power amplifier module is damaged; 4. The contact gap of the diaphragm has changed. Adjust the small screws and adjust the contact gap on the horn to bring the sound back to normal.

1. Horn moisture: The car horn device generally has good sealing, but with the increase of service life and the increase of the number of times, it will inevitably lead to a decrease in its sealing. As a result, when the car is washed, moisture and other moisture will enter the inside of the horn, which will lead to problems such as honking or not sounding the horn.

2. The horn circuit is broken: if the owner likes to press the horn for a long time in the process of driving the vehicle, then this will cause the resistance of the contact of the horn to be too large, which will cause the current of the horn circuit and the electromagnetic coil line to weaken, and finally cause the car horn to have a hoarse sound, or no sound failure. 3 Horn button is broken:

If the driver needs to sound the horn of the car, he needs to press the horn button, if he presses the horn button for a long time, it will also cause it to be damaged, and the damage of the button is also one of the factors that the horn does not sound. 4. Poor contact: The internal electromagnetic coil terminals of some models are not connected by welding, but by aluminum rivet crimping, at this time, if the insulating paint of its port is not properly handled, or the link is not in place, this will lead to poor contact.

In fact, there are many reasons for the low sound of the car horn, and the low sound of the car horn also has an impact on driving the car, so if you find that the car horn is quiet, you need to check or replace it in time.

If you honk the horn in the state of parking, it is likely that the battery is losing power, you try to start the vehicle to see if it can start, if it can not be the problem of the battery, otherwise it is the battery.

If the sound is still small in the state of the car, you can adjust the rubber on the back of the horn There is an adjustment bolt in it, and you can adjust the sound intensity of the horn clockwise. You can give it a try.

Lead a wire from the positive pole of the battery (or the positive pole of the generator) directly to the horn live wire connecting post, and then press the horn button, if the sound becomes louder, it means that the battery and its wire are well connected, and the fault is inside the electric horn, which may be contact ablation. If the sound is still small after maintenance, it means that the battery has lost a lot of power or the wire connection is poor.

In addition, poor contact: the internal electromagnetic coil terminals of some models are not connected by welding, but by aluminum rivet crimping, at this time, if the insulating paint of its port is not properly handled, or the connection is not in place, this will lead to poor contact.

It can be high-profile.

There are 2 screws behind the horn.

One is the wavelength of the tuned sound, and the other is the tuned frequency.
