What s going on with Changan Ounuo audio without sound? 10

Hello, you're usually a fault of the line, or a faulty horn.

Hello, in this case, it is recommended to focus on checking whether the connection line is broken.

Changan Ounuo audio is not loud What's going on:

Let's take a look at how the speaker works. When the horn button is pressed on the steering wheel or elsewhere, the current from the battery flows through the loop to the solenoid coil of the horn relay, which attracts the relay's moving contact switch and closes, and the current flows to the horn. The current causes the electromagnet inside the horn to work, causing the diaphragm to vibrate and produce sound.

The main line faults are the virtual connection of the line, such as: loose horn plug terminals, horn relay contact ablation, poor contact of the horn switch at the steering wheel, etc. However, in many horn failures, especially in winter, the problem is the failure of the horn itself.

Combined with our use environment and other factors, the failure of the speaker itself is mainly due to the following reasons:

1.Contact ablation: If the horn is pressed for a long time, it is easy to cause the horn contact to be ablated and the impedance will be generated, the current flowing through the electromagnetic coil will be weakened, and the electromagnetic attraction will not be able to attract the armature to drive the diaphragm to vibrate normally, resulting in hoarse or even no sound.

However, when the horn is constantly pressed, if the instantaneous strong current passes through the impedance, it can still work normally, so it will be good and bad.

2.Loose sealing is susceptible to moisture: Although the inside of the horn is sealed, if the seal is not tight, if it enters the fog or there is water vapor in the air in the internal space when washing the car, the water vapor can easily cause the contacts to be damp and unable to work properly.

3.Poor contact of solenoid terminals: some horns inside the electromagnetic coil enameled wire terminal joint is connected by aluminum metal rivet crimping, non-reliable soldering connection, if the insulating paint on the enameled wire at the end is not clean or the rivet crimping is not reliable, it is easy to produce virtual connection faults, resulting in poor horn work.

This kind of failure is the quality of the horn, which cannot be repaired, and can only be replaced with new parts.

Precautions in the use of car horns:

1.When washing the car, remember to prevent the horn from getting wet, and dry it with an air gun as soon as possible if you find water from entering the horn.

2.Try not to always press the horn for a long time, which can easily cause premature ablation of the horn contacts.

3.If the horn fails, try to seek the help of a professional maintenance technician, and do not blindly replace the horn, which is easy to cause unnecessary waste.

Exactly the same situation as you described, did yours solve it?

Big brother, is yours solved? Can you send a solution?

Is yours solved, mine is the same as yours, it has been troubled for a long time, and I suspect that the bridge bearing rings,

Chang'an 4S shop at Liuyang East Bus Station, they repair more cars, you can ask.

Changan Ounuo's radio has no sound, you can use the reset function to try whether it can be restored, the first possibility is that the machine is in silent mode, the panel should have a mute button, and it will be restored when you press it again. If you can't solve it, you can directly find the car body power distribution unit (crisper box), which number of the fuse is marked on the lid of the box is the radio, and directly unplug it after three or two minutes and plug it in. The car radio is a kind of voice entertainment configuration installed in the car, and it is one of the earliest and most common configurations of the car audio and video entertainment system.

Changan Honor is a new CDV commercial vehicle launched by Changan Automobile in 2012, which integrates global wisdom, after three years of repeated testing and verification, and is developed and designed by the world's top design team. Chang'an Ounuo is fashionable and magnificent, and its appearance is jointly designed by Chinese and European designers, and the European style is presented. The front face shape and ** grille are tough and magnificent, which is similar to that of Mercedes-Benz commercial vehicles.

The interiors are sophisticated, elegant, upscale and functional. NVH silent technology has reached the level of first-class joint venture cars, driving harmoniously and quietly, more comfortable and decent.

First of all, check whether the connection between the main unit and the speaker is loose or disconnected, whether the speaker is powered on, and whether the volume knob of the speaker is turned down to the minimum. Then insert the stereo in a few places to see if it will make a sound, eliminating the problem with the stereo itself. If there is a problem with the speaker itself, it can only be repaired or replaced.

The causes of the lack of sound in the midrange and how to deal with it are as follows:

1.Battery dead: All electronic devices in the car are powered by batteries. If the car's battery is dead, the audio will naturally be silent. In this case, you just need to charge the battery.

2.Audio plug falling off: If the audio plug falls off when the car is passing over bumpy roads, it can also make the audio sound lifeless. In this case, the stereo system should be removed and reinstalled.

3.Volume not turned on or in silent mode: This emotional situation is relatively easy to solve, just turn up the volume or turn off the silent mode of the audio.

4.Audio automatically turned off: If the audio is turned on for a long time and the vehicle does not start, the audio will automatically turn off after a period of time to prevent the battery from losing power. This is normal, just start the vehicle.

5.Modified audio mismatch: If the owner re-modifies the audio later, there may be no sound due to quality reasons or mismatch, and the repair shop should be checked.

There may be a problem with the disassembly and assembly audio system of Changan Ounuo car, resulting in loud and squeaky sounds. It is advisable to check that the audio system is properly connected, or to consider sending it to a professional car audio repair shop for repair.

If the problem still cannot be solved, it is recommended that you contact the manufacturer to change the service or professional maintenance personnel for help.

First pull out the middle air outlet, and then remove the three screws from the radio, and you can pull out the radio. Autoaudio is a sound receiving and releasing device set up to alleviate the boredom of drivers and passengers during travel.

Car AM radios were used first, followed by AMFM radios and cassette tapes, and progressed to CD** and DCC and DAT-compatible digital audio. Nowadays, car audio has reached a higher standard in terms of timbre, operation, vibration resistance, etc., and can cope with the bumps of the car on the rough road, ensuring the stability of performance and the perfect sound quality.

The most basic condition for a sound system to be called sound is that it has the function of **sound. A sound system must contain at least the following points in order to be called a sound system. This is true for any audio transport system, and the sound of a car is no exception.

Car audio mainly includes three parts: the main unit, the speaker and the power amplifier. It is the most important component of car hood audio, just like the human brain, what kind of sound it wants to make has to be controlled by the brain.

Millions of car purchase subsidies.

Changan Ounuo 2014 displacement can change the speaker by itself, the specific process is as follows:

1, Before installing a car horn, the first thing we need to understand is that there are several types of car horns. At present, there are three main types of car horns in the world: coaxial horns, subwoofers and kit speakers.

The workmanship of the coaxial horn is relatively simple, and all the registers are concentrated together, so there is some interference in terms of timbre. However, the ** of coaxial speakers is relatively cheap, so it is generally chosen for beginner car audio enthusiasts. The installation method is also mostly installed in the rear door of the original car horn position.

2. Because of the super low frequency signal, the subwoofer has a very shocking effect, which is more suitable for friends who listen to DJ and dance music. However, subwoofers are generally relatively large, so it is recommended to install them in the trunk of a car.

3. The installation of the set of speakers is more particular, just take the three-way frequency. The tweeter should be installed as much as possible at the level of the human ear, so as to create a better sound field. The installation method is also mostly installed in the original car tweeter position or after the A-pillar is inverted.

4. The installation of the midrange horn should be more convenient, and it is generally installed in the original car horn position. The woofer should be installed in the lower sound field as much as possible, such as under the car seat.

Hello! Yes, you can see the horn as long as you open the door interior, but you need to use the same size horn when choosing.

As for the sound quality, you can choose a woofer or use a coaxial speaker.

I hope it can help you, if you have any questions, please ask.
