Music is the sound of our happiness, and it can also be a time tunnel for us to pursue our memories. Basically, we all like music very much. I believe many friends like to enjoy the beauty of music and the comfort of the journey in the car, but at this time, we must pay more attention to the stereo in the car. So today, the car editor will simply introduce the maintenance and troubleshooting methods of car stereo to friends.
car audio maintenance and troubleshooting: car audio.
after buying and installing the car stereo, you can enjoy pleasant music in the car! When you are stuck in a traffic jam in Lu Yu, high-quality CD surround sound and a series of notes come out rhythmically, and your impatience will soon disappear. However, the filth and dust in the basic city are the biggest enemies of your car stereo, so you need to pay attention to cleaning and maintaining your car stereo frequently.
1. Be sure to wipe with a wet cotton swab.
The pinch roller of an audio cassette player and the magnetic head of a CD player are basically places where dust is easily accumulated. The most important position in a CD player is the laser head. Because the laser head is a fragile part and quite expensive, it should be maintained. At present, some car stereos basically consider the problem of dust prevention in the design process, but protective measures are also necessary. You can often wipe the cassette, cassette, CD player tray and sound system panel with wet cotton swabs. A good practice is to gently absorb the dust with a wet cloth. As for the cleaning of keys and knobs, cotton swabs can be reused.
2. use cleaning tools to clean tapes and CDs.
besides keeping the audio host clean, tapes and CDs must also be kept clean. Moreover, the dirt on tapes and CDs will not only affect the sound quality, but even damage the sound. When the head of CD player rotates at high speed, if it encounters dust, it will make the head deviate from the original laser track, resulting in sound distortion and damage to the head. It is understood that most video stores basically have cleaning tools for tapes and CDs.
3. Be sure to check the tightness of the adhesive tape.
speakers cannot be ignored. Its grille cover is a very easy place to accumulate dust, which will reduce the volume of the speaker. Before listening to music, you'd better check the tightness of the tape. If it is lifted, you need to roll it up with a pen. If it is too tight, it needs to be lifted by rewinding. If the tape is not used or closed for a long time, it is best to eject the tape, which may affect the deformation of the pinch roller after a long time.
4. Play the CD slowly, and change the CD less
Winter is the high incidence of damage to the laser head of the car stereo, and it is easy to generate static electricity due to the dry climate. It's best not to touch the tray directly with your hands, don't take the middle, put it in slowly, try to avoid changing the tray frequently, and try to plug the tray lightly.
car stereo maintenance and troubleshooting: maintenance
mainframe maintenance
Now most cars are basically equipped with CD players. High temperature and humidity will directly damage the service life of the laser head, so in order to prevent direct sunlight, it is best to use a sun visor to resist the scorching sun when it is raging.
due to the hot and humid weather, it is easy to cause fog on the CD. If the wet CD enters the host computer directly, the reading speed of the laser head can't keep up. At the same time, the electrical components are wet, which may even damage the laser head. Humidity and high temperature are the main reasons for the aging of electronic components and laser heads.
it is not advisable to turn up the volume immediately after the car is exposed to the sun. Because the working state of electronic system will change with the change of temperature, increasing the volume immediately will not only damage electrical appliances such as speakers, but also affect the service life of the host.
another natural enemy of the laser head is dust. Although the problem of dust prevention has been considered in the design of car audio, it is still very important because of the different road conditions in China. When the road environment is poor, the small partner should immediately close the window and pay attention to the cleanliness inside the car.
car CD players mostly adopt suction cup design. As long as the CD is placed at the entrance, the mechanical structure will automatically suck in the CD. Some friends don't understand this structure and often push the disk in by hand, which will not only damage the disk, but also damage the tray structure in the machine.
speaker maintenance
dustproof: the harm of dust can't be prevented, but we can minimize it. Do a good job of door sealing. When there is dust on the road during driving, close the window as much as possible. If there is dust on the main unit, wipe it with a wrung-out towel. Moreover, after cleaning the cab, it is best to open the window for a period of time to allow most of the water in the car to evaporate before closing the window, which can prevent moisture well. When a car is driving on a dirt road, it is not necessary to open the window as much as possible to prevent a lot of dust from pouring into the car from the outside. It is best to adjust the empty external circulation to the internal circulation.
moistureproof: water is the most feared thing for electrical appliances. Always check whether the window sealing strip is tightly sealed. If not, it will flow from the car door to the speaker when washing the car or raining, which will damage the speaker or burn out the main circuit. Close the window when cleaning the car, open the window after cleaning, and circulate the air to evaporate the water in the car. It makes a sound when it is wet. Ho ho ho. Sound is closely related to audio-visual effects.
protection against violent vibration: violent vibration will affect the lifting or damage of internal components of the audio. When cleaning the stereo, don't beat it hard to shake off the dust. When the road conditions are bad, you should drive smoothly at low speed, which not only ensures the car and sound, but also ensures safety!
disk maintenance
the CD does not need to be placed on the dashboard. In hot summer, CDs are easily deformed under the scorching sun.
for the tape part of audio, the same precautions should be taken to avoid heat and moisture. If the temperature is too high, the tape will deform and get stuck when it is put into the host. If the directory label on the tape is turned up, it is better to tear it off directly, otherwise the tape will not be returned. When you don't listen to the tape for a long time or turn it off, it's best to quit the tape. Because the pinch roller will temporarily hold the adhesive tape when it is closed, it will affect the deformation of the pinch roller after a long time.
after the disc is not used for a long time, there will be dust and scratches. When wiping the dust on the surface of the optical disc, it needs to be wiped along the direction perpendicular to the audio track.
when using the host, you must choose a genuine CD with good quality. Because there are often uneven disk surface or round disk hole in cam-, these hidden dangers will basically affect the failure of laser head, such as jumping point, and directly damage the life of laser head.
maintenance and troubleshooting of car audio: attention should be paid to the installation.
Safe
In the process of disassembly and assembly, it is not allowed to damage the original car circuit to cause short circuit, and it is not allowed to connect the wrong circuit when installing the equipment, which will cause adverse consequences. The installed equipment needs insurance measures. In case of overcurrent, it needs protection, just like installing a time bomb, otherwise it is easy to catch fire. The audio circuit must not interfere with the computer and electronic equipment in the car, otherwise there will be trouble. It must be installed by professionally trained personnel to ensure safety.
disassembly technology
in the process of modifying the sound, the original sound needs to be disassembled first. Whether it can be disassembled is the fundamental problem of modification. Because the screws can't be seen on the surface of the instrument panel, it is necessary to pry open the decorative piece to see the screws. The disassembly operation process needs to be professional and strict, otherwise it will be easy to disassemble. Step 2: In order to wire and replace the speaker, it is necessary to remove the door panel, door edge, instrument panel, seat, decorative panel, etc. Special tools are needed in the disassembly process, and the original parts need to be kept intact, otherwise it will be unsightly, and poor sealing will produce noise.
is the product qualified?
There are many counterfeit brand-name equipment in the market, so you must identify them when you buy them, or you will be in endless trouble. Some low-priced equipment can't see quality problems from the appearance. However, the internal components are basically inferior, and the circuit design may not meet the specifications. This kind of equipment has poor sound quality, which is prone to failure and even causes nature. Need to go to the store authorized by the manufacturer to buy, don't worry about using it.
how is the sound quality?
there is no need to listen to brand-name products. The varieties of famous brand factories are also divided into three grades: high, medium and low. You don't have to listen to the grade you buy. The most fundamental thing is that they need to be matched, installed and debugged by professionals to achieve good results. It's not a simple matter to connect a few lines casually. Basically, the sound field positioning and phase can't be wrong, otherwise the effect will be unimaginable.
consider after-sales service.
car stereos are used for sports, and the environment is a little poor, such as temperature, humidity, vibration, dust, etc. , which is easy to cause all kinds of faults. Maintenance, warranty and repair are very important issues. Cheap purchase of parallel imports, refurbished products, clearance products, stolen machines, etc. The warranty card is fake and there is no after-sales service. If it is damaged, it must be repaired or scrapped. Is it worth it? At present, the equipment sold in specialty stores is basically not necessarily expensive. There are many cost-effective devices that can enjoy good after-sales service, so why not?
installation environment
the installation of a small shop was done in the open air. The work clothes of the staff were dirty and the stereo was installed, but the inside and outside of the car were dirty. It is a good thing to buy a new car for a stereo, but it is a sad thing to bring many bad consequences. The specialty store operates indoors. Its advantages are: 1. Clean, ensure that the car is clean inside and outside. It is not affected by temperature. When the temperature is too low, it is easy to be damaged when removing plastic parts. No matter what the weather is, it can work normally. Because of the light, you can basically work day and night. The customer has a good lounge.
after reading the brief introduction of car series, do you need to know about the maintenance of car stereo and the troubleshooting methods of common faults? So, do your friends like the knowledge that Bian Xiao Auto introduced to your friends today? Little friends should basically know how to maintain the car stereo, and when listening to songs on the road, they must pay attention to the car driving ahead! Finally, I hope that the introduction of the car system can solve the problem for friends.
