With the huge increase in the number of cars, the problem of driving safety has become more and more prominent. If the Toyota recall in 2010, the Chinese car owners can still watch the fire across the bank, then the 3.5000 exposure of the "Kumho Tire" incident, so that Chinese car owners have to feel deeply "car safety, so close." At the 2011 CCTV 3·15 evening, the Kumho tires were exposed to serious problems in the production of tires. In order to ensure the quality of the tires, Kumho Tire has set strict operating standards, but in the manufacturing process, a large amount of refining rubber is added. The biggest victims of the Kumho tire incident were the majority of Chinese car owners, and the “automobile safety electronics industry” that had long been ignored by car owners and enterprises was finally taken seriously. On May 1st, with the implementation of the “drinking and driving punishment” program, the entertainment celebrity Gao Xiaosong’s helplessness and confession were reported in the major media tabloids, and the cold handcuffs in Gao Xiaosong’s hands made all the owners understand. Wine is not a mess, the country is really good, at the same time, for a time, car black box (also known as driving recorder), anti-collision system, fatigue warning system and TPMS (tire pressure detector), alcohol detectors and other products, in the market They are also selling hot. At the same time, remote security, remote diagnosis, road rescue and other car safety services linked to the Internet of Vehicles have also shown great commercial value, and the business prospects are bright. Is car audio still struggling in the “niche market”? In the Chinese car audio industry, which started in the 1980s, the glorious scene of “the sound modification competition everywhere” in the late 1990s no longer exists. Today, we can call the export audio brands, such as JBL, Pioneer and other foreign brands. There are only a handful of Chinese national brands. The car audio company “separating is a dragon, and it is a combination of insects” has always struggled in a “niche” market like audiophiles. Up to now, people who insist that the car audio modification is always a "niche" market are still not a few, "the sound modification is not suitable for entering the 4S shop" and the sound of "audio modification is not necessary" is still there. Of course, many companies are setting up standards for car audio, so that "feeling" becomes a measurable "feel", because with the gradual pursuit of quality life, the pursuit of music by car owners is definitely higher and higher. This year, some domestic enterprises have already been on the road of car audio popularization. Among them, Dongguan Changhe is one of the best. Its audio brand “Sounds of Joy” uses “special car audio”, “wild match, non-destructive upgrade”. The concept and the practice of “3,000 member stores” have achieved initial success.
