subject: Reviewing The Old: China Six Years Of Development Of Car Audio - Car Audio, Car Audio, Car Dvd-auto [print this page] The sixtieth anniversary of the founding of this year, the Chinese auto industry is also a very meaningful thing, a liberation from the licensing of motor vehicles off the assembly line to automobile market is now the "big four", "four small" pattern, can see that China has fully entered the world powers from the ranks of the weak. And Car Audio Also witnessed people's living standards, cultural quality, morale and quality of life to enhance the important basis. Now Let's recall from between 1949 and 2009, the development process of the domestic car audio.
Audio equipment for the car is concerned though, just a supporting device, the operating performance of the car has no effect. But as people enjoy higher and higher requirements, car manufacturers are also increasing attention from car audio equipment, and use it as a basis for evaluation of one car comfort. Car audio history of the development is Electronic History of technology, electronic technology, each of the major technological advances are driving the development of car audio.
1949 --- In 1950, the automobile assembly is installed in the dashboard assembly radio radio. Waiting time is used by radio radio tube;
1950 years - 1960, there semiconductor technology, the car radio there a technical revolution, with the gradual replacement of the semiconductor control tube, to improve the life of the car radio;
1970 years - 1987, cassette tape recorders into the market, one can play cassette tapes in the car with a retractable dual-purpose machine in the car at the same time the movement began to apply integrated circuits;
1987 - 1990, the car audio and more generally to a retractable dual cassette machine and a pair of speakers based on combinations of two-way left and right channel speaker, and some placed on both sides of the dashboard assembly Some put the door, some put the rear back seat, retractable dual-use machine output power is about more than 20 watts;
1990 years - 2001, high-power multi-output, multi-speaker surround sound, multi-type laser Diep CD Machines appear to fully consider the car's acoustics, using hi-tech manufacture of car audio equipment, the transmission of sound entirely comparable with home stereo;
2001 - 2007, Car DVD , GPS Dedicated car navigation formally recognized in the automotive market, and cause hot. By the Global Positioning System (GPS) and liquid crystal displays (LCD-DISPLAY) of two parts. Built-in GPS antenna will receive from around the Earth 24 GPS satellites in the delivery of at least three data information, thus determination of the current car position.
Navigation system itself, the information with electronic maps stored CD-ROM, via GPS satellite signals to determine location coordinates and this match will determine the car's precise location in the electronic map. On this basis, will achieve traffic navigation, recommended routes and other features. Drivers only by watching the monitor screen, listen to voice prompts, you can control the display of the keys to achieve the above functions to ease to drive. Such a good helper and some other domestic own brand of electronic business at this stage the rise.
