This year marks the sixtieth anniversary of the founding of China's automobile industry is also very interesting things, from the first car of Jiefang automobile assembly line to now auto market's "big four" and "four small" pattern, see China has weak came into the world power. And car audio is a witness to the people living, cultural literacy, mental Outlook and life quality improvement of important basis. Now let's recall from 1949 on 2009 years history of domestic car audio.
Although the sound equipment for automobile, is only an ancillary equipment, performance of the car has no effect. But as people on the enjoyment of increasingly demanding, car manufacturers are increasingly attach importance to a car audio equipment, and use it as a basis for evaluating car comfort. The history of car audio is also the history of electronic technology, electronics technology, every significant technological progress are driving the development of car audio.
1949-1950, automobile Assembly is in the a dashboard assemblies installed radio radio. This time the car radio radios are tubes;
1950-1960, semiconductor technology, car radios a technological revolution, with the gradual replacement of semiconductor has tubes, improves the life of the car radio;
1970-1987, cassette recorder has entered the market, a play cassette motor retractable dual-purpose machine appears in the car, at the same time movement began to apply the integrated circuit;
1987-1990, General car stereo to a tabbed Wrapup and dual-use machines and a pair of speakers, speakers, based around two way channel, on the dashboard assemblies on either side, over the door, on the back of the rear seats, retractable dual-purpose machine output power up to about 20 Watts;
1990-2001, high power multi-output, multiple-speaker surround sound, HD-type laser CD machine, take full account of sound effects, using high-tech manufacturing car audio equipment and its transmissions of sound completely comparable with the home audio;
2001-2007, car DVD, GPS navigation special formal recognition in the automotive market, and selling. The global positioning system (GPS) and LCD (LCD-DISPLAY) two-part. Built-in GPS antenna receives from the 24 satellites around the Earth GPS satellite in at least 3 satellites the passed data information, the resulting determination of vehicle's current location.
Navigation system itself is equipped with a storage of the electronic map Info for CD-ROM, by GPS satellite signals to determine the coordinates of this match, you can determine the car on the electronic map of the exact location. On this basis, will achieve the recommended traffic navigation, route, and many other features. Drivers simply by watching the picture on the monitor, listen to the voice prompts, the control keys on the display to achieve these capabilities to easily drive. As well as some domestic helper electronic brand enterprise in this stage.
In this phase, MP3, also praised in the market;
2007-2009, multimedia navigation. Multimedia navigation system in the first generation adds telephone and playback features, General with GPS satellite navigation and positioning, route planning and VCD/DVD, TV, etc. The basic principle of multimedia navigation and the first generation of basically the same, can be counted as the first generation of product upgrades. Multimedia navigation while retaining the first generation of electronic maps and electronic voice function, also adds to the front steering prompt information, that is, for some important and complex traffic junctions can be displayed on the screen in advance at zoom map and striking tip guidelines correct driving direction.
2009---, GPS navigation and wireless communication combining networking features of navigation, a map can be found in the House and car, the two storage, to find the destination without the driver on the map to find the Service Center do, therefore, in the navigation when you start or stop. Second, effective utilization of real-time traffic information for "shudu-" navigation, automatic avoid traffic jam. The third is the Service Centre map update, the realization of the whole network update, even if it is stored in the map on the car can also be achieved through a wireless download at any time. At the same time, you can increase the security control, remote detection, WEB connectivity, requests for assistance and rescue services.
As the domestic consumption ladder, on-board electronic technology is developing rapidly, in the future of in-car audio electronics industries will present a major change and shuffle. As a result of foreign automobile manufacturing giants constantly pouring into the Chinese Auto market, foreign high-end models with foreign automobile manufacturing giants coming to emerge in the market, while domestic brand cars will also be involved in, resulting in domestic high-end multimedia interactive system will be increased to 2% to 5%; consumer perceptions and consumer demand to GPS/DVD quick growth, market share will rise to 40%, GPS/DVD instead of CD in the audio market in occupies the first place; it is difficult to keep the CD 50% market share, will be reduced to 35%, reduced to audio CD's second major market; as the emerging markets of on-board audio, MP3 from 14% to 20%, become a bright spot in the market, but MP3 is only a temporary transition technology to reach 20% market share already will not have outstanding performance; 80 's cassette markets will be high-end multimedia interactive systems, GPS/DVD, CD, MP3, it is from this cassette machine disappears car audio industry. The future of in-car audio industry pattern will be GPS/DVD as the leading, high-end multimedia interactive system development in the market, CD, MP3 from the high, mid market disappeared into the low-end market forces.
