Mobile music Castle — inventory of car audio development Chronicle

What is a car audio, car audio is the most basic condition is a function of the sound playback. Sound system, at least the following points to be qualified as audio. First, the software and the media, then the sound source, the sound source is able to decode out software and multimedia agencies. For example, to play the radio called tuner, commonly known as radio; play the cassette called the cassette holder, CD recordings, is called CD-Player for compact discs. It also requires power amplifier and speakers.



Although the sound equipment for cars, just a kind of auxiliary 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.

Radio Radio

As early as 1923 United States first emerged mounting radio radio car, then many car can step in its footsteps in the dashboard assemblies installed radio radio. This time the car radio radios are tubes, until the 1950s appear after semiconductor technology, car radio, a technological revolution, with the gradual replacement of semiconductor has tubes, improves the life of the car radio. Nevertheless, car radios also have revealed a number of problems, due to the use of harsh environmental comparison are subjected to vibration, high temperature or low temperature, humidity, electromagnetic interference, etc., causes the antenna and the radio connectors appear between poor contact, radio frequent signal is weak or even not receive radio.

Cassette recorder

In the early 1970s, tabbed 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. Until the late 1980s, more 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 20 Watts or so. Cassette recorder is not perfect, if you do not pay attention to clean the heads, or put tape on the loudspeakers near magnetic material, tape sounds become smaller or even silent phenomenon, sometimes tape volume too tightly can cause sound tone or not to automatically change with tail, more crazy tape cannot enter or exit with spaces, but this is usually because the tape gets wet.

Multi-disc CD and MP3

Today, car stereos and has entered a new era, to power multiple output, multiple-speaker surround sound, multi-CD, HD. The CD because of the laser head is affected by dust, moisture, etc., will also appear dudie slow or even read it, and so on, to solve the problem, as long as usual a little note in-vehicle health and occasional cleaning laser head of lens. As technology continues to improve, the world of audio manufacturers will also be car audio for a specific industrial sector, in view of the car's special environment, take full account of sound effects, using high-tech manufacturing car audio equipment and its transmissions of sound completely comparable with the home audio. For example, svw's long graceful grade version with high-grade u-radio with single-disc CD player and MP3 capability, AM/FM/CD/MP3/WMA, playback functions, the use of virtual 6 CD/MP3 player, you can very easily zhuagui technology will CD-Audio format discs music into the vehicle's built-in flash storage media to store music time 7.5 hours; 8 speaker rings around four car layout to the door, combined with powerful playback system, front and rear rows of passengers as the provisional theater-like surround sound entertainment enjoyment.

Now, there is already a variety on the market for advanced audio car dedicated equipment, some car audio enthusiasts will power amplifier and electronic network is housed in the car trunk, the subwoofer large-caliber speakers and other model loudspeakers were embedded into the rear window of hoarding and door panels, use separate DC power supply, power output of up to 100 Watts, beautiful, and rich timbre are wrong, put inside the narrow space into a pleasant music room, provid beauty.

Car audio in fact in the seas of the world sound, because the automotive environment is very bad, including vibration, high temperature, noise, electromagnetic waves can interfere with the in-vehicle electronic equipment normal work, so car dedicated audio equipment from design and process requirements are stricter than home audio, but the price is not cheap, in this sense, the high-performance car audio actually today's sound-world top class products.
