Audio

And multimedia software that can decode the body - such explanation might seem difficult to understand, in fact, extremely simple, popular means for receiving broadcast signals to car radios, cassette tape player recorder, CD player, etc.

Pre-signal control

After the class generally known as the power amplifier, so between the sound source and amplifier, all for the music signal processing parts, are called before the class. For example, the host Car Audio volume control, is part of the former segment. In addition, such as bass and treble adjustment, left and right balance, before and after volume adjustment and Loudless loudness control, audio equalizer EQ, digital sound processor (DSP) belong to the first segment.

Power amplification mechanism

Before the sound level control signal strength is very small, not enough to drive speakers, these signals must be allowed to take "Dali Wan" that is, let the signal becomes stronger. Will enhance the success rate of the output signal of institutions, called PA, which is commonly known as the amplifier.

Speaker

Speaker is commonly known as the speaker, we usually see round or oval-shaped speaker whose scientific name should be reciprocating moving-coil loudspeaker monomer, in the field of car audio, in addition to a small number of U.S. and Taiwanese manufacturers produced a ribbon-type vehicle treble monomer, the other most of the products are moving coil speaker monomer.

Transmission organizations

A complete sound system, a combination of wire is indispensable components, but also often the most neglected part. In fact, good or bad wire will directly affect the sound quality, because the wire in the material, stranded structure, diameter, insulation resistance values ??and other design and specifications of the different, will directly affect the signal or power transmission effect, so the car stereo side, according to the needs of different designs differ in the wire.

Although the composition of car audio is very complex and we explain the fact loaded on the host in the car has won a lot of sources, the first stage, the basic structure of the three amplifiers. First, the host can receive the broadcast and pro audio files; Second, the host can adjust the volume, adjust the bass and treble sound; In addition, many hosts also have built-in power amplifier power output. However, there is a host does not have built-in amplifier, known as the "dumb machine", most of the dumb machines are high-level flagship product, the internal parts with more advanced material, the line structure is more complete, so the price is the most expensive.

Maintenance of car audio:

Good care in exchange for perfect sound quality

Many owners of car audio in use for some time, there could be difficult to read CD-ROM, sound quality deterioration and so on, this time people often choose to go to audio conversion shop repairs or simply replace a new set of car audio. In fact, in daily use in car audio if spare their maintenance, will effectively reduce the occurrence of the above, to extend the life of car audio.

Most cars today are equipped with CD player, heat and moisture are the two natural enemies of the laser head, so you should avoid direct sunlight, preferably in a sunny location to stop at what used to resist the sun visor.

After exposure the car immediately after the sound volume adjustment should not be large, because the electronic system of working conditions will change with temperature, and immediately turn up the volume may damage the speakers and other electrical appliances.

Another enemy is the laser head dust, although many car audio has been done in the design process dust treatment, but poor road conditions, the owner shall promptly close the window to prevent dust entering the vehicle. Usually with a wet cotton swab can often be disc CD player positions and wipe clean on the panel, front panel buttons and knobs on the cracks in the dirt should be cleaned up. Design with suction disc, just put the CD at the entrance, the mechanical structure of the disc will automatically be inhaled.

Speaker sound system as an important part, the same can not be ignored. Speaker grille is a very easy place to dust deposition, deposition of excessive dust will reduce the speaker volume.

Usually do not listen to the CD, not on the instrument panel, CD-ROM under the scorching sun exposure is very prone to deformation. Not long after the CD-ROM will have the dust, what should be kept clean, wipe the dust disk along with the audio track should be perpendicular to the direction of the wipe.

Surface dirt into the CD-ROM player will not, because dirt encountered in the operation mode, the laser head will deviate from the original track, in the production of sound distortion at the same time will affect their life.

With the onset of winter, when the use of car audio have to be careful, winter weather is dry, use warm air inside the city, it is prone to static electricity, the use of CD players, the best to touch other metal objects on board then contacts the host audio, because the static current is sufficient to cause instant damage to the host audio.
