Host, and speaker amplifier car audio system, the most important part. Host is like the human brain, what kind of sound to be issued,

may be controlled by the brain. The speaker is like the human voice, the sound is sweet, it is necessary to see how the voice. It is the

role of speaker audio signals into acoustic signals radiated to the surrounding air medium. Car speakers conical design of the most

common, which is installed in the vehicle because space is limited in the case, tapered design can be expanded as much as possible

the effective area of ​​the diaphragm, and diaphragm determines the effective area of ​​the low-frequency response speaker .

Accordance with zoning, the speaker can be divided into full-frequency, low frequency, medium frequency and high frequency of four

kinds. Form of energy conversion can also be divided into electrical, electromagnetic, piezoelectric, electrostatic and tablet, electric

vehicle to the main speaker. That is coaxial speakers full-range speakers, it s woofer and tweeter is designed in the same center line,

the outside is low, the inside is high, but the vocal point in the same physical location. This design can eliminate the high and low

frequency units due to the frequency range of different sounds caused by drift, but because of the high, the bass is emitted from a

point, so the larger the distortion sound. Divided into 2-way loudspeaker frequency and divide by 3, 2 divided by the tweeter and

woofer components, divide by 3 is coupled with the midrange unit. Because each unit is responsible for different frequencies, broaden

the frequency range, so as to solve the problem of sound distortion. However, because daily life, we hear the sound basically sent

from one point, while the frequency emitted by the speaker frequency of each unit, the installation of the physical location are

different. In this way, there will be voices drift phenomenon. In addition, the high, although the bass unit is responsible for different

frequencies, but it is bound to the existence of a critical point, so in a different position, given the same frequency, will produce

acoustic interference. To solve these difficulties, we must use the role of divider. Crossover As the name suggests, is to separate the

different frequencies, and sent to a different speaker unit. Of course, its function is not only this, it is also based on the characteristics

of the speaker to make proper adjustments in order to reduce distortion and interference.

Purchase proposal

1, the characteristics of music according to their preferences, select the speaker: If it is like to listen to the sound quality, choose

sound quality, outstanding speakers, if you like to play a large dynamic music, the appropriate choice of large diameter, heavy bass

speakers.

2, according to its own budget, choose the brand: Speaker brands currently on the market, prices are different, the brand s product

quality is good, but expensive. Specific conditions can be selected according to their own horn.

Glossary

Nominal Impedance: speaker at a particular frequency when measured at the input impedance value, it is the speaker sound system

with other parts of the important parameters match. If the data and power amplifier with a nominal impedance, there will be sound

distortion.

Sensitivity (SPL): When the speaker with 1 W power of the noise signal of 1 m in the axial direction of the sound pressure level

measured, which is reflected in the size of the speaker sound performance skills. When the optional speaker, to try to make both sides

of the consistent values ​​(controlled within ± 1 dB), or there will be very clear sense of focus.

When the car is no longer a luxury car owners in the replacement of the I, are no longer satisfied with a simple means of transport

use, more and more people have been trying to “mobile home” audio-visual experience to upgrade. Reporters recently modified in a

number of professional car audio shop found that last year topped the sales charts the first few hot models, just right of the audio

conversion, so that sort of wonderful gift to these models.

Nissan Li Wei

● [original car features]

Host using name brand CD player, resolution of a good owner to meet the general requirements in the car listening to music.

However, four 6-inch midrange speaker audio disc produced using wood pulp paper, it is generally only suitable for owners of the CD

to listen to human voices.

Not the original car loudspeakers, there is no crossover (crossover), can not reflect the level of a sense of music. Since the maximum

power of the factory speaker 40W, actually only 17W, so the volume is turned up and causing a large distortion. Moreover, the original

car no subwoofer, playing disco CD, 6-inch midrange speaker does not produce a sense of shock. In addition, it uses the paper plate

speaker sound, and very easy to cause moisture damage.

● [from experience]

Cars modified car stereo shop element responsible Huang Yan introduced, if you plan to add subwoofer, proposes to add a sufficient

luggage compartment is appropriate. Especially considering buying Li Wei to retain the original car owners think the advantages of

larger space, so choose a thin insulating bass, built-in three-way amplifier. If the budget is around $ 1000-2000, both before and after

facelift can set speaker, if purchasing more than $ 3,000 speaker packages, has been greatly improved treble sound, voice saturation

will be significantly improved.

Toyota Corolla

● [original car features]

Prior to use dual-frequency audio component speaker, not as some models two coaxial speakers mounted directly to trouble, and

adding AUX input and MP3, WMV and other mainstream media files playback, frequency of feeling is very strong, there is a kinds of

force to treble, alto, bass separate feelings. Significant loss in the high frequency band, the whole giving a soft feel, more suitable for

the general population.

● [from experience]

Open the original car radio, only the back two speakers out of the sound, the first two do not speak out. In fact, you can use the

following solutions: first, put a CD in, the volume to moderate; then, press the right button that large (on the left is the volume)

adjusted for each click on a button. It has five functions: first by the next, adjust the bass level change; by the second after the

regulation is under the treble content changes; third time after the regulation is by the sound around the speakers in the transfer;

according to the fourth after the regulation is sound under shift left and right speakers; according to the fifth after the regulation is

under the sound of low, medium and high variation.

Toyota Highlander

● [original car features]

The Highlander 3.5 Basic, for example, the original car with a CD host, the front door speakers are a pair of two-way speakers, the

back door is with a pair of coaxial speakers, can be said that a similar sound configuration, and most Toyota series car audio system of

choice similar. After all, few manufacturers are willing to in the original vehicle is equipped with high-level sound system, they pay more

attention to a balanced performance. Speaking of the original car s sound to audio enthusiasts point of view, and not too bright at all.

There reflects the owner, when the stereo sound on the 60 or so speakers will change the sound, and will hear the speaker pops

sounds like the original head power 45W, while the speaker s power is only 25W or so.

● [from experience]

After the conversion, began to feel the difference before and did not change is not large. If only for the back door of the two

speakers may start to feel after the maximum volume, there is no “pops” playing trumpet sound, and then travel for a distance, the

sound began to feel a slight improvement. Adjusted to 30 or so sounds, heavy bass can be felt, not scattered, the bass voice will

show very clearly.

Honda CR-V

● [original car features]

As a high volume of urban SUV models, CR-V in the sound, too, seems not much different from other similar models. 2010 facelift of

the CR-V2.0, equipped with multi-piece original host audio CD, CR-V2.4 is equipped with Honda accessories developed touch DVD

host, taking 6-speaker configuration. It s obvious lack of treble, weak low-frequency, intermediate frequency only slightly stronger

than the car.

● [from experience]

If the owners do not want to sound too much in the space occupied by the original car, it is recommended to install car speakers

amplifier package special-series, can be modified during the original car s damage to a minimum.

Eighth generation Honda Accord

● [original car features]

Compatible with the new Accord s audio system MP3, MWA and other formats, integrated sound good, there are also features speed

automatically adjust the volume, basically in line with user needs. But, overall, the original car sound because of cost considerations,

and have not upgraded door speakers, with plenty of room for improvement.

● [from experience]

Some owners said the Accord can not play the song, this may be due to player rate suited to play the system. You can try to use the

relevant software, will not be able to play MP3 files open, through the audio player software list, select the MP3 format conversion,

open the format dialog box, in the “Output Format” select “MP3 Encoder” and then convert sampling frequency of 44100Hz, set the

storage path, you can convert.
