The car horn is the frequent use of the device while driving, if the speaker fails, the car will be very inconvenient. Sometimes according to the speakers, the sound is not like a mosquito called, is very hoarse, even voice. This is what is what causes it? Man of few words, said the cut to the chase.
(1) sometimes does not ring the car horn switch, horn and sometimes loud, sometimes does not ring, multi-speaker switch contacts within the contact, some are also speakers.
(2) hoarseness mostly due to the plug connection is bad, especially the steering wheel around each contact, due to frequent use, easy to make contact frayed.
(3) does not sound to first check the fuse to see if the fuse, and then disconnect the speaker plug with a multimeter to measure whether there is electricity here in the horn switch. If there is no electricity, should check the speaker wiring harness and horn relay

The current level of program source device and the power amplifier has been done is very high, the sound system consisting of a high-quality audio, high
-quality amplifier and speaker system, the playback quality depends primarily on the speaker of the Speakers also known as speaker systems, it is
extremely important aspect of the sound system. Great sound playback quality of the entire sound system.
Speaker classification, common in the professional audio, classified as follows:
1 by the use of the occasion: divided into two major classes of professional speakers and home speakers. Home speakers are generally used for home
playback, which is characterized by delicate playback sound quality and more refined appearance `beautiful, the playback sound pressure level is not too
high to withstand the power is relatively small. Professional speaker in general for the dance hall `karaoke hall` theaters `halls and sports stadiums
and other entertainment venues. The high sensitivity of professional speakers in general, the playback sound pressure, intensity, and to withstand the
power compared with home speakers, the sound quality rigid, the outlook is not very sophisticated. Professional speaker in the monitor speakers, its
performance home speakers closer to the appearance is generally more sophisticated `small, such monitors are often used in home Hi-Fi sound system.
2 Press the playback frequency: can be divided into full-band speakers bass speakers and subwoofer. The so-called full-band sound is able to cover
the low-frequency `IF and high frequency range playback of audio. Full-band sound of lower frequency is usually 30Hz-60Hz, maximum frequency of 15KHz-
20KHz. Only in the small and medium sound system with a pair or two pairs of full-band sound to fully take on the task of playback. The bass speakers and
subwoofer are generally used to supplement the full-band sound of low frequency and ultra-low frequency sound for speakers. The type of speaker is
generally used in the `medium-sized sound system, to strengthen the sense of the intensity of low frequency sound and shock. Use, mostly through an
electronic crossover (crossover) frequency division, the low-frequency signal into a dedicated bass amplifier, and then push the bass or subwoofer.
(3) by end-use: generally divided into the main playback speaker. Monitors and back to listen to speakers. The main release the audio speakers are
generally used as the main speaker sound system, bear the main playback tasks. The main level audio speaker performance to a great impact on the quality
of the playback of the entire sound system, can also choose the full-band speakers plus subwoofer combination playback.
Monitors for the control room, recording studio for program monitoring use, it has a small distortion, wide and flat frequency response, very little
modification to the signal characteristics, most of faithfully reproducing the original appearance of the program. Back to listen to the speakers, also
known as stage monitors, and general use for the actors or members of the band on stage or in dance halls to listen sing or play sound. This is because
they are located behind the main playback speaker on the stage, can not listen carefully to their own sound or the band playing acoustic, it can not be
well with or find the exact feeling, seriously affecting the performance effects. Generally return to listening to the bevel-shaped speakers made, on the
ground, which can be placed on the stage will not affect the overall shape of the stage, but also on the stage to listen carefully to playback, not
caused by audible feedback to the microphone howling.
The press box structure: can be divided into a sealed speaker, vented speakers, labyrinth speakers, acoustic tube speaker and multi-cavity resonator
speaker and so on. Which professional speakers used the most is inverted relative to the speakers, which is characterized by wide frequency response,
high efficiency, sound pressure, in line with the type of professional sound system speakers, but because of its low efficiency, it is less professional
speaker applications, mainly for home speakers, only a few monitor speakers with closed box structure. Sealed speaker has the advantages of simple design
debugging, wide frequency response and good low-frequency transient characteristic, but the higher the requirements of the dial sound unit. In a variety
of speakers vented speaker and sealed speaker occupied the majority of the proportion of many structures in other types of speakers, but the proportion.

Produce many adverse effects of car audio listening environment listening effect, therefore,
put forward higher requirements for the installation of wiring of the car audio system.
(1) the smaller the car audio wire resistance, the less power consumption on the wire, the
higher the efficiency of the system. Even if the wire is very thick, due to the speaker
itself, the reason will lose some power, without making the whole system efficiency of 100%.
(2) the smaller the resistance of the wire, the greater the damping coefficient; damping the
greater, the greater the redundancy vibration of the speaker.
(3) the greater the cross-sectional area of the wire (thicker), the smaller the resistance,
the greater the tolerance of the current value of the line, the greater the output power is
allowed.
(4) the power of insurance choice. The main power line fuse box the closer the better the
car battery, the insurance value of size according to the following formula to determine:
Insurance value = (system average total rated power and × 2) / vehicle power supply voltage

The vast majority of cars on the stereo installed in the dashboard or the location of the sub-dashboard, while the narrow space within the dashboard, the volume of car audio console is bound to be limited on a common mounting holes standard size, called the DIN (German Industrial Standard) size. The standard DIN size 178 mm × 50 mm × 153 mm (length × width × depth). Some more advanced car audio console with multi-disc CD audio system, mounting hole size of 178 mm × 100 mm × 153 mm, also known as 2 times the DIN size, more common in the Japanese machine. Individual brands of car audio console is a non-standard size, can only specify to install certain types of car audio. Therefore, the purchase of car audio, must pay attention to the audio host size and the instrument panel mounting hole size whether adaptation.
Car audio installation in addition to the instrument panel mounting hole size, more importantly, the entire sound system installation, especially the speakers and mechanical installation techniques. Because the pros and cons of the sound of a car, not only with the sound quality of relations, also has a direct relationship with the sound installation techniques.

In the previous section, we took great lengths to explain the technical characteristics of speakers with electric speakers [the pros and cons], on the sound principles of the speaker, headphones electric speaker and the speaker does not have any difference, but Because the use is not the same, so the technical requirements are not the same, this talk on a headset with speakers.
Headset speaker also called the drive, electric speaker sound principle, also called habitual moving coil speaker. Its design must meet the small-diameter, lightweight needs. Otherwise can not be installed to the ear shell.
Requires both light can not harm the performance of Nd-Fe-B has become the preferred material of the magnet, it has a very high flux density up to ferrite 7-14 times, a normal headset NdFeB magnets, you can easily adsorption from the objects of weight a few times.
Most of the headphones is not divided by design, it is actually a full-band speakers are responsible for a very wide frequency response, this is not an easy thing. To achieve the full band sound of a single diaphragm, the diaphragm needs to be done very light thin and there is a certain intensity, speakers with diaphragm almost failed. Moving coil speaker diaphragm, the thin PVC material specific formula manufacturers confidentiality], the thickness of the thinnest can reach a few microns, in order to enhance the diaphragm strength, the diaphragm is generally suppressed to strengthen lines, which can improve the high frequency response, and the split vibration to produce a certain deterrent effect.
The structure of the cone speakers, fold ring and centering piece is used as a suspension system, dome speaker diaphragm repression fold ring suspension, moving coil loudspeaker suspension system, but with the diaphragm have been integrated, this dome speakers are very similar, basically, can be dynamic speakers as a derivative form of the dome speakers.
The voice coil is also key, because it must be very thin diaphragm, voice coil weight will impact on the working status of the diaphragm, copper voice coil weight heavier, more CCAW Voice Coil CCAW Voice so-called Copper- CladAluminumWire, Chinese as aluminum, copper-clad wire, it effectively reduces the weight of the voice coil. This voice coil of the speaker using the speaker application, but the scope of application is relatively small point.
Headset design, there is a speaker, after all, common, that is, moving iron speakers, it\\ s very small, so much for which the design of the ear headphones. Speakers using the speaker in a similar type, called the electromagnetic speaker, or call the speaker of the reed. Moving iron speakers can be regarded as a derivative of the electromagnetic speakers simplify varieties.
Moving iron speaker power, drive a U-shaped iron plates, conduction to the shell sound, its sound principles and dynamic speakers. This type of speaker of the biggest advantages is the high sensitivity in the early period for hearing aid design, widely used in-ear headphone design in recent years things. Moving iron speakers also have a greater disadvantage of the performance of the frequency response is not enough, the sound of the metal taste is too strong, However, as technology advances, these shortcomings have better improvement.
In order to overcome some shortcomings of the moving iron speakers, and some high-end models and custom headphones, multi-speaker plus the divider to achieve a more perfect frequency response, such as Ultimate Ears the UE 7 Pro, with two woofer, a tweeter, which are located in two separate cavities. The earplugs interior design divider, high-frequency, low frequency via the two catheters output, reverb in the ear canal. This is somewhat similar frequency of the speaker and the multisection.
Headphone speakers did not use the special features on the principle, in front of the introduction of large format on the speaker, also applies to the headphone speakers will not repeat it here, but special headset applications, will lead to the design of the headphone speakers by volume, weight , etc., constraints, design space is small. Headset design for a class of flat-panel electrostatic loudspeaker applications, but few in number, not as a basic knowledge of science, interested can read the relevant technical information.

Introduce home audio distribution
Introduction
Mainly two-channel home stereo Hi-Fi system and multi-channel AV system, the former is what we often say 2.0 or 2.0 powered speakers Passive speakers and amplifier combination; the latter is the home theater sound system, and is generally 5.1 channel, 7.1 channel speaker in recent years, however, is endless, which to some extent from the 7.1-channel sound card appear. And have appeared in the 4.1 channel.
Home audio sound effects related to many factors, such as room size, room shape, speaker of the display layout and more. A sound system in the same case, we can not change the size and shape of the room, only through the audio layout to improve the acoustics. In order to get better sound, home audio layout is very important.
Two-channel sound system
2.0 Speakers
For 2.0 speaker is – \"triangle\" pendulum method has been very mature.
First of all, between the two speakers to maintain a certain distance. Typically, this value is probably between the 1m-2m.
The speaker and the wall distance is best at least 30cm. This is because many speakers in the box with holes down the back speakers at work when it is discharged through the air. Especially high-power output, if too close to the wall, the impact of air to the rear wall easily, this will cause the bass muddy.
To face the speaker towards the listener. This means that it should form a certain angle with the desktop, rather than parallel to the relationship. As for the distance between the speaker and you, too practical to consider the practical issues.
2.1 Speakers
That pursuit is definitely Hi-Fi 2.0 speakers, which is mentioned before the two-channel Hi-F system. At present, there are a lot of on the market, or a common or ordinary consumers use 2.1 speakers. The placing of these speakers also pay attention to the requirements of 2.0 speakers but no less complex.
In general, you can put it on the computer desk below the subwoofer, and two satellite speakers on the computer desk just need the top left and right enough.
Multichannel audio systems
4.1 Speakers
In order to bring better sound field surround effects, there have been 4.1-channel speaker. Its basic composition is evolved from the 2.1, but the name change, the four satellite speakers are divided into front, rear two. In place, it s two front speakers and subwoofer with 2.1 speakers placed no difference. The two rear speakers are generally required on your left and right rear two positions, and the best axis aligned with you. Height of the best with your ears at the same horizontal plane. If not, then ask them to both the vertical axis of the speaker plane can be the best point to your ears, and most do not exceed the distance of 1.5m.
5.1 Speakers
With the increasing popularity of home theater, 5.1 channel and 7.1 channel speaker s attention is also increasing. But certainly not a good thing to have good sound effects, compared to the previous, the 5.1-channel speaker placed much more complex.
■ placing the subwoofer
Because the human ear is not sensitive to the direction for the bass, so it can be placed in the corner. But this time, we must note two points:
A subwoofer is definitely not easy to form on the resonance of the object. If so, when the subwoofer work, the object also followed shock, a great impact on quality;
Second, the subwoofer does not matter must be close to the rear wall. This is because many of the subwoofer is designed after the inverter. The phase inversion towards the hole, if not a certain distance, not to play bass on a. Therefore, at least some distance away from the wall.
■ front speakers
It is best with ear angle of 45 degrees -60 degrees, where the distance from the speaker about the listener s position, that monitors the distance from the listener decide. In general, the front speakers can be placed in parallel for the listener or the same place as the 2.0 system, but no matter how placed, highly to be as identical as possible.
■ Center Speaker
The center speaker is only one principle – must be put in place in front, left and right speaker is the perpendicular bisector line. Although it does not matter from front to back, but still good to try to moderate.
■ Surround speakers
And the front speakers should be placed face to face or with the human ear into a 60 degree angle display, and it is best to hang in the rear and above the head 60 cm -90 cm.
In short, a good 5.1 positioning system, positioning should be clear, there is no fault. Like a bullet across the sky, there should be a very complete change in the position of feeling, without feeling or feeling is not clear, you need to adjust your speaker location. The voice dialogue should be sent from home, feeling the speaker in front of you. Low frequency, the 5.1 system the emphasis is on shock, large dynamic scenes should have a good contrast effect. The more high-quality 5.1 system, you should be bass eloquent and magnificent.
7.1 Speakers
For the 7.1 speakers, the more it is based on the 5.1-channel has been further improved, an increase of two surround speakers, it reached number four, namely: front left, right, left rear, right Surround. Therefore, it is also based on the location of placing a 5.1-channel speaker changes.
For the subwoofer and the front, center speaker, 7.1 channel system with 5.1-channel system is almost the same.
Four surround speakers placed, the principle is the same, that is, the surround speakers to the formation of the human ear 60 degree angle, and preferably higher than when you are sitting at the head of more than 60-90cm.
Where change is that the surround speakers placed in your left front, left rear, right front, right side after the position to be placed face to face manner, that is, four speakers are facing you. Also, ensure that both the left and right speakers, two speakers were in the same straight line.
There is, left, right, two surround speakers, and you should be at the computer screen with vertical straight line, and with a pair of rear surround speakers at a same plane, were hung on both sides of the wall (you can also on the bracket).
fraud alert six kinds of amplifier means
In recent years, the rise of home theater power amplifier to drive the domestic production of the surge. Among the many brands of
China-made amplifier lacking in some of the fine. But there are a lot of “fraud” of poor quality power amplifier. Here are just some of
the false practices and I worked out methods of identification, we want to buy power amplifier help.
1 amplifier for a lot of people think that “the more the better sink” idea, poor quality of most of the use of a toroidal transformer
power amplifier, and a lot of double-loop with a fever of cattle. However, such a poor quality silicon steel ring of cattle, winding
process not pass. Resulting in low efficiency, the actual power is small, especially in the quiet, it is easy to hear the ring cattle in the
“hum” sound.
2, and a large head and small volume of domestic imports of brand-name capacitor charging capacitor. Some manufacturers even
earlier with a backlog of re-packaged charging capacitor installed the new capacitor. Capacitor voltage and the actual capacity of these
failed to reach the nominal value. Capacitance products such contests generally light.
3, the low-end 4558 or 082 5532 and other high-end charge amplifier. I found that many so-called polished from 5532 is actually
4558. Have to import China-made tube amplifier tube filling, especially the most fake Toshiba tube.
4, the poor tend to have a 5-channel amplifier or 7-channel output. But in fact many of the power amplifier surround and center
channel is the main channel by the series resistance comes about. Although some power amplifier with a separate amplifier, but only
after a delay of a simple process, there is no dedicated decoder circuit sound field processing circuit. If you find such differential
amplifier when the surround and center channel alone can not adjust the volume, use a series resistor from the main channel from the
fake surround.
If the nominal with Dolby Pro Logic decoding functions do not have the noise test. Or only when the input signal is mono surround
speakers also sound, the amplifier is pseudo-surround sound amplifier. For Q-Sound using SRS and amplifier technology, audition on and
off by comparing the function and select different surround modes can also be identified around the true and false. Here need to
remind everyone that, although the real part of the audio manufacturers such as Dolby decoding using the M69032 chip, but also not
certified by Dolby Dolby logo affixed. This amplifier can not guarantee the necessary degree of channel separation performance is also
a fake list.
5, the lack of complete protection. Although low-grade machines have anti-shock protection boot, but most omit the necessary
overcurrent, overvoltage, and output DC protection. Resulting in poor reliability of the machine, if there are problems is likely to burn
expensive speaker. For this type of false identification techniques, first by looking at the schematic design to determine whether there
is complete protection. Second, output short circuit, if the amplifier does not appear to protect action. It is likely that eliminating the
need for these protection circuits, or at least adjust the poor.
6, A to B charge, one-sided pursuit of multi-function and appearance to the neglect of the circuit design level, and as a selling point,
especially a large blow blow. Which are “Advanced” false practices. For these “unique” power amplifier, if consumers are not familiar
with audio equipment, the best selection of knowledgeable people to help, and try to select the audio manufacturers of the products
more reliable.
Finally you are ready to buy power amplifier to a friend mentioned three proposals. First, adhere to the “good enough, easy to use”
principle, do not over-the pursuit of function and appearance. For Hi-Fi enthusiasts, a two thousand dollars AV amplifier may be less
than one thousand dollars more is two-channel amplifier. Second, remember to be reasonable with amplifier and speaker. Third, we
must satisfy the principle of their ears, not specially prepared by the dealer s “earth shattering” deceived by the voice, to bring a few
familiar high-quality CD on the machine, may make you benefit.
Special development trend of car audio car
China s auto market after the most to promote the concept of the role of a technology or invention that is “car only.” In essence,
dedicated car a few years ago the host of a general-purpose vehicle market segments, its direct role for all to see, host special car of
the car after the direct release to the maximum extent of market demand, and this process will continue the momentum of inertia
was first-class development. From a technical perspective, the car is not a mystical special utility model invention, at best, only from
the hardware and the original car audio systems and establish a non-destructive of the agreement. In fact, popular car special reason,
from a deeper perspective of China s auto market after spending reflects the universal rule: non-destructive of the individual needs to
achieve. In other words, dedicated car built on a broad basis of consumer psychology, reality, the status as a luxury car still has not
changed, especially the midsize sedan, consumers do not want to destroy the original vehicle equipment or style, but effectively
There are audio-visual and other personal needs, this is a special car up to today s consumer psychology prerequisite, which is why the
PND why the first host in Car DVD navigation, and so far the best interpretation of the enduring.
Host dedicated open-car market car
Following the success of the host vehicle to car-specific as a stepping stone to make a million units-level market, automotive supplies,
automotive supplies, especially of immediately picking up special car, special visual reversing car, car-specific floor mats, car dedicated
LED special reading lights … … car car market with Chinese characteristics, a synonym, although car-specific process, there will be
some “cottage” of a case, but in the long run, private car is the breakdown of the domestic automotive supplies market needs, but
also can effectively leveraging consumer market product development direction.
As an integral part of car audio, car-specific pre-and post-class car in full swing sound wants to come in stark contrast. October 2008,
the author in a show with a renowned company CEOs chat after class after class, when the future development trend, when talking
about car into the 4S shop dedicated host channels, the CEOs believe that the host into the 4S shop special car, the biggest
advantage for the 4S shop to solve technical problems, basically no pressure sales, which is car-specific host to the biggest potential
advantages of pre-installed. In fact, when the car stereo does not have to enter into the terminal 4S stores or mass retail channels,
the reason, there are also stark contrast to the profit compared to the host, saying “sake Reds face, gold heart moving Road”, 4S
shop certain retail channels or terminal “phase of ownership and the lesser evil”, select the profit margin is high and the pressure of
small car sales dedicated host.
Begun to taste the sweetness of the special car audio car
In fact, car audio car specialization there is no technical bottlenecks, only need to solve installation problem, that of the original car
horn bit and the original car audio adapter cable to the plug issue. Passage of time since last year, after the fierce class dedicated car
started to heat up, ready for domestic brands, and “focusing instead on a large fortune.” Tasted the sweetness, the foreign brands of
fashion, such as who the BMW 3 Series, 5 Series, 7 Series supporting Germany ETON, its domestic upcoming Volkswagen, Toyota
series car special audio products. I had and made a simple exchange of the manufacturers, they believe, in the U.S. and European
markets, similar to car-specific installation of this non-destructive of the original car has become a consumer concept, the Chinese car
market car audio exclusive has just begun.
Specialization course after class car industry is beneficial, beneficial owners of a good thing, but the car also need to grasp the special
direction of the process, such as built in the channel, is inherent in the traditional use of modified car audio shop, or the reconstruction
of the retail terminal channels? In the mixer, the need for specific models, the positioning of the audio equipment, and personal
listening needs to be treated differently. All in all, exclusive of car audio car is good, but not exclusive of each brand of car can be
accepted by the market, car special is the trend, the broader market segments, manufacturers launch products, but should focus on
plan ahead to meet future market demand.
Another terminal stores the future profit growth
On a deeper level, market development strategy, automotive car audio exclusive of the right time, the reason I say that is because
before, the market acceptance has been verified by a dedicated host for the car. Practice has proved that car-specific host-specific
since the introduction of the concept car, and achieved rapid growth, while domestic car the first car audio exclusive gold who has
tasted success “Hunxing.”
Domestic automotive supplies, particularly in the automotive electronics market, with examples of technology emerging market
demand for the release, As first steps, but a late start in the car industry-specific areas, car audio in the car market may be dedicated
to the final direction of the search , following the success of open end car audio specialty store has been modified, full access to
supplies an opportunity for the retail terminal channels, capital and labor to have a certain strength of the end retail stores, the special
car of car audio products will gradually grow to its mainstay business One of the next year or two, after the class car-specific products
will be converted end car audio shop, following another car after the host-specific long-term profit growth.
car stereo equalizer in the role of
1, the sound system used in the purpose of graphic equalizer
Already has a host – Amplifier – speaker these basic sound system, in order to improve the sound quality of this system and regulation
of the more detailed, more complete the music player, will join the equalizer in the sound system.
Sound system used in graphic equalizer (Graphic Equalizer) audio can be improved in some bands or attenuation, it is intended to
correct room acoustics and speaker inside the amplitude-frequency characteristics of the defects, or to polish the sound processing,
you can locate the car in and around the sound field to make adjustments to suit personal preferences and enhance the sense of the
scene. Frequency equalization (Frequency-response equalization, also known as balanced Equalization or correction balanced Corrective
equalization) circuit, which is in the sound system in order to get a flat overall frequency response, for some correction or adjustment
of the signal transmission frequency characteristics of a network circuit, it can be taken to distinguish between the various frequency
method, resulting in a flat overall frequency response. Such as the Kenwood DPX-8020MD with its own internal 11-band graphic
equalizer circuit, is a typical example, as well as host internal amplification circuit, also has a different frequency equalization.
2, the sound system to use the graphic equalizer in either
Graphic Equalizer has been all the rage, a sound combination of essential parts, but it disappeared a few years ago, almost nobody
cares. There are many reasons, first of all most of the goods of poor quality of the graphic equalizer on heavy burst will produce
discernible additional distortion and noise, reducing the overall sound quality. Second, if used improperly, the balance often makes
heavy burst damage, resulting in heavy burst frequency over the muddy, dull and lacking mid and high frequency of excessive and
harsh. The pursuit of HiFi sound quality for the lovers, are intolerable, and now with the popularity of audio and knowledge increase,
the sound quality has very good ability to identify, graphic equalizer fans will gradually be applied to Hi-Fi arena. As the graphic equalizer
is given in the appearance of a beautiful feeling, like young people to pursue the goal, pay attention to the most beautiful screen,
choose the host with a graphic equalizer. Now the host is generally 2DIN with graphic equalizer. However, for fans of Hi-Fi is not
recommended to use this host, because the host has done a modification within the source, so the listener is not the pursuit of
quality, as a general appreciation is possible.
3, how to use the equalizer for sound compensation
In recent years the host of many brands such as: SONY, KENWOOD, VDOdayton, to listen to in order to obtain a sense of comfort, to
set some special effects to produce a frequency compensation deal with EQ, a variety of preset tuning mode, suitable for playing
different songs to create a sound effect, providing the perfect sound environment for non-professionals do not make timely sound
field adjustment disorder, just press the button you can reach a preset preset effects, such as ROCK (Rock), VOCAL (vocal), CLUB
(club), NEW AGE (avant-garde), POP (pop), JAZZ (Jazz), CLASSIC (Classical music), etc. Frequency of the sound source for the
principle of compensation is not affecting the loudness of the melody played, even if the volume is large, we can not make people feel
uncomfortable. According to the most perfect combination of personal preferences to the effective environment.
