Car speaker classification
1. According to the time when the car leaves the factory
According to the time when the car leaves the factory, it is divided into original products and after-sale products. The original products refer to the original products, which are the speakers installed on the car panel when the car owner buys the car. Different grades of cars choose different grades of brands to match them. However, no matter what brand you choose, the function and sound quality of its speakers are limited (except for particularly high-end cars). The reason is that car manufacturers must design the car speaker buttons to be larger from a safety point of view, and the function of the speakers must also be extended. The test of time only agreed to use (some of the advanced functions can not be used, because it has not been tested for a long time).
More famous car speaker manufacturers include Philips (PHILIPS), Alpine (ALPINE), CLARION, Panasonic (PANASONIC), Pioneer (PIONEER), Fuji (FUJIS) and Sapphire.
The speaker brands supporting domestic mainstream brands of cars are: FAW-Volkswagen Philips and Panasonic as the main components, Pioneer and Alpine with individual models; Shanghai Volkswagen is mainly equipped with Philips; Guangzhou Honda is mainly equipped with Alpine and Panasonic; Hainan Mazda is mainly equipped with Panasonic and Alpine. send.
After-sales products refer to the speakers that consumers choose when they are not satisfied with the car speakers after buying the car. Because it is not restricted by the car factory, it can be described as the Eight Immortals crossing the sea and showing their magical powers.


2. According to the geographical division of car speaker brands
According to the geographical division of car speaker brands, it can be divided into Japanese brands and European and American brands. This is also a classification that everyone knows better, and home speakers are often compared with this classification.
Japanese brand speakers are good at reading and finishing sound quality. Sound reading refers to the process in which the host obtains signals from digital and analog audio sources. Japanese brand speakers are very mature in technology, and the sound quality is pure and delicate. The retouching of sound quality refers to the use of mathematical methods to create various field effects to please the human ear, such as BBE, DHE, various field simulations, etc. These functions break the true color of the sound source, but are more in line with the habits of the human ear, so it is very To please consumers. Generally speaking, the sound quality of most Japanese speakers is relatively balanced, which is in line with public consumption.
European and American brand speakers are known for their true restoration and low-range shock in power amplification. Ouli people pay attention to the true nature of music, while some manufacturers pay special attention to bass. Among household speakers, European and American brand power amplifiers and speakers are more highly regarded.
3. According to the specificity of car speaker manufacturers
According to the specificity of car speaker manufacturers, it can be divided into professional manufacturers that only produce car speakers and wide-area product manufacturers that produce both car speakers and other home appliances. Representatives of professional manufacturers that only produce car speakers include Alpine, Clarion, and POCKFORD, and wide-area product manufacturers include Panasonic, Pioneer, Sony, and Philips.

3. Composition of car speaker system

The car speaker system includes five parts: antenna, receiving device, speaker correction, audible frequency amplification and speaker system.

1. Antenna
The antenna is used to receive the radio wave transmitted by the broadcasting station and transmit it to the radio frequency modulation device through the high-frequency cable.

2. Receiver
The receiving device is a radio tuning device that selectively receives high-frequency electromagnetic waves emitted by the radio station and demodulates them into audio electrical signals.

3. Tape player
The tape player is used to play music signals recorded on tape.

4. CD player
The CD player is used to play the music signal recorded on the disc.

5. Equalizer (balanced volume controller)
The equalizer is used to adjust the characteristics of the sound (music) signal to adapt to the car listening environment.

6. Power amplifier (speaker amplifier)
The power amplifier is used to amplify the weak audio signal to enough power to drive the speaker.

7. Speaker
The speaker is an important component that ultimately determines the performance of the speaker in the car box. The size of the speaker diameter and the installation method and location in the car are important factors that determine the performance of the speaker. In order to appreciate the stereo speakers, at least two speakers must be installed in the car.

4. Composition of car speaker system
The basic condition for a speaker system to be called a speaker is that it has the function of playing back sound. A speaker system must include at least the following points mentioned by the author before it can be qualified as a speaker. This is true for any speaker system, and car speakers are no exception. Car speakers mainly include three parts: host, speaker, and power amplifier. The host is an important part of the car speakers, just like the human brain, what kind of sound to make must be controlled by the brain. At present, the popular hosts include CD hosts, MP3 plus CD boxes and CD/DVD hosts, and car CD speaker systems are generally used.
Software and media: What do you want to listen to? Traffic and traffic programs? Then you have to turn on the radio station and tune to the correct channel. Want to watch TV in the car? It's even simpler. The LCD screen has long been one of the protagonists of the car speaker system, even if you want to watch DVDs. Want to listen to music? Put a record of your choice, whether it's a CD, MD, or cassette, regardless of which singer's singing is included.
Audio source: The organization that can decode software and multimedia is called audio source. This proper term may seem incomprehensible, but it is actually a very simple thing! The one that plays radio is called tuner, commonly known as radio; the one that plays cassette is called cassette player; the one that plays CD records is called CD-Player. , And also a compact disc.
Power amplification mechanism: Most of the sound signal intensity controlled by the pre-stage is only a few volts, which is not enough to drive the unit (see Article 5). Therefore, the signal must be given some "power pills" to make the signal stronger and make it stronger It can be calculated in watts (W), so that the mechanism that strengthens the output of the signal is called a power amplifier, which is commonly known as a power amplifier. Generally speaking, the total output power value of the speaker system, that is, the sum of the output power of all the power amplifiers in the system, is used as the grading of the speaker system in terms of magnitude.
Loudspeaker: The device that turns electrical energy into sound waves is called a loudspeaker. The mechanism that can convert the signal into sound, in addition to the generally common circular or elliptical reciprocating coil type speaker, there are other types of speakers! For example, the ribbon type (Ribbon) that produces sound with a metal belt, and is driven by static electricity. Electrostatic speakers with flat diaphragms also have a place in speakers. However, moving coil speakers are still the mainstream in car speakers. The impression is that except for the ribbon-type car tweeters of Infinity and Taiwan EVIL, the others are common moving coil monomers.
Transmission mechanism: For a complete speaker system, the wire is an indispensable component, but the wire is often overlooked. In fact, the quality of the wire will directly affect the quality of the sound, because the difference in the design and specifications of the wire from the material, twisted structure, diameter, insulation and impedance value, etc., will affect the signal or power transmission. As for the use of wires, different devices require wires with different design orientations, such as power supply, grounding, start-up, signal, horn, optical fiber, and wires required for special systems. They are all designed due to their different requirements. The difference. For example, for speaker cables that require sound quality, the purity of the material must be as high as possible, otherwise too much impurities will affect the full performance of the sound. In addition, the terminal between the wire and the equipment is also very important. Whether the contact is firm or not, the size of the contact area, the design and material of the connector, and whether the grounding is good will also have a significant impact on the sound effect.

5. How to choose car speakers
As most ordinary car owners, if you are not a car speaker enthusiast and have considerable financial strength, before choosing a car speaker, there are two points that should be determined first, first is how much you plan to spend to modify the speaker; then you have to consider Is it the type of music you like, rock, pop, or classical music. Remember to consider these two points and you can’t reverse it. If you determine the type of music you like before modifying the speakers, then you can be sure that your budget will exceed the standard. You should know that in the field of car speakers, from the perspective of equipment, It must be the more expensive the better. Some super car speaker enthusiasts have equipment installed on their cars worth hundreds of thousands or even hundreds of thousands.
In the car speaker modification, mainly from the two perspectives of sound source and sound quality. General audio sources include tape players, CD players, DVD/VCD/CD capacity players, MP3 players, MD players, etc. Now some car speaker enthusiasts have begun to use music hard drives with 1G storage capacity. But in terms of the effect and quality of music, it is recommended to use a CD player. The tape drive has a narrow frequency response and large noise; VCD has poor sound quality, but the advantage is that it has video effects, but as a car speaker, it is not recommended; MP3 is a compressed format, although the sound quality processing circuit is added to restore, but the sound quality Still can’t compare with CD; DVD’s sound quality is close to CD, but the overall comparison is still inferior to CD; MD’s sound quality is not much different from CD, but the sound sounds hard, and the overall sound effect is not as full, smooth and original as CD. Authentic.
Nowadays, there are many brands and types of CD players on the market, including single-disc, multi-disc, and all-in-one with a cassette player. Basically, they are mainly based on Japanese brand hosts, such as Alpine, Clarion, Kenwood, Sony, and Panasonic. , Pioneer, JVC, etc., the price ranges from seven to eight hundred yuan to several thousand yuan. In terms of product quality, there is not much difference, but different brands have their own unique characteristics. For example, Alpine is a professional car speaker, with perfect sound quality and excellent resolution, especially in the performance of middle and high frequencies, such as the performance of soft and lyrical and small bridge water and other sound effects, and it is also unique in terms of shockproof technology. , The supporting disc boxes are mostly six discs. At present, most of the low-end products of Alpine heads on the market are domestically produced; Panasonic, Kenwood, etc. have good stability; Pioneer and JVC have good performance in all aspects. Single-disc drives are more cost-effective. At the same time, you should choose models according to your different music hobbies. If you like soft and lyrical music, you can choose Japanese brands.
If you like to improve the sound quality, the industry has always had Japanese consoles and European and American amplifiers. From a professional point of view, the characteristics of Japanese power amplifiers and speakers are sharp and ear-piercing, and the overall effect is hard, while the fullness of the bass is weak. It does not sound like a bunch of hits, and the flexibility is not obvious, but for ordinary car owners In other words, whether it is used for new appreciation of ROCK, POP or symphony, it should be easier to create a corresponding atmosphere, that is to say, its overall adaptability and wide range of applications; if you are a ROCK fan, hope to get the unique ROCK The metal percussion that is too hard to make your heart dull, of course, you must choose American power amplifiers and speakers; for car speaker enthusiasts who are very picky in sound effects, they are pursuing each of the original sounds. A level and detail, to maximize the reproduction of music, which must use European power amplifiers and equipment, for example, HIFI fans will choose British or Danish power amplifiers and speakers.
After choosing cost-effective equipment that can meet your needs, the real work has just begun. In the words of industry insiders, five-point equipment and five-point installation; some even talk about three-point equipment and seven-point installation. Whether a set of good equipment can be used to the fullest, the key is to see the technician who installed the speakers for you. , His knowledge of automotive circuits, acoustic principles, music quality and appreciation level, operating proficiency, etc. will directly affect the overall performance of your car speakers. Whether the sound field positioning and phase of the whole set of equipment are accurate, whether the treble is clear and transparent, whether the midrange is smooth and pleasant, whether the bass is full and flexible, etc. In addition, for the current high-noise problem commonly found in domestically-made mid- and low-end cars, sound insulation should be done according to different situations. Therefore, don't think that installing car speakers is just a matter of simply connecting your carefully selected equipment with cables. When choosing an installation shop, in addition to choosing a larger-scale shop, you should also ask an experienced technician to operate it.
