Car sound is generated by the speaker system in the car. Car speaker systems are often installed in positions: taplo, A-pillars, door panels, pedestals behind the rear seats. The structure of speaker covers for audio includes:
Driver: The driver consists of a coil attached to the diaphragm, placed in a permanent magnet magnetic field. When current flows through, the coil will vibrate, creating oscillations that propagate out through the diaphragm.
Speaker cabinet: Generally, the speaker box contains all the drivers inside. The thickness, material and construction of the speaker cabinet greatly affect the sound the speaker emits.
Echo hole: The vents associated with the cabinet are arranged on the outside of the diaphragm. Furthermore, it is to both protect the diaphragm and allow the sound to escape.
Other accessories: power cords, jacks, speaker fixings…
Speaker covers for audio are installed in many different places in the car. Sound in general and car audio in particular are classified into 3 main sound bands corresponding to 3 frequency bands:
First, Bass: is in the frequency range from 20 Hz to 500 Hz: Bass is a low, deep sound range, indicating the bass of the sound.
Second, Mid: tones are in the frequency range of 500 Hz to 6,000 Hz: Mid tones are mid-range tones. Moreover, common sounds in life such as voices, animal cries... are in this range.
Third, Treble: is in the frequency range from 6,000 Hz to 20,000 Hz: Treble is the high range of tones, indicating the treble of the sound. Similarly, it is easy to imagine that the sounds are high-pitched and sacred.
The source of sound through speaker covers for audio is usually:
CD, DVD player: In the past, when CDs or DVDs were in vogue, car manufacturers often equipped their cars with CD or DVD players, when the audio was played through the speaker system.
However, nowadays CDs and DVDs are outdated, most new car models have gradually reduced, no longer equipped with CD / DVD players, instead only equipped with car screens.
Car entertainment screen: Car screen now acts as a tablet in the car. If connected to the internet, users can watch movies and listen to music online. Therefore, the sound from the screen will be played through the car's speakers.
AUX, USB ports: Through these ports, users can connect other devices such as MP3 players, phones, etc. to the car speaker system. Currently, car speaker systems mainly play sound from the car entertainment screen
Corresponding to 3 car audio bands, car speaker systems have 3 main types of speaker covers for audio:
Car woofer and subwoofer focus is a type of speaker that represents the bass sound of the bass range, the easiest to imagine is the drum sound. The woofer represents low frequency sound, while the subwoofer represents the ultra-low frequency sound.
The characteristics of subwoofer and subwoofer are large size, large cabinet to create full bass. Because of the large capacity, the subwoofer and subwoofer are often installed under the car seat or behind the trunk. Car subwoofers and subwoofers are usually installed under the car seats or the trunk
Car subwoofer has 2 types: Steam Sub and Electric Sub.
The subwoofer is a speaker that takes its signal from the car amplifier like other normal speakers without its own audio amplifier.
The electric sub is a speaker that integrates its own audio amplifier inside and has a frequency cutter to remove high-frequency sounds, leaving only bass with frequencies in the Bass range.
Mid-range speaker covers for audio is a type of speaker that focuses on showing mid-mid range sound, these are the sounds with the most common frequencies, the easiest to visualize is the human voice.
Therefore, the Mid speaker is considered a basic type of speaker, a must have. The available speakers that come with electronic devices such as TVs, phones, car monitors are all Mid speakers.
Mid-range speaker audio covers have an average size of 3-5 inches. Mid speaker is usually installed in the car door. Car Mid speakers do not necessarily have a speaker cabinet like Bass speakers. Usually people will use the door panel as a speaker cabinet. Similarly, mid speaker is usually installed in the car door
Treble speaker (also known as tweeter or treble) is a type of speaker covers for audio that exhibits high and high sound in the Treble range, the easiest to imagine is a high-pitched sound like a bird singing.
The car Treble speaker has a small size of 1-2 inches, usually installed in the corner of the steering wheel wax taplo, the A-pillar is located at the corner of the door glass, the car door panel.
On the other hand, ordinary cars have thin bodies and poor speaker covers for audio. Therefore, the sound system is even more important. This is considered a way to "save", helping to drown out the noise in the cabin. So that's why the trend of upgrading car audio is so "popular".
The trend of speaker tuning, upgrading car audio is "prosperous" again. Today's car is not simply a means of transportation, but also a place where people want to have a more comfortable and high-class experience.
Car audio "level" will help the car sound more standard, watching movies or listening to music more vivid. Since then, the trips are also much more interesting and emotional.
Generally, there are many types of car audio tuners, the most popular of which are the following:
Loudspeaker Sub
With this model, the original car speaker covers for audio system will be kept with only 1 or 2 extra subwoofers for the car. This is a way to save car sound for many people to choose, suitable for those who like the bass range. Moreover, car subwoofer level is suitable for those who like the bass range.
