The speaker in car audio, commonly known as the horn, plays a decisive role in the entire audio system, and it can affect the style of the entire audio system.
Before car audio modification, I believe everyone will want to know about audio modification package plans, such as two-way frequency, three-way frequency, etc… But because customers still do not have a thorough understanding of the role of these speaker types, So today I want to take everyone to popularize the classification of car speakers and the characteristics and performance of various speakers.
Car horn classification: can be divided into full-range, treble, mid-range, mid-bass and subwoofer.
1. Full-range speakers
Full-range speakers, also called broadband speakers. In the early days, it generally referred to the speaker that can cover the frequency range of 200-10000Hz as full frequency. In recent years, the full frequency speaker has been able to cover the frequency of 50-25000Hz. The low frequency of some speakers can dive to around 30Hz. But unfortunately, although the full-range speakers on the market are full-range, most of their frequencies are concentrated in the mid-range range. Flat, three-dimensional sense is not so obvious.
2. Tweeter
The tweeter is the tweeter unit in the speaker set. Its function is to replay the high-frequency signal (frequency range is generally 5KHz-10KHz) output from the frequency divider.
Because the main function of the tweeter is to express the delicate sound, the installation position of the tweeter is also very particular. The treble should be installed as close as possible to the human ear, such as on the A-pillar of the car, above the instrument panel, and some models are located at the triangular position of the door. With this installation method, the car owner can better appreciate the charm brought by the music. up.
3. Alto speaker
The frequency response range of the midrange speaker is between 256-2048Hz.
Among them, 256-512Hz is powerful; 512-1024Hz is bright; 1024-2048Hz is transparent.
The main performance characteristics of the mid-range speaker: the human voice is reproduced realistically, the timbre is clean, powerful, and rhythmic.
4. Mid-woofer
The frequency response range of the mid-woofer is 16-256Hz.
Among them, the listening experience of 16-64Hz is deep and shocking; the listening experience of 64-128Hz is full-bodied, and the listening experience of 128-256Hz is full.
The main performance characteristics of the mid-bass: it has a strong sense of shock, powerful, full and deep.
5. Subwoofer
Subwoofer refers to a speaker that can emit low-frequency sound of 20-200Hz. Usually, when the energy of subwoofer is not very strong, it is difficult for people to hear, and it is difficult to distinguish the direction of the sound source. In principle, the subwoofer and the horn work in exactly the same way, except that the diameter of the diaphragm is larger, and a speaker for resonance is added, so the bass that people hear will feel very shocking.
Summary: According to the article, the classification of car horns is not determined by the sound size of the horn and its own size, but by the frequency it emits. Moreover, the speakers in each frequency band have different performance characteristics, and we can choose the sound effect we want according to our hobbies.
Then, the two-way speakers we see when we choose speakers generally refer to the mid-bass and treble, while the three-way speakers are treble, midrange, and mid-bass.
The above content allows us to have a cognitive concept of the speaker when modifying the car audio, and have a preliminary understanding of the audio modification.
