Analysis of full frequency and frequency division technology of home theater knowledge base

China Home Theater Network () talked about the topic of speakers, we all know that the mainstream equipment sold in the market can be divided into 2.0 speakers, 2.1 speakers and 5.1 speakers according to the purpose or channel. However, there are many different types of speaker speakers. To really understand the box further, you have to start with more detailed things, such as acoustics, which can be classified according to frequency division. Today, Xiaobian will talk about full frequency. Differences and applications with crossover technology:

How much difference between the two genres? Take you to understand the full frequency and crossover

Perhaps many people think that only enthusiasts need to have a deeper understanding of this knowledge, and as a general consumer, we don't need to know so much. But what we can't ignore is that people's material level is now common. It has been improved, more and more people know how to improve their taste and enjoy life. If you need to buy a good speaker to be arty, then the little knowledge that seems to have nothing to do with your life will change. It's especially important. When you buy a product, you know more about the doorway, so you won't be fooled by the business.

We know that the appearance of the speaker looks simple, but the structure of the inner speaker is not simple, but it is precisely because of these complex unit structures, and they are arranged reasonably to create a sound-resistant sound texture. Today we want to be with everyone. Together they are talking about the speakers inside the speakers. Because of the difference, they create different genres of speakers. They are the most important factors affecting the sound and sound quality of the speakers. How much mystery is, let us find out.

The speakers in the speakers are commonly called horns. They are mainly divided into two categories: full-range horns and crossover horns. First of all, let's talk about full-range horns. The full-frequency name refers to the wide range of frequencies and wide coverage. The previous full-range horns cover The frequency range is 200-10000Hz. In recent years, with the continuous improvement of acoustic technology, the general full-range speakers can reach the frequency range of 50-25000Hz, and the low frequencies of some speakers can dive to 30Hz.

The frequency range that we can hear from human ears is 20-20,000 Hz. The full-range speaker can basically cover the sound of all frequency ranges that can be heard by the human ear, but unfortunately, the full-range speakers on the market today, though. It is full frequency. In fact, most of its frequency is concentrated in the middle frequency range. The performance of the subwoofer and treble is slightly weaker, so the sound heard is relatively flat, and the stereoscopic effect is not so strong.

Although the full-range horn does not seem to be so full-range, this weakness can also contribute to its advantage. Because of its strong performance in the mid-frequency stage, the sounds of people are mostly dominated by the intermediate frequency. Therefore, the full-range speaker Very suitable for listening to human voice, and the distortion rate of the ear is low, the performance of the human voice is quite full and natural. In addition, it has only one speaker, in addition to the uniform performance of the sound in each frequency band, as the point source, its phase is also More accurate, and the cost is not so high.

Next, let's talk about the crossover speaker. The crossover is literally understood. It knows that its frequency range is phased. In other words, it means that the frequency is more focused. The more common crossover speakers on the market. The built-in is usually a dual-band speaker or a tri-band speaker. Of course, there are some more high-end speakers, and the number of crossover speakers is more.

Why is the frequency of the crossover speaker more focused, in addition to its number of speakers, there is also a frequency divider inside, which can split the audio signal into several parts, take the three-way frequency For the speaker, this crossover can deliver the bass part to the low-pitched woofer. The mid-range is sent to the mid-range speaker, and the treble is sent to the tweeter. In this way, each speaker will perform its own duties and will each have its own The advantage is that it can make the extension of the high and low sound wider, so it can usually cover a wider frequency range than the full-range speaker.
