In the speaker, there is a very inconspicuous part, saying that it is inconspicuous because it can't be found on the surface of the speaker. Generally, except for those who want to know more about the speaker, almost no one pays attention to its existence. . The speaker is out of it, and it can't work at all. It is the crossover . Let's take a look at the role of the crossover with Xiaobian!

1. The role of the divider - an introduction

The frequency divider is to distinguish the sound signals of different frequency bands, respectively, for amplification, and then send them to the speakers of the corresponding frequency bands for reproduction. In high-quality sound reproduction, electronic frequency division processing is required. It can process the frequency of the input signal so that the frequency of the output signal satisfies the correlation of the circuit. The frequency divider is mainly divided into two categories: analog frequency divider and digital frequency divider.

In a speaker system, people refer to the box, frequency dividing circuit, and speaker unit as the three major parts of the speaker system, and the frequency divider is the "brain" in the speaker. The frequency dividing circuit can restore the speaker system with high quality. Electroacoustic signals play an extremely important role. Especially in the middle and high frequency parts, the role played by the frequency dividing circuit is more obvious. Let's talk about the specific role of the divider.

2. The role of the frequency divider - basic frequency division

Regardless of the type of electronic crossover, the main functions and tasks are of course divided. Because there are many types of speakers, what kind of sinister and multi-frequency electronic crossovers should be used in the system, and the electronic frequency dividers are usually divided by 2, 3, and 4 Equally divided, over 4 is too complicated and meaningless. The frequency divider can reasonably perform power distribution of each unit so that the units have an appropriate phase relationship to reduce the acoustic interference distortion of each unit during operation.

3. The role of the crossover - protect the speaker

We know that the operating frequency of different speakers is different. Generally speaking, the larger the diameter of the speaker, the better the low frequency characteristics and the lower the frequency dive. The electronic crossover can provide the optimal operating frequency required by different speakers to compensate for the acoustic defects of the unit in a certain frequency band, so that various speakers can work more reasonably and safely. Therefore, in addition to the crossover task, the electronic crossover has more important functions: the protection of the speaker device.

4. The role of the divider - increase the level of sound

If there are many different types of speakers in an audio system, and there is no electronic crossover, there will be a lot of overlapping and repeating parts between different speakers. The sound interference will become very serious and the sound will change. It is ambiguous. If the audio system uses an electronic crossover to make a reasonable crossover, so that different speakers are in the best working condition, the sound frequency range between different speakers will be almost never repeated, and the interference of sound waves will be reduced. The sound will become extraordinarily clear, and the sound will be better and more layered!

The role of the crossover is introduced. Here are a few crossovers for the children's shoes.
