Black electricity common sense daily new knowledge: the interpretation of the role of audio crossover

A frequency divider is an acoustic device that divides a sound signal into frequency bands. I believe many of my friends don't have a special understanding of this, so today Xiaobian is here to share with you why the professional audio high and low sound split speaker should use the crossover. Help everyone have a clear understanding and understanding.

In professional audio, the tweeter is generally a horn speaker, and the woofer is available in direct and airflow. Regardless of the internal crossover or the external crossover, the high-bass split-type speakers must adopt the scheme of frequency-divided playback. The main reasons are as follows:

First: using a crossover allows all speakers to work in the most suitable audio segment

The frequency divider can be used to send high-frequency signals to the tweeters, and the low-frequency signals are sent to the woofer. The high- and low-frequency signals are used in different ways, and the operating band advantages of the respective speakers are utilized as much as possible to ensure the speakers in different working frequency bands. Give full play to make the playback characteristics of each frequency more balanced.

Second: the use of frequency divider can overcome the cutting distortion caused by the vibration amplitude of the sound speaker diaphragm in different frequency bands.

If we use a single speaker to produce a wide range of frequencies, it is very difficult to have a very wide amplitude of vibration due to the mechanical properties of the diaphragm. This will inevitably cause distortion of the sound and make the sound quality reproducible. Affected. But if we use a crossover in the sound technology, this phenomenon may be improved.

Third: the use of crossovers in professional audio technology can also reduce the sound interference between different speakers in the same speaker

The reason why the frequency interference phenomenon exists in the crossover point and the crossover crossover area is very simple, because the frequency division attenuation rate of the frequency divider cannot be made infinite, in the crossover intersection area, especially at the crossover point, the tweeter and the bass. The speaker will have the sound of the other band at the same time, and the phenomenon of sound interference is inevitable. Therefore, the higher the frequency division attenuation rate of the frequency divider, the smaller the frequency division intersection area, and the smaller the sound interference of the speaker.

Through the above points, I believe that everyone has a general understanding and understanding of the crossover in the professional audio, I hope that the editor and everyone to share the content, so that everyone can understand the sound more, become a true audiophile, let The sound quality of the sound improves the quality of your life.
