Frequency divider is a kind of audio equipment which can divide sound signal into several frequency bands. In today's audio technology knowledge, we want to understand with you why the use of frequency divider in professional audio high bass separate speaker.

 

In the professional sound, the treble unit is generally horn speaker, while the bass unit is in the form of direct beam and air flow. Whether it is internal frequency division or external frequency division, the separation of high and low frequency speakers should adopt the scheme of frequency division and playback. The main reasons are as follows:

 

First: the use of frequency divider can make all kinds of speakers work in the most suitable audio segment

 

The use of frequency divider can send high-frequency signal to the high-frequency loudspeaker, low-frequency signal to the bass speaker, high-frequency and low-frequency signals go their own way, as far as possible to make full use of the working frequency band advantages of their respective loudspeakers, so as to ensure that the loudspeakers of different working frequency bands can give full play to their functions and make the sound playing characteristics of each frequency more balanced and consistent.

 

Second, the frequency divider can overcome the cutting distortion caused by the different vibration amplitude of loudspeaker diaphragm in different frequency band

 

If we use a loudspeaker to produce sound in a wide frequency range, it is very difficult to produce sound with very wide amplitude due to the limitation of the mechanical properties of the diaphragm, which will inevitably cause the phenomenon of sound cutting distortion and affect the quality of the reconstructed sound. But if we use frequency divider in audio technology, this phenomenon may be improved.

 

Third: the use of frequency divider in professional audio technology can reduce the sound interference between different loudspeakers in the same speaker

 

The reason why there will be sound interference in the frequency division point and the frequency division cross area is very simple. Because the frequency division attenuation rate of the frequency divider cannot be infinite, in the frequency division cross area, especially in the frequency division point, there will be sound interference at the same time between the high speaker and the bass speaker. Therefore, the higher the frequency divider attenuation rate is, the smaller the frequency division cross area is, and the smaller the sound interference between speakers.
