In the speaker, there is a humble part that says that it is inconspicuous because it cannot be found on the surface of the speaker. Generally, there is almost no one who pays attention to its existence except those who want to understand the speaker. And the speaker is away from it and cannot work at all. It is a frequency division.

The frequency splitter is the "brain" in the speaker. It is important to the quality of the sound quality. Then send it to the corresponding high, medium, and bass speakers to replacement. The frequency division refers to distinguishing the sound signals of different frequency bands, enlarged them, and then sent to the speakers in the corresponding frequency band for replacement. When the high -quality sound is replaced, electronic division is needed. Whether it is a treble unit or a bass unit, their own frequency ring curves are not flat, and the treble and bass speakers will be attenuated at both ends. In this way, low audio will be low. The part of the sound of the sound may be overlapped or even staggered with the lower limit attenitive part of the treble sound, causing the frequency band to be overlapped and the straight curve cannot be formed, so the sound of this will not be a good sound quality.

The role of a frequency division is to be responsible for completing this frequency ringing combination between each speaker to achieve better results. The frequency division dealer the music signal output by the amplifier is processed by the original filtering to allow the specific frequency signals of each unit to pass. To put it simply, the original signal is divided into several bands. The frequency band is assigned to it to achieve the coordinated work of multi -speakers.
