The speaker divider can separate the frequency of the sound signal, distinguish the sound signals in different frequency bands, and then amplify them to the speakers in the corresponding high and low frequency bands to achieve the effect of different sound quality.

About the function of loudspeaker divider

Principle of loudspeaker divider:

From the working principle, the frequency divider is a filter network composed of capacitors and inductance coils. The treble channel only allows high-frequency signals to pass through and blocks low-frequency signals; The bass channel is just the opposite, allowing only the bass to pass and blocking high-frequency signals; The mid-range channel is a band-pass filter. Except that the frequency between one low, one high and two frequency dividers can pass through, both the high frequency component and the low frequency component will be blocked.

It seems simple, but in the frequency divider used in practice, in order to balance the difference in flexibility between upper and lower voice units, manufacturers need to participate in attenuation resistors of different sizes or impedance compensation networks composed of resistors and capacitors according to different conditions. Different designs and consumption processes naturally make the frequency divider, a seemingly inconspicuous element, have different effects in the speaker. These details are what all HIFI equipment must pursue, which is also the fundamental difference between HIFI and ordinary civil equipment.

Function of loudspeaker divider:

When playing music, due to the limitation of the capacity and structure of the loudspeaker unit itself, it is difficult to cover all the frequency bands with only one loudspeaker. If the full frequency band signal is directly sent to the high, middle and low frequency units without distribution, the local "redundant signal" outside the unit frequency response range will have a negative impact on the signal restoration within the normal frequency band, which may damage the high and middle tone units. For this reason, designers must divide the audio frequency band into several segments, and stop playing with different loudspeakers in different bands. This is the origin and function of frequency divider.

The frequency divider is the "brain" in the sound box, which is crucial to the sound quality. The music signal output by the power amplifier must be processed by each filter element in the fire frequency device to let the signal of specific frequency of each unit pass through. It is necessary to scientifically, reasonably and rigorously design the frequency divider of the speaker, so as to effectively modify the different characteristics of the speaker unit, optimize the combination, make each unit develop its strengths and circumvent its weaknesses, give full play to its potential, make the frequency response of each frequency band become smooth, and the sound image phase is accurate, so as to make the music played by high, medium and low frequencies clear, synchronized, clear, warm, broad and natural sound quality.
