[The function of the frequency divider] The frequency divider is also called the sound divider board,which is often installed in the speaker shell;its function is to divide the total frequency signal from the power amplifier,divide the treble signal to the tweeter unit,and divide the bass signal to the woofer unit.Just like the big and small lanes and sidewalks on a major highway,they are separated so as not to confuse people and vehicles. Since the frequency divider is installed in the speaker shell and cannot be seen from the outside,many finished speakers are saved by the manufacturer,or a very low-end frequency divider is used,or one or two capacitors are used instead.If the speaker does not have a frequency divider,the sound will of course be messy.A professional frequency divider will make the sound quality of the speaker much clearer,and the high and low levels will be clearly distinguished the treble not only makes it clear,but also strictly prevents the low frequency signal from entering,protecting the tweeter unit.Burn out less often.To increase the strength of the bass,the woofer can be disconnected from the frequency divider,although it will not be ,but due to the entry of high frequencies,the bass works in the piston state,and the strength is not as good as the effect of the frequency divider. How to identify the good or bad of the frequency divider: In addition to the reasonable circuit design,the material used is that the larger the copper wire of the coil,the better,and the oxygen-free copper wire should be used for winding;the higher the withstand voltage of the capacitor,the better,and the non-inductive copper wire should be used.capacitor. Crossover model: H-883,it is a treble + midrange + bass three-way three-way divider.Using standard 12dB second-order design circuit,it belongs to HI-FI high-fidelity type,the material is
