Frequency divider inductor

The inductor of the frequency divider is mostly used in the audio products, which plays an important role in the separation and fidelity of the audio signal, so it is required that such inductors are mostly pure inductors, that is, inductors formed by pure coils, called inductors of the frequency divider. The appearance is often reflected as a hollow coil or wound with a plastic skeleton, so that the inductor's sensing value is the least loss at work, and the loss of its audio signal transmission can be lower.

Inductance coils are usually used as low-pass filtering (filtering high-frequency components) in the speaker divider, and there are generally hollow inductors without iron cores and inductors with iron cores (magnetic cores). The frequency division is related to the inductance, and the lower the frequency division is, the greater the inductance requirement is.

There are three requirements for inductance coils for speakers: one is that the inductance value is accurate; One is its own low DC resistance; One is not easy to produce satiety distortion.

From the working principle, the frequency divider is a filter network composed of capacitors and inductors. The treble channel lets only high frequency signals through and blocks low frequency signals. The bass channel is the opposite, allowing only the bass to pass and blocking the high frequency signals; The midrange channel is a bandpass filter, and both high and low frequencies are blocked, except for the frequencies between one low and one high.
