In the audio system, the frequency divider generally refers to an audio peripheral device, which can divide the audio signal in the 20HZ-20000Hz frequency band into several suitable different frequency bands, and then feed it into the corresponding power amplifier to drive the corresponding speaker. Since it is an electronic device used to process and distribute audio signals, we often call it an electronic crossover. I won't say much about the detailed functions and working principles of the electronic frequency divider.

The goal of our acousticians' research into electroacoustics and the continuous development of electroacoustic equipment and technology is to reproduce a variety of sound sources as faithfully as possible. Of course, with the current electro-acoustic technology, it is impossible to reproduce the strange sounds of nature. As we all know, the frequency range of sound is from 20Hz to 20,000Hz. Currently, most front-end audio processing equipment can reach this frequency range. However, current speakers have become a bottleneck. Use one or a few simple speakers to generate a frequency as wide as 20Hz-2000Hz

t is very difficult to produce sound in the frequency range, because the effective operating frequency range of a single speaker is not very wide. With this in mind, electro-acoustic engineers design speakers that work in different frequency bands, such as:

1. Woofer: Let it work in the frequency range of about 30-200Hz.

2. Medium and low speakers: let it work in the frequency range of about 200-2000Hz.

3. Tweeter: let it work in the frequency range of about 2000-20000Hz. In this way, we can use different types of speakers working in different frequency bands to configure a sound system that is close to the real sound frequency (20HZ-2000Hz). Of course, the components and parameters of different speakers are different. I use the three-point system as an example. There are actually other systems, such as two-way or four-way systems. In addition, due to the different speakers used in different audio systems, the operating frequencies of these speakers cannot be fixed, but the general principles and ideas are the same. Electronic crossover

The question that follows is how to flexibly distribute audio to different types of speakers operating in different frequency bands. In order to solve this problem, electronic crossovers came into being, which can provide suitable frequency bands according to the needs of different speaker operating frequencies, such as:

1. We can use the electronic crossover to send the high frequency signal to the tweeter through the power amplifier. Electronic crossover

2. An electronic frequency divider can be used to transmit the intermediate frequency signal to the medium speaker through the power amplifier.

3. The low frequency signal can be sent to the woofer through the power amplifier using the electronic frequency divider.
