In audio systems, a frequency divider generally refers to an audio peripheral device that can divide audio signals in the 20HZ-20000Hz frequency band into several suitable different frequency bands, and then feed them into corresponding power amplifiers to drive corresponding speakers. Due to its use as an electronic device for processing and distributing audio signals, we often refer to it as an electronic frequency divider. I won't go into more detail about the functions and working principles of electronic frequency dividers.

Our acoustics experts aim to reproduce various sound sources as realistically as possible in their research on electroacoustics and the continuous development of electroacoustic equipment and technology. Of course, with current electroacoustic technology, it is impossible to reproduce the strange sounds of nature. As is well known, the frequency range of sound ranges from 20Hz to 20000Hz. Currently, most front-end audio processing devices can reach this frequency range. However, current speakers have become a bottleneck. It is very difficult to generate sound in a wide frequency range of 20HZ-2000Hz using one or several simple speakers, as the effective operating frequency range of a single speaker is not very wide now. Considering this, electroacoustic engineers have designed speakers that operate in different frequency bands, such as:

1. Bass speaker: Let it operate in the frequency range of around 30-200Hz.

2. Mid low speaker: Let it operate in the frequency range of around 200-2000Hz.

3. High pitched speaker: Let it operate in the frequency range of around 2000-20000Hz. In this way, we can use different types of speakers operating in different frequency bands to configure sound systems that are close to the true sound frequency (20HZ-2000Hz). Of course, the components and parameters of different speakers are different. I take the three-point system as an example. Actually, there are other systems, such as binary or quad frequency systems. In addition, due to the different speakers used in different audio systems, the operating frequency of these speakers cannot be fixed, but the general principle and idea are the same.

The following problem is how to flexibly allocate audio to different types of speakers working in different frequency bands. In order to solve this problem, electronic frequency dividers have emerged, which can provide suitable frequency bands according to the needs of different speaker operating frequencies,
