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 the corresponding power amplifiers to drive the 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. Here, I will only focus on a few aspects that you value or often feel confused about.

Our acoustics scientists' research on electroacoustics and the continuous development of electroacoustic equipment and technology aim to reproduce various sound sources as realistically as possible. Of course, it is impossible to reproduce the unique sounds of nature using current electroacoustic technology. As is well known, the frequency range of sound is from 20Hz to 20000Hz. Currently, most front-end audio processing devices can reach this frequency range. However, the current speaker has become a bottleneck. It is very difficult to use one or several simple speakers to produce sound in a wide frequency range of 20HZ-2000Hz, as the effective range of operating frequencies for individual speakers 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 a sound system that is close to the true sound frequency (20HZ-2000Hz). Of course, the components and parameters of different speakers in the audio signal distributor 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 principles and ideas are the same.
