In an audio frequency divider system, a frequency divider generally refers to an audio peripheral device that can divide the audio signal in the 20Hz-2000Hz frequency band into several suitable and different frequency bands, and then enter the corresponding power amplifiers to drive the corresponding speakers. Because it is an electronic device used 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 some aspects that you value but often feel confused about.

1、 Why use an electronic frequency divider

Our acousticians' research in the field of electroacoustics and the continuous development of electroacoustic equipment and technology aim to reproduce the sound source as truthfully as possible. Of course, it is impossible to reproduce strange natural sounds with current electroacoustic technology. As is well known, the frequency range of sound is between 20Hz and 20000Hz. Currently, most front-end audio processing devices can achieve such a wide frequency range. However, current speakers have become a bottleneck. It is very difficult to generate sound within a wide frequency range of 20Hz to 2000Hz using one or several simple speakers, as the effective operating frequency range of the speakers is not very wide. Considering this, electroacoustic engineers have designed speakers that operate in different frequency bands, such as:

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

2. Low to mid range 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, different speaker components and parameters are different. I take the triple system as an example. In fact, there are other systems, such as two or four frequency dividers. In addition, due to the different speakers used in different audio systems, the working frequency of these speakers cannot be fixed, but the general principle and idea are the same.
