What is 2.1 speaker
2.1 Frequency division design of speakers: If the satellite box speaker unit is designed as a full band speaker, since there is only one speaker, the theoretical playback frequency range is 20Hz~20000Hz, but it is difficult to do in practical application. Some satellite boxes are small in size and speaker diameter, which may lead to insufficient fullness of the middle and low bass. However, most satellite speakers with this design are small in appearance and low in cost.
Another frequency division design is to use the combination of a tweeter and a mid bass speaker on the speakers of the satellite speakers, which can make the low, medium and high parts perform better. However, the satellite boxes of this type of speakers are generally large.
2.1 Sound channel design of speakers. 2.1 The speaker has two independent power amplifier modules, one for stereo and the other for subwoofer. The stereo module is an independent left (L) and right (R) channel power amplifier block, and the subwoofer is a slightly high-power power amplifier block filtered by both left and right channels. Because the bass and bass are jointly filtered, one line in the left and right input channels is disconnected, and the other corresponding speaker will also make a slight sound. This can be used to test the quality of the speaker. You can only connect one left or right audio input line, and listen to the volume of the other satellite speaker is relatively large or small, and the smaller the better. The smaller the bass and bass changes between one input line and two input lines, the smaller the better.
