What does computer stereo 2 1 and 5 1 mean

It refers to two satellite speakers + 1 subwoofer If there is no subwoofer, it is, as the name suggests, five satellites + 1 subwoofer.

That is, the left and right speakers plus a subwoofer are left, right, center, rear left, rear right, five speakers plus a subwoofer.

.1"Refers to a bass channel synthesized from other channels, and the woofer is generally placed in the front and center position.

It contains the three channels of the front, left, center and right, and the two channels of the left and right in the back, as well as the bass channel, which requires a special sound source to produce a surround effect, such as specially recorded ***, PC games, etc. The results of using the simulation are not good.

It's a standard Dolby surround speaker, with two front and two rear middle (bass), and a center high-midrange combiner.

It's like a standard computer configuration, with one bass in the two left and right speakers.

It's two speakers, one left and one right.

It's two speakers and one more subwoofer,In fact, these two speakers simplify the accent function,Concentrated in the subwoofer。

It's 5 small speakers, called satellite speakers, plus a subwoofer. The satellite speaker is a front left, a front right, a rear left, and a rear right, because the human ear cannot accurately distinguish the direction of the accent, so the subwoofer can be placed more casually.

To put it simply. With five speakers, if placed correctly and the game or movie supports 5 channels, you can hear the sound behind you, such as someone talking behind you, a car behind you ready to overtake you, etc. Two speakers can't create that kind of atmosphere.

However, in general, this kind of use is rarely used.

The speaker has 6 speakers (speakers), including the main speaker, subwoofer, surround and other sound effects, which can only be used with a sound card, otherwise it can only be used as a speaker.

The speaker has 3 speakers (speakers), and if it is used on a sound card, just plug in the green jack.

Hello, these two refer to two systems:

Fingers: a pair of front + a pair of surround + a center + a subwoofer system. Refers to a pair of front-facing + a subwoofer system.

The above is a personal opinion, and I hope it can solve your doubts.

Generally speaking,The speaker of the channel is mainly used for watching movies, pay attention to the sense of presence, reality,The sense of space is very good。 To exaggerate it, if you watch a war movie, the plane takes off, and the direction in which the bullet flies can be realistically restored through the sound channel. (Of course, this also requires the internal sound processing circuit of the power amplifier and a good audio source input as a premise).

The channel is nothing more than a bass channel than the usual stereo sound, so listen to it, if there is no perfect sound processing circuit, it is difficult to achieve a strong sense of space.
