Now people’s living standards are getting better and better. People also like to buy some products to make their lives better. Now, people prefer to buy some audio products to improve their taste and quality of life. The highest-selling audio products are really wireless headphones, but the real wireless headphones are still a small thing, and the price is not expensive. Most people still know more about headphones. However, another audio product is the speaker. Compared with headphones, the price of the speaker is relatively expensive, but a good speaker placed at home can also better enhance the quality of life.
It is relatively simple to buy headphones, but for many people, it is a little technical difficulty to buy speakers. What Bluetooth speakers, home theaters, bar speakers, echo walls, etc., just looking at the product name will make people see things in a blur, not to mention the specific parameters. Today, let’s talk about the relatively simple parameters. What is the sound track?
I believe that when you buy speakers, you will see 2.0 channels, 3.1 channels, 5.1 channels, etc. Many people will faint when they see this number. What do so many numbers represent? Is it the same as the version number of the Android system on the mobile phone? For example, a large number means that the new version is advanced, and a small number means that the old version is relatively weak. This idea is half right. The higher the number, the richer the vocal tract, and the better the auditory experience.
Explain from the most common objects around you.
In order to let everyone have a better understanding of the sound track, let’s start with the most common items around us and explain what the sound track is for you most intuitively.
Now smart phones are standard for people. If you don’t have a smart phone in your hand, then I don’t know what to do. In the past few years, everyone’s smart phone can see a row of holes at the bottom of the phone, and the speaker is inside the hole, which is the most common mono speaker. Some mobile phones have a row of holes on the left and right sides of the bottom of the phone. It should be noted that although there are two rows of holes, only one side actually makes noise, and the other half is either a decoration or a mobile phone microphone. The mobile phone designed in this way has Xiaomi 8. Then the above mono is finished, and a single speaker is mono.

As time goes by, technology is developing with each passing day, and smart phones are getting better and better, so dual-speaker mobile phones come into being. Usually, manufacturers will design a speaker at the bottom of the mobile phone and a speaker at the top of the mobile phone, which forms a dual channel, and the listening feeling will be better. If you experience watching video with a dual-channel mobile phone for the first time, you will feel suddenly enlightened. I feel that the mono mobile phone is simply weak. That’s what I am. After I switched from Xiaomi 8 to Samsung S20 Ultra, the sound is simply bad. However, some mobile phone manufacturers have also adopted very ingenious designs, such as the famous Apple, and the iPhone 11 Pro, for example. A mobile phone with a small price of 10,000 yuan is naturally a dual-speaker mobile phone, but Apple cleverly designed the receiver at the top of the mobile phone as an external speaker. This design can be described as killing two birds with one stone. As for why Apple does this, some people say that it can’t fit inside the mobile phone and Apple doesn’t want to make the mobile phone. The disadvantages of this design are also obvious. The sounds at both ends are different. The speaker at the lower part of the mobile phone is better and louder, but the speaker above the handset is thinner. The two-speaker stereo speaker of mobile phone is the most common 2.0 channel.

Let’s talk about the advanced channel version.
The most common mono and 2.0 channels in life are finished. Let’s take a look at the more advanced 2.1 channels, 5.1 channels and 7.1 channels.
Let’s look at it one by one. As mentioned above, 2.0 channel is the left and right two-channel stereo, and the dual speakers on the mobile phone are a good example. So what is 2.1 channel? 2.1 channel is to add a bass speaker on the basis of 2.0 channel dual speakers, which can directly increase the bass effect of this set of audio. The sound channel of 3.1 is based on the sound channel of 2.1, and a center sound channel is added. This loudspeaker is specially responsible for taking charge of human voice, which makes the dialogue between people clearer. The sound channel of 5.1 is based on the sound channel of 3.1, and the surround sound of left rear and right rear is added, which makes the surround effect of sound more obvious. The channel of 7.1 is then increased on the basis of 5.1 channel, and two surround channels are added, so that the surround effect of sound is further increased.
In fact, there is also a 5.1.2 channel. What the hell is this channel? This is actually an advanced layer on the basis of the 5.1 channel. On the basis of the 5.1 channel, two sky channels are added to the ceiling, which can bring you a shocking effect, such as an airplane flying overhead or something flying overhead, and make you feel more immersive. I think it would be very exciting to watch the movie "Decisive Battle of Midway" with a 5.1.2 sound system.

summary
Having said that, I believe that everyone has a certain understanding of the sound track, and I hope it will be helpful for everyone to buy speakers. Generally speaking, the more channels, the more immersive listening experience, the more realistic sound surround effect, and the more channels, the more expensive the sound will be. In a word, if you spend more money, you can enjoy a better sound system. So, everyone, I’m going to try to move bricks. Feel free.
In fact, you can experience 7.1-channel headphones with very little money, such as the 1MORE Spearhead VR H1005 esports headphones, and you can enjoy the virtual surround of 7.1 channels with only 199. This headset can turn on the 7.1 virtual multi-channel surround technology in the software, enhance the three-dimensional sense of ambient sound, and make the stereo surround sound more realistic. Friends who like it can experience the virtual 7.1 channel for a little money.
