Home cinema refers to the simulation of a relatively audio-visual projection location in the home. Generally, the audio-visual equipment in a home is usually an integrated television, and all image images come from the television. Home cinema is a set of audio-visual output modules composed of multiple specialized devices. In summary, home theater can be understood by integrating two concepts, namely "Home Theater Standards" and "Playback Systems for Playing Movies in Home Environments"

家庭影院中環(huán)繞音箱指在環(huán)繞聲中，除了聽眾前方“左-中-右”三聲道外，其它的聲道一般都被叫做環(huán)繞聲道，但是在家庭影院7.1以上聲道環(huán)繞聲中，左中和右中聲道不被稱為環(huán)繞聲道。主音箱一般是單個(gè)且體積較大，環(huán)繞音響有兩個(gè)以上，一般主音箱用于主聲場(chǎng)的還原，如電影中人物聲音從主音箱發(fā)聲，而環(huán)境音則又環(huán)繞音箱負(fù)責(zé)。主音箱一般放在前方，環(huán)繞音箱放在后方或左右兩側(cè)。

Surround speakers in home cinemas refer to the sound channels in surround sound, except for the "left center right" three channels in front of the audience, which are generally referred to as surround channels. However, in home cinemas with 7.1 or higher surround sound channels, the left center right middle channels are not referred to as surround channels. The main speaker is usually a single and relatively large volume, with two or more surround speakers. Generally, the main speaker is used for restoring the main sound field, such as in movies where the sound of characters is emitted from the main speaker, while the ambient sound is also handled by the surround speaker. The main speaker is generally placed at the front, while the surround speaker is placed at the rear or on both sides.

01家庭影院KTV音響的選購技巧

Tips for purchasing KTV sound systems in 01 home theaters

家庭影院環(huán)繞音箱與主音箱區(qū)別有以下幾點(diǎn)：

There are several differences between home theater surround speakers and main speakers:

1、一般主箱體比較大，如果是一樣大小的箱子，環(huán)繞有可能是雙向的。如果完全一樣，那就不用區(qū)分了。都可以做前置，或環(huán)繞音箱。好多家庭影院5.1音箱都是完全一樣的5個(gè)音箱，沒有前置音箱和環(huán)繞音箱的區(qū)別。不過，在環(huán)繞音箱系統(tǒng)中需要準(zhǔn)備一個(gè)低音炮。

1. Generally, the main box is relatively large, and if it is of the same size, the surrounding area may be bidirectional. If it's exactly the same, then there's no need to distinguish. Both can be used as front speakers or surround speakers. Many home theater 5.1 speakers have exactly the same 5 speakers, without the difference between front speakers and surround speakers. However, a subwoofer needs to be prepared in the surround speaker system.

2、在外形來看調(diào)換一下是可以的，不過在硬件設(shè)計(jì)和調(diào)音走向方面，主音箱和環(huán)繞音箱還是有不少區(qū)別的，如果進(jìn)行了調(diào)換會(huì)對(duì)環(huán)繞效果產(chǎn)生影響;

2. It is possible to switch the appearance, but there are still many differences between the main speaker and the surround speaker in terms of hardware design and tuning direction. If a switch is made, it will have an impact on the surround effect;

3、在音箱的功率方面，顯然是主音箱的功率更高，而環(huán)繞聲音箱，低音頻率都在70赫茲以上，低音不是很好，而且環(huán)繞聲音箱的功率都在100W以下，因?yàn)榄h(huán)繞聲，是多聲道，功放功率都不大;

3. In terms of speaker power, it is obvious that the power of the main speaker is higher, while the bass frequency of surround sound speakers is above 70 Hz, and the bass is not very good. Moreover, the power of surround sound speakers is below 100W, because surround sound is multi-channel and the power amplifier power is not high;

4、應(yīng)用場(chǎng)景不同：一般主音箱用于主聲場(chǎng)的還原，如電影中人物聲音從主音箱發(fā)聲，而環(huán)境音則由環(huán)繞音箱負(fù)責(zé)。

4. Different application scenarios: Generally, the main speaker is used for restoring the main sound field. For example, in movies, the sound of characters is emitted from the main speaker, while the ambient sound is handled by the surround speaker.

5、擺放位置不同：主音箱一般放在前方，環(huán)繞音箱放在后方或左右兩側(cè)。

5. Different placement positions: The main speaker is generally placed in the front, while the surround speaker is placed in the rear or on both sides.

6、形體區(qū)別：主音箱體積較大，一般是兩個(gè)大小相同的箱體，而環(huán)繞音箱有兩個(gè)以上的箱體，箱體的大小有相同也有不同的組合。好多家庭影院5.1音箱都是完全一樣的5個(gè)音箱，沒有前置音箱和環(huán)繞音箱的區(qū)別，不過，在環(huán)繞音箱系統(tǒng)中需要準(zhǔn)備一個(gè)低音炮。

6. Shape difference: The main speaker has a larger volume, usually consisting of two boxes of the same size, while there are more than two boxes surrounding the speaker. The size of the boxes can be the same or different combinations. Many home theater 5.1 speakers have exactly the same 5 speakers, without the difference between front speakers and surround speakers. However, a subwoofer is required in the surround speaker system.

7、不能調(diào)換：在外形來看調(diào)換一下是可以的，不過在硬件設(shè)計(jì)和調(diào)音走向方面，主音箱和環(huán)繞音箱還是有不少區(qū)別的，如果進(jìn)行了調(diào)換會(huì)對(duì)環(huán)繞效果產(chǎn)生影響。

7. Cannot be swapped: It is possible to switch the appearance, but there are still many differences between the main speaker and the surround speaker in terms of hardware design and tuning direction. If swapped, it will have an impact on the surround effect.

8、功率不同：在音箱的功率方面，顯然是主音箱的功率更高，而環(huán)繞聲音箱，低音頻率都在70赫茲左右，因此環(huán)繞聲音箱的功率都在100W以下，因?yàn)榄h(huán)繞聲是多聲道，功放功率都不大。

8. Power difference: In terms of speaker power, it is obvious that the main speaker has a higher power, while the bass frequency of surround sound speakers is around 70 Hz. Therefore, the power of surround sound speakers is below 100W, because surround sound is multi-channel and the power amplifier power is not high.
