現(xiàn)在很多人都有條件在房子里置辦上家庭影院音箱，但不要覺得這是很簡單的事情，要注意的事項很多，比如說搭配功放問題。下面我們就一起來分析分析吧。
A lot of people have condition to buy box of sound of family cinema on doing in the house now, but do not feel this is very simple thing, the item that should notice is very much, for example tie-in result puts a problem. Let's analyze it together.
如果揚聲器的額定阻抗大于功放的額定輸出阻抗，功放的實際輸出功率就會小于額定輸出功率，導致聲音不完整，音量低。如果揚聲器的額定阻抗小于功能的額定輸出阻抗，實際功率會增加，會造成失真，放大器有過載的危險。
If the rated impedance of loudspeaker is greater than the rated output impedance of result put, the actual output power of result put can be less than rated output power, bring about sound incomplete, volume is low. If the rated impedance of the speaker is less than the rated output impedance of the function, the actual power will increase, resulting in distortion and a danger of overloading the amplifier.
功放電路應連接的額定負載阻抗值是制造商設(shè)計功放的基本參數(shù)。晶體管功放屬于低阻輸出電路，而電子管功放屬于高阻輸出電路，對喇叭的阻抗值要求非常嚴格。
The power amplifier circuit should be connected to the rated load impedance value is the manufacturer's design of the basic parameters of the power amplifier. Transistor power amplifier belongs to low resistance output circuit, and electronic tube power amplifier belongs to high resistance output circuit, the impedance value of the horn is very strict requirements.
如果揚聲器的阻抗符合匹配要求，并且承受功率小于功放功率，則驅(qū)動功率充足，聽起來很舒服。這就是人們常說的功放的儲備功率一定要大，才能充分表現(xiàn)出音樂的全部內(nèi)涵，尤其是音樂的低頻部分，更加生動有力。這是一場很好的比賽。
If the speaker's impedance matches and the power is less than the power of the amplifier, the drive power is sufficient and sounds comfortable. The reserve power that this is the result that people often says puts must be big, the total connotation that ability shows music adequately, especially the low frequency part of music, more vivid and powerful. It was a good game.
所謂阻尼，是衡量功放輸出級對揚聲器阻尼的內(nèi)阻的指標。如果阻尼系數(shù)太高，揚聲器發(fā)出的聲音會比較干澀，不圓潤；如果太低，聲音會粘在一起。
Alleged damped, it is the index that measures result to put output level to the inside resistance of loudhailer damped. If the damping coefficient is too high, the sound from the speaker will be dry and not round; If it's too low, the sounds stick together.
有的音箱需要較高的阻尼系數(shù)來控制本機的動作，但如果配備阻尼系數(shù)不足的功放，會使本機失去控制，造成過多的共振和音頻損失；相反，如果一對不需要高阻尼系數(shù)的揚聲器配備高阻尼功率放大器。由于單元的高阻尼控制，聲音會變得堅實，音尾會很短。
Some speakers need higher damping coefficient to control the action of the machine, but if equipped with insufficient damping coefficient of the power amplifier, the machine will lose control, resulting in too much resonance and audio loss; Conversely, if a pair of speakers that do not require a high damping factor are equipped with a high damping power amplifier. Because of the unit's high damping control, the sound is solid and the end is extremely short.
總的來說，在計劃打造
家庭影院音箱系統(tǒng)時，應該看看自己平時的使用習慣。在功放選擇方面，可以根據(jù)看電影和聽音樂的比例來選擇搭配。如果看電影的需求比較多，功放可以考慮一些影院質(zhì)量比較好的企業(yè)，如果聽音樂的需求比較多，可以考慮音樂質(zhì)量比較好的企業(yè)。
In general, when planning to build a home theater sound system, you should look at your usual use habits. In terms of power amplifier selection, you can choose collocation according to the proportion of watching movies and listening to music. If the demand for watching movies is more, the power amplifier can consider some theaters with better quality brands, if the demand for listening to music is more, you can consider the brand with better music quality.
How does the home theater speaker do when collocation with the result amplifier? Aiming at this problem, we have made in the above explanation, if you still want more, try to look on the web site, http://www.gulfbaader.com.
