Constant current and constant voltage methods can be used to measure the speaker impedance curve respectively with these two types of amplifiers
這2種類型的功放能夠分別實現對揚聲器阻抗曲線使用恆流法和恆壓法進行測量。Technically, the damping factor is the specified load impedance ( in use, that ' d be the speaker system ) divided by the amplifier ' s output impedance
技術上,阻尼因子就是指定的負載阻抗(實踐中,也就是揚聲器系統)除以放大器的輸出阻抗。Technically, the damping factor is the specified load impedance ( in use, that ' d be the speaker system ) divided by the amplifier ' s [ i ] output impedance [ / i ]
技術上,阻尼因子就是指定的負載阻抗(實踐中,也就是揚聲器系統)除以放大器的輸出阻抗。Also, the actual resistance of a particular speaker system is almost never the same as the rated impedance
額定值只是對揚聲器系統阻抗的一個一般性描述,原因在於不可能製造一個類似於電阻那樣工作的動圈揚聲器系統。Rated impedance of loudspeaker
揚聲器額定阻抗Sometimes they present a capacitive load, sometimes they present an inductive load, sometimes simply resistive, sometimes a combination of these
而且,事實上,揚聲器系統的實際電阻從來沒有等同於它的額定阻抗。Use speakers with an impedance of 4 to 8 ohms, and with adequate power handling capacities to avoid its damage
使用4到8阻抗的揚聲器,並有足夠的電源處理容量以防損壞。Plus, everything else affects the impedance : the speaker wire, the connections, contributions from crossover circuits inside the speaker, corrosion, fuses and circuit breakers, loading by changing a ported cabinet when you plug or unplug a port insert, condition of the speaker assembly ( like the foam surrounds of a woofer, or the condition of the ferromagnetic fluid of some tweeters ), the cabinet seals, etc
另外,還有其他東西會影響到揚聲器的阻抗:喇叭線,接線柱,內部分頻線路,部件的腐蝕情況,保險絲或斷路器,箱線頭子和接線柱之間產生的負載,揚聲器組裝時的生產環境,箱體的密封情況,等等。One of the things about amplifiers that affects how they can drive a speaker system is the amplifier ' s output impedance
輸出阻抗是能夠影響放大器如何推動揚聲器系統工作的諸多因素之一。Two types of power amplifier for measuring speaker impedance curve were analysed
摘要分析了2種應用於測量揚聲器阻抗曲線的功率放大器。Transistor hi - fi power amplifier, the output impedance is low, can actuate the speaker well
高速晶體管hi - fi功率放大器,輸出阻抗低,能更好地驅動揚聲器。One of the things about amplifiers that affects how they can drive a speaker system is the amplifier ' s [ b ] output impedance [ / b ]
輸出阻抗是能夠影響放大器如何推動揚聲器系統工作的諸多因素之一。The lower it is, the better the amplifier can present needed current to the speaker system, assuming that in other ways ( such as frequency response ) the amplifier performs well
假如其他因素對放大器的工作狀態沒有影響的話,輸出阻抗越低,放大器就能夠更好地為揚聲器系統提供所需的電流。If the speaker needs more current ( its overall impedance drops ) then a lower amplifier output impedance will allow that current to be drawn out of the amplifier without causing much of a change in the applied voltage - and that means less distortion
如果揚聲器需要更大電流(揚聲器的整體阻抗降低) ,那麼一個低輸出阻抗的放大器可以容許在輸出相應電流的同時,所施加的電壓變化更小,這也意味著失真更小。If the speaker needs more current ( its overall impedance drops ) then a lower amplifier output impedance will allow that current to be drawn out of the amplifier without causing much of a change in the applied voltage - and that means [ i ] less [ / i ] distortion
如果揚聲器需要更大電流(揚聲器的整體阻抗降低) ,那麼一個低輸出阻抗的放大器可以容許在輸出相應電流的同時,所施加的電壓變化更小,這也意味著失真更小。The influences brought from the different measuring conditions on the frequency response curve and impedance curve are introduced
