speaker impedance 中文意思是什麼

speaker impedance 解釋
揚聲器阻抗
  • speaker : n 1 說話人；演說者；雄辯家。2 廣播員。3 擴音器，揚聲器；喇叭，話筒。4 〈S 〉英國下議院、美國眾議...
  • impedance : n. 【物理學】阻抗。 acoustic impedance聲阻抗。
  1. 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。
  2. 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。
  3. 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。
  4. 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。
  5. 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。
  6. 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。
  7. 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。
  8. 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。
  9. 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。
  10. 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。
  11. 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。
