amplifiers的音標是["?mpl?fa??(r)z]，意思是“放大器；放大裝置；放大機”。基本翻譯為“放大器；放大裝置；擴音器”。速記技巧為：可以將其中的“ampl”聯想為“ample”（充足的），幫助記憶。

Amplifiers的英文詞源是拉丁語amplificare，意為“放大”。Amplifiers的變化形式有amplitude（振幅）、amplification（放大）、amplifier（放大器）等。相關單詞有：signal amplifier（信號放大器）、audio amplifier（音頻放大器）、voltage amplifier（電壓放大器）等。這些放大器在電子設備中廣泛應用，用于增強信號、音頻和電壓強度，以提高設備的性能和可靠性。

例如，signal amplifier用于增強微弱的信號電平，使其更容易被接收和處理；audio amplifier則用于增強音頻信號，以提高音質和音量。這些放大器在現代電子設備中起著至關重要的作用，推動了通信、音頻和視頻技術的發展。

英文小作文：

I am a music lover and often listen to music with an amplifier. The amplifier can make the music sound more beautiful and clear, which brings me a wonderful listening experience. I also know that amplifiers have different types and specifications, which can affect the sound quality to some extent. Therefore, I always choose a high-quality amplifier to enjoy my favorite music. In addition, amplifiers are also used in other fields, such as communication systems and scientific experiments, where they play an important role in amplifying signals and data. I believe that amplifiers will continue to play an increasingly important role in our lives.
