amplifiers

amplifiers的音标是["æmplɪfaɪə(r)z]，意思是“放大器；放大装置；放大机”。基本翻译为“放大器；放大装置；扩音器”。速记技巧为：可以将其中的“ampl”联想为“ample”（充足的），帮助记忆。

Amplifiers的英文词源是拉丁语amplificare，意为“放大”。Amplifiers的变化形式有amplitude（振幅）、amplification（放大）、amplifier（放大器）等。相关单词有：signal amplifier（信号放大器）、audio amplifier（音频放大器）、voltage amplifier（电压放大器）等。这些放大器在电子设备中广泛应用，用于增强信号、音频和电压强度，以提高设备的性能和可靠性。

例如，signal amplifier用于增强微弱的信号电平，使其更容易被接收和处理；audio amplifier则用于增强音频信号，以提高音质和音量。这些放大器在现代电子设备中起着至关重要的作用，推动了通信、音频和视频技术的发展。
