Transistor impedance transformer

The utility model discloses a transistor impedance transformer which comprises a single-end input audio power amplifier. The utility model is characterized in that: the input terminal of the single-end input audio power amplifier bridges over ground with a pull-down inductance (L). The power amplifier made according to the technical proposal of the utility model has a dynamic loudspeaker ranging from two to sixteen Ohms in free mating with good sound reducibility, clear and vigorous tone quality. 本实用新型公开一种晶体管阻抗变换器，该阻抗变换器包括单端输入音频功率放大器，其特征在于单端输入音频功率放大器的输入端对地跨接一下拉电感(L)。利用本实施所述的技术方案制作的功放，2～16欧电动扬声器可自由匹配，而且声音还原性好，音质清晰、浑厚。
