The benefits derived from the development of acoustic transistors which act as switches or amplifiers have been reported in the literature. Here we propose a model of acoustic switch. We theoretically demonstrate that the device works: the input signal is totally restored at the output when the switch is on whereas the output signal nulls when the switch is off. The switch, on or off, depends on a secondary acoustic field capable to manipulate the main acoustic field. The model relies on the attenuation effect of many oscillating bubbles on the main travelling wave in the liquid, as well as on the capacity of the secondary acoustic wave to move the bubbles. This model evidences the concept of acoustic switch (transistor) with 100% efficiency.
文献中报道了声晶体管作为开关或放大器的开发所带来的好处。在这里，我们提出了一种声开关的模型。我们从理论上证明了该器件的工作原理：当开关打开时，输入信号在输出端完全恢复，而当开关关闭时，输出信号为零。开关的开或关取决于一个能够操纵主声场的次级声场。该模型依赖于许多在液体中主行波上振荡的气泡对主行波的衰减效应，以及次级声波移动气泡的能力。该模型证明了具有 100%效率的声开关（晶体管）的概念。
