近幾年來聲波懸浮技術被廣泛地應用，聲波懸浮技術能以非接觸的方式來夾持微小的物體，包含液體、固體及都可以被懸浮駐，並且具有不受懸浮物材質與形狀限制的特性，故聲波懸浮的應用是相當地廣泛。
本研究使用兩組規格相同超聲波換能器和可移動的反射端平面來建置二維聲波懸浮系統，透過超聲波換能器與反射器之間產生駐波來懸浮物體。其中，超聲波換能器與反射器的距離須符合聲波的半波長，如此才能產生駐波將物體懸浮。本研究藉由兩對超聲波換能器與反射端的之間的距離改變，進而改變駐波節點的位置，進而達到讓懸浮物可以進行二維的平面移動。

In recent years, acoustic levitation technology has been widely applied in various fields. Acoustic levitation technology can be a non-contact way of hold and levitating tiny objects, including liquid and solid. It has no restrictions on the material and shape characteristics of the suspended objects, thus the application of acoustic levitation is quite extensive.

In this research, two sets of the same ultrasonic transducer and movable reflector plane are used to construct a two-dimensional acoustic levitation system. A standing wave was used to suspend the object between the ultrasonic transducer and the reflector. Among them, the distance between the ultrasonic transducer and the reflector must be the half wavelength of the acoustic wave in order to produce the standing wave to suspend the object. In this research, the distance between the two pairs of ultrasonic transducers and the reflector is varied. The varioation of the distance results in the change of the position of the standing wave node, thus the two-dimensional plane movement of the suspended matter is achieved.
