In this paper, we present a new method for beam width control of transducer array using two-layered piezoelectric transducers of which electroacoustic efficiency can be controlled by a capacitor. The measured result for beam width control of the transducer array shows good agreement with the simulation result. It is confirmed that the beam width of the transducer array is easily controlled by varying the second harmonic generation efficiency of each element.
