Abstract

According to one embodiment, an ultrasonic device includes an ultrasonic transmitter. The ultrasonic transmitter includes a first element, a second element, and a driver. The first element is flexing-vibratable at a first resonant frequency. The second element is flexing-vibratable at a second resonant frequency different from the first resonant frequency. The driver is configured to supply a first electrical signal to the first element and to supply a second electrical signal to the second element. The first electrical signal includes a first signal having the first resonant frequency. The second electrical signal includes a second signal having the second resonant frequency.
