Abstract
A method for transmitting an ultrasonic wave is disclosed. The method includes: selecting a first combination of transmission elements from among multiple transmission elements, wherein the first combination of transmission elements includes at least two transmission elements adjacent to each other; and vibrating the transmission surfaces of the first combination of transmission elements in a substantially same phase to transmit the ultrasonic wave with a first directivity. The first directivity is different from a second directivity of the ultrasonic wave transmitted from single transmission element.
