| Abstract(in English) | Ultrasonic speakers can be radiated sound wave linearly by using ultrasonic waves. A typical ultrasonic speaker has been difficult to adjust the position of the radiated sound after installation of speaker system in the field. Therefore, the purpose of this study is to control the transmission direction at the ultrasonic speaker by applying the principle of the phase inverse transducer used. By finding the frequency and directional characteristics of the radiated sound field the direction control of projecting wave from ultrasonic speaker constructed by phase inversion element, we investigated the characteristics of ultrasonic speaker using numerical analysis. |
