In order to give a wide beam width characteristic to a vibrating element, acoustic convex lenses were fabricated and the diverged acoustic field was investigated experimentally. To design the acoustic lenses, an acoustic field estimation method was proposed by using an angular spectrum method. It was confirmed that the estimation of the diverged acoustic field is possible using the suggested method and the acoustic convex lens can achieve the wide beam width characteristics of the vibrator.
