In this paper, a tactile display using elastic waves in a 'tapered membrane'(a membrane whose width decreases gradually) is proposed. When an elastic wave is input to the tapered membrane, there exists a boundary between a vibrating area and a non-vibrating area. The boundary is called 'turning point', and the position of the turning point is controlled by the frequency of the wave. It was reported that a surface of a vibrating object with uitrasonic frequency feels smooth by squeeze effect. Thus, in the tapered membrane, the boundary between smooth and frictional areas can be moved by the frequency of the wave. In an experimental device employing a brass plate vibrated by a Langevin ultrasonic vibrator, these basic phenomena are confirmed.
