Abstract
An ultrasonic generator has a speaker element having a first resonance frequency and a speaker element having a second resonance frequency. The first resonance frequency and the second resonance frequency are adjacent resonance frequencies in the speaker. The distance between the elements is set so that the sound from the first speaker element and the sound from the second speaker element have a predetermined relationship at a target position. The target position is two or more positions on the object located in the target space. A predetermined relationship is a relationship in which a sound from the first speaker element and a sound from the second speaker element strengthen each other at an intermediate frequency between the first resonance frequency and the second resonance frequency.
