Abstract
In an oscillator (), a plurality of piezoelectric vibrators (to) supported by vibrator support mechanisms () individually output highly directional sound waves. The plurality of piezoelectric vibrators (to) is formed by dividing a laminated body of an elastic member and a piezoelectric substance by the vibrator support mechanisms (). Since it is not necessary to arrange the plurality of piezoelectric vibrators in a matrix, the entirety of a device can be small-sized. A sound deflection unit that deflects a sound wave which is output by at least one of the piezoelectric vibrators may be further included.
