Abstract: In an oscillator (100), a plurality of piezoelectric vibrators (111 to 113) supported by vibrator support mechanisms (120) individually output highly directional sound waves. The plurality of piezoelectric vibrators (111 to 113) is formed by dividing a laminated body of an elastic member and a piezoelectric substance by the vibrator support mechanisms (120). 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.
