摘要： 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.

摘要： A mobile phone (100) detects at least a direction of an utterance position of a user from the voice input to a plurality of microphones (121, 122) and controls an output direction of a voice out of a speaker unit (110) to match the detected utterance position. Accordingly, it is possible to provide sound with sufficient volume only for a specific user without causing noise in the neighborhood. The microphones may form a matrix together with piezoelectric vibrators that form a speaker unit, or may be formed separately from the speaker unit.
