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.

Abstract: 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.

Abstract: Provided is an electronic device including a modulation unit (22) that modulates a sound signal to a modulation wave for a parametric speaker; an oscillator (12) to which the modulation wave is input; an equalizer (26) that corrects a frequency characteristic of a sound wave that is demodulated by the modulation wave; and a control unit (20) that selects a carrier frequency of the modulation wave and changes setting of the equalizer (26) on the basis of the selected carrier frequency. Thus, it is possible to provide the electronic device capable of correcting the frequency characteristic of the sound wave that is demodulated, for each carrier frequency of the modulation wave.

Abstract: An oscillation device (electro-acoustic transducer (100)) includes an oscillation element (110) that has a vibrating member (120) and a piezoelectric element (111) that is attached to one surface of the vibrating member (120). The oscillation device includes a sheet-shaped waterproof member (140) that is constituted by a waterproof material. The oscillation device includes a frame-shaped supporting member (130) that holds an outer peripheral portion of the vibrating member (120) and an outer peripheral portion of the waterproof member (140) so that the waterproof member (140) and the oscillation element (110) face each other. The oscillation device includes a connection member (150) that partially connects mutual opposed surfaces of the oscillation element (110) and the waterproof member (140).
