Abstract: In an electro-acoustic transducer 100 which is an oscillator device, a flat piezoelectric film 120 that moves expansively and contractively through the application of an electric field is disposed on at least one surface of a flat elastic member 110 in which a plurality of holes 111 penetrate a principal surface thereof. Since the stiffness of the elastic member 110 is adjusted by the holes 111, the stiffness impedance with respect to the piezoelectric film 120 can be matched optimally. Thus, it is possible to suppress the amount of vibration displacement and to complement the conversion efficiency of the piezoelectric film 120.

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: In an electro-acoustic transducer 100 which is an oscillator device, center positions of principal surfaces of piezoelectric elements 130 that are positioned on both surfaces of an elastic member 120 are different from each other. As such, since the two piezoelectric elements 130 are disposed asymmetrically on the upper and lower sides in the electro-acoustic transducer 100, it is possible to prevent vibrations of reversed phases at the time of divided vibration in which the reversed phases overlap with each other. In other words, since it is possible to prevent the generation of sound waves due to the vibration of local reversed phases, the sound pressure level can be improved.

Abstract translation: 在作为振荡器装置的电声换能器100中，位于弹性构件120的两个表面上的压电元件130的主表面的中心位置彼此不同。 因此，由于两个压电元件130在电声换能器100中的上侧和下侧不对称地设置，所以可以防止在反相相互重叠的分离振动时的反相振动 。 换句话说，由于可以防止由于局部反相的振动引起的声波的产生，所以可以提高声压级。
