摘要： 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.

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： 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.
