摘要: A second housing 200 is capable of moving in a direction in which the second housing covers one surface of a first housing 100. Oscillating elements of an oscillating element group 400 are arranged in a matrix and oscillate sound waves outward from the one surface of the first housing 100. A control unit controls the plurality of oscillating elements. A sound wave sensor constitutes the same matrix as the plurality of oscillating elements and detects sound waves having a specific wavelength. The detection results of the sound wave sensor are output to the control unit. A frame body holds the plurality of oscillating elements and the sound wave sensor. The control unit oscillates sensor sound waves having a specific wavelength outward from at least one of the oscillating elements. The control unit determines that the second housing 200 covers the one surface of the first housing 100 when the sound wave sensor detects the sound waves having the specific wavelength.

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 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.
摘要翻译: 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。

摘要: An oscillation device includes: a piezoelectric vibrator (110) in which electrode layers (112, 113) are formed over top and bottom surfaces of a piezoelectric layer (111); a vibrating member (120) having at least atop surface to which the piezoelectric vibrator (110) is bonded; and a resin member (130) formed continuously in a circumferential direction over at least the outer side surface of the piezoelectric vibrator (110).
