Abstract:
A vibration device can include a vibration generator including a vibration portion, in which the vibration portion includes a plurality of inorganic portions having piezoelectric characteristics, the plurality of inorganic portions being spaced apart from each other; and an organic portion disposed between at least two inorganic portions among the plurality of inorganic portions, the organic portion having non-piezoelectric characteristics. The organic portion includes a first organic portion and a second organic portion, the first organic portion being disposed between one of the plurality of inorganic portions and the second organic portion. Further, an elastic modulus of the first organic portion is lower than an elastic modulus of the second organic portion.
