To provide a vibration generating device and electronic device capable of presenting a new tactile sensation with a single piezoelectric actuator.SOLUTION: A vibration generating device 100 includes a tactile sensation extending member 103, which is a plate-shaped member having a tactile sensation extending function and a piezoelectric actuator 104. The tactile sensation extending member 103 includes a base having a first main surface and a second main surface opposite to the first main surface and a plurality of protrusions 112, which is a plurality of protrusions protruding from the first main surface, with the vertices of the plurality of protrusions located on a predetermined plane. The piezoelectric actuator 104 is bonded to the second main surface.SELECTED DRAWING: Figure 1 【課題】１つの圧電アクチュエータにより新たな触感を提示することが可能な振動発生装置及び電子機器を提供する。【解決手段】振動発生装置１００は、触覚拡張機能を有する板状部材である触覚拡張部材１０３と、圧電アクチュエータ１０４と、を具備する。触覚拡張部材１０３は、第１の主面と、第１の主面とは反対側の第２の主面を有する基部と、第１の主面から突出する複数の突起であって、複数の突起の頂点が所定の平面上に位置する複数の突起１１２と、を備える。圧電アクチュエータ１０４は、第２の主面に接合されている。【選択図】図１
