Abstract
Provided are a sound generator including a frame body, a vibration body provided to the frame body in a state where a tensile force is applied to the vibration body, and a piezoelectric vibration element provided to the vibration body. In the sound generator, when a first direction and a second direction are directions along a main surface of the vibration body and intersect with each other, the tensile force in the first direction and the tensile force in the second direction are different from each other. A sound generation device and an electronic apparatus including the sound generator are also provided.
