Abstract
A sound generator and sound generation system including the sound generator includes a piezoelectric element of a stack type having a multilayer structure. The piezoelectric element stretches and contracts along a stacking direction generates vibration according to a sound signal. An object, different from the sound generator and from a human body, generates a sound using the vibration and acts as a speaker while in contact with the sound generator.
