Abstract
There are provided an acoustic generator, an acoustic generation apparatus, a portable terminal and an electronic apparatus, which have an improved sound quality. An acoustic generator includes a piezoelectric element having a piezoelectric body; and a vibration plate joined to the piezoelectric body via a joining material, distances between the vibration plate and the piezoelectric body being different. Since this configuration achieves a clear and sharp sound quality, and has an effect of increasing sound pressure, the acoustic generator having an improved sound quality can be achieved.
