1. A piezoelectric element, comprising:
- a piezoelectric body having a mounting surface and at least one other surface;
a plurality of first internal electrodes and a plurality of second internal electrodes alternately arranged at given intervals inside the piezoelectric body;
a first terminal electrically connected to the plurality of first internal electrodes and formed on the at least one other surface of the piezoelectric body;
a second terminal electrically connected to the plurality of second internal electrodes and formed on the at least one other surface;
a reference electrode formed on the mounting surface of the piezoelectric body; and
a third terminal electrically connected to the reference electrode and formed on the at least one other surface;
wherein the reference electrode is maintained at a predefined DC potential.

Abstract
Provided is an electronic device including: a base; a panel; a support for supporting the panel with respect to the base; and a vibrator for causing the panel to vibrate at a given frequency. The support includes a first region located at a part corresponding to a node of vibration of the panel, and a second region located at a part other than the node of the vibration of the panel. The support has a rigidity that is smaller in the first region than in the second region.
