Abstract: A piezoelectric speaker has a piezoelectric element and vibration plate. The piezoelectric element has a base body with a mounting surface, as well as first and second terminals that are formed on the mounting surface with a distance between them. The vibration plate has a conductive body joined to the piezoelectric element and having a principle surface facing the mounting surface, as well as a first hole with or without a bottom which is formed on the principle surface in a region facing the first terminal to form a space between the body and first terminal. The piezoelectric speaker is capable of preventing the external electrodes of the piezoelectric element from shorting to each other.

Abstract: A multilayer piezoelectric element includes a ceramic body formed by a piezoelectric ceramic, and having first and second end face facing a longitudinal direction, first and second principal faces facing a thickness direction perpendicular to the longitudinal direction. A pair of external electrodes cover the first and second end faces, extend from the first and second end faces onto the first principal face via ridge parts connecting the end faces with the principal faces, and project in the thickness direction on the first principal face. Multiple internal electrodes are stacked inside the ceramic body and are connected alternately to the pair of external electrodes along the thickness direction. A surface electrode is provided on at least one of the first and second principal faces, and connected to the external electrode different from the one to which the internal electrode adjacent in the thickness direction is connected.

Abstract: An electroacoustic transducer includes a dynamic speaker that generates a first acoustic sound, and a piezoelectric speaker that generates a second acoustic sound. The sum of the sound pressures of the first and second acoustic sounds in a crossover frequency range of the sound pressure of the first acoustic sound and the sound pressure of the second acoustic sound, is adjusted to be equal to or greater than 0.5 times the sound pressure of the first acoustic sound in the crossover frequency range so as to improve the acoustic properties in the crossover frequency range.
