description A speaker includes: a pair of front-side and back-side vibration portions each having a dielectric layer having insulating properties and made of an elastomer or resin, a front-side electrode layer placed on a front side of the dielectric layer and having conductive properties, and a back-side electrode layer placed on a back side of the dielectric layer and having conductive properties; an interposed member placed between the pair of vibration portions so that the front-side vibration portion protrudes toward a front side and the back-side vibration portion protrudes toward a back side; and a circuit section that transmits signal waves based on sound to be reproduced to the pair of vibration portions so that the signal waves transmitted to the pair of vibration portions have opposite phases to each other, and drives the pair of vibration portions.
