Abstract
This electromechanical transducer includes a pair of magnets, a pair of yokes that each comprise a plurality of yoke components superposed over each other in a flat-plate-form region and that guide magnetic fluxes generated by the magnets, a hollow-core coil to which an electric signal is supplied, an armature passed through a space inside a structural section formed by integrally arranging the magnets and the coil on the inner sides of the pair of yokes, and a pair of elastic members that each engage the structural section and the armature.
