Abstract: An electromechanical transducer of the invention comprises a structural unit, an armature, and the first and second elastic units. The structural unit includes magnets, a yoke and a coil. The armature includes an inner portion disposed to pass through inside the structural unit and two outer portions protruding from the inner portion in a first direction, and the armature constitutes a magnetic circuit with the structural unit via two regions through which components of the magnetic flux flow in reverse directions in the inner region. The elastic units give restoring forces to the outer portions in response to displacement of the armature due to magnetic forces of the magnetic circuit. In the armature, a cross-sectional area at a predetermined position between the two regions is smaller than that at the two regions, and magnetic flux flowing in the first direction within a range of displacement of the armature.
