An electromechanical transducer of the invention comprises a structural unit, an armature (22) , and first and second elastic members (23, 24). The structural unit includes at least one pair of magnets (14, 17), a yoke (11, 12) conducting a magnetic flux generated by the magnets, and a coil (13) supplied with an electric signal. The armature (22) has an inner portion (22a) disposed to pass through an internal space of the structural unit and first and second outer portions (22b, 22c) protruding on both sides from the inner portions, and the armature constitutes a magnetic circuit with the structural unit via two regions through which components of the magnetic flux flow in directions opposite to each other in the inner portion. The first and second elastic members (23, 24) connect between the first and second outer portions of the armature and the structural unit, respectively. |
