    摘要： An electromechanical transducer of the invention comprises a structural unit, an armature, and two elastic units. The structural unit includes magnets, a yoke and a coil. The armature has an inner portion disposed to pass through inside the structural unit and two outer portions protruding from the inner portion, 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. Each of the elastic units includes a pair of elastic members symmetrically arranged via the armature in a direction of the displacement. Each of the elastic members has one end engaging one of the outer portions and another end engaging one of the elastic member attaching portions.

    摘要： 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.
