Abstract: An electroacoustic transducer includes an electromechanical transducer and a casing. The electromechanical transducer transduces an electric signal into mechanical vibration. The housing can be attached to a cavum conchae without blocking an external auditory canal, in which the electromechanical transducer is housed, and vibrates due to the mechanical vibration caused by the electromechanical transducer to generate sound. The housing includes an inner housing portion located on the external auditory canal side and an outer housing portion located on an external environment side when the housing is attached to the cavum conchae. The housing has an ellipsoidal shape or an oval shape.

Abstract: An electromechanical transducer includes: a structural portion configured such that two pairs of magnets magnetized in opposite directions, a yoke configured to guide magnetic fluxes from the magnets, and a coil configured to receive a supplied electric signal are located integrally; an armature having an inner portion penetrating an internal space of the structural portion and outer portions protruding from the inner portion toward both sides in a first direction, forming, together with the structural portion, a magnetic circuit through regions of the inner portion facing the two pairs of magnets, and configured to displace in a second direction perpendicular to the first direction by magnetic force of the magnetic circuit; and a pair of elastic members each located on both sides of the armature in the second direction, and configured to provide, to the armature, restoring force according to relative displacement of the armature corresponding to the structural portion.

Abstract: An electromechanical transducer of the invention comprises a structural unit, an armature, and first and second elastic members. The structural unit includes at least one pair of magnets, a yoke conducting a magnetic flux generated by the magnets, and a coil supplied with an electric signal. The armature has an inner portion disposed to pass through an internal space of the structural unit and first and second outer portions protruding on both sides 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 directions opposite to each other in the inner portion. The first and second elastic members connect between the first and second outer portions of the armature and the structural unit, respectively.
