To prevent attenuation of vibrations with a thin type by exercising ingenuity in the shape of an exciting coil and the arrangement and configuration of a magnetism generating body.

The electromagnetic acoustic transducer is provided with a thin sounding plate (1) disposed within the magnetic field of a magnetism generating body and supported at its outer peripheral part by a portion of a housing (H) and the exciting coil (2) formed of printed wiring at this sounding plate and is provided with the magnetism generating body (4) disposed to face the sounding plate across a gap and a planar elastic body (6) placed on the magnetism generating body across a weight (4a). The outer peripheral part of the planar elastic body is supported at a base (3) which is a portion of the housing, by which the planar elastic body is supported overhead in the air to move vertically.
