Abstract
An electrodynamic transducer has a diaphragm substantially having two parts with different profiles, namely an acoustically active central part and an annular part laterally adjoining the central part and serving for the resilient suspension of the diaphragm in its entirety. A narrow coil seat for a wire coil of the transducer is located between the central part and the annular part. For the purpose of developing a compact yet electrodynamically sensitive acoustic transducer, the annular part is not arranged radially outside the central part of the diaphragm, but is shifted inward according to the invention. The curved annular part is thus accommodated under the axial curvature of the central part. The annular part can therefore have the annular width required for an ideal resilient suspension without negatively affecting the outer dimensions of the transducer.
