Abstract: The problem of providing an electroacoustic converter for wide-band loudspeakers or magnetless electrodynamic headphones for generating sound, in particular for application in the homogeneous and/or nonhomogeneous magnetic field of a magnetic resonance tomograph, an electroacoustic converter avoiding the drawbacks of the prior art, is essentially resolved in that the electroacoustic converter for generating sound comprises an elastically suspended oscillating body, whereby the oscillating body consists of a non-elastic or low-elastic, non-magnetic or only weakly magnetic material and is flatly and in a fixed manner connected with conductor paths, on which a Lorentz force is acting as the driving force when current is flowing. The Lorentz force is supplied by the magnetic field of the magnetic resonance tomograph.
