An electroacoustic transducer comprises a terminal (1-1'), a voice coil (2) coupled to the terminal, and a diaphragm (4). The transducer further comprises an element (other than the voice coil) made of a superconducting material which cooperates with the voice coil (2) to provide electromechanical conversion of an electric signal appearing at the terminal (1-1') into vibrations of the diaphragm, or vice versa.
