Electroacoustic transducer comprising a superconducting element

The electroacoustic transducer comprises a terminal (1-1 min ), a voice coil (2) coupled to the terminal, and a diaphragm (4). The transducer further comprises an element (not being the voice coil) made of a superconducting material, which element cooperates with the voice coil (2) to provide electr...

More Information
Summary:The electroacoustic transducer comprises a terminal (1-1 min ), a voice coil (2) coupled to the terminal, and a diaphragm (4). The transducer further comprises an element (not being the voice coil) made of a superconducting material, which element cooperates with the voice coil (2) to provide electromechanical conversion of the electric signal appearing on the terminal (1-1 min ) into vibrations of the diaphragm (4), or vice versa.
