TRANSDUCER FOR A STRINGED MUSICAL INSTRUMENT

摘要

A transducer for a stringed instrument comprises a first uppermost coil and a second lowermost coil with the axes of the coils coincident. Permanent magnet pole pieces are arranged in the first coil and either permanent magnet or metallic non-magnetised pole pieces are arranged in the second coil. Oppositely directed U-shaped shields each having a web and outwardly directed opposed walls are arranged back to back and receive the coils to shield the coils from each other both magnetically and inductively.
