Abstract
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 metallic non-magnetized pole pieces are arranged in the second coil. Oppositely directed U-shaped shields each having a web and outwardly directed opposed flanges are arranged back to back and receive the coils to shield the coils from each other both magnetically and inductively.
Claims18
A transducer having a first coil, a second coil arranged with its axis coincident with the axis of the first coil and in use spaced below the first coil, a metallic shield made of magnetically permeable material arranged between the coils, the shield having one or more outwardly directed walls with the wall or walls of the shield extending over sides of the coils, at least one permanent magnet pole piece associated with the first coil and at least one metallic magnetically permeable pole piece associated with the second coil, whereby the coils are inductively and magnetically decoupled from one another by the shield.
