PROBLEM TO BE SOLVED: To make a volume and a signal output so as not to be reduced in a pickup and to make the vibration of a stringe so as not to be reduced by allowing at least either the first electromagnetic transducer of a high-pitched tone range side or the second electromagnetic transducer of a low-pitched tone range side to perform an electromagnetic transducing till the neighborhood of the central line and eliminating a vacant area. SOLUTION: In the first electromagnetic transducer 1 of an electromagnetic transducer 41, a coil 3 is wound around a pole piece magnet 5 and in the second electromagnetic transducer of it, a coil 4 is wound around a pole piece magnet 6. At least one of the pole piece magnets 5, 6 is inclined in the range from 5 degrees to 60 degrees with respect to the traversing direction of a string. The pole piece magnets 5, 6 are arranged so as to be in contact or overlapped with respect to a central line 30 at the vicinity of the central line 30. Thus, even when the stringe is moved to the vicinity of the central line 30, the pole piece magnets 5, 6 and the coils 3, 4 exist and an electromagnetic conversion efficiency is maintained and the reduction of the volume is not large in the pickup and the vibration of the string is not largely reduced in the driver. |
