Claims
- 1. A pick-up assembly for a stringed musical instrument having a plurality of moveable strings comprising:
- a case including means for forming a longitudinal channel;
- at least one first magnet disposed in said longitudinal channel along an interior side of said channel forming means;
- at least one coil means disposed in the interior of said longitudinal channel and having a vertical height less than a vertical height of the interior side of said channel forming means; and
- a plurality of second magnets disposed in the interior of said longitudinal channel and extending horizontally between an interior bottom of said channel forming means and said coil means such that an upper surface of said coil means is near an upper surface of the interior side of said channel forming means.
- 2. A pick-up assembly as set forth in claim 1 wherein said at least one first magnet is a generally planar permanent magnet strip.
- 3. A pick-up assembly as set forth in claim 2 wherein said permanent magnet strip extends longitudinally.
- 4. A pick-up assembly as set forth in claim 1 wherein said permanent magnet strip is rectangular in shape.
- 5. A pick-up assembly as set forth in claim 1 wherein said second magnets are planar permanent magnet strips.
- 6. A pick-up assembly as set forth in claim 2 wherein said permanent magnet strips extends longitudinally.
- 7. A pick-up assembly as set forth in claim 1 wherein said permanent magnet strips are rectangular in shape.
- 8. A pick-up assembly as set forth in claim 1 wherein said second magnets are stacked upon each other.
- 9. A pick-up assembly as set forth in claim 1 wherein said second magnets are adhered to each other.
- 10. A pick-up assembly as set forth in claim 1 wherein said first and second magnets have a first common magnetic polarity impressed on said case and a second common polarity facing toward the interior of said longitudinal channel.
- 11. A pick-up assembly as set forth in claim 1 wherein said case extends longitudinally and has a U-shape.
- 12. A pick-up assembly as set forth in claim 1 wherein said case has a planar base wall and a pair of planar side walls parallel to each other and perpendicular to said base wall to form said longitudinal channel.
- 13. A pick-up assembly as set forth in claim 1 wherein said case is made of a ferromagnetic material.
- 14. A pick-up assembly as set forth in claim 1 wherein said coil means comprises at least one core piece having a coil wrapped around said at least one core piece.
- 15. A pick-up assembly as set forth in claim 1 wherein said coil means comprises a plurality of core pieces extending longitudinally and a coil wrapped around said core pieces.
- 16. A pick-up assembly as set forth in claim 1 wherein said channel forming means comprises a base wall and a pair of side walls forming a U-shape.
- 17. A pick-up assembly for a stringed musical instrument having a plurality of moveable strings comprising:
- a case having a longitudinal channel;
- at least one first magnet disposed in said longitudinal channel along an interior side of said case;
- at least one coil disposed in the interior of said longitudinal channel and having a vertical height less than a vertical height of the interior side of said case; and
- a plurality of second magnets disposed in the interior of said longitudinal channel and stacked horizontally between an interior bottom of said case and said coil such that an upper surface of said coil is near an upper surface of the interior side of said case.
- 18. A pick-up assembly as set forth in claim 1 wherein said second magnets are planar permanent magnet strips that extend longitudinally.
- 19. A pick-up assembly as set forth in claim 1 wherein said coil comprises at least one longitudinally extending core piece having conductive wire wrapped around said at least one core piece.
- 20. A pick-up assembly for a stringed musical instrument having a plurality of moveable strings comprising:
- a base wall and a pair of side walls forming a U-shape and a longitudinal channel;
- at least one first permanent magnet strip disposed in said longitudinal channel along each of said side walls;
- a coil having plurality of core pieces extending longitudinally and conductive wire wrapped around said core pieces and disposed in the interior of said channel; and
- a plurality of second permanent magnet strips disposed in the interior of said longitudinal channel and stacked horizontally upon each other and disposed between said base wall and said coil such that an upper surface of said coil is near an upper surface of said side walls.
