Abstract

A humbucking pickup for a musical instrument has a bobbin assembly with first and second bobbins. The musical instrument can be an electric guitar. A first coil is wound around the first bobbin, and a second coil is wound around the second bobbin. A permanent magnet or a plurality of permanent magnets extend through the first coil and second coil of the bobbin assembly. A housing is disposed over the bobbin assembly. Blades are disposed over side surfaces of the housing to redirect the magnetic flux toward the strings. A plurality of strings of the musical instrument is routed over a top surface of the housing parallel to opposing poles of the permanent magnet. Movement of the strings of the musical instrument disturbs a magnetic flux of the permanent magnet proximate to a first pole of the permanent magnet and a second pole of the permanent magnet.

Claims

1. A humbucking pickup for a musical instrument, comprising:

a bobbin assembly including a first bobbin and a second bobbin;

a first coil wound around the first bobbin;

a second coil wound around the second bobbin;

a permanent magnet extending through an opening in the first bobbin and second bobbin with the first coil and second coil disposed around the permanent magnet; and

a housing disposed over the bobbin assembly, wherein the permanent magnet is oriented in parallel to a top surface of the housing.

2. The humbucking pickup of claim 1, wherein a plurality of strings of the musical instrument is routed over the top surface of the housing in parallel to opposing poles of the permanent magnet.

3. The humbucking pickup of claim 1, further including:

a first blade disposed along a first side surface of the housing over a first pole of the permanent magnet; and

a second blade disposed along a second side surface of the housing opposite the first side surface over a second pole of the permanent magnet.

4. The humbucking pickup of claim 1, further including:

a first pole shoe disposed over a first pole of the permanent magnet;

a first pole screw inserted into the first pole shoe;

a second pole shoe disposed over a second pole of the permanent magnet; and

a second pole screw inserted into the second pole shoe.

5. The humbucking pickup of claim 1, further including a plurality of permanent magnets extending through the first coil and second coil of the bobbin assembly.

6. The humbucking pickup of claim 1, wherein the musical instrument includes an electric guitar, electric bass guitar, or string musical instrument incorporating the humbucking pickup.

7. A musical instrument including a humbucking pickup, the humbucking pickup comprising:

a bobbin assembly including a first coil wound around a first bobbin and a second coil wound around a second bobbin; and

a permanent magnet extending through an opening in the first bobbin and second bobbin with the first coil and second coil disposed around the permanent magnet, wherein the permanent magnet is oriented in parallel to a surface of the musical instrument.

8. The musical instrument of claim 7, further including a housing disposed over the bobbin assembly.

9. The musical instrument of claim 8, further including:

a first blade disposed along a first side surface of the housing over a first pole of the permanent magnet; and

a second blade disposed along a second side surface of the housing opposite the first side surface over a second pole of the permanent magnet.

10. The musical instrument of claim 8, wherein a plurality of strings of the musical instrument is routed over a top surface of the housing parallel to opposing poles of the permanent magnet.

11. The musical instrument of claim 7, further including:

a first pole shoe disposed over a first pole of the permanent magnet;

a first pole screw inserted into the first pole shoe;

a second pole shoe disposed over a second pole of the permanent magnet; and

a second pole screw inserted into the second pole shoe.

12. The musical instrument of claim 7, further including a plurality of permanent magnets extending through the first coil and second coil of the bobbin assembly.

13. The musical instrument of claim 7, wherein the musical instrument includes an electric guitar, electric bass guitar, or string musical instrument incorporating the humbucking pickup.

14. A method of making a humbucking pickup, comprising:

providing a bobbin assembly including a first bobbin and a second bobbin;

winding a first coil around the first bobbin;

winding a second coil around the second bobbin;

disposing a permanent magnet through an opening in the first bobbin and second bobbin with the first coil and second coil disposed around the permanent magnet; and

disposing a housing over the bobbin assembly, wherein the permanent magnet is oriented in parallel to a top surface of the housing.

15. The method of claim 14, further including routing a plurality of strings of the musical instrument over the top surface of the housing in parallel to opposing poles of the permanent magnet.

16. The method of claim 14, further including:

disposing a first blade along a first side surface of the housing over a first pole of the permanent magnet; and

disposing a second blade along a second side surface of the housing opposite the first side surface over a second pole of the permanent magnet.

17. The method of claim 14, further including:

disposing a first pole shoe over a first pole of the permanent magnet;

inserting a first pole screw into the first pole shoe;

disposing a second pole shoe over a second pole of the permanent magnet; and

inserting a second pole screw into the second pole shoe.

18. The method of claim 14, further including disposing a plurality of permanent magnets through the first coil and second coil of the bobbin assembly.

19. The method of claim 14, wherein the musical instrument includes an electric guitar, electric bass guitar, or string musical instrument incorporating the humbucking pickup.

20. A method of making a humbucking pickup for a musical instrument, comprising:

providing a bobbin assembly including a first coil wound around a first bobbin and a second coil wound around a second bobbin; and

disposing a permanent magnet through the first coil and second coil of the bobbin assembly, wherein the permanent magnet is oriented in parallel to a surface of the musical instrument.

21. The method of claim 20, further including disposing a housing over the bobbin assembly.

22. The method of claim 21, further including:

disposing a first blade along a first side surface of the housing over a first pole of the permanent magnet; and

disposing a second blade along a second side surface of the housing opposite the first side surface over a second pole of the permanent magnet.

23. The method of claim 21, further including routing a plurality of strings of the musical instrument over a top surface of the housing parallel to opposing poles of the permanent magnet.

24. The method of claim 20, further including:

disposing a first pole shoe over a first pole of the permanent magnet;

inserting a first pole screw into the first pole shoe;

disposing a second pole shoe over a second pole of the permanent magnet; and

inserting a second pole screw into the second pole shoe.

25. The method of claim 20, further including disposing a plurality of permanent magnets through the first coil and second coil of the bobbin assembly.
