Variable resonant bifilar single coil magnetic pickup
View Patent ↗A bifilar pickup for an electrical stringed musical instrument is provided. The bifilar pickup comprises a single coil wherein the coil is formed with two closely spaced but electrically isolated parallel wound wires. A guitar in combination with the bifilar pickup is additionally provided.
1. A pickup for a stringed electrical musical instrument comprising:
a permanent magnet; and
a single coil form associated with the magnet, wherein the single coil form is wound with at least two wires, further wherein the at least two wires are wound in a parallel manner with coaxial turns, and yet further wherein the at least two wires are electrically isolated from each other.
2. The pickup of claim 1 wherein one of the wires has a first end connected with an output and a second end connected with a ground.
3. The pickup of claim 1 wherein at least one of the wires forms a closed circuit.
4. The pickup of claim 3 wherein the closed circuit further comprises a resistor.
5. The pickup of claim 1 further comprising at least one pole piece associated with the magnet, wherein the single coil form is placed around the at least one pole piece.
6. The pickup of claim 5 , further comprising a bobbin, wherein the bobbin is placed around the at least one pole piece, further wherein the single coil form is wound around the bobbin.
7. The pickup of claim 6 wherein the bobbin is a generally rectangular shape.
8. The pickup of claim 1 wherein the permanent magnet is an Alnico magnet.
9. The pickup of claim 1 wherein the permanent magnet is a ceramic magnet.
10. The pickup of claim 1 wherein the at least two wires are wound about 5000 times.
11. The pickup of claim 1 wherein the at least two wires are insulated copper AWC 42.
12. A stringed electrical musical instrument comprising:
a guitar; and
a pickup mounted on the guitar, wherein the pickup comprises a permanent magnet;
and a single coil form associated with the magnet, wherein the single coil form is simultaneously wound with at least two wires, further wherein the at least two wires are wound in a parallel manner with coaxial turns, and yet further wherein the at least two wires are electrically isolated from each other.
13. The stringed electrical musical instrument of claim 12 wherein one of the wires has a first end connected with an output and a second end connected with a ground.
14. The stringed electrical musical instrument of claim 12 wherein at least one of the wires forms a closed circuit.
15. The stringed electrical musical instrument of claim 14 wherein the closed circuit further comprises a resistor.
16. The stringed electrical musical instrument of claim 13 further comprising at least one pole piece associated with the magnet, wherein the single coil form is placed around the at least one pole piece.
17. The stringed electrical musical instrument of claim 16 , further comprising a bobbin, wherein the bobbin is placed around the at least one pole piece, further wherein the single coil form is wound around the bobbin.
18. The stringed electrical musical instrument of claim 17 wherein the bobbin is a generally rectangular shape.
19. The stringed electrical musical instrument of claim 13 wherein the permanent magnet is an Alnico magnet.
20. A stringed electrical musical instrument comprising:
a guitar; and
a pickup mounted on the guitar, wherein the pickup comprises a permanent magnet, wherein the permanent magnet is an Alnico magnet;
a coil associated with the magnet, wherein the coil is simultaneously wound with at least two wires, further wherein the at least two wires are wound in a parallel manner with coaxial turns, and yet further wherein the at least two wires are electrically isolated from each other, wherein one of the wires has a first end connected with an output and a second end connected with a ground, further wherein at least one of the wires forms a closed circuit, yet further wherein the closed circuit further comprises a resistor;
at least one pole piece associated with the magnet, wherein the coil is placed around the at least one pole piece; and
a bobbin, wherein the bobbin is placed around the at least one pole piece, further wherein the coil is wound around the bobbin, wherein the bobbin is a generally rectangular shape.
