Abstract

Coils for receiving or transmitting electromagnetic signals comprising a plurality of concurrently wound and fully or partially interpenetrating windings for which the resonance frequency can be varied over a broad range. The presently described embodiments provide for electromagnetic pickups for stringed musical instruments; however, it is appreciated that other embodiments providing for a wide variety of devices comprising pickup coil sensors are apparent. It is also apparent that a wide variety of devices are possible in which coils with concurrently wound and interpenetrating windings will serve as transmitting coils.

Claims

1. A pickup coil sensor comprising:

a plurality of windings comprising partially and secondary windings wound concurrently to form a region of partially interpenetrating windings; and

the region of the partially interpenetrating windings beginning in the midst of the primary windings.

2. A sensor as in claim 1 wherein the primary and secondary windings are of the same gauge.

3. A sensor as in claim 1 wherein the primary and secondary windings are of different gauges.

4. A sensor as in claim 1, wherein the individual windings of the primary and secondary windings have a different number of turns.

5. A sensor as in claim 1 wherein the region of the partially interpenetrating windings terminates at one end of the plurality of the windings.

6. A sensor as in claim 1 wherein the region of the partially interpenetrating windings terminates in the midst of the primary windings.

7. A sensor as in claim 1 wherein the region of the partially interpenetrating windings terminates in the midst of the secondary windings.

8. A pickup coil sensor comprising:

a core;

a primary winding at least partially surrounding the core;

a secondary winding at least partially surrounding the core; and

a region comprising the primary and secondary windings being at least partially interpenetrating, at least one of a beginning and an ending of the region being in the midst of one of the primary and secondary windings.

9. The sensor of claim 8 wherein the region begins at the start of the primary and secondary windings.

10. The sensor of claim 8 wherein the region begins in the midst of the primary winding.

11. The sensor of claim 8 wherein the region ends in the midst of the secondary winding.

12. The sensor of claim 8 wherein the region ends in the midst of the primary winding.

13. The sensor of claim 8 wherein the region begins and ends in the midst of the primary winding.

14. The sensor of claim 8 wherein the region begins at the start of the primary and secondary windings and ends in the midst of the primary winding.

15. The sensor of claim 8 wherein the region begins in the midst of the primary winding and ends at the end of the primary and secondary windings.

16. The sensor of claim 8 wherein the region begins in the midst of the primary winding and ends in the midst of the secondary winding.

17. A method for adjusting the frequency response characteristics of a pickup coil sensor, the method comprising:

providing a pickup coil sensor comprising primary and second windings that establish a region of at least partially interpenetrating;

adjusting the frequency response characteristics of the pickup coil sensor by performing at least one of the following;

altering the number of turns in each of the primary and secondary windings;

altering the degree of interpenetration in the region; and

altering the position where the region of the interpenetration occurs in the pickup coil sensor.

18. The method of claim 17 wherein the adjusting comprises altering the degree of interpenetration in the region.

19. The method of claim 17 wherein the adjusting comprises altering the position where the region of the interpenetration occurs in the pickup coil sensor.
