摘要： A multi-function coil for use in a magnetic pickup apparatus for transducing the mechanical motion of the stings of an instrument wound on a single coilform structured to separate the single continuous coil into first and second collinear segments in each of two winding spaces, each coil having a predetermined number of turns and being uniformly spaced one from the other, for substantially eliminating distortion and harsh sounding overtones by the reduction of the mutual inductance of the first and second segments of the single continuous coil.

摘要： An electromagnetic pickup for a stringed musical instrument incorporating a magnetic structure placed between two elongated collinear coils of opposing polarity. The magnetic structure includes a number of ferromagnetic polepieces that extend through the collinear coils and two ferromagnetic moderator bars adjacent to and on opposite sides of the polepieces (within the area between the two coils) that are charged with one polarity by high coercive permanent magnets attached to the outer surface of the moderator bars.

摘要： A pickup apparatus for a stringed musical instrument includes an electromagnetic string vibration sensor, preferably including at least one winding, and a feature associated therewith, preferably a conductive closed circuit around the winding, to suppress resonant peaks and thereby equalize the harmonic reproduction. The apparatus preferably includes two such windings and circuits connected in a hum-canceling manner. A second hum-canceling pair of windings having a lower inductance to reproduce clean highs without phase cancellation can be added along with a resistive-capacitive network so that the combination can reproduce a wide variety of different sounds, all at a consistent high output level.

摘要： A sound pickup for a stringed musical instrument has a hollow open-topped housing with a base plate matingly fitting in the housing; the housing is formed of ABS plastic coated with copper nickel-chrome layers. The base plate is formed of ABS with its outer surface being nickel plated; two parallel slots in the base plate frictionally receive lower edges of parallel elongated coil core blades. An elongated magnet is positioned between the core blades and first and second coil assemblies including elongated slotted plastic bobbins are fitted over the core blades to overlie the magnet with lugs on the bobbins facing opposite ends of the magnet to hold it in position. A cable is connected to the coil members and extended outwardly through the housing with the base plate, coil and blade assembly being positioned in the housing and filled with potting material so that the upper ends of the bobbins and blade members extend outwardly above the housing with the remaining components being held by the potting material upon solidification and additional retention being provided by screw members extending through the bottom of the housing into the base plate.
