Definitions
- An electrical pickup for a stringed musical instrument such as a guitar, comprises a pair of axially spaced coils, a ferromagnetic pole piece spanning the space etween the coils and extending into each coil and having a portion between the coils which extends mm.
- d m who w mmm. .m d t d 0 6 b mfim m ELECTRICAL PICKUP FOR A STRINGED 3,711,619
- magnet means having a pole face die pole piece and directing a magnetic 1e piece of a single magnetic polarity
- ans preferably comprising two pennanent magnets disposed at opposite sides of the coils directing magnetic fields into the pole piece from opposite sides thereof of the same magnetic polarity.
- FIG. 1 is a cross-sectional view of a pickup constructed in accordance with the present invention
- FIG. 1A is a partial cross-sectional view of the pickup of FIG. 1, illustrating a preferred mounting means for the pickup;
- FIG. 2 is a partially cut away top view of the pickup shown in FIG. 1;
- FIG. 3 is a diagram showing connection of the coils; and 7 FIG. 4 illustrates alternate mounting means.
- the principles of the present invention are particularly useful when embodied in an electric pickup for a stringed musical instrument, such as a guitar.
- the pickup as shown in FIG. 1, is generally indicated by the numeral 10.
- the pickup 10 includes a pair of axially spaced coils 11, 12 each comprising a bobbin 13 with an appropriate number of turns of wire of a proper size discussed below.
- the coils ll, 12 have axes which are concentric with each other and thus extend along the length of one of the instrument strings 14 of which there may be several as shown.
- a pole piece 15 formed of ferromagnetic material extends from the left edge of the coil 11 to the right edge of the coil 12, thus spanning the space between the coils 11, 12 and being disposed therein.
- the pole piece 15 has a portion 16 between the coils ll, 12 which extends toward the string 14.
- the portion 16 comprises an adjustable screw of a ferromagnetic material disposed
- two coils are employed to eliminate hum but they are so arranged and disposed so that they are both active,preventing loss of signalfrom use of the second coil.
- the boost and cancellation problems resulting from spaced coils are eliminated by sensing string vibration at a rather narrow spot on'the string.
- a pair of coils are arranged to have their axes extend'in the "samedirection 'as the string, a ferromagnetic pole piece is disposed in the coils and spans the space between them, it having a portion between the- 'coils prbjecting toward each string, and permanent magnet means are disposed at opposite sides of the coils and direct a magnetic field of a single magnetic polarity into the pole piece from opposite sides thereof.
- Another object of the present invention is to provide a pickup construction which will eliminate hum, but which will not sacrifice signal level in doing so.
- Another object of the present invention is to provide a pickup construction for a stringed musical instrument which has a substantially uniform response over the full frequency range of the instrument.
- the pickup 10 further includes permaneht magnet means, here comprising two permanent magnets 17, 18 disposed at opposite sides of the coils l 1-, 12 and directing their magnetic fields into the pole piece 15 from opposite sides thereof. As shown, only one magnetic polarity, shown here by way of examplev as North, is directed to the pole piece 15. Each magnet pole having North polarity is directed away from each magnet pole having South polarity, and such direction or facing is along the length of the string 14.
- the invention is operative andcan be used with a single string, it preferably is so constructed that the coils 11, 12, the magnets 17, 18, and the pole piece 15 are elongated in a direction transverse to the length of the string 14 so as to be responsive to a plurality of such parallel strings.
- Magnets 17 and 18 should be of sufficient length and be positioned so as to provide a substantially uniform magnetic field of a single magnetic polarity through said pole piece.
- the magnetic pole piece has four shoulders 19 against which the bobbins 13 of the coil assemblies 11, 12 abut. After the coils ll, 12 have been placed on the pole piece 15, whenn the magnets l7, 18 are placed there against, they act so strongly on the pole piece as to actually trap and hold the components in assembled relationship. However, tape may be added if desired, particularly to assure that the components will stay together until they are encased.
- FIGS. 1 and 1A One type of encasement is shown in FIGS. 1 and 1A which includes a flanged base 20 which supports the pole piece by means of screws 21 and spacers 22 (see FIG. 1A).
- a cover 23 is secured to the base and is suitably apertured as at 24 to provide access to the adjustable magnetic screws 16.
- an extruded plastic base 25 shown in FIG. 4 may be utilized, the same being partially hollow to receive nestingly the structure otherwise shown in FIG. 1.
- Use of an extrusion to provide a partially hollow mounting base yields an external configuration of uniform cross section to which the cover 23 may be attached.
- the coils 11, 12 are identical and the left end of each coil in FIG. 3 denotes the starting end of the winding, whereby, as shown, they are connected in out-of-phase relationship with each other.
- One coil is as active as the other in connection with the induction of signals and yet they sense at a single point for each string (the end of the corresponding screw 16) because of the construction of the pickup in its entirety.
- I have used 4,250 turns of No. 42 wire per coil. This produces an impedance which is suitable for most present day typical guitar amplifiers. If a greater or lesser impedance is desired, the number of turns is respectively increased or reduced correspondingly.
- a pickup 10 constructed as shown and described senses the vibration of a string only at the pole piece portion 16 and thus produces a sound response which is substantially uniform over the full frequency range of the instrument.
- the bottom side representing the lower end of the screw 16 can also sense inphase, but is not utilized in the present installation illustrated.
- each magnet 17, 18 is oriented so that a side between the poles, which is neutral, rather than a pole, faces toward the string, and therefore there is no sensing by such magnets at these neutral areas.
- the pickup truly picks up only at a single point for each string.
- An electrical pickup for a stringed musical instrument comprising:
- permanent magnet means having a pole face directed toward said pole piece, and directing a magnetic field into said pole piece of a single magnetic polarity.
- said permanent magnet means comprises two permanent magnets disposed at opposite sides of said coils and directing magnetic fields into said pole piece from opposite sides thereof of the same magnetic polarity.
- a pickup according to claim 1 in which said coils are connected in series in out-of-phase relation to each other.
- a pickup according to claim 1 in which said coils, said magnets, and said pole piece are elongated in a direction transverse to string length so as to be responsive to a plurality of parallel strings.
- a pickup according to claim 1 in which said pole piece has oppositely facing shoulders engaging said coils and thus defining the axial spacing therebetween.
- a pickup according to claim 1 in which said portion extending toward the string comprises an adjustable screw disposed to be accessible for adjustment when assembled on the instrument.
- a pickup according to claim 5 which includes a partially hollow mounting base receiving said coils, said magnets and said pole piece, said base'having an external configuration of uniform cross section and a cover closing said base.
- An electrical pickup for a stringed musical instrument comprising:
- a a pair of axially spaced coils arranged to have their axes extend along the length of an instrument string; said coils being connected in series out of phase relation with each other;
- c. means for providing a magnetic field of a single magnetic polarity which is substantially uniform through said pole piece.
