Description

POLY-COIL MATRIX

FIELD OF THE INVENTION

The present invention relates to electronic mechanisms. In particular, the present 'invention relates to pickups having a plurality of coils.

BACKGROUND OF THE INVENTION

There has long existed the need for an apparatus and system whereby a user can widen or lengthen a pick at will without replacing the entire pickup. This imperative coincides with an added desire to limit the size of pickup due to the confined space available in pickups. This is true in the world of music instruments, stringed musical instruments, speakers and sound systems. This has proven to be especially relevant to those in the field of music and/or sound who requiring a high degree of versatility and clarity of sounds.

The traditional means of producing a pickup, has proven to have a number of significant drawbacks. The more prevalent of these drawbacks include the above-mentioned widen or lengthen a pick at will without replacing the entire pickup.

Many "pickup" inventions and methods now exist to ensure that users can choose between rather a "long" pickup or a "wide" pickup. By way of example only, in the realm of "electric guitars", the most notable styles are those of Gibson™ and Fender™. The present invention introduces a new apparatus and system for achieving a high degree of versatility and sound enhancement.

Thus, such inventions as those described above generally suffer from at least one of several disadvantages, including, amongst others, the lack of an ability to choose modification of pickup style from "wide" to "long" or from "long" to "wide". Therefore, the need exists to create a system whereby the foregoing disadvantages are adequately remedied to provide a modifiable alternative.

DETAILED DESCRIPTION OF THE INVENTION

Figure 1 shows a plan view of a stringed instrument 10. By way of example only, a solid body electric guitar 12 is shown. Electric guitar 12, which is illustrative of a typical solid-body electric guitar, comprises a headstock 14, a neck 16, and a body 18. Upon reading the teachings of this specification, those of ordinary skill in the art will now understand that, under appropriate circumstances, considering such issues as trends in musician preferences, etc., other stringed instruments, such as, for example, a hollow body electric guitar, a semi-hollow body electric guitar, an electric guitar with more than six strings, e.g., a seven-string electric guitar, a twelve-string electric guitar, etc., an electric guitar with less than six strings, a electric double-neck guitar, a carved-top electric guitar, an arch-top electric guitar, an acoustic-electric guitar, an electric mandolin, an electric violin, an electric banjo, an electric stringed instrument with more than six strings, an electric stringed instrument with less than six strings, etc., may suffice.

Guitar 12 comprises strings 20 which typically comprise steel. Guitar 12, shown in Figure 1 , is commonly referred to as a six-string guitar. Strings 20 of guitar 12 are under tension from headstock 14 to a position on body 18, namely, a bridge 22, as shown. A six-string guitar, comprises six strings ranging in diameter to produce different tones. Each string of strings 20 is tuned to a particular guitarist-desired pitch. Optionally, "one piece" guitars with 16 integrally formed with body 18 are also known. Optionally, body 18 of guitar 12 comprises at least one electric component 24 for readily assisting in converting mechanical vibration of strings 20 into electrical signals.

Those electrical signals are typically subsequently amplified and sounded through a loud speaker. A guitarist "frets" (i.e., changes the effective string length by pushing the string against the neck) strings 20 and vibrates strings 20 with either the fingers of the guitarist or with a plectrum, also referred to as a "flatpick" or "pick", to perform music with guitar 12. Optionally, the guitarist may choose to use other devices to vibrate strings 20, such as a bow, an electric bow, a hammer (in a piano) and the like.

Electronic components 24 of guitar 12 comprise "pickups" 26, as shown. Pickups are magnetic transducers that induce a current in a wound coil wire positioned adjacent to a magnet. Guitar 12, as shown in Figure 1, comprises two single coil pickups 26.

By way of example only. Guitar 12 shown in Figure 1 also includes a "humbucker" pickup 27 including at least two coils.

The term "Humbucker" as used herein, shall include but will not be limited to: a conventional humbucker (or Humbucking pickup) a Humbucker for readily canceling out the interference (they "buck the hum") induced by alternating current, which is normally experienced with single coil pickups, an electric guitar pickup, first patented by Seth Lover and the Gibson company, using at least two coils, wherein at least one coil generates a string signal, a Humbucker having a high output since both coils are in series and the magnetic circuit is low loss, a humbucker inducing a slight magnetic field around the strings, which in turn induces an electrical current on the coils as the strings vibrate, a humbucker with at least two coils having opposite magnetic polarity, opposite windings and are connected in series or in parallel which causes noise and interference to be significantly reduced via common-mode rejection. Namely, opposite windings brings about an opposite electrical polarity.

A typical guitar 12 comprises at least one pickup 26 and/or "humbucker" pickup 27. Electronic components 24 of guitar 12 are electrically connected to each of pickup 26 in such a way guitar players may select which pickup 26 or combination of pickups 26 will be used. The pickup 26 selection is performed to shape the tone of the guitarists sound and provides an expressive musical component. In operation, the mechanical vibration of strings 20, wherein such strings 20 typically comprising steel or metal, in magnetic-field communication with pickup 26 and/or "humbucker" pickup 27, induces a current in the wound coil wire by affecting the magnetic flux of the adjacent magnet. The induced current signal, when electrically connected to an amplifier, is subsequently amplified. The amplified electric signal may then be sounded through a loud speaker as the electrical signal is converted into a mechanical wave signal.

Figure 2 shows an exploded view illustrating the components of a preferred poly-coil pickup 26 according to a preferred embodiment of the present invention. Poly-coil pickup 26 preferably includes a bottom flatwork 30, a first coil assembly 32, a second coil assembly 33 at least one pole piece 34 (six are shown), and a top flatwork (not shown in figure 2).

Preferably, pole pieces 34 are Alnico V magnets. Preferably, pole pieces 34 are self- magnetized. Alternately, pole pieces 34 may be magnetically conductive slugs influenced by an auxiliary magnet.

Preferably, each individual coil-wire wrapping of a coil assembly is preferably oriented around pole pieces 34, as shown. Upon reading the teachings of this specification, those of ordinary skill in the art will now understand that, under appropriate circumstances, considering such issues as designer preference, tonal quality desired, intended use, etc., other coil wrapping/magnetic pole piece arrangements, such as, having a coil wrapping oriented around more than one magnetic pole piece, such as around two adjacent magnetic pole pieces, around three adjacent magnetic pole pieces, around six adjacent magnetic pole pieces, etc., may suffice.

Poly-coil matrix is preferably wired so as to be in electronic communication with the output jack of the musical instrument. Preferably, the individual coil assembly wire wrappings are wired in series. Upon reading the teachings of this specification, those of ordinary skill in the art will now understand that, under appropriate circumstances, considering such issues as user preference, intended use, desired tone, noise cancellation, etc., other wiring arrangements, such as wiring each coil wrapping in parallel, wiring groups of coil wrappings in series, wiring in parallel groups of coil wrapping wired in series with other groups of coil wrapping wired in series, etc., may suffice.

Preferably, the individual coil assembly wire wrappings are wired in series. Upon reading the teachings of this specification, those of ordinary skill in the art will now understand that, under appropriate circumstances, considering such issues as user preference, intended use, desired tone, noise cancellation, etc., other wiring arrangements, such as wiring each coil wrapping in parallel, wiring groups of coil wrappings in series, wiring in parallel groups of coil wrapping wired in series with other groups of coil wrapping wired in series, etc., may suffice.

Preferably, coil assemblies are configured with the same winding direction (or electron travel) and magnetic polarity.

Pickups do not sense the string at a single point source, but rather over an area due to the width of the magnetic field. This sensing area is called the "aperture" of the pickup and is about 0.75 inches wide on a thin single coil pickup and about 2 inches wide on a wider pickup such as the Gibson humbucker.

Optionally and as shown in figures 6A and 6B, a plurality of coils are shown in a first horizontal matrix of concentric coils (48, 50, 52, 54, 56, 58, 60, 62, 64), a second horizontal matrix of concentric coils (66, 68, 70, 72, 74, 78, 80) and a third horizontal matrix of concentric coils (82, 84, 86, 88, 90, 92).

It is envisaged that many alternate "bridging" and connection combinations and/or controlling the coil gain in the poly coil matrix are facilitated within the spirit and scope of the invention beyond the options depicted in Figures 6A and 6B thereby creating a wide range of coil length and/or width. Thus, the poly coil matrix can readily bring about depth, density, sound resolution and clarity transcending those known in the art. Upon reading the teachings of this specification, those of ordinary skill in the art will now understand that, under appropriate circumstances, considering such issues as musician preference, future developments in musical pickup design, intended use, etc., other compatible pickup geometries and dimensions, such as a "P90" style pickup, a "Stratocaster" pickup, a "telecaster" pickup, a "full-size" "humbucking" style pickup, a Nano-mag style pickup, etc., may suffice.

Figure 7 shows the effect of the pickup aperture on the response can be calculated by averaging the point response over the aperture length. The pickup sensitivity will be greater in the middle than at the ends and the calculation brought herein is according to the average of sensitivity.

The poly coil matrix can readily bring about depth, density, sound resolution and clarity transcending those known previously. Optionally and as shown in Figure 7, the multiband logarithmic increase/decrease (compressing and expanding) bring about an enhancement of the unique properties of the poly coil matrix according to the present invention.

The methodology of using the flowchart with the accompanying formulas can readily achieve ranges, which would be impossible with physical poly coil matrix systems.

Thus, changes in specific segments can readily be achieved. Thus, digital and/or analog manipulation of poly coil matrix systems can yield surprising and even newer results of combining multiple capabilities into a single "sound".

Attempts have been made to do so with the human voice to obtain a multiple octave voice.

In the movie "Farinelli" separate recordings of a single piece by a plurality of singers were digitally melded together to produce a sound exceeding in range of Carlo Maria Broschi's voice as a "castrato" at an unequalled quality ever heard before.

Analogously, using the flow chart and formulas herein, a "melded" sound with the best qualities of both "long" and "wide" pickups can be simulated.

Where:

W_Wj_dCpickup is the width of the wide pickup in inches.

Performing the integration: (— cos( ^■)+cos( )]

Given the classic geometric equality: cos (a + b) = cos (a) cos (b)— sin ( ) s {b)

Thus, according to Figure 8, a user create a sound selected from the group of sounds between the "wide" pickup line and the "long" pickup line by using the formulas listed herein. It is envisaged that a person skilled in the art will be readily able to extrapolate and interpolate these results according to the teachings of the present invention as brought herein.

As can be seen in Figure 9, the poly coil mechanism can be readily used with speaker systems. Thus, as opposed to the poly coil pickup systems, the poly coil speaker system as shown in figure 9 is geared towards producing a wide range of sound by readily controlling the overall "length" and "width" of the coils within the speaker system of the present invention.

As shown in figure 9, a cone 94 with a coil cover 96 are attached to, or integrally formed with, a suspension diaphragm 98 and cylinder 100. Similarly to speakers known in the art, a magnet assembly 102 and permanent magnet 1 10 are provided.

Preferably, cone 94 is accommodated by a frame 106 and a suspension rim 104. A signal current is used with a plurality of concentric coils 108.

By way of example only, a plurality of coils are shown in a first horizontal matrix of concentric coils (1 12, 1 14, 1 16, 1 18, 120, 122) a second horizontal matrix of concentric coils (124, 126, 128, 130, 132, 134) and a third horizontal matrix of concentric coils (136, 138, 140, 142, 144, 146).

Optionally, "stacking" to create a three dimensional matrix of coils can readily be achieved by stacking at least two layers selected from the group consisting of: a first horizontal matrix of concentric coils (1 12, 1 14, 1 16, 1 18, 120, 122), a second horizontal matrix of concentric coils (124, 126, 128, 130, 132, 134) and a third horizontal matrix of concentric coils (136, 138, 140, 142, 144, 146).

It is further envisaged that a selection can be made of a coil within first horizontal matrix of concentric coils (1 12, 1 14, 1 16, 1 18, 120, 122), second horizontal matrix of concentric coils (124, 126, 128, 130, 132, 134) and third horizontal matrix of concentric coils (136, 138, 140, 142, 144, 146) which can be configured with winding creating a tapering contact between the coils selected from the group consisting of: first horizontal matrix of concentric coils (112, 1 14, 1 16, 1 18, 120, 122), a second horizontal matrix of concentric coils (124, 126, 128, 130, 132, 134) and a third horizontal matrix of concentric coils (136, 138, 140, 142, 144, 146). Thus, such a selection can readily facilitated a "smoothness" when selecting a combination of coils.

It is envisaged that a third "bridging" control 150 is situated in a location selected from the group consisting of: within poly coil matrix, externally to poly coil matrix or in adjacency to poly coil matrix.

Analogously, it is envisaged to use the present invention as a Dynamic microphone.

Dynamic microphones work via electromagnetic induction. Commonly, Dynamic microphones are robust, relatively inexpensive and resistant to moisture as well as their potentially high gain before feedback makes them ideal for on-stage use. The use of a poly coil matrix dynamic microphone would further enhance sound pickup.

Moving-coil microphones use the same dynamic principle as in a loudspeaker of figure 9, only reversed. A plurality of displaceable induction coils, positioned in the magnetic field of a permanent magnet, are attached to the diaphragm. When sound enters through the windscreen of the poly coil dynamic microphone, the sound wave moves the diaphragm. When the diaphragm vibrates, the poly coils move in the magnetic field, producing a varying current in the coil through electromagnetic induction.

As can be seen in Figures 10A and 10B, the poly coil mechanism can be readily used with phonograph cartridges. Thus, as opposed to the poly coil pickup systems, the poly coil speaker system as shown in figure 10A is geared towards producing a wide range of sound by readily controlling the overall "length" and "width" of the coils within the phonograph cartridge system of the present invention. ¹

As can be seen in Figures 10A and 10B the use of a poly coil mechanism according to the present invention is readily achieved in both "moving coil" phonograph cartridges and "moving magnet" phonograph cartridges in which the needle is readily pivotally displaced on the needle axis, thereby altering the field of the poly coils and producing the enhanced sound.

It is envisaged that either a fourth "bridging" control 260 of figure 1 OA, a fifth "bridging" control 190 of figure 10B or both fourth "bridging" control 260 of figure 10A and second "bridging" control 190 of figure 10B are situated in a location selected from the group consisting of: within poly coil matrix, externally to poly coil matrix or in adjacency to poly coil matrix. It will be appreciated that the above descriptions are intended to only serve as examples, and that many other embodiments are possible within the spirit and scope of the present invention.
