The present technology is a plectrum or pick that includes at least two layers that have long vectors and at least one layer that is amorphous, wherein the layers are laminated together. More specifically, the present technology is a laminated pick that provides two tips, which in use, one with the long vector normal to the strings and one with the long vector parallel to the strings.
Guitar picks are often used when a musician is playing a guitar. The pick is held between the thumb and first finger. There is a rounded proximal end and a pointed distal end. This pointed distal end is used to deflect and release the guitar strings. Picks are commonly made of synthetic materials and may be stiff or flexible. Some designs include multiple round apertures as design features. Others, such as disclosed in U.S. Pat. No. 7,459,620, provide a central opening which is slotted open to permit the pick to be stored on pegs and posts on the guitar. The guitar pick is formed of flexible synthetic polymeric material and has a pick point for picking the guitar strings. The body of the guitar pick is sufficiently large to hold between the thumb and forefingers for its manipulation. The body has a central opening that has smooth profile walls and is slotted away from the pick point. The central opening and the slot, together with the flexibility of the pick is sufficient to permit it to be snapped onto and off of pegs and posts on the guitar for storage and retrieval. It is stated that the aperture with its smooth profile walls also permits the musician to firmly and comfortably grasp the pick. The use of a single layer in constructing the pick results in inferior sound, wear in and tone. Further, the slotted opening significantly reduces the strength of the pick, predisposing it to break along an axis defined by the slot. Still further, smooth profile edges on the opening do not contribute well to the user being able to grasp the pick.
Another approach to storage and reduction of slippage is disclosed in U.S. Pat. No. 6,835,881. A guitar pick having a key ring hole for selective attachment to a key ring, and also having a centrally-located disc constructed from non-slippery material, in order to prevent the pick from slipping from a user's fingers while the pick is being used to play a guitar. The disc is substantially flush with the front surface of the pick. The key ring hole is lined on both the front and rear surfaces of the pick with a raised bushing, in order to prevent the key ring hole from cracking or splitting after repeated use. When not being used to play a guitar, the guitar pick may be stored upon the key ring, in order to prevent the pick from becoming misplaced. The opening is not for assisting a user to grasp the pick. Although the disc is supposed to assist in the user grasping the pick, the material used for the disc is not disclosed. No attempt is made to improve the quality of sound, flexibility, tone and wear in of the pick.
Picks that are made from synthetic materials tend to produce an inferior sound. This can be improved by taking steps to alter the flexibility of the pick edges. In U.S. Pat. No. 4,228,719 a pick that has a plurality of rounded corners each adapted for selectively engaging the strings of a musical instrument and each having a degree of flexibility different from that of the others is disclosed. Resilient plastic is molded into a single piece with holes adjacent at least two of the playing corners with the holes being of different sizes so that the playing corners have different flexibility. No attempt is made to improve the quality of sound, flexibility, tone and wear in of the pick.
Wood picks provide a superior tone and volume, however, they tend to crack unless they are thick. The thicker the pick, the less flexible it is, and hence the advantages in terms of tone and volume are lost. Plywood picks are brittle and crack easily.
United States Patent Application 20140090540 discloses a pick for a stringed musical instrument, the pick having a substantially triangular shape and a top edge and two side edges that converge toward a tip. The tip may be used for strumming or picking a stringed instrument. The projection extends from one of the two side edges and contains an enlarged head disposed on its distal end. The enlarged head may be used for tapping or hammering the strings of a musical instrument. In use, the pick may be grasped along the top edge for strumming or picking and it may be rotated approximately ninety degrees to place the head on the projection into contact with strings on the musical instrument while the user grasps the other side edge. The pick is made of a plastic polymer or nylon. No attempt is made to improve the quality of sound, flexibility, tone and wear in of the pick.
United States Patent Application 20130104722 discloses a multi-purpose plectrum that includes a first lobe, a second lobe, a third lobe, a recessed edge, and a convex edge. Grasping the plectrum with the recessed edge resting against the web between the thumb and forefinger of a user's hand allows the user to strum or pluck a string of a string instrument with either the third lobe or the convex edge. The plectrum may also be grasped to allow a user to strum or pluck one or more strings of a string instrument with the first lobe and the second lobe. No attempt is made to improve the quality of sound, flexibility, tone and wear in of the pick.
United States Patent Application 20100180748 discloses a plectrum or pick that is used to strum or pick the strings of guitars, bass guitars, ukuleles, mandolins or other stringed instruments. This pick has apertures disposed therethrough at predetermined locations. Such apertures provide a gripping means which enables a user to grasp and control such pick. The device makes it less likely that a user will drop or lose his or her pick while playing. The apertures provide finger to thumb contact, allowing the musician to better manage the pick in their hands. The apertures may be surrounded by a rim to improve grip. The pick are made of plastic, metal or a combination thereof—it is not disclosed how a combination would be used. No attempt is made to improve the quality of sound, flexibility, tone and wear in of the pick.
DE102006054252 discloses plectra with a wide range of aperture shapes. These are to improve the user's grip. Also disclosed are plectra made of three layers. The inner layer is disclosed as potentially being a precious stone, or a gel or a rubber member. The inner layer is also disclosed as a central support layer made of several different materials. Further, it is disclosed that the inner layers, if of different colours can be visible as in plywood (but are not plywood). Particularly steel (silver, platinum) and gold layers can be used. Precious metals are also suitable so that jewellery is the usable functional element. It is known that gold or other precious metals can generate a special advantageous sound. The objective of these plectra are to improve the user's grip and for the plectra to be decorative or function as jewellery. Little or no attention is paid to improving quality of sound, flexibility, tone and wear in of the pick by selection of long vector direction or long vector layers.
What is needed is a laminated pick that provides excellent grip for the user, is flexible, has very good “wearing in” attributes and can be customized. Preferably, the layers of the laminated pick would be arranged so that the grains of the layers have specific orientations relative to one another. It would also be preferable if the effective thickness of the pick could be altered by altering the grain direction. Preferable, the pick would provide at least two pick contact tips or contact surfaces that provide different tones or attacks. Preferably, the tip of the pick would be dipped or otherwise coated in a layer that would make the tip either softer, for use with a ukulele, where a soft sound is desired, or harder, for when a harder sound is desired. It would be desirable for the pick to have a small slotted aperture for hanging the pick on a string, while not impacting on the integrity of the pick. Also preferably, the picks would be provided on point-of-sale cards.
The present technology utilizes specific orientations of the grain of layers of wood veneer coupled with an amorphous layer to provide picks with superior flexibility, wear in, and tone. Parallel orientation of the grain results in a very flexible pick, while perpendicular orientation provides more rigidity. Using layers of wood having different densities or hardness allows for contact surfaces having different characteristics. For example, using a soft wood on a first side and a harder or more dense wood on a second side would provide a hard attack on the first side and a warm attack on the second side. A further attribute of the pick is attained by having more than one pick point. Having a first pick point at the end of the body and a second pick point on the side of the body combined with specific orientations of the grain of the wood veneer results in pick points with different characteristics. For example, if the grain of the wood is oriented along a longitudinal axis of the body of the pick, then the first pick point will be more rigid than the second pick point. Similarly, the “effective thickness” of a pick can be altered by altering the direction of the grain. If the grain is parallel to the longitudinal axis the pick will have a thicker effective thickness and if it is normal to the longitudinal axis it will have a thinner effective thickness. By coating the pick point the characteristics of the pick can be altered to being a softer attack or a harder attack, while retaining the characteristics of wood.
In one embodiment, a pick for use with a musical instrument is provided, the pick comprising at least three layers, an upper layer having a long vector, a lower layer having a long vector and an at least one amorphous layer, the long vectors aligned with a longitudinal axis of the pick, the upper layer and the lower layer sandwiching and adhered to the at least one amorphous layer to provide a flexible, resilient pick. The pick may have two pick points, normal to one another. As the direction of the long vector controls the feel of the pick, the first pick point will be more rigid and the second pick point will be more flexible. This also causes the first pick point to feel thicker and the second pick point to feel thinner, despite being substantially the same thickness. These features manifest themselves as differences in tone and attack.

A vector aligned with the length of the fibers or grain. For example, the long vector of a carbon fiber reinforced polymer is aligned with the long fibers, noting that substantially all the long fibers are arranged in one specific orientation and are not randomly arranged. Similarly, the long vector of a fiberglass reinforced polymer is aligned with the long fibres, noting that substantially all the long fibers are arranged in one specific orientation and are not randomly arranged. The long vector in wood is aligned with the length of the grain of the wood. The long vector is used when there are macroscopic differences in a material such that you can define a directionality.
A long vector layer is a layer or veneer in which a directionality of the fibers or grain, or the like can be identified. It may include, but is not limited to natural wood, carbon fiber reinforced polymer and fiberglass reinforced polymer veneers. It does not include materials such as oriented strand board, which would be considered as a “non-natural” wood, nor does it include carbon fiber or fiberglass reinforced polymer veneers that lack a long vector.
An amorphous layer or veneer is one in which no directionality of the fibers or a grain can be determined (in other words, a disorganized fibrous material) or has no fibers. It may include, but is not limited to paper, cardboard, plastic polymer, urethane, silk, brass, nylon, polyoxymethylene and particle board. The paper material may be made with natural or synthetic fiber, for example, cellulose fibers or plastic fibers. Carbon fiber reinforced polymers and fiberglass reinforced polymers can also be amorphous. The amorphous layer imparts a “toughness” to the pick. It has equal flexibility in all directions and resists cracking when flexed. The amorphous layer is about 1 mm to about 0.4 mm thick, preferably 0.2 mm and all thicknesses therebetween.
A structural amorphous layer is one that can be used as one layer of a two layer pick. It includes materials such as brass, plastic polymers, nylon, polyoxymethylene, but does not include materials such as paper that would be readily broken down if contacting the strings. Carbon fiber reinforced polymers and fiberglass reinforced polymers can also form the structural amorphous layer. Polyoxymethylene is an especially suitable structural amorphous layer as it has a low coefficient of friction, resists abrasion and is hygroscopic, although only mildly hygroscopic. The structured amorphous layer is about 1 mm to about 0.4 mm thick, preferably 0.2 mm and all thicknesses therebetween.
A tip coating is a layer that substantially covers the tip and the region in the vicinity of the tip. The tip may be dipped in the coating material. The tip coating can be a soft material, such as, but not limited to silicone or a hard material that includes a filler. The hard materials include, but are not limited to amorphous (chopped or milled for example, but not limited to) carbon fiber reinforced polymer or directional carbon fiber reinforced polymer, amorphous fiberglass fiber reinforced polymer (chopped or milled for example, but not limited to) or directional fiberglass fiber reinforced polymer, graphite in polyurethane, or ground metal, metal powder, or metal filings in a polymer such as polyurethane. An exemplary mixture for hardening the tip is J-B Weld®, which is an epoxy with ground metal or metal powder. It provides a tensile strength of 3960 PSI. Carbon nanotubes, beads, glass beads, plastic beads, and ferrous materials to impart magnetism can also be provided in a plastic polymer to provide a hard material. The tip coating allows for a change in the feel and sound of the pick to one of either softer or harder, while retaining the flexibility of the combination of the long vector layer or layers and the amorphous layer or layers in the remainder of the pick. The tip coating is applied to the tip, or the body in the vicinity of the tip and the tip, or as much as the tip, and the body between the tip and the central aperture. It is preferably applied by dipping the pick in the coating. It similarly can be applied to a pick made of a structural amorphous layer and a long vector layer.
The effective thickness of a pick is based on the characteristics of a plastic polymeric pick, including the flexibility of the pick. The effective thickness of the pick can be altered by altering the orientation of the long vector layer and through the use of softer or harder woods. Orientation of the long vectors to be parallel to a longitudinal axis of the pick will make the effective thickness greater, while orientation of the long vectors normal to the longitudinal axis of the pick will decrease the effective thickness, relative to the actual thickness of the pick.
In developing the present technology, various combinations of wood veneers were used in various orientation. It was found that if the veneers were glued together, the resultant picks cracked easily, and did not produce the desired tone or wear in characteristics. When an amorphous layer was used in the pick construction, these deficiencies were remedied and the resultant picks had the desired characteristics. The wood veneers were found to have differing flexibilities depending on their orientation relative to the longitudinal axis of the pick. It was found that the grain orientation was the significant parameter, and this was found to be generically, the long vector, as non-wood veneers were also found to have differing flexibilities depending on their orientation relative to the longitudinal axis of the pick. Testing of various amorphous materials and veneers demonstrated that use of hygroscopic materials provided an additional advantage of reducing slippage of the pick in the user's fingers. Non-hygroscopic materials can slip from the user's fingers as the user's fingers usually sweat during playing of the instrument. Wood veneers, polyoxymethylene, polyethylene terephthalate, paper material, and polyvinyl acetate were found to be suitably hygroscopic. As would be known to one skilled in the art, other materials could also provide the desired characteristics.
To summarize, the veneer layers have a long vector that results in flexibility or rigidity depending upon the direction that the long vector is in relation to the longitudinal axis of the pick. They are hygroscopic. The amorphous layer has no vectors and provide resiliency. They are hygroscopic. The structured amorphous layer has the additional feature of being resistant to wear and abrasion. The combinations of the veneer layers and the amorphous layers provide a warm or hard attack, the desired tone and good wear in.
A pick for a musical instrument, generally referred to as 6 is shown in
A centrally located aperture 34 in the body 8, has an irregular perimeter 36, with angular direction changes resulting in points 42 or jags or fingers extending into the sides 38, 40. In the disclosed embodiment, the aperture 34 defines a maple leaf. This has a plurality of direction changes that include right angles, acute angles and obtuse angles for a total of 26 angle changes. As shown in
The pick 6 is a uniform thickness between about 0.3 mm deep to about 3 mm deep and all thicknesses therebetween. The dimensions for the length and breadth are about 15×15 mm or about 40×40 mm and all ranges therebetween. The aperture 34, while being irregular, can be measured to be about 3 to about 5 mm in diameter or about 4 mm in diameter or about 8 mm in diameter, and all ranges therebetween.
The depth of the pick 6 allows it to withstand the force of a user playing a string, while at the same time providing for the desired flexibility. The central aperture 34 further contributes to the flexibility, allowing the depth to be somewhat thicker than it would be to provide the resultant flexibility. The use of wood also contributes to the flexibility. The result is a pick 6 that provides a warm pick attack, a louder tone than a synthetic pick or plastic polymer pick and good wear-in attributes.
The pick 6 provides superior grip for the user. This is in part a result of the central aperture 34 with its irregular perimeter 36. A user's finger and thumb can press against each other in the aperture to provide one aspect of the superior grip—doing so against an irregular perimeter greatly enhances the grip. Without being bound to theory, this is a result of the large perimeter 36, relative to a shape, for example, such as a circle. Using 8 mm diameter as an example, one can see that the length of the perimeter is at least about 1.25 or about 1.44 times that of a circular aperture defined as having a diameter equivalent to the widest point of the pick (36.3 mm for the perimeter and a circumference of 25.12 mm). This means that the irregular perimeter provides a much longer edge than would a simple shape such as a circle, and this edge provides a gripping surface. One can clearly see that the ratio of perimeter to area of the central aperture is higher for the central aperture with an irregular perimeter than it would be for a circular aperture or a square aperture having a diameter of 8 mm or width of 8 mm, respectively.
The circularity of a circle is 1 and the circularity of a complex shape can approach 0. The circularity of the central aperture is between about 0.0 to about 0.6 or about 0.1 to about 0.4, or about 0.2 to about 0.3 and all ranges therebetween.
The superior grip is also a result of the angular direction changes 42 in the perimeter 36 that result in a complex geometric shape, thereby providing gripping surfaces. Another contributor to grip is the surface contour 44, which is a result of the wood grain or the long vectors in other veneers.
As shown in
In the preferred embodiments, the pick 6 is made from natural wood veneer, which may be, for example, but not limited to maple, spruce, cedar, mahogany, rosewood, sapele, cherry, koa, alder, walnut, basswood, agathis, or poplar and an amorphous material in one or more layers. In other embodiments, other materials may be used, for example, carbon fibre reinforced polymer or fibreglass reinforced polymer or the like—essentially any suitably flexible and strong material in which a long vector can be defined that impacts on the rigidity and flexibility of the material, with alignment of the long vectors leading to flexibility and arrangement of the long vectors normal to one another results in rigidity.

In another embodiment, a different pick shape is provided, as shown in
The pick, generally referred to as 206 has a body, generally referred to as 208 with a proximal end 212, a first edge 214 and a second edge 216. The first and second edges 214, 216 converge to a distal end 218, which is the pick point or tip. Between the proximal end 212 and the first and second edges 214, 216 are a first shoulder 220 and a second shoulder 222 which are curved to a large radius. The proximal end 212 may be curved or straight. The first and second edges 214, 216 curve inward slightly towards the first distal end 218.
A centrally located aperture 234 in the body 208, has an irregular perimeter 236, with angular direction changes resulting in points 242 or jags or fingers extending into the sides 238, 240. In the disclosed embodiment, the aperture 234 defines a maple leaf. This has a plurality of direction changes that include right angles, acute angles and obtuse angles for a total of 26 angle changes.
As shown in
As shown in
The picks 6, 206 are preferably provided in effective thicknesses of 0.3 mm, 0.46 mm, 0.6 mm, 0.8 mm, 1.0 mm, 1.2 mm and in 0.2 mm increments to about 3 mm. A 0.6 mm pick can have an effective thickness of 0.46 mm or of 0.6 mm, by altering the orientation of the long vector layer or layers. If the orientation of the long vector layer or layers is parallel to the longitudinal axis 72, the pick 6 will have the same or similar thickness as effective thickness. If the orientation of the long vector layer or layers is normal to the longitudinal axis 72, the pick 6 will have an effective thickness of less than the actual thickness.
