MUSICAL INSTRUMENT HAVING EXCHANGEABLE COMPONENTS CROSS-REFERENCE TO RELATED APPLICATIONS [0001] Embodiments of the present invention relate to U.S. Provisional Application Serial No. 60/386,365, filed June 6, 2002, entitled "Stringed Musical Instrument," which is hereby incorporated by reference herein and is a basis for a claim of priority. BACKGROUND [0002] Field of the Invention [0003] The present invention relates to the field of musical instruments and, in particular, to musical instruments having components that can be exchanged for other components. [0004] Description of Related Art: [0005] Innovation in the musical instrument arts is relatively infrequent. The basic design of many musical instruments has not changed in several hundred years. For example, the modern violin has essentially the same basic design today as it did in the 16th century. The basic design of a piano as we know it today is relatively unchanged today from its beginnings in the early 18th century. The same can be said for many woodwind and brass instruments also. [0006] One of the last true innovations in the musical instrument arts occurred in the 1940s and 1950s, when the pioneering work of Les Paul and Leo Fender transformed the guitar from an acoustic instrument to an electric instrument. In a modern electric guitar, magnetic "pickups," formed by winding a coil around magnetic pole pieces, sense vibrations from metal strings on the guitar, portions of which are located within the magnetic field of the pole pieces. The vibration of the metal strings modulates the magnetic field of the pole pieces, which, in turn, induces a current signal in the windings of the coil. This signal is sent to an electronic amplifier, which amplifies the signal into an audible sound. [0007] Guitar players can change the sound produced by an electric guitar by changing the guitar's pickups, which are available in a wide variety of styles and with a wide variety of tonal characteristics. However, the sounds generated by a guitar begin with a vibrating string. Although a guitar's pickup may affect how the vibrations of the guitar strings are processed, the structural characteristics of the guitar itself are what determine the nature of the string's vibration and, consequently, the tonal qualities or timbre of the guitar. Thus, legendary electric guitars such as the Gibson LES PAUL and the Fender STRATOCASTER and TELECASTER have unique tonal characteristics not only because of the particular type of pickups used on those guitars, but also because of the unique structural design and shape of the guitars themselves. [0008] One drawback of modern musical instruments is the static nature of the structure of the instrument. Traditionally, if a musician purchased, for example, a violin having a particular timbre or tonal quality, the sound, looks and. ergonomics of that violin could not be changed. The sound of the violin would be dictated primarily by the structural characteristics of the violin, which would remain static and unchanged. If the musician ultimately became bored or disenchanted with the sound of that particular violin, the musician had no alternative but to purchase another violin. The same can be said for other instruments. This is one reason why so many musicians traditionally have painstakingly taken a vast amount of time when purchasing a new instrument. A musician has had to make sure that he or she is completely happy with the sound of that instrument, be it a violin, piano, guitar, woodwind, horn or other instrument, because once a purchase has been made, the musician has been "stuck" with the sound, looks and ergonomics of that instrument. SUMMARY [0009] Embodiments of the present invention relate to musical instruments having exchangeable components. Embodiments of the present invention allow a musician to alter the tonal qualities, looks and ergonomics of a musical instrument simply by exchanging one or more components of the instrument with other components. Embodiments of the present invention also allow a musician to alter the aesthetic elements of a musical instrument simply by exchanging one or more components of the instrument with other components. Embodiments of the present invention also allow a musician to alter the tonal qualities of a musical instrument simply by exchanging one or more electrical or electronic components of the instrument with other electrical or electronic components.

[0033] Embodiments of the present invention are not Limited to stringed musical instruments, however. Embodiments of the present invention may also be adapted to woodwind instruments, such as, for example, piccolos, flutes, oboes, clarinets, recorders and bassoons, and the like, and horn instruments, such as, for example, trumpets, French horns, trombones, tubas, saxophones, and the like. Embodiments of the present invention may also be adapted to percussion instruments, such as for example, marimbas, vibraphones, drums, symbols, timpani, glockenspiel, woodblock, chimes, shakers and the like. [0034] A musical instrument having exchangeable components 10 according to an embodiment of the present invention is shown generally in Figure 1. A perspective view of the musical instrument having exchangeable components 10 according to an embodiment of the present invention is shown in Figure 2. The musical instrument having exchangeable components 10 shown in Figure 1 is a guitar and may include, for example, a core portion 18 and a body portion 11, the body portion 11 having a first body section 12a and a second body section 12b. The first body section 12a and the second body section 12b may be removably attached to the core portion 18 using one or more removable fasteners, such as, for example, screws. [0035] The body portion 11 may take a variety of shapes and sizes. The body portion 11 may be formed as a single component or may be formed as two or more components. According to an embodiment of the present invention, a plurality of body sections forming a body portion may be removably attached to one or more core portions to form a musical instrument. In the embodiment of the present invention shown in Figure 1, the body portion 11 is formed from two separate pieces, first body section 12a and second body section 12b, which are removably attached to the core portion 18. [0036] The first body section 12a and the second body section 12b may be contoured in a variety of ways. The contour of the first body section 12a and the second body section 12b may be dictated by a timbre or tonal characteristics desired by the user, or may be dictated by appearances or ergonomics desired by the user. For example, the contour of the first body section 12a and the second body section 12b may be formed to enhance or attenuate one or more frequency bands capable of being produced by the guitar. The contour of the first body section 12a and the second body section 12b may be formed to attenuate higher frequencies and enhance lower frequencies, for example, or may be formed to enhance higher frequencies and attenuate lower frequencies. [0037] The first body section 12a and the second body section 12b may be designed to achieve a wide variety of voices. For example, according to an embodiment of the present invention, the first body section 12a and the second body section 12b may be designed to form a hollow sound chamber, similar to those found in acoustic guitars. The hollow sound chamber may be the result of two hollow pieces joined together or, in an. alternative embodiment, may be formed from a single hollow piece which attaches to the core portion. [0038] According to another embodiment of the present invention, the first body section 12a and the second body section 12b may be designed to form a semi-hollow sound chamber, similar to those found in electric-acoustic guitars or semi-hollow body electric guitars. The semi-hollow sound chamber may be the result of two semi-hollow pieces joined together or, in an alternative embodiment, may be formed from a single semi-hollow piece which attaches to the core portion. [0039] According to another embodiment of the present invention, the body portion 11 may be designed to accommodate electrical or electronic components, such as, for example, pickups, transducers, switches, controls, lights and the like. The electrical or electronic components may be stand-alone within the body portion or may be integrated into the body portion 11 in such a way that they interface with one or more components located on the core portion 18. For example, additional pickups having unique tonal characteristics may be integrated into the body portion 11 and may interface to pickup electronics located on or within the core portion 18. [0040] In addition, the first body section 12a and the second body section 12b may be formed simply for aesthetic purposes, for looks or appearances, or for ergonomics. The first body section 12a and the second body section 12b may be formed in a more traditional manner or may be formed in a manner highly unusual for the instrument. [0041] In the embodiment of the present invention shown in Figure 1, the first body section 12a may include a first channel 14a and the second body section 12b may include a second channel 14b. The first and second channels 14a, 14b provide, inter alia, unique resonant characteristics for the first and second body sections 12a, 12b which, in turn, provide unique vibrating characteristics to the strings (not shown) of the guitar. The unique vibrating characteristic of the strings can then be sensed by pickups on the guitar, which can then send a signal representing the unique vibrating characteristics of the strings to an amplifier to produce an audible sound having unique tonal qualities. In addition, the first and second channels 14a, 14b provide, inter alia, an. area in which to place or insert one or more ribs 16 or other resonance enhancing or resonance altering structures. The ribs 16 may transfer vibration within, the first body section 12a and the second body section 12b in a unique way, thus resulting in unique tonal characteristics for the instrument. According to an embodiment of the present invention, the first body section 12a and the second body section 12b may attach to the core portion 18 using fasteners that extend through the ribs 16. [0042] According to embodiments of the present invention, the core portion 18 may be formed in a variety of ways. For example, the core portion 18 may be a single part or may be formed from a plurality of parts joined together. For example, in the embodiment shown in Figure 1, the core portion 18 is a guitar neck that may be a single piece carved from wood, a portion of which is surrounded by the first body section 12a and the second body section 12b. Alternatively, the core portion 18 may be a guitar neck formed from two or more separate and distinct pieces. For example, the core portion 18 may be a guitar neck and body piece formed from a neck having frets and fret wires and a body accommodating pickups and other electronics. The core portion 18 may also include a head stock 20 and tuning pegs 22 at a first end of the core portion and pickups 24 and a bridge 26 at a second end of the core portion. [0043] Other items peculiar to a particular instrument may also be included with the core portion 18. For example, if the core portion 18 is a guitar neck and body piece, the core portion may include tone controls, volume controls, pickup selector switches, a cord socket, battery compartments, and the like. Also, if the core portion 18 is a guitar neck and body piece, the guitar neck may include a fretboard and fret wires., a headstock with tuning machines, and a section for pickups and other electronics. [0044] An exploded view of a musical instrument having exchangeable components 10 according to an embodiment of the present invention is shown in Figure 3. The first body section 12a and the second body section 12b Eire formed as two distinct parts that may attach to, or be annexed to, the core portion 18. According to the embodiment of the present invention shown in Figure 3, the core portion 18 is a single part to which the first body section 12a and the second body section 12b to form a musical instrument having unique tonal characteristics and a unique voice. [0045] The first body section 12a and the second body section 12b may attach to the core portion 18 in a variety of ways. A method of attaching the first body section 12a and the second body section 12b to the core portion 18 according to an embodiment of the present invention may be seen in Figure 4. The first body section 12a and the second body section 12b may be provided with attachment points 30 through which fasteners, such as screws, for example, may be extended to arrive at an anchoring point on the core portion 18. If desirable, the fasteners may also extend through the ribs 16 prior to arriving at an anchoring point on the core portion 18. [0046] A musical instrument having exchangeable components 32 according to an embodiment of the present invention in which the body portion 13 is formed as a single component is shown in Figure 5. In Figure 5, the core portion 18 may be placed into a positioning area 40 existing within the body portion 13. The core portion 18 may attach to the body portion 13 in a variety of ways, such as, for example, using fasteners as was shown in Figure 4. [0047] A musical instrument having exchangeable components 34 according to another embodiment of the present invention in which a body portion 15 is formed from a first body section 50a and a second body section 50b is shown in Figure 6. In Figure 6, the core portion 18 may be placed into a positioning area 42 existing within the first body section 50a and the second body section 50b. The core portion 18 may attach to the body portion 15 in a variety of ways, such as, for example, using fasteners as wais shown in Figure 4. [0048] A musical instrument having exchangeable components 23 according to another embodiment of the present invention in which a body portion is formed from a first body section 17a, a second body section 17b and a third body section 17c is shown in Figure 7. In Figure 7, the first body section 17a, the second body section 17b and the third body section 17c may attach to the core portion 18 in a variety of ways, such as, for example, using fasteners as was shown in Figure 4. [0049] A body portion having a first body section 21a and a second body section 21b is shown in Figure 8. In Figure 8, the first body section 21a and/or the second body section 21b may include an area 25 into which a core portion may be received. In the embodiment of the invention shown in Figure 8, the first body section 21a and the second body section 21b form a "clam shell" around a core portion. The first body section 21a and the second body section 21b may attach to a core portion in a variety of ways, such as, for example, using fasteners as was shown in Figure 4. [0050] An enhanced view of the ribs 16 that may be placed into the first and second channels 14a, 14b according to an embodiment of the present invention is shown in Figure 9. The ribs 16 may be designed for a variety of reasons and may take a variety of forms in addition to the form of the ribs shown in Figure 6. For example, according to an embodiment of the present invention, the ribs 16 may be designed to provide resonance altering or resonance enhancing characteristics of the guitar. According to another embodiment of the present invention, the ribs 16 may be designed to provide structural support for the first body section 12a and the second body section 12b. In yet another embodiment of the present invention, the ribs 16 may be designed for aesthetic or visual impact. [0051] An isolated view of a core portion 18 according to an embodiment of the present invention is shown in Figure 10. In the embodiment shown in Figure 10, the core portion 18 is a guitar neck. The core portion 18 according to the embodiment shown in Figure 10 includes, but is not limited to, a bridge 26 to which strings (not shown) may be attached and pickups 24 for sensing the vibration of the strings. The core portion 18 shown in Figure 10 also includes, but is not limited to, controls 60 for adjusting parameters, such as, for example, tone and volume, and a selector switch 62 for selecting a pickup 24. In the embodiment shown in Figure 10, the core portion 18 is a single component. However, according to other embodiments of the invention, the core portion 18 may be a plurality of sections attached together to form one component. [0052] The core portion 18 shown in the embodiment in Figure 10 may include a plurality of pickups or, if, according to an embodiment of the present invention, the core portion 18 is the neck of an acoustic guitar, it may have no pickups. Moreover, all of the electronics and mechanical components included with the core portion 18 may be designed to be removably attached to the core portion 18 in a fashion similar to the removably attachable body portion. Thus, in addition to modifying the timbre or tonal characteristics of the instrument by exchanging body portions, a musician may also adjust the timbre or tonal characteristics of the instrument by exchanging electronic components. In addition, mechanical components such as, for example, the controls 60 and selector switch 62 may be designed to be exchanged onto different portions of the core portion 18. Thus, for example, if a musician did not like the position placement of the controls 60 and selector switch 62 on the core portion 18 as shown in Figure 10, the musician could remove the controls 60 and selector switch 62 on the core; portion 18 as shown in Figure 10 and exchange them for controls and a selector switch that are beatable in a different position on the core portion 18. The musician could also remove the controls 60 and selector switch 62 on the core portion 18 and exchange them for controls and a selector switch that has a feel or look more to the musician's liking, if so desired. [0053] An isolated view of a core portion 70 according to another embodiment of the present invention is shown in Figure 11. In the embodiment shown in Figure 11, the core portion 70 is a guitar neck. In addition, the core portion 70 shown in the embodiment of Figure 11 is formed from a first core section 72a and a second core section 72b. The first core section 72a is removably attached to the second core section 72b by one or more fasteners 74. The fasteners 74 may be any of a variety of fasteners common in the industry, such as, for example, screws. [0054] According to the embodiment of the present invention shown in Figure 11, a musician who is happy with the timbre or tonal characteristics of a particular body portion but would like to change the timbre or feel of the core portion 70 could exchange the first core section 72a with another first core section. [0055] Figure 12 shows a cross-sectional view through a rib 16 of an embodiment of the present invention shown in Figure 1. In Figure 12, the first body section 12a and the second body section 12b attach to the core portion 18 through attachment points 30 using fasteners 31. It can readily be seen in Figure 12 that the first body section 12a and the second body section 12b are "open ended." In addition, in the embodiment of the invention shown in Figure 12, the first body section 12a and the second body section 12b are of a thin wall construction, thus rendering the entire body area substantially hollow except in the area of the ribs 16. [0056] Figure 13 shows another cross-sectional view adjacent a rib 16 of an embodiment of the present invention shown in Figure 1. In Figure 13, a portion of the core has a hollow area 19 that may be used to house electronics or other items desired by the musician for use of the instrument. [0057] Referring back to Figure 1, according to an embodiment of the present invention, the body portion 11 may be made from a variety of materials. For example, the body portion 11, may be made from wood, metal, plastic, carbon fiber, a composite material and the like. In addition, the body portion 11 may be made from a combination of materials. For example, various parts of a body portion 11 formed as a single component may be made from different materials. According to another embodiment of the present invention, different sections of a body portion may be made from different materials. For example, the first body section 12a may be made from one material, such as carbon fiber, and the second body section 12b may be made from another material, such as a composite. [0058] In addition, other components of a musical instrument having exchangeable components 10 may also be made from a variety of materials. For example, the core portion 18 and the ribs 16 may be made from wood, metal, plastic, carbon fiber, a composite material and the like, or a combination of materials. According to an embodiment of the present invention, if the core portion 18 is a guitar neck, the core portion 18 may be made from woods such as maple, rosewood, ebony or a combination of these woods. [0059] A musical instrument having exchangeable components 80 according to another embodiment of the present invention having a core portion 82 and a body portion 84 is shown in Figure 14. In the embodiment shown in Figure 14, the musical instrument is a trumpet. The body portion 84 may be removably attached to the core portion 82, thereby allowing a musician to change the timbre or tonal characteristics of the instrument simply by exchanging body portion 84 for another body portion 84. In the embodiment shown in Figure 14, the body portion 84 includes two separate components; however, according to embodiments of the present invention, the body portion 84 may include one component, two components or a plurality of components. [0060] The advantages of embodiments of the present invention may readily be seen. By having a variety of body portions available, a musician may be able to alter the timbre or tonal characteristics of an instrument simply by removing one or more body portions and exchanging them with others. Thus, rather than having an arsenal of instruments each having a unique timbre or tonal characteristic, a musician may retain one core portion and a plurality of body portions. [0061] Embodiments of the present invention provide numerous advantages over the prior art. For example, guitar players become particularly attached to the feel and playability of the necks of their guitars, i.e.., the core portion of their guitar. Guitar players typically have a "favorite guitar" that always "feels" good to them, thus enhancing their playing and providing for an enhanced musical experience. According to embodiments of the present invention, a guitar player may find a favorite core portion, i.e., a favorite neck, one that agrees with the guitar player from a feel and playability standpoint, and retain that core portion and use it with a plurality of body portions. Thus, a guitar player may change the timbre or tonal characteristics of the guitar without having to lose that "favorite" guitar feel, simply by retaining the core portion of the guitar but exchanging body portions. [0062] Other musicians will find similar advantages with embodiments of the present invention. For example, woodwind and horn players may become particularly fond of a particular embouchure, keys or pads. Using embodiments of the present invention, a woodwind or horn player may retain a core portion, such as, for example, a main sound chamber having keys and a mouthpiece, and exchange various body portions that alter the structural characteristics of the sound chamber to change the timbre of the instrument. Thus, the woodwind or born player may continue to enjoy the feel of the embouchure, keys or pads, for example, while greatly expanding the tonal characteristics of the instrument. [0063] While particular embodiments of the present invention have been shown and described, it will be obvious to those skilled in the art that the invention is not limited to the particular embodiments shown and described and that changes and modifications may be made without departing from the spirit and scope of the appended claims.
