Description

FIELD OF THE INVENTION [0001] The present invention relates to a stringed instrument for generating sound from two acoustic boards on opposite sides of a musical instrument,

The present invention relates to a string instrument such as a guitar, a violin or a banjo, which is arranged on opposite sides of the instrument using only a single set of strings connecting the bridges on each sound board through the hollow interior of the instrument Using a single set of strings interconnecting the bridges on each acoustic board through the hollow interior of the musical instrument, with the stringed instrument having a hollow or semi-hollow body for creating and controlling sound from the separate acoustic boards To a method of making a stringed instrument having a hollow or semi-hollow body for creating and controlling sound from each of two acoustic boards disposed on opposite sides of the body of the musical instrument.

A conventional stringed instrument having a hollow or semi-ball-shaped body produces a musical tone by twisting or tearing the strings tensioned on the bridge and saddle mounted on the acoustic board corresponding to the anatomical front of the musical instrument. Acoustics are generated by the vibrations of strings and propagated throughout the body of the instrument from the bridge assembly mounted on the acoustic board and are generally located within the anatomical front acoustic board and underneath the strings, hole.

In an acoustic guitar, the hollow interior of the body forms an acoustical resonant enclosure that enhances and amplifies the sound generated from the acoustic board. It is understood that the acoustic board of a musical instrument traditionally represents the top or front of the musical instrument. The rear or back of the guitar is not considered to have much importance, if any, compared to the overall sound generated by the musical instrument, and therefore little attention is paid to the wood used in the fabrication of the other rear boards. The front and rear boards are connected to the body of the musical instrument along the side of the musical instrument to completely enclose the body and to enclose the hollow interior. As described above, the front board is recognized as an acoustic board for acoustic guitars and is made up of expensive tone wood such as, for example, spruce and / or pencil jewelery, while the rear board is typically Which is made of low cost wood or other materials. The front and rear boards of conventional acoustic guitars typically include ribs on the inside of each board facing the inside of the guitar to add to the structural strength of each board. However, in most cases, there is no structural support between the front board and the rear board of a conventional acoustic guitar, other than the support provided by the side connecting the front board to the rear board.

According to the present invention, the sound generated from the stringed instrument is transmitted to the front acoustic board through the inside of the guitar by using a single set of other strings, by connecting the front acoustic board to the rear acoustic board, It has been found that it can be enhanced by using both acoustic boards simultaneously, including both rear acoustic boards. This includes first bridges and saddles mounted on the front acoustic board of the musical instrument and second bridges and saddles mounted on the rear acoustic board and a single set of other strings is connected to the first bridge and the saddle through the other hollow interior, Lt; RTI ID = 0.0 > bridge < / RTI > and saddle assembly interconnecting the two bridges. The dual bridge and saddle assembly preferably also provides additional structural support for the guitar between the front acoustic board and the rear acoustic board, respectively, and also provides additional structural support for the guitar between the front acoustic board and the rear acoustic board, And a support post connected between the first bridge and the second bridge through the inside thereof.

By vibrating a common set of strings that extend between two acoustic boards, acoustic is transmitted from both the front and rear acoustic boards of the musical instrument to the entire interior of the musical instrument so that other strings are generated differently from acoustic guitars connected only to the front acoustic board Generating a composition of acoustic sound with a strength and frequency range greater than the intensity and frequency range. Also, the sound is further enhanced by coupling each acoustic board to its own separate acoustic (pre) amplifier and / or amplifier, such that the sound generated from each acoustic board is independently and individually controlled .

According to the invention, at least one of the acoustic boards, preferably a front acoustic board, comprises, in addition to a conventional acoustic hall, at least one acoustic port through which sound can escape from the guitar independently of the acoustic hall Although it is also preferred, it is not essential. The acoustic port may be located generally in the vicinity of the acoustic hole and may be a hollow member of any desired geometry, preferably one of the acoustic boards, preferably a tube configured to be inserted through an opening formed in the front acoustic board Wherein the hollow member has a length that is equal to 5% to 95% of the distance between the front acoustic board and the rear acoustic board, extending from the front acoustic board to a predetermined position in the hollow body of the musical instrument, The opening of the size dimension, preferably a geometric shape round, through the front acoustic board is formed. By varying the extended length of the acoustic ports within the interior of the guitar, i. E. By selecting the desired length from a variety of different lengths within the desired range, respectively, depending on the intended sound, it is possible, for example, to vary the frequency spectrum of the sound exiting the acoustic hole The acoustic port may be tuned to a different desired frequency range proportional to the other resonant frequencies, so as to have a higher and / or lower frequency spectrum corresponding to a treble or bass sound range, to produce a larger dynamic frequency range generated by the musical instrument .

Also, one or more panels connected between the front acoustic board and the rear acoustic board for funneling sound toward the acoustic port (s), particularly when the acoustic port is added to the musical instrument, It is also desirable to include. The panel (s) should be arranged so as to extend generally up to the other upper bout (bout), but not limited to, between each acoustic port and the acoustic hole, preferably to the other neck, And may be interconnected with other panels near the neck of the guitar. In this arrangement, the panel causes the sound to be directed at each acoustic port in a directed manner, thereby causing the acoustic to exit the acoustic port (s) in addition to exiting the acoustic hole. Since the panel (s) are connected between the front acoustic board and the back acoustical board, the panel (s) can be mounted on the front and / or rear acoustical board in addition to the support provided by the use of support posts in the double bridge and saddle assembly Will provide structural support between the other front and rear boards, which serves as an alternative to the use of ribs and current standards.

The stringed instrument of the present invention includes a first acoustic board representing the front surface of the stringed instrument, a second acoustic board representing the rear surface of the stringed instrument, a common hollow or semi-hollow interior extending between the first acoustic board and the second acoustic board, A dual bridge and saddle assembly extending between the first acoustic board and the second acoustic board, the dual bridge and saddle assembly comprising a first bridge and saddle mounted on the first acoustic board, And a single set of strings interconnecting the first and second bridges of the dual bridge and saddle assembly through the common interior of the musical instrument.

The present invention also relates to a method and apparatus for use in a broadly hollow or semi-rigid interior, a front and rear acoustic board disposed on opposite sides of the interior, a first bridge and saddle for a single set of strings and a front acoustic board, 2 bridges and saddles, the method comprising the steps of: mounting a first bridge in a dual bridge and saddle assembly on a front acoustic board, And mounting a second bridge in the saddle assembly on the rear acoustic board and connecting the first bridge and the second bridge through the inner body of the musical instrument to generate sound from each acoustic board, To the musical instrument. Preferably, the method further comprises structurally connecting the first bridge in the dual bridge and saddle assembly to the second bridge using a support post to provide structural support between the front acoustic board and the back acoustical board, respectively .

The musical instrument of the present invention is exemplified by the acoustic guitar 10 as shown in Figs. 1 to 9, showing its preferred embodiment. The acoustic guitar 10 includes a main body 11 having a front acoustic board 12 as shown in Figure 1, a rear acoustic board 14 as shown in Figure 2, 8a, 8b, 9a, 9b, and 12, respectively, extending through the hollow or semi-hollow interior 18 of the body 11 from the front acoustic board 12 to the rear acoustic board 14. [ And more specifically a double bridge and saddle assembly 16 as shown. 3 and 4 and 6, which connect the front acoustic board 12 to the rear acoustic board 14 so as to completely surround the body of the guitar 10, Respectively.

The double bridge and saddle assembly 16 shown in Figure 8A that extends between the front acoustic board 12 and the rear acoustic board 14 includes a first bridge 20 mounted on the front acoustic board 12, A second bridge 22 mounted on the board 14, support posts 23 and 24 interconnecting the first bridge 20 to the second bridge 22, The saddle assembly 30 configured to be inserted into the slot 34 in the first bridge 20 and the saddle assembly 31 configured to be inserted into the slot 40 in the second bridge 22. [

A single set of strings 33 of custom length or elongated length is placed on the front acoustic board 12 along the neck 17 of the guitar 10 from the headstock 19 representing the upper end of the guitar 10 To the mounted first bridge 20 and from the first bridge 20 to the second bridge 22 mounted on the rear acoustic board 14 in the hollow interior of the body 11 of the guitar 10 18). One end of each string in the set of other strings 33 is connected to a tuning knob 15 in the headstock 19 and the opposite end of each string in the set of strings 33 is connected to a 2 bridge 22 so that a set of strings 33 interconnects the first bridge 20 to the second bridge 22 through the interior 18 of the guitar 10. The set of strings 33 preferably starts at a pegged position within the second bridge 22 on the rear acoustic board 14 as will be further described with reference to Figures 9b and 12, The saddle 44 inserted into the first bridge 20 into the first bridge 20 over the saddle 48 inserted into the other bridge 20 from which the set of strings 33 is connected to the neck of the guitar 10 17 to the tuning knob 15.

The support posts 23 and 24 in the dual bridge and saddle assembly 16 serve to secure and support the upper acoustic board 12 of the guitar 10 to the rear acoustic board 14 to provide front and / None of the boards 12, 14 will collapse from too much tension when the other string 33 is stuck. However, the use of the support posts 23, 24 is preferred, but not critical to the invention, because the structural support for preventing collapse of any one of the front or rear boards 12, 14, As will be later described in the discussion relating to the inclusion of the panels 80 and 82 with the use of the acoustic pods 70 and 72, respectively, regardless of the support posts 23 and 24 in the double bridge and saddle assembly 16. [ It is to be understood that it is achievable by using a different supporting member between the acoustic board 12 and the rear acoustic board 14. The support posts 23 and 24 in the dual bridge and saddle assembly 16 are preferably disposed at an oblique angle between the front acoustic board 12 and the rear acoustic board 14 as shown in Figure 8A , Whereupon the upper acoustic board 12 is positioned slightly toward the neck 17 of the guitar 10 relative to the position of the rear acoustic board 14. This arrangement relaxes some of the tension in the set of other strings 33 during the tuning of the guitar 10. The support posts 23, 24 may be made of any desired material construction, preferably a wood or wood replacement construct, and may have any desired geometric shape, including, for example, square, rectangular or cylindrical shapes.

The openings 35 in the first bridge 20 are aligned in a substantially horizontal plane which is transverse to the direction of the set of other strings 33. The slot 34 in the first bridge 20 may be positioned at an acute angle with respect to the horizontal, as shown in Figure 1, to facilitate and / or allow adjustment of other particular intonations. The first bridge 20 can match the geometry and dimensions of the second bridge 22 in the double bridge and saddle assembly 16, except for its width dimensions, in geometry and dimensions. The second bridge 22 preferably includes a first bridge 20 for receiving two sets of openings 38,39 for the other strings 33 as opposed to only one set of openings 35 Should have a width "d ", as shown in Figure 2, which is wider than the width of the bridge 20. [ The set of openings 39 in the second bridge 22 is used to fix and peg one end of each of the other strings 33 into the opening 39. The two sets of openings 38 and 39 should be arranged parallel to one another on the opposite side of the slot 40 in the second bridge 22 and the number of openings 35 present in the first bridge 20 Shall include the total number of openings corresponding to the ship.

The strings 33 are pegged into the openings 39 in the second bridge 22 using peg members 42 as shown in Figures 9b and 12, So that each peg member 42 is engaged with each string 33 in each of the openings 39 to engage each stringed mating end within one of the openings 39 . The other strings 33 are then moved from the pegged end in the openings 39 onto the saddles 48 in the saddle assembly 31 as shown in Figures 9b and 12 and on the saddles 48 in the openings 38 in the second bridge 22.

A jack 47 extending from the wire cord 46 is configured to attach the pickup device 45 to the preamplifier 60 mounted on the side 13 of the guitar 10 as shown in Fig. Similarly, the saddle assembly 31 insertable into the slot 40 in the second bridge 22 of the dual bridge and saddle assembly 16 includes the saddle 48, the pickup device 50, the wire cords 51, And an output jack 52 extending from the wire cord 51 for attaching the pickup device 50 to a separate preamplifier 62 which may also be mounted on the same side 13 of the guitar 10 . The two preamplifiers 60 and 62 are connected to the outlet jacks 60 and 62 which are mounted on the side 13 of the guitar 10, Each of the preamplifiers 60 and 62 may be connected to a separate amplifier (not shown) for controlling the sound from each preamplifier, Can be connected.

Each saddle assembly 30, 31 includes saddles 44, 48 and pickup devices 45, 50, respectively. The saddles 44 and 48 serve to support a set of other strings 33 on the first and second bridges 20 and 22 on the front and rear acoustic boards 12 and 14, respectively. Each of the saddles 44 and 48 may be a component of the independent saddle assembly 30 or 31 separate from the respective pickup device 45 or 50 or alternatively may be a component of one of the saddle assemblies 30 and 31 Both may have a pickup device 45, 50 integrated in the saddle assembly 30, 31 to form a single integrated unit that includes a combination of both saddles and pickups. The pickup device 50 in the saddle assembly 31 is configured to be inserted into the opening 57 formed in the saddle 48 to form an integrated unit while the pickup device 50 in the saddle assembly 30 May or may not be integrated in saddle 44 to form a single unit. 9B, the pick-up device 45 in the saddle assembly 30 represents an independent component and is therefore separately inserted into the slot 34 in the first bridge 20, Saddle 48 combined with the pick-up device 50 is inserted into the slot 40 in the second bridge 22 as one unified unit, while the saddle 48 combined with the pick-up device 50 must be inserted into the slot 34 on the pick- .

Whether the one or both saddle assemblies 30 and 31 are fabricated to form a single integrated unit that includes both the saddle and the pick-up device, the saddle components 44, 48 should have a configuration including a body portion 53, 55 and a thin section 54 extending outwardly from the body portion 53, 55. The thin elongated section 54 should have a substantially rectangular geometry so that each saddle 44 and 48 forms a "T" configuration in cross section, And the body portions 53 and 55 indicate the horizontal side. In addition, the thin section 54 extending from each saddle 44, 48 must have a width that matches the width of the slots 34, 40 in the first and second bridges 20, 22, respectively, The width of the body portion 53, The body portion 53 of the saddle 44 may have a conical geometry extending to a relatively sharp apex 56 configured to engage the other strings 33 on the front acoustic board 12, 48 may have a round semi-cylindrical configuration for simply engaging the other strings 33 on the rear acoustic board 14. [

The guitar 10 of the present invention includes at least one acoustic port 70 but is preferably two acoustic ports 70 and 72 as illustrated in Figures 1, 7 and 8a, The acoustic ports 70 and 72 are preferably formed in the front acoustic board 12 on the opposite sides of the acoustic holes 13 in the guitar 10. The acoustic holes 13 are located in the body 11 of the guitar 10, preferably in the front acoustic board 12, at positions below the other strings 33 and preferably in the respective acoustic ports 70, As shown in FIG. Each of the acoustic ports 70 and 72 preferably comprises a member 77, 78 in the form of a hollow tube configured to be inserted through an opening formed in one of the acoustic boards, preferably a front acoustic board, of any desired geometry, With the opening being shaped to accommodate the members 77,78. Each of the members 77,78 is configured such that the members 77,78 are positioned between 5% and 95% of the distance between the front acoustic board 12 and the rear acoustic board 14 from the front acoustic board 12 of the guitar 10. [ To extend into a hollow interior 18 of the same guitar 10 as the other members 77 and 78 so that each member 77 and 78 preferably has a desired geometry 74, which extend through each member 77, 78, preferably round, having a shape and size. By changing either the size of the openings 73 and 74 and either or both of the lengths of the respective acoustic ports 70 and 72 in the interior 18 of the guitar 10, Can be tuned separately to any desired frequency range proportional to the resonant frequency of the guitar. The optimal condition is that the acoustic ports 70 and 72 have rounded openings 73 and 74 of the same size in the respective members 77 and 78, Corresponds to 20% to 80% of the distance from the front acoustic board 12 to the rear acoustic board 14 in order to improve the tuning of the guitar. However, the lengths and size dimensions of the respective members 77, 78 of the respective acoustic ports 70, 72 need not be the same.

Each acoustic port 70,72 should preferably carry a panel 80,82 which is a geometrically straight panel connected between the front acoustic board 12 and the rear acoustic board 14, Is arranged between the acoustic ports 70 and 72 and the acoustic hole 13 and extends from a position relatively close to the lower bout of the guitar 10 to a position adjacent to the neck 17 of the guitar 10, The straight panels 80 and 82 are arranged so as to intersect each other near the neck portion 17 of the guitar 10. [ This will allow the sound to be funneled or vented towards the acoustic ports 70, 72. Although only two panels 80 and 82 are shown, additional linear panels can be used to form acoustic mazes within the interior 18 of the guitar body 11. [

An alternative to the use of straight panels 80 and 82 is shown in Figure 9a where each panel has a serpentine curvature in the form of "S " connected between the front acoustic board 12 and the rear acoustic board 14 Respectively.

As described above, panels 80, 82 are connected between the front acoustic board 12 and the rear acoustic board 14 because the panels 80, 82 are connected between the use of the support posts 23, Will serve as a structural support for preventing the front and / or rear acoustic board from collapsing when the tension is too high, either together or without it.
