Definitions

  • the present invention is directed to a stringed musical instrument such as a guitar, violin or banjo having a hollow or semi-hollow body for producing and controlling sound from two separate sound boards disposed on opposite sides of the musical instrument using only a single set of strings interconnecting a bridge on each sound board through the hollow interior of the musical instrument and a method of constructing a stringed musical instrument having a hollow or semi-hollow body for producing and controlling sound from each of two sound boards disposed on opposite sides of the body of the musical instrument using a single set of strings interconnecting a bridge on each sound board through the hollow interior of the musical instrument.
  • Conventional stringed musical instruments which have a hollow or semi-hollow body generate musical tones by strumming or plucking strings stretched over a bridge and saddle mounted on the sound board corresponding to the anatomical front of the musical instrument. Sound is produced by the vibration of the strings and transmitted from a bridge assembly, mounted upon the sound board, throughout the body of the musical instrument and exits through a sound hole in the musical instrument, generally located in the anatomical front sound board and usually underneath the strings.
  • the hollow interior of the body forms an acoustical resonant enclosure which enhances and amplifies the sound generated from the sound board.
  • the sound board of the musical instrument is conventionally understood to represent the top or front of the instrument.
  • the rear or back of the guitar is not considered to have much, if any, significance relative to the overall sound generated by the musical instrument and, as such, little attention is given to the wood used in the construction of the rear board of the guitar.
  • the front and rear boards are connected to the body of the instrument along the sides thereof to fully enclose the body surrounding the hollow interior.
  • the front board is recognized as the sound board of an acoustical guitar and is composed of expensive tone woods such as, for example, spruce and/or red cedar whereas the rear board is typically composed of inexpensive wood or other material.
  • the front and rear boards of a conventional acoustical guitar usually includes ribs on the inner side of each board facing the interior of the guitar to add to the structural strength of each board respectively.
  • no structural support exists between the front and rear boards of a conventional acoustical guitar other than the support provided by the sides connecting the front to the rear board.
  • the sound produced from a stringed musical instrument can be enhanced by simultaneously utilizing both sound boards inclusive of both the front sound board and the rear sound board of the guitar for generating sound independent of one another utilizing a single set of guitar strings to interconnect the front sound board to the rear sound board through the interior of the guitar.
  • This is accomplished in accordance with the present invention using a dual bridge and saddle assembly which includes a first bridge and saddle mounted on the front sound board of the musical instrument and a second bridge and saddle mounted on the rear sound board with a single set of guitar strings interconnecting the first bridge and the second bridge through the hollow interior of the guitar.
  • the dual bridge and saddle assembly should preferably also include support posts connected between the first bridge and the second bridge through the interior of the guitar for providing additional structural support for the guitar between the front sound board and the rear sound board respectively and provide support due to any compromise of support from the presence of the dual bridge
  • each sound board By vibrating the common set of strings extending between the two sound boards, sound is transmitted from both the front and rear sound boards of the musical instrument throughout the musical instrument interior to generate a composite of acoustical sound having an intensity and frequency range greater than the intensity and frequency range otherwise generated from an acoustical guitar with the guitar strings connected only to the front sound board. Moreover, sound is further enhanced by coupling each sound board to its own separate sound (pre)amplifier and/or amplifier, which enables the sound produced from each sound board to be independently and separately controlled.
  • pre separate sound
  • At least one of the sound boards include at least one sound port, in addition to the conventional sound hole, through which sound can exit from the guitar independent of the sound hole.
  • the sound port may be located in the general vicinity of the sound hole and should comprise a hollow member of any desired geometry, preferably a tube adapted to be inserted through an opening formed in one of the sound boards, preferably the front sound board, with the hollow member having a length extending from the front sound board to a location within the hollow body of the instrument equal to 5% to 95% of the distance between the front sound board and the rear sound board and forming an opening through the front sound board of any desired size dimension preferably a round in geometry.
  • the sound port By varying the extended length of the sound port within the interior of the guitar i.e., selecting a desired length from various different lengths each within the desired range depending on the sound intended the sound port can be tuned to different desired frequency ranges proportional to the resonant frequency of the guitar, e.g. to possess a higher and/or lower frequency spectrum corresponding to a treble or bass sound range different from the frequency spectrum of the sound exiting the sound hole thereby creating a greater dynamic frequency range produced by the musical instrument.
  • the panel(s) should be arranged to lie between each sound port and the sound hole, generally but not limited to the upper bout of the guitar and extend preferably up to the neck of the guitar or may interconnect with another panel near the neck of the guitar. In this arrangement, the panels cause sound to be directionally funneled to each sound port and thereby exit the sound port(s) in addition to sound exiting the sound hole.
  • the panel(s) Since the panel(s) are connected between the front and rear sound boards, the panel(s) will inherently provide structural support between the front and rear boards of the guitar serving as an alternative to the current standards and use of ribs on the front and/or rear sound boards in addition to support provided by use of the support posts in the dual bridge and saddle assembly.
  • the stringed musical instrument of the present invention comprises a body having a first sound board representing the front surface thereof, a second sound board representing the rear surface thereof, a common hollow or semi-hollow interior extending between the first sound board and the second sound board, and a dual bridge and saddle assembly extending between the first sound board and the second sound board with the dual bridge and saddle assembly comprising a first bridge and saddle mounted upon the first sound board, a second bridge and saddle mounted upon the second sound board and a single set of strings interconnecting the first bridge and the second bridge of the dual bridge and saddle assembly through the common interior of the musical instrument.
  • the present invention also broadly encompasses a method of constructing a stringed musical instrument, having a body with a hollow or semi-hollow interior, a front and rear sound board disposed on opposite sides of the interior, a single set of strings and a dual bridge and saddle assembly including a first bridge and saddle for the front sound board and a second bridge and saddle for the rear sound board comprising the steps of mounting the first bridge in the dual bridge and saddle assembly upon the front sound board, mounting the second bridge in the dual bridge and saddle assembly upon the rear sound board, and stringing said single set of strings to the musical instrument such that the strings extend between the first bridge and the second bridge through the interior body of the musical instrument for generating sound from each sound board respectively.
  • the method further includes structurally connecting the first bridge to the second bridge in the dual bridge and saddle assembly using support posts for providing structural support between the front and rear sound boards respectively.
  • the musical instrument of the present invention is illustrated by an acoustical guitar 10 as shown in figures 1-9 inclusive, representing the preferred embodiment thereof.
  • the acoustical guitar 10 comprises a body 11 which includes a front sound board 12 as shown in figure 1 , a rear sound board 14 as shown in figure 2 and a dual bridge and saddle assembly 16 as more specifically shown in figures 8A , 8B , 9A , 9B and 12 respectively, which extends through the hollow or semi-hollow interior 18 of the body 11 from the front sound board 12 to the rear sound board 14 of the guitar 10.
  • the guitar 10 has sides 13, as shown in figures 3, 4 and 6 , connecting the front sound board 12 to the rear sound board 14 to fully enclose the body of the guitar 10.
  • the dual bridge and saddle assembly 16 shown in figure 8A extending between the front and rear sounds boards 12 and 14, comprises a first bridge 20 mounted upon the front sound board 12, a second bridge 22 mounted upon the rear sound board 14, support posts 23 and 24 which interconnect the first bridge 20 to the second bridge 22, a saddle assembly 30, adapted for insertion within a slot 34 in the first bridge 20 as shown in figure 9B and a saddle assembly 31 adapted for insertion within a slot 40 the second bridge 22.
  • a single set of strings 33 extend from the headstock 19, which represents the top end of the guitar 10, along the neck 17 of the guitar 10 to the first bridge 20, mounted upon the front sound board 12, and from the first bridge 20 to the second bridge 22, mounted on the rear sound board 14, through the hollow interior 18 within the body 11 of the guitar 10.
  • One end of each string in the set of guitar strings 33 is connected to tuning knobs 15 in the headstock 19 and the opposite end of each string in the set of strings 33 is pegged to the second bridge 22 so that the set of strings 33 interconnect the first bridge 20 to the second bridge 22 through the interior 18 of the guitar 10.
  • the set of strings 33 are preferably strung starting from the pegged location in the second bridge 22 on the rear sound board 14 over a saddle 48 inserted into the second bridge 22 to the first bridge 20 over a saddle 44 into the first bridge 20 from whence the set of strings 33 continue along the neck 17 of the guitar 10 to the tuning knobs 15 as will be further described in connection with figures 9B and 12
  • the support posts 23 and 24 in the dual bridge and saddle assembly 16 function to support and secure the upper sound board 12 in the guitar 10 to the rear sound board 14 so that neither the front and/or rear sound boards 12 and 14 collapse from too much tension in stringing the guitar strings 33.
  • the use of the support posts 23 and 24 is preferred but is not critical to the invention since structural support to prevent collapse of either the front or rear board 12 and 14 relative to one another is obtainable using other support members between the front sound board 12 and the rear sound board 14 independent of the support posts 23 and 24 in the dual bridge and saddle assembly 16 as, for example, will become apparent later in the description in connection with the incorporation of panels 80 and 82 in conjunction with the use of sound ports 70 and 72, respectively.
  • the support posts 23 and 24 in the dual bridge and saddle assembly 16 are preferably disposed at an inclined angle between the front sound board 12 and the rear sound board 14, as is shown in figure 8A , with the upper sound board 12 positioned slightly forward toward the neck 17 of the guitar 10 relative to the position of the rear sound board 14. This arrangement relieves some of the tension in the set of guitar strings 33 during tuning of the guitar 10.
  • the support posts 23 and 24 may be constructed of any desired material composition preferably a wood or wood substitute composition and may have any desired geometrical shape including, for example, a square, rectangular, or cylindrical shape.
  • the first bridge 20, in the dual bridge and saddle assembly 16 as shown in figures 1 and 9B comprises a slot 34 into which the saddle assembly 30 is inserted and includes a plurality of openings 35 through which the guitar strings 33 are strung with the number of openings 35 corresponding to the number of guitar strings 33 such that for example, if the guitar 10 has six guitar strings 33 the first bridge 20 will have six openings 35.
  • the openings 35 in the first bridge 20 are aligned in a substantially horizontal plane transverse to the direction of the set of guitar strings 33.
  • the slot 34 in the first bridge 20 may preferably lie at an acute angle relative to the horizontal, as is shown in figure 1 , to facilitate and/or permit adjustment of the specific intonation of the guitar.
  • the first bridge 20 may conform in geometry and dimension to the geometry and dimension of the second bridge 22 in the dual bridge and saddle assembly 16, except for its width dimension.
  • the second bridge 22 should preferably have a width "d", as shown in figure 2 , which is wider than the width of the first bridge 20 to accommodate two sets of openings 38 and 39 for the guitar strings 33 as opposed to only one set of openings 35 in the first bridge 20.
  • the set of openings 39 in the second bridge 22 are used to secure and peg one end of each of the guitar strings 33 into the openings 39.
  • the two sets of openings 38 and 39 should be arranged in parallel to each other on opposite sides of the slot 40 in the second bridge 22 and should include a total number of openings corresponding to twice the number of string openings 35 present in the first bridge 20.
  • the strings 33 are pegged to the openings 39 in the second bridge 22 using peg members 42 as is shown in figures 9B and 12 which are inserted into the openings 39 in engagement with one end of each string 33 so that each peg member 42 engages each string 33 in each of the openings 39 to firmly secure the engaged end of each string into one of the openings 39.
  • the guitar strings 33 are then strung over the saddle 48 in the saddle assembly 31 as shown in figures 9B and 12 from the pegged ends in the openings 39 through the corresponding set of openings 38 in the second bridge 22 and then through the openings 35 in the first bridge 20 from whence they are strung over the saddle 44 in the saddle assembly 30 and along the neck 17 of the guitar 10 to the tuning knobs 15 at the front end 19 of the guitar 10.
  • the saddle assembly 30, which is insertable into the slot 34 in the first bridge 20 of the dual bridge and saddle assembly 16, includes the saddle 44, a pickup device 45, a wire cord 46 and an output jack 47 as shown in figure 9B .
  • the pickup device 45 is a conventional component comprising a sound pickup type such as a piezoelectric shielded magnetic device in a coil of wire.
  • the jack 47 extending from the wire cord 46 is adapted for attaching the pickup device 45 to a preamp 60 mounted on a side 13 of the guitar 10 as shown in figure 7 .
  • the saddle assembly 31, which is insertable into the slot 40 in the second bridge 22 of the dual bridge and saddle assembly 16 comprises a saddle 48, a pickup device 50, a wire cord 51 and an outlet jack 52 which extends from the wire cord 51 for attaching the pickup device 50 to a separate preamp 62 which may also be mounted on the same side 13 of the guitar 10.

  • Each saddle assembly 30 and 31 includes a saddle 44 and 48 and a pickup device 45 and 50 respectively.
  • the saddles 44 and 48 function to support the set of guitar strings 33 over the first and second bridges 20 and 22 on the front and rear sound boards 12 and 14 respectively.
  • Each saddle 44 and 48 may be a component of the saddle assembly 30 and 31 separate and independent of each pickup device 45 and 50 or alternatively one or both of the saddle assemblies 30 and 31 may have the pickup devices 45 and 50 integrated into the saddle assembly 30 and 31 to form a single integrated unit which incorporates both a saddle and pickup in combination.
  • the pickup device 50 in the saddle assembly 31 is adapted to be inserted into an opening 57 formed in the saddle 48 thereby forming an integrated unit whereas the pickup device 45 in the saddle assembly 30 may or may not be integrated into the saddle 44 to form a single unit.
  • the pickup device 45 in the saddle assembly 30 represents an independent component and, as such, must be separately inserted into the slot 34 in the first bridge 20 followed by insertion of the saddle 44 into slot 34 over the pickup device 45 whereas the saddle 48 combined with the pickup device 50 is inserted as one integrated unit into the slot 40 in the second bridge 22.
  • the saddle component 44 and 48 in each of the saddle assemblies 30 and 31 should have a configuration which includes a body portion 53, 55 and a thin section 54 extending outwardly from the body portion 53, 55.
  • the thin extended section 54 should be substantially of rectangular geometry so that each saddle 44 and 48 forms, in cross section, a "T" configuration with the extended thin section 54 representing the vertical side of each "T" configuration and the body portion 53,55 representing the horizontal side.
  • the thin section 54 extending from each saddle 44 and 48 should have a width conforming to the width of the slots 34 and 40 in the first and second bridges 20 and 22 respectively, and should have a width substantially thinner than the width of the body portion 53, 55 from which it extends.
