  • Patent number: 7285708
    Abstract: A stringed musical instrument having an elongate neck and a body which may have a resonant cavity at one end and a head at the other end thereof. Strings extend across the neck and, when vibrated, generate musical sounds. The invention relies upon fingerboards which are removable so that one type of fingerboard may be substitutable for another type of fingerboard in order to generate sounds of different timber or of different qualities. Thus, fretted fingerboards are substitutable for non-fretted fingerboards. Moreover, and in a preferred embodiment, the fingerboards are inserted onto the neck of the instrument and can be slid into and out of interlocking elements from one longitudinal side of the neck of the instrument. In one embodiment of the invention, dovetail projections are formed on the neck of the musical instrument and corresponding notches or grooves are formed on the underside of the fingerboard to permit an interlocking arrangement of the fingerboard on the neck of the musical instrument.

  • Patent number: 7157633
    Abstract: A simulated stringed musical instrument practice device having integrally formed longitudinal ridges simulating strings is herein disclosed. The present invention generally comprises an elongated section of material that is similar in shape to the neck of a conventional stringed instrument. The elongated section has a flat surface fashioned thereon having transverse ridges simulating frets as well as longitudinal ridges integrally attached thereto simulating strings. The frets are spaced progressively longer distances apart in order to more accurately simulate the fret board of a conventional stringed instrument. Optionally, the present invention may also provide utility as a computer keyboard wrist rest. Non-slip footings are provided for attachment to the flat surface in order to provide for secure placement adjacent the keyboard of a computer in a manner similar to conventional wrist rests.

  • Patent number: 6772856
    Abstract: The fine jet control type sound absorption system of this invention, aimed at absorbing low-frequency sound with both discrete frequency and broadband frequency to the same degree as already existing acoustic lining can do, is composed of two parts. One is a barrier wall covering an air space in which the concerning low-frequency sound propagates and having a multiplicity of small holes formed therein. The other is the means for causing a fine jet passing through these small holes into or out from the air space. This sound absorption system realizes a fine jet in the vicinity of the barrier wall for the purpose of canceling the sound inside the air space by means of the interference of the sound with the fine jets. Any of or a combination of shape of small holes, jet ejection angle or suction angle, amount of jet flow, thickness of a barrier wall back layer and air flow angle at which secondary air flows into the barrier wall back layer is selected.

  • Patent number: 6774292
    Abstract: A stringed musical instrument, which has a neck assembly, a body, and a plurality of strings. The neck assembly having a structure made of wood and composite materials of graphite/carbon fiber, and epoxy resins. Which is of sufficient strength and stiffness to withstand, without deformation, the entire load imposed upon the neck assembly by the tension of the strings. The neck assembly will include one structural load bearing wooden core, laminated with the composite external skin structure and epoxy resins, and will extend completely along the length of the neck assembly. The use of wood as a core structural material will enable the instrument to retain the response and tonal qualities of stringed instruments, which is common to a traditional wooden neck assembly. A fingerboard of wood is bonded to the composite external structure and a non-structural, non-load bearing two way string orbit relief adjustment mechanism is installed in the node region along the longitudinal axis of said neck assembly.

  • Patent number: 6646190
    Abstract: A stringed instrument with a compliantly suspended sound board allows for deeper, richer sound in s smaller sized instrument. The compliant suspension of the sound board allows for greater acoustic excursions at the edges of the sound board. The resonance set up between the compliance of the sound suspension and the mass of the sound board may be placed below and near the Helmholtz resonance of the instrument to effectively create a broader, lower-frequency Helmholtz resonance than would typically be achievable in instruments of similar size.

  • Patent number: 6593516
    Abstract: A holder for a single musical instrument reed provides the proper pressures upon a reed being held therein, to assure that a moist reed will dry properly without warping after use. The present holder has a laterally bowed, outwardly convex first panel and an opposite flat second panel, with the reed fitting therebetween. A pair of longitudinal ribs extend along the inner surface of the first panel and bear against the curved surface of the reed stored therein, to hold the opposite flat surface of the reed securely against the flat inner surface of the second panel and assure that the reed cannot bend or warp within the holder. The holder is preferably formed of a polyethylene plastic material, which allows the sides to be flexed inwardly to bow the first panel away from the reed, thereby allowing the reed to be withdrawn from the holder.

  • Patent number: 6586664
    Abstract: A drum muting system is provided to be removably mounted on a drum which muffles the natural sound produced by the drum, thereby allowing the tone of the drum to be controlled. The drum muting system includes an outer frame, a muting element, an inner muting assembly, a drum mounting structure, and an adjustment mechanism. The outer frame supportably engages the inner muting assembly which includes the muting element and a muting element support member. The inner muting assembly is maintained in an operative position relative to the outer frame by a suspension assembly which includes at least one but preferably a plurality of biasing elements secured to the outer frame and inner muting assembly by biasing element anchors. The adjustment mechanism permits the muting element to be selectively positioned relative to the outer surface of the drum head to permit an increase or decrease in the muting effect achieved.

  • Patent number: 6581719
    Abstract: A loudspeaker system containing wave-shaping sound chambers with approximately rectangular inlets and outlets of substantially the same size that are used to flatten or control the curvature of the acoustic wavefronts contained within system waveguides. Control of the degree of curvature of the wavefront enables the development of a wide variety of multi-waveguide arrays. The sound chambers are placed between a waveguides and a flattened conical horns of secondary waveguides. The sound chambers transform the curvature of the typical fan shaped wavefront that results from a conical horn throat into a wavefront that approximates a planar or curved rectangular ribbon of sound.
