摘要： This invention is an apparatus for straightening a guitar bridge or guitar bridge assembly comprising a U-shaped receptacle with a bottom, a first face and a second face; an adjustable drive on the first face that places force on the bridge; and at least two opposing braces on the second face, and wherein the second face is grooved to create a space between the receptacle and the bridge, and wherein the first and second face contain a sight line and the apparatus contains an adjustable drive which is capable of being turned by a hex wrench so that the force of the adjustable drive on one side and the two opposing braces change the shape of the bridge to a desired shape. The invention is also related to a method for straightening a guitar bridge.

摘要： A pitch changer system for a string musical instrument, including a lever assembly, a rotating saddle assembly, a swing plate, and a lever tensioning assembly. Applying force to move the lever in a first direction forces a bell crank matingly coupled to the lever into rotation such that a coupling system of the lever tensioning assembly causes the swing plate to force a rotating saddle of the rotating saddle assembly into rotation to elongate and thereby temporarily change the pitch of a string coupled to the rotating saddle.

摘要： A stringed instrument, such as a semi-acoustic electric guitar, can employ a resonance system that consists of a body having at least one internal cavity accessed by a soundhole continuously extending from a top cover. The soundhole may have a continuously curvilinear transition from the top cover and a length corresponding with an altered resonance frequency of the instrument body.

摘要： A sound processing component applied to a string instrument for providing multiple playing forms and a MIDI function. An acquisition module acquires vibration information of multiple strings and outputs analog signals, and a first amplification and filter module amplifies the analog signals and filters the analog signals. A first conversion module converts the analog signals into digital signals, and a processing module identifies playing information of the digital signals, converts the digital signals to MIDI data based on the playing information, converts the MIDI data to audio data, and add audio effects for the audio data. A second conversion module converts the audio data with the audio effects into analog audio signals, and a second amplification and filter module amplifies the analog audio signals, filters the analog audio signals, and transmit the filtered analog audio signals to a loudspeaker. The string instrument is also provided.

摘要： A string mount system and method of installing guitar strings in an acoustic guitar. The string mount system includes a tonebar having a rod including a length extending from a first terminating end to a second terminating end. The tonebar includes a constant diameter extending along the length of the rod and the constant diameter is less than an inner diameter ball end of each string in a set guitar strings. The rod is located in a hole in each of the ball ends. The tonebar, with the mounted strings, is pulled against a bridge plate of the guitar. The strings are tuned to pitch. The strings are acoustically coupled to the bridge plate and to the sound board to vibrate the soundboard to produce acoustically amplified string tones.

摘要： A hybrid-material construction for string instruments may include providing an internal lattice framework structure encased in a composite material to produce a final form of a string instrument. The framework structure may provide a lightweight structural support system within a finished instrument to reduce overall weight while maintaining strength of the instrument.

摘要： Disclosed is an improved vibrato device. The typical components of the disclosed device include, but are not limited to, a dual spring-loaded lever arm 10. The lever arm 10 is intended to sit separate and away from the instrument's strings 70 to allow for the user to manipulate the instrument's vibrato while playing by manually moving the lever arm 10 closer to or farther from the instrument. The lever arm 10 connects to the dual spring system 15; the dual spring system 15 houses the vibrato device's springs that allow vibrato manipulation and sits attached to the tremolo system's tailpiece 60, which anchors the vibrato device to the instrument, and the pivoting metal bar 40. The pivoting metal bar 40 is the strings' 70 anchor-point at the base of the instrument, and the bar 40 pivots in response to the lever arm 10 being raised or lowered. When the bar 40 pivots, it either lessens the strings' 70 tension when the lever arm 10 is lowered or increases the strings' 70 tension when the lever arm 10 is raised.

摘要： A stringed instrument bridge comprising: a bridge body; a receiving surface located on the bridge body; a first angled member abutting a first side of the receiving surface, the first angled member having a first angled surface with a first threaded hole; a second angled member abutting a second side of the receiving surface, the second side on an opposite side from the first side, the second angled member having a second angled surface with a second threaded hole; a plurality of saddles, each saddle configured to sit the receiving surface; a first wedge lock, the first wedge lock having a first slotted screw hole, the first wedge lock configured to attach to the bridge body at the first angled member via a first screw configured to engage the first slotted screw hole and the first threaded hole; a second wedge lock, the second wedge lock having a second slotted screw hole, the second wedge lock configured to attach to the bridge body at the second angled member via a second screw configured to engage the second slotted screw hole and the second threaded hole; where when the first and second wedge locks are loosely attached to the first and second angle members, the saddles may be adjusted into an adjusted position with respect to the receiving surface; and where when first screw is tightened and the second screw is tightened, the first and second wedge locks fixedly hold the saddles in the adjusted position. The invention also relates to a saddle for a stringed instrument bridge, the saddle comprising: a first threaded hole extending from the bottom side to the top curved surface on the first side of the peak; a second threaded hole extending from the bottom side to the top curved surface on the second side of the peak; the first threaded hole and the second threaded hole are both offset from the longitudinal centerplane and configured to allow tool clearance from and instrument string; and an unthreaded through hole from the first vertical planar surface to the second vertical planar surface, the unthreaded through hole having a domed shape; a retention wire threaded hole extending from the bottom side up into the bottom surface of the unthreaded through hole; a retention wire set screw configured to screw into the retention wire threaded hole and further configured to impinge a retention wire against the top surface of the unthreaded through hole; and the domed shape configured to center a retention wire over a retention wire set screw.
