  • Patent number: 8759648
    Abstract: The present invention is a banjo tone ring with vertical sides (30) as opposed to the angled design of conventional banjo tone rings (120). The ring (30) of the present invention has specific height (h) to width (w) or thickness ratios and is within specific weight ranges for improved performance It vibrates much freer and thus raises the quality of musical tones from the banjo (10) to much higher aesthetic levels. Other embodiments also modify the musical tones for different sounds. Several novel embodiments of manufacturing methods are also described.

  • Patent number: 8217254
    Abstract: In an implementation of this invention, a stringed musical instrument has a resonator comprised of a bridge and a soundboard. Vibrations from the strings are transmitted through the bridge to the soundboard. A plurality of sensors are attached to or embedded in the soundboard. The sensors measure primarily the vibrations of the soundboard, rather than primarily the vibrations of the strings. Preferably, three or more sensors are used. Piezoelectric sensors sample vibrations in the soundboard. The resonator includes a printed circuit board that amplifies the signal from each sensor separately. Also, a signal processing device that is “onboard” the musical instrument processes the separate input signals to create one output signal. The resonator may be easily removed, enabling resonators to be interchanged. Also, the physical characteristics of a particular resonator, such as its mass or its boundary condition, may be adjusted, thereby changing the acoustic qualities of the soundboard.

  • Patent number: 7687695
    Abstract: A method of assembling an anti-wolf resonator assembly for use with a string instrument is provided. The method includes positioning a first portion of the resonator assembly against a first side of a surface of the instrument, and magnetically coupling a second portion of the resonator assembly to a second side of the instrument surface that is opposite the first side of the surface. The surface is positioned between the first and second portions of the resonator assembly. The resonator assembly is configured to dampen at least one of a musical note and a vibration produced by the string instrument.

  • Patent number: 7498496
    Abstract: “Mitchel's Tone Ring Mate” is completely new to the banjo world. The “Mitchel's Tone Ring Mate” is a smaller tone ring in itself, sitting on top of the original raised head tone ring at 25 thousands higher and at opposite angles, thus converting the original raised head tone ring to a flat head tone ring. Being completely different than any other invention. This doing, by design, composition and development, unknown in manufacturing there into.

  • Patent number: 7476789
    Abstract: A device and method is disclosed for creating a customized chinrest for a violin or a viola, molded to conform to the precise idiosyncrasies of a player's chin and jaw, rendering greater comfort, support, range of motion, and control to the player. The chinrest of this invention is comprised of a rigid, flat, edgeless base upon which a removable, firm, but flexible silicone, custom molded top is adhered. The method of impression taking records complex contours, angles, and a range of motion created by head pivot of the player's chin and jaw while in the act of playing.

  • Patent number: 7259308
    Abstract: A resonator assembly includes a resonator, a collector-amplifier, as well as a timbre tray, one or more timbre pieces, and a detector holder. The resonator assembly, designed to be attachable to a conventional acoustic guitar, improves the quality and volume of the conventional guitar. A wood or metal timbre piece or a varying combination thereof may be used according the user's sound preference. The resonator, the collector-amplifier, the timbre holder tray and the detector holder are preferably made from thin brass.

  • Patent number: 6894209
    Abstract: A guitar configuration that has improved playability without requiring a raised fret or fingerboards or a neck that extends through the resonance chamber all the way to the sound hole is disclosed. The particular construction of the present invention includes a soundboard with a partially curved portion that provides additional clearance for the guitarist's hand thereby allowing the guitarist to play the higher fret positions without changing the position of the fretting hand. The tapered construction of the soundboard is achieved while maintaining the structural integrity of the guitar construction while eliminating the need for extending the neck of the guitar through the sound chamber up to the sound hole in the sounding board.

  • Patent number: 6800797
    Abstract: An electric guitar includes a hollow acoustic body, a plurality of strings, a fingerboard, air in the hollow acoustic body, and at least one speaker mounted in the hollow acoustic body. A sound system operatively associated with the strings and speaker causes sound to emanate from the speaker when the strings are played and causes sound to vibrate and resonate the hollow body and air in the hollow acoustic body.

  • Patent number: 6777603
    Abstract: The creation of sounds by musical instruments or sound reproduction systems is not perfect, but acoustic dissonances inherent in the production of sound generators can be corrected. The present method uses open volumes, such as a glass, possibly provided with a cutoff, a fragmentation creating at least one opening. This object placed close to or on a sound generator frees additional sound waves to harmonise with the sound generator by means of mechanical coupling or an air sound link due to the volume of the resonator and its fragmentation. A device made of a material with a Shore hardness of more than 60 makes it possible via its foot fixed to a piano to transmit mechanical sound vibrations. Method and device constitute an effective improvement in the reproduction and creation of sounds.

  • Patent number: 6563033
    Abstract: A stringed instrument such as a guitar with a thinner than traditional body is provided enhanced decibels measured by sound pressure level (DBSPL) response employing a combination of one or more of each of a passive radiator, tuned isolated resonating wave guide or guides in the body cavity and an equalized closeable sound opening in the front face configured to maximize volume at low frequencies and increasing low frequency response, e.g., at or less than 500 Hz. The passive radiator may be in either the front or rear or both faces. The wave guides each comprise elongated sheets in the body chamber spaced from the corresponding face by spaced posts. The wave guides may be in opposing cooperating pairs or may be staggered for directing low frequency waves to a sound opening in the front face and resonate to provide enhanced low frequency response and subsequent volume. The passive radiator in the rear face is recessed within the body chamber.

  • Patent number: 5355756
    Abstract: A banjo has a resonator (24) mounted about the pot (11) and acoustical links (25) that acoustically couple the resonator with the banjo head (14). When the instrument is played acoustical waves pass from the head through the acoustical links to the resonator which amplifies the sound produced by the banjo. An adoption of this invention is also disclosed for a guitar.
