METHOD FOR IMPROVING THE ACOUSTIC PROPERTIES OF SPRUCE RESONANCE WOOD

In a method for improving the acoustic properties of spruce resonance wood for musical instruments at least one resonance wood blank is subjected to a treatment with Physisporinus vitreus under controlled, sterile conditions. The previously sterilized resonance wood blank is immersed into a liquid medium enriched with fungus myecelium and kept therein in the dark for an exposure time and finally sterilized, wherein during the exposure time a temperature of 18 to 26 C. and a relative humidity of approximately 60 to approximately 80% are maintained. Due to the fact that the liquid medium contains nanofibrillated cellulose (NFC) in an amount of 200 to 300 g per liter, a reproducible, uniform improvement of the acoustic properties of the resonance wood free from local defects is ensured.

String tensioner for stringed instrument
10224009 · 2019-03-05 ·

A string tensioner module for a stringed musical instrument is configured to apply a constant or near-constant tension to the musical strings of the instrument. The module is divided into a plurality of string tensioners, one string tensioner for each musical string. Each string tensioner employs a primary spring that apply the primary force coaxial with the string. Each string tensioner also employs a secondary spring that applies a secondary force in a direction crossing the axis of the string, and thus applying an axial force component that changes as the angle of the secondary spring changes. The primary and secondary springs are selected so that the change in the axial force component of the secondary spring as the string changes in length approximates the change in force applied by the primary spring so that the axial force applied to the string remains generally constant even as the string changes in length.

Soundboard apparatus and method of forming
10204601 · 2019-02-12 · ·

The present invention concerns soundboard apparatus for a musical instrument, the apparatus comprising a soundboard substrate formed of composite fibrous resin bonded material having a thickness of between 0.75 mm and 3 mm; and an outer layer formed of ultra-violet light blocking material having a thickness of between 0.5 and 0.9 mm. Further, the present invention relates to a method of forming a soundboard apparatus, the method comprising the steps of: bonding multiple layers of woven or straight stranded fibrous material in a resinous matrix to form a soundboard substrate, wherein the soundboard substrate is formed such that it is oversized with respect to final soundboard substrate dimensions; and finishing the soundboard substrate to form the final substrate, the finishing process being constrained to ensure that the final substrate dimensions are not compromised.

Acoustic material and musical instrument

An acoustic material is provided which includes a plurality of wood veneers laminated via an adhesive, in which the veneer is impregnated with the adhesive, and the adjacent veneers are substantially in contact with one another. The adjacent veneers are impregnated with the adhesive in an amount of preferably no less than 1 g/m.sup.2 and no greater than 50 g/m.sup.2 per unit area in and around a boundary region of the adjacent veneers. The adhesive may be a water-soluble adhesive or a water-based emulsion adhesive. The veneer may be a rotary veneer, a sawn veneer or a sliced veneer. A musical instrument is further provided which includes a sound board, in which the acoustic material is used as the sound board.

Method and apparatus for waking-up violin and other string instruments
10121457 · 2018-11-06 · ·

Waking-up a violin or other instrument by determining naturally resonating features of a particular instrument by applying tones and analyzing the instrument's responses, and then applying vibrations (e.g., continuously and/or in patterns, such as alternating on/off, staccato, etc.) corresponding to the most responsive (resonant) portions of the instrument's responses (e.g., peaks of the analyzed instrument's response) fully breaking in the various parts of the instrument. The applied vibrations are continued until the instrument's amplitude response plateaus.
