摘要： The invention is a micro-tuning device for pianos and other keyboard-operated stringed musical instruments. A mass is secured to a single string or choir of strings in the musical instrument by an attachment device between the bridge and the agraffe, nut or V-bar, thereby reducing the speaking length and increasing the pitch of the string.

摘要： A present disclosure relates to a method and apparatus for tuning piano strings by heating the piano strings. The apparatus includes split magnetic cores that encircle the piano strings. The magnetic cores comprise wiring wrapped around the outside of the magnetic cores to induce an alternating current in the piano strings through mutual inductance. The generated alternating current in the piano strings allows each piano string to be heated and thereby tuned.

摘要： Important new descriptors (Down Force Slope and Up Force Slope), which more fully and meaningfully characterize the continuous Down Force and Up Force are revealed. Similar descriptors are also created to more fully characterize the Balance Force and Frictional Force curves. The invention also discloses various methods and means for accurately testing, measuring and determining other parameters (including the position of the at-rest key, key sluggishness, and others characterizing the “let-off” event) in an accurate and efficient manner. Methods of quantifying and measuring the actual inertia of a key action—in a non-invasive manner—are also disclosed, with several inertial parameters being defined. Methods for quantifying and measuring the actual inertia of the major individual components of a key action are also detailed, along with parameters and methods for expressing their contribution “at the key”. All of the various measurement methods of the current invention are performed in a “controlled, kinetic and continuous” manner.

摘要： A wood member for a musical instrument, which is capable of preventing occurrence of damage, such as cracking, to thereby ensure smooth and stable operation of the musical instrument and maintain excellent appearance of the same over a long time period. The wood member has compressive internal stress remaining at least in an outer peripheral portion thereof by being subjected to heating processing, cooling processing, and moisture conditioning processing, in advance. A wood workpiece as a workpiece for the wood member is heated at a predetermined temperature, and the heated wood workpiece is cooled. The cooled wood workpiece is subjected to moisture conditioning such that compressive internal stress is generated at least in an outer peripheral portion of the wood workpiece.

摘要： New parameters (Down Force, Up Force, Balance Force, and Average Friction) are defined for evaluating important “stroke characteristics” of individual key actions of one or more pianos or keyboards, describing exactly how these parameters are to be tested, measured and determined. The new parameters are designed to replace the prior art parameters of Down Weight, Up Weight, Balance Weight and Friction. Various methods, means and apparatus are disclosed for accurately testing, measuring and determining these new parameters, with the capability of performing thousands of measurements—on thousands of different key mechanisms—in a short amount of time.

摘要： The invention relates to a method for improving the sound of acoustic musical instruments by decoupling the part of a musical instrument that is directly responsible for producing the primary sound event from the elements and components that are not directly involved in producing the primary sound event. The limitation of the acoustically active part prevents elements (6, 7) that have primarily static or optical functions or serve to produce variety of playing technique from vibrating or emitting sound, since they may lead to interferences and distortions of the primary sound event. According to the invention, an intermediate layer produced from a material (1) that reduces sound conduction is arranged in the connecting zones between the elements.

摘要： I have discovered a way to improve the sound of musical instruments that utilize a soundboard or sound generating surface such as found in stringed musical instruments. I accomplished this by establishing a pronounced textured acoustical diffusing surface to one or more of the overall surfaces of the vibrating sound generating surface or soundboard of a stringed musical instrument creating greater surface area from which to generate greater acoustic energy. The result-compared to existing methods of improving the performance of soundboards of stringed musical instruments-is improved volume, timbre, projection, and tonality and sustain of the acoustical sounds produced by the stringed musical instrument.

摘要： Composite or plastic molded articles used in a grand piano piano action. The articles make up a piano action with less dynamic mass which is, thus, more responsive to the piano player. In addition, the new action provides the extremely valuable collateral benefits of increased efficiency of manufacture and maintenance.

摘要： A universal grand piano piano action that has adjustable connections between the repetition base, heel, and rest cushion bracket of the piano action to provide a one-size-fits-all after-market replacement piano action for any grand piano. Other components of the grand piano piano action, such as the jack and flanges, may require specific design and manufacture for each brand of grand piano. This invention is the first piano action to allow for true simultaneous half stroke keyboard design for both the white and sharp keys of a piano and includes the method for installing such.
