| 20150047492 | PIANO OR GRAND PIANO WITH STRINGS AND A SOUND BRIDGE - The present invention relates to a piano or a grand piano with a resonance board and strings which rest on a sound bridge with two longitudinal faces. Such a sound bridge serves to transmit vibration energy which is output by the strings of the instrument to a resonance board. The invention is based on the realization that, on the one hand, the rigidity of the sound bridge must be maintained at the locations at which it is in contact with the strings and the resonance board. On the other hand, it is advantageous if the mass of the sound bridge is reduced. For this reason, according to the invention it is proposed that the sound bridge have a first cutout and a second cutout, wherein the two cutouts are arranged on the two longitudinal edges of the sound bridge which lie opposite one another. | 02-19-2015 |

| 20090277318 | Wrestplanks - A wrestplank for use in a stringed instrument including first and second median working plies stacked in between first and second outer working plies. Each working ply defines a direction of grain. The working plies collectively define a tuning pin hole configured to securely receive a tuning pin, whereby the tuning pin is substantially surrounded by and in engagement with end wood of the working plies. The directions of grain of the outer working plies are oriented substantially parallel with respect to a longitudinal axis defined by the wrestplank. The grain direction of the first median working ply is oriented at an angle of between about 60° and about 75° with respect to the longitudinal axis, and the grain direction of the second median working ply is oriented at an angle of between about 105° and about 120° with respect to the longitudinal axis. | 11-12-2009 |

| 20100050850 | METHOD FOR IMPROVING THE SOUND OF MUSICAL INSTRUMENTS - Disclosed is a method for improving the sound of acoustic musical instruments by suppressing energy storage effects resulting in undesired interferences and distorted sounds. This is done by specifically directing the sound energy (kinetic disposal) away from parts not directly required for generating sound before the sound energy can influence the desired, primary sound event of the musical instrument. In a second aspect, the lowest energy level for generating sound, and thus the optimal initial state of all instrument parts required for creating the primary sound event, is restored as quickly as possible by means of said kinetic disposal. The kinetic disposal is obtained by arranging at least one crystalline member ( | 03-04-2010 |
| 20110259169 | MOVABLE PART FIRMLY EQUIPPED WITH BALANCE WEIGHT, MUSICAL INSTRUMENT AND METHOD OF ASSEMBLING BALANCE WEIGHT THEREIN - Keys of a piano are depressed against the total weight of associated action units and hammers so that balance weight pieces are embedded in the front portion of each key; since the wood bar of the key is expandable and shrinkable due to the conditions of the environment, the weight pieces are liable to come loose; the balance weight piece is formed with ridges and valleys repeated at least 7 times at fine pitches equal to or less than 2 millimeters, and the maximum diameter of the ridges is slightly longer than an inner diameter of a hole formed in the wood bar; while the balance weight piece is being pressed into the hole, the ridges make the inner surface portion elastically deformed; when the balance weight piece reaches the target position, the inner surface portion penetrates into the valleys so that the balance weight piece is lodged therein. | 10-27-2011 |
| 20130061733 | KEYBOARD INSTRUMENT - In a predetermined sound generation mode, a drive signal having a frequency characteristic corresponding to an operated key is supplied to an excitation unit provided on a soundboard. In response to a mechanical vibration generated by the excitation unit, the soundboard is vibrated so as to generate an acoustic vibration sound corresponding to the operated key. The excitation unit is supported by a supporting unit such that less or no load of the excitation unit except a vibration member vibrated in response to the drive signal is applied to the soundboard. Thus, only a load of the vibration member which is a very light portion of the excitation unit is applied to the soundboard, thereby vibration characteristics of the soundboard being hardly affected. When a sound damping mode is selected, a stopper is permitted to prevent a hammer from striking a sounding body. | 03-14-2013 |
| 20140041505 | ATTACHABLE MUSIC BOOK HOLDER - An attachable book holder is disclosed for a piano having a music rest, where the music rest has upper and lower outer surfaces. The attachable book holder comprises an elongate finger element and an attachment means which is connected to the elongate finger element at a connection point. The attachment means is attachable to at least one of the outer surfaces of the music rest at one or more contact regions. The elongate finger element is adjustable between a first orientation in which the finger element extends upwards from the connection point and a second orientation. The attachable book holder can be used on modern pianos which are supplied without book holders as part of the music rest, or alternatively the attachable book holder can be used to replace faulty or missing book holders on older pianos. In the former case there is no need to drill the casing of the book rest to attach the book holder to the music rest. | 02-13-2014 |
