摘要： The invention relates to a device for tightening the strings of a keyboard musical instrument. The device provides for rigidly securing a tuning pin in position by means of a collet pressing into a cast-iron frame, an elastic ring being mounted on windings of a string. The present technical improvements increase tuning stability and tuning retention, increase string resistance to breaking, and increase the service life of a musical instrument.

摘要： A keyboard device where at least one of a transmission rail and a hammer rail is favorably supported, and a keyboard instrument including the keyboard device are provided. A transmission support pole for supporting the transmission rail and a hammer support pole for supporting the hammer rail are each arranged in a gap between two keys adjacent to each other among a plurality of keys, arranged in a hole provided in at least one of the plurality of keys, or arranged at a position corresponding to a key support shaft which supports at least one of the plurality of keys. As a result, at least one of the transmission support rail and the hammer support rail is favorably supported.

摘要： A stroke adjustment device for a keyboard instrument, which can finely adjust key depression stroke and hammer stroke to obtain sufficient controllability of weak tones during musical performance and make the dynamic range even wider. This device includes a lifting mechanism for lifting up and down a keyboard pillow on which rear ends of keys are placed, an operation mechanism manually operated for driving the lifting mechanism, and a driving force transmission mechanism for transmitting a driving force generated by operation of the operation mechanism to the lifting mechanism. The lifting mechanism has a rotating shaft body rotatably provided below the keyboard pillow, vertically movable rack parts in mesh with gear portions that rotate in unison with the rotating shaft, and a lifting part extending over the rack parts and vertically moving in unison with the rack parts to lift up and down the keyboard pillow.

摘要： A toy piano including one or both an enlarged sound plate intermediate the sound bar of the toy piano and its sound board, and a sound box into which the sound board is incorporated. Preferably, the sound plate extends beyond the normal edges of the sound bar in which the longitudinal tines of the toy piano are mounted so as to lie adjacent to the sound board over a larger area. Likewise, the sound box should preferably be shaped so as to be somewhat wider (measured in the longitudinal direction of the tines) towards the end where the tines are longest (and produce lower tones) and somewhat narrower towards the end where the shorter tines (producing higher tones) are located. It preferred shape is characterized, by somewhat convex curves at the more treble and bass ends, respectively, of the sound box with a somewhat concave curve intermediate these two ends. The backboard of the sound box can be bowed outward for enhance acoustics.

摘要： 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.

摘要： A piano (1) having a dense sound-enhancing component (2), said piano (1) having a case (6), a frame (3) located within the case (6), strings (5) located within the frame (3), keys (9) in connection with hammers (11), two bridges (13) each of stone having a top face (27), a bottom face (28), a first side (29) and a second side (30), bridge pins (16) extending from the top face (27) at an angle, the strings (5) extending across the bridges (13) adjacent to the bridge pins (16), a soundboard (4) and an amount of epoxy (18) located between the bridges (13) and soundboard (4). The dense sound-enhancing component (2) is a stone material, preferably granite, and enhances the sound of the piano (1) by holding and sustaining pitch longer, providing a longer and stronger signal, providing a higher volume or decibel level and having a decreased decibel fall-off as compared to conventional pianos utilizing wood bridge(s).
