摘要： A sound producing apparatus includes: a plurality of sound producing members with differing oscillation frequencies; dampers each corresponding to a respective sound producing member and suppressing vibration by contacting the corresponding sound producing members; a damper operation mechanism that moves each damper, thereby controlling a state of contact of the damper with a corresponding sound producing members; a soundboard that undergoes sympathetic resonance with sound producing members; a vibrator that vibrates the soundboard; an acquisition unit configured to acquire an audio signal; a signal output unit configured to: generate a drive signal for driving the vibrator with a vibration corresponding to the acquired audio signal; and output the drive signal to the vibrator; and a damper control unit configured to drive the damper operation mechanism to change a state of contact between the sound producing members and their corresponding dampers, based on frequency distribution of acquired audio signal.

摘要： A damper lever for a grand piano is provided for realizing a significantly cost reduction, a higher dimensional accuracy at a fabricating stage and a higher weathering resistance, and for permitting lead pieces to be stably fixed in a lever body without causing fracture or deformation of the lever body. The damper lever for a grand piano is composed of a lever body formed of a molded plastic material, and having a fitting recess formed on one side surface thereof and an inserting hole extending from the fitting recess and open to the other side surface of the lever body, and a plurality of lead pieces each having a head and a shaft extending from the head. Each lead piece has its head inserted into the inserting hole of the lever body and the head fitted in the fitting recess of the lever body, and a top end of the shaft is caulked to fix each lead piece in the lever body.

摘要： A grand piano soundboard with a bar and sound tunnels has an outer wall with first and second grooves. The first groove is arranged diagonally in the width direction. The second groove is arranged diagonally in the length direction. The grooves cross and connect on the outer wall of the soundboard. The outer wall is divided into four resonance regions, and its center has a bar assembly having strip-shaped bar members arranged on both sides of the grooves in pairs; The grooves form a sound tunnel on the outer wall. The soundboard is changed from the previous free vibration mode to the current standard vibration mode. The treble of the grand piano is bright and the bass was sonorous and mellow from the perspectives of vibration, resonance and phonation. The design scheme has outstanding substantive characteristics and remarkable technical progress, and has obtained technical results.

摘要： 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.

摘要： The Invention relates to a keyboard instrument with a keyboard and a sound board including a front edge which runs substantially parallel to the keyboard. The sound board further includes a first lateral edge which forms a first angle (A) with the front edge, and a second lateral edge which forms a second angle (B) with the front edge. Strings are provided which are induced to vibrate by respective keys of the keyboard. There is also at least one sound bridge which is secured to the sound board and on which the other end of the strings which faces away from the keys is supported. The first angle (A) is >90°. The sound bridge extends at a right angle on the sound board approximately as far as a line that runs rearwards from the intersection of the front edge of the sound board and the first lateral edge.
