Soundboard structure for digital grand piano

Abstract

The invention discloses a soundboard structure for a digital grand piano, and belongs to the field of musical instrument manufacture. A sound absorption material (7) is adhered to the face, which faces a bottom plate (9), of a soundboard (6), and a damping material (5) is adhered to the other face of the soundboard (6). A steel wire (4) is arranged on the damping material (5), and faces the same direction as a skeleton (1). One end of the steel wire (4) is connected with a tightening mechanism (11) which is connected to a curved wall bar (16), and the other end of the steel wire (4) is fixed on a soundboard frame (12). Glass (3) is arranged on the steel wire (4). According to the invention, the sound absorption material has the function of suppressing harmonic peaks. By the damping material, sound coloring can be alleviated and even eliminated. Due to the arrangement of the steel wire, the shortcomings of residual vibration, resonance, even sympathetic vibration, melody distortion andthe like caused by the weak material strength of the soundboard which is thin and large in area can be overcome. The digital grand piano with the soundboard structure has simple and generous appearance which is the same as that of the conventional piano, and also has tone color which is as clear and pure as that of the conventional piano.

Description

technical field [0001] The invention relates to a digital piano, in particular to a sound board structure of a digital grand piano. It belongs to the field of musical instrument manufacturing. Background technique [0002] In terms of appearance, people like digital pianos to be the same as traditional pianos, and to follow the development of the piano for more than 300 years to achieve the unity of emotion and state of mind between the instrument and the player, which not only reflects the It not only outlines the contemporary people's pursuit of acoustic aesthetics, but also outlines the mutual promotion relationship between musical instruments and performers. The shape of the traditional piano is formed to meet the needs of its sound production method, while the sound production method of the digital piano is completely different from the traditional piano. One is the mechanical string vibration sound, and the other is the electric speaker vibration sound, which satisfie...

Problems solved by technology

[0005] The purpose of the present invention is to overcome the soundboard structure of digital grand pianos in the prior art. In order to realize the musical expression of traditional pianos, the structure of the vibration device adopted is complicated and difficult to adjust, especially in the face of the thin soundboard still existing in digital grand pianos. However, if the area is large, it is easy to produce forced vibration and cause sound dyeing, or even resonance, which makes the melody distorted. A digital grand piano soundboard structure with simple structure, convenient processing and low production cost is provided.
