Description

Technical Field

[0001] The utility model relates to the technical field of musical instrument manufacturing, in particular to a piano supporting soundboard. Background Art

[0002] The soundboard generally includes a resonance board and ribs. The ribs are mainly used to bear the pressure of the strings on the soundboard, thereby enhancing the elasticity of the soundboard. The ribs can also transmit the sound to various parts of the soundboard, causing the soundboard to resonate over a large area. When dealing with the combination of the ribs and the soundboard frame, how to increase the density of the soundboard and improve the sound quality of the piano is a technical problem that needs to be solved urgently in the industry. When the piano is played and makes a sound, the sound is transmitted from the back of the piano through the soundboard, affecting the sound effect.

[0003] A piano soundboard with an existing patent number of CN 205845475 U is prepared by splicing and gluing quarter-cut single-layer solid wood strips to retain the excellent performance of a solid wood soundboard and the mechanical stability of a composite soundboard.

[0004] The above scheme has the following disadvantages: the overall processing method is cumbersome and the production efficiency is low, and the glue is easy to fail after long-term use, and gaps are easy to form at the joints, resulting in asynchronous resonance of the various parts of the overall soundboard body, which ultimately leads to a significant decrease in tone. Utility Model Content

[0005] The utility model aims to provide a piano supporting soundboard.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] It includes a soundboard body, which is characterized in that: the soundboard body is made of solid wood, the wood grain of the soundboard body is an oblique texture, the outer wall of the soundboard body is fixedly provided with a plurality of ribs intersecting with the wood grain, the ribs are arranged parallel to each other, the soundboard body is wrapped with a soundboard frame, a reinforcing plate parallel to the ribs is extended on the inner side of the soundboard frame, the reinforcing plate is fixedly provided on a side of the soundboard body away from the ribs, the reinforcing plate partially covers the wood grain intersecting with the ribs, the angle between the wood grain with the oblique texture and the soundboard frame is 40-50 degrees, and the angle between the wood grain and the ribs is 30-60 degrees.

[0008] By adopting the above technical solution, the soundboard body made of solid wood can better exert the acoustic performance of the soundboard. At the same time, the natural forming feature makes it not easy to crack after long-term use, resulting in a low out-of-tune degree of the piano tone, small sound attenuation, and a purer and more comfortable sound in terms of hearing. At the same time, in terms of processing efficiency, a large amount of splicing labor can be saved, and the production efficiency is greatly improved. Wrapping the edge of the soundboard body with the soundboard frame can effectively prevent the solid wood soundboard body from cracking at the edge. The ribs and the reinforcement plate are fixedly installed with the soundboard body. Solid wood can be regarded as wooden boards spliced along the wood grain, and its weakest part is the joint, which is the same as that of the artificially spliced composite board. Therefore, the ribs and the reinforcement plate that intersect with the wood grain and maintain a certain angle can further strengthen and connect each part of the solid wood soundboard, avoiding cracks along the wood grain after long-term use of the soundboard body, ensuring that the soundboard body can emit sound stably for a long time. At the same time, the setting of the small-angle included angle can avoid overly suppressing the elasticity of the soundboard body while playing a strengthening role, enabling the soundboard body to resonate for a long time and ensuring a long and lingering tone.

[0009] Further, a pair of sound-transmitting holes are formed through the soundboard body, and the sound-transmitting holes are distributed diagonally on the soundboard body.

[0010] By adopting the above technical solution, the setting of the sound-transmitting holes can facilitate the direct transmission of the piano sound through the soundboard body, ensure the smooth emission of the piano sound, thereby improving the permeability of the piano sound and avoiding the situation of dull tone.

[0011] Further, a cylindrical sound cavity connecting the sound-transmitting holes is formed inside the soundboard body.

[0012] By adopting the above technical solution, the cylindrical sound cavity has a relatively regular shape. When the soundboard body resonates, the cylindrical sound cavity vibrates synchronously, and the generated piano sound is emitted through the sound-transmitting holes, reducing the out-of-tune degree of the piano tone and having a good effect of improving the sound quality.

[0013] In summary, the beneficial technical effects of the present utility model are as follows:

[0014] 1. Adopting solid wood material, a soundboard frame and a reinforcement plate with oblique wood grain, and the ribs and the reinforcement plate are fixedly and intersectingly installed with the soundboard body, thereby further strengthening and connecting each part of the solid wood soundboard, avoiding cracks along the wood grain after long-term use of the soundboard body, and ensuring a long-term stable sound-emitting effect of the soundboard body;

[0015] 2. Adopting the sound-transmitting holes, thereby ensuring the smooth emission of the piano sound, improving the permeability of the piano sound, and avoiding the situation of dull tone;

[0016] 3. Adopting the cylindrical sound cavity, thereby generating the effect that when the soundboard body resonates, the cylindrical sound cavity vibrates synchronously to jointly emit sound and improve the quality of the piano sound. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Please refer to Figures 1-3 , the present utility model provides the following technical solutions:

[0025] It includes a soundboard body 1, characterized in that: the soundboard body 1 is made of solid wood. The wood grain 2 of the soundboard body 1 is an oblique texture. A number of rib woods 3 intersecting with the wood grain 2 are fixedly arranged on the outer wall of the soundboard body 1. The rib woods 3 are arranged parallel to each other. The soundboard body 1 is wrapped with a soundboard frame 4. An inner side of the soundboard frame 4 extends with a reinforcing plate 5 parallel to the rib woods 3. The reinforcing plate 5 is fixedly arranged on a side of the soundboard body 1 away from the rib woods 3. The reinforcing plate 5 partially covers the wood grain 2 intersecting with the rib woods 3. The included angle between the oblique-textured wood grain 2 and the soundboard frame 4 is 40 - 50 degrees, and the included angle between the wood grain 2 and the rib woods 3 is 30 - 60 degrees. Using solid wood for the soundboard body 1 can better exert the acoustic performance of the soundboard, and the natural forming feature makes it not easy to produce cracks after long-term use, resulting in a low dissonance degree of the piano tone, small sound attenuation, a purer and more comfortable sound in terms of hearing, and at the same time, a large amount of splicing labor can be saved in the processing efficiency, greatly improving the production efficiency. Wrapping the edge of the soundboard body 1 with the soundboard frame 4 can effectively prevent the solid-wood soundboard body 1 from cracking at the edge. The rib woods 3 and the reinforcing plate 5 are fixedly installed on the soundboard body 1. The solid wood can be regarded as a wooden board spliced along the wood grain 2, and its weakest part is the joint, which is the same as that of the artificially spliced composite board. Therefore, the rib woods 3 and the reinforcing plate 5 intersecting with the wood grain 2 and maintaining a certain angle can further strengthen and connect various parts of the solid-wood soundboard, preventing the soundboard body 1 from cracking and generating gaps along the wood grain 2 after long-term use, ensuring that the soundboard body 1 can emit sound stably for a long time. At the same time, the setting of the small included angle can avoid overly suppressing the elasticity of the soundboard body 1 while playing a strengthening role, enabling the soundboard body 1 to resonate for a long time and ensuring a long and lingering tone.

[0026] The soundboard body 1 is penetrated with paired sound transmission holes 6. The sound transmission holes 6 are distributed diagonally on the soundboard body 1. The setting of the sound transmission holes 6 can facilitate the direct penetration of the piano sound through the soundboard body 1, ensuring the smooth emission of the piano sound, thereby improving the permeability of the piano sound and avoiding the situation of dull tone.

[0027] A cylindrical sound cavity 7 connecting the sound transmission holes 6 is opened inside the soundboard body 1. The outer shape of the cylindrical sound cavity 7 is relatively regular. When the soundboard body 1 resonates, the cylindrical sound cavity 7 vibrates synchronously, and the generated piano sound is emitted from the sound transmission holes 6, reducing the dissonance degree of the piano tone and having a good effect of improving the sound quality.
