1. Chord board: Concert-level chord board imported from Germany, which is made of multi-layer hard colored wood with straight and symmetrical grain. provide
The lasting, balanced and stable nail grip ensures the stability of pitch and the smooth tuning action.
2. Sound board: The fish scale pine with radial cut texture is selected as the sound board material, and it is processed into solid wood sound boards with different thicknesses by hand matching technology, which is very in line with the sound law of piano and can maintain pure sound quality in various climatic conditions.
3. Rib wood: The rib wood made of white pine with radial cutting texture is selected, and the end of the rib wood completely extends to the edge of the soundboard pad to provide lasting and stable support, so that the soundboard can maintain a stable arch surface under the great tension of the strings.
4. Chord code: made of colored wood, providing lasting and stable structural performance and accurate and sensitive vibration transmission.
5. Complex vibrating string series: The complex vibrating string series before and after the middle and high-pitched area increases the fullness of timbre, especially the timbre in the high-pitched area.
6. Iron plate: an iron plate made by classical casting process, which supports the tension of piano strings of about 20 tons. It provides a strong structural guarantee for the overall structural stability of the piano.
7. Chord: The thread of lathe teeth is matched with German imported concert chord board, which provides lasting and stable nail holding force and smooth tuning action; The chrome-plated nail head provides good appearance quality and antirust performance.
8. Strings: Tin-plated rust-proof strings imported from Roslau, Germany, with round strings (with a round cross section), still maintain a beautiful timbre effect under strong tension.
9. Hammer: Hammer felt imported from Germany. The perfect combination of hardness and elasticity sets off the beautiful timbre of the piano.
10. percussion system: the classic design of percussion system, the selection of maple and the special treatment of percussion system felt effectively reduce the friction in the movement of percussion system, make the performance more sensitive and the action feedback more accurate.
1 1. Keyboard system: made of high-quality spruce, equipped with imported white keys and ebony matte black keys, comfortable and sensitive to touch keys.
12. medium plate: the medium plate manufacturing process without deformation is adopted (patent number: ZL 20 18 2 07 18865.5). Made of high-quality solid wood, no metal structure.
13. Casters: metal two-wheeled casters with flexible rotation and low noise.
14, pedal: full-function three-petal type.
15. Keyboard cover: A flip-type built-in descent control system is adopted, and the wall of the descent control device is thickened, which has a mute effect and no metal noise. All have been treated with rust prevention and oxidation prevention.
16 back column: solid wood back column can provide sufficient support.
17, adjustment gear: solid wood, without metal wrapping.
18, rotary striking device, connecting rod and damper: made of hard and high-quality wood.
19. Descending device: built-in hidden type.
