SP鋼琴音源制作
Ciresa公司生產的音板和肋木材料精選自意大利北部費耶美山谷海拔1300-1400米之間的紅杉。音板采用鑲嵌榫接工藝以保證音板的牢固穩定和最大限度減少聲音傳遞的衰減。橫向和豎向都按設計好的角度壓成球面弧形后被粘合在音板框上,獲得圓潤柔美的音色。由15層山毛櫸木碾壓而成的著名的德國Delignit弦軸板保證音準的穩定性。
采用山毛櫸多層板并用數控機床一次切割成型的整體背架具有極高的強度以承受琴弦的極大張力,以保證鋼琴的堅固耐用。真空鑄造的鐵板采用數控機床鉆孔精確定位了弦軸釘、琴弦和定弦鈕的位置。
The Manufacturing of the Strung-Back
The soundboard is made with the superior selection of Red Spruce resonance woods, supplied by Ciresa - Val di Fiemme. The panels of the soundboard are mortised together to guarantee complete solidity and resistance. Each soundboard is slightly curved before it is glued to the wooden frame; this is an exclusive procedure that optimizes its resonance. The reputed Delignit pin block, constructed in 15-ply beech, ensures excellent constancy and endurance of tuning.
The wooden frame is obtained through a unique and valuable technique that grants the longest stability of the whole structure. In fact it is made of a single multilayered beech panel, carved on the inside with innovative CNC machines.
A grey cast-iron alloy has been designed specifically to be manufactured in a single block with the highest resistance to stress and vibration. Holes are drilled with a high precision machine controlled by a computer, ensuring that all the tuning pins, agrafes and strings are always correctly positioned.
