This is Helen Chen, vice president, introducing the manufacturing principle of Helen castanets to blind lawyers: solid wood in the middle and leather on both sides. Now many piano factories in China are adopting this method.

When unscrupulous merchants belittle the Pearl River, they all say that the Pearl River uses a "composite soundboard". So who was the first person to use this "composite sound board"? Yamaha and Kawai in Japan. This soundboard with two sides of solid wood in the middle is used to being called "composite soundboard". At present, there are two kinds of piano soundboards: pure solid wood soundboard without skin and "composite soundboard" with skin on both sides of solid wood in the middle.

Yamaha YC series or above, Caesar Castle, Yingchang, etc. Use solid wood soundboard.
