Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The utility model discloses mainly solved the inside well dish that is used for supporting keyboard and action machine of current piano and take place to warp because of the change of weather and the extension of live time, lead to the technical problem of the change of piano tone quality and feel. In addition, the original piano middle disc adopts wood as raw material, wood is consumed to a certain extent, people think of replacing the raw material by new material, but the light replaces the raw material without changing the structure and can not ensure the timbre and the tone quality; the utility model provides a novel structure can not take place to warp or warp very little because of weather and live time, guarantees piano tone quality and feels, but also has protected a piano center plate component of forest tree.
