Bottom cushion and weight placement are keys to minimize sound resonance
To make our piano lamp, we visited factories to understand how pianos are built.
The main structure of the piano is composed of a solid back post (usually beech or maple etc.) and metal wire frames. This is how strings are wound. In the final stage of manufacturing, piano builders will align the top cover to the main supporting structure. This is where PianoLight is placed. The solid wood beam supports the weight of the lamp and will not affect the piano structure. The piano builders insisted that a piano light needs to be a proper weight and have a cushion to minimize sound resonance.
