Qingdao Develops Giant Digital Piano
The "king of digital piano silvery wave" has made its debut in the Qingdao Music Square in this coastal city of east China's Shandong Province.
The giant piano, covering about 36 square meters, has been developed by the Engineering Acoustics Lab of Qingdao Marine University. Its fingerboard is 5 meters long and 1.2 meters wide. Its white fingerboard alone is 1.2 meters long, 0.22 meter wide and 0.1 meter thick, and weighs 40 kilograms.
The piano's body follows the traditional model of a triangle piano, with its surface made of marble, the white fingerboard, stainless steel and the black fingerboard, steel framework covered with high-hardness black resin. Even if it is put into water, it can still work normally.
With special treatment to its sensors, the piano can stand millions of times of punch. Since the piano is the biggest of its kind in the world, its developers have applied for the Guinness record.
A series of advanced technological means were adopted in design. The signals of fingerboard's movements are passed onto the underground control room via sensors before being processed by computer software. As a result, the piano sends off melodious sounds.
