PIANO KEY ASSEMBLY
Document Type and Number:
WIPO Patent Application WO/2020/224204
Kind Code:
A1
Abstract:
A piano key assembly (1), comprising: a keyboard support (11); a keyboard disposed on the keyboard support (11); piano key height limiting columns (13) arranged in one-to-one correspondence with keys in a keyboard, one end of which is fixed to a lower surface of a corresponding piano key; pressure detection devices (14) arranged in one-to-one correspondence below the piano key height limiting columns (13) to detect pressing forces of the piano key height limiting columns (13); and flexible support structures (15) arranged below the piano key height limiting columns (13) and each located on at least one side of the pressure detection devices (14), the flexible support structures (15) comprising a flexible material. The addition of the flexible support structures (15) to the piano key assembly (1) may prevent a mistakenly triggered aftertouch effect, and pressing downward is carried out to the same depth from the flexible support structures (15) so that a highly consistent aftertouch effect is obtainable, and the playing effect is controllable. At the same time, a varistor sensor (142) is used to detect aftertouch and the force of the aftertouch, and the cost is low.
