KEYBED DEVICE

The present disclosure proposes a keybed device, including: a keybed support; a keybed arranged on the keybed support; a key height limiting column arranged in one-to-one correspondence with each key in the keybed, and an end of the key height limiting column is fixed on a bottom surface of the corresponding key; a pressure detecting device arranged in one-to-one correspondence under each key height limiting column to detect a pressing strength of each key height limiting column; and a flexible support structure arranged below each key height limiting column and located on at least one side of each pressure detection device. The keybed device includes a flexible support structure, which can avoid false triggering of the Aftertouch effect. A same depth is pressed down from the flexible support structure to obtain a consistent Aftertouch effect, and the performance effect is controllable.
