Abstract: A spring keyboard is disclosed. The spring keyboard includes a key support (1) and multiple keys (2) disposed on the key support (1), A back end of a key (2) is connected with the key support (1) through a spring (3). The key support (1) includes a first rotary structure (41). The key (2) includes a second rotary structure (42) matched with the first rotary structure (41), and the key (2) can rotate up and down around the first rotary structure (41). The key support (1) further includes a limit seat (51), and the key (2) further includes a limit reverse buckle (52) matched with the limit seat (51). The limit reverse buckle (52) faces towards a front end of the one of the keys (2). The structure of the spring keyboard is reliable, effectively eliminating the hidden danger of disconnecting the key (2) from the key support (1).

Abstract: 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.
