Abstract

The invention provides a key, and a keyboard which comprises a plurality of keys. The key comprises a key shell, an electrostatic generator element which is arranged below the key shell and can produce electric energy by utilizing a contact electrification effect, and a key sensing element, wherein the position of the key shell corresponds to that of the key sensing element; and when the key shell is pressed, an electric signal is produced by the electrostatic generator element while a key signal is produced by the sensing element. The key and the keyboard provided by the invention have the advantage that the mechanical energy produced when the key shell is pressed is converted to electric energy on the premise that normal operation of the key is not influenced.

Description

technical field [0001] The invention relates to an electronic device, in particular to a key and a keyboard which recover and utilize the mechanical energy of hitting the key. Background technique [0002] A keyboard is a group of function keys (such as typewriters, computer keyboards) that are systematically arranged to operate a machine or device, and it is also a part of a keyboard instrument, such as a piano, digital piano, or electronic keyboard. The structure of the keys in the keyboard usually includes a key casing and a base plate correspondingly arranged below the key casing, including a key circuit and its inductive element, the key casing and the base plate are connected by an elastic element, when the key casing is tapped, the key is pressed. The sensing element under the shell senses the tap to generate a key signal, and transmits the key signal to the processor and other receiving devices through the keyboard circuit; when the key shell bounces, the sensing ele...
