Key, keyboard and keyboard control method

Abstract

The invention provides a key. The key comprises a key cap, a key shaft and a base. The key shaft is mounted on the base; and the key cap is slidably mounted on the base through the key shaft. The keycap is provided with a first magnetic source; a second magnetic source close to the first magnetic source by facing to the first magnetic source and mutually exclusive with the first magnetic source is arranged on the base; a backstop mechanism is arranged at one end, far away from the key cap, of the key shaft; a magnetic sensor is arranged at the bottom of the base; and a third magnetic source used for triggering the magnetic sensor is arranged at one end, far away from the key cap, of the key shaft. The output of a triggering signal is realized under the action of the third magnetic sourceand the magnetic sensor, so that the reliability of a working action and the stability of the performance can be improved and the response speed is high. The magnetic source of key cap motion is separated from the magnetic source of signal triggering, so that the mutual interference among different types of the magnetic sources can be reduced, the reliability of the key can be improved integrally,and the key life is prolonged.

Description

Technical field [0001] The invention relates to a new type of key, a keyboard with the key and a keyboard control method. Background technique [0002] The keyboard is one of the indispensable devices for modern people. There are many keys on the keyboard for users to input information or instructions by pressing them. Existing keys generate key signals in various ways. For example, mechanical keys use metal shrapnel to trigger circuit switches to generate key signals, or optical keys generate key switch signals by receiving or blocking light. However, each user has one or more different usage habits. Today, a single button with a single softness, hardness and sensitivity cannot meet the needs of different users or the same user in different states, and has a short service life. In today's technology, there are buttons that achieve return by only forming a repulsive force between an electromagnetic coil and a magnet, but this button consumes an unusual amount of power. C...

However, each user has one or more than two different usage habits. Today, a single softness and sensitivity button cannot meet the needs of different users or the same user in different states, and the service life is short.

In today's technology, there is a button that realizes the return stroke only through the repulsive force formed by the electromagnetic coil and the magnet, but this button consumes abnormal power
