Description

Keyboard with finely adjustable key stroke Technical Field The utility model relates to the technical field of keyboards, in particular to a keyboard with a finely adjustable key stroke. Background The keyboard is used as the most commonly used input device of a computer, the key hand feeling of the keyboard directly influences the use experience of users, different users have different requirements on key strokes due to the differences of typing habits, finger strength and operation preference, for example, users who are used to fast typing tend to have short key strokes so as to improve the input speed, and users who are engaged in character creation and need accurate input may prefer long key strokes so as to sense the feedback of keys. However, the key stroke of the conventional keyboard is fixed and cannot be adjusted according to the personalized requirement of the user, which not only reduces the comfort level of the user, but also possibly affects the input efficiency and accuracy, in addition, with the development of different types of keyboards such as mechanical keyboards, membrane keyboards and the like, the user has higher and higher expectations for functional diversity and personalized customization of the keyboards, and the existing partially-adjustable keyboards can mostly only perform simple key layout adjustment, and lack of effective solutions for adjusting the key stroke, so that the increasingly-increased diversified requirements of the user are difficult to meet.
