Problems solved by technology

However, due to the cancellation of the traditional mechanical keyboard device, tactile feedback cannot be provided when inputting by clicking, and users often cannot quickly confirm whether the keystrokes have been recorded, forcing users to confirm visually, resulting in a slow input speed. Significantly reduced, affecting input efficiency and user experience

Description

Technical field [0001] The invention relates to a keyboard, in particular to a thin and light piezoelectric tactile feedback keyboard. Background technique [0002] The keyboard is an instruction and data input device used to operate equipment. It also refers to a group of function keys (such as typewriters, computer keyboards) arranged to operate a machine or equipment through the system. With the development of technology, despite the development of various alternative input technologies such as touch screens, voice recognition, and gesture recognition, keyboards are still the most commonly used devices for human input to computing devices. [0003] Users who can type at medium and high speeds tend to rely on tactile feedback to indicate that a button is pressed. The existing mechanical keyboard is spring loaded to provide tactile feedback. With the development of touch screen technology and the demand for miniaturization of handheld terminal devices, the thickness of the keyboa...
