Problems solved by technology
However, the existing touch screens or keyboards are all developing in the direction of light weight, portability, and simplification. Adding too many parts will not only increase the volume and weight of the product; it will also increase the difficulty of product design and improve Product defect rate; in addition, increasing energy-consuming components means increasing energy consumption, which is not conducive to energy-saving design of electronic products

The invention relates to a tactile feedback module, a touch screen, a keyboard and an electronic device. The tactile feedback module comprises at least two elastic control elements which are overlapped with each other, and each elastic control element comprises a conductive electrode layer and a porous elastic layer which are overlapped with each other; wherein the conductive electrode layer of one elastic force control element of the adjacent elastic force control elements is adjacent to the porous elastic layer of the other elastic force control element, and voltage signals with different polarities are applied to the conductive electrode layers of the adjacent elastic force control elements, so that when the tactile feedback module senses touch control, the porous elastic layer generates vibration feedback under the action of electric field force. Due to the fact that the multiple holes are additionally formed in the porous elastic layer, the elastic modulus of the porous elastic layer is reduced, and the porous elastic layer can generate large deformation vibration under small touch pressure. The vibration superposition of different porous elastic layers can generate a resonance effect, so that a user can feel stronger tactile feedback vibration sense under smaller touch pressure.
Description
technical field [0001] The present application relates to the field of touch technology, in particular to a tactile feedback module, a touch screen, a keyboard and an electronic device. Background technique [0002] In the touch screen or keyboard in the traditional technology, the touch feedback effect of each button is the same, and people generally can only determine whether the input action is completed by watching the input content. If the tactile feedback effect of the button can be increased, on the one hand, the user can judge whether the input action is completed only by the tactile feedback effect of the button, and on the other hand, the interaction performance between the user and the keyboard can be improved. For example, if the user can obtain different tactile feedback effects when pressing different buttons on the touch panel, the user experience can be effectively improved. [0003] However, if the touch screen or keyboard can bring tactile feedback to the ...
