Tactile feedback module and tactile feedback device

Abstract

The invention relates to a tactile feedback module and a tactile feedback device. The tactile feedback module comprises a plurality of tactile feedback electrodes which are stacked in sequence, and each tactile feedback electrode comprises an insulating layer, a conductive layer and an elastic layer which are stacked in sequence; one of the plurality of conductive layers is selected to be defined as a common conductive layer, and the plurality of conductive layers except the common conductive layer are defined as an integrated conductive layer group; the common conducting layer is provided with a first electrode leading-out end, the collection conducting layer group is provided with a plurality of sub-electrode leading-out ends, and the plurality of sub-electrode leading-out ends jointly form a second electrode leading-out end; the input voltage of the first electrode leading-out end is different from the input voltage of the second electrode leading-out end. The technical effects are that the plurality of conductive layers of the integrated conductive layer group can form a voltage difference with the common conductive layer to generate an electric field force and provide an elastic deformation vibration effect, so that a tactile feedback effect is realized, and the situation that the accuracy of input voltage is influenced by dislocation of a plurality of tactile feedback electrodes during staggered superposition is reduced.

Description

technical field [0001] The invention relates to the field of tactile technology, in particular to a tactile feedback module and a tactile feedback device. Background technique [0002] In tactile feedback devices such as tactile keyboards, tactile steering wheels, and tactile massage chairs, a tactile feedback module for tactile feedback is included. The tactile feedback module includes a plurality of tactile feedback electrodes stacked. The tactile feedback electrodes include sequentially stacked insulating layers, conductive layers and elastic layers. The two conductive layers of adjacent tactile feedback electrodes apply voltages of different polarities. The electric field force generated by the difference makes the elastic layer located between the two conductive layers elastically deform and vibrate, thereby realizing the effect of tactile feedback. In order to ensure a good tactile feedback effect, two adjacent tactile feedback electrodes are usually arranged symmetri...
