The invention relates to a touch feedback module and a touch device. The touch feedback module comprises an elastic plate, a plurality of piezoelectric motors and a plurality of supporting structures; the elastic plate is provided with a first surface and is provided with a plurality of through grooves penetrating through the elastic plate in the direction perpendicular to the first surface, the elastic plate is divided into a plate body and elastic pieces via the through grooves, one end of the elastic piece is fixedly connected with the plate body, and the other end forms a free end; the plurality of piezoelectric motors are at least partially arranged on the elastic pieces, the projection contours of the piezoelectric motors on the elastic plate in the direction perpendicular to the first surface fall into the contours of the through grooves, each piezoelectric motor corresponds to at least one elastic piece, and each elastic piece corresponds to one piezoelectric motor; the multiple supporting structures are arranged on the sides, close to the touch panel, of the elastic pieces; the supporting structures correspond to the elastic pieces one to one, and the projection contours of the supporting structures on the elastic plate in the direction perpendicular to the first surface fall into the contours of the through grooves corresponding to the supporting structures.
Description
technical field [0001] The invention relates to the field of touch technology, in particular to a touch feedback module and a touch device. Background technique [0002] For touch devices that require touch feedback and pressure perception, such as laptops, mobile phones, and vehicle-mounted equipment, in order to achieve the effects of touch feedback and pressure perception, a touch feedback module is provided in the touch device, and the touch feedback module There is a move towards all-in-one and no mechanical buttons. Traditional touch feedback mostly uses linear motor technology, and pressure sensing mostly uses strain gauge technology. With the development of science and technology, it is found that piezoelectric materials have the function of providing both touch feedback and pressure perception. Therefore, applying piezoelectric materials to touch feedback modules can obtain better effects of touch feedback and pressure perception. . However, the touch feedback mo...
