Embodiment Construction

[0047]In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described here, and those skilled in the art can make similar improvements without departing from the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0048] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to th...

Abstract

The touch feedback module comprises a supporting plate, a connecting piece, a piezoelectric motor, a first limiting structure and a touch pad; the piezoelectric motor is fixed to the supporting plate through the connecting piece, the connecting piece has a set thickness in the stacking direction of the piezoelectric motor and the supporting plate; the projection contour of the connecting piece on the supporting plate in the stacking direction of the piezoelectric motor and the supporting plate is located in the projection contour of the piezoelectric motor on the supporting plate. The first limiting structure is arranged on the side, away from the supporting plate, of the piezoelectric motor, and the projection contour of the first limiting structure on the piezoelectric motor surrounds the projection contour of the connecting piece on the piezoelectric motor in the stacking direction of the piezoelectric motor and the first limiting structure. The touch pad is erected on the side, away from the piezoelectric motor, of the first limiting structure. The touch pad is directly pushed to act at multiple points, so that the vibration amplitude and strength of the touch pad are large, the vibration uniformity is good, meanwhile, the touch pad can be prevented from deforming downwards, and the obvious downward movement feeling is avoided.

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...
