In the touch feedback module 100, the driving circuit board 160 is used for transmitting a voltage signal to the piezoelectric motor 140 to achieve normal operation of the positive piezoelectric effect. The driving circuit board 160 is used for providing a voltage signal to the piezoelectric motor 140 to realize the normal operation of the inverse piezoelectric effect. In a specific arrangement, the driving circuit board 150 is a flexible circuit board, and may have other structures.
With continued reference to fig. 5 and 6, in particular, the driving circuit board 160 and the suspension plate 110 may be an integral structure.
In the touch feedback module 100, when the touch feedback module is specifically configured, the driving circuit board 160 is directly formed on the surface of the suspension plate 110 by using a deposition process or an injection molding process, so that the driving circuit board 160 and the suspension plate 110 are integrated, and the driving circuit board 160 and the suspension plate 110 are integrated, so that a connecting part and a connecting process of the driving circuit board 160 and the suspension plate 110 are omitted, and the assembly process is simplified. It should be noted that the piezoelectric motor 140 may be disposed on a side of the suspension plate 110 away from the driving circuit board 160, and at this time, the piezoelectric motor 140 and the driving circuit board 160 are electrically connected by providing a through hole on the suspension plate 110 and disposing a conductive member in the through hole, where the conductive member may be a conductive material injected into the through hole, such as conductive paste like silver paste, carbon paste, or the like, or a conductive wire coated in the through hole. The piezoelectric motor 140 may be disposed at a side of the suspension plate 110 close to the driving circuit board 160, and at this time, the upper and lower surface lead-out electrode wires of the piezoelectric motor 140 are connected to the driving circuit board 160.
The driving circuit board 160 is not limited to the above configuration, and specifically, the driving circuit board 160 and the external motherboard of the touch feedback module 100 may be an integrated structure.

In order to support the suspension plate 110 on the basis of the touch feedback module 100, as shown in fig. 7 and 8, a preferred embodiment is that a surface of the suspension plate 110 facing away from the touch pad 130 has at least one protrusion 111. When the suspension wing plate 110 is specifically arranged, the number of the protruding portions 111 may be one, or may be multiple, and the projection profile of the protruding portions 111 on the suspension wing plate 110 is smaller than the projection profile of the piezoelectric motor 140 on the suspension wing plate 110, so that the piezoelectric motor 140 can drive the suspension wing plate 110 to generate vibration without being influenced by gravity.
In the touch feedback module 100, the protruding portion 111 is used to support the overall structure, provide a fulcrum for the suspension plate 110 to vibrate, and assemble the overall structure to other components, and when the overall structure is specifically set, the protruding portion 111 and other components are assembled in a glue bonding manner, a thread locking manner, and a concave-convex buckling manner. And the suspension wing plate 110 can be conveniently and quickly installed in other members through the convex part 111 without additionally arranging a supporting structure, so that the number of parts is reduced, and the assembly process is simplified. Meanwhile, the protruding portion 111 limits the vibration amplitude of the two side edges of the suspended wing plate 110, and it can be understood that there is an included angle between the suspended wing plate 110 and the protruding portion 111, and since the suspended wing plate 110 is limited by the included angle when vibrating downward, the protruding portion 111 limits the vibration amplitude of the two side edges of the suspended wing plate 110.
The structure for supporting the suspended wing plate 110 is not limited to the above-mentioned projection 111, and as shown in fig. 9 and 10, in a preferred embodiment, a locking hole 112 is provided on the suspended wing plate 110, the locking hole 112 is opened to a surface of the suspended wing plate 110 facing away from the touch pad 130, and the locking hole 112 extends toward an inner portion of the suspended wing plate 110 by a certain depth in a direction perpendicular to the surface of the suspended wing plate 110 facing away from the touch pad 130.
In the touch feedback module 100, the locking hole 112 is locked with a locking structure disposed on another member, for example, the locking hole 112 is a threaded hole, and the other member is disposed with a stud, and the stud is used for supporting the suspension plate 110. The suspension wing plate 110 can be conveniently and quickly mounted to other members through the locking hole 112 without an additional supporting structure, so that the number of parts is reduced, and the assembly process is simplified.
The structural form for supporting the suspension plate 110 is not limited to the above structural form, as shown in fig. 11 and 12, the supporting structure may be directly the host housing 200, and the touch feedback module 100 is directly fixed to the host housing 200 by means of glue adhesion, screw locking, and male and female snap, so that a separate supporting structure is omitted. The main body case 200 is formed with a connection portion to provide a fulcrum of vibration for the suspended wing plate 110 and to reserve a vibration space for the suspended wing plate 110.
Additionally, the present invention further provides a touch device, which includes the touch feedback module 100 according to any of the above embodiments. The touch device includes, but is not limited to, a notebook computer, a mobile phone, a vehicle-mounted device, and other devices requiring touch feedback and pressure sensing. For example, if the touch device is a notebook computer, the touch feedback module 100 is an input touch feedback module of the notebook computer, which is also called a PC touch feedback module.
In the touch device, the touch feedback module 100 has the integrated structure of the transmission structure 120 and the suspension plate 110, or the integrated structure of the transmission structure 120 and the touch pad 130, so that fewer parts need to be assembled, the processing and assembling processes can be reduced, the assembly stability of the overall structure is higher, and the position accuracy of the touch feedback is better, therefore, the touch device with the touch feedback module 100 has fewer processing and assembling processes, and the assembly process is simpler and has higher assembly stability.
