As shown in fig. 1 to 4, the touch feedback structure provided by the embodiment of the application includes a control panel 1 and a piezoelectric device 2; wherein the piezoelectric device 2 can generate vibration after being energized;
Wherein, the control panel 1 is provided with a key area 11, and a vibration isolation area 12 is arranged on the periphery of the key area 11;

In the scheme provided by the embodiment of the application, the vibration isolation area 12 is arranged around the key area 11, so that the vibration transmission generated at the key area 11 can be effectively blocked. That is, a vibration collecting-isolating structure is formed on the control panel 1. It will be appreciated that the key areas 11 are defined on the surface of the control panel 1 by means of the vibration-collecting and isolating structure described above in the embodiment of the present application.
The embodiment of the application provides a technical scheme of a touch feedback structure, wherein the designated key area can be vibrated by reasonably collecting vibration generated by a piezoelectric device 2 and effectively isolating vibration, and the condition of vibration interference between adjacent key areas can be avoided.
The touch feedback structure provided by the embodiment of the application can regulate and control the vibration intensity and the range of the key region 11, so that a user can obtain good touch feedback, and the vibration effect during the touch feedback can be improved.
It will be appreciated that the piezoelectric device 2 is disposed on the key region 11, and when the piezoelectric device 2 is energized and vibrates, the key region 11 can generate a vibration effect therewith, so that after the key region 11 is touched, the key region 11 can generate a vibration feedback effect, and the design can enhance the user experience.
The manner of triggering the key area 11 may be, for example, a pressing trigger, or may be, of course, a touch trigger, which is not particularly limited in the embodiment of the present application.
The key area 11 is designed to be pressable and vibratable.
For example, an induction device is electrically connected to the control panel 1, and after the induction device obtains an induction signal that a user presses or touches the key region 11, the induction device may issue an instruction to control the piezoelectric device 2 to be electrified and generate vibration, so that the piezoelectric device 2 can drive the key region 11 to vibrate together, thereby achieving a vibration effect of touch feedback.
The control panel 1 is, for example, a circuit board with conductive lines.
The piezoelectric device 2 is electrically connected with the circuit board.
Further, the control panel 1 is made of, for example, a single or a plurality of material layers having a set thickness, rigidity, and elastic coefficient. The control panel 1 can be slightly deformed under a certain pressure.
For example, the material of the control panel 1 may be plastic, glass or metal, or a composite material of the above materials and other materials.
In some examples of the application, as shown in fig. 1 to 4, the control panel 1 has a first surface and a second surface disposed opposite to each other; the key region 11 and the vibration isolation region 12 are both provided on the first surface; a touch area 13 is disposed on the second surface, where the touch area 13 is disposed corresponding to the key area 11, and the key area 11 can be triggered when the touch area 13 is touched.
As shown in fig. 1, the touch area 13 is disposed on a second surface of the control panel 1 (for example, the second surface is a front surface of the control panel 1), and the touch area 13 is, for example, a touch point structure.
As shown in fig. 2, the key area 11 is disposed on the first surface of the control panel 1 (for example, the first surface is the back surface of the control panel 1), and is in a corresponding relationship with the position of the touch area 13, so that the user can directly trigger the key area 11 by touching or pressing the touch point structure.

When a plurality of key regions 11 are provided on the control panel 1, the plurality of key regions 11 are in non-contact with each other, so that vibration can be well isolated from each other, and mutual vibration interference can be avoided.
For example, through holes are provided in the vibration isolation areas 12 between any two adjacently disposed key areas 11, so that vibrations can be isolated more effectively.
Of course, the vibration isolation area 12 may not be provided with a through hole, and those skilled in the art may flexibly set the vibration isolation area according to the needs, which is not particularly limited herein.

For example, in the case where the key region 11 is a planar structure, a protrusion structure 111 (boss) may be disposed at a middle position of the planar structure, and the piezoelectric device 2 may be disposed on the protrusion structure 111, so that vibration feedback of the control panel 1 may be more obvious, that is, vibration effect during touch feedback may be improved.
In addition, the protruding structure 111 can also ensure the structural strength of the key region 11, and the vibration strength and range of the vibration region can be regulated and controlled.

For example, as shown in fig. 4, the key area 11 is a groove disposed on the first surface of the control panel 1, the bottom surface of the groove is configured as a planar structure, a protrusion structure 111 may be disposed at the middle position of the bottom surface of the groove, and the piezoelectric device 2 is disposed on the protrusion structure 111, so that the vibration feedback of the control panel 1 is more obvious, that is, the vibration effect during the touch feedback can be improved.

In addition, it should be noted that, a plurality of key areas 11 may be disposed on the same control panel 1, and the structural forms of the different key areas 11 may be the same, or may be different, and may be adjusted and disposed according to the needs of those skilled in the art, which is not particularly limited herein.
It should be understood that, on the control panel 1, the key area 11 may be the above-mentioned planar structure, the above-mentioned planar structure+protruding structure+recessed structure, or any one of them, or a combination of two or more of them.

In addition, the electrode structure of the piezoelectric ceramic sheet can be of a monocrystalline structure or a bimorph structure, or can be adhered and fixed on two side edges of the metal sheet and the carbon fiber sheet through the piezoelectric ceramic sheet to form a monocrystalline and/or bimorph structure.
For example, the thickness of the piezoelectric ceramic sheet may be set to 0.1mm to 2mm. And on the premise of the same size, the pressing feedback force can be improved.
In some examples of the application, the piezoelectric device 2 is adhesively secured to the key region 11.
In this way, the piezoelectric device 2 can be firmly arranged in the key region 11, and the fixing manner is relatively simple, without increasing the production cost. When the piezoelectric device 2 vibrates, the key region 11 also vibrates along with the piezoelectric device to generate a vibration effect of touch feedback.
The piezoelectric component 2 can be bonded to the key region 11, for example, by means of solder paste, silver paste or AFC.
The piezoelectric device 2 may be electrically connected to an external power source or the like by a solder wire so that the piezoelectric device 2 may be energized to generate vibration.
