As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

Referring to fig. 1 and 2, a mouse 10 according to an embodiment of the present invention includes an upper cover 100, a lower cover 200, and a vibration feedback assembly 300. The upper cover 100 and the lower cover 200 are connected and enclosed to form an accommodating cavity, and the vibration feedback assembly 300 is disposed in the accommodating cavity. The upper cover 100 and the lower cover 200 form an outer housing of the mouse 10, and fig. 1 illustrates that the upper cover 100 and the lower cover 200 are detachably connected, and the detachable connection of the upper cover 100 and the lower cover 200 facilitates the installation of the vibration feedback assembly 300. It is understood that in other embodiments, the upper cover 100 and the lower cover 200 may be formed as a single piece. It should be noted that the vibration feedback component 300 of each embodiment of the present application is connected to the upper cover 100, so that when the user operates the mouse 10 to perform touch pressing (for example, clicking or long pressing) on the area of the upper cover 100 opposite to the vibration feedback component 300, the vibration feedback component 300 can sense the pressing operation of the user and drive the upper cover 100 to vibrate, thereby implementing vibration feedback, ensuring the touch feeling of the finger of the user when pressing, and improving the operation experience of the mouse 10. Also, the user can also determine whether the touch-and-press operation on the upper cover 100 has been recognized by the mouse 10 according to whether the vibration is sensed.

In one embodiment, referring to fig. 2, the number of the vibration feedback assemblies 300 is three, three vibration feedback assemblies 300 are arranged in sequence, and two adjacent vibration feedback assemblies 300 are arranged at intervals. In this way, the area of the upper cover 100 opposite to the vibration feedback assembly 300 can be divided into three areas, the three areas can be used for realizing the function of the left button, the function of the right button and other functions (such as the function of the scroll wheel) of the mouse 10, and corresponding vibration feedback can be generated when the three areas are realized. Wherein, fig. 2 illustrates that three sets of vibration feedback components 300 are sequentially arranged along the width direction of the mouse 10 and located at the front side of the upper cover 100 to satisfy the operation and use habits of the mouse 10 by the user. Of course, the present application does not limit the arrangement direction of the three sets of vibration feedback assemblies 300 without considering the operation and use habit of the user on the mouse 10.

In one embodiment, referring to fig. 3, the vibration feedback assembly 300 includes a spring 310, a piezoelectric vibration layer 320, and a transmission member 330. The elastic sheet 310 has a bending property under an external force, for example, the elastic sheet 310 in an embodiment may be a steel sheet with a good bending resistance, but is not limited thereto. The piezoelectric vibration layer 320 is attached to the elastic sheet 310, and the piezoelectric vibration layer 320 may be a piezoelectric ceramic sheet having a piezoelectric effect. The transmission member 330 includes a first connection block 331 and a second connection block 332, the first connection block 331 and the second connection block 332 are located at two opposite ends of the same side of the elastic sheet 100, and the first connection block 331 and the second connection block 332 are both disposed between the elastic sheet 310 and the upper cover 100. The first connecting block 331 and the second connecting block 332 may be elastic pads, such as rubber pads or silicone pads, and both the first connecting block 331 and the second connecting block 332 may be adhered between the upper cover 100 and the resilient plate 310. The first connecting block 331 and the second connecting block 332 may also be adhesive layers with a certain thickness, and at this time, two opposite sides of the elastic piece 310 are adhered to the upper cover 100 through the adhesive layers. The first connecting block 331 and the second connecting block 332 may also be integrally formed with the elastic sheet 310 to simplify the structure of the vibration feedback assembly 300. The area of the upper cover 100 opposite to the vibration feedback assembly 300 is pressed to make the elastic sheet 310 bend and deform by the transmission member 330, and the piezoelectric vibration layer 320 is driven by the deformation of the elastic sheet 310 to synchronously bend and deform and can generate vibration feedback on the pressed area of the upper cover 100 by the transmission member 330.

It should be noted that the working principle of the piezoelectric vibration layer 320 in the embodiments of the present application is to utilize the piezoelectric effect of the piezoelectric material, the piezoelectric vibration layer 320 can enable the piezoelectric material to be supplied with current when the piezoelectric material is subjected to bending deformation, the piezoelectric material can be deformed when the current is supplied to the piezoelectric material, if the magnitude or direction of the current changes, the piezoelectric material can be deformed to different extents and deformed directions, and the deformation is vibration. When a user touches the area of the upper cover 100 opposite to the vibration feedback assembly 300 with a finger, the piezoelectric vibration layer 320 can sense the touch operation of the user and can drive the upper cover 100 to generate vibration, thereby realizing vibration feedback. The upper cover 100 feeds back the vibration when the user finger contacts the upper cover 100, so that the touch feeling of the user finger when contacting the upper cover 100 can be improved, and the operation experience of the user can be improved. Also, the user can also determine whether the touch operation on the upper cover 100 has been recognized by the upper cover 100 according to whether the vibration is sensed.

Fig. 3 illustrates that the piezoelectric vibration layer 320 is attached to the spring plate 310 on the side facing the upper cover 100, and the piezoelectric vibration layer 320 is spaced from the upper cover 100. Of course, the piezoelectric vibration layer 320 may also be attached to the side of the elastic sheet 310 facing away from the upper cover 100, and in this case, the piezoelectric vibration layer 320 is spaced from the lower cover 200. Or, the piezoelectric vibration layer 320 may be attached to two opposite sides of the elastic piece 310, that is, one side of the elastic piece 310 facing the upper cover 100 is provided with the piezoelectric vibration layer 320 spaced from the upper cover 100, and one side of the elastic piece 310 facing away from the upper cover 100 is provided with another piezoelectric vibration layer 320 spaced from the lower cover 200. Under the premise of ensuring that the total thickness of the piezoelectric vibration layers 320 on the two opposite sides of the elastic sheet 310 is not changed, the vibration strength can be improved, the thickness of each piezoelectric vibration layer 320 can be reduced, and the overhigh cost caused by the excessively thick thickness can be further reduced.

It should be noted that, when the piezoelectric vibration layer 320 is disposed on the side of the elastic sheet 310 facing the upper cover 100, the piezoelectric vibration layer 320 disposed on the side of the elastic sheet 310 facing the upper cover 100 may cover the elastic sheet 310, that is, the elastic sheet 310 is laid on the whole surface. At this time, the first connection block 331 and the second connection block 332 may be indirectly connected to the spring plate 310 through the piezoelectric vibration layer 320. Of course, in other embodiments, the piezoelectric vibration layer 320 disposed on the side of the elastic sheet 310 facing the upper cover 100 may also be disposed between the first connection block 331 and the second connection block 332. In addition, when the number of the vibration feedback devices 300 is three, and the three vibration feedback devices 300 are arranged along the width direction of the mouse 10, the elastic piece 310 and the piezoelectric vibration layer 320 both extend along the length direction of the mouse 10, and the first connection block 331 and the second connection block 332 are located at two opposite ends of the elastic piece 310 in the length direction.

In the mouse 10 provided in the embodiments of the present invention, when the area of the upper cover 100 opposite to the vibration feedback assembly 300 is pressed, the pressing force is transmitted to the elastic sheet 310 through the transmission member 330, so that the elastic sheet 310 can be pressed by an external force to generate a bending deformation. Since the piezoelectric vibration layer 320 is attached to the elastic sheet 310, the piezoelectric vibration layer 320 can be driven by the elastic sheet 310 to synchronously bend and deform and generate an induction signal.

In an embodiment, the mouse 10 further includes a processor, which may be disposed inside the mouse 10, and when the piezoelectric vibration layer 320 is connected to the processor inside the mouse 10, the processor can apply an ac voltage to the piezoelectric vibration layer 320 through the received sensing signal to cause the piezoelectric vibration layer to vibrate, so as to implement vibration feedback of the pressed area of the upper cover 100. And the degree of deformation that piezoelectric vibration layer 320 pressurized produced is different, and the intensity of the induction signal of production is different, and the treater can obtain different induction signal this moment and generate different drive signal to apply the alternating voltage of different wave forms in piezoelectric vibration layer 320, thereby produce different vibration effects, specifically can carry out hierarchical processing with different vibration effects, can distinguish to be dabbed and heavy pressure.

It should be noted that the first connecting block 331 and the second connecting block 332 correspond to two fulcrums disposed on opposite sides of the elastic piece 310, and when one of the fulcrums is pressed, the other fulcrum can be bent greatly, i.e., a moment acting on the elastic piece 310 is formed (corresponding to a seesaw structure). Therefore, the elastic sheet 310 is fixed to the upper cover 100 by using the double-fulcrum point, and the driving force strength of the whole structure can be greatly improved by using the characteristic that one end of the elastic sheet 310 is pressed and bent, because the elastic sheet 310 can greatly weaken the limitation on the bending movement of the middle part of the elastic sheet 310 after being pressed by using the fixing mode of the first connecting block 331 and the second connecting block 332 on the two sides, the bending deformation of the piezoelectric vibration layer 320 can be fully released, and the vibration strength of the piezoelectric vibration layer 320 is increased. Compared with the prior art that the piezoelectric vibration layer 320 is directly attached to the upper cover 100 or a linear motor is adopted, the scheme has a simple structure and can enhance the vibration effect of vibration feedback.

In an embodiment, referring to fig. 5, the number of the vibration feedback assemblies 300 may also be a group, and the resilient tab 310 includes a main body portion 311, a first branch portion 312, a second branch portion 313 and a third branch portion 314. The first, second, and

third branch parts

312, 313, and 314 are connected to the body part 311, and the first, second, and

third branch parts

312, 313, and 314 are spaced apart from each other. The main body 311 extends along a first direction (the first direction is the direction in which the X axis extends in the figure), and the first branch 312, the second branch 313 and the third branch 314 all extend along a second direction (the second direction is the direction in which the Y axis extends in the figure), the first direction is perpendicular to the second direction, and the resilient piece 310 is in a chevron shape. In one embodiment, the first direction is parallel to the width extension direction of the mouse 10, and the second direction is parallel to the length extension direction of the mouse 10. The piezoelectric vibration layer 320 is attached to each of the first branch portion 312, the second branch portion 313 and the third branch portion 314, the first connecting block 331 is disposed between the end portion of the first branch portion 312 far from the main body portion 311 and the upper cover 100, the end portion of the second branch portion 313 far from the main body portion 311 and the upper cover 100, and the second connecting block 332 is disposed between the end portion of the third branch portion 314 far from the main body portion 311 and the upper cover 100.

In the case of the spring plate 310 having the chevron shape, the main body 311 may be a fixed end, and the first branch 312, the second branch 313 and the third branch 314 may all be compression bent ends, so that when the side of the branch where the first connecting block 331 is disposed is compressed, the degree of bending of the spring plate 310 can be increased, and the degree of bending of the piezoelectric vibration layer 320 can be increased accordingly, thereby increasing the vibration feedback strength.

In one embodiment, referring to fig. 4, the upper cover 100 includes a body 110, and a first button 121, a second button 122 and a third button 123 connected to the body 110. The first button 121, the second button 122, and the third button 123 are sequentially arranged and spaced along the width direction of the mouse 10. The first connecting block 331 of the first branch 312 is connected to the first button 121, the first connecting block 331 of the second branch 313 is connected to the second button 122, the first connecting block 331 of the third branch 314 is connected to the third button 123, and the second connecting block 332 of the main body 110 is connected to the main body 110. Thus, for the mouse 10 with physical keys, when the first key 121, the second key 122 or the third key 123 is pressed, the end of the elastic piece 310 with the first connecting block 331 can be bent relative to the end of the elastic piece 310 with the second connecting block 332, so as to generate vibration feedback. The first button 121, the second button 122 and the third button 123 may be respectively used for being pressed by a user, so as to respectively and correspondingly realize the left click, the scroll wheel and the right click functions of the mouse 10 when the user presses the buttons.

The cover 100 may not include the physical keys. Referring to fig. 3, the mouse 10 further includes a touch sensing layer 400, the touch sensing layer 400 is attached to the inner surface of the top cover 100, and at least one of the first connecting block 331 and the second connecting block 332 is disposed between the elastic sheet 310 and the touch sensing layer 400. For example, fig. 3 illustrates that the first connection block 331 and the second connection block 332 are both disposed between the elastic sheet 310 and the touch sensing layer 400. Of course, the first connecting block 331 may also be disposed between the elastic sheet 310 and the touch sensing layer 400, and the second connecting block 332 is disposed between the upper cover 100 and the elastic sheet 310 and located at the side of the touch sensing layer 400. The above arrangement can eliminate the physical buttons of the mouse 10, so that the outer surface of the upper cover 100 of the mouse 10 is continuous, thereby enhancing the aesthetic appearance of the mouse 10. In addition, the left click, right click and wheel functions of the mouse 10 can be realized by touching the area of the upper cover 100 opposite to the touch sensing layer 300, and the touch sensing layer 300 can realize the coordinate grabbing function after the area of the upper cover 100 opposite to the touch sensing layer 300 is pressed, thereby realizing fixed point vibration feedback.

A processor is connected to the first electrode layer 322 and the second electrode layer 323, and for example, the processor may be connected to the first electrode layer 322 and the second electrode layer 323 through a flexible circuit board. The processor is configured to transmit a driving signal to the first electrode layer 322 and the second electrode layer 323 when the piezoelectric vibration layer 320 deforms along with the elastic sheet 310, so that an alternating current feedback electric field is formed between the first electrode layer 322 and the second electrode layer 323, and the piezoelectric material layer 321 generates mechanical deformation under the action of the alternating current feedback electric field to form vibration feedback.
