The present invention can be embodied in many different forms other than those specifically described herein, and it will be apparent to those skilled in the art that similar modifications can be made without departing from the spirit and scope of the invention, and it is therefore not to be limited to the specific embodiments disclosed below.

It will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. 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, a mouse 10 according to an embodiment of the present invention includes an upper cover 100, a lower cover 200, and a vibration feedback structure 300. The upper cover 100 and the lower cover 200 are connected and enclosed to form an accommodating cavity, and the vibration feedback structure 300 is disposed in the accommodating cavity. The upper cover 100 has a key region 110, and the vibration feedback structure 300 is disposed opposite to the key region 110, so that when a user operates the mouse 10 to perform touch pressing (for example, clicking or long-time pressing) on the key region 110, the vibration feedback structure 300 can sense the pressing operation of the user and drive the key region 110 to vibrate to implement vibration feedback. The button region 110 feeds back vibration when the user presses, so that the touch feeling of the user's finger when pressing can be improved, and the operation experience of the mouse 10 can be improved. Further, the user can also determine whether the mouse 10 has recognized the pressing operation in the key area 110 based on whether or not the vibration is sensed.

In one embodiment, referring to fig. 2, the vibration feedback structure 300 includes a mounting frame 310, a support 320, a piezoceramic sheet 330, a controller 340, and a drive circuit 350. The mounting bracket 310 is fixed to the lower cover 200, and the mounting bracket 310 is a support carrier of the support member 320. In one embodiment, the mounting bracket 310 is a plastic bracket. Of course, the mounting bracket 310 may also be a metal bracket. The mounting frame 310 has a bearing surface 311 facing the button region 110, the bearing surface 311 is used for mounting the supporting member 320, in view of the operation experience of the mouse 10 by the user, the outer contour of the button region 110 is generally a curved surface, and correspondingly, the bearing surface 311 is an inclined surface matching the curved surface. In a specific application, the shape of the bearing surface 311 may be selected according to needs, and the bearing surface 311 is not limited to a slope. In one embodiment, the mounting bracket 310 may be a separate component from the vibration feedback structure 300 and be part of the lower cover 200, for example, the mounting bracket 310 and the lower cover 200 are integrally formed.

The supporter 320 includes a resilient piece 321, a first protrusion 322, and a second protrusion 323. The elastic sheet 321 has a bending performance under an external force, the elastic sheet 321 has a first surface 3211 and a second surface 3212 which are opposite to each other, the first surface 3211 faces away from the key region 110, and the second surface 3212 faces toward the key region 110. The first protrusion 322 and the second protrusion 323 are convexly disposed on the first surface 3211. Fig. 2 illustrates that the first protrusion 322 and the second protrusion 323 are respectively protruded from the edge of the elastic sheet 321 and located at two opposite sides of the elastic sheet 321. Of course, the first protrusion 322 and the second protrusion 323 may also be protruded on the middle region of the first surface 3211, and it is within the scope of the present application as long as the space between the first protrusion 322 and the second protrusion 323 is ensured. In addition, the elastic piece 321 is fixedly arranged on the bearing surface 311 through the first protrusion 322 and the second protrusion 323.

The piezoceramic sheet 330 is attached to at least one of the first surface 3211 and the second surface 3212. For example, fig. 2 illustrates that the piezoelectric ceramic plate 330 is attached to the second surface 3212, fig. 3 illustrates that the piezoelectric ceramic plate 330 is attached to the first surface 3211, and fig. 4 and 5 illustrate that the piezoelectric ceramic plate 330 is two in number and is respectively attached to the first surface 3211 and the second surface 3212. When the piezoelectric ceramic plate 330 is attached to the first surface 3211, a side of the piezoelectric ceramic plate 330 facing away from the first surface 3211 is opposite to a side of the first protrusion 322 and the second protrusion 323 facing away from the first surface 3211 and is close to the first surface 3211, which ensures that the piezoelectric ceramic plate 330 disposed on the first surface 3211 is spaced apart from the lower cover 200, and it can also be understood that the piezoelectric ceramic plate 330 is spaced apart from the mounting frame 310, so as to provide a sufficient space for the bending deformation of the piezoelectric ceramic plate 330. When the number of the piezoelectric ceramic pieces 330 is two and the piezoelectric ceramic pieces are respectively attached to the first surface 3211 and the second surface 3212, the thickness of each piezoelectric ceramic piece 330 can be reduced on the premise of ensuring that the total thickness of the two piezoelectric ceramic pieces 330 is not changed (without affecting the vibration strength), so that the excessive cost caused by the excessive thickness can be reduced.

The pattern formed by the projection of the piezoceramic sheet 330 on the first surface 3211 is located between the pattern formed by the projection of the first protrusion 322 on the first surface 3211 and the pattern formed by the projection of the second protrusion 323 on the first surface 3211. In this way, the region of the second surface 3212 opposite to the piezoceramic sheet 330 can bend and deform the elastic sheet 321 under the action of an external force (for example, a user presses the button region 110 to generate a pressing force applied to the second surface 3212), and the piezoceramic sheet 330 can synchronously bend and deform along with the elastic sheet 321 under the driving of the deformation of the elastic sheet 321. In one embodiment, the center region of the piezoceramic sheet 330 is opposite to the center region of the spring 321. Since the central region of the elastic sheet 321 has the maximum bending degree, the central region of the piezoelectric ceramic sheet 330 is disposed opposite to the central region of the elastic sheet 321, which is beneficial to maximizing the bending degree of the piezoelectric ceramic sheet 330.

It should be noted that, when the piezoelectric ceramic plate 330 is disposed on the first surface 3211, the second surface 3212 may directly contact with the key region 110 of the upper cover 100, or may indirectly contact with the key region. When the piezoelectric ceramic sheet 330 is disposed on the second surface 3212, the piezoelectric ceramic sheet 330 disposed on the second surface 3212 may directly contact with the key region 110 of the upper cover 100 or indirectly contact with the key region. For example, in an embodiment, the vibration feedback structure 300 further includes a bump 360, the bump 360 is disposed on a side of the second surface 3212 opposite to the first surface 3211, and the bump 360 is opposite to a central region of the piezoelectric ceramic plate 330, such that the vibration feedback structure 300 can be in contact connection with the key region 110 of the upper cover 100 through the bump 360, and external force is transmitted to the central region of the elastic plate 321 through the bump 360 to facilitate bending deformation of the central portion of the elastic plate 321. Of course, in other embodiments, the bump 360 may also be directly disposed on the key region 110 of the upper cover 100 (at this time, the bump 360 does not belong to a part of the vibration feedback structure 300), for example, the bump 360 and the upper cover 100 are integrally formed, and when the vibration feedback structure 300 is installed in the accommodating cavity, it is sufficient to ensure that the side of the second surface 3212 of the vibration feedback structure 300 facing the key region 110 is in contact connection with the bump 360.

The controller 340, the driving circuit 350 and the piezoelectric ceramic plate 330 are coupled to each other two by two. When the piezoelectric ceramic plate 330 is bent and deformed along with the elastic sheet 321 under the action of an external force, the piezoelectric ceramic plate 330 can generate a voltage based on the deformation, and the generated voltage corresponds to an induction signal. The controller 340 is configured to receive an induction signal generated by the piezoelectric ceramic plate 330, and control the driving circuit 350 to generate a driving signal through the induction signal, where the driving signal is a signal for applying an ac voltage to the piezoelectric ceramic plate 330, and the driving signal is used to drive the piezoelectric ceramic plate 330 to generate vibration. It should be noted that, the deformation degree of the piezoelectric ceramic plate 330 is different, and the generated voltages are different in magnitude, at this time, the controller 340 can obtain different sensing signals to generate different driving signals, so as to apply the ac voltages with different waveforms to the piezoelectric ceramic plate 330, thereby generating different vibration effects, specifically, different vibration effects can be classified, and may be classified into a light touch and a heavy pressure.

The driving circuit 350 may be fabricated on a Printed Circuit Board (PCB), which may be a main board for distinguishing the inside of the mouse 10, and when the vibration feedback structure 300 is installed in the accommodating cavity, the PCB is connected to the power supply inside the mouse 10. The PCB may also be a main board inside the mouse 10, in which case the driving circuit 350 does not belong to a part of the vibration feedback structure 300, and when the vibration feedback structure 300 is installed in the receiving cavity, the piezoelectric ceramic plate 330 and the driving circuit 350 are coupled. In an embodiment, the controller 340 may be disposed on a PCB board where the driving circuit 350 is disposed, and the controller 340 may be implemented by a Micro Controller Unit (MCU), and program instructions are installed in the MCU to enable the MCU to implement the functions of the controller 340. In this case, the controller 340 may also be coupled to a Central Processing Unit (CPU) through a serial bus. The CPU may configure various preset parameters in the controller 340 by modifying a host (host) file, and may even install program instructions in the controller 340 so that the MCU may implement the functions of the controller 340. In another possible implementation manner, the controller 340 may also be a CPU, and program instructions are installed in the CPU to enable the CPU to implement the functions of the controller 340. In addition, the MCU may further include a VCC port, a GND port, and the like, which are conventional ports in the MCU and will not be described herein again.

The utility model provides an in mouse 10, the both sides of shell fragment 321 can be fixed in mouse 10 inside through first arch 322 and second arch 323 (for example first arch 322 and second arch 323 are fixed in lower cover 200 through mounting bracket 360, or first arch 322 and second arch 323 directly set firmly in lower cover 200), and second surface 3212 towards pressing the regional 110 place one side of button, the second surface 3212 of shell fragment 321 can be pressed and make shell fragment 321 produce bending deformation under the exogenic action with the relative region of piezoceramics piece 330. Because the piezoelectric ceramic plate 330 is attached to the elastic sheet 321, the piezoelectric ceramic plate 330 can synchronously bend and deform under the driving of the deformation of the elastic sheet 321 and can generate an induction signal. The controller 340 can apply an ac voltage to the piezoceramic sheet 330 by the received sensing signal to cause it to vibrate, thereby implementing vibration feedback of the button region 110 of the mouse 10. Therefore, the elastic sheet 321 is fixed by adopting double supporting points, and the driving force strength of the whole structure can be greatly improved by utilizing the characteristic that the middle part of the elastic sheet 321 is pressed and bent, because the elastic sheet 321 adopts the mode that the first protrusions 322 and the second protrusions 323 on the two sides are fixed, the limitation on the bending motion of the middle part of the elastic sheet 321 after being pressed can be greatly weakened, the bending deformation of the piezoelectric ceramic sheet 330 can be fully released, and the vibration strength of the piezoelectric ceramic sheet 330 is increased. Compared with the prior art that the vibration strength of the piezoelectric ceramic plate 330 is increased by increasing the thickness of the piezoelectric ceramic plate 330 or increasing the alternating voltage applied to the piezoelectric ceramic plate 330, the scheme can further reduce the manufacturing cost of the overall structure and can also improve the overall rigidity of the elastic sheet 321.

In one embodiment, referring to fig. 2, the first protrusion 322 and the second protrusion 323 are elastic bodies to be elastically deformed when the second surface 3212 is pressed. The elastic body may be a rubber pad or a silicone pad, for example, and the first protrusion 322 and the second protrusion 323 as the elastic body may be adhered to the mounting bracket 310 by an adhesive 370, so as to fix the first protrusion 322 and the second protrusion 323 on the mounting bracket 310. The first protrusion 322 and the second protrusion 323 may also be adhesively fixed to the first surface 3211. Based on this, the elastic sheet 321 adopts the first protrusion 322 and the second protrusion 323 with elasticity to be flexibly fixed on the mounting frame 310 on the two opposite sides, and compared with the elastic sheet rigidly fixed on the mounting frame 310, the degree of bending deformation of the elastic sheet 321 is larger when the second surface 3212 of the elastic sheet 321 is under the action of external force with the same magnitude, so that the degree of bending deformation of the piezoelectric ceramic sheet 330 is larger, and the vibration degree of the piezoelectric ceramic sheet 330 is stronger.

In an embodiment, referring to fig. 5, the first protrusion 322 and the second protrusion 323 may also be integrally formed with the resilient piece 321, and in this case, the first protrusion 322 and the second protrusion 323 may be understood as an extension of the resilient piece 321. Thus, the elastic body and the adhesive 370 for connecting the elastic body and the mounting bracket 310 do not need to be separately provided, and the purpose of simplifying the vibration feedback structure 300 is achieved to some extent.

Further, the first protrusion 322 and the second protrusion 323 are both L-shaped brackets, each of the L-shaped brackets includes a first connecting section 324 and a second connecting section 325, the first connecting section 324 is connected to the first surface 3211, the first connecting section 324 extends toward a side away from the first surface 3211, and the second connecting section 325 is connected to a side of the first connecting section 324 opposite to the first surface 3211. Fig. 5 illustrates that the second connecting segment 325 extends towards the side away from the piezoceramic wafer 330, however, the second connecting segment 325 may also extend towards the side of the piezoceramic wafer 330, and this is not limited here. To secure the second connection segment 325, the vibration feedback structure 300 further includes a fastener 380, the fastener 380 may be, for example, a fastening screw, and the fastener 380 is inserted through the second connection segment 325 and the mounting bracket 310 to secure the L-shaped bracket to the mounting bracket 310.

In one embodiment, referring to fig. 1, the key region 110 includes a first region 111, a second region 112, and a third region 113 disposed between the first region 111 and the second region 112, and for convenience of illustration, a supporting member 320 and a piezoceramic sheet 330 associated therewith are defined to form a piezoelectric unit 301. Fig. 1 illustrates that the number of the piezoelectric units 301 is three and is respectively opposite to the first region 111, the second region 112 and the third region 113, and the three piezoelectric units 301 are mounted on the same mounting bracket 310, and it is understood that the number of the mounting bracket 310 may also be three and is in one-to-one correspondence with the three piezoelectric units 301.

With the above arrangement, when the mouse 10 is used, the first region 111 is pressed to implement the left button function of the mouse 10, and vibration feedback can be generated through the piezoelectric ceramic plate 330 disposed opposite to the region. The second region 112 is pressed to realize the right button function of the mouse 10, and can generate vibration feedback through the piezoelectric ceramic plate 330 arranged opposite to the region. The third region 113 is compressed for performing other functions of the mouse 10 (e.g., a scroll wheel function), and is capable of generating vibration feedback through the piezoceramic sheet 330 disposed opposite the region.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
