Detailed Implementation

[0044] To make the technical problems solved by this utility model, the technical solutions adopted, and the technical effects achieved clearer, the technical solutions of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0045] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected" and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0046] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0047] Touchscreens are widely used in various scenarios, such as in-vehicle electronic devices, to enable navigation, music playback, and air conditioning adjustments. To provide a better and richer interactive experience, many vibration feedback screens integrate vibration feedback functionality. After a user touches the screen, the screen vibrates, allowing the user to perceive the operation without relying on sight. Vibration feedback after touch improves operational reliability in complex scenarios. For example, in a vehicle environment, when a driver touches the screen to confirm navigation, the driver can directly feel the screen vibration to confirm the operation was successful, avoiding distraction from looking at the screen and reducing safety hazards.

[0048] However, vibration feedback screens in related technologies generally include a display module and a housing. The entire rear circumference of the display module is flexibly connected to the housing via adhesive. When a user's finger touches the screen, the control system controls a vibration actuator to drive the display module to reciprocate relative to the housing, providing vibration feedback. The deformation of the adhesive on the rear of the display module provides the vibration displacement. However, this type of vibration feedback screen has the following problems:

[0049] First, the physical displacement feedback when the user presses the screen is weak, resulting in a lack of realism in the touch experience. Second, the deformation is provided solely by the adhesive between the display module and the casing, leading to weak vibration feedback. Due to the insufficient pressure and vibration feedback, the touchscreen provides a poor sense of realism, making it difficult for users to perceive touch operations promptly and limiting the interactive experience.

[0050] In order to solve the problems of touch screens in related technologies, this application provides a vibration feedback screen.

[0051] In this application's vibration feedback screen, when the user performs a touch operation on the front of the display module, the first connecting part connected to the rear edge area of ​​the display module deforms, and the cantilever in multiple vibration mechanisms deforms, allowing the user to have more obvious pressing feedback when pressing, and the user can perceive the change in pressing depth, thus providing a realistic operating experience.

[0052] When the user presses the display module, the pressure is transmitted through the display module and the second support to the cantilever. The cantilever bends and deforms under pressure. The pressure sensor detects the deformation of the cantilever, and the control module controls the vibration actuator based on the signal from the pressure sensor, allowing the user to feel vibration feedback. This forms a closed loop of touch operation and vibration confirmation, providing a realistic operating experience. The gaps between the front of the cantilever and the display module, and between the rear of the cantilever and the housing, are designed to allow the cantilever room to deform.

[0053] The vibration feedback screen of this application is applied to in-vehicle electronic devices. For example, the vibration feedback screen is installed on the center console or rear seat area of ​​a car. Users can directly control navigation map zooming and route planning, fine-tuning of air conditioning fan speed / temperature, track switching and volume control in the multimedia playback interface via touch operation, or activate voice assistant or driving mode switching functions by long-pressing or using a specific swipe trajectory. Of course, the vibration feedback screen of this application can also be applied to intelligent teaching equipment, smart home control equipment, medical equipment operating equipment, public self-service terminals, etc.

[0054] Please refer to the following. Figures 1 to 13 This document describes the vibration feedback screen of this application. It should be noted that, for ease of understanding the relative positions of the components, taking an image displayed on the front of the touch feedback screen facing the user as an example, the side closer to the user represents the front of all components and the vibration feedback screen, and the side away from the user represents the rear of all components and the vibration feedback screen. The user's left-right direction corresponds to the left-right direction of the vibration feedback screen, and the user's up-down direction corresponds to the up-down direction of the vibration feedback screen. For ease of understanding, in the accompanying drawings, the x-direction indicates the left-right direction, the y-direction indicates the up-down direction, and the z-direction indicates the front-back direction.

[0055] Reference Figures 1 to 3 The vibration feedback screen includes a display module 10, a housing 20, multiple vibration mechanisms 40, and a vibration driver 50.

[0056] The display module 10 includes a display panel and is used to provide visual display and touch input functions.

[0057] The housing 20 is located on the rear side of the display module and is used to support the display module 10. (Refer to...) Figure 10 , Figure 11A first connecting portion 30 is provided between the rear edge area of ​​the display module 10 and the front edge area of ​​the housing 20. The first connecting portion 30 connects the display module 10 and the housing 20. The first connecting portion 30 is a deformable structure, allowing relative displacement between the display module 10 and the housing 20 within a certain range. The first connecting portion 30 can be, but is not limited to, foam, silicone, etc. The rear side of the display module 10 and the front side of the housing 20 enclose a receiving cavity, which provides installation space for the vibration mechanism 40 and other modules and devices, and protects the vibration mechanism 40 and other devices.

[0058] Multiple vibration mechanisms 40 are all disposed within the receiving cavity, that is, between the display module 10 and the housing 20, and the multiple vibration mechanisms 40 are arranged at intervals and dispersedly. (Refer to...) Figures 5 to 8 , Figure 12 , Figure 13 The vibration mechanism 40 includes a cantilever 41, a pressure sensor 42, a first support 43, and a second support 44. The cantilever 41 has a first mounting portion 411 and a second mounting portion 412 at opposite ends. The cantilever 41 is an arm-shaped structure extending from the first mounting portion 411 to the second mounting portion 412. When the second mounting portion 412 is compressed, the cantilever 41 undergoes bending deformation. (Refer to...) Figure 3 , Figure 12 The rear side of the cantilever 41 is the housing 20, and a first gap d1 is maintained between the cantilever 41 and the housing 20. A first support part 43 is provided within the first gap. The first support part 43 is located between the rear side of the first mounting part 411 of the cantilever 41 and the housing 20. The first mounting part 411 is connected to the housing 20 through the first support part 43. (Refer to...) Figure 3 , Figure 12 The front side of the cantilever 41 is the display module 10. A second gap d2 is maintained between the cantilever 41 and the display module 10. A second support part 44 is provided within the second gap. The second support part 44 is located between the front side of the second mounting part 412 of the cantilever 41 and the display module 10. The second support part 44 is in contact with both the display module 10 and the second mounting part 412, so that the pressure on the display module 10 can be transmitted to the second mounting part 412 through the second support part 44.

[0059] Under the action of external force, the cantilever 41 can produce elastic deformation. The pressure sensor 42 is set on the cantilever 41. The pressure sensor 42 is used to detect the deformation signal of the cantilever 41 and send the deformation signal to the control module of the vibration feedback screen.

[0060] The vibration driver 50 is at least partially located within the receiving cavity and is connected to the display module 10. Exemplarily, the vibrator driver is connected to the rear side of the display module 10. When the vibration driver 50 is in operation, it generates vibrational energy that acts on the display module 10, thereby providing the user with tactile feedback through vibration.

[0061] The touch feedback of the vibration feedback screen in this application is divided into three stages: touch input stage, signal detection stage, and vibration feedback stage. In the touch input stage, when the user touches the front of the display module 10 and performs operations such as clicking or swiping, a certain pressure is applied to the display module 10. This pressure is transmitted through the display module 10 to the second support part 44, and then through the second support part 44 to the second mounting part 412 of the cantilever 41, causing the cantilever 41 to bend and deform under the pressure. In the signal detection stage, the pressure sensor 42 detects the deformation of the cantilever 41 in real time, and the processing module calculates the touch characteristics (such as pressing pressure and pressing speed) based on the signal. In the vibration feedback stage, the vibration driver 50 receives instructions from the control module, generates a vibration waveform, and transmits the vibration energy to the display module 10, and then to the user, providing vibration feedback.

[0062] The vibration feedback screen of this application has the following advantages:

[0063] First, the tactile feedback is enhanced through multi-point coordinated deformation. In addition to the deformable first connecting part 30, this application also provides multiple vibration mechanisms 40 distributed at multiple points within the receiving cavity between the rear side of the display module 10 and the housing 20. In this way, when the user touches and presses the front of the display module 10, the deformation of the first connecting part 30 and the multiple vibration mechanisms 40 allows the user to perceive a certain change in pressing depth, making the tactile sensation more realistic.

[0064] Secondly, the vibration feedback is enhanced through the design of the vibration mechanism 40. The cantilever 41 is arranged parallel to the display module 10, and its extension direction is perpendicular to the user's pressing direction. This allows the pressure of the touch press to act directly on the second mounting part 412 at one end of the cantilever 41, causing the cantilever 41 to bend and deform. This method of deformation of the cantilever 41 under pressure not only has good pressure detection sensitivity, but also facilitates the efficient conversion of vibration energy, reduces vibration energy loss, and allows the user to perceive the vibration feedback more clearly.

[0065] The cantilever 41 has deformation gaps (i.e., the first gap and the second gap) between its front and rear sides and the display module 10 and housing 20. This ensures that the cantilever 41 can bend freely without mechanical interference. This not only allows the cantilever 41 to bend and deform well to achieve accurate pressing pressure detection, but also reduces the loss of vibration energy transmitted from the vibration driver 50 to the front of the display module 10. This allows the vibration energy to be concentrated and transmitted to the touch area, improving the vibration feedback intensity and response speed.

[0066] Third, in related technical solutions, when a user touches the screen of the main display body, vibration feedback is triggered by changes in capacitance, which can only sense the touch position. This application sets a pressure sensor 42 on the cantilever 41 of the vibration mechanism 40. The pressure sensor 42 detects the deformation of the cantilever 41 and, in conjunction with the vibration driver 50, can provide a variety of interactive experiences. For example, different intensities of vibration feedback can be provided according to the pressure applied; a light press (low deformation) triggers a weak vibration, while a heavy press (high deformation) triggers a strong vibration. Alternatively, different vibration modes can be provided based on the duration of the press, such as a short press generating an instantaneous pulse and a long press generating a continuous vibration wave. Or, a combination of a heavy press and a long press can trigger specific functions, such as voice assistant activation.

[0067] Third, multiple vibration mechanisms 40 are arranged at intervals and spread out on the rear side of the display module 10. The pressure sensor 42 of each vibration mechanism 40 independently detects local deformation. When the user presses any position on the screen, the detection blind zone can be eliminated by superimposing the signals of adjacent pressure sensors 42. External vibration interference (such as vehicle bumps) can be filtered by differential calculation of the signals of multiple pressure sensors 42, reducing missed detections or false detections and improving the accuracy of pressure detection.

[0068] In one embodiment, the display module 10 is an OLED display module 10 or an LCD display module 10. Exemplarily, the display module 10 includes a glass cover and a display panel, the display panel being disposed in the middle region behind the glass cover, the edge region of the rear side of the glass cover being exposed, the housing 20 including a rear shell plate and a frame surrounding the rear shell plate, and a deformable first connecting portion 30 being provided between the edge region of the rear side of the glass cover plate and the frame of the housing 20.

[0069] In one embodiment, the first connecting part 30 can be one of foam, silicone, or rubber. The front side of the first connecting part 30 is bonded to the display module 10, and the rear side of the first connecting part 30 is bonded to the housing 20.

[0070] In one embodiment, the pressure sensor 42 is used to detect the deformation of the cantilever 41. The pressure sensor 42 can be, but is not limited to, a strain gauge sensor, a piezoelectric thin film sensor, a MEMS pressure sensor, a fiber optic grating sensor, or a flexible pressure sensor. The pressure sensor 42 can be attached to the surface of the cantilever 41 by means of adhesive, screw fastening, etc., or it can be inserted into a slot inside the cantilever 41 by insertion, or it can be directly embedded into the interior of the cantilever 41 during the manufacturing stage without being exposed.

[0071] In one embodiment, the pressure sensor 42 is attached to the surface of the cantilever 41.

[0072] In one embodiment, the vibration actuator 50 is a linear motor. Using a linear motor as the vibration source, a mass block is driven by electromagnetic force to reciprocate along a fixed axis, generating directional vibration. This method offers advantages such as low cost, low driving voltage, compatibility with vehicle power systems, and good vibration feedback. Compared to using high-voltage driven piezoelectric ceramics as the vibration actuator 50, using a linear motor eliminates the need for high-voltage drive, allowing for lower-cost implementation.

[0073] In one embodiment, the vibration driver 50 is attached to the side of the display module 10 near the housing 20. If the vibration driver 50 is fixed by screws, an additional bracket needs to be added between the display module 10 and the housing 20. In this embodiment, the vibration driver 50 is directly attached to the display module 10, which improves the vibration energy transmission efficiency, reduces vibration loss, and is also conducive to the thinner and lighter design of the screen body.

[0074] In one embodiment, the first support portion 43 is a rigid support portion. For example, the first support portion 43 is a metal column, a rigid plastic column, a metal protrusion, a rigid plastic protrusion, etc.

[0075] Optionally, the second support portion 44 is an elastic support portion. For example, the second support portion 44 is elastic silicone, elastic rubber, etc.

[0076] Reference Figures 5 to 9 , Figure 12 The rear side of the first mounting part 411 of the cantilever 41 is fixed relative to the housing 20 by a rigid first support part 43. The rear side of the second mounting part 412 of the cantilever 41 maintains a deformation gap with the housing 20. An elastic second support part 44 is provided between the front side of the second mounting part 412 of the cantilever 41 and the display module 10. The cantilever 41 is similar to a cantilever beam with the first mounting part 411 and the first support part 43 as fulcrums. The positions of the second mounting part 412 and the second support part 44 are the suspended ends of the cantilever 41. When the user touches the front of the display module 10 to perform a touch operation, the pressure is transmitted to the second support part 44 through the display module 10. The second support part 44 is deformed by the pressure. At the same time, the second support part 44 transmits the pressure to the second mounting part 412, causing the second mounting part 412 to move towards the housing 20. The cantilever 41 bends and deforms with the first mounting part 411 as the fulcrum. The main deformation area is located in the middle part of the second mounting part 412 and the cantilever 41.

[0077] The first support part 43 connects the first mounting part 411 of the cantilever 41 to the housing 20. When the first support part 43 adopts a rigid structure, it allows the cantilever 41 to use the first mounting part 411 as a stable fulcrum, avoiding fulcrum displacement due to elastic deformation of the cantilever 41. Thus, when the user presses the cantilever 41 to transmit pressure to the second mounting part 412 of the cantilever 41, the cantilever 41 can stably generate stable bending deformation with the location of the first mounting part 411 and the first support part 43 as the bending fulcrum. Secondly, the rigidity of the first support part 43 concentrates the bending deformation of the cantilever 41 in the area from the second mounting part 412 to the middle of the cantilever 41, amplifying the deformation and making pressure detection more sensitive. Furthermore, the cantilever 41 and the housing 20 are connected by the rigid first support part 43. The rigid support part can reflect vibration energy, reduce vibration energy loss, and allow the vibration energy generated by the driver to be transmitted to the display module 10 more concentratedly. Under the same vibration driver 50 working mode, the user can feel a more obvious vibration sensation.

[0078] The second support part 44 adopts an elastic structure. When the display module 10 is pressed, the pressure is directly applied to the second support part 44, and the second support part 44 deforms to provide the first layer of pressure feedback. Subsequently, the cantilever 41 bends and deforms to provide the second layer of pressure feedback. When the user presses, there is a progressive damping feeling, and the pressure feedback has a sense of layering. In addition, the elastic second support part 44 filters high-frequency vibration harmonics, which makes the vibration of the display module 10 softer and more natural.

[0079] With the first support part 43 being a rigid structure and the second support part 44 being an elastic structure, both the pressing feel and the vibration feedback effect can be taken into account.

[0080] In other embodiments, both the first support portion 43 and the second support portion 44 are elastic structures, or the first support portion 43 is an elastic structure and the second support portion 44 is a rigid structure.

[0081] In one embodiment, reference is made to Figures 6 to 8 , Figure 12 , Figure 13 To improve the pressure detection effect, the pressure sensor 42 is disposed between the first mounting portion 411 and the second mounting portion 412 of the cantilever 41. The cantilever 41 has a middle part located between the first mounting portion 411 and the second mounting portion 412. The pressure sensor 42 is disposed at least in the middle part of the arm. When the user presses the display module 10, the bending deformation of the middle part of the cantilever 41 is large. By placing the pressure sensor 42 in the middle part of the cantilever 41, the sensitivity of touch pressure detection can be improved. Furthermore, the amount of bending deformation in the middle part of the cantilever 41 is positively correlated with the pressing force, which enables sensitive detection of changes in the magnitude of touch pressure.

[0082] When the first support 43 is rigid and the second support 44 is elastic, and the pressure sensor 42 is positioned between the first mounting part 411 and the second mounting part 412, the connection point between the first mounting part 411 and the first support 43 of the cantilever 41 is the fulcrum for the bending deformation of the cantilever 41. The second mounting part 412 of the cantilever 41 bends and deforms around the fulcrum, with the deformation concentrated in the middle region of the cantilever 41. The middle region of the cantilever 41 is located in the region of maximum bending moment (region of maximum stress). Placing the pressure sensor 42 in this region improves the pressure detection sensitivity. In addition, placing the pressure sensor 42 in the middle region reduces assembly interference between the cantilever 41 and the display module 10, and between the cantilever 41 and the housing 20.

[0083] In one embodiment, reference is made to Figures 6 to 8 , Figure 12 The pressure sensor 42 is located on the side of the cantilever 41 closest to the display module 10, i.e., on the front side of the cantilever 41. When the user presses the display module 10, the pressure is transmitted to the cantilever 41, causing it to bend and deform. The front side of the cantilever 41 is stretched, while the rear side is compressed. Placing the pressure sensor 42 on the side with greater deformation allows it to detect the deformation of the cantilever 41 more sensitively. Secondly, within the cavity between the display module 10 and the housing 20, some display system-related modules and devices need to be arranged. Placing the pressure sensor 42 on the front side of the cantilever 41 reduces interference from modules and devices near the housing 20, thus protecting the pressure sensor 42.

[0084] In other embodiments, the pressure sensor 42 can also be built into the cantilever 41. In this case, the pressure sensor 42 can be located inside the first mounting part 411 and the middle part of the cantilever 41. Of course, the pressure sensor 42 can also be located on the rear side of the cantilever 41, and then adjusted accordingly according to other specific requirements.

[0085] In one embodiment, in order to balance the stable support for the display screen body, pressure detection, and vibration feedback effect, refer to Figure 3 , Figure 5 , Figure 9 The display module 10 includes at least two sets of cantilever assemblies 41, and each set of cantilever assemblies 41 includes at least two vibration mechanisms 40. The at least two sets of cantilever assemblies 41 are spaced apart along the left-right direction of the display module 10, and the at least two vibration mechanisms 40 in each set of cantilever assemblies 41 are spaced apart along the up-down direction of the display module 10.

[0086] The cantilever 41 components are spaced apart in the left and right directions, enabling left and right partitioned detection of touch pressure. For example, when a user clicks a virtual function button on the left side of the screen, the cantilever 41 component on the left can collaboratively detects the touch pressure on the left side through pressure sensors 42 at at least two locations, and provides press feedback and vibration feedback. Similarly, when a user clicks a function button on the right side, the vibration mechanism 40 distributed vertically in the right cantilever 41 component collaboratively detects the touch pressure, and provides press feedback and vibration feedback.

[0087] For example, the display module 10 includes a left cantilever 41 assembly and a right cantilever 41 assembly. The left cantilever 41 assembly includes two vibration mechanisms 40 located in the upper left and lower left regions, and the right cantilever 41 assembly includes two vibration mechanisms 40 located in the upper right and lower right regions. The four vibration mechanisms 40 are similarly arranged at the four corners of the rectangle. This arrangement of vibration mechanisms 40 can improve the sensitivity and accuracy of pressure detection for touch operations near the screen. For example, in the scenario of application in in-vehicle devices, users may frequently need to operate navigation buttons, air conditioning adjustment buttons, volume adjustment buttons, etc., in the left, right, and lower regions. This method of setting vibration mechanisms 40 in the upper left, lower left, upper right, and lower right regions can accurately detect pressure for most touch operations in in-vehicle touch operation scenarios.

[0088] When a user performs a horizontal touch operation across areas from left to right, such as dragging a map left or right, the touch trajectory can be detected and tracked collaboratively by the left and right cantilever components 41. The vibration mechanisms 40, spaced vertically within the cantilever components 41 on both sides, provide multiple pressure detection points, improving pressure detection accuracy and providing vibration feedback for left and right tracking. This allows the driver or co-driver to determine the correctness of the touch operation based on the direction of vibration without removing the device. Furthermore, when a user performs a vertical swipe operation on the left or right side, the touch trajectory can be tracked collaboratively by two vibration mechanisms 40 spaced vertically on that side. The mechanical support frame formed by the four corners of the vibration mechanisms 40 ensures the screen remains stable during sharp turns or when traversing bumpy roads, preventing screen shifting or accidental triggering due to concentrated mechanical stress, providing dual protection for safe interaction in complex driving environments.

[0089] Understandably, each cantilever 41 assembly may also include three or four vibration mechanisms 40.

[0090] Optionally, refer to Figures 5 to 9To provide a rich touch interaction experience, at least one vibration mechanism 40 is disposed between two adjacent sets of cantilever 41 components. This vibration mechanism 40 is a central vibration mechanism 401. In this embodiment, a central vibration mechanism 401 is added to the two adjacent sets of cantilever 41 components. When the user operates in the middle area of ​​the display module 10, the central vibration mechanism 401 can promptly capture the touch signal in the middle area. Furthermore, during the user's left-to-right swipe operation, the left cantilever 41 component tracks the starting point, the right cantilever 41 component tracks the ending point, and the central vibration mechanism 401 can compensate for pressure changes in the intermediate transition section, achieving real-time monitoring of the touch path. This "boundary on both sides, supplement in the middle" layout strategy retains the precise advantages of left and right partition detection while achieving a natural transition in full-area touch response through central reinforcement, providing a smooth and seamless interactive experience for multi-tasking parallel operation in automotive scenarios. In addition, the central vibration mechanism 401 improves the uniformity of the full-screen pressure feedback experience and also helps to strengthen the stability of the connection between the display module 10 and the housing 20.

[0091] Optionally, refer to Figure 5 , Figure 9 The vibration actuator 50 is positioned between two adjacent sets of cantilever 41 components. By placing the vibration actuator 50 between these adjacent cantilever 41 components, the vibration energy transmission path is optimized through a centrally located layout, allowing the vibration wave to radiate evenly across the entire screen area. Furthermore, since the vibration actuator 50 only needs to drive the display module 10 to vibrate, and does not need to drive the display module 10 and housing 20 together, a single vibration actuator 50 positioned in the central area can meet the vibration feedback requirements while controlling costs.

[0092] Of course, in other embodiments, multiple vibration drivers 50 may be provided, for example, one vibration driver 50 may be provided between two vibration mechanisms 40 on the left and one vibration driver 50 may be provided between two vibration mechanisms 40 on the right.

[0093] Optionally, refer to Figure 9 While the vibration actuator 50 is disposed on two adjacent sets of cantilever 41 assemblies, the central vibration mechanism 401 is spaced apart from the vibration actuator 50 in the vertical direction. For example, the central vibration mechanism 401 is disposed above the vibration actuator 50. This ensures that the central vibration mechanism 401 and the vibration actuator 50 are centrally arranged in the left-right direction of the display module 10. The vibration actuator 50 is located in the central position at the rear of the display module 10 to ensure that, with a single vibration actuator 50, vibration energy can be evenly distributed throughout the entire area.

[0094] In one embodiment, the vibration mechanism 40 in the cantilever 41 assembly is the main vibration mechanism 402. The cantilever 41 in the main vibration mechanism 402 is configured to extend from its first mounting portion 411 to its second mounting portion 412 along the left-right direction (i.e., along the x-direction) of the display module 10. The cantilever 41 of the main vibration mechanism 402 extends left and right, and its deformation direction is perpendicular to the gravity direction of the display module 10. Multiple spaced main vibration mechanisms 402 can reliably support the display module 10. Furthermore, the main vibration mechanism 402 can more sensitively detect the pressure of single-point clicks or left-right swipe operations in the left and right areas. Simultaneously, the cantilever 41 of the main vibration mechanism 402 can laterally diffuse vibration waves, providing the user with a haptic feedback sensation of left and right vibration during left-right swipe operations. The vibration direction is synchronized with the operation trajectory, making the feedback more intuitive.

[0095] Reference Figure 5 , Figure 6 , Figure 8 , Figure 9 The cantilever 41 of the main vibration mechanism 402 is configured such that, in the x-direction of the vibration feedback screen, the second mounting portion 412 is located away from the center of the vibration feedback screen relative to the first mounting portion 411. For example, the cantilever 41 of the left main vibration mechanism 402 is configured such that its second mounting portion 412 is located to the left of its first mounting portion 411, and the cantilever 41 of the right main vibration mechanism 402 is configured such that its second mounting portion 412 is located to the right of its first mounting portion 411. It can be understood that, taking the left main vibration mechanism 402 as an example, the cantilever 41 is arranged laterally. When the navigation button on the left side of the screen is pressed, the suspended second mounting portion 412 on the left side can be pressed backward and deformed, making the left main vibration mechanism 402 more sensitive to the pressing operation.

[0096] Optionally, the central vibration mechanism 401 is configured to extend from its first mounting portion 411 to its second mounting portion 412 along the vertical direction (i.e., along the y-direction) of the display module 10. The central vibration mechanism 401 extends perpendicularly to the cantilever 41 of the main vibration mechanism 402, which enhances torsional resistance and improves structural stability. For example, the central vibration mechanism 401 is positioned above the vibration actuator 50, and the second mounting portion 412 of the cantilever 41 of the central vibration mechanism 401 is located below the first mounting portion 411, providing better central support in the middle position.

[0097] In one embodiment, the vibration feedback screen includes a back cover 60, which is disposed on the side of the housing 20 opposite to the display module 10. The planar dimension of the back cover 60 is smaller than that of the housing 20, and the back cover 60 and the housing 20 enclose a rear cavity for accommodating some components. The portion between the display module 10 and the housing 20 serves as the screen body. Since the planar dimension of the back cover 60 is smaller than that of the screen body, the screen body appears thinner at its edges, resulting in a more aesthetically pleasing appearance. Furthermore, for thicker components, they can be accommodated within the space between the back cover 60 and the housing 20, preventing an increase in the overall thickness of the screen body.

[0098] Reference Figure 2 , Figure 3 , Figure 5 The housing 20 is provided with a clearance through hole 21. The end of the vibration driver 50 facing away from the display module 10 passes through the clearance through hole 21 and is accommodated in the rear cavity. The vibration driver 50 has a large overall thickness. Its front end is fixed to the rear side of the display module 10 by pasting or other means, and its rear end passes through the housing 20 and is accommodated in the rear cavity. The vibration driver 50 drives the vibration of the display module 10, which is conducive to the thin and light design of the screen body.

[0099] Optionally, the vibration feedback screen includes a first circuit board 70, which may also be referred to as a vibration feedback circuit board. The vibration driver 50 is electrically connected to the first circuit board 70, and / or the pressure sensor 42 is electrically connected to the first circuit board 70, which is disposed in the rear cavity.

[0100] Optionally, the first circuit board 70 is electrically connected to the TFT (thin-film transistor array) located within the receiving cavity, thereby providing pressure detection and vibration feedback while simultaneously allowing the display body to synchronously respond to touch operations and / or display content. For example, when a user clicks the map zoom-in button, the first circuit board 70 receives a pressure signal, drives the vibration driver 50 to vibrate briefly, and synchronously zooms in on the map display using the TFT.

[0101] In one embodiment, the first support portion 43 is a rigid structure and serves as a support column. The vibration feedback screen includes a first fastener, and the first support portion 43, the support column, and the housing 20 are locked together by the first fastener.

[0102] For example, the housing 20 is provided with a housing mounting hole, the mounting column is provided with a column mounting hole, and the first mounting part 411 of the cantilever 41 is provided with an arm mounting hole. The first fastener is a fastening screw, which passes through the arm mounting hole, the column mounting hole, and the housing mounting hole, thereby locking and fixing the first mounting part 411 of the cantilever 41, the first support part 43, and the housing 20 together. During the assembly of the whole machine, the vibration mechanism 40 and the housing 20 can be pre-assembled into a rear housing assembly using the first fastener, and then the rear housing assembly can be assembled with the display module 10, resulting in high assembly efficiency.

[0103] Optionally, refer to Figures 6 to 8 , Figure 13 The support column and cantilever 41 are integrally connected. The first support part 43 is a columnar structure that protrudes rearward relative to the first mounting part 411 of the cantilever 41. By configuring the support column and cantilever 41 as an integral component, the types of materials and assembly steps can be reduced.

[0104] In other embodiments, the support column may also be an integral structure that is integrally connected to the housing 20.
