[0043] Reference Figures 1 to 5 , shows an electronic device and a schematic cross-sectional structure diagram of an embodiment of the present application, the electronic device may specifically include: a frame 10, a substrate 20, a key cap 30 and a plurality of vibration modules 50;

[0044] The frame 10 is provided with an opening 11, the substrate 20 is connected to the opening 11 of the frame, and the key cap 30 is disposed in the opening 11 and connected to the substrate 20;

[0045] A plurality of vibration modules 50 are disposed at intervals on a side of the substrate 20 away from the key cap 30 , and the vibration modules 50 can move toward the key cap 30 ;

[0046] When the pressure on the keycap 30 is transmitted to the substrate 20 , at least one vibration module 50 vibrates toward the substrate 20 , triggering the keycap 30 to generate vibration feedback;

[0047] The number and amplitude of the vibration modules 50 generating vibrations are related to the size, position and mode of the pressure applied to the keycap 30 , and the vibration feedback is related to the number and amplitude of the vibration modules 50 .

[0048] In the embodiment of the present application, different numbers of vibration modules 50 can be moved toward the keycap 30 and the vibration module 50 can be vibrated with different amplitudes to generate a variety of vibration modes, depending on the size of the pressure applied to the keycap 30, the different positions of the pressing action on the keycap 30, and the different modes of pressing the keycap 30 (such as pressing, clicking or sliding, etc.), thereby triggering the keycap 30 to generate a variety of different vibration feedbacks, thereby enriching the diversity of the vibration feedback function of the keycap 30, allowing the user to feel more delicate and accurate vibration feedback, and improving the user experience, without the need to trigger the key function when the pressing force reaches the trigger threshold.

[0049] Optionally, there may be a gap between the vibration module 50 of the present application and the substrate 20. In this case, when the vibration module 50 moves toward the substrate 20, it hits the substrate 20, causing the keycap 30 to vibrate. There may not be a gap between the vibration module 50 of the present application and the substrate 20. In this case, when the vibration module 50 moves toward the substrate 20, the vibration module 50 drives the substrate 20 and the keycap 30 to move in the same direction, generating vibration. The present application does not specifically limit whether there is a gap between the vibration module 50 and the substrate 20.

[0050] For example, in the embodiment of the present application, the user can press, click, touch the keycap 30, or slide on the keycap 30, so that the keycap 30 is subjected to pressure in various different modes, and the keycap 30 is subjected to pressure of various different magnitudes according to the different forces in various modes, and the corresponding vibration module 50 is activated according to the position where the user presses on the keycap 30. Based on the magnitude, position and mode of the pressure on the keycap 30, different numbers of vibration modules 50 close to or corresponding to the pressure position move with corresponding amplitudes or frequencies to generate vibrations, and the vibrations are transmitted to the keycap 30, thereby triggering the keycap 30 to generate a variety of different vibration feedbacks. For example, the amplitude or frequency of the vibration module 50 can be set as needed, and the embodiment of the present application is not limited to this.

[0051] In the embodiment of the present application, specifically, a plurality of vibration modules 50 are spaced and abutted against the substrate 20, and the plurality of vibration modules 50 are spaced and independent of each other, so that the plurality of vibration modules 50 can be independently controlled without affecting each other. Moreover, each vibration module 50 is in contact with the substrate 20, so that the vibration generated by the corresponding vibration module 50 can be transmitted to the keycap 30 along the substrate 20 more directly, quickly and effectively, and then generate vibration feedback, thereby improving the vibration feedback effect of the keycap 30 and avoiding the loss of force transmission during the vibration transmission process and affecting the vibration feedback.

[0052] For example, in an embodiment of the present application, the number of vibration modules 50 can be two, three, four, etc., and can be set according to the size of the keycap 30 and actual needs. The embodiment of the present application does not limit the specific number of vibration modules 50.

[0053] In the embodiment of the present application, for example, the frame 10 can also be called the middle frame, which supports the overall structure of the electronic device. The keycap 30 is used to receive external forces such as touch, click, slide and press applied by the user. The substrate 20 is used to support the keycap 30 and transmit the pressure deformation of the keycap 30. For example, the substrate 20 can be a steel sheet or a reinforced plate, which has a good force transmission effect, and the substrate 20 is elastic, and can also provide a buffer for the frame 10, reducing the impact of the vibration of the substrate 20 on the frame 10. In this way, when the keycap 30 is subjected to external force from the user, the steel sheet can have a good transmission effect on the above external force. For example, the steel sheet can have elasticity to produce deformation and then produce pressure changes. For example, Figure 2 As shown, the substrate 20 can be two separate structures, respectively located on both sides of the keycap 30. In addition, the substrate 20 can also be an integral structure, and the vibration module 50 can be staggered and distributed with the substrate 20 without affecting each other. The specific structural type of the substrate 20 may not be limited in the embodiment of the present application.

[0054] Specifically, in the embodiment of the present application, the opening 11 on the frame 10 is used to accommodate the keycap 30, and the opening 11 is adapted to the keycap 30, that is, the size and shape of the two are the same or similar, and the frame 10 and the keycap 30 can be flush, so that the appearance of the electronic device has good flatness and aesthetics. For example, the shape of the opening 11 can be a concave shape, or a rectangle, etc., and the embodiment of the present application does not limit the specific shape of the opening 11.

[0055] Optionally, in the embodiment of the present application, when the keycap 30 is subjected to the first pressing, the keycap 30 transmits the first pressure to the substrate 20; at least one vibration module 50 near the first pressing position moves toward the keycap 30 with the first amplitude, triggering the keycap 30 to generate the first vibration feedback. In this way, when the user presses, clicks or touches the keycap 30 with a small force, the small pressure on the force position of the keycap 30 is transmitted to the substrate 20, and at this time, a vibration module 50 that is closer to the force position or corresponds to the force position moves toward the keycap 30 with the first amplitude, triggering the keycap 30 to generate a relatively soft vibration feedback.

[0056] In the embodiment of the present application, for example, when the keycap 30 is subjected to the first pressing, a vibration module 50 close to the first pressing position may be arranged to move toward the keycap 30 with a larger second amplitude, triggering the keycap 30 to generate a larger first vibration feedback. In addition, multiple vibration modules 50, such as two or three, close to the first pressing position may be arranged to move toward the keycap 30 with a smaller first amplitude, triggering the keycap 30 to generate a first vibration feedback with a wider range. Alternatively, two or three vibration modules 50 close to the first pressing position may be arranged to move toward the keycap 30 with a larger second amplitude, triggering the keycap 30 to generate a stronger and wider first vibration feedback. The specific implementation method of the first vibration feedback may not be limited in the embodiment of the present application.

[0057] For example, in the embodiment of the present application, the first pressing force can be set to a pressure value less than or equal to the first preset threshold value, and the first preset threshold value can be set according to actual needs, such as 0.1N or 0.15N, etc., and the embodiment of the present application may not limit this. For example, the first amplitude can be 0.5mm or 1mm, etc., and can be debugged and set according to actual conditions, and the embodiment of the present application may not limit this.

[0058] In the embodiment of the present application, optionally, when the keycap 30 is subjected to a second pressure, the keycap 30 transmits a second pressure to the substrate 20; the multiple vibration modules 50 near the second pressing position move toward the keycap 30 with a second amplitude, triggering the keycap 30 to generate a second vibration feedback; wherein the second pressure is greater than the first pressure, and the second amplitude is greater than or equal to the first amplitude. In this way, when the user presses or strikes the keycap 30 with a greater force, the greater pressure on the force position of the keycap 30 is transmitted to the substrate 20, and at this time, the multiple vibration modules 50 near the force position or corresponding to the force position move toward the keycap 30 with the second amplitude, triggering the keycap 30 to generate a stronger vibration feedback.

[0059] Specifically, in the embodiment of the present application, the plurality of vibration modules 50 can move with a first amplitude, and since the plurality of vibration modules 50 generate vibrations together, the keycap 30 can be triggered to generate a relatively strong vibration feedback. In addition, the plurality of vibration modules 50 can also move with a second amplitude with a larger vibration amplitude, further enhancing the vibration feedback, and providing a stronger vibration feedback to the keycap 30 when a greater pressure is applied, further enriching the diversity of the vibration feedback of the keycap 30.

[0060] For example, in an embodiment of the present application, when the keycap 30 is subjected to a smaller first press and a larger second press respectively, a vibration module 50 close to the press position can be set to move toward the keycap 30, and the amplitude of the vibration module 50 under the first press is set to be smaller than the amplitude of the vibration module 50 under the second press, that is, the strength of the vibration feedback of the first press is smaller than the strength of the vibration feedback of the second press.

[0061] In other embodiments of the present application, when the keycap 30 is subjected to a smaller first press and a larger second press respectively, a plurality of vibration modules 50 (for example, two or three) close to the pressing position can be arranged to move toward the keycap 30, with a stronger vibration feedback, and the amplitude of the vibration module 50 under the first press is arranged to be smaller than the amplitude of the vibration module 50 under the second press, that is, the strength of the vibration feedback of the first press is smaller than the strength of the vibration feedback of the second press.

[0062] In other embodiments of the present application, when the keycap 30 is subjected to a smaller first press and a larger second press, for the first press, a vibration module 50 close to the press position can be set to vibrate, and for the second press, multiple vibration modules 50 (for example, two or three) close to the press position can be set to vibrate, and the vibration modules 50 are set to vibrate with the same amplitude. In this way, the vibration feedback of the first press and the second press can be more clearly distinguished, and the user's perception can be improved.

[0063] In other embodiments of the present application, when the keycap 30 is subjected to a smaller first press and a larger second press, for the first press, a vibration module 50 close to the press position can be set to vibrate, and for the second press, multiple vibration modules 50 (for example, two or three) close to the press position can be set to vibrate, and the vibration module 50 is set to vibrate with different amplitudes under the first press and the second press. For example, the amplitude of the vibration module 50 under the second press is set to be greater than the amplitude of the vibration module 50 under the first press, so that the user can more clearly distinguish the vibration feedback of the first press and the second press. Alternatively, the amplitude of the vibration module 50 under the second press is set to be less than the amplitude of the vibration module 50 under the first press. Since multiple vibration modules 50 vibrate under the second press, the user can also get a stronger and more obvious vibration feedback under the second press, further improving the richness of the vibration feedback felt by the user.

[0064] For example, in the embodiment of the present application, the second pressing pressure can be set to a pressure value greater than the second preset threshold value, and the second preset threshold value can be set according to actual needs, such as 0.1N or 0.15N, etc. The second preset threshold value can be the same as or different from the first preset threshold value, and the embodiment of the present application may not limit this. For example, the second amplitude can be 1mm or 1.5mm, etc., and can be debugged and set according to actual conditions, and the embodiment of the present application may not limit this.

[0065] Optionally, in the embodiment of the present application, when the keycap 30 is subjected to sliding pressure, the keycap 30 transmits a third pressure to the substrate 20; based on the sliding direction of the sliding pressure, the multiple vibration modules 50 move toward the keycap 30 in sequence with a third amplitude, triggering the keycap 30 to generate a third vibration feedback. In this way, when the user slides on the keycap 30, the keycap 30 is subjected to a sliding pressure mode with a pressure position and a force change. When the user's finger slides to the corresponding position of the keycap 30, the corresponding vibration module 50 moves toward the keycap 30 with a third amplitude. For example, there are three vibration modules 50. When the user's finger slides on the keycap 30 from top to bottom, the three vibration modules 50 move toward the keycap 30 from top to bottom in sequence with a third amplitude, triggering the keycap 30 to generate a third vibration feedback corresponding to the sliding pressure mode, further enriching the diversity of the vibration feedback of the keycap 30.

[0066] For example, in the embodiment of the present application, the sliding direction of the sliding press can be from top to bottom or from bottom to top, etc., and the embodiment of the present application may not limit this. For example, the third amplitude can be 0.5mm, 1mm or 1.5mm, etc., and can be adjusted and set according to the actual situation according to the pressure of the sliding on the keycap 30, and the embodiment of the present application may not limit this.

[0067] In the embodiment of the present application, optionally, the electronic device further includes a sensor 40, the sensor 40 is connected to the substrate 20, the substrate 20 is provided with an opening 21, the vibration module 50 is arranged corresponding to the opening 21, the sensor 40 is used to detect the size, position and mode of the pressure transmitted from the keycap 30 to the substrate 20; and the sensor 40 is electrically connected to the vibration module 50, based on the size, position and mode of the pressure detected by the sensor 40, the vibration module 50 moves toward the keycap 30 with a preset amount and a preset amplitude, triggering the keycap 30 to generate vibration feedback. For example, the sensor 40 can judge the size of the pressure on the substrate 20 according to the pressure value, and judge the force position according to the position with the maximum pressure value, and judge the mode of the pressure according to the gradual or sudden change of the pressure value, for example, gradual change to sliding, sudden change to pressing, etc. Based on the size, position and mode of the pressure detected by the sensor 40, the vibration module 50 moves toward the keycap 30 with a preset amount and a preset amplitude, triggering the keycap 30 to generate vibration feedback, the specific example is as before, and will not be repeated here.

[0068] For example, in the embodiment of the present application, the sensor 40 can be arranged around the opening 21 of the substrate 20, that is, multiple sensors 40 can be arranged on the substrate 20 around the periphery of the opening 21. In addition, multiple sensors 40 can also be symmetrically arranged on both sides of the opening 21, etc. The embodiment of the present application does not limit the specific arrangement of the sensor 40.

[0069] For example, in the embodiment of the present application, the sensor 40 can be bonded to the substrate 20 by an adhesive such as a double-sided adhesive, which has good connection reliability and stability, and is easy to operate and implement. In addition, the sensor 40 can also be connected to the substrate 20 by other means such as welding, and the embodiment of the present application does not limit the specific connection method between the sensor 40 and the substrate 20.

[0070] For example, the sensor 40 may be a pressure sensor with good sensitivity, so as to detect the touch, press, slide and other operations on the keycap 30. There may be multiple sensors 40, for example Figure 2 The number of sensors 40 is shown as two, and the two sensors 40 are respectively arranged at the two ends of the substrate 20. In addition, the number of sensors 40 can also be set to three, and they are connected to the two ends and the middle position of the substrate 20 at intervals. The specific number and arrangement of the sensors 40 in the embodiment of the present application are not limited, and can be arranged according to actual needs.

[0071] Optionally, in an embodiment of the present application, the electronic device includes a housing 51 and a magnetic component 52 and an inductor 53 arranged in the housing 51; the housing 51 is connected to the substrate 20, the inductor 53 is connected to the housing 51, and the inductor 53 is electrically connected to the sensor 40, the magnetic component 52 and the inductor 53 are arranged opposite to each other, and the magnetic component 52 is arranged on the side of the substrate 20 away from the keycap 30 and can move toward the keycap 30; when the sensor 40 detects that the pressure exerted on the keycap 30 is transmitted to the substrate 20, the inductor 53 is energized with a preset current, and drives the magnetic component 52 to move toward the keycap 30 with a preset amplitude, triggering the keycap 30 to generate vibration feedback.

[0072] In the embodiment of the present application, the housing 51 is used to provide a setting space for the magnetic part 52 and the inductor 53, and the magnetic part 52 and the inductor 53 are protected to avoid the influence of other structures in the electronic device. And the magnetic part 52 and the inductor 53 are arranged relative to each other, and an inductive magnetic field can be generated when the inductor 53 is energized. Since the inductor 53 is connected to the housing 51 and does not move relative to each other, the magnetic part 52 is driven by magnetic force to move toward the substrate 20 to generate vibration. In addition, based on the pressure magnitude of the keycap 30 detected by the sensor 40, the magnitude of the current of the inductor 53 can be set. For example, the preset current can be 1A or 2A, etc., and the specific value of the preset current can be not limited in the embodiment of the present application. The inductor 53 generates a magnetic field force through a preset current, driving the magnetic part 52 to vibrate with a preset amplitude, such as 1mm or 1.5mm, etc. And, when the pressure on the keycap 30 detected by the sensor 40 disappears, the inductor 53 can be set to disconnect the power.

[0073] For example, in the embodiment of the present application, the inductor 53 can be a coil, and a magnetic field force can be generated by energizing the coil. For example, the magnetic member 52 can be a magnet, so that when the magnet moves toward the keycap 30, a more obvious vibration can be generated. In addition, the magnetic member 52 can also be a energized coil, and the embodiment of the present application is not limited to this.

[0074] Optionally, in the embodiment of the present application, the inductor 53 includes a first coil 531 and a second coil 532 that are spaced apart, and the housing 51 includes a first side wall 511 and a second side wall 512 that are oppositely disposed; the first coil 531 is connected to the first side wall 511, the second coil 532 is connected to the second side wall 512, and the magnetic member 52 is spaced apart between the first coil 531 and the second coil 532. In this way, the first coil 531 and the second coil 532 are connected to the first side wall 511 and the second side wall 512 of the housing 51, respectively, to achieve a more reliable fixation of the first coil 531 and the second coil 532, and the magnetic member 52 is spaced apart between the first coil 531 and the second coil 532, and the first coil 531 and the second coil 532 on both sides are energized at the same time to generate a magnetic field force, so as to drive the magnetic member 52 in the middle to move, thereby achieving a better driving effect on the magnetic member 52.

[0075] That is, in the embodiment of the present application, for example, in one vibration module 50, the number of inductors 53, such as coils, can be two, the two coils are respectively connected to the front and rear sides of the housing 54, and the magnetic member 52 is arranged between the two coils and close to the key cap 30, so that the magnetic field force is generated by energizing the two coils on both sides to drive the magnetic member 52 in the middle to move, which can have a better driving effect on the magnetic member 52. In addition, one coil can be arranged opposite to the magnetic member 52, and the embodiment of the present application is not limited to this.

[0076] For example, in the embodiment of the present application, the magnetic part 52 can be a ferromagnetic part such as any one of a samarium cobalt magnet, a neodymium iron boron magnet and an iron oxide magnet. Since the ferromagnetic part has a simple structure and a low cost, when the magnetic part 52 is a ferromagnetic part, the structure of the magnetic part 52 can be relatively simple and the cost can be relatively low.

[0077] Optionally, in the embodiment of the present application, the vibration module 50 further includes a shell 54 and an elastic member 55, the magnetic member 52 is disposed in the shell 54, and the elastic member 55 is respectively connected to the shell 54 and the side of the housing 51 away from the substrate 20. In this way, the magnetic member 52 is installed and protected by the shell 54 to prevent the magnetic member 52 from being easily damaged by friction during movement, so that the magnetic member 52 maintains good magnetism and prolongs its service life. And the elastic member 55 provides a restoring force to the shell 54 and the magnetic member 52. When the magnetic field disappears, the magnetic member 52 and the shell 54 can be reset to the initial position under the restoring force of the elastic member 55, and the elastic member 55 can also provide a buffering effect on the reset process of the shell 54 and the magnetic member 52.

[0078] For example, in an embodiment of the present application, the elastic member 55 may be a spring or a spring sheet, etc., and one elastic member 55, two elastic members 55, or three elastic members 55, etc. may be provided on the shell 54. The provision may be made according to actual needs. The embodiment of the present application may not limit the specific type and specific number of the elastic member 55.

[0079] In the embodiment of the present application, the electronic device may further include a processor, which is electrically connected to the sensor 40 and the inductor 53 respectively; the processor controls the inductor 53 to be energized based on the pressure detected by the sensor 40. In this way, when the sensor 40 detects the pressure on the keycap 30, the inductor 53 may be energized by the processor to generate an electromagnetic field. Moreover, the magnitude of the energized current may be controlled according to the magnitude of the pressure detected by the sensor 40, thereby generating electromagnetic fields of different magnitudes and providing driving forces of different magnitudes to the magnetic member 52.

[0080] Optionally, in the embodiment of the present application, the electronic device further includes a connector 60 and a fastener 61; the substrate 20 has a portion extending out of the side wall of the housing 51 and connected to the frame 10, the connector 60 is respectively connected to the housing 51 and the portion of the substrate 20 extending out of the housing 51, and the fastener 61 is sequentially passed through the connector 60, the substrate 20 and the frame 10 to fix the connector 60 and the substrate 20 to the frame 10. In this way, a relatively stable connection between the housing 51 and the substrate 20 is achieved through the connector 60, and a relatively stable connection between the housing 51 of the solid-state key assembly and the substrate 20 and the frame 10 is achieved through the fastener 61, and the structure is simple and reliable, and the operation is easy.

[0081] For example, Figure 2 As shown, the connector 60 may be a connecting plate, and the connecting plate may be an L-shaped structure with two connecting plates, one of which is connected to the housing 51, and the other is connected to the substrate 20, so as to realize the connection between the connector 60 and the housing 51 and the substrate 20. For example, there may be two connectors 60, which are respectively arranged at both ends of the substrate 20, or there may be three, four or five connectors 60, etc., which may be arranged according to actual needs, and the specific number of the connectors 60 may not be limited in the embodiment of the present application.

[0082] In the embodiment of the present application, for example, the number of fasteners 61 can be two, and the two fasteners 61 are respectively arranged at the two ends of the substrate 20, and the positions of the two ends of the substrate 20 are respectively fixed, so as to improve the fixing reliability, be simple and reliable, and be easy to operate. In addition, the number of fasteners 61 can also be one, three, four, etc., and multiple fasteners 61 can be distributed at intervals. The embodiment of the present application may not limit the specific number and setting method of the fasteners 61. For example, the fasteners 61 can be bolts, studs, screws, etc., and the embodiment of the present application may not limit the specific type of the fasteners 61.

[0083] In the embodiment of the present application, optionally, a gap is provided between the keycap 30 and the frame 10 to prevent the vibration generated by the keycap 30 from being transmitted to the frame 10. In this way, when the keycap 30 is subjected to external forces such as touch, click, slide, and press applied by the user, since there is a gap between the keycap 30 and the opening 11 of the frame 10, the vibration generated by the keycap 30 under the external force will not be directly transmitted to the frame 10, thereby reducing the vibration generated by the frame 10 and improving the user experience.

[0085] In an embodiment of the present application, an electronic device includes: a frame, a substrate, a keycap, and a plurality of vibration modules; the frame is provided with an opening, the substrate is connected to the frame and extends out of the opening, the keycap is arranged in the opening and connected to the substrate; a plurality of vibration modules are spaced and abutted against a side of the substrate away from the keycap, and the vibration modules can move toward the keycap; when the pressure on the keycap is transmitted to the substrate, at least one vibration module vibrates toward the substrate, triggering the keycap to generate vibration feedback; wherein the number and amplitude of the vibration modules generating vibration are related to the magnitude, position and mode of the pressure on the keycap, and the vibration feedback is related to the number and amplitude of the vibration modules. In this way, according to the magnitude of different pressures on the keycap, the different positions of the pressing action on the keycap, and the different modes of pressing the keycap (such as pressing, clicking or sliding, etc.), different numbers of vibration modules can be moved toward the keycap, and the vibration modules can be vibrated with different amplitudes, generating multiple vibration modes, thereby triggering the keycap to generate multiple different vibration feedbacks, enriching the diversity of the vibration feedback function of the keycap, allowing the user to feel more delicate and accurate vibration feedback, and improving the user experience, without the need to trigger the key function when the pressing force reaches the trigger threshold.
