[0030] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0031] 1-8 , an embodiment of the present invention provides a touch-vibration device 10 for electrically connecting to a terminal device. The touch-vibration device 10 includes a stator assembly 11 for fixing to the terminal device, a vibrator assembly 12 spaced apart from one side of the stator assembly 11, and a touch assembly 13 connected to a side of the vibrator assembly 12 facing away from the stator assembly 11. The touch assembly 13 is configured to detect pressure information in a first direction.

[0032] The stator assembly 11 includes a fixing frame 111 for fixing to the terminal device and a magnetic circuit system fixed to the fixing frame 111, wherein the magnetic circuit system has a magnetic gap;

[0033] The vibrator assembly 12 includes a shell 121 elastically connected to the fixing frame 111 and covered outside the magnetic circuit system, and a solenoid assembly 122 fixed to the shell 121 and located in the magnetic gap. The magnetic circuit system is used to drive the solenoid assembly 122 to reciprocate in the second direction, and the first direction and the second direction have an angle.

[0034] In this embodiment, it can be known that the stator assembly 11 and the vibrator assembly 12 together constitute a vibration motor. When the user presses the touch assembly 13, the touch assembly 13 detects the pressing information in the first direction, and the magnetic circuit system provides the solenoid assembly 122 with a driving force to reciprocate in the second direction, thereby enabling the vibrator assembly 12 to reciprocate in the second direction as a whole. Since the touch assembly 13 is connected to the vibrator assembly 12, and the first direction and the second direction have an angle, the user can press the touch assembly 13 in the first direction while experiencing the vibration tactile sensation in the second direction. This arrangement reduces the impact of the driving force in the non-pressing direction of the touch vibration device 10, and has a small space requirement for the terminal device in the pressing direction, and can be adapted to various types of terminal devices.

[0035] It can be known that the first direction may be the z direction, and the second direction may be the x direction or the y direction.

[0036] Further, referring to Figures 6 to 8, the fixing frame 111 includes a base plate 1111 for fixing to the terminal device and a fixing frame 1112 fixedly connected to the side of the base plate 1111 facing the vibrator assembly 12. The fixing frame 1112 is annular, and the shell 121 is elastically connected to both ends of the fixing frame 1112 in the second direction and is covered outside the fixing frame 1112.

[0037] In this embodiment, the base plate 1111 is a rectangular metal plate with its length extending parallel to the second direction. The fixing frame 1112 is adhesively fixed to the base plate 1111, with its projection toward the base plate 1111 located within the base plate 1111. The fixing frame 1112 is a rectangular frame with its short sides perpendicular to the second direction. The housing 121 is elastically connected to the short sides of the fixing frame 1112 and covers the short sides of the fixing frame 1112. The magnetic circuit system is fixed between the two opposing long sides of the fixing frame 1112. This arrangement facilitates securing the magnetic circuit system within the fixing frame 111 and forming a magnetic gap.

[0038] In other embodiments, the fixing frame 1112 can also be fixed to the base plate 1111 by snapping or integral molding. The fixing frame 1112 does not have to be a rectangular frame, as long as the center of the fixing frame 1112 has space for fixing the magnetic circuit system and can form a magnetic gap of a certain distance.

[0039] Further, referring to FIG. 8 , the fixing frame 1112 extends perpendicularly to the two side walls in the second direction toward the vibrator assembly 12 to form two extension portions, and the magnetic circuit system is fixed to the inner walls of the two extension portions.

[0040] In this embodiment, two extensions are formed between the two opposite long sides of the fixing frame 1112 and extend toward the vibrator assembly 12. The two extensions fix the magnetic circuit system and form a magnetic gap. When the solenoid assembly 122 is energized, it can vibrate between the two extensions.

[0041] Further, referring to Figure 8, the shell 121 includes a top plate 1211 spaced apart from the fixing frame 111 and two side plates 1212 extending from both ends of the top plate 1211 toward the stator assembly 11. The two side plates 1212 are elastic and elastically connected to the fixing frame 111 in the second direction.

[0042] In this embodiment, the length of the top plate 1211 extends parallel to the second direction. The top plate 1211 is arranged parallel to the bottom plate 1111 of the fixed frame 111. The side plates 1212 extending from both ends of the top plate 1211 toward the stator assembly 11 are perpendicular to the top plate 1211. The short sides of the fixed frame 1112 abut against the opposing inner walls of the side plates 1212. Specifically, when the magnetic circuit system drives the solenoid assembly 122 to reciprocate in the second direction, the housing 121 reciprocates in the second direction along with the solenoid assembly 122. The side plates 1212 of the housing 121 are elastically connected to the fixed frame 1112, causing the housing 121 to vibrate.

[0043] The housing 121 not only secures the solenoid assembly 122 but also provides an elastic connection between the stator assembly 11 and the vibrator assembly 12, acting as an elastic component in the vibration motor. Compared to vibration motors in related art, the housing 121 in this embodiment has a clever structure, significantly simplifying the structure of the elastic components in the vibration motor.

[0044] It can be known that the top plate 1211 and the two side plates 1212 can be integrally formed, and the shell 121 can be made of elastic metal material such as stainless steel.

[0045] Further, referring to Figures 6 and 8, the solenoid assembly 122 includes a pole core 1221 fixed on the top plate 1211 and a plurality of coils 1222 sleeved on the pole core 1221; the magnetic circuit system includes a plurality of magnets 112 fixed to the fixing frame 111, and the plurality of magnets 112 are distributed on both sides of the coil 1222 with the pole core 1221 as the axis to form two groups of magnets 112, and a magnetic gap is formed between the two groups of magnets 112.

[0046] In this embodiment, the pole core 1221 includes a plurality of fixing portions fixed to the side of the top plate 1211 facing the stator assembly 11 and a connecting portion fixed between two adjacent fixing portions. The plurality of fixing portions are spaced apart along the second direction, and each coil 1222 is sleeved on each connecting portion. A plurality of magnetic steels 112 are arranged corresponding to each coil 1222 and fixed to the extension portion. Preferably, each magnetic steel 112 is symmetrically distributed on both sides of the coil 1222 along a third direction with the pole core 1221 as the axis. The third direction has an angle with both the first direction and the second direction. Optionally, the third direction is perpendicular to the first direction and the second direction. Optionally, each magnetic steel 112 is glued and fixed to the fixing frame 111. In other embodiments, the plurality of magnetic steels 112 can also be asymmetrically distributed on both sides of the coil 1222.

[0047] Furthermore, referring to the figure, the magnetization direction of each magnetic steel 112 is perpendicular to the second direction, and the magnetization directions of each magnetic steel 112 distributed on both sides of the coil 1222 with the pole core 1221 as the axis are opposite.

[0048] In this embodiment, the first direction is perpendicular to the second direction, the magnetizing direction of the magnetic steel 112 is perpendicular to the vibration direction of the vibrator assembly 12, and the magnetizing directions of the two magnetic steels 112 are opposite, that is, the magnetic poles of the two magnetic steels 112 are opposite in the direction of the corresponding coil 1222. In this way, a stable magnetic field passing through the coil 1222 can be formed between the two magnetic steels 112. After the coil 1222 is charged, a driving force is generated to drive the vibrator assembly 12 to reciprocate in the second direction.

[0049] Further, referring to FIG. 7 and FIG. 8 , the touch component 13 includes a sensor 131 connected to the side of the vibrator component 12 facing away from the stator component 11 and a button 133 covering the side of the sensor 131 facing away from the vibrator component 12 .

[0050] In this embodiment, the sensor 131 is fixed to the side of the top plate 1211 facing away from the fixing frame 111. Specifically, the sensor 131 is fixed to the top plate 1211 by adhesive. The top plate 1211 is provided with a plurality of through holes. Specifically, the top plate 1211 is provided with two through holes evenly spaced apart. The through holes are used to pass the connecting wires of the sensor 131.

[0051] It should be understood that sensor 131 can be a sheet-like pressure sensor, such as a thin film sensor, preferably a single-point pressure sensor or a multi-point pressure sensor with two or more dimensions. A two-dimensional single-point sensor can detect pressure in a first direction and a second direction, i.e., it can detect both sliding and pressing actions performed by the user on the touch component 13. The magnetic circuit system is designed to provide different vibration frequencies for different actions, further providing different vibration sensations to the user. Preferably, sensor 131 is a flexible thin film sensor that can be applied to different terminal devices, reducing the differences in the use of the touch vibration device 10 on different terminal devices.

[0052] 1 to 3 , an embodiment of the present invention further provides a terminal device, including a housing 20 and a touch-vibration device 10 mounted on the housing 20 , wherein the outer side of the touch component 13 is exposed on the outer surface of the housing 20 .

[0053] In this embodiment, the terminal device is a tablet device. The housing 20 includes a screen 22, a back panel 23 spaced apart from the screen 22, and side frames 21 surrounding the edges of the screen 22 and the back panel 23. The screen 22, back panel 23, and side frames 21 together form a cavity. The touch-vibration device 10 is fixed to the side frames 21, with a first direction extending along the thickness of the side frames 21 and a second direction extending along the length of the side frames 21. When a user presses the touch component 13 on the terminal device, the effect of the driving force on the touch-vibration device 10 in the non-pressing direction is reduced, making it suitable for different types of terminal devices.

[0054] In other embodiments, the terminal device is not limited to a tablet device, but can also be various special-shaped devices such as a handle, a keyboard, a steering wheel, etc. The touch vibration device 10 can be fixed at any position on the terminal device housing 20, as long as the touch vibration device 10 is fixed to the terminal device, the space in the second direction of the touch vibration device 10 is larger than the space in the first direction.

[0055] Further, referring to FIGS. 1 to 3 , the touch component 13 protrudes from the surface of the housing 20 , and the stator component 11 is fixed to the housing 20 .

[0056] In this embodiment, the side frame 21 has a boss 211 protruding into the cavity along the direction in which the thickness extends. The boss 211 is provided with a groove 212 with two open ends along the direction in which the thickness extends. Two mounting protrusions 213 protrude from both ends of the boss 211 toward the cavity along the direction in which the thickness of the side frame 21 extends. The two mounting protrusions 213 are centrally symmetrically arranged, and the two ends of the base plate 1111 are fixedly connected to the two mounting protrusions 213. Specifically, two bosses protrude from both ends of the base plate 1111 toward the two mounting protrusions 213. The two mounting protrusions 213 are provided with two grooves that match the bosses, and each boss is inserted into each groove with an interference fit. In other embodiments, the base plate 1111 can also be screwed or adhesively connected to the mounting protrusions 213.

[0057] The two side plates 1212 of the shell 121 are spaced apart from the inner wall of the groove body 212, reserving space for elastic deformation and displacement of the two side plates 1212 in the second direction, which facilitates the vibration of the shell 121 and enables the touch component 13 fixed on the shell 121 to vibrate with the vibration of the shell 121, thereby providing the user with vibration in the second direction, which is the non-pressing direction, when the user presses the touch component 13 in the first direction.

[0058] It can be seen that compared with the terminal devices in the related art, the stator component 11 and the vibrator component 12 of the touch vibration device 10 in the terminal device in this embodiment are housed in the terminal device, and the touch component 13 protrudes from the surface of the terminal device. The touch component 13 is directly connected to the vibrator component 12. The vibration change experienced by the user is more obvious, the vibration experience is better, and the non-pressing direction is not affected by the force applied in the pressing direction. It can adapt to various different terminal devices.

[0059] The side of the side frame 21 facing away from the cavity is recessed toward the cavity to form a mounting groove 214. The touch assembly 13 also includes a gasket 132 that matches the mounting groove 214 and is fixed in the mounting groove 214. The gasket 132 is square-shaped. The button 133 matches the mounting groove 214. The side of the button 133 facing the cavity is attached to the gasket 132, and the side of the button 133 facing away from the cavity has a protruding pressing portion. Optionally, the gasket 132 is adhesively connected to the mounting groove 214, and the button 133 is adhesively connected to the gasket 132. The gasket 132 is not limited to a square shape and can also be an oval or other shape. The gasket 132 can be a metal gasket 132, a gasket 132 made of silicone or rubber. The gasket 132 is used to fix the button 133, form a partition between the housing 20 and the button 133, and also to protect the button 133.

[0060] Referring to FIG. 9 , an embodiment of the present invention further provides a control method, which is applied to the touch vibration device 10 . The control method includes:

[0061] S100: Detecting pressing information in a first direction through the touch component 13, and calling an effect signal in an effect library of the terminal device according to the pressing information;

[0062] S200: Determine driving parameters according to the effect signal, and generate a vibration signal for driving the vibrator assembly 12 to vibrate according to the driving parameters.

[0063] In this embodiment, step S100 specifically includes:

[0064] S101: Detecting pressing information in a first direction through the touch component 13, where the pressing information includes at least position information and pressure information;

[0065] S102: Calling the effect signal in the effect library of the terminal device according to the position information and the pressure information, where the effect signal at least includes the key 133 effect signal and the sliding key effect signal.

[0066] In this embodiment, step S200 specifically includes:

[0067] S201: Determine driving parameters according to the key 133 effect signal and the slide key effect signal;

[0068] S202: Generate a vibration signal for driving the vibrator assembly 12 to vibrate according to the driving parameters.

[0069] The above description is only an embodiment of the present invention. It should be pointed out that those skilled in the art can make improvements without departing from the creative concept of the present invention, but these improvements all fall within the scope of protection of the present invention.
