Technical Field

[0001] The present invention belongs to the technical field of micro motors, and in particular relates to an XYZ three-directional vibrator. Background Art

[0002] With the rapid development of portable and intelligent electronic products, consumers prefer electronic products with the best tactile experience, such as smart phones, handheld game consoles, medical and health equipment, multimedia entertainment equipment, etc. These electronic products generally use vibration motors for vibration feedback, such as the vibration reminder of incoming calls on mobile phones, the vibration feedback of game consoles, the vibration of vibrating toothbrushes used in medical and health care, etc.

[0003] However, most existing vibration motors offer unidirectional vibration, vibrating in a single direction. While there are also related technologies for linear vibration motors that can vibrate in two directions, there are few XYZ tri-directional vibrators that can vibrate in all three directions simultaneously and independently, and thus cannot provide users with the multi-dimensional tactile feedback they desire. Summary of the Invention

[0004] The purpose of the present invention is to provide an XYZ three-directional vibrator that can adapt to a monopole magnet and a circuit structure to satisfy the user's vibration experience of multi-dimensional tactile feedback.

[0005] To achieve the above object, the technical solution adopted by the present invention is as follows:

[0006] The XYZ three-directional vibrator includes a casing, a base, a vibrator assembly and a stator assembly. The casing and the base are combined to form a accommodating space. The vibrator assembly includes an XY direction vibrating block and a Z direction vibrating block. The stator assembly includes a coil and a flexible circuit board. The XY direction vibrating block and the Z direction vibrating block are respectively fixed and suspended in the accommodating space by elastic parts. A circular hole is set in the middle of the XY direction vibrating block, and the circular hole surrounds the Z direction vibrating block. The XY direction vibrating block is inlaid with a first magnet assembly and a second magnet assembly. The first magnet assembly and the second magnet assembly are respectively symmetrically structured with the circular hole as the center. The first magnet assembly and the second magnet assembly are respectively provided with coils in the direction of the base.

[0007] Furthermore, the XY direction vibration block is a rectangular parallelepiped, the first magnet assembly is embedded in parallel at both ends of the short side of the XY direction vibration block, and the second magnet assembly is embedded in the middle of the first magnet assembly.

[0008] Furthermore, the first magnet assembly and the second magnet assembly are monopole magnets.

[0009] Furthermore, the first magnet assembly is two groups of monopole magnets, and the second magnet assembly is one group of monopole magnets. Each group of magnets consists of two magnets with N poles and S poles and corresponds to one coil.

[0010] Furthermore, the number of the first magnet assembly and the number of the second magnet assembly are 2 respectively.

[0011] Furthermore, the first magnet assembly corresponds to two X-direction coils connected in series, and the second magnet assembly corresponds to one Y-direction coil, and the Y-direction coil surrounds the outer circumference of the circular hole.

[0012] Furthermore, the second magnet assembly corresponds to two Y-direction coils connected in series, and the Y-direction coils are arranged on both sides of the circular hole.

[0013] Furthermore, the flexible circuit board includes an inner ring connected to the Z-direction coil and an outer ring connected to the XY-direction coil. The inner ring is a hollow circular surface, and the inner ring circular surface is arranged parallel to the outer ring plane and spaced apart.

[0017] 1. The XYZ three-directional vibrator provided by the present invention can vibrate in the X, Y, and Z directions simultaneously, and can vibrate in the XY, XZ, YZ, or XYZ directions simultaneously.

[0045] The present invention will be further described in detail below with reference to the accompanying drawings.

[0046] See also Figures 1 to 17 The XYZ three-directional vibrator includes a housing 1, a base 18, a vibrator assembly (not shown), and a stator assembly (not shown). The open end of the housing 1 is fixed to the base 18. The housing 1 and the base 18 form a storage space to protect the internal components and also serve as a vibration carrier. Figure 2 The housing 1 is made of stainless steel. A square step 104 is provided on the top of the housing 1, which is recessed into the receiving space. The square step 104 is used to fix the elastic member. A circular boss 103 is provided in the center of the square step 104, facing the opposite direction of the receiving space. The circular boss 103 provides and limits the effective vibration space for Z-direction vibration.

Figure 15 The base 18 is a stainless steel plate, and a circular sink 1803 is provided in the middle of the base 18. The circular sink 1803 provides and limits the effective vibration space for Z-direction vibration. A square groove 1802 is provided on the periphery of the circular sink 1803 near the signal source groove 101, and a noise reduction hole 1804 is provided in the center of the circular sink 1803.

[0047] See also Figure 1 The vibrator assembly of the XYZ three-directional vibrator includes two vibrating blocks, namely the XY direction vibrating block 11 and the Z direction vibrating block 3, and the stator assembly includes a coil and a flexible circuit board 17; the XY direction vibrating block 11 and the Z direction vibrating block 3 are respectively fixed and suspended in the accommodation space by elastic parts, and a circular hole 1103 is set in the middle of the XY direction vibrating block 11, and the circular hole 1103 surrounds the Z direction vibrating block 3. The Z direction vibrating block 3 always moves inside the circular hole 1103 of the XY direction vibrating block.

[0048] The XY direction vibration block is inlaid with a first magnet assembly (not marked) and a second magnet assembly (not marked). The first magnet assembly and the second magnet assembly are symmetrically structured with the circular hole 1103 as the center. The first magnet assembly and the second magnet assembly are provided with coils in the direction of the corresponding base 18; the Z direction vibration block 3 is provided with a cylindrical magnetic shell 4 with one end open, and the bottom of the Z direction vibration block is provided with a magnetic shell 4. A cylindrical Z direction driving magnet 5 is fixed at the center position of the inner surface of the top wall of the magnetic shell 4, that is, the Z direction driving magnet 5 is fixed inside the magnetic shell. A gap is formed between the magnetic shell 4 and the Z direction driving magnet 5, and a circular coil is provided in the gap. The width of the gap is greater than the thickness of the coil, so that the coil can move relative to each other in the gap without interference. When the Z direction coil 7 is energized, the Lorentz force is used to push and pull the Z direction vibration block 3 back and forth, converting electrical energy into mechanical energy, and the whole constitutes a Z direction driving structure. The coil is fixed to and electrically connected to a flexible printed circuit board (FPCB) 17, also known as an FPCB (Flexible Printed Circuit Board). The flexible circuit board 17 is mounted on a base 18. The XYZ tri-directional vibrator provided by the present invention can vibrate simultaneously in the X, Y, and Z directions, as well as in the XY, XZ, YZ, or XYZ directions simultaneously. This tri-directional vibrator provides vibration feedback in three dimensions, significantly enhancing the vibration feedback effect and providing users with a multi-dimensional tactile feedback experience.

[0049] See also Figures 7 to 14 The XY direction vibration block 11 is a rectangular parallelepiped and is provided with a driving magnet placement hole. The first magnet assembly is parallelly embedded at both ends of the short side of the XY direction vibration block 11, and the second magnet assembly is parallelly embedded in the middle of the first magnet assembly of the XY direction vibration block 11. The first magnet assembly includes X-direction driving magnets 13a~13d, and the second magnet assembly includes Y-direction driving magnets 12a~12b. The bar magnets 13a~13d are fixed in the X-direction driving magnet placement holes 1101a~1101d at both ends of the XY direction vibration block 11, and the bar magnets 12a~12b are fixed in the Y-direction driving magnet placement holes 1105a~1105b in the middle position of the XY direction vibration block 11. The first and second magnet assemblies are monopole magnets, with an innovative monopole magnet structure designed in the horizontal direction. The magnets correspond to the two opposite sides of the square coil respectively, and the overall combined force provides horizontal drive, so that the X, Y, and Z directions are all separate coils, thereby enabling the XYZ three-directional vibrator to meet unidirectional motion. According to the first embodiment of this case, please refer to Figure 12The first magnet assembly consists of two sets of monopole magnets, and the second magnet assembly consists of one set of monopole magnets. 13a-13b form one set of the first magnet assembly, and 13c-13d form another set of the first magnet assembly. The two sets of first magnet assemblies are symmetrically arranged around circular hole 1103, with the north and south poles of the two sets of magnets facing each other. The second magnet assembly consists of one set of magnets, 12a-12b, each set of magnets consisting of two magnets with north and south poles and corresponding to one coil. The first magnet assembly corresponds to two series-connected X-direction coils 15a-15b, while the second magnet assembly corresponds to one Y-direction coil. Y-direction coil 16 surrounds the outer circumference of the circular hole.

[0050] According to the second embodiment of this case, please refer to Figure 13 The first and second magnet assemblies are each composed of two groups, with 13a-13b forming one group and 13c-13d forming another group. The two groups are symmetrically arranged around the circular hole 1103. Each group of magnets in the first magnet assembly consists of two magnets with north and south poles, corresponding to one coil. The second magnet assembly is composed of one group, 12a-12b, with each magnet with north and south poles corresponding to one coil. The second magnet assembly corresponds to two Y-direction coils 16a-16b connected in series, with the Y-direction coils arranged on both sides of the circular hole.

[0051] According to the third embodiment of this case, please refer to Figure 14 The first and second magnet assemblies are each composed of two groups, with 13a-13b forming one group and 13c-13d forming another group. The two groups are symmetrically arranged around the circular hole 1103. Each group of magnets in the first magnet assembly consists of two magnets with north and south poles and corresponds to one coil. The second magnet assembly is composed of one group, 12a-12b, with each group of magnets consisting of two magnets with north and south poles and corresponding to one coil. The second magnet assembly corresponds to two Y-direction coils 16a-16b connected in series, which are arranged on both sides of the circular hole.

[0052] See also Figures 11 to 15The flexible circuit board 17 is mounted on the base 18 and includes an inner ring electrically connected to the Z-direction coil and an outer ring connected to the XY-direction coil. The inner ring is a hollow circular surface, parallel to the outer ring plane and spaced apart. The inner and outer rings of the flexible circuit board 17 are electrically connected via a connecting bridge 1704. The hollow circular surface is an inner ring 1705 located in the center of the flexible circuit board 17. The shape of the hollow circular surface inner ring 1705 corresponds to the circular depression 1803. The hollow circular surface inner ring 1705 is pressed into the bottom of the circular depression 1803 of the base and fixed. The outer ring is directly mounted on the surface of the base. The flexible circuit board 17 has a protruding external power supply terminal (not shown). The external power supply terminal extends through the signal source groove 101 of the housing 1 to connect to the external power supply. The external power supply terminal is equipped with six signal source interfaces 1701a, 1701b, 1702a, 1702b, 1703a, and 1703b. 1701a and 1701b are the X-direction coil current inputs; 1703a and 1703b are the Y-direction coil current inputs; and 1702a and 1702b are the Z-direction coil current inputs. The square groove 1802 on the base 18 is used to avoid the connection bridge. The side of the square groove 1802 corresponding to the signal source interface can also be used for foolproofing.

[0053] In the first embodiment of this invention, a cylindrical Z-direction coil 7 is fixed to the inner circumference of a flexible circuit board 17. A Y-direction coil 16 is fixed to its outer circumference. The Y-direction coil 16 is a large rectangular coil. X-direction coils 15a and 15b are fixed to the short ends of the Y-direction coil 16. The X-direction coils are two small rectangular coils 15a and 15b. The flexible circuit board 17 includes X-direction signal source interfaces, Z-direction signal source interfaces, and Y-direction signal source interfaces. The X-direction signal source interface connects to the X-direction coil, the Y-direction signal source interface connects to the Y-direction coil, and the Z-direction signal source interface connects to the Z-direction coil. The Z-direction coil 7 provides Z-direction drive, corresponding to signal sources 1702a-1702b. The small rectangular coils 15a and 15b are connected in series and connected to signal ports 1701a-1701b, providing X-direction drive. The large rectangular coil provides Y-direction drive, corresponding to signal sources 1703a-1703b. The Z-direction coil 7 is welded to the hollow circular surface in the middle of the flexible circuit board. The electrical connection pattern of the flexible circuit board is connected to the hollow circular surface in the middle with a connecting bridge. This structure makes it easy to bend the circular surface part welded with the Z-direction coil and fit it to the end face of the circular sink 1803 of the vibrator base, so that the Z-direction coil is facing the Z-direction driving magnet, generating a Z-direction electromagnetic force when powered. At the same time, it provides an effective vibration space for the Z-direction vibration component to vibrate downward. The magnet and the coil group correspond to each other. When the current model passes through the coil, a Lorentz force is formed between the two, which in turn drives the XY-direction vibration block to move and complete the vibration action. A circular hole 1103 is provided in the middle of the XY-direction vibration block. The circular hole 1103 is used to avoid the space required for Z-direction vibration. The Y-direction coil is surrounded by the circular hole.

[0054] See also Figures 7 to 11 The XY-direction vibration block 11 is fixed and suspended in the accommodation space by an S-shaped spring 13. One end of the S-shaped spring 13 is fixed to the short side of the XY-direction vibration block 11, and the other end of the S-shaped spring 13 is fixed to the inner wall of the side of the casing 1. The XY-direction vibration block 11 is fixed by two S-shaped springs 13 so that it is suspended between the casing and the base. The S-shaped spring 13 is connected to the inner side of the XY-direction vibration block and fixed by laser welding. The outer side of the S-shaped spring is fixed to the inner wall 102 of the casing, and the two S-shaped springs 13 pull the XY-direction vibration block 11, allowing the XY-direction vibration block to be suspended in the middle.

[0055] See also Figure 9 The S-shaped spring 14 is a thin plate structure made of stainless steel. It includes a first straight edge 1401, a second arc 1402, a third arc 1403, a fourth straight edge 1404, and a fifth straight edge 1405. The first straight edge 1401 is fixed to the short side of the XY-axis vibration block 11. The second and third arcs 1402 and 1403 form an S-shaped structure, which acts as a vibration buffer in opposite directions. The fourth straight edge 1404 is the primary elastic structure and energy transmission mechanism. The fifth straight edge 1405 is fixed to the inner wall of the housing 1. The S-shaped spring 13 suspends the XY-direction vibration block 11 as a whole between the housing and the base. A rectangular groove 1102 is opened on the side of the long side of the XY-direction vibration block to avoid the S-shaped spring 14. The rectangular groove 1102 is used to avoid the S-shaped springs 14a~14b. The horizontal vibration block is made of tungsten alloy. The first straight edge 1401 is welded to the wall of the groove 1102, and the fifth straight edge 1405 is welded to the inner wall of the housing 1 on the short side of the XY-direction vibration block 11.

[0056] See also Figure 1 and Figure 7 An XY direction magnetic isolation plate 9 is fixed on the upper end of the XY direction vibration block 11. The XY direction magnetic isolation plate 9 is used to optimize the magnetic circuit. The XY direction magnetic isolation plate 9 is fixed as a whole on the upper end of the horizontal vibration block to shield the multi-level magnet magnetic circuit and optimize the magnetic circuit.

[0057] A noise-reducing and anti-collision foam 10 is fixed on the upper end of the XY direction vibration block 11. The noise-reducing and anti-collision foam 10 is annular and fixed in the annular step 1104 at the upper end of the horizontal vibration block. The noise-reducing and anti-collision foam 10 effectively prevents the XY direction vibration block 11 and the Z direction vibration block 3 from colliding and causing noise.

[0058] See also Figures 3 to 6The Z-direction vibration block 3 is fixed and suspended in the accommodation space by two upper and lower springs. The upper end surface 304 of the Z-direction vibration block is fixed to the inner ring 202 of the first spring, and the outer ring 201 of the first spring is fixed to the inner wall of the casing. The lower end surface 303 of the Z-direction vibration block is fixed to the inner ring 802 of the second spring, and the outer ring 801 of the second spring is fixed in the circular sink 1803 of the base 18, that is, the outer ring of the lower spring is fixedly connected to the boss of the base. The upper and lower springs provide support for the Z-direction vibration block and keep it vertical, thereby providing the necessary conditions for Z-direction resonance.

[0059] The first Z-direction spring 2 and the second Z-direction spring 8 form a vertical vibration elastic force combination. In this embodiment, the spring wire of the first Z-direction spring 2 is counterclockwise distributed, and the spring wire of the second Z-direction spring 8 is clockwise distributed. The extension direction of the spring wires of the first spring and the second spring is opposite. It can also be adjusted so that the spring wire of the first Z-direction spring is clockwise distributed and the spring wire of the second Z-direction spring is counterclockwise distributed. Figure 3 As shown, three first spring wires 203 are provided between the first spring inner ring 202 and the first spring outer ring 201 in the Z direction. The three first spring wires 203 are evenly distributed in a spiral pattern to provide a Z-direction elastic force structure. Figure 6 As shown, three second spring wires 803a to 803c are provided between the inner ring 802 and the outer ring 801 of the second spring in the Z direction. The three spring wires are evenly distributed in a spiral to provide a Z-direction elastic structure.

[0060] Referring to Figure 4 , the Z-direction vibration block 3 is provided with air escape holes. In this embodiment, three air escape holes 301a to 301c are provided. A groove, namely, the Z-direction vibration block groove 302, is provided at the bottom of the Z-direction vibration block 3. The Z-direction vibration block groove 302 is used to fix the magnetic conductive housing 4. When the Z-direction vibration block is in operation, the air escape hole 301 facilitates the passage of internal compressed air. A stepped portion (not shown) is provided on the edge of the upper end surface 304 of the Z-direction vibration block, which is fixed to the inner ring of the first Z-direction spring. A groove, namely, the Z-direction vibration block magnetic fluid groove 305, is provided at the center of the upper end surface 304 of the Z-direction vibration block. The Z-direction vibration block magnetic fluid groove 305 is used to store magnetic fluid and reduce noise. The lower end surface 303 of the Z-direction vibration block is fixed to the inner ring 802 of the second Z-direction spring. The Z-direction vibration block subsequently moves between the first Z-direction spring and the second Z-direction spring.

[0061] See also Figure 5 The magnetic housing 4 is embedded in the Z-direction vibration block groove 302. A Z-direction driving magnet 5 is fixed inside the magnetic housing 4. A Z-direction magnetic leakage shield 6 is bonded to the end face of the Z-direction driving magnet 5. Together, the three components form the effective magnetic field required for Z-direction vibration. Both the magnetic housing 4 and the Z-direction magnetic leakage shield 6 correct the magnet's magnetic circuit, strengthening the internal magnetic field and reducing external magnetic field divergence. The Z-direction coil 7 is a cylindrical Z-direction coil, with its bottom end fixed to the FPCB.

[0062] The Z-direction vibration block has a T-shaped structure. The upper circular surface of the vibration block is provided with a circular sunken groove, which is used to place magnetic fluid and has a damping and noise reduction effect when colliding with the outer shell. A circular shallow groove is provided on the upper circular edge of the balance block, which is used to place and fix the inner ring of the first spring in the Z direction. The Z-direction vibration block is provided with a ladder-shaped table at the bottom, which is used to place and fix the inner ring of the second spring in the Z direction, so that the first and second springs in the Z direction and the vibration block are connected as one and provide support for them. The lower part of the vibration block is provided with an inwardly concave cylindrical inner cavity, which is used to place and fix the cylindrical magnetic conductive shell. The magnetic conductive shell has a built-in Z-direction drive magnet. The end face of the Z-direction drive magnet is provided with a magnetic leakage prevention sheet.

[0063] See also Figure 16 The XYZ vibrator is a rectangular parallelepiped with a circular sink at the base, providing effective downward forced vibration space for the Z-direction vibrating block. This also facilitates the secure fit of the hollowed-out circular surface of the FPCB, where the Z-direction coil is welded, to the sink. The vibrator's base's upper perimeter is used to connect and secure the outer ring of the second Z-direction spring. This supports the Z-direction vibrating block and maintains its vertical position, while also creating the necessary conditions for the Z-direction spring's elastic recovery. Figure 17 , along the cross-sectional view of section line A, the outer ring of the lower spring is fixedly connected to the boss of the base, that is, the outer ring of the second spring 801 is fixed on the inward concave boss of the circular sink 1803 of the base 18. A noise reduction hole is designed in the center of the circular sink of the base, which is used to reduce the interference of air resistance on the Z-direction vibration component during vibration.
