[0002] Modern electronic devices (such as mobile phones and tablets) typically include haptic feedback mechanisms that generate vibrations in response to user actions. Many traditional haptic feedback mechanisms utilize eccentric rotating mass (ERM) motors. However, because these mechanisms generate vibrations through the rotation of an eccentric mass (rotor), they are not conducive to miniaturization and are difficult to control precisely.

[0100] Activity section 100 has an upper part 150 and a lower part 160, in Figure 1 You can see the upper part 150 of the activity section 100, and the lower part 160 of the activity section. Figure 1 It is not visible from that perspective. The outer shell 210 of the fixing part 200 has a top surface 215, a first sidewall 211, a second sidewall 212, a third sidewall 213, and a fourth sidewall 214, from... Figure 1 The top surface 215, the second sidewall 212, and the third sidewall 213 of the outer casing 210 can be seen.

[0101] The housing 210 and base 220 of the fixed part 200 can be combined to form a space to accommodate a component located inside the fixed part 200. The drive assembly 300 can drive the movable part 100 to vibrate relative to the fixed part 200 in the direction of the first axis D1. The connecting assembly 400A is flexible. The movable part 100 is movably connected to the fixed part 200 via the connecting assembly 400A.

[0102] The magnetic component 320 of the drive assembly 300 corresponds to the coil 310. A magnetically conductive element 330 is fixedly disposed on the magnetic component 320 and has a magnetically conductive material. The magnetically conductive element 330 is used to adjust the magnetic field distribution generated by the magnetic component 320. The coil 310 and the magnetic component 320 are arranged along the direction of the main axis D3. When viewed along a direction perpendicular to the main axis D3 (e.g., the first axis D1 or the second axis D2), the movable part 100 at least partially overlaps with the coil 310. This arrangement allows the haptic feedback mechanism 10 to reduce its thickness in the direction of the main axis D3, thereby achieving miniaturization.

[0103] Figure 2A A perspective view showing a portion of a haptic feedback mechanism 10 according to some embodiments of the present disclosure is shown, including a lower portion 160 of the movable part 100, a second sidewall 212 and a third sidewall 213 of the housing 210, a magnetic assembly 320, and a connecting assembly 400A.

[0106] The movable part 100 and the connecting component 400A are made of different metal materials. The density of the metal material used in the connecting component 400A is lower than that of the metal material in the movable part 100. For example, the connecting component 400A may be made of a copper alloy, while the movable part 100 may be made of tungsten. This configuration can increase the vibration intensity of the movable part 100, thereby improving the performance of the haptic feedback mechanism 10.

[0107] The first movable part fixing end 410A, the second movable part fixing end 415A, and the first fixed part fixing end 420A have an integrally formed structure.

[0123] The first fixing end 420B and the second fixing end 425B are disposed on the first side wall 211 of the housing 210. The first movable part fixing end 410B, the first fixing end 420B, and the second fixing end 425B have a plate-like structure. The first movable part fixing end 410B is located between the movable part 100 and the first side wall 211.

[0124] When viewed along the main axis D3, the first elastic portion 430B and the second elastic portion 435B are conical in shape, and are mirror-symmetrical with respect to the movable portion 100. This design, which folds the connecting component 400B within the limited space of the haptic feedback mechanism 10, allows the connecting component 400B in this embodiment to have a smaller elastic coefficient, thereby increasing the vibration intensity of the haptic feedback mechanism 10 and improving its performance.

[0125] Figure 4B The second stop 120 of the shown embodiment is at the second extreme position at the same as Figure 3C to Figure 3D The second stop 120 operates in a manner that... That is, when... Figure 4BActivity Department 100 in such Figure 3C to Figure 3D When the second limit position is displayed, the second stop 120 can be as follows: Figure 3C The direct contact shown is with the second sidewall 212, or as... Figure 3D The second buffer element 620 shown is indirectly in contact with the second sidewall 212 by being provided on the second stop 120 or the second sidewall 212, so as to limit the range of motion of the movable part 100.

[0126] According to some embodiments of this disclosure Figures 5A to 5B show Figure 4B The image shows a partial front view of the movable part 100 within box D in the image, positioned at its first extreme position. When the movable part 100 is in the first extreme position, the fixed end 410B of the first movable part restricts the movable part 100 relative to the fixed part 200. Figure 1 The range of motion of ). For example Figures 5A to 5B As shown, in the first extreme position, the first movable part fixed end 410B can directly or indirectly contact the first fixed part fixed end 420B and the second fixed part fixed end 425B.

[0127] exist Figure 5A In the illustrated embodiment, the first movable part fixed end 410B directly contacts the first fixed part fixed end 420B and the second fixed part fixed end 425B at the first extreme position. Figure 5B In the illustrated embodiment, the haptic feedback mechanism 10 further includes a first buffer element 610B. The first buffer element 610B is made of plastic material and can be disposed on the first movable part fixed end 410B or on both the first fixed part fixed end 420B and the second fixed part fixed end 425B. When the movable part 100 is in the first extreme position, the first movable part fixed end 410B indirectly contacts the first fixed part fixed end 420B and the second fixed part fixed end 425B through the first buffer element 610B.

[0128] According to some embodiments of this disclosure Figure 6A A perspective view showing the movable part 100, magnetic component 320, connecting component 400B, and adjustment element 700 of the haptic feedback mechanism 10. Figure 6A In the illustrated embodiment, the adjustment element 700 is disposed on the first elastic portion 430B and the second elastic portion 435B of the connecting assembly 400B.

[0129] like Figure 6AAs shown, the adjustment element 700 has a plate-like structure. The Young's modulus of the adjustment element 700 is greater than that of the first elastic portion 430B and the second elastic portion 435B. The adjustment element 700 can be used to adjust the elastic coefficients of the first elastic portion 430B and the second elastic portion 435B to change the vibration intensity and vibration frequency of the haptic feedback mechanism 10. The adjustment element 700 and the connecting assembly 400B are made of different metal materials, such as different copper alloys.

[0130] According to some embodiments of this disclosure Figure 6B A perspective view showing the active part 100, the magnetic component 320, and the connecting component 400B. Figure 6B In the illustrated embodiment, both the first elastic portion 430B and the second elastic portion 435B have a first opening 431 and a second opening 432, respectively. The first opening 431 and the second opening 432 are independent structures formed on the first elastic portion 430B and the second elastic portion 435B. That is, both the first elastic portion 430B and the second elastic portion 435B have a first opening 431 and a second opening 432, and the structure of the first opening 431 is not affected by the structure of the second opening 432, and vice versa. This arrangement reduces the elastic coefficient of the connecting component 400B, thereby increasing the vibration intensity of the haptic feedback mechanism 10 and improving its performance.

[0131] According to some embodiments of this disclosure Figure 6C A perspective view showing the active part 100, the magnetic component 320, and the connecting component 400B. Figure 6C In the shown embodiment, the movable part 100 includes two third stop parts 130, and the first elastic part 430B and the second elastic part 435B each have a first opening 431 and a second opening 432, respectively.

[0132] like Figure 6C As shown, the third stop 130 is a protruding structure on the two surfaces of the movable part 100 near the third side wall 213 (not shown) and the fourth side wall 214 (not shown). The first opening 431 and the second opening 432 are as follows... Figure 6B The first elastic portion 430B and the second elastic portion 435B are shown. The two third stop portions 130 pass through the first opening 431 and the second opening 432 on the first elastic portion 430B and the second elastic portion 435B, respectively.

[0133] This configuration not only reduces the elastic coefficient of the connecting component 400B, but also increases the mass of the moving part 100, thereby increasing the vibration intensity and maximum acceleration of the haptic feedback mechanism 10 and improving the performance of the haptic feedback mechanism 10.

[0134] According to some embodiments of this disclosure Figures 7A to 7B show Figure 6C The image shows a partial front view of the movable part 100 within box E in its third extreme position. When the movable part 100 is in the third extreme position, the third stop 130 restricts the range of motion of the movable part 100 relative to the fixed part 200 (not shown). Figures 7A to 7B As shown, in the third extreme position, the third stop 130 can directly or indirectly contact the third sidewall 213 of the housing 210.

[0135] exist Figure 7A In the illustrated embodiment, the third stop 130 directly contacts the third sidewall 213 at the third extreme position. Figure 7B The illustrated embodiment also includes a third buffer element 630. The third buffer element 630 is made of plastic material and can be disposed on the third stop portion 130 or the third sidewall 213. When the movable portion 100 is in the third extreme position, the third stop portion 130 indirectly contacts the third sidewall 213 through the third buffer element 630.

[0136] According to some embodiments of this disclosure, another third stop 130 (not shown) near the fourth sidewall 214 (not shown) may also contact the fourth sidewall 214 directly or indirectly through another buffer element at a fourth extreme position in a similar manner as described above.

[0137] Reference Figure 8A The magnetic component 320 disclosed herein can also be a Halbach array. Figure 8A The exploded view shows the lower part 160 of the movable section 100 and the magnetic component 320. In this embodiment, the magnetic component 320 includes a first magnetic element 321, a second magnetic element 322, a third magnetic element 323, a fourth magnetic element 324, and a fifth magnetic element 325. The arrangement of the magnetic components 320 in the Heilbeck array will be described in detail below.

[0138] Figure 8B show Figure 8A A cross-sectional view along line F shows the movable part 100 and the magnetic component 320. The arrangement of the Hellbeck array will be illustrated below using the first magnetic element 321, the second magnetic element 322, the third magnetic element 323, and the fourth magnetic element 324 as examples. The first magnetic element 321 has a first pole pair including an N pole and a S pole. The second magnetic element 322 has a second pole pair including an N pole and a S pole. The third magnetic element 323 has a third pole pair including an N pole and a S pole. The fourth magnetic element 324 has a fourth pole pair including an N pole and a S pole.

[0139] The first, second, third, and fourth magnetic pole pairs are arranged in different orientations. The poles of the second and third magnetic pole pairs are aligned along the first axis D1, while the poles of the first and fourth magnetic pole pairs are aligned along the principal axis D3.

[0140] The N pole of the second magnetic pole pair is closer to the first magnetic element 321 than the S pole of the second magnetic pole pair. The N pole of the third magnetic pole pair is closer to the first magnetic element 321 than the S pole of the third magnetic pole pair. The S pole of the first magnetic pole pair is closer to the magnetically conductive element 330 than the N pole of the first magnetic pole pair, and the N pole of the first magnetic pole pair is closer to the recess 165 that accommodates the coil 310 than the S pole of the first magnetic pole pair. The S pole of the fourth magnetic pole pair is closer to the recess 165 that accommodates the coil 310 than the N pole of the fourth magnetic pole pair, and the N pole of the fourth magnetic pole pair is closer to the magnetically conductive element 330 than the S pole of the fourth magnetic pole pair.

[0141] With this configuration, the magnetic field of the magnetic component 320 on the side of the recess 165 that accommodates the coil 310 can be significantly enhanced, and the resulting magnetic field is as follows: Figure 8B As indicated by the arrow near the recess 165. This configuration reduces the number of coils required, achieving miniaturization, and allows for the generation of a stronger magnetic field than a typical magnetic component 320 with fewer magnetic elements, thus improving performance.

[0142] According to some embodiments of this disclosure Figure 9 A cross-sectional side view of the haptic feedback mechanism 10 is shown. The movable part 100, housing 210, base 220, coil 310, magnetic assembly 320, printed circuit board 340, and connecting assembly 400 can be seen. In some embodiments, the haptic feedback mechanism 10 may have a damping element 500 in a non-motion axis (e.g., the direction of the spindle D3 in this embodiment). The damping element 500 may be as follows: Figure 9 The position shown is between the movable part 100 and the fixed part 200. The addition of the damping element 500 can adjust the motion parameters of the haptic feedback mechanism 10, thereby increasing the stability of the device disclosed herein and reducing noise.

[0143] This disclosure provides a haptic feedback mechanism in which a movable part is movably connected to a fixed part via a connecting component, and a driving component drives the movable part to move relative to the fixed part to achieve vibration. This disclosure achieves miniaturization and ease of assembly through different configurations of the movable part and the connecting component. Furthermore, by changing the elastic coefficient of the connecting component and increasing the mass of the movable part, this disclosure improves the vibration intensity and maximum acceleration of the haptic feedback mechanism, thereby enhancing its stability and performance.
