[0002] With the advancement of technology, many electronic devices (such as tablets and smartphones) now have tactile feedback capabilities. Tactile feedback mechanisms installed on electronic devices generate vibrations when a user touches the device, providing tactile feedback to the user. For example, when a user presses a button or screen on an electronic device, the tactile feedback mechanism can provide tactile feedback.

In fact, a certain number of tactile feedback mechanisms 100 can be installed within the electronic device 1 according to needs.

[0066] See also Figure 2 and Figure 3 . Figure 2 is a schematic diagram of a tactile feedback mechanism 100 according to some embodiments of the present disclosure, and Figure 3FIG is an exploded view of a tactile feedback mechanism 100 according to some embodiments of the present disclosure. Figure 2 Figure 3 As shown, the tactile feedback mechanism 100 may include a fixed portion 10 , a movable portion 20 , a driving component 30 , an elastic component 40 and a connecting element 50 .

[0067] The fixed portion 10 may include a first frame 11, a first cover 12, a second frame 13, and a second cover 14. The movable portion 20 may include a first counterweight element 21. The driving assembly 30 may include a first piezoelectric element 31. The elastic assembly 40 may include a first elastic element 41 and a second elastic element 42. According to some embodiments of the present disclosure, the driving assembly 30 may drive the movable portion 20 to move relative to the fixed portion 10 along a first axis AX1.

[0068] See also Figure 2 According to some embodiments of the present disclosure, the first frame body 11 may include four first frame body walls 111, and the second frame body 13 may include four second frame body walls 131. The first frame body walls 111 may extend toward the second frame body 13, and the second frame body walls 131 may extend toward the first frame body 11. The first frame body walls 111 and the second frame body walls 131 may contact each other and be fixedly connected to each other. In this way, the movable portion 20 can be protected from impact by external elements.

[0069] like Figure 2 As shown, the first frame 11 has a first surface 11a. The first surface 11a can form a first accommodating space 11b. The first cover 12 is disposed on the first frame 11. The first cover 12 can be fixedly connected to the first frame 11, and the first cover 12 can have a second surface 12a. According to some embodiments of the present disclosure, the first surface 11a is located on the first frame 11, the first surface 11a can be annular, and the first surface 11a can be parallel to the first axis AX1. According to some embodiments of the present disclosure, the second surface 12a is located on the first cover 12, and the second surface 12a faces the movable portion 20.

[0070] According to some embodiments of the present disclosure, the first cover 12 can shield the first accommodating space 11b, making the first accommodating space 11b a semi-enclosed space. In other words, the first accommodating space 11b can be formed by the first surface 11a and the second surface 12a.

[0071] Moreover, the first receiving space 11b may correspond to the movable portion 20. That is, according to some embodiments of the present disclosure, when viewed along the first axis AX1, the first receiving space 11b at least partially overlaps with the movable portion 20.

[0072] Please continue reading Figure 2According to some embodiments of the present disclosure, the first accommodating space 11b is open toward the movable portion 20, so that when the movable portion 20 is located at a first extreme position (not shown) relative to the fixed portion 10, the movable portion 20 is at least partially located in the first accommodating space 11b.

[0073] It should be noted that the first extreme position refers to the position where the movable portion 20 is closest to the first cover 12 after the movable portion 20 moves along the first axis AX1. In other words, according to some embodiments of the present disclosure, when the movable portion 20 is at the first extreme position, when viewed along a second axis AX2 perpendicular to the first axis AX1, the movable portion 20 at least partially overlaps with the first surface 11a of the first frame 11.

[0074] The above configuration can increase the range of motion of the movable portion 20, thereby increasing the vibration feedback of the tactile feedback mechanism 100. Moreover, the above configuration can also reduce the size of the tactile feedback mechanism 100, thereby achieving a miniaturized effect.

[0075] like Figure 2 As shown, the second frame 13 has a third surface 13a. The third surface 13a can form a second accommodating space 13b. The second cover 14 is disposed on the second frame 13. The second cover 14 can be fixedly connected to the second frame 13, and the second cover 14 can have a fourth surface 14a. According to some embodiments of the present disclosure, the third surface 13a is located on the second frame 13, the third surface 13a can be annular, and the third surface 13a is parallel to the first axis AX1. According to some embodiments of the present disclosure, the fourth surface 14a is located on the second cover 14, and the fourth surface 14a faces the movable portion 20.

[0076] According to some embodiments of the present disclosure, the second cover 14 can shield the second accommodating space 13b, making the second accommodating space 13b a semi-enclosed space. In other words, the second accommodating space 13b can be formed by the third surface 13a and the fourth surface 14a.

[0077] Moreover, the second receiving space 13b may correspond to the movable portion 20. That is, according to some embodiments of the present disclosure, when viewed along the first axis AX1, the second receiving space 13b at least partially overlaps with the movable portion 20.

[0078] Please continue reading Figure 2 According to some embodiments of the present disclosure, the second accommodating space 13b is open toward the movable portion 20, so that when the movable portion 20 is located at a second extreme position (not shown) relative to the fixed portion 10, the movable portion 20 is at least partially located in the second accommodating space 13b.

[0079] It should be noted that the second extreme position refers to the position where the movable portion 20 is closest to the second cover 14 after the movable portion 20 moves along the first axis AX1. In other words, according to some embodiments of the present disclosure, when the movable portion 20 is at the second extreme position, when viewed along the second axis AX2, the movable portion 20 at least partially overlaps with the third surface 13a of the second frame 13.

[0080] The above configuration can increase the range of motion of the movable portion 20, thereby increasing the vibration feedback of the tactile feedback mechanism 100, thereby achieving an increased vibration effect. Moreover, the above configuration can also reduce the size of the tactile feedback mechanism 100, thereby achieving a miniaturized effect.

[0081] See also Figure 2 According to some embodiments of the present disclosure, the first piezoelectric element 31 is disposed on the movable portion 20. According to some embodiments of the present disclosure, the first weight element 21 of the movable portion 20 can be fixedly connected to at least the first piezoelectric element 31 via a connecting element 50. It should be noted that the first weight element can be made of metal, and the connecting element 50 can be made of glue or solder.

[0082] According to some embodiments of the present disclosure, on the first axis AX1, the maximum size of the first accommodating space 11 b and the maximum size of the second accommodating space 13 b may be the same, so that the tactile feedback mechanism 100 has uniform vibration feedback.

[0083] It should be noted that according to some embodiments of the present disclosure, the maximum size of the first accommodating space 11b can be regarded as the width of the first surface 11a along the first axis AX1; and the maximum size of the second accommodating space 13b can be regarded as the width of the third surface 13a along the first axis AX1.

[0084] The above configuration can make the mass distribution of the tactile feedback mechanism 100 more uniform, thereby achieving the effect of improving the stability and reliability of the tactile feedback mechanism 100.

[0085] According to some embodiments of the present disclosure, on the first axis AX1, a maximum size of the first accommodating space 11 b is different from a maximum size of the second accommodating space 13 b .

[0086] According to some embodiments of the present disclosure, along the first axis AX1, the maximum size of the first accommodating space 11b is smaller than the maximum size of the second accommodating space 13b. This configuration can increase the upward motion range of the tactile feedback mechanism 100, allowing the tactile feedback mechanism 100 to provide different vibration feedback, thereby allowing the user to experience a variety of vibrations.

[0087] According to some embodiments of the present disclosure, along the first axis AX1, the maximum dimension of the first accommodating space 11b is greater than the maximum dimension of the second accommodating space 13b. This configuration increases the downward motion range of the tactile feedback mechanism 100, enabling the tactile feedback mechanism 100 to provide different vibration feedback, thereby allowing the user to experience a variety of vibrations. Furthermore, it effectively prevents the movable portion 20 from contacting the second cover 14, thereby preventing damage.

[0088] As previously described, according to some embodiments of the present disclosure, on the first axis AX1, the maximum distance between the first surface 11a of the first frame body 11 and the second surface 12a of the first cover body 12 is different from the maximum distance between the third surface 13a of the second frame body 13 and the fourth surface 14a of the second cover body 14. It should be noted that, according to some embodiments of the present disclosure, the maximum distance between the first surface 11a and the second surface 12a may refer to the maximum distance from the lower edge of the first surface 11a to the second surface 12a when viewed along the first axis AX1; and the maximum distance between the third surface 13a and the fourth surface 14a may refer to the maximum distance from the lower edge of the third surface 13a to the fourth surface 14a when viewed along the first axis AX1.

[0089] As described above, according to some embodiments of the present disclosure, on the first axis AX1, the maximum distance between the first surface 11a of the first frame 11 and the second surface 12a of the first cover 12 is greater than the maximum distance between the third surface 13a of the second frame 13 and the fourth surface 14a of the second cover 14.

[0090] According to some embodiments of the present disclosure, the first piezoelectric element 31 may penetrate the first weight element 21. Figure 2 As shown, the dotted line in the first counterweight element 21 represents the portion of the first piezoelectric element 31 that passes through the first counterweight element 21. It should be noted that the dotted line here is shown only for the convenience of explanation and observation. In fact, according to some embodiments of the present disclosure, the dotted line here may not be visible to the naked eye. The first piezoelectric element 31 has a piezoelectric material, so that when the first piezoelectric element 31 receives an external current, it can move relative to the fixed portion 10. According to some embodiments of the present disclosure, no part of the first piezoelectric element 31 is fixedly connected to the fixed portion 10.

[0091] The driving assembly 30 can drive the movable portion 20 to move within a range of motion (not shown) relative to the fixed portion 10. According to some embodiments of the present disclosure, the movable portion 20 may not move beyond the aforementioned range of motion unless the tactile feedback mechanism 100 is subjected to external impact.

[0092] like Figure 3As shown, the first elastic element 41 has a plate-like structure. According to some embodiments of the present disclosure, the movable portion 20 can be movably connected to the fixed portion 10 via the first elastic element 41, and the first piezoelectric element 31 can be movably connected to the fixed portion 10 via the first elastic element 41. Furthermore, according to some embodiments of the present disclosure, the driving assembly 30 can be electrically connected to an external circuit via the first elastic element 41.

[0093] The first elastic element 41 may include a first movable portion connection end 411 and a first fixed portion connection end 412. The first movable portion connection end 411 may be located at the center of the first elastic element 41, while the first fixed portion connection end 412 may be located at the outer edge of the first elastic element 41.

[0094] According to some embodiments of the present disclosure, the first movable portion connection end 411 is fixedly connected to the movable portion 20, and the first fixed portion connection end 412 is fixedly connected to the first surface 11a of the first frame 11. According to some embodiments of the present disclosure, when viewed along the first axis AX1, the first elastic element 41 at least partially overlaps the first surface 11a of the first frame 11.

[0095] like Figure 3 As shown, the second elastic element 42 has a plate-like structure. According to some embodiments of the present disclosure, the movable portion 20 can be movably connected to the fixed portion 10 via the second elastic element 42, and the first piezoelectric element 31 can be movably connected to the fixed portion 10 via the second elastic element 42. Moreover, according to some embodiments of the present disclosure, the driving assembly 30 can be electrically connected to an external circuit via the second elastic element 42.

[0096] The second elastic element 42 may include a second movable portion connection end 421 and a second fixed portion connection end 422. The second movable portion connection end 421 may be located at the center of the second elastic element 42, while the second fixed portion connection end 422 may be located at the outer edge of the second elastic element 42.

[0097] According to some embodiments of the present disclosure, the second movable portion connection end 421 is fixedly connected to the movable portion 20, and the second fixed portion connection end 422 is fixedly connected to the third surface 13a of the second frame 13. According to some embodiments of the present disclosure, when viewed along the first axis AX1, the second elastic element 42 at least partially overlaps the third surface 13a of the second frame 13.

[0098] According to some embodiments of the present disclosure, the elastic coefficient of the first elastic element 41 may be the same as the elastic coefficient of the second elastic element 42 , so that the tactile feedback mechanism 100 has uniform vibration feedback.

[0099] According to some embodiments of the present disclosure, the elastic coefficient of the first elastic element 41 may be different from the elastic coefficient of the second elastic element 42. According to some embodiments of the present disclosure, the elastic coefficient of the first elastic element 41 may be smaller than the elastic coefficient of the second elastic element 42. According to some embodiments of the present disclosure, the elastic coefficient of the first elastic element 41 may be greater than the elastic coefficient of the second elastic element 42. The above configuration can enable the tactile feedback mechanism 100 to provide different vibration feedback, thereby allowing the user to experience a variety of vibrations.

[0100] According to some embodiments of the present disclosure, when the movable portion 20 is located at any position within the aforementioned range of motion, the movable portion 20 and the first movable portion connecting end 411 of the first elastic element 41 do not contact the first surface 11a of the first frame body 11. According to some embodiments of the present disclosure, when the movable portion 20 is located at any position within the aforementioned range of motion, the movable portion 20 and the second elastic element 42 do not contact the fourth surface 14a of the second cover 14.

[0101] According to some embodiments of the present disclosure, a current of an external circuit may flow from the first elastic element 41 into the first piezoelectric element 31 , and the current may flow out from the second elastic element 41 .

[0102] See also Figure 4 , Figure 4 FIG2 is a schematic diagram of a tactile feedback mechanism 200 according to some embodiments of the present disclosure. The tactile feedback mechanism 200 has a similar structure and configuration to the tactile feedback mechanism 100 , and similarities are not repeated here.

[0103] The main difference between the tactile feedback mechanism 200 and the tactile feedback mechanism 100 is that the driving component 30 of the tactile feedback mechanism 200 may further include a second piezoelectric element 32 , and the first piezoelectric element 31 of the driving component 30 of the tactile feedback mechanism 200 does not penetrate the first weight element 21 .

[0104] See also Figure 4 According to some embodiments of the present disclosure, the first piezoelectric element 31 may include a connection surface 31 a , and the second piezoelectric element 32 may include a connection surface 32 a .

[0105] The first piezoelectric element 31 is disposed on the movable portion 20, and the second piezoelectric element 32 is disposed below the movable portion 20. The first weight element 21 may include a first surface 21a and a second surface 21b. The first surface 21a of the first weight element 21 may face the connection surface 31a of the first piezoelectric element 31, and the second surface 21b of the first weight element 21 may face the connection surface 32a of the second piezoelectric element 32.

[0106] The first weight element 21 of the movable portion 20 is fixedly connected to at least a first piezoelectric element 31 and a second piezoelectric element 32. According to some embodiments of the present disclosure, a connection surface 31a of the first piezoelectric element 31 is connected to the first surface 21a of the first weight element 21, and a connection surface 32a of the second piezoelectric element 32 is connected to the second surface 21b of the first weight element 21.

[0107] The first piezoelectric element 31 , the first weight element 21 , and the second piezoelectric element 32 may be arranged along the first axis AX1 , and the first weight element 21 may be located between the first piezoelectric element 31 and the second piezoelectric element 32 .
