[0070] The following discloses many different implementation methods or examples to implement the different features provided. The following describes embodiments of specific elements and their arrangements to illustrate the present disclosure. Of course, these embodiments are only for illustration and should not limit the scope of the present disclosure. For example, when it is mentioned in the specification that a first feature component is formed on a second feature component, it may include an embodiment where the first feature component and the second feature component are in direct contact, and may also include an embodiment where there are other features between the first feature component and the second feature component. In other words, the first feature component and the second feature component are not in direct contact.
[0071] In addition, repeated reference numerals and designations may be used in different embodiments. These repetitions are for the purpose of simplicity and clarity in describing the present disclosure only and do not represent a particular relationship between the different embodiments and / or configurations discussed. Further, forming, connecting to, and / or coupling to another feature component in the present disclosure may include embodiments in which the feature components are formed in direct contact, and may also include embodiments in which additional feature components may be formed between the above-mentioned feature components such that the above-mentioned feature components may not be in direct contact. Further, spatial relative terms such as "vertical", "above", "upper", "lower", "bottom", and similar terms (such as "downwardly", "upwardly", etc.) may be used herein. These spatial relative terms are for the purpose of facilitating the description of the relationship between one or more elements or features in the drawings and another element or feature. These spatial relative terms are intended to cover different orientations of the device including the features.
[0072] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. It is understood that such terms, such as those defined in a commonly used dictionary, should be interpreted as having a meaning that is consistent with the context of the relevant art and the present disclosure, and should not be interpreted in an idealized or overly formal manner unless specifically defined herein.
[0073] Furthermore, ordinal numbers such as "first", "second", etc. used in the specification and claims to modify elements of the claims do not themselves imply and represent any prior ordinal numbers of the claimed elements, nor do they represent the order of one claimed element and another claimed element, or the order in a manufacturing method. The use of multiple ordinal numbers is only used to clearly distinguish one claimed element having a certain name from another claimed element having the same name.
[0074] In addition, in some embodiments of the present disclosure, terms related to joining and connecting such as "connect", "interconnect", etc., unless specifically defined, may refer to two structures in direct contact, or may also refer to two structures not in direct contact, with other structures disposed between the two structures. And such terms related to joining and connecting may also include cases where both structures are movable, or both structures are fixed.
[0075] First, please refer to Figure 1, a vibration module 1-100 according to an embodiment of the present disclosure can be installed in an electronic device 1-1 to generate vibrations. The electronic device 1-1 can be, for example, a smart phone or a tablet computer. When generating vibrations, the vibration module 1-100 can receive a current from outside the vibration module 1-100 and generate an electromagnetic driving force, which can interact with a magnetic field to cause the vibration module 1-100 to vibrate, and thus the user of the electronic device 1-1 can feel the vibration effect. It should be noted that Figure 1 The positional and size relationships between the vibration module 1-100 and the electronic device 1-1 shown in are only an example, and do not limit the positional and size relationships between the vibration module 1-100 and the electronic device 1-1. In fact, the vibration module 1-100 can be installed at different positions in the electronic device 1-1 according to different requirements.
[0076] Please refer to Figure 2A and Figure 2B , Figure 2A is a perspective view of the vibration module 1-100, and Figure 2B is an exploded view of the vibration module 1-100. As Figure 2A shown, the vibration module 1-100 has a main shaft 1-M, and the main shaft 1-M passes through the center 1-F of the vibration module 1-100. Figure 2B shown, the vibration module 1-100 includes a fixing part 1-110, a first vibration part 1-120 and a connecting member 1-T. The fixing part 1-110 includes a top plate 1-111, a bottom plate 1-112, an outer frame 1-113 and two covering elements 1-114. The first vibration part 1-120 includes a first moving member 1-121, two first driving components 1-122, a first elastic element 1-123, a glue groove 1-124, a position sensing component 1-125, a first circuit component 1-126 and two supporting elements 1-127. The first moving member 1-121 includes a first moving member body 1-1211 and two first moving member connecting parts 1-1212. Each first driving component 1-122 includes a magnetic conductive element 1-1221, a first magnetic element 1-1222 and two first coils 1-1223.
[0077] Please refer to Figure 3A , Figure 3A is a schematic diagram of the fixing part 1-110 of the vibration module 1-100. The outer frame 1-113 is located between the top plate 1-111 and the bottom plate 1-112. The top plate 1-111 covers the upper part of the outer frame 1-113, and the bottom plate 1-112 covers the lower part of the outer frame 1-113. Therefore, the main shaft 1-M also passes through the top plate 1-111 and the bottom plate 1-112. The top plate 1-111, the bottom plate 1-112 and the outer frame 1-113 can be made of non-ferromagnetic metal, and the density of this non-ferromagnetic metal is preferably greater than the density of the plastic material. Please refer toFigure 3B , Figure 3B It is a schematic diagram of the top plate 1-111, the bottom plate 1-112 and the outer frame 1-113. The top plate 1-111 has a perforation 1-1111, and the bottom plate 1-112 has a perforation 1-1121, where the perforation 1-1121 is drawn in dotted lines. The perforation 1-1111 and the perforation 1-1121 are beneficial to the positioning of the components arranged in the vibration module 1-100 and the assembly of the vibration module 1-100.
[0078] Please refer to Figure 3A again. Two covering elements 1-114 are respectively located above the top plate 1-111 and below the bottom plate 1-112. The covering element 1-114 located above the top plate 1-111 covers the perforation 1-1111, and the covering element 1-114 located below the bottom plate 1-112 covers the perforation 1-1121. That is to say, when observing along the direction of the main axis 1-M, the covering element 1-114 located above the top plate 1-111 completely overlaps with the perforation 1-1111, and the covering element 1-114 located below the bottom plate 1-112 completely overlaps with the perforation 1-1121. In this way, neither the perforation 1-1111 nor the perforation 1-1121 is exposed to the outside, so it is possible to prevent external dust or water from entering the vibration module 1-100 through the perforation 1-1111 or the perforation 1-1121, thereby achieving the effects of dust prevention and waterproofing. The covering element 1-114 can be a shielding material such as a light-shielding sheet.
[0079] Figure 3C It is a schematic diagram of the outer frame 1-113, and Figure 3D is a partial schematic diagram of the outer frame 1-113. As Figure 3C shown, the outer frame 1-113 is formed centered on the main axis 1-M, and the outer frame 1-113 includes two welding parts 1-1131 and a gap 1-1132. The welding parts 1-1131 are respectively located on both sides of the outer frame 1-113 and extend along the outer frame 1-113. As Figure 3D shown, the gap 1-1132 of the outer frame 1-113 traverses the outer frame 1-113 in the direction of the main axis 1-M. That is to say, the outer frame 1-113 is disconnected by the gap 1-1132 at the gap 1-1132, so the outer frame 1-113 is not connected integrally in a circumferential manner, and the gap 1-1132 can be shielded by components such as a circuit board, a plastic component, solder or a light-shielding sheet to prevent foreign objects from entering the vibration module 1-100. In fact, the outer frame 1-113 can be formed by bending a metal sheet centered on the main axis 1-M instead of being cast. In this way, the manufacturing complexity of the vibration module 1-100 can be reduced, thereby reducing the manufacturing cost of the vibration module 1-100.
[0080] Figure 4A and Figure 4BPartial schematic views of the top plate 1-111 and the outer frame 1-113 according to different embodiments. As Figure 4A shown, in one embodiment, the top plate 1-111 is not directly connected to the outer frame 1-113, and when observed along the main axis 1-M direction, there is a gap 1-C1 between the top plate 1-111 and the outer frame 1-113. As Figure 4B shown, in another embodiment, the top plate 1-111 is not directly connected to the outer frame 1-113, and when observed along the direction perpendicular to the main axis 1-M, there is a gap 1-C2 between the top plate 1-111 and the outer frame 1-113. As Figure 4A and Figure 4B shown, a connecting member 1-T is provided between the top plate 1-111 and the outer frame 1-113 to fix the top plate 1-111 to the outer frame 1-113. The connecting member 1-T can be made of materials such as a light-shielding sheet, solder, or adhesive.
[0081] Figure 4C and Figure 4D Partial schematic views of the bottom plate 1-112 and the outer frame 1-113 according to different embodiments. As Figure 4C shown, in one embodiment, the bottom plate 1-112 is not directly connected to the outer frame 1-113, and when observed along the main axis 1-M direction, there is a gap 1-C3 between the bottom plate 1-112 and the outer frame 1-113. As Figure 4D shown, in another embodiment, the bottom plate 1-112 is not directly connected to the outer frame 1-113, and when observed along the direction perpendicular to the main axis 1-M, there is a gap 1-C4 between the bottom plate 1-112 and the outer frame 1-113. As Figure 4C and Figure 4D shown, a connecting member 1-T is provided between the bottom plate 1-112 and the outer frame 1-113 to fix the bottom plate 1-112 to the outer frame 1-113. Similarly, the connecting member 1-T can be made of materials such as a light-shielding sheet, solder, or adhesive.
[0082] Figure 5A Schematic view of the outer frame 1-113 and the first vibration part 1-120. As Figure 5A shown, the first vibration part 1-120 is arranged inside the outer frame 1-113 of the fixing part 1-110. Figure 5B Schematic view of the first moving part 1-121. As Figure 5B shown, the first moving part 1-121 has a plate-like structure, and the outer frame 1-113 of the fixing part 1-110 surrounds the first moving part 1-121 with the main axis 1-M as the center (reference can be made to Figure 5A ). The first moving part connecting portion 1-1212 of the first moving part 1-121 protrudes from the first moving part body 1-1211.
[0083] Please refer to Figure 5A, the first driving components 1-122 are respectively located at different ends of the first moving member 1-121, and the first driving components 1-122 drive the first moving member 1-121 to move relative to the fixed portion 1-110. Specifically, the first driving components 1-122 drive the first moving member 1-121 to move relative to the fixed portion 1-110 along a first direction 1-D1, and the first direction 1-D1 is not parallel to the main shaft 1-M. More specifically, the first direction 1-D1 is perpendicular to the main shaft 1-M.
[0084] Please refer to Figure 6 , Figure 6 is a schematic diagram of the first driving component 1-122. In the embodiment shown in Figure 6 , each first driving component 1-122 includes two first coils 1-1223. In some embodiments, each first driving component 1-122 may include more than two first coils 1-1223. However, in other embodiments, each first driving component 1-122 may include only one first coil 1-1223. The magnetic conductive element 1-1221 can be connected to the first moving member body 1-1211 of the first moving member 1-121 (not shown in Figure 6In one embodiment, the magnetic conductive element 1-1221 may have holes (not shown in the figure) to adjust the magnetic force intensity generated by the first magnetic element 1-1222. Two first coils 1-1223 are respectively located above and below the first magnetic element 1-1222. The first coil 1-1223 located below the first magnetic element 1-1222 is the first coil 1-1223a, and the first coil 1-1223 located above the first magnetic element 1-1222 is the first coil 1-1223b. When observed along the main axis 1-M direction, the first coil 1-1223a and the first coil 1-1223b at least partially overlap each other. The magnetic conductive element 1-1221 is disposed between the first magnetic element 1-1222 and the first coil 1-1223a. Specifically, the magnetic conductive element 1-1221 is disposed on a surface 1-1222a of the first magnetic element 1-1222 facing the first coil 1-1223a. The first magnetic element 1-1222 may be a permanent magnet. In this embodiment, the first magnetic element 1-1222 includes two permanent magnets, and the magnetic poles of the permanent magnets are arranged staggeredly. That is, when the north pole of one of the permanent magnets faces the magnetic conductive element 1-1221, the south pole of the other permanent magnet faces the magnetic conductive element 1-1221, and vice versa. The shortest distance 1-A1 between the magnetic conductive element 1-1221 and the first coil 1-1223a is substantially the same as the shortest distance 1-A2 between the first magnetic element 1-1222 and the first coil 1-1223b. Since the magnetic conductive element 1-1221 has a thickness 1-B, the shortest distances between the first magnetic element 1-1222 and the first coil 1-1223a and the first coil 1-1223b are different. In this way, during operation, error variables can be reduced, making the vibration module 1-100 more stable.
[0085] Please refer to again Figure 5A, the first elastic element 1-123 includes two reed pieces 1-1231. In other embodiments, the first elastic element 1-123 may include more than two reed pieces 1-1231. Each reed piece 1-1231 is fixedly connected to (e.g., welded to) the first moving member connecting portion 1-1212 of the first moving member 1-121 and is fixed to the welding portion 1-1131 of the outer frame 1-113 by welding. In this way, the first moving member 1-121 can be movably connected to the outer frame 1-113 through the reed pieces 1-1231, and the first moving member 1-121 does not contact the bottom plate 1-112 due to the support of the reed pieces 1-1231. The two reed pieces 1-1231 are respectively located on both sides of the first moving member 1-121, and the reed pieces 1-1231 are respectively arranged in opposite directions. More specifically, the two reed pieces 1-1231 respectively include a recessed structure, and an opening of this recessed structure faces different directions. In this way, the first moving member 1-121 can be prevented from generating a movement in a direction other than the first direction 1-D1. For example, the first moving member 1-121 can be prevented from generating a movement along the main axis 1-M direction or a direction perpendicular to the first direction 1-D1.
[0086] Figure 7 FIG. is a schematic diagram of the reed piece 1-1231. Each reed piece 1-1231 includes a first section 1-1232, a second section 1-1233, and a bending portion 1-1234. The first section 1-1232 is connected to the second section 1-1233 through the bending portion 1-1234. The first section 1-1232 and the bending portion 1-1234 are bounded by a dashed line 1-W1, and the second section 1-1233 and the bending portion 1-1234 are bounded by a dashed line 1-W2. The first section 1-1232 includes a first straight segment 1-1232a, a first bent segment 1-1232b, and a first reversed bent segment 1-1232c that extend at different angles, where the first straight segment 1-1232a and the first bent segment 1-1232b are bounded by a dashed line 1-W3, and the first bent segment 1-1232b and the first reversed bent segment 1-1232c are bounded by a dashed line 1-W4. The second section 1-1233 includes a second straight segment 1-1233a, a second bent segment 1-1233b, and a second reversed bent segment 1-1233c that extend at different angles, where the second straight segment 1-1233a and the second bent segment 1-1233b are bounded by a dashed line 1-W5, and the second bent segment 1-1233b and the second reversed bent segment 1-1233c are bounded by a dashed line 1-W6. When observed in a direction perpendicular to the main axis 1-M, the first bent segment 1-1232b and the second bent segment 1-1233b at least partially overlap.
[0087] After the first bending section 1-1232b extends from the dashed line 1-W3 and bends by more than 180 degrees, it is connected to the first reverse folding section 1-1232c. When observed along the direction perpendicular to the main axis 1-M, the first bending section 1-1232b and the first reverse folding section 1-1232c at least partially overlap. Similarly, after the second bending section 1-1233b extends from the dashed line 1-W5 and bends by more than 180 degrees, it is connected to the second reverse folding section 1-1233c. When observed along the direction perpendicular to the main axis 1-M, the second bending section 1-1233b and the second reverse folding section 1-1233c at least partially overlap. In this way, the first bending section 1-1232b, the first reverse folding section 1-1232c, the second bending section 1-1233b, and the second reverse folding section 1-1233c can facilitate the welding of the reed 1-1231 to the outer frame 1-113 and the first moving part connecting portion 1-1212, and can avoid the breakage of the reed 1-1231.
[0088] Please refer to again Figure 5A , the first bending section 1-1232b is fixedly connected to (e.g., welded to) the first moving part connecting portion 1-1212 of the first moving part 1-121. A surface 1-1232b' of the first bending section 1-1232b is flush with a surface 1-1212a of the first moving part connecting portion 1-1212 and is not parallel to the main axis 1-M.
[0089] Please refer to simultaneously Figure 8A and Figure 8B , Figure 8A is a schematic diagram of the first magnetic element 1-1222 and the glue groove 1-124, and Figure 8B is a partial cross-sectional view along the Figure 2A 1-A-1-A section line in Figure 6 . The glue groove 1-124 is arranged adjacent to the first magnetic element 1-1222. The first magnetic element 1-1222 faces a surface 1222b of the first coil 1-1223b (the surface of the first magnetic element 1-1222 without the magnetic conductive element 1-1221) protrudes from the glue groove 1-124. In this way, the shortest distance 1-A1 between the magnetic conductive element 1-1221 and the first coil 1-1223a is substantially the same as the shortest distance 1-A2 between the surface 1222b and the first coil 1-1223b (refer to
[0090] Please refer to Figure 9A , Figure 9ASchematic diagram of the first coil 1-1223 and the position sensing component 1-125. The position sensing component 1-125 may include a Hall sensor, which is disposed on the first circuit component 1-126 (not shown in Figure 9A and can be referred to Figure 5A . The position sensing component 1-125, shown in dashed lines, senses the movement of the first moving member 1-121 relative to the fixed portion 1-110. More specifically, the position sensing component 1-125 can sense the movement of the first moving member 1-121 along the first direction 1-D1 relative to the fixed portion 1-110. As Figure 9A shown, there is a non-zero distance 1-S between the center of the position sensing component 1-125 and a winding axis 1-1123a of the first coil 1-1223. In this way, the effect of miniaturizing the vibration module 1-100 can be achieved, and the risk of damage to the first circuit component 1-126 due to excessive extension can be avoided. The position sensing component 1-125 can also sense the vibration frequency of the vibration module 1-100 to determine whether the vibration frequency of the vibration module 1-100 is the required vibration frequency.
[0091] Please refer to Figure 9B , Figure 9B which is a schematic diagram of the first circuit component 1-126. The first circuit component 1-126 has a first circuit component body 1-1261, two first extension portions 1-1262, two second extension portions 1-1263 and an external connection portion 1-1264. The first circuit component body 1-1261 has a long plate shape. The first extension portions 1-1262 and the second extension portions 1-1263 extend from above and below the first circuit component body 1-1261 respectively to be electrically connected to the first coil 1-1223 (refer to Figure 5A ). Among them, the position sensing component 1-125 is disposed on the second extension portion 1-1263 (see Figure 5A ). The external connection portion 1-1264 extends from the first circuit component body 1-1261 and receives external current. Therefore, the first circuit component 1-126 can conduct the external current to the first coil 1-1223.
[0092] Please refer to Figure 5A , Figure 10A and Figure 10B again, Figure 10A which is a schematic diagram of the first moving member 1-121 and the first circuit component 1-126 observed along the first direction 1-D1, and Figure 10B which is a schematic diagram of the first moving member 1-121 and the first circuit component 1-126 observed along a second direction 1-D2, where the second direction 1-D2 is not parallel to the main axis 1-M and the first direction 1-D1. As Figure 5AAs shown, the first circuit component 1-126 extends above the first coil 1-1223b to be electrically connected to the first coil 1-1223b. When observed along the main axis 1-M direction, the first moving member 1-121 and the first circuit component 1-126 at least partially overlap. As Figure 10A shown, the first circuit component 1-126 extends below the first coil 1-1223a to be electrically connected to the first coil 1-1223a. When observed along the first direction 1-D1 not parallel to the main axis 1-M, the first moving member 1-121 and the first circuit component 1-126 do not overlap. As Figure 10B shown, when observed along the second direction 1-D2, the first moving member 1-121 (shown in dashed lines) and the first circuit component 1-126 at least partially overlap. Specifically, as Figure 10A shown, when observed along the first direction 1-D1, the first circuit component 1-126 generally presents a C or U shape, and a part of the first moving member 1-121 is accommodated between the first circuit components 1-126 presenting a C or U shape. In this way, the first circuit component 1-126 can be electrically connected to the first coil 1-1223a and the first coil 1-1223b, and the extension length of the first circuit component 1-126 is reduced to achieve the effect of miniaturization. The first circuit component 1-126 is electrically connected to each first driving component 1-122 to supply current to the first driving component 1-122, so that the first driving component 1-122 can drive the first moving member 1-121 to move.
[0093] Please also refer to Figure 11A and Figure 11B , Figure 11A which are schematic diagrams of one of the first driving components 1-122 and the support element 1-127, Figure 11B and Figure 2A is a cross-sectional view along the section line 1-B-1-B in Figure 11A and Figure 11BAs shown, the support element 1-127 is disposed between the first drive assembly 1-122 and the top plate 1-111 and the bottom plate 1-112 of the fixing portion 1-110. When viewed in a direction perpendicular to the main shaft 1-M, the first circuit assembly 1-126 and the support element 1-127 at least partially overlap. Specifically, when viewed in a direction perpendicular to the main shaft 1-M, the first circuit assembly 1-126 and the support element 1-127 are flush. In this way, the first vibrating portion 1-120 can be more easily connected to the top plate 1-111 and the bottom plate 1-112 of the fixing portion 1-110. The first vibrating portion 1-120 can be connected to the top plate 1-111 and the bottom plate 1-112 by providing a connecting member 1-T between the top plate 1-111 and the bottom plate 1-112 and the support element 1-127. The connecting member 1-T for connecting the first vibrating portion 1-120 to the top plate 1-111 and the bottom plate 1-112 can be made of materials such as solder or adhesive. The support element 1-127 can be made of metal. In one embodiment, the support element 1-127 can be made of a ferromagnetic metal or a ferromagnetic alloy, such as ferromagnetic metals or their alloys such as iron, cobalt, nickel, etc. In another embodiment, the support element 1-127 can be made of a non-ferromagnetic metal or a non-ferromagnetic alloy.
[0094] In summary, the embodiments of the present disclosure provide a vibration module 1-100 that can stably generate vibrations in a single direction, and the vibration module 1-100 disclosed in the embodiments of the present disclosure has a low production cost and has been miniaturized.
[0095] Next, please refer to Figure 12 , a vibration module 2-200 according to an embodiment of the present disclosure can be installed in an electronic device 2-2 to generate vibrations. The electronic device 2-2 can be, for example, a smart smartphone or a tablet computer. When generating vibrations, the vibration module 2-200 can receive a current from outside the vibration module 2-200 and generate an electromagnetic driving force, and this electromagnetic driving force can interact with a magnetic field to cause the vibration module 2-200 to generate vibrations, thereby making the user of the electronic device 2-2 feel the vibration effect. It should be noted that Figure 12 The positional and size relationship between the vibration module 2-200 and the electronic device 2-2 shown in
[0096] is only an example, and does not limit the positional and size relationship between the vibration module 2-200 and the electronic device 2-2. In fact, the vibration module 2-200 can be installed at different positions in the electronic device 2-2 according to different requirements. Figure 13A and Figure 13B , Figure 13A is a perspective view of the vibration module 2-200, and Figure 13B is an exploded view of the vibration module 2-200. As Figure 13AAs shown, the vibration module 2-200 has a main shaft 2-M, and the main shaft 2-M passes through the center 2-F of the vibration module 2-200. Figure 13B As shown, the vibration module 2-200 includes a fixing part 2-210, a first vibration part 2-220 and a connecting part 2-T. The fixing part 2-210 includes a top plate 2-211, a bottom plate 2-212, an outer frame 2-213 and two covering elements 2-214. The first vibration part 2-220 includes a first moving part 2-221, a first driving assembly 2-222, a first elastic element 2-223 and a first circuit assembly 2-224. The first driving assembly 2-222 includes a first driving coil 2-2221 and a first driving magnetic element 2-2222.
[0097] Please refer to Figure 14A , Figure 14A FIG. is a schematic diagram of the fixing part 2-210. The outer frame 2-213 is located between the top plate 2-211 and the bottom plate 2-212. The top plate 2-211 covers the upper part of the outer frame 2-213, and the bottom plate 2-212 covers the lower part of the outer frame 2-213. Therefore, the main shaft 2-M also passes through the top plate 2-211 and the bottom plate 2-212. The top plate 2-211, the bottom plate 2-212 and the outer frame 2-213 can be made of non-ferromagnetic metal, and the density of this non-ferromagnetic metal is preferably greater than the density of the plastic material. Please refer to Figure 14B , Figure 14B FIG. is a schematic diagram of the top plate 2-211, the bottom plate 2-212 and the outer frame 2-213. The top plate 2-211 has a perforation 2-2111, and the bottom plate 2-212 has a perforation 2-2121, where the perforation 2-2121 is drawn in dotted line. The perforation 2-2111 and the perforation 2-2121 are beneficial to the positioning of the components arranged in the vibration module 2-200 and the assembly of the vibration module 2-200.
[0098] Please refer to again Figure 14A , two covering elements 2-214 are respectively located above the top plate 2-211 and below the bottom plate 2-212. The covering element 2-214 located above the top plate 2-211 covers the perforation 2-2111, and the covering element 2-214 located below the bottom plate 2-212 covers the perforation 2-2121. That is to say, when observing along the direction of the main shaft 2-M, the covering element 2-214 located above the top plate 2-211 completely overlaps with the perforation 2-2111, and the covering element 2-214 located below the bottom plate 2-212 completely overlaps with the perforation 2-2121. In this way, neither the perforation 2-2111 nor the perforation 2-2121 is exposed to the outside, so it can prevent external dust or water from entering the vibration module 2-200 through the perforation 2-2111 or the perforation 2-2121, thereby achieving the effects of dust prevention and waterproofing. The covering element 2-214 can be a shielding material such as a light-shielding sheet.
[0099] Figure 14C is a schematic view of the outer frame 2-213, and Figure 14D is a partial schematic view of the outer frame 2-213. As Figure 14C shown, the outer frame 2-213 is formed around the main axis 2-M, and the outer frame 2-213 includes two welding parts 2-2131 and a gap 2-2132. The welding parts 2-2131 are respectively located on both sides of the outer frame 2-213 and extend along the outer frame 2-213. As Figure 14D shown, the gap 2-2132 of the outer frame 2-213 transversely crosses the outer frame 2-213 in the direction of the main axis 2-M. That is to say, the outer frame 2-213 is disconnected by the gap 2-2132 at the gap 2-2132. Therefore, the outer frame 2-213 is not connected integrally in a circumferential manner, and the gap 2-2132 can be shielded by, for example, a circuit board, a plastic component, solder or a light-shielding sheet to prevent foreign objects from entering the vibration module 2-200. In fact, the outer frame 2-213 can be formed by bending a metal sheet around the main axis 2-M instead of being cast. In this way, the manufacturing complexity of the vibration module 2-200 can be reduced, thereby reducing the manufacturing cost of the vibration module 2-200.
[0100] Figure 15A and Figure 15B are partial schematic views of the top plate 2-211 and the outer frame 2-213 according to different embodiments. As Figure 15A shown, in one embodiment, the top plate 2-211 is not directly connected to the outer frame 2-213, and there is a gap 2-C1 between the top plate 2-211 and the outer frame 2-213 when observed along the direction of the main axis 2-M. As Figure 15B shown, in another embodiment, the top plate 2-211 is not directly connected to the outer frame 2-213, and there is a gap 2-C2 between the top plate 2-211 and the outer frame 2-213 when observed along the direction perpendicular to the main axis 2-M. As Figure 15A and Figure 15B shown, a connecting member 2-T is provided between the top plate 2-211 and the outer frame 2-213 to fix the top plate 2-211 to the outer frame 2-213. The connecting member 2-T can be made of materials such as a light-shielding sheet, solder or adhesive.
[0101] Figure 15C and Figure 15D are partial schematic views of the bottom plate 2-212 and the outer frame 2-213 according to different embodiments. As Figure 15C shown, in one embodiment, the bottom plate 2-212 is not directly connected to the outer frame 2-213, and there is a gap 2-C3 between the bottom plate 2-212 and the outer frame 2-213 when observed along the direction of the main axis 2-M. As Figure 15DAs shown, in another embodiment, the bottom plate 2-212 is not directly connected to the outer frame 2-213, and there is a gap 2-C4 between the bottom plate 2-212 and the outer frame 2-213 when viewed in a direction perpendicular to the main shaft 2-M. As Figure 15C and Figure 15D shown, a connecting member 2-T is provided between the bottom plate 2-212 and the outer frame 2-213 to fix the bottom plate 2-212 to the outer frame 2-213. Similarly, the connecting member 2-T can be made of materials such as a light-shielding sheet, solder, or adhesive.
[0102] Please refer to Figure 16 , Figure 16 which is a schematic diagram of the top plate 2-211, the bottom plate 2-212, the outer frame 2-213, and the first vibration part 2-220, where the outer frame 2-213 is shown in dashed lines. As Figure 16 shown, the first vibration part 2-220 is disposed within the top plate 2-211 and the bottom plate 2-212 of the fixing part 2-210. In one embodiment, the first moving member 2-221 can be disc-shaped. However, the shape of the first moving member 2-221 can be adjusted according to actual requirements. The first driving assembly 2-222 drives the first moving member 2-221 to move along the direction of the main shaft 2-M relative to the fixing part 2-210. The first elastic element 2-223 is disposed on a first side 2-2211 of the first moving member 2-221, and the first moving member 2-221 is movably connected to the bottom plate 2-212 of the fixing part 2-210 via the first elastic element 2-223. A first circuit assembly 2-224 is disposed on a second side 2-2212 of the first moving member 2-221 relative to the first side 2-2211. The main shaft 2-M passes through the first moving member 2-221, so the main shaft 2-M passes through the first side 2-2211 and the second side 2-2212. The first circuit assembly 2-224 is connected to the first moving member 2-221 by soldering or bonding, and the first circuit assembly 2-224 is connected to the top plate 2-211 and the outer frame 2-213 via the connecting member 2-T (the connecting member 2-T here can be fixing materials such as solder or adhesive). In other words, the first moving member 2-221 is connected to the top plate 2-211 and the outer frame 2-213 of the fixing part 2-210 via the first circuit assembly 2-224. The first circuit assembly 2-224 has a flexible structure such that the first circuit assembly 2-224 will not break when the first moving member 2-221 moves. In the direction of the main shaft 2-M, the elastic coefficient of the first elastic element 2-223 is greater than that of the first circuit assembly 2-224.
[0103] Please refer to Figure 17A , Figure 17B and Figure 17C . Figure 17A which is a schematic diagram of the first moving member 2-221 and the first circuit assembly 2-224, Figure 17Bis a bottom view of the first moving member 2-221 and the first elastic element 2-223, and Figure 17C is a schematic diagram of the first moving member 2-221. The first moving member 2-221 includes a receiving portion 2-2213, a recess 2-2214, and a shielding element 2-2215. As Figure 17A shown, the first circuit component 2-224 has a semi-helical shape that spirals along the main axis direction and has an internal electrical connection portion 2-2241 and an external electrical connection portion 2-2242. The internal electrical connection portion 2-2241 is located at the helical end of the first circuit component 2-224 and is disposed in the receiving portion 2-2213, while the external electrical connection portion 2-2242 is located at the non-helical end of the first circuit component 2-224. It should be noted that since the first circuit component 2-224 spirals along the main axis direction, the internal electrical connection portion 2-2241 and the external electrical connection portion 2-2242 are located in different planes. The receiving portion 2-2213 is located on the second side 2-2212 of the first moving member 2-221, and the receiving portion 2-2213 is a recessed structure for receiving at least a portion of the first circuit component 2-224, that is, the recessed structure receives at least a portion of the flexible structure of the first circuit component 2-224. The shielding element 2-2215 is disposed on the second side 2-2212 of the first moving member 2-221, and a portion of the first circuit component 2-224 is disposed on the shielding element 2-2215. As Figure 17B shown, the recess 2-2214 faces the first elastic element 2-223. In Figure 17B the illustrated embodiment, the first elastic element 2-223 may have a grid shape, so that when viewed along the main axis 2-M, the recess 2-2214 and the first elastic element 2-223 at least partially do not overlap. The size of the recess 2-2214 can be adjusted to adjust the weight configuration of the first moving member 2-221, making the first moving member 2-221 more stable. As Figure 17C shown, the recess 2-2214 corresponds to the shielding element 2-2215. That is, when viewed along the main axis 2-M direction, the recess 2-2214 and the shielding element 2-2215 at least partially overlap. In this way, the weight configuration of the first moving member 2-221 can be adjusted to make the first moving member 2-221 more stable.
[0104] Please refer to Figure 18A , Figure 18ATop view of a first moving member 2-221, a first driving assembly 2-222, and a first elastic element 2-223 according to an embodiment, where the first moving member 2-221 is represented by a dashed line. The first driving coil 2-2221 is fixedly connected to the first moving member 2-221 through a connecting member 2-T, and both the first moving member 2-221 and the first driving coil 2-2221 can be connected to the first elastic element 2-223 by welding. The first driving magnetic element 2-2222 may include two permanent magnets, and the same magnetic poles of the two permanent magnets face each other. That is, when the north pole of one of the permanent magnets faces downward, the south pole of the other permanent magnet faces upward, and vice versa. In this way, the magnetic fields of the two permanent magnets of the first driving magnetic element 2-2222 can effectively extend to the first driving coil 2-2221. Therefore, after the first driving coil 2-2221 receives an external current, it can interact with the magnetic fields of the two permanent magnets to generate an electromagnetic driving force, thereby driving the first moving member 2-221 to move relative to the fixed portion 2-210. When the first moving member 2-221 moves relative to the fixed portion 2-210, the center of mass of the vibration module 2-200 is offset, and thus the user of the electronic device 2-2 feels a vibration effect. As Figure 18A shown, in this embodiment, when viewed along the main axis 2-M direction, the first moving member 2-221, the first driving coil 2-2221, and the first elastic element 2-223 partially overlap.
[0105] Please refer to Figure 18B , Figure 18B Top view of a first moving member 2-221, a first driving assembly 2-222, and a first elastic element 2-223 according to an embodiment, where the first moving member 2-221 is represented by a dashed line. Figure 18B The embodiment shown is substantially the same as the embodiment shown in Figure 18A , and the main difference is that in the embodiment shown in Figure 18B , the positions of the first driving coil 2-2221 and the first driving magnetic element 2-2222 are exchanged with each other. The first driving magnetic element 2-2222 is fixedly connected to the first moving member 2-221 through a connecting member 2-T. Therefore, when viewed along the main axis 2-M direction, the first moving member 2-221, the first driving magnetic element 2-2222, and the first elastic element 2-223 partially overlap.
[0106] Please refer to Figure 19A , Figure 19ASchematic diagram of the first elastic element 2-223. The first elastic element 2-223 includes a first elastic element connecting portion 2-2231, and the first elastic element connecting portion 2-2231 includes three connection strengthening portions 2-2231a. The connection strengthening portions 2-2231a extend in a direction not parallel to the main shaft 2-M. It should be noted that in other embodiments, the number of the connection strengthening portions 2-2231a is not limited to three.
[0107] Please refer to Figure 19B , Figure 19B is a bottom view of the first moving member 2-221, the first driving coil 2-2221 and the first elastic element 2-223, wherein the first driving coil 2-2221 is shown by a dotted line. The first elastic element connecting portion 2-2231 can be fixedly connected to the first moving member 2-221 and the first driving coil 2-2221 by welding. Therefore, when viewed along the main shaft 2-M direction, the first elastic element connecting portion 2-2231 and the first driving coil 2-2221 do not overlap at least partially. The connection strengthening portions 2-2231a can increase the connection area between the first elastic element connecting portion 2-2231 and the first moving member 2-221 to enhance the connection strength between the first elastic element 2-223 and the first moving member 2-221.
[0108] Please refer to Figure 19C , Figure 19C is a side view of the top plate 2-211, the bottom plate 2-212 and the first vibration portion 2-220 according to an embodiment. In this embodiment, the first vibration portion 2-220 has two first elastic elements 2-223, and the two first elastic elements 2-223 are respectively connected to the top plate 2-211 and the bottom plate 2-212. The two first elastic elements 2-223 are both electrically connected to the first driving coil 2-2221. Therefore, in this embodiment, the two first elastic elements 2-223 supply external current to the first driving coil 2-2221 to generate an electromagnetic driving force.
[0109] Figure 20 is a schematic diagram of the first driving coil 2-2221 and the first circuit component 2-224. The first driving coil 2-2221 of the first driving component 2-222 is electrically connected to the first circuit component 2-224 through two lines 2221a of the first driving coil 2-2221. Therefore, in the Figure 20 shown embodiment, the first circuit component 2-224 supplies external current to the first driving coil 2-2221 to generate an electromagnetic driving force.
[0110] Figure 21A is a schematic diagram of the vibration module 2-200 according to an embodiment, wherein the top plate 2-211 and the covering element 2-214 have been omitted. As Figure 21AAs shown, in an embodiment of the present disclosure, the vibration module 2-200 further includes a second vibration part 2-250. The second vibration part 2-250 is disposed within the outer frame 2-213 of the fixing part 2-210. The second vibration part 2-250 includes a second moving member 2-251, a second driving assembly 2-252, a second elastic element 2-253, and a second circuit assembly 2-254. The first vibration part 2-220 has a first natural resonance frequency, and the second vibration part 2-250 has a second natural resonance frequency, and the second natural resonance frequency is different from the first natural resonance frequency. The second driving assembly 2-252 drives the second moving member 2-251 to move relative to the fixing part 2-210 in a direction not parallel to the main axis 2-M. The second moving member 2-251 is movably connected to the outer frame 2-213 of the fixing part 2-210 via the second elastic element 2-253. The second circuit assembly 2-254 is electrically connected to the second driving assembly 2-252 to supply an external current to the second driving assembly 2-252, thereby driving the movement of the second moving member 2-251.
[0111] Figure 21B is a side view of the first vibration part 2-220 and the second vibration part 2-250 according to an embodiment identical to Figure 21A . As Figure 21B shown, when observed along the direction perpendicular to the main axis 2-M, the maximum dimension 2-H1 of the first moving member 2-221 in the main axis 2-M direction is greater than the maximum dimension 2-H2 of the second moving member 2-251 in the main axis 2-M direction. That is to say, the maximum dimension 2-H2 of the second moving member 2-251 in the main axis 2-M direction is less than the maximum dimension 2-H1 of the first moving member 2-221 in the main axis 2-M direction. In this way, the volume and weight of the second moving member 2-251 can be reduced, and the effect of miniaturization can be achieved. The second circuit assembly 2-254 extends in a first direction 2-D1 to supply an external current to the second driving assembly 2-252. Therefore, when observed along the direction perpendicular to the main axis 2-M, the first circuit assembly 2-224 and the second circuit assembly 2-254 at least partially overlap.
[0112] Figure 21C is a side view of the first elastic element 2-223 and the second elastic element 2-253. As Figure 21C shown, when observed along the direction perpendicular to the main axis 2-M, the first elastic element 2-223 and the second elastic element 2-253 at least partially overlap. In this way, the vibration module 2-200 can be made more stable, and the internal space of the vibration module 2-200 can be effectively utilized, and the effect of miniaturization can be achieved.
[0113] Figure 21D is a schematic diagram of a vibration module 2-200' similar to Figure 21A in an embodiment. InFigure 21D In the illustrated embodiment, most of the components of the vibration module 2-200’ are the same as Figure 21A the components of the vibration module 2-200 in the illustrated embodiment. However, as Figure 21D shown, in this embodiment, the orientation of the first circuit component 2-224’ is different from Figure 21A that of the first circuit component 2-224 in the illustrated embodiment. In Figure 21A the illustrated embodiment, the first circuit component 2-224 extends in a direction opposite to that of the second circuit component 2-254. However, in Figure 21D the illustrated embodiment, the first circuit component 2-224’ extends in the direction of the second circuit component 2-254’. Therefore, in this embodiment, when viewed in the direction of the main axis 2-M, the first circuit component 2-224’ and the second circuit component 2-254’ at least partially overlap. In this way, it is more beneficial for the connection of the first circuit component 2-224’ and the second circuit component 2-254’ to an external power supply.
[0114] In one embodiment, the vibration module 2-200 may not have the second circuit component 2-254, and only supply external current to the first driving component 2-222 and the second driving component 2-252 through the first circuit component 2-224. Alternatively, in another embodiment, the vibration module 2-200 may not have the first circuit component 2-224, and only supply external current to the first driving component 2-222 and the second driving component 2-252 through the second circuit component 2-254. In this way, the weight of the vibration module 2-200 can be reduced, achieving a miniaturization effect.
[0115] In summary, the embodiments of the present disclosure provide a vibration module 2-200 that can stably generate vibrations in a single direction and two directions, and the vibration module 2-200 disclosed in the embodiments of the present disclosure has a low production cost and has been miniaturized.
[0116] Figure 22 is a schematic diagram of a feedback system 3-1 according to some embodiments of the present disclosure. The feedback system 3-1 can be disposed in an electronic device, such as a portable device like a mobile phone, a mouse, a smart bracelet, etc., or can also be disposed in various parts of an automobile (such as a steering wheel, a key), etc., to provide a feedback force to a user to inform the user of specific information in a vibrating manner. As Figure 22 shown, the feedback system 3-1 mainly includes a body 3-100, a sensing module 3-200, a control module 3-300, and a vibration module 3-400.
[0117] As Figure 22As shown, the body 3-100 can be used as the housing of the feedback system 3-1, for example, and the sensing module 3-200, the control module 3-300, and the vibration module 3-400 can be disposed in the body 3-100 to protect the sensing module 3-200, the control module 3-300, and the vibration module 3-400. In some embodiments, the foregoing vibration module 1-100 or vibration module 2-200 can be used to replace the vibration module 3-400, depending on the design requirements. In some embodiments, the sensing module 3-200 can be used to sense the state of the body 3-100 and output a sensing signal 3-S corresponding to this state to the control module 3-300. For example, the sensing module 3-200 can include different sensing components such as an inertial sensing component 3-210, a depth sensing component 3-220, a light sensing component 3-230, etc., to sense various different states of the body 3-100 respectively. In some embodiments, the inertial sensing component 3-210 can include, for example, elements such as a gyroscope, an accelerometer, an angular velocity meter, or a gravity direction sensor, etc., to sense the inertial state of the body 3-100 and output an inertial signal 3-S1 (a part of the sensing signal 3-S).
[0118] In some embodiments, when using the inertial sensing component 3-210 to sense the inertia of the feedback system 3-1, the signal sensed by the inertial sensing component 3-210 can be processed first and then the inertial signal 3-S1 is output. For example, filtering can be performed for a specific frequency, for example, only allowing waves of frequencies that will be generated when the feedback system 3-1 is in a normal use state to pass through, while filtering out noises of other frequencies. In other embodiments, the influence of the feedback system 3-1 on the entire electronic device can be recorded, and then the noise can be eliminated according to the recorded influence. For example, a signal with the same amplitude and opposite direction can be applied to the signal caused by the influence of the feedback system 3-1 on the entire electronic device to remove the noise caused by this influence. In other embodiments, the influence of the surrounding environment on the feedback system 3-1 can be recorded first, and then the noise formed by this influence can be removed, depending on the design requirements.
[0119] The depth sensing component 3-220 can be used to sense the position change of the body 3-100 relative to the environment and output a position signal 3-S2 (a part of the sensing signal 3-S) according to this position change. For example, Figure 23 is a schematic diagram of the feedback system 3-1 and the sensing device 3-2 in some embodiments of the present disclosure. As Figure 23As shown, the relative position between the feedback system 3-1 and the sensing device 3-2 can be sensed by a sensing device 3-2 external to the feedback system 3-1. For example, the distance L between the feedback system 3-1 and the sensing device 3-2, or the angle 3-θ between the line connecting the feedback system 3-1 and the sensing device 3-2 and the horizontal plane, etc. From this, information such as the position change or moving speed of the feedback system 3-1 relative to the environment can be calculated, and then a position signal 3-S2 is output. In some embodiments, the light sensing component 3-230 may include, for example, an optical sensor, which can be used to sense the light change in the surrounding environment of the body 3-100, and can output a light signal 3-S3 (a part of the sensing signal 3-S) corresponding to the light change in this environment.
[0120] By integrating the inertial signal 3-S1, the position signal 3-S2, and the light signal 3-S3, the sensing signal 3-S can be obtained, and the sensing module 3-200 provides this sensing signal 3-S to the control module 3-300 for further control of the feedback system 3-1. The control module 3-300 may include, for example, a central processing unit (CPU), which can process the received sensing signal 3-S to output a driving signal 3-D to the vibration module 3-400, thereby controlling the vibration module 3-400 to generate a vibration force on the body 3-100.
[0121] In some embodiments, the control module 3-300 may further include a memory, such as a read-only memory (ROM), a random access memory (RAM), etc., for storing data used to calibrate the sensing signal 3-S. For example, the inertial sensing calibration data 3-310, the depth sensing calibration data 3-320, and the light sensing calibration data 3-330 may be stored in the control module 3-300. The inertial sensing calibration data 3-310 can be used to record the calibration information of the inertial sensing component 3-210, the depth sensing calibration data 3-320 can be used to record the calibration information of the depth sensing component 3-220, and the light sensing calibration data 3-330 can be used to record the calibration information of the light sensing component 3-230. Thus, according to the inertial sensing calibration data 3-310, the depth sensing calibration data 3-320, and the light sensing calibration data 3-330 stored in the control module 3-300, the sensing signal 3-S can be processed and then the driving signal 3-D is output to the vibration module 3-400.
[0122] In some embodiments, when the feedback system 3-1 is used for the first time, the inertial sensing calibration data 3-310 and the light sensing calibration data 3-330 may not need to be recalibrated, but the depth sensing calibration data 3-320 must be recalibrated to obtain the position of the feedback system 3-1 relative to the environment. In some embodiments, the inertial sensing calibration data 3-310 and the light sensing calibration data 3-330 may also be recalibrated when the feedback system 3-1 is used for the first time to obtain more accurate information.
[0123] In some embodiments, the vibration module 3-400 may include a first vibration mechanism 3-410, a second vibration mechanism 3-420, and a third vibration mechanism 3-430. However, the present disclosure is not limited thereto, and the number of vibration mechanisms in the vibration module 3-400 can be adjusted according to requirements. The first vibration mechanism 3-410, the second vibration mechanism 3-420, and the third vibration mechanism 3-430 can be, for example, vibration motors or other mechanisms that can provide a vibration force to the main body 3-100.
[0124] Vibration forces can be provided to the main body 3-100 at different positions. For example, the first vibration mechanism 3-410 can generate a first vibration force at the first vibration position of the main body 3-100, the second vibration mechanism 3-420 can generate a second vibration force at the second vibration position of the main body 3-100, and the third vibration mechanism 3-430 can generate a third vibration force at the third vibration position of the main body 3-100. It should be noted that the shortest distances between the first vibration position, the second vibration position, and the third vibration position are all not equal to zero (e.g., greater than zero), that is, the positions where the first vibration mechanism 3-410, the second vibration mechanism 3-420, and the third vibration mechanism 3-430 apply forces to the main body 3-100 are separated from each other. Thus, different feedback forces (forces exerted by the main body 3-100 on the user) can be generated.
[0125] Figure 24 is a schematic diagram of the vibration mechanism in some embodiments of the present disclosure. In some embodiments, as Figure 24As shown, the first vibration mechanism 3-410 may include a fixed part 3-411, a movable part 3-412, an elastic element 3-413, and a driving component 3-414. The fixed part 3-411 may be fixed to the main body 3-100, while the movable part 3-412, the elastic element 3-413, and the driving component 3-414 may be disposed in the fixed part 3-411. The movable part 3-412 may include a relatively heavy element (such as a metal block) and may move relative to the fixed part 3-411. The elastic element 3-413 may be a spring, for example, having flexibility and elasticity, and the movable part 3-412 is movably connected to the fixed part 3-411 via the elastic element 3-413 to allow the movable part 3-412 to move relative to the fixed part 3-411. The driving component 3-414 may be disposed on the fixed part 3-411 and the movable part 3-412 to drive the movable part 3-412 to move relative to the fixed part 3-411.
[0126] In some embodiments, the driving component 3-414 may include an electromagnetic driving component (such as a combination of a magnet and a coil), which generates a driving force on the movable part 3-412 using the electromagnetic principle, thereby driving the movable part 3-412. In this embodiment, the driving component 3-414 may have a plurality of parts that are respectively disposed on the fixed part 3-411 and the movable part 3-412 and are separated from each other.
[0127] However, the present disclosure is not limited thereto. In some embodiments, the driving component 3-414 may also include a Shape Memory Alloy (SMA) driving component, which may deform according to temperature changes, thereby generating a driving force on the movable part 3-412 using the characteristics of shape memory alloy.
[0128] Alternatively, in some embodiments, the driving component 3-414 may also include a piezoelectric driving component, which can convert electrical energy into mechanical energy to generate a driving force on the movable part 3-412 using the piezoelectric principle. In this embodiment, the driving component 3-414 may connect the fixed part 3-411 and the movable part 3-412.
[0129] Although Figure 24 only the first vibration mechanism 3-410 is shown, it should be understood that the second vibration mechanism 3-420 and the third vibration mechanism 3-430 may also have a structure similar to that of the first vibration mechanism 3-410, which will not be elaborated herein.
[0130] In some embodiments, the first vibration mechanism 3-410, the second vibration mechanism 3-420, and the third vibration mechanism 3-430 may further include vibration mechanisms that can vibrate in multiple dimensions. For example, in some embodiments, the first vibration mechanism 3-410, the second vibration mechanism 3-420, or the third vibration mechanism 3-430 may include a first-dimension vibration mechanism, a second-dimension vibration mechanism, a third-dimension vibration mechanism, a fourth-dimension vibration mechanism, a fifth-dimension vibration mechanism, and a sixth-dimension vibration mechanism (not shown).
[0131] In some embodiments, the first-dimension vibration mechanism may generate vibrations in the first dimension, the second-dimension vibration mechanism may generate vibrations in the second dimension, the third-dimension vibration mechanism may generate vibrations in the third dimension, the fourth-dimension vibration mechanism may generate vibrations in the fourth dimension, the fifth-dimension vibration mechanism may generate vibrations in the fifth dimension, and the sixth-dimension vibration mechanism may generate vibrations in the sixth dimension. Among them, the first dimension, the second dimension, the third dimension, the fourth dimension, the fifth dimension, and the sixth dimension may be different from each other to allow the vibration module 3-400 to provide various different vibrations.
[0132] In some embodiments, the vibration in the first dimension may be a linear motion along the first direction (for example, the X direction), the vibration in the second dimension may be a linear motion along the second direction (for example, the Y direction), the vibration in the third dimension may be a linear motion along the third direction (for example, the Z direction), the vibration in the fourth dimension may be a rotation around the first direction as the axis, the vibration in the fifth dimension may be a rotation around the second direction as the axis, and the vibration in the sixth dimension may be a rotation around the third direction as the axis. Thus, the variability of the first vibration force, the second vibration force, and the third vibration force can be increased to provide the user with more diverse feedback. For example, multi-dimensional combined vibrations can be achieved, or the vibration in a single mode can also be amplified.
[0133] In some embodiments, the first-dimension vibration mechanism, the second-dimension vibration mechanism, the third-dimension vibration mechanism, the fourth-dimension vibration mechanism, the fifth-dimension vibration mechanism, and the sixth-dimension vibration mechanism may be separate multiple vibration mechanisms to more easily control each vibration mechanism. Alternatively, a single vibration mechanism can also provide vibrations in multiple dimensions. For example, the first-dimension vibration mechanism and the second-dimension vibration mechanism can be integrated into a single vibration mechanism to provide vibrations in two or more dimensions, so as to reduce the number of components used and achieve miniaturization.
[0134] When using an electronic product with a feedback system 3-1, even if the internal parameters have been set during manufacturing, it is very likely that the internal settings of the electronic product will change due to various factors during user operation. For example, environmental changes, impacts, data inside the electronic product disappearing or being rewritten due to surges or power outages, or component aging of the electronic product, etc., may cause the measured values to lose accuracy. Therefore, a calibration procedure 3-500 can be performed on the feedback system 3-1 to increase the reliability when using the electronic product with the feedback system 3-1.
[0135] Figure 25 is a flowchart of the calibration procedure 3-500 of some embodiments of the present disclosure. As Figure 25 shown, the calibration procedure 3-500 includes a first calibration procedure 3-510 for calibrating the inertial sensing calibration data 3-310, a second calibration procedure 3-520 for calibrating the depth sensing calibration data 3-320, and a third calibration procedure 3-530 for calibrating the light sensing calibration data 3-330.
[0136] Although in Figure 25 the first calibration procedure 3-510, the second calibration procedure 3-520, and the third calibration procedure 3-530 are shown to be performed in sequence, the present disclosure is not limited thereto. For example, the order of the first calibration procedure 3-510, the second calibration procedure 3-520, and the third calibration procedure 3-530 can be changed according to requirements, or specific calibration procedures can be performed simultaneously, depending on the design requirements.
[0137] The first calibration procedure 3-510 may include various ways to redefine the inertial sensing calibration data 3-310. For example, the body 3-100 can be stationary to redefine the inertial sensing calibration data 3-310. In some embodiments, the position signal 3-S2 measured by the depth sensing component 3-220 can be referred to, and the inertial sensing calibration data 3-310 can be redefined by comparing the position changes of the environment. In some embodiments, the accelerometer and the angular velocity sensor (not shown) in the inertial sensing component 3-210 can be used to redefine the inertial sensing calibration data 3-310.
[0138] For example, an acceleration sensor can be used to sense the acceleration of the entire feedback system 3-1, and then compared with the acceleration due to gravity. If the acceleration measured by the acceleration sensor is different from the acceleration due to gravity, it means that the feedback system 3-1 is in motion rather than at rest. For example, in some embodiments, the absolute value of the acceleration A sensed by the acceleration sensor needs to be within the sum of the acceleration due to gravity G and the acceleration sensing error value E1, that is, |A| < G + E1. When this state persists for more than a preset time T, an angular velocity sensor can be further used to redefine the inertial sensing calibration data 3-310 to obtain a more accurate value.
[0139] The appropriate acceleration sensing error value E1 can be selected according to requirements. For example, an external device (not shown) can be used to measure the feedback system 3-1, thereby determining the acceleration sensing error value E1 and recording it in the inertial sensing calibration data 3-310 of the control module 3-300. Alternatively, the body 3-100 can be left stationary for a period of time and then an external device can be used to measure the feedback system 3-1, thereby determining the acceleration sensing error value E1 and recording it in the inertial sensing calibration data 3-310 of the control module 3-300 to obtain a more accurate acceleration sensing error value E1.
[0140] If the measured acceleration A is approximately the same as the acceleration due to gravity G, it can be further determined whether the angular velocity N of the entire feedback system 3-1 measured by the angular velocity sensor is 0. For example, in some embodiments, the absolute value of the angular velocity N sensed by the angular velocity sensor needs to be less than an angular velocity sensing error value E2, that is, |N| < E2. When this state persists for more than the preset time T, it can be determined that the feedback system 3-1 is in a stationary state, and then the inertial sensing calibration data 3-310 is redefined. In some embodiments, the acceleration sensor and the angular velocity sensor can be used sequentially to sense the state change of the feedback system 3-1, or the acceleration sensor and the angular velocity sensor can be used simultaneously to sense the state change of the feedback system 3-1, depending on the design requirements.
[0141] The second calibration procedure 3-520 can include various ways to redefine the depth sensing calibration data 3-320. For example, in the second calibration procedure 3-520, the body 3-100 can be placed at multiple different positions to redefine the depth sensing calibration data 3-320. In some embodiments, the depth sensing calibration data 3-320 can be redefined by referring to the inertial signal 3-S1 and through the inertial state of the body 3-100. In some embodiments, the first calibration procedure 3-510 and the second calibration procedure 3-520 can be performed simultaneously.
[0142] The third calibration procedure 3-530 can be used to redefine the light sensing calibration data 3-330. For example, an external device (not shown) can be used to emit a reference light to the light sensing component 3-230 to redefine the light sensing calibration data 3-330.
[0143] By performing the foregoing calibration procedure 3-500, the inertial sensing calibration data 3-310, the depth sensing calibration data 3-320, and the light sensing calibration data 3-330 can be redefined to better conform to the actual situation, thereby increasing the accuracy when the feedback system 3-1 is used. In some embodiments, only some of the operations in the foregoing calibration procedure 3-500 can be performed to simplify the calibration procedure 3-500. Alternatively, all of the operations in the foregoing calibration procedure 3-500 can also be performed to obtain more accurate information. In some embodiments, the calibration procedure 3-500 can be repeated multiple times under the condition that the feedback system 3-1 has different postures (such as changing positions), and then compared with each other to obtain more accurate calibration data.
[0144] When the feedback system 3-1 is used, the feedback system 3-1 can have multiple feedback modes to provide different feedback forces to the user. For example, the feedback system 3-1 can include a first feedback mode, a second feedback mode, and a third feedback mode. The first feedback mode is used to generate a first feedback force on the body 3-100, the second feedback mode is used to generate a second feedback force on the body 3-100, and the third feedback mode is used to generate a third feedback force on the body 3-100 and provide the above feedback forces to the user.
[0145] In some embodiments, the first feedback force, the second feedback force, and the third feedback force are different from each other. For example, the directions and magnitudes of the first feedback force and the second feedback force are both different, and the directions of the first feedback force and the third feedback force can be the same as each other, but have different magnitudes, depending on the design requirements. In other words, the first feedback force and the third feedback force can have the same pattern, but have different amplitudes. Thus, different first feedback force, second feedback force, and third feedback force can be provided to the user, and different information can be transmitted thereby.
[0146] For example, different first feedback modes, second feedback modes, and third feedback modes can be performed by changing the magnitudes or dimensions of the first vibration force, the second vibration force, and the third vibration force applied to the main body 3-100 by the first vibration mechanism 3-410, the second vibration mechanism 3-420, and the third vibration mechanism 3-430, respectively. For example, in the first feedback mode, the magnitudes and dimensions of the first vibration force, the second vibration force, and the third vibration force may all be the same as each other. Next, in the second feedback mode, the magnitudes and dimensions of the first vibration force, the second vibration force, and the third vibration force may all be different from each other. In the third feedback mode, the magnitudes of the first vibration force, the second vibration force, and the third vibration force may be different from each other, and the dimensions of the first vibration force, the second vibration force, and the third vibration force may all be the same as each other. Thus, different feedback forces can be provided to the user, thereby conveying different information. In some embodiments, the control module 3-300 can determine to use the first feedback mode, the second feedback mode, or the third feedback mode for feedback according to the received sensing signal 3-S, so as to provide different information to the user for different environments.
[0147] In some embodiments, in order to reduce the overall size of the feedback system 3-1, the resonance method can be used to amplify the vibration effect of the vibration module 3-400. When the vibration force is applied at the resonance frequency of the feedback system 3-1, compared with when the same vibration force is applied at other non-resonance frequencies, the feedback system 3-1 will resonate, so as to vibrate with a higher amplitude to enhance the force feedback to the user. Generally speaking, there are multiple resonance frequencies in a system, and the system is more likely to resonate at these frequencies. For example, a preset information can be written in the control module 3-300, which may include a first frequency and a second frequency. The first frequency can record the first resonance frequency of the overall feedback system 3-1, which may not be the first natural resonance frequency (the resonance frequency with the lowest frequency) of the feedback system 3-1, and the second frequency can record the second resonance frequency of the overall feedback system 3-1, and the first frequency is different from the second frequency. In some embodiments, the vibration frequency of the first feedback force is the same as the vibration frequency of the first resonance frequency, the vibration frequency of the second feedback force is the same as the vibration frequency of the second resonance frequency, and the vibration frequency of the third feedback force is the same as the vibration frequency of the first resonance frequency. Thus, vibration can be performed by the resonance method to reduce the size of the required vibration module 3-400, so as to achieve miniaturization.
[0148] In some embodiments, the resonance frequency F1 of the body 3-100 may be close to the resonance frequency F2 of the overall combination of the moving part (such as the moving part 3-412) and the elastic element (such as the elastic element 3-413) in the first vibration mechanism 3-410, the second vibration mechanism 3-420, or the third vibration mechanism 3-430. For example, the difference between the resonance frequency F1 and the resonance frequency F2 may be less than 10% of the resonance frequency F1, that is, |F1 - F2| / F1 < 0.1. Thus, resonance can be more easily achieved.
[0149] However, it should be noted that when designing the feedback system 3-1, the first vibration position where the first vibration mechanism 3-410 applies the first vibration force to the body 3-100, the second vibration position where the second vibration mechanism 3-420 applies the second vibration force to the body 3-100, and the third vibration position where the third vibration mechanism 3-430 applies the third vibration force to the body 3-100 are designed to avoid being on the nodes of the first vibration mode or the second vibration mode of the body 100, so as to avoid exciting other vibration modes. The first vibration mode and the second vibration mode may be, for example, the vibration modes when the body 100 generates standing waves.
[0150] Figure 26 It is a schematic diagram when standing waves occur in the body 3-100. As Figure 26 shown, in the same medium, when two waves 3-600A and 3-600B with opposite propagation directions, the same amplitude, and the same frequency meet, standing waves (such as the first vibration mode or the second vibration mode) will be formed, and nodes 3-610 (i.e., vibration weakening points) and antinodes 3-620 (i.e., vibration strengthening points) will be generated at a series of fixed positions on the body 100. At the nodes 3-610, the amplitude is zero. At the antinodes 3-620, the amplitude is the largest. In some embodiments, the first vibration position can be set at the antinode 3-620 of the first vibration mode, the second vibration position can be set at the antinode 3-620 of the second vibration mode, and the third vibration position can be set at the antinode 3-620 of the first vibration mode to obtain the maximum vibration feedback effect.
[0151] The aforementioned feedback system 3-1 can be set in various devices with vibration functions. Figure 27 、 Figure 28 、 Figure 29A 、 Figure 29B It is a schematic diagram of some applications of the feedback system 3-1 in some embodiments of the present disclosure. For example, the feedback system 3-1 can be set on a vehicle device, such as it can be set on Figure 27In the shown steering wheel 3-3, when it is inconvenient for the driver to read the information on the screen, feedback is given to the driver in a vibrating manner. For example, the feedback system 3-1 can cooperate with the vehicle's reverse radar. If the vehicle is about to hit other objects when reversing, the feedback system 3-1 can vibrate to notify the driver. Or, different modes of vibration feedback can be provided when the vehicle is at different distances from the object to facilitate the driver's driving. Or, as Figure 28 shown, the feedback system 3-1 can also be set in the car key 3-4 to vibrate when the car key 3-4 approaches the vehicle, thereby informing the user of the vehicle's position.
[0152] In some embodiments, such as Figure 29A and Figure 29B shown, the feedback system 3-1 can be set in the smart bracelet 3-5 to give feedback on the user's physical condition. For example, the smart bracelet 3-5 can also include a communication module 3-6. If the user wearing the smart bracelet 3-5 falls (with an excessive acceleration instantaneously) and there is no change in any posture within a specific time afterwards, the feedback system 3-1 senses the user's physical state (such as heart rate, etc.) and processes it. If it is determined that the user is in danger, a warning is generated for the user through the feedback system 3-1. If the user does not eliminate this warning, other people can be notified (such as reporting to the police) through the communication module 3-6 electrically connected to the feedback system 3-1 to ensure the safety of the user.
[0153] In summary, the present disclosure provides a feedback system, including a body, a vibration module, a sensing module, and a control module. The vibration module has a first vibration mechanism for generating a first vibration force on the body at a first vibration position. The sensing module is used to sense the state of the body and output a sensing signal. The control module is used to receive the sensing signal and output a driving signal to the first vibration module to generate a first vibration force. Thus, vibration feedback can be performed on the environmental information sensed by the sensing module to inform the user of specific information. In addition, the feedback system can vibrate through resonance, thereby reducing the volume of the required components and achieving miniaturization.
