In some embodiments, the optical system 1-100 may generally include a top housing 1-110, a base housing 1-120, a second movable portion 1-130, a first coil 1-140, a first magnetic element 1-150, a first elastic element 1-160, a second elastic element 1-170, a first substrate 1-200, a circuit assembly 1-210, a ninth coil element 1-318, a tenth coil element 1-328, a first movable portion 1-400, a first optical element 1-500, a filter element 1-510, a second substrate 1-600, an elastic assembly 1-700, and a first driving assembly 1-800 arranged along a major axis 1-O. The optical systems 1-100 may be disposed on an electronic device, such as a mobile phone, a tablet computer, a notebook computer, etc., but not limited thereto.

The optical system 1-100 may be used to drive the second optical element 1-900, or may also be used to drive various optical elements (such as lenses, mirrors, prisms, beam splitters, apertures, liquid lenses, image sensors, camera modules, and ranging modules). It should be noted that the definition of the optical element is not limited to the element related to visible light, and the element related to invisible light (such as infrared light, ultraviolet light) may be included in the present invention.

In some embodiments, the top case 1-110, the base 1-120, the second movable portion 1-130, the first coil 1-140, the first magnetic element 1-150, the first elastic element 1-160, and the second elastic element 1-170 may be collectively referred to as a first optical assembly 1-105 for driving the second optical element 1-900 to move in the direction X, Y, Z. In addition, the top case 1-110 and the bottom case 1-120 can be fixed on the first substrate 1-200, so the top case 1-110, the bottom case 1-120, and the first substrate 1-200 can be collectively referred to as a fixing portion 1-F. The first movable portion 1-400 and the second movable portion 1-130 are movable relative to the fixed portion 1-F. In some embodiments, the second movable portion 1-130 can also move relative to the first movable portion 1-400.

It should be understood that the top housing 1-110 and the base 1-120 are formed with a top housing opening and a base opening, respectively, the top housing opening having a center corresponding to the primary axis 1-O (e.g., the primary axis 1-O included in the fixing portion 1-F, wherein the top housing 1-110 and the base 1-120 may be arranged along the primary axis 1-O), the base opening corresponding to the first optical element 1-500, and the first optical element 1-500 may be disposed on the first substrate 1-200. Accordingly, the first optical element 1-500 may correspond to the second optical element 1-900, and may be arranged, for example, in the direction of the principal axis 1-O (e.g., the Z direction), such that the second optical element 1-900 may be in focus with the first optical element 1-500 in the direction of the principal axis 1-O.

In some embodiments, the second movable portion 1-130 has a through hole, and the second optical element 1-900 can be fixed in the through hole to move together with the movement of the second movable portion 1-130, i.e. the second movable portion 1-130 can be used to carry the second optical element 1-900. In some embodiments, the first magnetic elements 1-150 and the first coils 1-140 can be collectively referred to as a second driving assembly 1-D2 for driving the second movable portion 1-130 to move relative to the fixed portion 1-F.

The first magnetic elements 1-150 and the first coils 1-140 can be located on the fixed portion 1-F and the second movable portion 1-130, respectively, or the positions can be interchanged, depending on the design requirements. It should be understood that through the action between the first magnetic element 1-150 and the first coil 1-140, a magnetic force can be generated to force the second optical element 1-900 disposed on the second movable portion 1-130 to move relative to the fixed portion 1-F, such as Auto Focus (AF) or optical hand shock prevention (OIS) effect can be achieved. In some embodiments, the second driving element 1-D2 may also include a piezoelectric element, a shape memory alloy, or other driving elements.

In the present embodiment, the second movable portion 1-130 and the second optical element 1-900 therein are movably (movably) disposed in the fixed portion 1-F. More specifically, the second movable portion 1-130 can be connected to the fixed portion 1-F through the first elastic element 1-160 and the second elastic element 1-170 made of metal material and suspended in the fixed portion 1-F. When the first coils 1-140 are energized, the first coils 1-140 will act on the magnetic field of the first magnetic elements 1-150 and generate an electromagnetic driving force (electromagnetic force) to drive the second movable portions 1-130 and the second optical elements 1-900 to move along the main axis 1-O direction relative to the fixed portion 1-F, so as to achieve the auto-focusing effect.

In some embodiments, a first sensing assembly 1-SE1 may also be provided in the optical system 1-100 for sensing the position of the second movable part 1-130 relative to the fixed part 1-F. The first sensing assembly 1-SE1 may include a first sensing element 1-SE11, a second sensing element 1-SE 12.

In some embodiments, other sensing elements may be provided to sense the position of the first movable portion 1-400 relative to the fixed portion 1-F, such as between the first substrate 1-200 and the first movable portion 1-400.

For example, the sensing component can be used to sense the movement of the first movable portion 1-400 or the second movable portion 1-130 relative to the fixed portion 1-F in different dimensions, such as the translation in the X direction (first dimension), the translation in the Y direction (second dimension), the translation in the Z direction (third dimension), the rotation with the Z axis as the rotation axis (fourth dimension), etc., but the present invention is not limited thereto.

The first substrate 1-200 is, for example, a flexible printed circuit board (FPC), which may be fixed to the base 1-120 by adhesion. In the present embodiment, the first substrate 1-200 is electrically connected to other electronic devices disposed inside or outside the optical system 1-100. For example, the first substrate 1-200 can transmit an electrical signal to the second driving assembly 1-D2, thereby controlling the movement of the second movable portion 1-130 in the X, Y or Z direction, and further realizing the functions of Auto Focus (AF) or optical hand vibration prevention (OIS).

In some embodiments, the circuit assembly 1-210 is, for example, a flexible printed circuit board (FPC), which may be adhesively secured to the fixing portion 1-F. In the present embodiment, the circuit elements 1-210 are electrically connected to other electronic devices or electronic apparatuses disposed inside or outside the optical device driving mechanisms 1-100. For example, the circuit component 1-210 can transmit the electrical signal of the electronic device to the first driving component 1-800, the first optical component 1-105, i.e. the first optical component 1-105 and the first driving component 1-800 are electrically connected to the electronic device through the circuit component 1-210, so as to control the movement of the first movable portion 1-400 in the X, Y or Z direction, thereby implementing the functions of Auto Focus (AF) or optical hand vibration prevention (OIS).

The ninth coil element 1-318 and the tenth coil element 1-328 may be disposed on the first movable part 1-400 and the fixed part 1-F, respectively. The ninth coil element 1-318, the first optical element 1-500 may be disposed on the circuit assembly 1-210, and the ninth coil element 1-318 may surround the first optical element 1-500. The tenth coil element 1-328 may wirelessly transmit various signals to the ninth coil element 1-318 (described later).

The top case 1-110 of the fixed part 1-F has a polygonal structure, and the first movable part 1-400 may have a plate-shaped structure and may be perpendicular to the main shaft 1-O. The material of the first movable portion 1-400 may include plastic to avoid magnetic interference. The first optical element 1-500 and the filter element 1-510 may be arranged (e.g. connected) on the first movable part 1-400, e.g. movable together with the first movable part 1-400 relative to the fixed part 1-F. The first optical element 1-500 may include a photoelectric converter, such as a photosensitive element, for corresponding to and sensing the light passing through the second optical element 1-900, converting the light into an electrical signal, and providing the electrical signal to the electronic device. In some embodiments, the first movable portion 1-400 is movable relative to the fixed portion 1-F. Therefore, the first optical element 1-500 disposed on the first movable portion 1-400 is also moved by the first movable portion 1-400, thereby achieving an optical anti-shake (OIS) effect, for example. The first optical element 1-500 is used for receiving an optical signal and outputting an image signal.

In some embodiments, a first communication element 1-341 and a second communication element 1-342 may be provided in the optical system 1-100. The first communication element 1-341 may be fixed to the first movable part 1-400 and the second communication element 1-342 may be fixed to the fixed part 1-F, and the first communication element 1-341 and the second communication element 1-342 may be collectively referred to as a first communication assembly 1-340A. The video signal is output to an external circuit for communication via a first signal (wireless electromagnetic wave) transmitted by the first communication device 1-340A. For example, the optical systems 1-100 may be disposed on an electronic device (e.g., a mobile phone, a tablet computer, a notebook computer, etc.), and the external circuit is an external circuit of the electronic device.

In some embodiments, the first communication element 1-341 and the second communication element 1-342 have a spacing greater than zero, i.e., the first communication element 1-341 and the second communication element 1-342 are not connected via wires and are thus electrically independent. For example, the first signal may be transmitted wirelessly from the first communication element 1-341 to the second communication element 1-342 or from the second communication element 1-342 to the first communication element 1-341. The second communication elements 1-342 can be electrically connected to the external circuit of the electronic device. The first communication elements 1-341 and the second communication elements 1-342 may comprise, for example, a first integrated circuit element and a second integrated circuit element, respectively, for transmitting signals. The first communication components 1-340A may include, for example, Bluetooth (Bluetooth), Wireless Local Area Network (WLAN), Wireless Wide Area Network (WWAN), etc., depending on design requirements.

The filter elements 1-510 may only allow light of a specific wavelength to pass through and filter out other light having unwanted wavelengths, i.e., may filter electromagnetic waves of a specific wavelength. For example, the filter elements 1-510 can filter infrared light and allow visible light to pass through, but not limited thereto. The filter elements 1-510 may correspond to the first optical elements 1-500. Therefore, the light rays sensed by the first optical elements 1-500 can be closer to the naked eyes.

The second substrate 1-600 may be disposed on the first movable portion 1-400, the elastic member 1-700 may be used to movably connect the second substrate 1-600 with the fixed portion 1-F (e.g., the base 1-120), and the first driving member 1-800 may be used to drive the first movable portion 1-400 to move relative to the fixed portion 1-F or relative to the second movable portion 1-130.

In some embodiments, the first driving assembly 1-800 may be used to drive the first movable portion 1-400 to move relative to the fixed portion 1-F. In some embodiments, the material of the drive element of the first drive assembly 1-800 may comprise Shape Memory Alloy (SMA) and have an elongated Shape and extend in one direction. The shape memory alloy is an alloy material which can completely eliminate the deformation of the shape memory alloy at a lower temperature after being heated and recover the original shape of the shape memory alloy before the deformation. For example, after a finite amount of plastic deformation of the shape memory alloy below the transformation temperature, the shape memory alloy can be heated to return to its original shape prior to the deformation.

The elastic member 1-700 may be movably coupled to the second base plate 1-600 by the first driving member 1-800. When the driving element in the first driving assembly 1-800 is deformed, the second substrate 1-600 and the elastic assembly 1-700 are driven to move relatively, so that the first movable portion 1-400 is allowed to move relative to the fixed portion 1-F, and the first optical element 1-500 arranged on the first movable portion 1-400 is moved together, thereby achieving the effect of optical anti-shake.

Fig. 5A is a schematic diagram of some elements of optical system 1-100A. The elements of the optical system 1-100A may be substantially similar to the optical system 1-100 described above, and only some of the elements are shown in FIG. 5A. The top shells 1-110 of the anchors 1-F may include a first side 1-S1, a second side 1-S2, a third side 1-S3, and a fourth side 1-S4, as viewed along the direction of the major axis 1-O (Z direction), wherein the second side 1-S2 is not parallel to the first side 1-S1, the third side 1-S3 is parallel to the first side 1-S1, and the fourth side 1-S4 is parallel to the second side 1-S2. In addition, the top case 1-110 also includes the first corner 1-C1, second corner 1-C2, third corner 1-C3, fourth corner 1-C4. First corner 1-C1 is located between fourth side 1-S4 and first side 1-S1, second corner 1-C2 is located between first side 1-S1 and second side 1-S2, third corner 1-C3 is located between second side 1-S2 and third side 1-S3, and fourth corner 1-C4 is located between third side 1-S3 and fourth side 1-S4.

The ninth 1-318 and tenth 1-328 coil elements may be arranged to surround the first optical element 1-500, seen along the main axis 1-O, but not to overlap the first optical element 1-500, in order to avoid magnetic interference. The spindle 1-O may pass through the ninth coil element 1-318 and the tenth coil element 1-328. Further, the ninth coil element 1-318 may overlap the tenth coil element 1-328 to provide signals from the tenth coil element 1-328 to the ninth coil element 1-318 by way of electromagnetic induction.

However, the present invention is not limited thereto. For example, FIG. 5B is a schematic diagram of some elements of the optical system 1-100B. The elements of the optical system 1-100B may be substantially similar to the optical system 1-100, and only some of the elements are shown in FIG. 5B. In fig. 5B, the optical system 1-100B may further include a first coil element 1-310, a second coil element 1-320, a third coil element 1-312, a fourth coil element 1-322, a fifth coil element 1-314, a sixth coil element 1-324, a seventh coil element 1-316, and an eighth coil element 1-326 in addition to the ninth coil element 1-318 and the tenth coil element 1-328. The first coil element 1-310 corresponds to the second coil element 1-320, the third coil element 1-312 corresponds to the fourth coil element 1-322, the fifth coil element 1-314 corresponds to the sixth coil element 1-324, the seventh coil element 1-316 corresponds to the eighth coil element 1-326, and the ninth coil element 1-318 corresponds to the tenth coil element 1-328.

For example, the first coil element 1-310 and the second coil element 1-320 at least partially overlap, the third coil element 1-312 and the fourth coil element 1-322 at least partially overlap, the fifth coil element 1-314 and the sixth coil element 1-324 at least partially overlap, the seventh coil element 1-316 and the eighth coil element 1-326 at least partially overlap, and the ninth coil element 1-318 and the tenth coil element 1-328 at least partially overlap, as viewed along the winding axis of each coil element.

In some embodiments, first coil element 1-310, third coil element 1-312, fifth coil element 1-314, seventh coil element 1-316, and ninth coil element 1-318 may be collectively referred to as a first coil assembly 1-W1 (or third communication element 1-343), and second coil element 1-320, fourth coil element 1-322, sixth coil element 1-324, eighth coil element 1-326, and tenth coil element 1-328 may be collectively referred to as a second coil assembly 1-W2 (or fourth communication element 1-344). The third communication element 1-343 and the fourth communication element 1-344 may be collectively referred to as a second communication assembly 1-340B. The first communication component 1-340A and the second communication component 1-340B can form a communication module 1-340 for connecting with external circuits.

Furthermore, the first optical element 1-500 does not at least partially overlap the first coil assembly 1-W1 or the second coil assembly 1-W2, viewed in the direction of the main axis 1-O (Z-direction), in order to avoid magnetic interference. And the first coil assembly 1-W1 at least partially overlaps the second coil assembly 1-W2 to transmit signals by way of electromagnetic induction.

Viewed along the direction of the main axis 1-O, the first coil element 1-310, the second coil element 1-320, the third coil element 1-312, the fourth coil element 1-322 are located at the first side 1-S1, the third coil element 1-312, the fourth coil element 1-322, the fifth coil element 1-314, the sixth coil element 1-324 are located at the second side 1-S2, the fifth coil element 1-314, the sixth coil element 1-324, the seventh coil element 1-316, the eighth coil element 1-326 are located at the third side 1-S3, and the first coil element 1-310, the second coil element 1-320, the seventh coil element 1-316, the eighth coil element 1-326 are located at the fourth side 1-S4. Further, the first coil element 1-310, the second coil element 1-320 are located at the first corner 1-C1, the third coil element 1-312, the fourth coil element 1-322 are located at the second corner 1-C2, the fifth coil element 1-314, the sixth coil element 1-324 are located at the third corner 1-C3, the seventh coil element 1-316, the eighth coil element 1-326 are located at the fourth corner 1-C4. For example, the first coil element 1-310, the second coil element 1-320, and the third coil element 1-312, the fourth coil element 1-322, the fifth coil element 1-314, the sixth coil element 1-324, the seventh coil element 1-316, and the eighth coil element 1-326 do not overlap (i.e., the first coil assembly 1-W1 and the second coil assembly 1-W2 do not at least partially overlap). Therefore, magnetic interference among the coils can be avoided.

The second coil assembly 1-W2 (the fourth pass cell 1-344) can be used to transmit a power signal to the first coil assembly 1-W1 (the third pass cell 1-343) in a wireless manner, i.e. the power signal transmitted by the external circuit via the second communication assembly 1-340B is input to the first optical assembly 1-105, so as to achieve the technical effect of wireless charging. For example, when an alternating current signal is provided to the second coil assembly 1-W2, the first coil assembly 1-W1 generates an induced electromotive force (induced electromotive force) accordingly, so that the power signal can be wirelessly transmitted to the first coil assembly 1-W1.

Alternatively, an additional magnetic element, such as a magnet or a ferromagnetic material (e.g., iron, cobalt, nickel, etc.), may be disposed on the first movable portion 1-400, and when a dc signal is provided to the second coil assembly 1-W2, the second coil assembly 1-W2 may act as an electromagnet and generate an electromagnetic driving force with the magnetic element on the first movable portion 1-400 to drive the first movable portion 1-400 to move relative to the fixed portion 1-F. In this case, the thrust force required to be generated by the first driving unit 1-800 can be reduced, and the first driving unit 1-800 having a smaller size can be used, or the first driving unit 1-800 can be omitted to achieve miniaturization.

In addition, a first supporting member 1-360 and a second supporting member 1-370 may be further disposed between the first movable portion 1-400 and the fixed portion 1-F (e.g., the first substrate 1-200). The first support assembly 1-360 may include a spherical first support element 1-362, a second support element 1-364, and a third support element 1-366. Second support assembly 1-370 may include a fourth support element 1-372, a fifth support element 1-374, and a sixth support element 1-376 that are spherical in shape. The first supporting member 1-362, the second supporting member 1-364, the third supporting member 1-366, the fourth supporting member 1-372, the fifth supporting member 1-374 and the sixth supporting member 1-376 may be located at a side or a corner of the first movable portion 1-400 or the top case 1-110 to restrict the position of the first movable portion 1-400 with respect to the fixed portion 1-F.

In some embodiments, the first support element 1-362, the second support element 1-364, and the third support element 1-366 can have substantially the same diameter, the fourth support element 1-372, the fifth support element 1-374, and the sixth support element 1-376 can also have substantially the same diameter, and the diameters of the first support element 1-362, the second support element 1-364, and the third support element 1-366 can be different from the diameters of the fourth support element 1-372, the fifth support element 1-374, and the sixth support element 1-376.

For example, the diameters of the first support element 1-362, the second support element 1-364, and the third support element 1-366 are larger than the diameters of the fourth support element 1-372, the fifth support element 1-374, and the sixth support element 1-376. Therefore, in the resting state, the first supporting member 1-362, the second supporting member 1-364, and the third supporting member 1-366 can directly contact the first movable portion 1-400 and the fixed portion 1-F, while the fourth supporting member 1-372, the fifth supporting member 1-374, and the sixth supporting member 1-376 directly contact only the fixed portion 1-F and are spaced apart from the first movable portion 1-400. That is, the first movable portion 1-400 can be connected to the fixed portion 1-F through the first supporting member 1-360.

When viewed in the direction of the major axis 1-O, as shown by the dashed lines in FIG. 5B, the first support element 1-362, the second support element 1-364, and the third support element 1-366 form a first triangular structure 1-368, and the first triangular structure 1-368 does not overlap with the fourth support element 1-372, the fifth support element 1-374, and the sixth support element 1-376. In addition, the fourth support element 1-372, the fifth support element 1-374 and the sixth support element 1-376 form a second triangular structure 1-378, and the second triangular structure 1-378 does not overlap with the first support element 1-362, the second support element 1-364 and the third support element 1-366. When the first movable portion 1-400 is impacted, the rotation axis formed by the connection line of any two of the first supporting element 1-362, the second supporting element 1-364, and the third supporting element 1-366 may rotate. For example, when the first movable portion 1-400 can rotate through the rotation axis formed by the connection line of the first supporting element 1-362 and the second supporting element 1-364. In this state, by the aforementioned positional relationship (the first triangular structure 1-368 is not overlapped with the fifth support member 1-374), the fifth support member 1-374 can serve as a stopper structure to limit the maximum rotatable range of the first movable portion 1-400, thereby preventing the first movable portion 1-400 from colliding with other members.

In the following embodiments, the first supporting elements 1 to 360 and the second supporting elements 1 to 370 in the present embodiment may also be disposed, and the first supporting elements 1 to 360 and the second supporting elements 1 to 370 are omitted in the following description for brevity.

Fig. 5C is a schematic diagram of some elements of the optical system 1-100C. The elements of the optical system 1-100C may be substantially similar to the optical system 1-100 described above, and only some of the elements are shown in FIG. 5C. In fig. 5C, the aforementioned ninth coil element 1-318 and tenth coil element 1-328 may be omitted. Further, the first coil element 1-310, the third coil element 1-312, the fifth coil element 1-314, and the seventh coil element 1-316 may have different sizes from the second coil element 1-320, the fourth coil element 1-322, the sixth coil element 1-324, and the eighth coil element 1-326.

For example, the dimensions of the first coil element 1-310, the third coil element 1-312, the fifth coil element 1-314, the seventh coil element 1-316 may be smaller than the dimensions of the second coil element 1-320, the fourth coil element 1-322, the sixth coil element 1-324, the eighth coil element 1-326, i.e. the first coil component 1-W1 does not completely overlap the second coil component 1-W2, but is partially exposed to the second coil component 1-W2, as seen in the direction of the main axis 1-O. Therefore, the size of each coil on the first movable portion 1-400 can be reduced, and miniaturization can be achieved.

Although the coil elements in the foregoing embodiments are disposed at the corners of the top cases 1 to 110, the present invention is not limited thereto. For example, FIG. 5D is a schematic diagram of some elements of the optical system 1-100D. The elements of the optical system 1-100D may be substantially similar to the optical system 1-100 described above, and only some of the elements are shown in FIG. 5D.

In fig. 5D, there are further included eleventh and twelfth coil elements 1-311 and 1-321 disposed at the first side 1-S1, and thirteenth and fourteenth coil elements 1-315 and 1-325 disposed at the third side 1-S3. The eleventh and thirteenth coil elements 1-311, 1-315 may be part of a first coil assembly 1-W1, while the twelfth and fourteenth coil elements 1-321, 325 may be part of a second coil assembly 1-W2. The eleventh and thirteenth coil elements 1-311 and 1-315 of the first coil block 1-W1 may be provided on the first movable part 1-400, and the twelfth and fourteenth coil elements 1-321 and 1-325 of the second coil block 1-W2 may be provided on the fixed part 1-F.

By providing additional eleventh, twelfth, thirteenth, and fourteenth coil elements 1-311, 1-321, 1-315, and 1-325 at the side edges, the maximum power of the signal transmitted to the first coil assembly 1-W1 by the second coil assembly 1-W2 can be increased to improve the transmission effect. In addition, the coil elements are arranged at the side edges, and the space of the side edges can be further utilized, so that the miniaturization is realized.

Fig. 6A, 6B are schematic side views of the optical systems 1-100D as viewed from different directions, with only some of the elements shown for clarity. As shown in fig. 6A, 6B, in the Z direction, the fifth coil element 1-314 may be aligned with the sixth coil element 1-324, the seventh coil element 1-316 may be aligned with the eighth coil element 1-326, and the thirteenth coil element 1-315 may be aligned with the fourteenth coil element 1-325.

Fig. 5E is a schematic diagram of some elements of optical system 1-100E. The elements of the optical system 1-100E may be substantially similar to the optical system 1-100 described above, and only some of the elements are shown in FIG. 5E. In fig. 5E, the distance between the first coil element 1-310, the eleventh coil element 1-311, the third coil element 1-312 may be different from the distance between the second coil element 1-320, the twelfth coil element 1-321, the fourth coil element 1-322 in the X direction.

For example, in the X-direction (first direction), the distance 1-L1 between the center 1-310C of the first coil element 1-310 and the center 1-312C of the third coil element 1-312 is different from the distance 1-L2 between the center 1-320C of the second coil element 1-320 and the center 1-322C of the fourth coil element 1-322, e.g., the distance 1-L1 may be smaller than the distance 1-L2, and the eleventh coil element 1-311 may overlap the twelfth coil element 1-321. The fifth coil elements 1-314, the sixth coil elements 1-324, the seventh coil elements 1-316, the eighth coil elements 1-326, the thirteenth coil elements 1-315, and the fourteenth coil elements 1-325 may have similar positional relationships, and will not be described herein again.

Further, in the Y direction (second direction), the first coil element 1-310, the eleventh coil element 1-311, the third coil element 1-312, the second coil element 1-320, the twelfth coil element 1-321, the fourth coil element 1-322 may be aligned with the seventh coil element 1-316, the eighth coil element 1-326, the thirteenth coil element 315, the fourteenth coil element 325, the fifth coil element 1-314, the sixth coil element 1-324, respectively, to provide more uniform charging power.

FIG. 6C is a side view schematic of optical systems 1-100E, with only some of the elements shown for clarity. As shown in FIG. 6C, in the Z direction, the thirteenth coil element 1-315 may be aligned with the fourteenth coil element 1-325, while the fifth coil element 1-314 may be misaligned with the sixth coil element 1-324 and the seventh coil element 1-316 may be misaligned with the eighth coil element 1-326. In the X-direction (first direction), the distance 1-L1 between the center 1-310C of the first coil element 1-310 and the center 1-312C of the third coil element 1-312 is different from the distance 1-L2 between the center 1-320C of the second coil element 1-320 and the center 1-322C of the fourth coil element 1-322, e.g. the distance 1-L1 may be smaller than the distance 1-L2.

Fig. 5F is a schematic diagram of some elements of the optical system 1-100F. The elements of the optical system 1-100F may be substantially similar to the optical system 1-100 described above, and only some of the elements are shown in FIG. 5F. In fig. 5F, the distance 1-L3 between the center 1-312C of the third coil element 1-312 and the center 1-314C of the fifth coil element 1-314 in the Y direction is different from the distance 1-L4 between the center 1-322C of the fourth coil element 1-322 and the center 1-324C of the sixth coil element 1-324, e.g., the distance 1-L3 may be smaller than the distance 1-L4. The first coil elements 1-310, the second coil elements 1-320, the seventh coil elements 1-316, and the eighth coil elements 1-326 may have similar positional relationships, and are not described herein again.

In some embodiments, additional magnetism isolating components may be provided in the optical system, such as on the first movable portion 1-400. For example, FIG. 7A is a schematic diagram of some elements of optical system 1-100G. The elements of the optical system 1-100G may be substantially similar to the optical system 1-100 described above, and only some of the elements are shown in FIG. 7A. The first movable portion 1 to 400 of the optical system 1 to 100G may have a first magnetism isolating member 1 to 332. The first coil component 1-W1 may be disposed on the first side 1-400A of the first movable part 1-400, and the second coil component 1-W2 may be disposed on the third side 1-200A of the first base plate 1-200 with the first side 1-400A facing in the same direction as the third side 1-200A. The first magnetic isolating element 1-332 is at least partially arranged between the first optical component 1-105 (e.g. the first optical element 1-500) and the first coil component 1-W1 or the second coil component 1-W2, and the first magnetic isolating element 1-332 and the first optical component 1-105 (e.g. the first optical element 1-500) at least partially overlap in the direction of the main axis 1-O (Z-direction). Furthermore, the first magnetic shield element 1-332, the first optical element 1-500, and the first coil component 1-W1 are at least partially overlapped in the X direction or the Y direction.

In addition, the first magnetic isolating elements 1-332 may be made of a magnetic material (e.g., metal). By the overlapping position relationship, the interference of the electromagnetic signal generated between the first coil assembly 1-W1 and the second coil assembly 1-W2 on the first optical element 1-500 can be avoided, so that the first optical element 1-500 can obtain a more accurate signal. In addition, the first magnetic isolating elements 1-332 can be partially embedded in the first movable parts 1-400 and partially exposed out of the first movable parts 1-400, so that the required volume is reduced and the miniaturization is realized.

Fig. 7B is a schematic diagram of some elements of the optical system 1-100H. The elements of the optical system 1-100H may be substantially similar to the optical system 1-100 described above, and only some of the elements are shown in FIG. 7B. The first movable section 1-400 of the optical system 1-100H may have a second magnetism isolating element 1-334, for example, on a different side of the first movable section 1-400 from the first coil element 1-310 and the third coil element 1-312. The first coil component 1-W1 may be disposed on the first side 1-400A of the first movable part 1-400, and the second coil component 1-W2 may be disposed on the third side 1-200A of the first base plate 1-200 with the first side 1-400A facing in the same direction as the third side 1-200A.

The second magnetic isolating elements 1-334 may be of similar material as the first magnetic isolating elements 1-332 described previously. The second magnetically isolating element 1-334 is at least partly arranged between the first optical component 1-105 (e.g. the first optical element 1-500) and the first coil component 1-W1 or the second coil component 1-W2, and the second magnetically isolating element 1-334 at least partly overlaps the first optical component 1-105 (e.g. the first optical element 1-500) in the direction of the main axis 1-O (Z-direction). The second flux barrier member 1-334 is at least partially disposed between the first coil block 1-W1 and the second coil block 1-W2 in the direction of the primary axis 1-O. By the overlapping position relationship, the interference of the electromagnetic signal generated between the first coil assembly 1-W1 and the second coil assembly 1-W2 on the first optical element 1-500 can be avoided, so that the first optical element 1-500 can obtain a more accurate signal.

FIG. 7C is a schematic diagram of some of the elements of optical system 1-100I. The elements of the optical system 1-100I may be substantially similar to the optical system 1-100 described above, and only some of the elements are shown in FIG. 7C. The optical system 1-100I may have a third magnetic shielding element 1-336 on the first movable portion 1-400, for example, partially embedded in the first movable portion 1-400 and partially exposed from the first movable portion 1-400. The third magnetic isolating element 1-336 may be of a similar material as the first magnetic isolating element 1-332 described above. The third magnetic isolating element 1-336 is at least partly arranged between the first optical component 1-105 (e.g. the first optical element 1-500) and the first coil component 1-W1 or the second coil component 1-W2.

Although the first coil assemblies 1-W1 are disposed on the side of the first movable portion 1-400 facing away from the second coil assemblies 1-W2 in the above embodiments, the present invention is not limited thereto. For example, in fig. 7C, the first coil component 1-W1 may be disposed on the second side 1-400B of the first movable portion 1-400, and the second coil component 1-W2 may be disposed on the third side 1-200A of the first substrate 1-200, with the second side 1-400B facing toward the third side 1-200A, i.e., facing in the opposite direction.

Further, the first coil block 1-W1, the second coil block 1-W2, and the first optical element 1-500 are disposed on the opposite side of the third magnetism isolating element 1-336. By the overlapping position relationship, the interference of the electromagnetic signal generated between the first coil assembly 1-W1 and the second coil assembly 1-W2 on the first optical element 1-500 can be avoided, so that the first optical element 1-500 can obtain a more accurate signal.

First, second, and third magnetic isolation elements 1-332, 1-334, and 1-336 may be collectively referred to as a magnetic isolation assembly, and although the foregoing embodiments show embodiments in which each optical system has a single magnetic isolation element, it should be understood that first, second, and third magnetic isolation elements 1-332, 1-334, and 1-336 may exist simultaneously, for example, first, second, and third magnetic isolation elements 1-332, 1-334, and 1-336 may be provided in the same optical system simultaneously to achieve a further magnetic isolation effect.

Furthermore, as shown in fig. 7C, an additional energy storage element 1-350 may also be provided on the first movable part 1-400 of the optical system 1-100I, and fig. 7C also shows a first communication element 1-341 and a second communication element 1-342.
