The accommodating space 101 may be used to mount electronic devices required by the electronic device 100, such as a sensor, a microphone, a speaker, a flash, a circuit board, and a battery, so as to implement functions such as voice communication, audio playing, and lighting. It can be understood that: all directional indications (such as up, down, left, right, front, and rear … …) in the embodiments of the present application are only used to explain the relative positional relationship between the components, the movement, and the like in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indication is changed accordingly.

In an embodiment, the casing 20 generally includes a middle frame 21 and a cover plate 22, the display screen 10 is connected to one side of the middle frame 21, and the cover plate 22 is connected to the other opposite side of the middle frame 21, that is, the display screen 10 and the cover plate 22 can be respectively covered on the two opposite sides of the middle frame 21 and enclose the accommodating space 101.

Wherein, the housing 20 may be provided with a hole 102 formed through a surface of the housing 20, and external information (for example, external light information or external sound information) of the electronic device 100 may be guided to the conductive member 30 through the hole 102. I.e., the aperture 102, is configured for directing external information to the conductive member 30 and to the sensing device 40 via the conductive member 30. The sensing device 40 may convert the received information into electrical signals for transmission within the electronic device 100.

It is understood that the sensing device 40 may be a sensor device that converts external analog information of the electronic apparatus 100 into an electronic signal. For example, the sensing Device 40 may convert an optical Image into an electronic signal, and the sensing Device 40 may be a Device equipped with one or more sensors among a CCD (Charge-coupled Device), a CMOS (Complementary Metal Oxide Semiconductor), and a CIS (CMOS Image Sensor).

It will be appreciated that the longer and shorter sides described above are merely relative, and that in some scenarios a switch may be made. The XY-plane is generally parallel to the display surface of the display screen 10, or the XY-plane generally defines the display surface of the display screen 10. The Z direction is substantially orthogonal to the XY plane.

Referring to fig. 3, fig. 3 is a partial schematic structural diagram of the electronic device 100 according to some embodiments of the present disclosure, in which the conducting assembly 30 and the sensing device 40 are accommodated in an accommodating space of the electronic device 100 and configured to collect external light information or external sound information of the electronic device 100.

Wherein, when the sensing device 40 is an optical sensing device (e.g. an image sensor, etc.), i.e. the sensing device 40 is configured for receiving light signals, the conductive member 30 is configured for guiding light signals entering the electronic device 100 via the aperture 102 to the sensing device 40. When the sensing apparatus 40 is an acoustic sensing device (e.g., a microphone, etc.), i.e., the sensing apparatus 40 is configured for receiving a sound signal, the conductive component 30 is configured for directing the sound signal entering the electronic device 100 via the aperture 102 to the sensing apparatus 40.

Further, the conductive member 30 is formed with an information passage for guiding information propagation, one end of which communicates with the hole 102 and the other end communicates with the sensing means 40. I.e. the information channel is configured for guiding information entering the electronic device 100 via the aperture 102 to the sensing means 40. External information is directed from the aperture 102 to the conductive member 30 and changes the direction of propagation of the information via the conductive member 30 to reach the sensing device 40.

It will be appreciated that when the conductive member 30 is configured for conducting light information, the aperture 102 may direct light with a light signal to the conductive member 30, and the conductive member 30 may be formed with an optical channel to direct light to the sensing device 40. When the conductive member 30 is configured for conducting acoustic information, the aperture 102 may direct acoustic waves carrying the acoustic information to the conductive member 30, and the conductive member 30 may form an acoustic channel to direct the acoustic waves to the sensing device 40.

The following description is given by taking the example that the conductive component 30 is configured to conduct light information, that is, the conductive component 30 generally includes a lens assembly 31 and a conductive element 32. The lens group 31 is disposed corresponding to the hole 102 and configured to collect external light of the electronic apparatus 100 under the guidance of the hole 102. The lens assembly 31 and the conductive element 32 cooperate to form an optical channel for guiding light to propagate, and one end of the optical channel is connected to the hole 102, and the other end is connected to the sensing device 40. I.e. the optical channel is configured for guiding light entering the housing 20 via the aperture 102 to the sensing device 40. The external light enters the lens assembly 31 from the hole 102, and is converted into parallel light through the lens assembly 31 to enter the conducting element 32. The light incident to the conductive member 32 is transmitted and folded by the conductive member 32 and then is incident to the sensing device 40 in parallel. That is, the light incident from the lens assembly 31 to the first reflecting surface 321 is parallel to and opposite to the light reflected from the second reflecting surface 321 to the sensing device 40.

It will be appreciated that when the conductive assembly 30 is configured for light propagation, the conductive element 32 may be a triangular prism, a quadrilateral prism, or the like. When the conducting assembly 30 is configured for sound propagation, the conducting assembly 30 may be a structural member provided with a sound propagation channel, that is, the conducting assembly 30 may be formed with a sound cavity for sound wave conduction and a sound inlet and a sound outlet communicating with the sound cavity, the sound inlet is communicated to the hole 102, and the sound outlet is communicated to the sensing device 40. It should be noted that although the embodiment of the present application mainly uses the conduction component 30 for light propagation as an example for illustration, the technical solutions about the conduction component 30 for sound propagation, which are directly derived by the technical solutions in the embodiments of the present application, should be understood as being within the protection scope of the present application.

In other words, when the conducting assembly 30 is configured for light propagation, the conducting assembly 30 comprises the lens set 31 and the conducting element 32, the lens set 31 being disposed opposite the hole 102, for example, facing the hole 102, the conducting element 32 being disposed on a side of the lens set 31 facing away from the hole 102. When the conducting member 30 is configured for sound propagation, the conducting member 30 may include a conducting member 32, the conducting member 32 is formed with a sound cavity for sound wave conduction and a sound inlet and a sound outlet communicating with the sound cavity, the sound inlet is communicated to the hole 102, the sound outlet is communicated to the sensing device 40, the sensing device 40 is disposed at one side of the hole 102 in an axial direction orthogonal to the hole 102, and the hole 102 and the sensing device 40 are disposed at the same side of the conducting member 32.

Specifically, the lens group 31 has an optical axis L. Optionally, the optical axis L is substantially parallel to the axis of the hole 102. Preferably, the optical axis L is collinear with the axis of the bore 102. The sensing device 40 is disposed on one side of the lens group 31 in a direction orthogonal to the optical axis L, and the conductive member 32 and the lens group 31 are disposed at an interval in the extending direction of the optical axis. I.e. in a direction orthogonal to the optical axis L, the lens group 31 and the sensing means 40 are arranged side by side. Further, the lens assembly 31 generally includes a light-entering surface 31a and a light-exiting surface 31b disposed opposite to each other, and the sensing device 40 has a sensing surface 40a corresponding to the light-exiting surface 31 b. External light enters the lens assembly 31 from the light entrance surface 31a and exits through the light exit surface 31b to reach the conducting element 32, and the light is conducted and folded by the conducting element 32 to reach the sensing surface 40a of the sensing device 40. The light incident from the light emitting surface 31b to the conducting element 32 is substantially parallel to the light incident from the conducting element 32 to the sensing surface 40 a. Optionally, the light entering surface 31a and the light exiting surface 31b of the lens assembly 31 are spaced apart in the Z direction, that is, the light exiting surface 31b is located between the light entering surface 31a and the conducting element 32. The sensing surface 40a of the sensing device is disposed corresponding to the light emitting surface 31b, i.e., adjacent to the conducting element 32.

The conducting element 32 has a first reflecting surface 321 and a second reflecting surface 322, the first reflecting surface 321 is disposed opposite to the lens group 31, and the second reflecting surface 322 is disposed opposite to the sensing device 40. Optionally, the first reflection surface 321 is disposed opposite to the light exit surface 31b of the lens group 31, so that the light from the lens group 31 can be incident on the first reflection surface 321. The second reflecting surface 322 is disposed opposite to the sensing surface 40a of the sensing device 40 so that the light reflected by the second reflecting surface 322 can reach the sensing surface 40a of the sensing device 40.

Further, the lens group 31 and the sensing device 40 are disposed on the same side of the conducting element 32, light from the lens group 31 is incident on the first reflecting surface 321, light reflected at the first reflecting surface 321 is at least partially conducted to the second reflecting surface 322 via the conducting element 32, and light reflected at the second reflecting surface 322 at least partially passes through the conducting element 32 to reach the sensing device 40.

Specifically, in the Z direction, the lens group 31 and the sensing device 40 are located above the conducting member 32, that is, the lens group 31 is located directly above the first reflecting surface 321, and the sensing device 40 is located directly above the second reflecting surface 322. The light emitted from the light emitting surface 31b of the lens assembly 31 can reach the first reflecting surface 321 and be reflected by the first reflecting surface 321 to be folded and transmitted on the transmitting element 32, and further, the light reflected by the first reflecting surface 321 is at least partially transmitted to the second reflecting surface 322 and is reflected by the second reflecting surface 322 to be transmitted to the sensing surface 40a of the sensing device 40.

The lens group 31 may include at least one lens (e.g., a convex lens), and as shown in fig. 3, the lens group 31 generally includes a first lens 311, a second lens 312, a third lens 313 and a fourth lens 314, which are sequentially disposed at intervals, the first lens 311 is disposed near the hole 102, and the fourth lens 314 is disposed far from the hole 102 relative to the first lens 311. That is, the light entering the housing 20 from the hole 102 sequentially passes through the first lens 311, the second lens 312, the third lens 313 and the fourth lens 314 and then enters the conductor 32. Alternatively, the optical axes of the first lens 311, the second lens 312, the third lens 313, and the fourth lens 314 are collinear, i.e., substantially equivalent to the optical axis L of the lens group 31. It should be understood that the number, shape and distribution of the lenses in the lens group 31 can be set by those skilled in the art according to the actual requirement.

The first lens 311 may be made of glass and shaped by grinding, and is mainly used for correcting aberration and eliminating temperature drift. The second lens 312, the third lens 313 and the fourth lens 314 can be made of plastic and are formed by injection molding, which is mainly used for correcting aberration. It should be understood that the present embodiment only exemplifies the materials and processing methods of the lens, but is not limited thereto, and those skilled in the art can flexibly select the materials and processing methods according to actual needs.

It can be understood that, according to the electronic device provided by the embodiment of the present application, the lens group and the sensing device are disposed on the same side of the conducting element, so that the overall space occupied by the conducting element and the sensing device in the thickness direction of the electronic device can be reduced, and the focusing stroke of the electronic device can be reduced.

Specifically, based on the technical scheme that the lens group and the sensing device are arranged on the same side of the conducting piece, and different from the technical scheme that the lens group and the sensing device are arranged on the two opposite sides of the conducting piece, in the process of carrying out optical focusing, optical focusing can be realized by moving the conducting piece, and the focusing scheme can roughly reduce the focusing stroke by one time compared with the focusing scheme of moving the lens group or the sensing device.

It can be understood that when the conduction assembly is used for conducting sound wave information, the sound cavity for conducting sound waves and the sound inlet and the sound outlet which are communicated with the sound cavity are formed in the conduction piece, the sound inlet is communicated to the hole, the sound outlet is communicated to the sensing device, the sensing device is arranged on one side of the hole in the axial direction orthogonal to the hole, and the hole and the sensing device are arranged on the same side of the conduction piece. The first reflective surface is disposed opposite the aperture and the second reflective surface is disposed opposite the sensing device. Information external to the electronic device (e.g., acoustic information) may be directed via the aperture to the first reflective surface, the information reflected at the first reflective surface being at least partially conducted via the conductive member to the second reflective surface, the information reflected at the second reflective surface being at least partially transmitted through the conductive member to reach the sensing device.

Of course, in other embodiments, when the conducting assembly is used for conducting light information, the conducting assembly may also only include the conducting element, i.e. the lens assembly may be eliminated, and the conducting element is formed with an optical channel for light to propagate. Specifically, the hole and the sensing device are arranged on the same side of the conducting piece, the light inlet end of the conducting piece is arranged opposite to the hole, and the light outlet end of the conducting piece is arranged opposite to the sensing device. Optical information external to the electronic device is directed via the aperture to the first reflective surface, the optical information reflected at the first reflective surface is at least partially conducted via the conductive member to the second reflective surface, and the optical information reflected at the second reflective surface is at least partially transmitted through the conductive member to reach the sensing device.

In one embodiment, the conducting element 32 further has a third reflecting surface 323 disposed between the first reflecting surface 321 and the second reflecting surface 322. The light reflected at the first reflecting surface 321 is at least partially incident on the third reflecting surface 323, the light reflected at the third reflecting surface 323 is at least partially incident on the second reflecting surface 322, and the light reflected at the second reflecting surface 322 is at least partially transmitted through the third reflecting surface 323 to the sensing device 40. Specifically, the third reflecting surface 323 is provided on the first reflecting surface 321 and the second reflecting surface 322 of the transmitter 32 on the side close to the lens group 31, and is located directly below the lens group 31 and the sensor device 40 in the Z direction. Optionally, the third reflecting surface 323 is substantially parallel to the XY plane and spaced apart from the light emitting surface 31b and the sensing surface 40 a.

In an embodiment, a projection of the first reflecting surface 321 onto a plane of the third reflecting surface 323 has a first width W1 in the first direction, and a projection of the lens set 31 onto a plane of the third reflecting surface 323 has a second width W2 in the first direction. The first width W1 is not less than the second width W2. The projection of the second reflecting surface 322 on the plane of the third reflecting surface 323 has a third width W3 in the first direction, and the projection of the sensing surface 40a of the sensing device 40 on the plane of the third reflecting surface 323 has a fourth width W4 in the first direction. Wherein the third width W3 is not less than the fourth width W4. The first direction may be a direction orthogonal to the optical axis L, in other words, the first direction may be an arrangement direction of the lens group 31 and the sensing device 40, that is, the first direction may be an arrangement direction of the lens group 31 and the sensing device 40 on an XY plane.

To further illustrate the advantages of the above embodiments of the present application in reducing the overall space occupied by the conductive assembly and the sensing device and the focusing stroke, the present application further introduces a comparative example to further illustrate this. Referring to fig. 4, fig. 4 is a partial schematic structural diagram of an electronic device 200 according to another embodiment of the present disclosure, in which the electronic device 200 generally includes a conducting assembly 60 and a sensing device 40, the conducting assembly 60 generally includes a lens assembly 61 and a conducting element 62, and the lens assembly 61 and the sensing device 40 are disposed on opposite sides of the conducting element 62. Reference is made, among others, to the lens group 31 and the sensing device 40 in the foregoing embodiments with regard to the related technical features of the lens group 61 and the sensing device 40. Wherein the conductive element 32 may be a triangular prism and the conductive element 62 may be a parallelogram prism.

The conductive member 62 generally includes a first reflective surface 621 and a second reflective surface 622 oppositely disposed, and a third reflective surface 623 and a fourth reflective surface 624 disposed between the first reflective surface 621 and the second reflective surface 622. The first reflecting surface 621 and the second reflecting surface 622 are opposite and parallel to each other, and the third reflecting surface 623 and the fourth reflecting surface 624 are opposite and parallel to each other. The first reflecting surface 621 is disposed opposite to the light emitting surface of the lens assembly 61, and the second reflecting surface 622 is disposed opposite to the sensing surface of the sensing device 40. Light from the lens group 61 is incident on the first reflecting surface 621, and light reflected at the first reflecting surface 621 is at least partially incident on the third reflecting surface 623, light reflected at the third reflecting surface 623 is at least partially incident on the fourth reflecting surface 624, light reflected at the fourth reflecting surface 624 is at least partially incident on the second reflecting surface 622, and light reflected at the second reflecting surface 622 is at least partially transmitted through the fourth reflecting surface 624 to the sensing device 40.

As compared with the electronic apparatus 100 and the electronic apparatus 200, the light incident on the conductive element 32 from the lens group 31 is reflected three times in the conductive element 32, and is then emitted out of the conductive element 32 to reach the sensing device 40; the light incident on the transmission element 62 from the lens assembly 61 exits the transmission element 62 after being reflected four times in the transmission element 62 to reach the sensing device 40. The back focal length of the lens group of the conducting assembly can be defined as the path length of the light emitted from the lens group and reaching the sensing device.

Referring to fig. 5 and 6 in combination, fig. 5 is a schematic view of a conductive path of a conductive element 30 in some embodiments of the present application, and fig. 6 is a schematic view of a conductive path of a conductive element 60 in other embodiments of the present application. Here, it is defined that the widths of the lens group 31 and the lens group 61 in the same direction on the XY plane are uniform, that is, the second width W2(W2 may be not more than 10 mm). The relationship defining the first width W1, the second width W2, and the third width W3 is: w1 ═ W2 ═ W3. The light reflection angles theta of the

conductors

32 and 62 are defined to be 30 deg. in unison. The distance J0 is defined as the distance between the light-emitting surface of the lens assembly 31 and the conducting element 32, the distance between the light-emitting surface of the lens assembly 61 and the conducting element 62, the distance between the conducting element 32 and the sensing surface of the sensing device 40, and the distance between the conducting element 62 and the sensing surface of the sensing device 40 being the same. It follows from the above parameters that the path length J1 of the light in the conducting component 30 in the electronic device 100 after exiting from the lens group 31 to the sensing device 40 is 2J0+3W2/√ 3. The path length J2 of the light in the conducting component 60 in the electronic device 200 after exiting from the lens group 61 to the sensing device 40 is 2J0+5W2/√ 3. That is, for the conductive element 32 and the conductive element 62, the path of light propagating in the conductive element 62 is longer, thereby making the back focal length of the lens group 62 relatively longer.

Through a plurality of experiments, the conduction assembly 30 is approximately suitable for the lens group 31 with 2-4 times (the equivalent focal length is approximately 40-90 mm); the conductive assembly 60 is generally suitable for use with a lens assembly 61 of power 3-10 times (equivalent focal length is generally 65-200 mm).

Further comparing the electronic device 100 and the electronic device 200, it can be seen that: in the electronic apparatus 100, the space (thickness in the Z direction as an example) occupied by the conductive member 30 and the sensing device 40 is substantially the sum of the lens group 31, the conductive member 32, and J0. In the electronic apparatus 200, the space (thickness in the Z direction, for example) occupied by the conductive member 30 and the sensing device 40 is substantially the sum of the lens group 31, the conductive element 32, the sensing device 40, and 2J 0. Obviously, the solution in the electronic device 100 has significant advantages in terms of space utilization.

Still further, the electronic device 100 may be realized not only by moving the lens group 61 and/or the sensing device 40, but also by moving the conducting element 32 during focusing. While the electronic device 200 can only be realized by moving the lens group 61 and/or the sensing means 40 during focusing. Obviously, the electronic device 100 has more flexibility in selecting the focusing scheme, and in the technical scheme of implementing focusing by moving the conducting element 32, the focusing distance is equal to half of the distance of moving the lens group or the sensing device, i.e. the focusing stroke can be reduced.

Referring again to fig. 5 and 6, in the electronic apparatus 100, the lens group 31 has a first height h1 along the optical axis direction thereof, and the first height h1 is generally not more than 8mm, and may be not more than 6mm, for example. A second height h2 is provided between a surface/line of the conducting element 32 facing away from the lens assembly 31 and the light-emitting surface of the lens assembly 31, and the second height h2 is generally not more than 5mm, for example, may not be more than 4 mm. It follows that in the electronic apparatus 100, the height h of the conducting member 30 and the sensing device 40 in the direction along the optical axis of the lens group 31 (h 1+ h 2) (occupying the height space of the electronic apparatus 100) does not generally exceed 13mm, and may not exceed 10mm, for example.

In the electronic apparatus 200, the lens group 61 has a first height H1 in the optical axis direction thereof, and the first height H1 is generally not more than 8mm, and may be not more than 6mm, for example. The surface/line of the conducting element 62 facing away from the lens assembly 61 and the light-emitting surface of the lens assembly 61 have a second height H2, and the second height H2 is generally not more than 5mm, for example, may not be more than 4 mm. The face/line of the conducting element 62 facing away from the lens group 61 and the sensing device 40 has a third height H3, and the third height H3 is generally not more than 2mm, for example, may not be more than 1 mm. It follows that in the electronic apparatus 200, the height H ═ H1+ H2+ H3 (occupying the height space of the electronic apparatus 100) of the conductive member 60 and the sensing device 40 in the direction of the optical axis of the lens group 61 is generally not more than 15mm, and may be not more than 11mm, for example.

That is, compared with the electronic apparatus 100 and the electronic apparatus 200, the conductive component and the sensing device in the electronic apparatus 200 occupy a larger height space of the electronic apparatus in the optical axis direction of the lens group under the condition that the thickness of each component is the same.

To further illustrate the structure and performance differences of the electronic device 100 and the electronic device 200, please refer to table 1, which is a performance comparison table of the electronic device 100 and the electronic device 200.

Table 1: performance comparison table for electronic device 100 and electronic device 200

In combination with the above table, the electronic device 100 has certain advantages in terms of overall space usage and optical performance compared to the electronic device 200.

Of course, in other embodiments, the information (e.g. light or sound information) from the lens set 31 is incident on the first reflecting surface 321, and at least part of the information reflected at the first reflecting surface 321 is directly incident on the second reflecting surface 322, i.e. the information reflected at the first reflecting surface 321 may be directly conducted to the second reflecting surface 322 without passing through the third reflecting surface 323, and the light reflected at the second reflecting surface 322 can reach the sensing device 40. For example, taking the reflection angle θ of the conductive element 32 as 45 °, the information from the lens 31 is directly reflected to the second reflection surface 322 at the first reflection surface 321, and is reflected to the sensing device 40 at the second reflection surface 322.

Referring to fig. 7 and 8, fig. 7 is a partial structural schematic diagram of an electronic device 100 according to some embodiments of the present application, fig. 8 is a partial structural schematic diagram of an electronic device 300 according to other embodiments of the present application, where the electronic device 300 generally includes a conducting element 70 and a sensing device 40, the conducting element 70 generally includes a lens assembly 71 and a conducting element 72, and the lens assembly 71 and the sensing device 40 are disposed on two opposite sides of the conducting element 72. Reference is made, among others, to the lens group 31 and the sensing device 40 in the foregoing embodiments with regard to relevant technical features of the lens group 71 and the sensing device 40.

As shown in fig. 7, the conductive member 32 may be a triangular prism, that is, the conductive member 32 generally includes a first wall 32a, a second wall 32b, and a third wall 32c connected end to end in sequence. The first, second, and

third walls

32a, 32b, and 32c enclose the information transmission passage of the stroke transmitter 32. Wherein the first wall 32a is disposed opposite to the aperture 102/lens group 21, the second wall 32b is disposed opposite to the sensing device 40, and the third wall 32c is disposed on a side of the first wall 32a and the second wall 32b close to the sensing device 40. That is, the first wall 32a and the second wall 32b constitute side walls of the triangular prism, and the third wall 32c constitutes a bottom wall of the triangular prism.

Wherein the first wall 32a is obliquely disposed with respect to the third wall 32c, the second wall 32b is obliquely disposed with respect to the third wall 32c, and an included angle between the first wall 32a and the third wall 32c is substantially identical to an included angle between the second wall 32b and the third wall 32 c. For example, the angle generally does not exceed 45 °, and preferably the angle may be 30 °. In one embodiment, the surface of the first wall 32a adjacent to the third wall 32c forms at least a portion of the first reflective surface, the surface of the second wall 32b adjacent to the third wall 32c forms at least a portion of the second reflective surface, and the surface of the third wall 32c adjacent to the first wall 32a and the second wall 32b forms at least a portion of the third reflective surface.

Further, the first reflective surface, the second reflective surface and the third reflective surface may be smooth planes to facilitate reflection of the information. For example, the first reflective surface may be formed on the surface of the first wall 32a by a metal material such as aluminum plating or silver, the second reflective surface may be formed on the surface of the second wall 32b by a metal material such as aluminum plating or silver, and the third reflective surface may be formed on the surface of the third wall 32c by a metal material such as aluminum plating or silver. It can be understood that the reflection surface can have a good specular reflection effect by plating the surface with a metal material such as aluminum or silver.

As shown in fig. 8, the conductive member 72 may be a trapezoidal prism, i.e., the conductive member 72 generally includes first and second oppositely disposed

walls

72a, 72b and third and fourth oppositely disposed

walls

72c, 72 d. The first wall 72a, the second wall 72b, the third wall 72c, and the fourth wall 72d enclose an information transmission passage of the stroke conductor 72. Wherein the first wall 72a is disposed opposite the aperture 102/lens assembly 31, the second wall 72b is disposed opposite the sensing device 40, and the first wall 72a and the second wall 72b are disposed between the third wall 72c and the fourth wall 72d, i.e., the third wall 72c and the fourth wall 72d are disposed between the first wall 72a and the second wall 72 b. The third wall 72c is located between the fourth wall 72d and the sensing device 40. The third wall 72c and the fourth wall 72d are disposed generally parallel, and the first wall 72a and the second wall 72b are disposed obliquely with respect to the third wall 72c and the fourth wall 72 d. The first wall 72a and the second wall 72b constitute the waist of the trapezoidal prism, and the third wall 72c and the fourth wall 72d constitute the lower base and the upper base of the trapezoidal prism, respectively. Wherein the projection of the fourth wall 72d onto the third wall 72c covers a portion of the third wall 72c and does not extend beyond the third wall 72 c.

Wherein the first wall 72a is obliquely disposed relative to the third wall 72c, the second wall 72b is obliquely disposed relative to the third wall 72c, and the included angle between the first wall 72a and the third wall 72c is substantially the same as the included angle between the second wall 72b and the third wall 72 c. For example, the angle is generally not more than 45 °, and preferably, the angle may be 30 °. In one embodiment, the first wall 72a forms at least a portion of the first reflective surface adjacent to the surface of the third wall 72c, the second wall 72b forms at least a portion of the second reflective surface adjacent to the surface of the third wall 72c, and the third wall 72c forms at least a portion of the third reflective surface adjacent to the surfaces of the first wall 72a and the second wall 72 b.

Further, the first reflective surface, the second reflective surface and the third reflective surface may be smooth planes to facilitate reflection of the information. For example, a first reflective surface may be formed on the surface of the first wall 72a by a metal material such as aluminum plating or silver, a second reflective surface may be formed on the surface of the second wall 72b by a metal material such as aluminum plating or silver, and a third reflective surface may be formed on the surface of the third wall 72c by a metal material such as aluminum plating or silver. It can be understood that the reflective surface can have a good specular reflection effect by plating the surface with a metal material such as aluminum or silver.

Comparing the conductive element 32 and the conductive element 72, the height of the conductive element 72 in the optical axis direction of the lens assembly, i.e. the Z direction of the electronic device, is smaller than the corresponding height of the conductive element 32, so that the layout space occupied by the conductive elements and the sensing device can be further optimized.

In one embodiment, the conductive element may be made of a glass material by a cold working process to extend the optical path. Of course, in other embodiments, the conducting element may be made of other materials or by other processes to achieve the effect of extending the optical path. Further, the first reflecting surface and the second reflecting surface may be formed by coating a dielectric film to form mirror reflection, and the third reflecting surface may be formed by coating an antireflection film, so that light rays of the third reflecting surface near the lens group can be transmitted through the third reflecting surface, and light rays of the third reflecting surface far from the lens group can be totally reflected on the third reflecting surface.

In one embodiment, the conductive element is a triangular prism. The conductive element may comprise a single unitary body or a combination of a plurality of prisms. Optionally, the conducting element may connect the two prisms together by optical gluing, and the use of prism gluing may provide an aperture screen to reduce or mitigate stray light.
