[0037] The following is a detailed description of the embodiments of the present application in conjunction with the accompanying drawings. In the absence of conflict, the features of the following embodiments can be combined with each other.

[0038] This application relates to an electronic device 10, which includes a display panel 200 for performing smart display. In this embodiment, the electronic device 10 is a mobile phone. Of course, in other embodiments, the electronic device 10 can also be other devices with smart display functions, such as computers, tablets, e-books, watches, headphones, etc.

[0039] like Figure 1 As shown, if necessary, combined Figure 2 As shown, the electronic device 10 includes a housing device 100 and a display panel 200 . The display panel 200 is fixed to the housing device 100 and is used to implement intelligent display.

[0040] The housing device 100 includes a middle frame 300, an optical signal generating assembly 400, and a microphone system 500. The middle frame 300 supports the display panel 200. The optical signal generating assembly 400 and the microphone system 500 are both disposed within the middle frame 300, which supports and accommodates them.

[0041] The optical signal generating assembly 400 can realize remote control function by using light. The optical signal generating assembly 400 includes a light guide column 410 and a light emitting unit 420. The light guide column 410 can conduct and diffuse the light emitted by the light emitting unit 420.

[0042] Among them. The light-emitting unit 420 includes an optical signal generator 421 and a control circuit board 422. The light guide column 410, the optical signal generator 421 and the control circuit board 422 are all located inside the middle frame 300. Among them, the optical signal generator 421 is fixed to the control circuit board 422 by welding to achieve a fixed connection and electrical connection between the optical signal generator 421 and the control circuit board 422. At the same time, the optical signal generator 421 in the light-emitting unit 420 faces the light guide column 410 and is used to emit light. The light emitted by the optical signal generator 421 enters the light guide column 410, and the light guide column 410 can conduct the light emitted by the optical signal generator 421 and diffuse it to the outside of the electronic device 10, thereby realizing functions such as the electronic device 10 controlling other devices.

[0043] In this embodiment, optical signal generating assembly 400 is an infrared signal generating assembly, and optical signal generator 421 is an infrared sensor. Of course, in other embodiments, optical signal generating assembly 400 may also be an ultraviolet signal generating assembly. Optical signal generator 421 is a ultraviolet sensor, and the ultraviolet control system also includes light guide column 410. In this case, light guide column 410 also serves to transmit light.

[0044] like Figure 1 As shown, the microphone system 500 includes a main microphone assembly 510 disposed at the bottom of the electronic device 10, and a secondary microphone assembly 520 disposed at the top of the electronic device 10. During use, the secondary microphone assembly 520 can provide noise reduction. The main microphone assembly 510 at the bottom of the electronic device 10 is responsible for transmitting sound information. Sound signals include valid sound signals emitted by the user and external noise signals. For example, when a user is making a call, not only is the user's sound captured by the main microphone assembly 510 and transmitted to the interior of the electronic device 10, but external noise is also captured by the main microphone assembly 510 and transmitted to the interior of the electronic device 10, resulting in poor call quality. By placing the secondary microphone assembly 520 at the top of the middle frame 300, the secondary microphone assembly 520 can simultaneously collect external environmental noise. Subsequently, the sound processor in the electronic device 10 reversely cancels the identical sound waves in the sound signals received by the main microphone assembly 510 and the secondary microphone assembly 520, thereby improving call quality.

[0045] Of course, in other embodiments, the auxiliary microphone component 520 can also be set on the side of the electronic device 10, or set at the bottom of the electronic device 10 together with the main microphone component 510, and set at a certain distance from the main microphone component 510, so as to avoid or reduce the auxiliary microphone component 520 collecting the sound emitted by the user as much as possible, which is conducive to further improving the call quality.

[0046] like Figure 2 and Figure 4 As shown, in this embodiment, a through-hole 310 is provided on the middle frame 300. At least a portion of the light guide 410 is disposed within the hole 310, thereby conducting and dispersing light emitted by the optical signal generator 421. A through-hole sound channel 411 is also provided in the light guide 410. One end of the sound channel 411 connects to the exterior of the middle frame 300, dispersing the light outward. In other words, in this embodiment, one end of the sound channel 411 transmits infrared light emitted by the light-emitting unit 420 outward. The other end of the sound channel 411 connects to the auxiliary microphone assembly 520. In other words, the auxiliary microphone assembly 520 faces the end of the sound channel 411 that is away from the hole 310. In this configuration, the sound channel 411 provided on the light guide 410 allows external sound to pass through the sound channel 411 and enter the auxiliary microphone assembly 520, where it is captured and collected, thereby improving call quality. The transmission path of external sound is as follows Figure 2 In other words, the light guide column 410 can not only conduct and scatter infrared light, but also provide the function of the sound guide channel 411.

[0047] This arrangement avoids the need for additional through-holes in the middle frame 300 (instead, a single through-hole is provided in the middle frame 300 to serve as at least a portion of the sound guide channel 411), thereby improving the aesthetics. Furthermore, the reduced number of through-holes on the outer surface of the middle frame 300 improves the waterproof and dustproof capabilities of the electronic device 10.

[0048] Furthermore, the sound guide channel 411 includes an outlet 4111 and an inlet 4112. The outlet 4111 is farther from the outside world than the inlet 4112 and closer to the auxiliary microphone assembly 520. The outlet 4111 is opened on the peripheral side of the light guide column 410, and the auxiliary microphone assembly 520 faces the outlet 4111. In the above arrangement, avoiding opening the outlet 4111 at the end of the light guide column 410 can prevent external liquid from directly passing through the sound guide channel 411 due to gravity and dripping into the auxiliary microphone assembly 520. At the same time, through this arrangement, it is beneficial to the arrangement of the internal parts of the middle frame 300 and to improve space utilization.

[0049] Combine Figures 1-4As shown, in this embodiment, the axial direction of the light guide column 410 is parallel to the longitudinal direction of the electronic device 10. The light-emitting unit 420 and the auxiliary microphone assembly 520 are respectively located on either side of the light guide column 410 along the axial direction. This can prevent the light guide column 410, the optical signal generating assembly 400, and the auxiliary microphone assembly 520 from excessively occupying the space used for mounting the display panel 200, thereby facilitating an improvement in the screen-to-body ratio of the electronic device 10.

[0050] Further, such as Figure 5 As shown, if necessary, combined Figure 2 As shown. The diameter D3 of the sound guiding channel 411 is greater than or equal to 1 mm. Through a large number of tests, it was found that when the diameter D3 of the sound guiding channel 411 is greater than 1 mm, external sounds can pass through the sound guiding channel 411 smoothly and be captured by the auxiliary microphone assembly 520. The above arrangement is conducive to improving call quality. In this embodiment, the sound guiding channel 411 is a cylindrical structure. Of course, in other implementations, the cross-sectional area of ​​the sound guiding channel 411 may gradually decrease in the direction pointing to the inside of the middle frame 300, forming a truncated cone-shaped structure. At this time, the truncated cone-shaped sound guiding channel 411 can avoid or reduce external impurities from directly passing through the sound guiding channel 411 and entering the auxiliary microphone assembly 520.

[0051] like Figure 5 and Figure 6 As shown, if necessary, combined Figure 2 As shown, the sound guide channel 411 is eccentrically arranged inside the light guide column 410, and the light guide column 410 is divided into a light guide portion 4113 and a support portion 4114. The thickness d11 of the light guide portion is greater than the thickness d2 of the support portion. The optical signal generator 421 faces the light guide portion 4113. In the above arrangement, the light emitted by the optical signal generator 421 can be conducted through the thicker light guide portion 4113. In this embodiment, the maximum thickness of the light guide portion 4113 is greater than or equal to 1 mm. A large number of experiments have shown that when the maximum thickness of the light guide portion 4113 is greater than or equal to 1 mm, the angle at which the light is emitted outward is sufficiently large.

[0052] Through the above arrangement, the internal space of the light guide column 410 is reasonably utilized, and the thickness of the light guide portion 4113 is increased while ensuring the overall angle of the light guide column 410, thereby increasing the angle of infrared light emitted outward by the optical signal generating component 400.

[0053] It should be noted that the light guide column 410 mentioned here is supported by light guide material. Both the light guide part 4113 and the support part 4114 can be used to conduct and emit light. The light guide part 4113 plays the main conduction role, and the support part 4114 plays a certain auxiliary role. It does not mean that the support part 4114 cannot be used to conduct and emit light.

[0054] Furthermore, the light guide column 410 includes a light guide unit 4115 and an extension unit 4116 connected in sequence. The light guide unit 4115 is located in the receiving hole 310, and the extension unit 4116 is located inside the middle frame 300. The light guide portion 4113 and the support portion 4114 are at least part of the structure of the light guide unit 4115. The outer wall surface of the extension unit 4116 near the end of the light guide unit 4115 extends outward to form a positioning unit 4117, which abuts the inner wall surface of the middle frame 300 to provide a positioning function.

[0055] In this embodiment, the cross-sections of the light guide unit 4115 and the sound guide channel 411 are both annular, in other words, both are cylindrical structures. Of course, in other embodiments, the light guide unit 4115 and the sound guide channel 411 can also have other shapes.

[0056] Among them, Figure 2 As shown, the light guide unit 4115 is located in the receiving hole 310, and the ratio of the length L1 of the light guide unit 4115 to the depth L2 of the receiving hole 310 is less than or equal to 1 / 2. This arrangement allows the light guide unit 4115 to be concealed within the receiving hole 310. When a user views the top of the electronic device 10, it is difficult to see the light guide column 410 hidden in the receiving hole 310, and even less so the sound guide channel 411 provided on the light guide column 410, thereby further improving the overall aesthetics of the electronic device 10.

[0057] It should be noted that in this embodiment, the structure of the light guide column 410 located in the receiving hole 310 is used as the light guide unit 4115. The middle frame 300 encloses a receiving space for accommodating components of the electronic device 10. The aforementioned extension unit 4116 located inside the middle frame 300 refers to the extension unit 4116 being located in the receiving space.

[0058] like Figure 2 and Figure 3As shown, the positioning unit 4117 is fixed to the inner wall surface of the middle frame 300 by bonding. Specifically, a sealing adhesive 700 is attached between the positioning unit 4117 and the inner wall surface of the middle frame 300. The sealing foam 600 can not only achieve the bonding and fixation of the positioning unit 4117 and the middle frame 300, but also, because the sealing foam 600 is made of an opaque material, it can also reduce or avoid the light transmitted in the light guide column 410 from leaking out of the gap between the positioning unit 4117 and the middle frame 300, thereby achieving sealing of the optical signal. Of course, in other embodiments, the fixed connection between the positioning unit 4117 and the middle frame 300 can also be achieved by other means. An optical pattern 4118 is provided at the end of the positioning unit 4117 away from the light guide unit 4115, and the emission port of the optical signal generator 421 is oriented toward the center of the optical pattern 4118. By providing optical lines 4118 thereon, the direction of light transmission and / or divergence of the light guide 410 can be controlled. The optical signal generator 421 can also be abutted against the outer wall of the extension unit 4116 to further stabilize the structure of the optical signal generator 421.

[0059] Furthermore, the auxiliary microphone assembly 520 is fixed to the periphery of the extension unit 4116, with a sealing foam 600 attached between the two. A sound hole 610 is provided through the sealing foam 600, facing the exit 4111 of the sound guide channel 411. External sound enters the auxiliary microphone assembly 520 through the portion of the receiving hole 310, the sound guide channel 411, and the sound hole 610. This arrangement effectively seals the optical signal and prevents leakage and distortion of the sound signal.

[0060] The above description is merely a preferred embodiment of the present application and does not constitute any form of limitation to the present application. Although the present application has been disclosed as above with preferred embodiments, it is not intended to limit the present application. Any technician familiar with this profession can make slight changes or modifications to equivalent embodiments with equivalent changes using the technical contents disclosed above without departing from the scope of the technical solution of the present application. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present application without departing from the content of the technical solution of the present application are still within the scope of the technical solution of the present application.
