Description

Technical Field

[0001] This disclosure relates to the field of electronic technology, specifically to a terminal device. Background Technology

[0002] As people's demands for terminal devices increase, the settings and functions on these devices are becoming increasingly diverse. Currently, many terminal devices, in addition to having a display screen on the front, also have a secondary display screen on the back to provide users with more novel display modes. For example, many foldable devices have a secondary display screen on the battery cover, so that users can operate the foldable device without opening the phone when it is folded.

[0003] However, since the terminal device also has a camera on the battery cover, and there is a metal camera decorative component around the camera, the camera decorative component protrudes from the battery cover. When the terminal device is dropped, the camera decorative component will be impacted and vibrate or shake. Therefore, in order to avoid the camera decorative component from colliding with the edge of the secondary display screen, the secondary display screen and the camera decorative component are placed at two positions on the battery cover at a certain distance.

[0004] While the above structure eliminates the risk of collision, it significantly reduces the screen-to-body ratio of the secondary display, which is not conducive to meeting users' demand for a larger secondary display. Utility Model Content

[0005] This disclosure provides a terminal device that can solve the technical problems existing in related technologies. The technical solution is as follows:

[0006] This disclosure provides a terminal device, which includes a mid-frame, a secondary display screen, a camera decorative assembly, and a support component;

[0007] The secondary display screen is located on one side of the middle frame, and the edge of the secondary display screen is connected to the middle frame. The secondary display screen has a camera receiving hole.

[0008] The camera decorative component passes through the camera receiving hole, with a first end located between the sub-display and the middle frame, and a second end located on the side of the sub-display away from the middle frame. The camera decorative component is connected to the display side and / or backlight side of the sub-display.

[0009] The support member is located between the first end of the camera decorative assembly and the middle frame, and the two ends of the support member are respectively connected to the first end of the camera decorative assembly and the middle frame.

[0010] In the technical solution provided in this disclosure, a secondary display screen replaces the battery cover in related technologies, avoiding the impact of the battery cover on the screen-to-body ratio of the secondary display screen, thereby increasing the screen-to-body ratio of the secondary display screen. Furthermore, the terminal device includes a support component. When the terminal device is dropped, the camera decorative component transmits the impact force to the mid-frame through the support component, thereby reducing the amplitude of vibration of the camera decorative component and improving its stability. Thus, even if the gap between the camera decorative component and the inner wall of the camera housing hole of the secondary display screen is small, it will not collide with it. This ensures that the secondary display screen has a high screen-to-body ratio while improving the stability and safety of the terminal device.

[0011] In some possible implementations, the terminal device further includes a first buffer located between the secondary display screen and the first end of the camera decorative assembly, and connected to the backlight side of the secondary display screen and the first end of the camera decorative assembly, respectively.

[0012] In the technical solution provided in this disclosure, the first buffer connects the secondary display screen and the camera decorative component together. On the one hand, it improves the stability of the secondary display screen. On the other hand, when the terminal device is dropped, the first buffer can further fix the relative position between the secondary display screen and the camera decorative component and alleviate the impact between the two, avoiding relative collision between the two, thereby improving the stability and safety of the terminal device.

[0013] In some possible implementations, the camera decorative assembly has an annular structure that passes through the camera receiving hole;

[0014] The support component includes multiple support blocks, which are distributed around the annular structure of the camera decorative component. The two ends of each support block are connected to the first end of the camera decorative component and the middle frame, respectively.

[0015] In the technical solution provided in this disclosure, multiple support blocks are used to provide multi-faceted support for the camera decorative component, thereby improving the stability of the camera decorative component and thus enhancing the stability and security of the terminal device.

[0016] In some possible implementations, the terminal device further includes a light-emitting component, the light-emitting portion of which is located between the secondary display screen and the second end of the camera decorative component;

[0017] There is a first annular gap between the secondary display screen and the second end of the camera decorative assembly, and the first annular gap is connected to the space where the light-emitting part is located.

[0018] In the technical solution provided in this disclosure, since there will inevitably be a black border area at the edge of the camera receiving hole of the secondary display screen, the light-emitting part of the light-emitting component is set between the second end of the secondary display screen and the camera decorative component. When the light-emitting part of the light-emitting component emits light, the light can visually reduce the black border effect of the secondary display screen, thereby improving the display effect of the terminal device.

[0019] In some possible implementations, the camera decorative assembly has an annular structure that passes through the camera receiving hole, and the second end of the camera decorative assembly has a receiving groove on the side near the sub-display that communicates with the first annular gap.

[0020] The light-emitting component includes a light guide ring, a flexible circuit board, and a light-emitting device;

[0021] The light guide ring is coaxially arranged with the annular structure of the camera decorative component and is located in the first annular gap. The two sides of the light guide ring are respectively connected to the sub-display screen and the camera decorative component.

[0022] The first end of the flexible circuit board is located in the receiving groove and is connected to the inner wall of the receiving groove. The second end of the flexible circuit board is located between the sub-display screen and the middle frame, and is used for electrical connection with the motherboard of the terminal device.

[0023] The light-emitting device is located within the receiving groove and is electrically connected to the flexible circuit board.

[0024] The technical solution provided in this disclosure provides a structure for a light-emitting component. The terminal device can control the light-emitting device to emit light through a flexible circuit board. The light beam emitted by the light-emitting device can be conducted to the light guide ring through the connected receiving groove and the first annular gap, and then conducted to the external environment from the light guide ring, thereby reducing the black border effect of the secondary display screen and improving the display effect of the terminal device.

[0025] In some possible implementations, the outer ring portion of the light guide ring is located in the first annular gap, and the inner ring portion of the light guide ring is located in the receiving groove;

[0026] The light-emitting device is located between the inner ring of the light guide ring and the flexible circuit board.

[0027] In the technical solution provided in this disclosure, the light-emitting device is placed between the inner ring of the light guide ring and the flexible circuit board, which avoids the flexible circuit board from blocking the light beam emitted by the light-emitting device, thereby improving the light guiding effect of the light guide ring and thus improving the display effect of the terminal device.

[0028] In some possible implementations, the terminal device further includes a speaker assembly located between the mid-frame and the sub-display, and connected to the mid-frame.

[0029] In the technical solution provided in this disclosure, a speaker component is set between the middle frame and the secondary display screen, which can improve the synchronization performance between the sound emitted by the speaker component and the image displayed on the secondary display screen, thereby improving the user experience of the terminal device.

[0030] Furthermore, the terminal device can also be equipped with multiple other speaker components, which can be located at the top and / or bottom of the terminal device. Together with other speaker components, these speaker components can achieve a stereo effect, further enhancing the usability of the terminal device.

[0031] In some possible implementations, the side of the middle frame closest to the speaker has a rear acoustic cavity groove;

[0032] The speaker assembly includes a first circuit board, a first annular seal, and a speaker.

[0033] The first circuit board is located on the side of the middle frame closer to the secondary display screen and is connected to the middle frame. The first circuit board has a first sound transmission hole.

[0034] The first annular seal is located between the first circuit board and the middle frame, and the two ends of the central hole of the first annular seal cover the first sound transmission hole and the rear sound cavity groove, respectively.

[0035] The speaker is located on the side of the first circuit board away from the middle frame, the speaker is electrically connected to the first circuit board, and covers the first sound transmission hole.

[0036] The technical solution provided in this disclosure provides a structure for a speaker assembly. The terminal device can control the speaker to emit sound through a first circuit board. The sound wave is transmitted through a first sound transmission hole to the rear sound cavity for sound optimization, making the sound more rounded and full. Then the sound is transmitted outward, thereby improving the audio effect of the speaker assembly. The first annular seal can seal the space between the first circuit board and the middle frame, preventing sound waves from leaking out during the transmission between the speaker and the rear sound cavity, further improving the audio effect of the speaker assembly.

[0037] In some possible implementations, the speaker assembly further includes a shim block and a second annular seal;

[0038] The shim block is located on the side of the first circuit board away from the middle frame and is connected to the first circuit board. The side of the shim block near the first circuit board has a speaker receiving groove, and the bottom of the speaker receiving groove has a second sound transmission hole.

[0039] The loudspeaker is located in the loudspeaker housing slot;

[0040] The outer wall of the second annular seal is connected to the speaker receiving groove, and the inner wall of the second annular seal is connected to the outer wall of the speaker.

[0041] In the technical solution provided in this disclosure, on the one hand, the second annular seal further seals the rear acoustic cavity groove, thereby improving the sound optimization effect; on the other hand, the second annular seal, the inner wall of the speaker receiving groove, and the second sound transmission hole provide a sealed channel for transmitting sound to the external environment, thereby achieving the sealing of the front cavity of the speaker and further improving the audio effect of the speaker assembly.

[0042] In some possible implementations, the shim is a second circuit board, which is electrically connected to the first circuit board;

[0043] The terminal device also includes a camera lens and a rear flash assembly;

[0044] The camera lens is connected to the second end of the camera decorative assembly, and the camera lens has a first rear flash receiving hole;

[0045] One end of the rear flash assembly is located in the first rear flash receiving hole, and a second annular gap is formed between it and the inner wall of the first rear flash receiving hole. The second annular gap is connected to the second sound transmission hole, and the rear flash assembly is electrically connected to the second circuit board.

[0046] In the technical solution provided in this disclosure, the speaker component and the rear flash component can be designed together. The sound emitted by the speaker can be conducted to the external environment through the speaker housing slot, the second sound transmission hole, and the second annular gap. Thus, while realizing sound transmission, there is no need to set an additional sound transmission hole on the secondary display screen, which increases the screen ratio of the secondary display screen and improves the display effect.

[0047] In some possible implementations, the camera decorative assembly has a second rear flash receiving hole, the two ends of which are respectively connected to the first rear flash receiving hole and the second sound transmission hole;

[0048] The rear flash assembly includes a rear flash cover and a rear flash device;

[0049] The first end of the rear flash cover is located in the first rear flash receiving hole and forms a second annular gap with the inner wall of the first rear flash receiving hole. The second end of the rear flash cover is located in the second rear flash receiving hole. The outer wall of the rear flash cover has an annular skirt. The edge of the annular skirt is connected to the inner wall of the second rear flash receiving hole. The annular skirt has a third sound transmission hole.

[0050] The backlight device is located in the space formed between the backlight cover and the second circuit board, and is electrically connected to the second circuit board.

[0051] In the technical solution provided in this disclosure, on the one hand, the terminal device can control the operation of the backlight device through the first circuit board and the second circuit board. The beam emitted by the backlight device can be conducted to the external environment through the backlight cover, thereby realizing the backlight function of the terminal device. On the other hand, the sound emitted by the speaker can be conducted to the external environment through the speaker receiving slot, the second sound transmission hole, the second backlight receiving hole, the third sound transmission hole, and the second annular gap, thereby realizing the conduction of sound.

[0052] The technical solution provided in this disclosure includes at least the following beneficial effects:

[0053] This disclosure provides a terminal device that replaces the battery cover in related technologies with a secondary display screen, avoiding the impact of the battery cover on the screen-to-body ratio of the secondary display screen, thereby increasing the screen-to-body ratio of the secondary display screen. Furthermore, the terminal device includes a support member. When the terminal device is dropped, the camera decorative component transmits the impact force to the mid-frame through the support member, thereby reducing the amplitude of vibration of the camera decorative component and improving its stability. Thus, even if the gap between the camera decorative component and the inner wall of the camera housing hole of the secondary display screen is small, it will not collide with it. This ensures that the secondary display screen has a high screen-to-body ratio while improving the stability and safety of the terminal device.

[0074] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0075] This disclosure provides a terminal device, see [link to relevant documentation] Figure 1 and Figure 2 The terminal device includes a mid-frame 1, a secondary display screen 2, a camera decorative assembly 3, and a support 4; the secondary display screen 2 is located on one side of the mid-frame 1, and its edge is connected to the mid-frame 1; the secondary display screen 2 has a camera receiving hole 21; the camera decorative assembly 3 passes through the camera receiving hole 21, see [reference needed]. Figure 3 and Figure 4 The first end 31 of the camera decorative component 3 is located between the secondary display screen 2 and the middle frame 1, and the second end 32 of the camera decorative component 3 is located on the side of the secondary display screen 2 away from the middle frame 1. The camera decorative component 3 is connected to the display side and / or backlight side of the secondary display screen 2; see also Figure 4 The support member 4 is located between the first end 31 of the camera decorative component 3 and the middle frame 1, and the two ends of the support member 4 are respectively connected to the first end 31 of the camera decorative component 3 and the middle frame 1.

[0076] In implementation, see Figure 1 In this embodiment, the secondary display screen 2 replaces the battery cover (or back cover) of the terminal device in the related technology, avoiding the impact of the presence of the battery cover on the screen ratio of the secondary display screen, thereby achieving the maximum screen ratio of the secondary display screen 2, improving the display effect of the secondary display screen 2, and meeting the user's large screen needs.

[0077] See Figure 2The camera decorative component 3 may have a ring structure, and typically, the camera (or rear camera) of the terminal device is set in the central hole of the ring structure.

[0078] The camera decoration component 3 may include multiple camera decoration parts, and its structure may be set according to installation or disassembly requirements. This disclosure does not limit this aspect.

[0079] See Figure 4 The annular structure of the camera decorative component 3 is located in the camera receiving hole 21. The first end 31 of the camera decorative component 3 is located between the sub-display 2 and the middle frame 1. The first end 31 of the camera decorative component 3 is connected to the middle frame 1 through the support member 4.

[0080] In this way, when the terminal device is dropped, the camera decorative component 3 will transfer the impact force to the middle frame 1 through the support component 4, thereby reducing the amplitude of vibration of the camera decorative component 3 and improving its stability. Thus, even if the gap between the camera decorative component 3 and the inner wall of the camera receiving hole 21 of the secondary display screen 2 (i.e. the edge of the secondary display screen 2) is small, it will not collide with it, thereby ensuring that the secondary display screen 2 has a high screen ratio while improving the stability and safety of the terminal device.

[0081] The second end 32 of the camera decorative component 3 is located on the side of the secondary display screen 2 away from the middle frame 1, that is, it protrudes from the secondary display screen. In this way, the second end 32 of the camera decorative component 3 can serve a decorative purpose and also protect the camera installed in the central hole of its annular structure.

[0082] Understandable Figure 1 The diagram shows a partial structure of a terminal device, and the complete terminal device is not shown. The unshown portion of the terminal device can be any reasonable structure, and this embodiment does not limit it.

[0083] See also some possible implementations. Figure 4 The terminal device also includes a first buffer 5, which is located between the secondary display screen 2 and the first end 31 of the camera decoration assembly 3, and is connected to the backlight side of the secondary display screen 2 and the first end 31 of the camera decoration assembly 3, respectively.

[0084] In practice, the first buffer 5 connects the secondary display screen 2 to the camera decorative assembly 3.

[0085] On the one hand, it improves the stability of the secondary display screen 2. On the other hand, when the terminal device is dropped, the first buffer 5 can further fix the relative position between the secondary display screen 2 and the camera decorative component 3, and alleviate the impact between the two, preventing them from colliding with each other, thereby improving the stability and safety of the terminal device.

[0086] See also some possible implementations. Figure 2 and Figure 4 The camera decorative component 3 has a ring structure that passes through the camera receiving hole 21.

[0087] The support member 4 includes multiple support blocks 41, which are distributed around the annular structure of the camera decorative component 3. The two ends of each support block 41 are connected to the first end 31 of the camera decorative component 3 and the middle frame 1, respectively.

[0088] In this way, multiple support blocks 41 provide multi-faceted support for the camera decorative component 3, thereby improving the stability of the camera decorative component 3 and thus enhancing the stability and security of the terminal device.

[0089] The support block 41 can be made of metal. One end of it is welded to the camera decorative component 3, and the other end is abutted against the middle frame 1 or fixedly connected by other connecting structures (such as adhesive, welding, etc.) to improve its strength and thus improve the stability of the terminal device. Of course, the support block 41 can also be made of other materials with greater strength. This disclosure does not limit this.

[0090] The structure of support block 41 can be any reasonable structure, for example, see Figure 4 The cross-section of the support block 41 can have an L-shaped structure, or other reasonable structures, which are not limited in this embodiment.

[0091] See also some possible implementations. Figure 5 The terminal device also includes a light-emitting component 6, the light-emitting part of which is located between the secondary display screen 2 and the second end 32 of the camera decorative component 3.

[0092] There is a first annular gap 7 between the secondary display screen 2 and the second end 32 of the camera decorative component 3, and the first annular gap 7 is connected to the space where the light-emitting part is located.

[0093] In practice, a black border area is unavoidable at the edge of the camera receiving hole 21 of the secondary display screen 2. Therefore, the light-emitting part of the light-emitting component 6 is placed between the secondary display screen 2 and the second end 32 of the camera decorative component 3. When the light-emitting part of the light-emitting component 6 emits light, its light beam can be conducted from the space where the light-emitting part is located to the first annular gap 7, and then conducted to the external environment through the first annular gap 7, so that the edge of the second end 32 of the camera decorative component 3 will emit light. This light can visually reduce the black border effect of the secondary display screen 2, thereby improving the display effect of the terminal device.

[0094] See also some possible implementations. Figure 5 The camera decorative component 3 has an annular structure that passes through the camera receiving hole 21. The second end 32 of the camera decorative component 3 has a receiving groove 33 on the side near the sub-display 2 that communicates with the first annular gap 7.

[0095] See Figure 5 The light-emitting component 6 includes a light guide ring 61, a flexible circuit board 62, and a light-emitting device 63. The light guide ring 61 is coaxially arranged with the annular structure of the camera decorative component 3 and located within the first annular gap 7. Both sides of the light guide ring 61 are connected to the sub-display screen 2 and the camera decorative component 3, respectively. The first end of the flexible circuit board 62 is located within the receiving groove 33 and connected to the inner wall of the receiving groove 33. The second end of the flexible circuit board 62 is located between the sub-display screen 2 and the middle frame 1, for electrical connection to the motherboard of the terminal device. The light-emitting device 63 is located within the receiving groove 33 and is electrically connected to the flexible circuit board 62.

[0096] In practice, the terminal device can control the light-emitting device 63 to emit light through the flexible circuit board 62. The light beam emitted by the light-emitting device 63 can be conducted to the light guide ring 61 through the connected receiving groove 33 and the first annular gap 7, and then conducted to the external environment from the light guide ring 61, thereby reducing the black border effect of the secondary display screen 2 and improving the display effect of the terminal device.

[0097] See Figure 5 The second end of the flexible circuit board 62 can be electrically connected to the first circuit board 81, which can be the motherboard of the terminal device.

[0098] In some possible implementations, the outer ring portion of the light guide ring 61 is located within the first annular gap 7, and the inner ring portion of the light guide ring 61 is located within the receiving groove 33. The light-emitting device 63 is located between the inner ring portion of the light guide ring 61 and the flexible circuit board 62.

[0099] In practice, the light-emitting device 63 is placed between the inner ring of the light guide ring 61 and the flexible circuit board 62, which avoids the flexible circuit board 62 from blocking the light beam emitted by the light-emitting device 63, thereby improving the light guiding effect of the light guide ring 61 and thus improving the display effect of the terminal device.

[0100] Furthermore, the inner ring of the light guide ring 61 and the light-emitting device 63 are both located within the receiving groove 33. The light beam emitted by the light-emitting device 63 can be directly projected onto the inner ring of the light guide ring 61 and then conducted to the external environment through the light guide ring 61. This improves the light guiding effect of the light guide ring 61 and thus enhances the display effect of the terminal device.

[0101] See also some possible implementations. Figure 6 The terminal device also includes a speaker assembly 8, which is located between the middle frame 1 and the secondary display screen 2 and is connected to the middle frame 1.

[0102] In practice, a speaker assembly 8 is placed between the middle frame 1 and the secondary display screen 2, which can improve the synchronization performance between the sound emitted by the speaker assembly 8 and the image displayed on the secondary display screen 2, thereby improving the user experience of the terminal device.

[0103] Furthermore, the terminal device can also be equipped with multiple other speaker components, which can be located at the top and / or bottom of the terminal device. Speaker component 8, together with other speaker components, can achieve a stereo effect, further improving the usability of the terminal device.

[0104] See also some possible implementations. Figure 6 The middle frame 1 has a rear acoustic cavity 11 on the side near the speaker 83.

[0105] The speaker assembly 8 includes a first circuit board 81, a first annular seal 82, and a speaker 83.

[0106] The first circuit board 81 is located on the side of the middle frame 1 near the secondary display screen 2 and is connected to the middle frame 1. The first circuit board 81 has a first sound transmission hole 811.

[0107] The first circuit board 81 may be the motherboard of the terminal device or other circuit boards electrically connected to the motherboard. This disclosure does not limit the scope of the embodiments.

[0108] The first annular seal 82 is located between the first circuit board 81 and the middle frame 1, and the two ends of the central hole of the first annular seal 82 cover the first sound transmission hole 811 and the rear sound cavity groove 11 respectively. In other words, the orthographic projection of the first sound transmission hole 811 on the plane of the sub-display screen 2 and the orthographic projection of the rear sound cavity groove 11 on the plane of the sub-display screen 2 are both located in the orthographic projection of the central hole of the first annular seal 82 on the plane of the sub-display screen 2.

[0109] The speaker 83 is located on the side of the first circuit board 81 away from the middle frame 1. The speaker 83 is electrically connected to the first circuit board 81 and covers the first sound transmission hole 811.

[0110] In this way, the terminal device can control the speaker 83 to produce sound through the first circuit board 81. The sound wave is transmitted through the first sound transmission hole 811 to the rear sound cavity 11 for sound optimization, making the sound more rounded and full, and then the sound is transmitted outward, thereby improving the audio effect of the speaker assembly.

[0111] The first annular seal 82 can seal the space between the first circuit board 81 and the middle frame 1, that is, seal the rear cavity of the speaker 83, so that the sound waves are prevented from leaking out during the mutual conduction between the speaker 83 and the rear acoustic cavity 11, thereby further improving the audio effect of the speaker assembly.

[0112] See also some possible implementations. Figure 6 The speaker assembly 8 also includes a shim block 84 and a second annular seal 85.

[0113] The shim block 84 is located on the side of the first circuit board 81 away from the middle frame 1 and is connected to the first circuit board 81. The side of the shim block 84 closest to the first circuit board 81 has a speaker receiving groove 841, and the bottom of the speaker receiving groove 841 has a second sound transmission hole 8411. The speaker 83 is located in the speaker receiving groove 841.

[0114] The outer wall of the second annular seal 85 is connected to the speaker receiving groove 841, and the inner wall of the second annular seal 85 is connected to the outer wall of the speaker 83.

[0115] In this way, on the one hand, the second annular seal 85 further seals the rear cavity of the speaker 83, thereby improving the sound optimization effect.

[0116] On the other hand, the second annular seal 85, the inner wall of the speaker receiving groove 841, and the second sound transmission hole 8411 provide a sealed channel for transmitting sound to the external environment, thereby sealing the front cavity of the speaker 83 and further improving the audio effect of the speaker assembly.

[0117] In some possible implementations, the shim block 84 is a second circuit board, which is electrically connected to the first circuit board 81. That is, the shim block 84 itself has a circuit board structure, which can realize the electrical connection function of the circuit board.

[0118] See Figure 6 The terminal device also includes a camera lens 9 and a backflash assembly 10.

[0119] The camera lens 9 is connected to the second end 32 of the camera decorative assembly 3, meaning that the camera lens 9 can be located within the annular structure at the second end of the camera decorative assembly 3 and connected to the inner wall of the annular structure. The camera lens 9 has a first rear flash receiving hole 91.

[0120] One end of the rear flash assembly 10 is located in the first rear flash receiving hole 91, and a second annular gap 911 is formed between it and the inner wall of the first rear flash receiving hole 91. The second annular gap 911 is connected to the second sound transmission hole 8411, and the rear flash assembly 10 is electrically connected to the second circuit board.

[0121] In this way, by designing the speaker assembly 8 and the rear flash assembly 10 together, the sound emitted by the speaker 83 can be conducted to the external environment through the speaker housing slot 841, the second sound transmission hole 8411, and the second annular gap 911, thereby realizing sound conduction.

[0122] Furthermore, while achieving sound transmission, there is no need to set an additional sound transmission hole on the secondary display screen 2, which increases the screen-to-body ratio of the secondary display screen 2 and improves the display effect.

[0123] See also some possible implementations. Figure 6 The camera decorative component 3 has a second rear flash receiving hole 34. The two ends of the second rear flash receiving hole 34 are respectively connected to the first rear flash receiving hole 91 and the second sound transmission hole 8411.

[0124] It is understandable that when the camera decorative component 3 has a ring structure, the second rear flash receiving hole 34 is not connected to the central hole of the ring structure.

[0125] The portion of the camera decorative assembly 3 corresponding to the first end of the second rear flash receiving hole 34 is connected to the camera lens 9, and the two can also be sealed together by the first sealing member (see...). Figure 6 , Figure 6 The first seal is shown.

[0126] The portion of the camera decorative component 3 corresponding to the second end of the second rear flash receiving hole 34 can be connected to the end of the shim block 84 away from the middle frame 1, and the two can also be sealed together by the second seal (see...). Figure 6 , Figure 6 The second seal is also shown.

[0127] The backlight assembly 10 includes a backlight cover 101 and a backlight device 102.

[0128] The first end of the rear flash cover 101 is located in the first rear flash receiving hole 91, and a second annular gap 911 is formed between it and the inner wall of the first rear flash receiving hole 91. The second end of the rear flash cover 101 is located in the second rear flash receiving hole 34. The outer wall of the rear flash cover 101 has an annular skirt 1011. The edge of the annular skirt 1011 is connected to the inner wall of the second rear flash receiving hole 34. The annular skirt 1011 has a third sound transmission hole 1012. In this way, although the connection between the annular skirt 1011 and the inner wall of the second rear flash receiving hole 34 blocks the sound transmission channel, the third sound transmission hole 1012 provided on the annular skirt 1011 transmits the sound. While fixing the rear flash cover 101, it does not affect the sound transmission.

[0129] The backlight device 102 is located in the space formed between the backlight cover 101 and the second circuit board, and is electrically connected to the second circuit board.

[0130] In this way, on the one hand, the terminal device can control the operation of the backlight device 102 through the first circuit board 81 and the second circuit board, and the beam emitted by the backlight device 102 can be transmitted to the external environment through the backlight cover 101, thereby realizing the backlight function of the terminal device.

[0131] On the other hand, the sound emitted by the loudspeaker 83 can be transmitted to the external environment in sequence through the loudspeaker receiving slot 841, the second sound transmission hole 8411, the second rear flash receiving hole 34, the third sound transmission hole 1012, and the second annular gap 911, thereby realizing the transmission of sound.

[0132] The technical solution provided in this disclosure includes at least the following beneficial effects:

[0133] This disclosure provides a terminal device that replaces the battery cover in related technologies with a secondary display screen, avoiding the impact of the battery cover on the screen-to-body ratio of the secondary display screen, thereby increasing the screen-to-body ratio of the secondary display screen 2. Furthermore, the terminal device includes a support member 4. When the terminal device is dropped, the camera decorative component 3 transmits the impact force to the mid-frame 1 through the support member 4, thereby reducing the amplitude of vibration of the camera decorative component 3 and improving its stability. Thus, even if the gap between the camera decorative component 3 and the inner wall of the camera receiving hole 21 of the secondary display screen 2 is small, it will not collide with it, thereby ensuring a high screen-to-body ratio for the secondary display screen while improving the stability and safety of the terminal device.

[0134] The above description is merely an optional embodiment of this disclosure and is not intended to limit this disclosure. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the protection scope of this disclosure.
