TECHNICAL FIELD

This application relates to the field of communications technologies, and in particular, to a mobile terminal.

BACKGROUND

With popularization of intelligent terminals, implementing a higher screen-to-body ratio (a ratio of a display area of a display screen to an area of a front panel of a mobile terminal) has always been a research direction of various mobile phone manufacturers. However, stacking of components such as a camera, a distance detection sensor, an environment detection sensor, and an earpiece on the front top of the screen affects an increase in the screen-to-body ratio. As shown inFIG. 1andFIG. 2,FIG. 2is a sectional view of A-A inFIG. 1. On a mobile terminal, an earpiece3, a part of a sensor4, and a camera5are sequentially stacked in an X direction, and an environment detection sensor6and the earpiece3are sequentially stacked in a Y direction, so that a groove opening2in the middle of a display area on the top of a front screen1of the mobile terminal is relatively long in the X direction and the Y direction. Consequently, a screen-to-body ratio of the mobile terminal is relatively low, and a display effect is affected.

SUMMARY

This application provides a mobile terminal, used to increase a screen-to-body ratio of the mobile terminal.

According to a first aspect, a mobile terminal is provided. The mobile terminal includes a display screen, an earpiece assembly, and a camera. The earpiece assembly includes an earpiece and a sound conduction tube in communication with the earpiece. In addition, in arrangement, a size of the earpiece is greater than a size of the sound conduction tube, so that the earpiece and the sound conduction tube form a stepped structure. The surface that is of the earpiece and that is used to connect to the sound conduction tube is a first stepped surface. In addition, the camera also includes two parts: a body and a lens connected to the body. During disposing, a size of the body is greater than a size of the lens, so that the body and the lens form a stepped structure. A surface that is of the body and that is used to connect to the lens is a second stepped surface.

When the earpiece assembly and the camera are assembled on the display screen, the display screen is provided with a notch. The sound conduction tube and the lens are located in the notch: and in a first direction, the display screen covers a part of the first stepped surface and/or the second stepped surface, where the first direction is a direction perpendicular to a display face of the display screen. Specifically, the covering of the display screen includes: the display screen covers only a part of the first stepped surface, the display screen covers only a part of the second stepped surface, or the display screen covers both a part of the first stepped surface and a part of the second stepped surface.

In the foregoing technical solutions, the earpiece assembly is lowered, so that the earpiece and the display screen are stacked in the first direction, thereby reducing an area that the earpiece occupies on the display screen, reducing a size of the notch, and further increasing a screen-to-body ratio of the mobile terminal.

In a specific implementation solution, to increase the screen-to-body ratio and reduce an opening size of the sound conduction tube, specifically, an opening that is of the sound conduction tube and that is connected to the earpiece is a first opening, an opening that is of the sound conduction tube and that is located on a side of the display surface of the display screen is a second opening, and the sound conduction tube gradually narrows in the first direction. When the sound conduction tube is disposed in a manner of gradually narrowing, the second opening is relatively small, so that an area of the notch can be further reduced, and the screen-to-body ratio of the mobile terminal is increased.

In a specific implementation solution, to further increase the screen-to-body ratio, the sound conduction tube uses a stepped structure, and in the first direction, the display screen covers a part of the sound conduction tube. In this way, the display screen covers the sound hole of the earpiece from above, thereby further reducing the size of the notch and increasing the screen-to-body ratio. In addition, in specific arrangement, the second opening is a circular opening.

In a specific implementation solution, the lens and the sound conduction tube are arranged side by side. In this case, on the display surface of the display screen, a depth direction of the notch is a second direction, and the lens and the sound conduction tube are arranged in a third direction that is perpendicular to the second direction. When the structure is used, in the first direction, the display screen covers a part of the first stepped surface and a part of the second stepped surface. In this way, the area of the notch is further reduced, and the screen-to-body ratio is increased.

In a specific implementation solution, the mobile terminal further includes a sensor assembly, and the sensor assembly is disposed between the sound conduction tube and the lens. A gap between the lens and the sound conduction tube is used to accommodate the sensor assembly, so that space can be fully utilized, and the screen-to-body ratio of the mobile terminal can be further improved.

In a specific implementation solution, the mobile terminal further includes a sensor assembly. The sensor assembly, the lens, and the sound conduction tube are arranged in a shape of an upside-down triangle, and the lens is located below the sound conduction tube in a depth direction of the notch. In addition, during specific disposing, a cover plate is disposed on the display screen of the mobile terminal, a gap located above the sensor assembly is provided on a top of the cover plate, and the gap is in communication with the sound conduction tube.

In a specific implementation solution, the mobile terminal further includes a charging indicator, where the charging indicator is disposed between the sensor assembly and the sound conduction tube.

In a specific implementation solution, locations of the second opening and the first opening are staggered in the first direction for convenience of the disposition of the earpiece.

In a specific implementation solution, a chamfer is provided at a joint between the notch and a side edge of the display screen. Therefore, a size of the notch may be increased on an edge of the display screen, so that arrangement of components is more convenient.

In a specific implementation solution, a middle frame of the mobile terminal and the sound conduction tube are an integrated structure.

In a specific implementation solution, a support structure is further included, where the support structure is provided with an accommodation slot used to accommodate the earpiece, the earpiece is fastened in the accommodation slot, the sound conduction tube and the support structure are an integrated structure, and a through hole in the sound conduction tube is in communication with the accommodation slot.

In a specific implementation solution, the support structure has a support protrusion, and the sensor assembly is fastened to the support protrusion.

In a specific implementation solution, the sound conduction tube is connected to the earpiece in a sealed manner by using sealant, thereby improve a sealing effect.

In a specific implementation solution, the sensor assembly includes an environment detection sensor and a distance detection sensor. Therefore, different signal information can be detected.

It can be learned from the foregoing description that, in the mobile terminal provided in this application, the earpiece assembly and the camera component that occupy relatively large space are disposed in a lowering manner. Only components that occupy relatively small space in the earpiece assembly and in the camera are disposed in the notch, so that a size of the notch can be effectively reduced, thereby improving the screen-to-body ratio of the mobile terminal.

DESCRIPTION OF EMBODIMENTS

To facilitate description of a mobile terminal provided in embodiments of this application, a notch and a stepped structure are first described. The notch mentioned in the embodiments of this application is an opening provided at an edge position of a display screen. When the display screen has a specific thickness, the opening threads through the display screen in a thickness direction of the display screen. The thickness direction of the display screen is a direction perpendicular to a display surface of the display screen. The stepped structure mentioned in the embodiments of this application is a polyhedron structure including at least two layers, and a maximum cross-sectional area of each layer of polyhedron structure gradually decreases in a specific direction. A polyhedron structure with a larger maximum cross-sectional area in two adjacent polyhedron structures is referred to as a bottom layer, and a polyhedron structure with a smaller maximum cross-sectional area is referred to as a top layer. A surface on which a bottom-layer polyhedron structure is connected to a top-layer polyhedron structure is referred to as a stepped surface; or a visible surface in an area from a maximum cross section of a bottom-layer polyhedron structure to a surface on which the bottom-layer polyhedron structure is connected to a top-layer polyhedron structure is referred to as a stepped surface.

In the embodiments of this application, to increase a screen-to-body ratio of a mobile terminal, a mobile terminal is provided. In the mobile terminal, disposing positions of a camera and an earpiece assembly are improved, so that an area of a part that is of the camera and the earpiece assembly and that is exposed outside a display screen is reduced, thereby reducing a size of a notch on the display screen. When the notch (a non-display area) on the display screen decreases, a display area can be correspondingly increased. It can be learned from a formula: screen-to-body ratio of the mobile terminal=display area of the display screen/front panel area of the mobile terminal that the screen-to-body ratio of the display screen on the mobile terminal may be improved by reducing an area of the notch.

For ease of describing structures of the camera and the earpiece assembly and locations of the camera and the earpiece assembly relative to the display screen provided in the embodiments of this application, as shown inFIG. 3andFIG. 4,FIG. 3is a schematic diagram of a part of the mobile terminal according to the embodiments of this application, andFIG. 4is a sectional view of B-B inFIG. 3. First, directions on a display screen10are set to a first direction, a second direction, and a third direction respectively. The first direction is a direction perpendicular to a display surface of the display screen10, namely a thickness direction of the display screen10; the second direction is a depth direction that is of a notch11on the display screen10and that is on the display surface; and the third direction is a direction perpendicular to the second direction on the display surface. In addition, the display surface of the display screen10is defined, and the display surface is a surface that is of the display screen10and that is exposed outside the mobile terminal, and is used to display an image.

As shown inFIG. 3,FIG. 3shows a structure of a mobile terminal according to an embodiment of this application. The mobile terminal includes the display screen10, an earpiece assembly20, and a camera40. During disposing, the earpiece assembly20and the camera40are disposed side by side on a side that is of the display screen10and that is opposite to the display surface. In addition, when the earpiece assembly20and the camera40are assembled with the display screen10, as shown inFIG. 4, the display screen10and the earpiece assembly20, and the display screen10and the camera40are disposed in a stacked manner in the first direction. To improve the screen-to-body ratio of the mobile terminal, in the mobile terminal provided in this embodiment of this application, the display screen10covers a part of the earpiece assembly20or a part of the camera40for implementation. For ease of understanding, the following describes in detail a cooperation relationship between the display screen10, the earpiece assembly20, and the camera40provided in this embodiment of this application.

First, for the earpiece assembly20, to improve the screen-to-body ratio of the mobile terminal, two components are used for the earpiece assembly20: an earpiece22and a sound conduction tube21connected to the earpiece22. During disposing, the sound conduction tube21and the earpiece22are arranged in the first direction. With reference toFIG. 4andFIG. 5,FIG. 5is a schematic diagram of disposing a position of the earpiece assembly20relative to the display screen10. In a structure shown inFIG. 5, a cross section b is a cross section that is of the sound conduction tube21and that is perpendicular to the first direction, and a cross section a is a cross section that is of the earpiece22and that is perpendicular to the first direction. It can be learned fromFIG. 5that an area of the cross section b is less than an area of the cross section a, and a stepped structure is formed after the sound conduction tube21and the earpiece22are assembled. A surface that is on the earpiece22and that is used to connect to the sound conduction tube21is a first stepped surface221, and the first stepped surface221may be a flat surface, a curved surface, or an irregular surface. When the earpiece assembly20is assembled with the display screen10, the earpiece22is disposed in a lowering manner. Specifically, the earpiece22is located outside the notch11, the sound conduction tube21is inserted into the notch11, and the display screen10covers a part of the earpiece22. Referring toFIG. 5, it can be learned fromFIG. 5that the earpiece22is located on a side that is of the display screen10and that is opposite to the display surface, and the display screen10covers a part of the first stepped surface221. In this disposing manner, because only the sound conduction tube21in the earpiece assembly20is inserted into the notch11, a size of only the sound conduction tube21affects the notch11, and a size of the earpiece22does not affect the size of the notch11on the display screen10. When the sound conduction tube21is disposed, it can be learned fromFIG. 5that the area of the cross section b of the sound conduction tube21is less than the area of the cross section a of the earpiece22. Therefore, on a premise that a size of another component accommodated in the notch11remains unchanged, a size of the notch11that accommodates the sound conduction tube21is less than a size of the notch11that accommodates the earpiece22in the prior art. On the premise that sizes of a front-end surface and the display screen10of the mobile terminal remain unchanged, reduction of the notch11is equivalent to an increase in a display area of the display screen10, thereby increasing the screen-to-body ratio of the mobile terminal.

Second, for the camera40, a stepped structure is also used. The camera40includes two parts: a body42and a lens41. With reference toFIG. 4andFIG. 7,FIG. 7is a schematic diagram of a position of the lens41relative to the display screen10. A cross section c is a cross section that is of the body42and that is perpendicular to the first direction, and a cross section d is a cross section that is of the lens41and that is perpendicular to the first direction. It can be learned fromFIG. 7that an area of the cross section c is greater than an area of the cross section d, thereby forming a stepped structure. In the formed stepped structure, a surface that is on the body42and that is used to connect to the lens41is a second stepped surface421, and the second stepped surface421may be a flat surface, a curved surface, or an irregular surface. During assembly, as shown inFIG. 7, the body42is located on a side that is of the display screen10and that is opposite to the display surface, and the lens41is inserted into the notch11of the display screen10. To improve the screen-to-body ratio of the mobile terminal, when the camera40is disposed, the display screen10covers a part of the body42. That is, the display screen10shown inFIG. 7covers a part of the second stepped surface421. A disposing manner is similar to the disposing manner of the earpiece assembly20. For a specific disposing manner of the camera40, refer to the foregoing disposing manner of disposing the earpiece assembly20.

When the foregoing assembly manner is used, it can be learned that by lowering the camera40and the earpiece assembly20, the body42and the earpiece22that are of relatively large sizes are located outside the notch11, and only the sound conduction tube21and the lens41that are of relatively small sizes are disposed in the notch11, so that an opening area of the notch11is effectively reduced, thereby increasing the screen-to-body ratio of the mobile terminal. It should be understood that the foregoing lists an example in which the display screen10covers a part of the first stepped surface221and a part of the second stepped surface421, but the following structure may also be used to reduce an area of the notch11. For example, only a part or all of the first stepped surface221is covered, or only a part or all of the second stepped surface421is covered. Compared with the display screen in the prior art, the area of the notch11may also be reduced by using the foregoing two listed manners, and the screen-to-body ratio of the mobile terminal is increased. Therefore, it can be learned from the foregoing description that, in the display screen10provided in this embodiment of this application, when the display screen10covers a structure of a part of the first stepped surface221and/or a part of the second stepped surface421, the screen-to-body ratio of the mobile terminal can be increased. That the display screen10covers a part of the first stepped surface221and/or a part of the second stepped surface421may be explained as follows: the display screen10covers only a part or all of the first stepped surface221, or the display screen10covers only a part or all of the second stepped surface421; or the display screen10covers a part or all of the first stepped surface221and a part or all of the second stepped surface421at the same time.

When the sound conduction tube21is specifically involved, to further increase the screen-to-body ratio of the mobile terminal, the sound conduction tube21in this embodiment of this application uses a structure that gradually narrows in the first direction. As shown inFIG. 4andFIG. 5, a cross-sectional area of the sound conduction tube21gradually decreases in a direction from the earpiece22to the notch11. For ease of description, a first opening and a second opening211of the sound conduction tube21are defined, where the first opening is an opening connecting the sound conduction tube21and the earpiece22, and the second opening211is an opening that is of the sound conduction tube21and that is located on a side of the display surface of the display screen10. The second opening211is an opening through which the sound conduction tube21is inserted into the notch11. In this embodiment of this application, to reduce an area that the sound conduction tube21occupies in the notch11, a manner in which the second opening211is smaller than the first opening is used. It can be learned fromFIG. 4that the second opening211is approximately parallel to the display surface of the display screen10. Therefore, when the second opening211is minimized, the area that the second opening211occupies in the notch11is also reduced, so that the display area of the display screen10can be increased, and the screen-to-body ratio of the mobile terminal can be increased. When the sound conduction tube21is disposed, a shape of the sound conduction tube21is not limited, provided that a sound loss is less than a set value when the sound conduction tube21transmits a sound. The set value may be set according to an actual production requirement. Specifically, a structure of the sound conduction tube21may be shown inFIG. 5. The sound conduction tube21uses a stepped structure. A part that is of the sound conduction tube21and that is connected to the earpiece22has a relatively large cross-sectional area, and a part that is of the sound conduction tube21and that is located in the notch11has a relatively small cross-sectional area. When the structure is used, in a first direction, the display screen10covers a part of the sound conduction tube21to avoid inserting a sound conduction tube with a relatively large area into the notch11, and a position of the earpiece22may be flexibly disposed.

In addition, in a specific implementation solution, when the sound conduction tube21is disposed, the sound conduction tube21may be disposed in a manner in which a center line of the second opening211deviates from a center line of a sound outlet hole of the earpiece22. In this case, positions of the second opening211and the first opening are staggered in the first direction. In a specific deviation, as shown inFIG. 5, the second opening211deviates from sound outlet hole in a direction facing the disposed camera40, so that the second opening211can be closer to the lens41. In this case, a gap between the sound conduction tube21and the lens41that are in the notch11is reduced, so that the area of the notch11may be further reduced, and the display screen10may cover more part of the earpiece22, thereby facilitating arrangement of the earpiece22.

Certainly, a structure of the sound conduction tube21is not limited to the foregoing described stepped structure or a disposing manner of deviating from the earpiece center, and a structure in a shape of a straight tube shown inFIG. 6may also be used. When the structure in the shape of a straight tube inFIG. 6is used, the size of the notch11may also be reduced.

When the camera40and the earpiece assembly20are specifically disposed, as shown inFIG. 4, the lens41and the sound conduction tube21are arranged side by side. In this case, on the display surface of the display screen10, the lens41and the sound conduction tube21are arranged in a third direction. When the structure is used, in the first direction, the display screen10covers a part of the first stepped surface221and a part of the second stepped surface421. Therefore, the area of the notch11is further reduced, and the screen-to-body ratio is increased. In addition, the earpiece assembly20and the camera40are arranged in the third direction, so that a depth of the notch11on the display surface can be reduced. When the structure is used, as shown inFIG. 3, a corresponding notch11on the display screen10is a rectangular notch11. A length in the second direction is less than a length in the third direction, to reduce impact of the notch11on the display area.

In addition, the mobile terminal provided in this embodiment of this application further includes a sensor assembly30, and the sensor assembly30may be an environment detection sensor, a distance detector, a tri-color light, or another common sensor assembly30. When the sensor assembly30is assembled in the notch11, the sensor assembly30is disposed in the gap between the sound conduction tube21and the lens41. In this way, the gap formed between the lens41and the earpiece22is fully utilized, and no additional space is occupied. When the lens41, the sensor assembly30, and the sound conduction tube21are specifically disposed, as shown inFIG. 1, in the third direction, the lens41, the sensor assembly30, and the sound conduction tube21are arranged in a single row. Therefore, a length occupied in the second direction is reduced, equivalent to reducing a depth of the notch11on the display surface, thereby reducing impact on a display effect of the display screen10.

When the earpiece assembly20and the camera40are specifically assembled, the camera40and the earpiece assembly20are fastened by using a structure on a middle frame60. Referring toFIG. 4, it can be learned fromFIG. 4that, in the first direction, a glass cover plate50, the display screen10, and the middle frame60are sequentially disposed in a structure of the mobile terminal from top to bottom. When the sound conduction tube21is specifically disposed, the sound conduction tube21uses a structure integrated with the middle frame60. In this case, a sound conduction groove is formed on the structure of the middle frame60, and the sound conduction groove is directly formed on the middle frame60during preparation. When the earpiece22is assembled, the gap between the sound conduction groove and the earpiece22is sealed by using foam, to improve a sound propagation effect. When the earpiece22and the camera40are specifically assembled, a support structure is disposed on the middle frame60, and an accommodation slot for accommodating the earpiece22is provided on the support structure. In addition, the sound conduction tube21and the support structure are an integrated structure. In this case, a through hole in the sound conduction tube21is in communication with the accommodating slot, that is, the sound conduction groove is provided on the support structure and is in communication with the accommodation slot. When the earpiece22is assembled, the earpiece22may be directly fastened in the accommodation slot, to implement communication between the sound conduction groove and the earpiece22. When the sensor assembly30is disposed, the support structure has a support protrusion, and the sensor assembly30is fastened to the support protrusion, thereby fastening the sensor assembly30.

It can be learned from the foregoing embodiment that the camera40and the earpiece assembly20provided in this embodiment of this application use the stepped structure. In addition, when assembled with the display screen10, components with relatively large sizes in the earpiece assembly20and the camera40are lowered, so that the component with a relatively small size is disposed inside the notch11. Therefore, an opening area of the notch11is reduced, and the display area of the display screen10is increased, thereby increasing the screen-to-body ratio of the mobile terminal.

Certainly, it should be understood that, arranging the foregoing listed lens41, the sound conduction tube21, and the sensor assembly30in a third direction is a specific disposing manner. The mobile terminal provided in this embodiment of this application may alternatively use another arrangement manner to increase the screen-to-body ratio of the mobile terminal. Another arrangement manner is listed below to further describe the mobile terminal provided in this embodiment of this application.

As shown inFIG. 8andFIG. 9, first, components included in a mobile terminal shown inFIG. 8include a display screen10provided with a notch11, an earpiece assembly20, and a camera40, and both the earpiece assembly20and the camera40use the stepped structure described above. In the structure shown inFIG. 8, the display screen10covers a part of a first stepped surface221and a part of a second stepped surface421, thereby further reducing an area of the notch11.

During specific disposing, the notch11is located in the middle of the top of the display screen10, and is a U-shaped notch11. The sensor assembly30, the lens41, and the sound conduction tube21are arranged in a shape of an upside-down triangle. The lens41is located below the sound conduction tube21in a depth direction of the notch11. Still referring toFIG. 8andFIG. 9, with a disposing direction of the display screen10shown inFIG. 8as a reference direction, the lens41is located at the bottom, the sensor assembly30is at an upper left corner of the lens41, and the sound conduction tube21is at an upper right corner of the lens41, thereby forming a structure of an upside-down triangle. As shown inFIG. 10, the sound conduction tube21is disposed in a water bag-shaped structure, and a second opening211of the sound conduction tube21is located outside the earpiece22. In this case, positions of the second opening211and a first opening are staggered in the first direction. In addition, a sound outlet hole in communication with the sound conduction tube21is provided on the glass cover plate, and the sound outlet hole is located above the sensor assembly30and located at a top position of the display screen10.

When the structure of an upside-down triangle is used during disposing, both the sensor assembly30and the sound conduction tube21are partially located in a gap of the stepped structure of the camera40, so that in the first direction, the sensor assembly30and the body42of the camera40partially overlap, and the sound conduction tube21and the body42of the camera40partially overlap, thereby minimizing an area that the foregoing components occupies in the notch11.

When the notch11is specifically disposed, referring to the structure inFIG. 8, two arc-shaped chamfer structures are provided at a joint between a side wall of the notch11and a side edge of the display screen10, so that the side wall of the notch11can be attached to an edge of the lens41, and a position of the formed chamfer structure can increase the size of an opening end of the notch, thereby accommodating the sensor assembly30and the earpiece assembly20. When this structure is used, a size of a conventional notch11can be reduced, and the screen-to-body ratio of the mobile terminal can be increased.

It can be learned from the foregoing description that when the structure is used, a width in the third direction can be well controlled, and a depth in the second direction is only slightly greater than a diameter of the lens41.

In addition, the mobile terminal provided in this embodiment of this application further includes a charging indicator70, and the charging indicator70is disposed between the sensor assembly30and the sound conduction tube21.

When the sound conduction tube21is specifically disposed, the foregoing manner in which the sound conduction tube21and the middle frame are an integrated structure may be used. For specific description, refer to the description of the embodiment corresponding toFIG. 4. Details are not described herein again.

It can be learned from the foregoing embodiment that, the camera40and the earpiece assembly20use a stepped structure, and when assembled with the display screen10, components with relatively large sizes in the earpiece assembly20and the camera40are lowered, so that a component with a relatively small size is disposed inside the notch11. Therefore, regardless of an arrangement manner, the opening area of the notch11can be reduced, so that the display area of the display screen10can be increased, thereby improving an effect of a screen-to-body ratio of the mobile terminal.
