TECHNICAL FIELD

[0001] The present application relates to the terminal field, and in particular to an electronic device and a cover. BACKGROUND

[0002] At present, users have higher and higher requirements on the appearance of electronic devices. In some technical solutions, a gap is formed between a main body and a display screen assembly in an electronic device, and the gap is generally shielded by setting a cover.

[0003] In addition, an acoustic cavity is formed in the main body of the electronic device, and an audio output channel is needed to be formed on the electronic device to communicate the acoustic cavity with the outside of the electronic device in order to realize the audio playing function of the electronic device. However, the audio output channel formed on the main body will affect the mechanical performance of the main body. Therefore, how to set the audio output channel on the electronic device has become a problem to be solved in the technical field of electronic devices. SUMMARY

[0004] Therefore, the embodiments of the present application provide an electronic device and a cover. The electronic device includes the cover, a display screen assembly and a main body. The cover includes a first part and a second part. The display screen assembly is supported on the main body and forms a gap. The cover is used to shield the gap. The first part covers at least part of the edge of the display screen assembly. The second part extends from the first part to the main body and can be installed on the main body through the gap. The main body includes an acoustic cavity. The cover and / or the main body is provided with an audio output channel which communicates the acoustic cavity with the outside of the electronic device. The area of the audio outlet in the lateral projection plane is greater than 0. The lateral projection plane is perpendicular to the plane where the display screen assembly is located and parallel to the edge of the display screen assembly corresponding to the audio output channel. The electronic device can improve the appearance and the mechanical performance of the cover without increasing the size of the first part. Therefore, the size of the display screen assembly can be increased, and the space utilization of the electronic device can be improved.

[0005] The first aspect of the present application provides an electronic device, wherein the electronic device comprises a main body, a display screen assembly and a cover. A plane on which the display screen assembly is located is a first projection plane. The main body comprises a support surface, and the display screen assembly is supported on the support surface of the main body. The cover comprises a first part and a second part connected to the first part. The first part covers at least part of the edge of the display screen assembly, and the orthographic projection of the first part in the first projection plane at least partially coincides with the orthographic projection of the edge of the display screen assembly in the first projection plane. The second part extends from the first part in a direction pointing to the main body and is connected to the main body. The inside of the main body comprises an acoustic cavity, and the cover and / or the main body enclose an acoustic outlet channel. The acoustic outlet of the acoustic outlet channel communicates with the outside of the electronic device, and the acoustic inlet of the acoustic outlet channel communicates with the acoustic cavity. Moreover, the area of the orthographic projection of the acoustic outlet of the acoustic outlet channel in a second projection plane is greater than 0. The second projection plane is perpendicular to the first projection plane, and the edge of the display screen assembly corresponding to the acoustic outlet of the acoustic outlet channel is parallel to the second projection plane.

[0006] The electronic device includes but is not limited to any one of the following electronic products: a mobile phone, a tablet computer, a notebook computer, a vehicle-mounted computer, an electronic reader, a wearable electronic device, etc. The gap between the display screen assembly and the main body refers to the gap observed between the display screen assembly and the main body when a user observes the electronic device from the side on which the display screen assembly is located.

[0007] In the above electronic device, on the one hand, the user will not observe the acoustic outlet channel and other internal components when observing the electronic device from the side on which the display screen assembly is located, thereby improving the appearance. On the other hand, the mechanical performance of the cover can be ensured without increasing the size of the first part. Therefore, the size of the display screen assembly can be increased, and the space utilization rate of the electronic device can be improved.

[0008] In some possible implementations of the above first aspect, the ratio of the area of the orthographic projection of the acoustic outlet of the acoustic outlet channel in the first projection plane to the area of the orthographic projection of the acoustic outlet of the acoustic outlet channel in the second projection plane is a positive-to-side ratio parameter, and the positive-to-side ratio parameter is less than or equal to 1. That is, the area of the orthographic projection of the acoustic outlet of the acoustic outlet channel in the first projection plane is greater than the area of the orthographic projection of the acoustic outlet of the acoustic outlet channel in the second projection plane.

[0009] For example, the positive-to-side ratio parameter can be at least one of 0, 0.05, 0.1, 0.15, 0.2, 0.25, 0.3, 0.35, 0.4, 0.45, 0.5, 0.55, 0.6, 0.65, 0.7, 0.75, 0.8, 0.85, 0.9, 0.95, 1.0.

[0010] The area of the orthographic projection of the sound outlet of the sound outlet channel in the first projection plane is greater than the area of the orthographic projection of the sound outlet of the sound outlet channel in the second projection plane, weakening the visual effect of the sound outlet of the sound outlet channel on the front surface and further improving the appearance of the electronic device.

[0011] In some possible implementation manners of the first aspect, the sound outlet of the sound outlet channel is arranged on the cover and the main body. That is, the sound outlet of the sound outlet channel is jointly formed by the cover and the main body.

[0012] For example, the first sound outlet gap is arranged on the cover, and the first sound outlet gap and the surface of the main body jointly form the sound outlet of the sound outlet channel. For another example, the second sound outlet gap is arranged on the main body, and the second sound outlet gap and the surface of the cover jointly form the sound outlet of the sound outlet channel. For yet another example, the first sound outlet gap is arranged on the cover, and the second sound outlet gap is arranged on the main body, and the first sound outlet gap and the second sound outlet gap jointly form the sound outlet of the sound outlet channel.

[0013] The electronic device only needs to arrange a gap on the cover and / or the main body to form the sound outlet of the sound outlet channel, and the overall processing difficulty is relatively low, the cover and the main body are prevented from forming a small-size structure, and the structural strength of the cover and the main body is improved. In addition, for the technology in which the first sound outlet gap is arranged on the cover and the first sound outlet gap and the surface of the main body jointly form the sound outlet of the sound outlet channel, only the gap needs to be arranged on the cover, and no gap or hole needs to be additionally arranged on the main body, so that the mechanical performance of the main body can be ensured, and the overall strength of the electronic device is improved.

[0014] In some possible implementation manners of the first aspect, the sound outlet channel includes a first sub-sound outlet channel, and the second part includes a first side plate, and the first side plate is provided with a first through hole, the first through hole is in communication with the sound cavity, and the first through hole constitutes the first sub-sound outlet channel.

[0015] The electronic device is provided with the first sub-sound outlet channel, the sound inlet of the first sub-sound outlet channel is in communication with the sound cavity, and the first sub-sound outlet channel is arranged on the first side plate in the second part. That is, the sound inlet of the first sub-sound outlet channel is arranged on the surface of the first side plate, so that the sound inlet of the first sub-sound outlet channel can be ensured to be in communication with the sound cavity when the mobile phone is switched between the folded state, the unfolded state and the intermediate state, and thus the loudspeaker module can be ensured to work normally in each state of the electronic device.

[0016] In some possible implementation manners of the first aspect, the sound outlet channel further includes a second sub-sound outlet channel, and the second sub-sound outlet channel is in communication with the first sub-sound outlet channel. The display screen assembly is located on one side of the first side plate along a first direction, and the first direction is parallel to the first projection surface. The main body includes a second side plate, and the second side plate is located on the other side of the first side plate along the first direction. A gap is formed between the first side plate and the second side plate, and the gap constitutes the second sub-sound outlet channel. In addition, the second side plate blocks the sound outlet of the first sub-sound outlet channel along the first direction.

[0017] In some possible implementation manners of the present application, the main body includes a middle frame, and the middle frame includes a second side plate. A gap is formed between the second side plate and the screen display assembly, and the cover can be used to block the gap between the second side plate and the screen display assembly. The second side plate is located on the other side of the first side plate along the first direction. A gap is formed between the first side plate and the second side plate, and the gap constitutes the second sub-sound outlet channel. In addition, the second side plate blocks the sound outlet of the first sub-sound outlet channel along the first direction.

[0018] In the electronic device, the second sub-sound outlet channel in communication with the first sub-sound outlet channel is a gap between the first side plate in the first part and the second side plate in the main body, the processing technology of the second sub-sound outlet channel is simple, and the production cost is reduced.

That is, when the inside of the electronic device is observed from the outside to the inside, the internal structure of the electronic device cannot be seen at any angle, and the appearance of the electronic device is further improved.

[0021] In some possible implementation manners of the first aspect, a first notch is arranged on the surface of the second side plate opposite to the first side plate, and the first notch is aligned with the second sub-sound outlet channel along the first direction.

[0023] In some possible implementation manners of the first aspect, the sound outlet channel further includes a third sub-sound outlet channel, a gap is formed between the first part and the second side plate, and the gap constitutes the third sub-sound outlet channel. The first part blocks the sound outlet of the second sub-sound outlet channel along a second direction, and the second direction is perpendicular to the first projection surface.

[0024] The third sub-sound outlet channel in communication with the second sub-sound outlet channel is a gap between the first part and the second side plate of the main body, and the third sub-sound outlet channel has a simple processing process and reduces production costs. In addition, the sound outlet of the second sub-sound outlet channel is shielded by the first part, so that the user cannot observe the first sub-sound outlet channel and the second sub-sound outlet channel from the outside, and the appearance of the electronic device is further beautified.

[0025] In some possible implementation manners of the first aspect, a surface of the first part opposite to the second side plate is provided with a second notch, and the second notch is aligned with the second sub-sound outlet channel in the second direction.

[0027] In some possible implementation manners of the first aspect, the second part further includes a reinforcing part. The reinforcing part is arranged in the first sub-sound outlet channel and is connected to the surface opposite to the first sub-sound outlet channel, respectively.

[0028] In the electronic device, the reinforcing part is additionally arranged in the first sub-sound outlet channel, so that the area with weak mechanical properties in the cover is improved, and the overall mechanical properties of the cover are improved.

[0029] In some possible implementation manners of the present application, the arrangement area of the sound outlet channel in the cover is the same as the area connected to the main body in the cover.

[0030] In some possible implementation manners of the first aspect, the sound outlet of the sound outlet channel is arranged on the cover. In the electronic device, the sound outlet of the sound outlet channel is arranged on the cover, so that the main body does not need to be additionally provided with a notch or a hole, the mechanical properties of the main body are ensured, and the overall strength of the electronic device is improved.

[0032] In some possible implementation manners of the first aspect, the electronic device is a foldable electronic device. The electronic device can be in a flat state, a folded state and an intermediate state. The intermediate state, which can also be referred to as a hovering state (or a rotating state), can be any state between the flat state and the folded state. It can be understood that the foldable electronic device in the present application can be an inward folding device, that is, the display screen assembly of the mobile phone is located on the inner side of the main body in the folded state. The foldable electronic device in the present application can also be an outward folding device, that is, the display screen assembly of the mobile phone is located on the outer side of the main body in the folded state. The present application does not make specific limitations in this regard.

[0033] In some possible implementation forms of the first aspect, the sound inlet of the sound outlet channel is arranged on a surface of the second part facing the display screen assembly.

[0034] That is, in the present application, when the electronic device is switched from the folded state to the unfolded state, or when the electronic device is switched from the unfolded state to the folded state, the edge of the display screen assembly parallel to the rotation shaft mechanism slides relative to the corresponding cover in the first direction, and the distance between the display screen assembly and the second part changes when the electronic device is switched between the folded state and the unfolded state. Compared with the unfolded state, in the intermediate state and the folded state, the edge of the display screen assembly parallel to the rotation shaft mechanism slides towards the corresponding cover. In order to ensure the normal use of the sound outlet channel in the intermediate state and the unfolded state, it is necessary to ensure that the sound inlet of the sound outlet channel is in communication with the sound cavity in the two states.

[0070] For the purposes of the present application, the technical solutions and advantages thereof will be further described in detail below with reference to the drawings.

[0071] The present application provides an electronic device, which includes but is not limited to any one of the following electronic products: a mobile phone, a tablet computer, a notebook computer, a vehicle-mounted computer, an electronic reader, a wearable electronic device, etc. For ease of description, the following will take the electronic device as a mobile phone as an example for description.

[0072] The specific structure of the mobile phone will be described in detail below with reference to the drawings.

[0073] Before introducing the specific structure of the mobile phone, for ease of description, the x-axis, y-axis and z-axis in the mobile phone are defined first. The x-axis and y-axis are parallel to the display screen assembly of the mobile phone, the x-axis can be directed from the bottom of the mobile phone (e.g. the end of the mobile phone where the charging port is located) to the top of the mobile phone (e.g. the end of the mobile phone where the camera is located), the y-axis intersects the x-axis, and the z-axis is in the thickness direction of the mobile phone. In addition, the plane where the display screen assembly is located is defined as the first projection plane, and the plane which is perpendicular to the first projection plane and parallel to the edge of the display screen assembly corresponding to the sound outlet channel is defined as the second projection plane. It can be found that the first projection plane can be a plane, and the second projection plane can be a plane, a curved surface, a folded surface, etc., which are not specifically limited in the present application.

[0074] It can be understood that the mutual parallelism in the present application is not absolute parallelism, and the approximate parallelism (e.g. the included angle between two structural features is 181°, 179.8°, 179°, 178°, etc.) caused by factors such as machining errors and assembly errors is also within the range of mutual parallelism in the present application. The limitation of mutual parallelism will not be repeatedly described hereinafter. The mutual perpendicularity in the present application is not absolute perpendicularity, and the approximate perpendicularity (e.g. the included angle between two structural features is 92°, 89.9°, 89°, 88°, etc.) caused by factors such as machining errors and assembly errors is also within the range of mutual perpendicularity in the present application. The limitation of mutual perpendicularity will not be repeatedly described hereinafter.

[0075] In some embodiments of the present application, the x-axis direction, the y-axis direction and the z-axis direction are mutually perpendicular.

[0076] Figure 1 An exploded view of the mobile phone 1 in some embodiments of the present application is shown. Fig. 2(a) shows a top view of the mobile phone 1 in some embodiments of the present application. Fig. 2(b) shows a partial enlarged view of the mobile phone 1 in the S1 region of Fig. 2(a) in some embodiments of the present application, wherein the cover is not shown in the figure. Fig. 2(c) shows a partial enlarged view of the mobile phone 1 in the S1 region of Fig. 2(a) in some embodiments of the present application. Figure 3 A sectional view of the mobile phone 1 along the M-M section of Fig. 2(a) in some embodiments of the present application is shown. In combination with Figures 1 to 3 It can be seen that the mobile phone 1 in the present application comprises a cover 100, a display screen assembly 200 and a main body 300.

[0077] In some embodiments of the present application, a gap is formed between the display screen assembly 200 and the main body 300.

[0078] In the present application, the gap formed between the display screen assembly 200 and the main body 300 refers to the gap observed between the display screen assembly 200 and the main body 300 when a user observes the mobile phone 1 from the side where the display screen assembly 200 is located. For example, as shown in Fig. 2(b), the gap observed between the display screen assembly 200 and the main body 300 when a user observes the mobile phone 1 from the side where the display screen assembly 200 is located can be the gap Gap. It can be understood that the gap formed between the display screen assembly 200 and the main body 300 will not be repeated in the following. In combination with Fig. 2(b) and Fig. 2(c), it can be seen that the cover 100 covers at least part of the display screen assembly 200 and the main body 300, covering the gap Gap between the display screen assembly 200 and the main body 300, so that the appearance of the mobile phone 1 is more beautiful.

[0079] In order to solve the technical problem of how to set the sound outlet channel, the present application provides a mobile phone 1a, wherein a sound outlet channel 500a is formed on the cover 100a of the mobile phone 1a. The following will be described in detail in combination with Figure 4 .

[0080] Figure 4 A partial enlarged view of the mobile phone 1a in some embodiments of the present application in the S2 region of Figure 3 is shown.

[0081] As Figure 4As shown, in some embodiments of the present application, the mobile phone 1a comprises a cover 100a, a display screen assembly 200 and a main body 300. The cover 100a comprises a first part 110a and a second part 120a. The display screen assembly 200 is supported on the main body 300, and a gap (not shown) is formed between the display screen assembly 200 and the main body 300. The first part 110a of the cover 100a covers at least part of the edge of the display screen assembly 200, and the orthographic projection of the first part 110a in a first projection plane at least partially coincides with the orthographic projection of the edge of the display screen assembly 200 in the first projection plane. The second part 120a of the cover 100a extends from the first part 110a towards the main body 300, and is mounted on the main body 300 through the gap. The main body 300 comprises an acoustic cavity 400, and the cover 100a comprises a sound outlet channel 500a. The sound outlet channel 500a is in communication with the acoustic cavity 400 and the outside of the mobile phone 1a. The area of the orthographic projection of the sound outlet port 501a of the sound outlet channel 500a in a second projection plane is 0. Figure 4 It can be seen that the sound outlet port 501a of the sound outlet channel 500a is formed on the first cover surface 101a of the cover 100a. The first cover surface 101a is a surface of the first part 110a that faces away from the display screen assembly 200 and is parallel to the first projection plane, and will not be described below. In other words, the first cover surface 101a is a surface of the first part 110a that can be directly observed when the mobile phone 1a is viewed from the side of the display screen assembly 200.

[0082] It can be understood that in the present application, the sound outlet port refers to the port on the side of the sound outlet channel that is away from the acoustic cavity 400, and the sound inlet port refers to the port on the side of the sound outlet channel that is close to the acoustic cavity 400, which will not be repeated below. For example, a sound outlet channel comprises a first port and a second port, wherein the first port is connected to the outside, and the second port is connected to the acoustic cavity, and the first port is the sound outlet port, and the second port is the sound inlet port. The concept of the sound outlet port and the sound inlet port will not be repeated below.

[0083] Figure 5 Fig. 2(a) shows a partial enlarged view of the S1 region of the mobile phone 1a in some embodiments of the present application. Figure 6 Fig. 2(b) shows a partial enlarged view of the S1 region of the mobile phone 1a in some embodiments of the present application.

[0084] According to Figure 4 , Figure 5 and Figure 6It is not difficult to see that since the sound channel 500a is opened on the first portion 110a in the cover 100a, and the sound outlet 501a of the sound channel 500a is opened on the first cover surface 101a of the first portion 110a, when the user observes the mobile phone 1a from the side where the display assembly 200 is located, the sound outlet 501a of the sound channel 500a can be observed. In some application scenarios, other components inside the mobile phone 1a can even be observed through the sound outlet 501a.

[0085] In the aforementioned mobile phone 1a, when a sound channel 500a is opened on the first portion 110a in the cover 100a, and the sound outlet 501a of the sound channel 500a is opened on the first cover surface 101a of the first portion 110a, on the one hand, when the user observes the mobile phone 1a from the side where the display assembly 200 is located, the sound outlet 501a of the sound channel 500a can be observed, and other internal components of the mobile phone 1a can be observed through the sound outlet 501a, resulting in poor aesthetics of the mobile phone 1a. On the other hand, the size of the first portion 110a needs to be increased to ensure that the cover 100a has sufficient mechanical strength. However, this will compress the size space of the display assembly 200 in the mobile phone 1a, ultimately resulting in low space utilization of the mobile phone 1a.

[0086] To address the technical problems of poor aesthetics and low space utilization in the aforementioned mobile phone 1a, this application also provides a mobile phone 1b. Mobile phone 1b includes a cover 100b, a display assembly 200, and a main body 300. The cover 100b includes a first portion 110b and a second portion 120b that are connected. The display assembly 200 is supported on the main body 300 and has a gap, which the cover 100b covers. The first portion 110b covers at least a portion of the edge of the display assembly 200. The second portion 120b extends toward the main body 300 and is mounted on the main body 300. The main body 300 includes a sound cavity 400, and the cover 100b and / or the main body 300 have a sound outlet channel 500b communicating with the sound cavity 400 and the outside of the mobile phone 1b. The area of ​​the sound outlet 501b of the sound outlet channel 500b projected onto the side projection plane is greater than 0. The side projection surface is perpendicular to the plane where the display assembly is located and parallel to the edge of the display assembly 200 corresponding to the sound output channel 500b. This will be discussed in conjunction with... Figure 7 Provide a detailed description.

[0087] Figure 7 In other embodiments of this application, mobile phone 1b is shown in... Figure 3 A magnified view of a portion of region S2.

[0088] like Figure 7As shown, in some embodiments of this application, the mobile phone 1b includes a cover 100b, a display assembly 200, and a body 300. The cover 100b includes a first portion 110b and a second portion 120b that are connected to each other. The display assembly 200 is supported on the body 300, and a gap (not shown) is formed between the display assembly 200 and the body 300. The first portion 110b of the cover 100b covers at least a portion of the edge of the display assembly 200, and the orthographic projection of the first portion 110b in a first projection plane at least partially coincides with the orthographic projection of the edge of the display assembly 200 in the first projection plane. The second portion 120b of the cover 100b extends from the first portion 110b toward the body 300 and is mounted on the body 300 through the gap. The body 300 includes a sound cavity 400, and a sound outlet channel 500b is formed on the cover 100b and / or the body 300. The sound outlet 500b connects the sound cavity 400 and the exterior of the mobile phone 1b. The area of ​​the sound outlet 501b of the sound outlet 500b projected onto the second projection plane is greater than 0. (Reference) Figure 7 It is understood that the sound outlet 501b of the sound outlet channel 500b is at least partially opened on the second cover surface 102b of the cover 100b, and the cover 100b at least partially forms the sound outlet 501b of the sound outlet channel 500b. The second cover surface 102b is the surface on the first portion 110b that faces away from the display screen assembly 200 and is not parallel to the first projection surface, which will not be described in detail below.

[0089] Figure 8 A partial enlarged view of the mobile phone 1b in region S1 of FIG2(a) is shown in some embodiments of this application.

[0090] Combination Figure 7 and Figure 8 As can be seen, since the sound outlet 500b is located on the cover 100b and / or the main body 300, and the sound outlet 501b of the sound outlet 500b is located on the second cover surface 102b of the cover 100b, when the user observes the mobile phone 1b from the side where the display assembly 200 is located, the sound outlet 501b of the sound outlet 500b cannot be directly observed, and therefore other internal components of the mobile phone 1 cannot be observed through the sound outlet 501b of the sound outlet 500b. The concept of the sound outlet 501b has been described above and will not be repeated here.

[0091] In the aforementioned mobile phone 1b, when a sound channel 500b is formed on the cover 100b, and the area of ​​the sound channel 500b projected onto the second projection plane is greater than 0, on the one hand, when the user observes the mobile phone 1b from the side where the display assembly 200 is located, the sound channel 500b and other internal components will not be visible, thus improving the aesthetics of the mobile phone 1b. On the other hand, it is not necessary to increase the size of the first portion 110b to ensure the mechanical performance of the cover 100b. Therefore, in the mobile phone 1b, the size space of the display assembly 200 can be increased, and the space utilization efficiency of the mobile phone 1b can be improved.

[0092] For ease of understanding, the area of ​​the orthographic projection of the sound outlet 501b of the sound outlet channel 500b in the first projection plane is defined as A1, and the area of ​​the orthographic projection of the sound outlet 501b of the sound outlet channel 500b in the second projection plane is defined as A2. The ratio of A1 to A2 is defined as the orthographic-lateral ratio parameter. It can be understood that the smaller the orthographic-lateral ratio parameter, the larger the orthographic projection of the sound outlet 501b of the sound outlet channel 500b in the second projection plane is compared to the orthographic projection of the sound outlet 501b of the sound outlet channel 500b in the first projection plane; conversely, the larger the orthographic-lateral ratio parameter, the smaller the orthographic projection of the sound outlet 501b of the sound outlet channel 500b in the second projection plane is compared to the orthographic projection of the sound outlet 501b of the sound outlet channel 500b in the first projection plane. This application does not impose specific limitations on the value of the orthographic-lateral ratio parameter.

[0093] In some embodiments of this application, the front-to-side ratio parameter may be less than or equal to 1. For example, the front-to-side ratio parameter may be at least one of 0, 0.05, 0.1, 0.15, 0.2, 0.25, 0.3, 0.35, 0.4, 0.45, 0.5, 0.55, 0.6, 0.65, 0.7, 0.75, 0.8, 0.85, 0.9, 0.95, and 1.0.

[0094] It is worth noting that this application does not specifically limit the form of the sound output channel 500b. Any sound output channel 500b that meets the above conditions is within the protection scope of this application.

[0095] It is understood that the sound output channel 500b in this application can extend in various ways. Among them, the extension direction of the sound output channel 500b can be the direction from the sound inlet 502b of the sound output channel 500b to the sound outlet 501b. Figures 9(a) to 9(d) Some embodiments are shown respectively. Figure 7Fig. 9(a) shows a partial enlarged view of the S3 region. In some implementations, the sound outlet channel 500b can be a straight channel extending along a straight line, as shown in Fig. 9(a). In alternative implementations, the sound outlet channel 500b can be a curved channel extending along a curve, as shown in Fig. 9(b). In alternative implementations, the sound outlet channel 500b can be a zigzag channel extending along a zigzag line, as shown in Figs. 9(c) and 9(d). The present application does not limit the sound outlet channel 500b in this regard. Figures 9(a) to 9(d) The present application does not limit the sound outlet channel 500b in this regard.

[0096] The present application does not limit the sound outlet channel 500b in this regard. Figures 9(a) to 9(d) The present application does not limit the sound outlet channel 500b in this regard.

[0097] The present application does not limit the sound outlet channel 500b in this regard.

[0098] In some embodiments of the present application, the sound outlet port 501b of the sound outlet channel 500b is formed on the cover 100b and the main body 300. That is, the sound outlet port 501b of the sound outlet channel 500b is formed by the cover 100b and the main body 300. This will be described in detail below with reference to the accompanying drawings.

[0099] Fig. 10(a) shows a side view of the mobile phone 1b in some embodiments of the present application. Figures 10(b) to 10(d)Some embodiments of the partial enlarged view of the S4 region in FIG. 10(a) are shown. In some implementations, as shown in FIG. 10(b), a first sound outlet notch is formed on the cover 100b, and the first sound outlet notch and the surface of the main body 300 jointly form a sound outlet 501b of a sound outlet channel 500b. In alternative implementations, as shown in FIG. 10(c), a second sound outlet notch is formed on the main body 300, and the second sound outlet notch and the surface of the cover 100b jointly form the sound outlet 501b of the sound outlet channel 500b. In alternative implementations, as shown in FIG. 10(d), a first sound outlet notch is formed on the cover 100b, and a second sound outlet notch is formed on the main body 300, and the first sound outlet notch and the second sound outlet notch jointly form the sound outlet 501b of the sound outlet channel 500b. It can be understood that Figures 10(a) to 10(d) The distribution of the sound outlet channel 500b on the cover 100b and the main body 300 is only shown, and does not constitute a specific limitation on the implementations of the present application.

[0100] The mobile phone 1b only needs to form the sound outlet 501b of the sound outlet channel 500b by forming a notch on the cover 100b and / or the main body 300, and the overall processing difficulty is low, the small size structure of the cover 100b and the main body 300 is avoided, and the structural strength of the cover 100b and the main body 300 is improved.

[0101] In some embodiments of the present application, the sound outlet 501b of the sound outlet channel 500b is formed on the cover 100b. That is, the sound outlet 501b of the sound outlet channel 500b is surrounded by the cover 100b. In some implementations, the sound outlet 501b of the sound outlet channel 500b is only formed on the second cover surface 102b. In alternative implementations, the sound outlet 501b of the sound outlet channel 500b is partially formed on the first cover surface 101b and partially formed on the second cover surface 102b. The present application does not make a specific limitation on this.

[0102] In some embodiments of the present application, the sound outlet 501b of the sound outlet channel 500b is formed on the main body 300. That is, the sound outlet 501b of the sound outlet channel 500b is surrounded by the main body 300.

[0103] In addition, in some implementations, the cross-sectional shape of the sound outlet channel 500b at different positions can be the same. In alternative implementations, the cross-sectional shape of the sound outlet channel 500b at different positions can be different. The present application does not make a specific limitation on this. It can be understood that in the present application, the cross section refers to a plane perpendicular to the extension direction of the sound outlet channel, and the cross-sectional shape refers to the shape obtained after the part is cut along the cross section.

[0104] In some implementations, the cross-sectional shape of the sound outlet passage 500b can be at least one of a regular shape such as a rectangle, a circle, a triangle, a pentagon, etc. In alternative implementations, the cross-sectional shape of the sound outlet passage 500b can also be an irregular shape. The present application does not make a specific limitation in this regard.

[0105] The technical solutions of the present application will be described in detail below with reference to the accompanying drawings.

[0106] Application scenario 1

[0107] In application scenario 1, the mobile phone is a folding electronic device capable of switching between an unfolded state and a folded state. When the mobile phone is in the unfolded state, all components in the mobile phone can be said to be in the unfolded state, and when the mobile phone is in the folded state, all components in the mobile phone can be said to be in the folded state. In addition, the mobile phone can also be in an intermediate state between the unfolded state and the folded state, wherein the intermediate state, which can also be referred to as a hovering state (or a rotating state), can be any state between the unfolded state and the folded state. It can be understood that the folding electronic device in the present application can be an inner folding device, i.e., the display assembly of the mobile phone in the folded state is located on the inner side of the main body, and the folding electronic device in the present application can also be an outer folding device, i.e., the display assembly of the mobile phone in the folded state is located on the outer side of the main body. The present application does not make a specific limitation in this regard. It is worth noting that for the folding electronic device in the present application, the direction determined according to the display assembly refers to the direction determined according to the display assembly of the folding electronic device in the unfolded state, or the direction determined according to the display assembly of the folding electronic device in the intermediate state, which will not be described below. For example, the first projection surface and the second projection surface of the folding electronic device.

[0108] Figure 11 An exploded view of the mobile phone 1 in some embodiments of the present application is shown, wherein the mobile phone 1 is a folding electronic device and the drawing is in a first perspective view. As shown in Figure 11 In some embodiments of the present application, the mobile phone 1 includes a cover 100, a cover 100', a display assembly 200, a main body 300, a main body 300', and a rotating shaft mechanism 300". The rotating shaft mechanism 300" is rotatably connected between the main body 300 and the main body 300'.

[0109] The display screen assembly 200 comprises a flexible screen 210 and a screen supporting plate 220. The flexible screen 210 can comprise a first sub-zone 211, a second sub-zone 212 and a third sub-zone 213. The screen supporting plate 220 can comprise a first supporting part 221, a second supporting part 222 and a third supporting part 223. The first sub-zone 211 is arranged opposite to the first supporting part 221 and fixed to each other. The second sub-zone 212 is arranged opposite to the second supporting part 222 and fixed to each other. The third sub-zone 213 is arranged opposite to the third supporting part 223. The flexible screen 210 can be a flexible organic light-emitting diode (OLED), which is not limited in the present application.

[0110] In the unfolded state, the first sub-zone 211, the third sub-zone 213 and the second sub-zone 212 are arranged in sequence along the x-axis direction. The first supporting part 221, the third supporting part 223 and the second supporting part 222 are arranged in sequence along the x-axis direction. The main body 300, the pivot mechanism 300” and the main body 300’ are arranged in sequence along the x-axis direction. In the folded state, the support plates (also referred to as door plates) in the pivot mechanism 300” jointly enclose a specific shape (for example, a water drop shape). The third supporting part 223 encloses a space with a specific shape. The third sub-zone 213 is bent into a specific shape (for example, a water drop shape) that is adapted to the space, and is accommodated in the space with the specific shape. The first sub-zone 211 and the second sub-zone 212 are arranged face to face. In the folded state, the main body 300, the first supporting part 221 and the first sub-zone 211 are arranged in layers in the thickness direction of the mobile phone 1. The second sub-zone 212, the second supporting part 222 and the main body 300’ are arranged in layers.

[0111] The first sub-zone 211 and the main body 300 form a first gap (not shown) therebetween. The cover 100 is arranged on the first sub-zone 211 and the main body 300 to shield the first gap therebetween, and the cover 100 is connected to the main body 300. The second sub-zone 212 and the main body 300’ form a second gap (not shown) therebetween. The cover 100’ is arranged on the second sub-zone 212 and the main body 300’ to shield the second gap therebetween, and the cover 100’ is connected to the main body 300’.

[0112] It can be understood that when the mobile phone 1 is a folding electronic device, the first gap can be a gap formed by the relative sliding of the first sub-area 211 (i.e., the display screen assembly 200) and the main body 300 when the mobile phone 1 switches between the folded state and the flattened state. The first gap can also be a gap formed between the first sub-area 211 (i.e., the display screen assembly 200) and the main body 300 due to design, molding, assembly, etc. in the mobile phone 1. Similarly, the second gap can be a gap formed by the relative sliding of the second sub-area 212 (i.e., the display screen assembly 200) and the main body 300' when the mobile phone 1 switches between the folded state and the flattened state. The second gap can also be a gap formed between the second sub-area 212 (i.e., the display screen assembly 200) and the main body 300' due to design, molding, assembly, etc. in the mobile phone 1.

[0113] It can be understood that the above implementation manner is only a partial example of the mobile phone 1, and other forms of the mobile phone 1 are also within the protection scope of the present application. For example, the mobile phone 1 is a folding electronic device, and the display screen of the electronic device is two, which are respectively located on the opposite sides of the main body, one of which covers the two main bodies and the hinge mechanism, and the other of which covers one of the main bodies and the hinge mechanism. In summary, any electronic device that covers the gap between the main body and the display screen assembly by the cover can be the mobile phone 1 in the present application, which is not specifically limited in the present application.

[0114] In some embodiments of the present application, the cover 100 has the same structure or similar structure as the cover 100b in the foregoing embodiments. That is, the sound outlet channel in the mobile phone 1 can be formed on the cover 100. In some other embodiments of the present application, the cover 100' also has the same structure or similar structure as the cover 100b in the foregoing embodiments, that is, the sound outlet channel in the mobile phone 1 can also be formed on the cover 100'. In some other embodiments of the present application, the cover 100 and the cover 100' both have the same structure or similar structure as the cover 100b in the foregoing embodiments, that is, the sound outlet channel in the mobile phone 1 can be formed on the cover 100 and the cover 100'. For example, the sound outlet channel 500 can include multiple sound outlet channels, and the sound outlet of at least one sound outlet channel 500 is formed on the cover 100, and the sound outlet of at least one sound outlet channel 500 is formed on the cover 100'. For another example, the number of sound outlet channels 500 is one, and the sound outlet of the sound outlet channel 500 is partially formed on the cover 100 and partially formed on the cover 100'. The present application does not specifically limit this.

[0115] The specific structure of the present application will be described in detail below taking the example that the sound outlet channel is formed on the cover 100, that is, the sound outlet of the sound outlet channel is at least partially formed on the cover 100.

[0116] Figure 12 A top view of the mobile phone 1 in some embodiments of the present application is shown. As shown in FIG. 1, the mobile phone 1 includes a main body 300, a cover 100, a hinge mechanism 400, a first sub-area 211, and a second sub-area 212. Figure 12As shown, in some embodiments of the present application, the cover 100 can be divided into a first section I, a second section II and a third section III. The second section II and the third section III are parallel and oppositely arranged, and the second section II and the third section III are respectively connected with two ends of the first section I. The sound outlet channel 500 can be arranged at any position on the first section I, the second section II and the third section III.

[0117] With reference to the foregoing Figure 12 In some implementations, the sound outlet channel 500 can be arranged at a middle position of the first section I of the cover 100. For example, the sound outlet channel 500 is arranged on the cover 100 in the S5 region of the first section I. Figure 12

[0118] With reference to the foregoing Figure 12 In some implementations, the region where the sound outlet channel 500 is arranged on the cover 100 can be different from the region of the cover 100 connected with the main body 300. For example, the sound outlet channel 500 is arranged on the cover 100 in the first section I, and the region of the cover 100 connected with the main body 300 is located in the second section II. In alternative implementations, the region where the sound outlet channel 500 is arranged on the cover 100 can be the same as the region of the cover 100 connected with the main body 300. For example, the sound outlet channel 500 is arranged on the cover 100 in the first section I, the region of the cover 100 connected with the main body 300 is located in the first section I, and the region where the sound outlet channel 500 is arranged on the cover 100 is opposite to the region of the cover 100 connected with the main body 300. It can be understood that, in the present application, the two regions are different means that the orthographic projection of the two regions in the first projection plane does not coincide. In the present application, the two regions are the same means that the orthographic projection of the two regions in the first projection plane substantially coincides.

[0119] In order to balance the structure of the cover 100 and improve the overall strength of the cover 100, in some embodiments of the present application, the region where the sound outlet channel 500 is arranged on the cover 100 is the same as the region of the cover 100 connected with the main body 300.

[0120] Figure 13 A sectional view of the mobile phone 1 along the N-N section plane in some embodiments of the present application is shown, wherein the N-N section plane passes through the sound outlet channel 500 in the mobile phone 1. Figure 12 A sectional view of the mobile phone 1 along the N-N section plane in some embodiments of the present application is shown, wherein the N-N section plane passes through the sound outlet channel 500 in the mobile phone 1. Figure 14 A partial enlarged view of the S6 region in some embodiments of the present application is shown. Figure 13 A partial enlarged view of the S7 region in some embodiments of the present application is shown. Figure 15 A partial enlarged view of the S7 region in some embodiments of the present application is shown. Figure 14 A partial enlarged view of the S7 region in some embodiments of the present application is shown.

[0121] For the convenience of description and understanding, the technical solutions in the present application will be described below in combination with the cover 100, the display screen assembly 200 and the main body 300. The description will be combined with​Figures 13 to 15 It can be seen that the main body 300 comprises a support surface 301. The display screen assembly 200 is supported on the support surface 301, and a first gap (not labeled) is formed between the display screen assembly 200 and the main body 300. The cover 100 covers the display screen assembly 200 and the main body 300 to shield the first gap. The cover 100 and / or the main body 300 is provided with a sound outlet channel 500, and a sound outlet 501 of the sound outlet channel 500 faces the periphery of the mobile phone 1, and a sound inlet 502 of the sound outlet channel 500 communicates with the sound cavity 400. The periphery of the mobile phone 1 refers to the upper side, the lower side, the left side and the right side of the mobile phone 1 when a user observes the mobile phone 1 from the side where the display screen assembly 200 is located.

[0122] In some embodiments of the present application, the sound inlet 502 of the sound outlet channel 500 communicates with the sound cavity 400 when the mobile phone 1 is in the unfolded state and the intermediate state. It can be understood that when the mobile phone 1 is switched from the folded state to the unfolded state, or when the mobile phone 1 is switched from the unfolded state to the folded state, the edge of the display screen assembly 200 parallel to the shaft mechanism 302 slides relative to the corresponding cover 100 in the first direction F1. Compared with the unfolded state, the edge of the display screen assembly 200 parallel to the shaft mechanism 302 slides towards the corresponding cover 100 in the intermediate state and the folded state. In order to ensure the normal use of the sound outlet channel 500 in the intermediate state and the unfolded state, it is necessary to ensure that the sound inlet 502 of the sound outlet channel 500 communicates with the sound cavity 400 in these two states.

[0123] In some implementations, the sound inlet 502 of the sound outlet channel 500 is provided on the surface of the second part 120 facing the edge of the display screen assembly 200 (for example, the first side plate surface 1211 in FIG. 16(a) below).

[0124] In some implementations, the sound inlet 502 of the sound outlet channel 500 is provided on the surface of the second part 120 facing the edge of the display screen assembly 200 (for example, the first side plate surface 1211 in FIG. 16(a) below), and the orthographic projection of the sound inlet 502 in the second projection plane at least partially does not coincide with the orthographic projection of the display screen assembly 200 in the second projection plane.

[0125] The above mobile phone 1 can realize that the sound inlet 502 of the sound outlet channel 500 communicates with the sound cavity 400 in the unfolded state and the intermediate state by reasonably setting the position of the sound inlet 502 on the sound outlet channel 500. That is, the normal work of the loudspeaker module 350 in the mobile phone 1 can be realized.

[0126] Continuing to refer to Figure 14 and Figure 15In some embodiments of the present application, the cover 100 comprises a first part 110 and a second part 120. The first part 110 covers the display screen assembly 200 and the main body 300 to shield a first gap between the display screen assembly 200 and the main body 300. The second part 120 extends from the first part 110 in a direction pointing to the main body 300 (e.g. the F0 direction in Figure 15 FIG. 1), and one side of the second part 120 is connected to the first part 110, and the other side of the second part 120 is installed on the main body 300 through the first gap between the display screen assembly 200 and the main body 300.

[0127] Continuing to refer to Figure 14 and Figure 15 In some embodiments of the present application, the main body 300 comprises a middle frame 310 and a fixed block 320. The first gap between the display screen assembly 200 and the main body 300 can be a gap between the display screen assembly 200 and the middle frame 310. In the first direction, the display screen assembly 200 and the middle frame 310 are respectively arranged on the opposite sides of the second part 120. The first direction is a direction pointing from the middle frame 310 to the fixed block 320 (e.g. the F1 direction in Figure 15 FIG. 1), for example, the first direction is parallel to the x-axis. The second part 120 is installed on the middle frame 310 and / or the fixed block 320. It can be understood that when the installation position of the sound outlet channel 500 on the cover 100 changes, the first direction can be adaptively adjusted according to the relative position of the sound outlet channel 500 relative to the cover 100. For example, when the sound outlet channel 500 is arranged on the second section II or the third section III of the cover 100, the first direction is parallel to the y-axis. The present application does not make specific limitations in this regard.

[0128] Continuing to refer to Figure 14 and Figure 15 In some embodiments of the present application, the display screen assembly 200 has a first surface 201 and a second surface 202 arranged oppositely. The main body 300 has a support surface 301. The support surface 301 can be a certain plane in the main body 300, or the support surface 301 can also be a plane formed by multiple structures in the main body 300. The present application does not make specific limitations in this regard. The first surface 201 of the display screen assembly 200 is attached to the support surface 301 of the main body 300, so that the display screen assembly 200 is supported on the main body 300.

[0129] In some implementations, the first surface 201 is a backlight surface of the display screen assembly 200, and the second surface 202 is a light outlet surface of the display screen assembly 200. In alternative implementations, the first surface 201 is a light outlet surface of the display screen assembly 200, and the second surface 202 is a backlight surface of the display screen assembly 200.

[0130] As Figure 14As shown, in some embodiments of this application, the main body 300 further includes a support member 330. The support member 330 is connected to the middle frame 310 and the fixing block 320. A support surface is formed on the support member 330, which is the support surface 301 of the main body 300. The first surface 201 of the display assembly 200 is in contact with the support surface of the support member 330.

[0131] like Figure 14 As shown, in some embodiments of this application, the main body 300 further includes a rear shell 340 and a speaker module 350. The middle frame 310, fixing block 320, support member 330, and rear shell 340 are connected. The middle frame 310, fixing block 320, support member 330, and rear shell 340 together form a mounting cavity (not shown), and the speaker module 350 is located within the mounting cavity.

[0132] In some embodiments of this application, a sound-producing cavity is formed inside the speaker module 350. The sound-producing cavity is connected to the mounting cavity to expand the volume of the sound-producing cavity. The sound-producing cavity and the mounting cavity outside the speaker module 350 can serve as the sound cavity 400 in this application. The speaker module 350 is a sound-to-electrical conversion device. The operating state of the speaker module 350 can be the state corresponding to application scenarios such as playing music, video, or making calls on a mobile phone. In some implementations, the speaker module 350 can be a receiver or a speaker, which is not specifically limited in this application.

[0133] like Figure 15 As shown, the cover 100, the display assembly 200, and the main body 300 together form the sound cavity 400 (e.g., Figure 15 The dark gray area in the middle), the cover 100 and the main body 300 together form the sound output channel 500 (such as the ... Figure 15 (The light gray area in the image). The sound output channel 500 includes a first sub-sound output channel 510, a second sub-sound output channel 520, and a third sub-sound output channel 530. The first sub-sound output channel 510 is connected to the sound cavity 400 and the second sub-sound output channel 520, respectively. The third sub-sound output channel 530 is connected to the second sub-sound output channel 520 and the outside of the mobile phone 1, respectively.

[0134] The technical solution in this application will be further described below in conjunction with the specific structure of the cover 100.

[0135] Figure 16(a) illustrates some embodiments of this application. Figure 14 A partially enlarged view of the cover 100 in region S7, with the cover 100 in a first-view perspective. Figure 16(b) illustrates some embodiments of this application. Figure 14 A magnified view of a portion of the cover 100 in region S7, with the cover 100 shown from a second-person perspective. Combined with... Figure 15As shown in FIG. 16(a) and FIG. 16(b), in some embodiments of the present application, the cover 100 comprises a first part 110 and a second part 120. The first part 110 comprises a first cover surface 101, a second cover surface 102, and a third cover surface 103. The first cover surface 101 and the second cover surface 102 of the first part 110 face away from the second surface 202 of the display screen assembly 200, and the third cover surface 103 of the first part 110 faces the second surface 202 of the display screen assembly 200. The first cover surface 101 and the second cover surface 102 are connected, and the first cover surface 101 and the third cover surface 103 are oppositely arranged.

[0136] In some implementations, the third cover surface 103 is in contact with the second surface 202. In alternative implementations, the third cover surface 103 is spaced apart from the second surface 202. It can be understood that, when the third cover surface 103 is spaced apart from the second surface 202, the third cover surface 103 can be parallel or approximately parallel to the second surface 202, which is not limited in the present application. In this case, the first part 110 and the display screen assembly 200 are spaced apart in the thickness direction to form a gap.

[0137] Figure 17 FIG. 16(a) and FIG. 16(b) show the structure of the cover 100 in some embodiments of the present application. Figure 14 FIG. 16(c) is a partial enlarged view of the S7 region in FIG. 16(b), in which the cross section of the first sub-sound passage 510 is marked. In combination with FIG. 16(a), FIG. 16(b), and FIG. 16(c), it can be known that, in some embodiments of the present application, the second part 120 comprises a first side plate 121, and the first side plate 121 is provided with a through hole 130, which constitutes the first sub-sound passage 510. Figure 17

[0138] The above mobile phone 1, the sound inlet of the first sub-sound passage 510 is in communication with the sound cavity, and the first sub-sound passage 510 is arranged on the first side plate 121 in the second part 120. That is, the sound inlet of the first sub-sound passage 510 is arranged on the surface of the first side plate 121, so as to ensure that the sound inlet of the first sub-sound passage 510 is in communication with the sound cavity when the mobile phone 1 is switched between the folded state, the flat state, and the intermediate state, thereby ensuring that the loudspeaker module 350 can work normally in each state.

[0139] In some implementations, the first side plate 121 comprises a first side plate surface 1211 and a second side plate surface 1212 oppositely arranged. The first side plate surface 1211 faces the middle frame 310, the second side plate surface 1212 faces away from the middle frame 310 and faces the edge of the display screen assembly 200, and the through hole 130 is in communication with the first side plate surface 1211 and the second side plate surface 1212. ​

[0140] In some other embodiments of the present application, the second part 120 comprises a first side plate 121, the first side plate 121 is provided with a U-shaped through slot on one end thereof which faces away from the first part 110, and the slot wall of the U-shaped through slot and the surface of the main body 300 form a first sub-sound outlet channel 510. In some implementations, the first side plate 121 comprises a first side plate surface and a second side plate surface which are oppositely arranged. Among them, the first side plate surface faces the middle frame 310, the second side plate surface faces away from the middle frame 310 and faces the edge of the display screen assembly 200, and the U-shaped through slot communicates the first side plate surface and the second side plate surface.

[0141] In some application scenarios, the cross-sectional size of the first sub-sound outlet channel 510 is large, in order to maintain the mechanical properties of the cover 100, in some embodiments of the present application, a reinforcing part is arranged in the first sub-sound outlet channel 510 to enhance the mechanical properties of the cover 100. Continue to refer to FIG. 16(a), FIG. 16(b) and Figure 17 , the second part 120 in the cover 100 also comprises a reinforcing part 122. Among them, the reinforcing part 122 is distributed in the first sub-sound outlet channel 510 (that is, the through hole 130) and respectively interfaces with the surfaces opposite to the first sub-sound outlet channel 510.

[0142] For example, the first sub-sound outlet channel 510 is a rectangular channel, and the reinforcing part 122 is a rectangular block. Among them, the rectangular channel comprises a first channel surface and a second channel surface which are oppositely arranged. The rectangular block comprises a first rectangular surface and a second rectangular surface which are oppositely arranged. The first channel surface interfaces with the first rectangular surface, and the second channel surface interfaces with the second rectangular surface.

[0143] It can be understood that the above is only one of the implementations of the first sub-sound outlet channel 510 in the present application, and other forms of the first sub-sound outlet channel 510 which can realize the sound outlet function are also within the protection scope of the present application, and the present application does not make specific limitation thereon. For example, the cross-sectional shape of the first sub-sound outlet channel 510 can be circular, elliptical, square and the like. Similarly, the above is only one of the implementations of the reinforcing part 122 in the present application, and other forms of the reinforcing part 122 which can realize the reinforcing function are also within the protection scope of the present application, and the present application does not make specific limitation thereon. For example, the cross-sectional shape of the reinforcing part 122 can be circular, elliptical, square and the like.

[0144] Figure 18 The partial enlarged view of the main body 300 in the S7 region of some embodiments of the present application is shown. Figure 14 The partial enlarged view of the main body 300 in the S7 region of some embodiments of the present application is shown. Figure 19 The partial enlarged view of the main body 300 in the S7 region of some embodiments of the present application is shown. Figure 14 The partial enlarged view of the main body 300 in the S7 region of some embodiments of the present application is shown. Figure 18 and Figure 19It can be seen that, in some embodiments of the present application, the second sub-sound outlet channel 520 is formed between the main body 300 and the second part 120 in the mobile phone 1. In some implementations, the second sub-sound outlet channel 520 is formed between the middle frame 310 in the main body 300 and the second part 120.

[0145] In some embodiments of the present application, the second sub-sound outlet channel 520 is in communication with the first sub-sound outlet channel 510 and the third sub-sound outlet channel 530, respectively, and the first sub-sound outlet channel 510 is in communication with the sound cavity 400, and the third sub-sound outlet channel 530 is in communication with the outside of the mobile phone 1.

[0146] In some implementations, the sound inlet of the first sub-sound outlet channel 510 is in communication with the sound cavity 400, the sound outlet of the first sub-sound outlet channel 510 is in communication with the sound inlet of the second sub-sound outlet channel 520, and the sound outlet of the second sub-sound outlet channel 520 is in communication with the sound inlet of the third sub-sound outlet channel 530.

[0147] In some embodiments of the present application, the projection of the sound outlet of the second sub-sound outlet channel 520 on the first sub-sound outlet channel 510 is located in the channel surface of the first sub-sound outlet channel 510 and / or the channel surface of the second sub-sound outlet channel 520. That is, any straight line outside the mobile phone 1 cannot pass through the second sub-sound outlet channel 520 and the first sub-sound outlet channel 510 to reach the inside of the sound cavity 400.

[0148] When a user observes the inside of the mobile phone 1 through the second sub-sound outlet channel 520, only the channel surface of the first sub-sound outlet channel 510 and / or the channel surface of the second sub-sound outlet channel 520 can be observed, and the structure inside the mobile phone 1 cannot be observed. That is, when observed from the outside to the inside of the mobile phone 1, the internal structure of the mobile phone 1 cannot be seen at any angle, further improving the appearance of the mobile phone 1.

[0149] In combination Figure 18 and Figure 19 It can be seen that the main body 300 includes the middle frame 310 and the fixing block 320. In the first direction, the middle frame 310 and the fixing block 320 are separately arranged on opposite sides of the second part 120. The middle frame 310 and the fixing block 320 are relatively fixed. The second part 120 is mounted on the middle frame 310 and / or the fixing block 320.

[0150] It can be understood that the middle frame 310 in the present application is not only used to fix the second part 120. In some other embodiments of the present application, the middle frame 310 can also be integrally formed with other structures in the main body 300, such as a mounting rack for mounting the loudspeaker module 350 and the like. Similarly, the fixing block 320 in the present application is not only used to fix the second part 120. In some other embodiments, the fixing block 320 can also be integrally formed with other structures in the main body 300. No specific limitation is made in this regard.

[0151] The mobile phone 1 sets the main body 300 for installing the second part 120 of the cover 100 as two components of the middle frame 310 and the fixing block 320, thereby reducing the assembly difficulty of the second part 120 on the main body 300.

[0152] In combination Figure 18 And Figure 19 It can be known that, in some embodiments of the present application, the middle frame 310 and the fixing block 320 are connected, and the mounting groove 360 is formed at the connecting surface of the middle frame 310 and the fixing block 320. The second part 120 of the cover 100 is installed in the mounting groove 360, and the second part 120 is connected with the groove surface of the mounting groove 360. That is, the second part 120 of the cover 100 is installed on the middle frame 310 and / or the fixing block 320.

[0153] In some implementations, the second part 120 of the cover 100 is bonded to the groove surface of the mounting groove 360. It can be understood that the above implementation is only one of the connection modes of the second part 120 and the mounting groove 360, and other connection modes capable of installing the second part 120 in the mounting groove 360 are also within the protection scope of the present application, such as clamping, welding, etc., which are not limited in the present application.

[0154] In some other embodiments of the present application, the main body 300 is a one-piece structure, and the mounting groove 360 is formed on the one-piece structure, and the second part 120 of the cover 100 is installed in the mounting groove 360.

[0155] In combination Figure 18 And Figure 19 It can be known that, in some embodiments of the present application, the middle frame 310 includes the second side plate 311. In the first direction F1, the second side plate 311, the first side plate 121 and the display screen assembly 200 are sequentially arranged. The first side plate 121 and the second side plate 311 form the first sound outlet gap therebetween, and the first sound outlet gap constitutes the second sub-sound outlet channel 520. Moreover, along the first direction F1, the second side plate 311 blocks the sound outlet of the first sub-sound outlet channel 510.

[0156] It can be understood that, in the present application, one component blocks another component means that the normal projection of one component on a plane covers the normal projection of another component on the plane. For example, the second side plate 311 blocks the sound outlet of the first sub-sound outlet channel 510, which can mean that the normal projection of the second side plate 311 on a plane covers the normal projection of the sound outlet of the first sub-sound outlet channel 510 on the plane.

[0157] The mobile phone 1 can shield the sound outlet of the first sub sound outlet channel 510 by arranging the second side plate 311 in the middle frame 310, so as to avoid the user from observing the sound outlet of the first sub sound outlet channel 510 when the user is in other directions, for example, the user cannot observe the sound outlet of the first sub sound outlet channel 510 when the user observes the mobile phone 1 along the first direction. Therefore, the user cannot observe the internal structure of the mobile phone 1 through the sound outlet 501 of the sound outlet channel 500.

[0158] In combination Figure 18 and Figure 19 It can be known that, in some embodiments of the present application, the third side plate surface 3111 of the second side plate 311 in the middle frame 310 is in contact with the first fixing surface 321 in the fixing block 320.

[0159] In some embodiments of the present application, the groove surface of the mounting groove 360 can include Figure 18 the fourth side plate surface 3112 of the second side plate 311 in the middle frame 310, and can also include Figure 18 the second fixing surface 322 of the fixing block 320.

[0160] Continuing to refer to Figure 18 and Figure 19 In some embodiments of the present application, the surface of the second side plate 311 opposite to the first side plate 121 is provided with the first notch 370, and the first notch 370 is aligned with the second sub sound outlet channel 520 along the first direction F1.

[0161] Continuing to refer to Figure 18 and Figure 19 In some implementations, the second side plate 311 includes the fourth side plate surface 3112, and the fourth side plate surface 3112 is opposite to the first side plate 121. The fourth side plate surface 3112 is the surface of the second side plate 311 opposite to the first side plate 121. The fourth side plate surface 3112 is provided with the first notch 370.

[0162] The mobile phone 1 is provided with the first notch 370 on the second side plate 311, which expands the size of the second sub sound outlet channel 520 under the premise of slightly increasing the processing difficulty and assembly difficulty, so as to facilitate the optimization of the sound effect of the mobile phone 1.

[0163] In order to improve the stability of the relative position relationship between the cover 100 and the main body 300, in some embodiments of the present application, the main body 300 is further provided with a positioning block 380. For example, in combination with FIG. 16(a) and Figure 18As shown, the fixing block 320 in the main body 300 is provided with a positioning block 380. The second part 120 in the cover 100 is formed with a positioning groove 150 matched with the positioning block 380, and in the assembled state, the positioning block 380 in the main body 300 is located in the positioning groove 150 in the cover 100. In some other embodiments of the present application, the main body 300 is also formed with a positioning groove. The second part 120 in the cover 100 is provided with a positioning block matched with the positioning groove, and in the assembled state, the positioning block in the cover 100 is located in the positioning groove in the main body 300.

[0164] The mobile phone 1 described above, by setting the positioning block and the positioning groove between the main body 300 and the cover 100, facilitates the accurate positioning of the main body 300 and the cover 100, reduces the assembly difficulty of the mobile phone 1, and at the same time can improve the stability of the relative position of the main body 300 and the cover 100 in the mobile phone 1.

[0165] Figure 20 As shown in FIG. 16(a) and FIG. 16(b), the mobile phone 1 in some embodiments of the present application is provided with a display screen assembly 200 and a main body 300. Figure 14 FIG. 17 is a partial enlarged view of the S7 region in FIG. 16(a), in which the cross section of the third sub sound outlet channel 530 is marked. As shown in FIG. 17, the third sub sound outlet channel 530 is formed between the first part 110 and the second side plate 311 in the cover 100. Figure 20 As shown, in some embodiments of the present application, in the second direction F2, the first part 110 of the cover 100 blocks the sound outlet of the second sub sound outlet channel 520. The second direction F2 is perpendicular to the first projection plane. And the second sound outlet gap is formed between the first part 110 and the second side plate 311, and the second sound outlet gap constitutes the third sub sound outlet channel 530. In some implementations, in combination with Figure 15 and Figure 20 It can be seen that the direction F0 is parallel to the second direction F2.

[0166] The mobile phone 1 described above, by blocking the sound outlet of the second sub sound outlet channel 520 by the first part 110, avoids the user from observing the first sub sound outlet channel 510 and the second sub sound outlet channel 520 from the outside, and further beautifies the appearance of the mobile phone 1.

[0167] In order to realize the cover 100 to hide the gap between the display screen assembly 200 and the main body 300, in combination with Figure 14 , Figure 15 and Figure 20 It can be seen that in some embodiments of the present application, a part of the first part 110 covers at least part of the display screen assembly 200, and another part extends through the first gap between the display screen assembly 200 and the main body 300 and covers the middle frame 310 in the main body 300.

[0168] Continuing to refer to FIG. 16(a) and FIG. 16(b), Figure 20In some embodiments of the present application, the surface of the first part 110 opposite to the second side plate 311 is provided with a second notch 140, and the second notch 140 is aligned with the second sub-sound outlet channel 520 along the second direction F2. The second notch 140 and the second sound outlet gap jointly constitute a third sub-sound outlet channel 530.

[0169] The mobile phone 1 described above, by providing the first part 110 with the second notch 140, expands the size of the third sub-sound outlet channel 530, expands the communication path between the sound cavity 400 and the outside of the mobile phone 1, and facilitates the optimization of the sound effect of the mobile phone 1.

[0170] Referring to FIGS. 16(a), 16(b), Figure 18 and Figure 20 In some implementations, the first part 110 includes a fourth cover surface 104, and the second side plate 311 in the middle frame 310 includes a fifth side plate surface 3113, and the fourth cover surface 104 is in contact with the fifth side plate surface 3113 in the assembled state. The fourth cover surface 104 is the surface of the first part 110 opposite to the second side plate 311. The fourth cover surface 104 is provided with the second notch 140.

[0171] In order to optimize the sound effect of the mobile phone 1, the channel between the sound cavity 400 and the outside of the mobile phone 1 can be designed to be streamlined. Referring to Figure 15 In some embodiments of the present application, the components (such as the cover 100 and the main body 300) of the mobile phone 1 that constitute the channel between the sound cavity 400 and the outside of the mobile phone 1 are provided with an inclined angle and a rounded corner. This will not be described in detail here. For example, the position where the first part 110 and the second part 120 of the cover 100 meet is designed as a rounded corner structure. For another example, at the second notch 140 on the first part 110, the surface of the second notch 140 is slightly upward from inside to outside, so as to improve the sound effect of the mobile phone 1.

[0172] In order to reduce the difficulty of forming and assembling the components in the mobile phone 1, in some embodiments of the present application, the components (such as the cover 100 and the main body 300) of the mobile phone 1 that constitute the channel between the sound cavity 400 and the outside of the mobile phone 1 are provided with an inclined angle. This will not be described in detail here. For example, at the second notch 140 on the first part 110, the surface of the second notch 140 is slightly upward from inside to outside, so as to reduce the difficulty of stripping the cover 100.

[0173] In addition, in some other embodiments of the present application, the sound outlet channel 500 comprises a first sub-sound outlet channel 510 and a second sub-sound outlet channel 520. The first sub-sound outlet channel 510 in the present embodiment can be specifically referred to the first sub-sound outlet channel 510 in the foregoing embodiments, and the second sub-sound outlet channel 520 in the present embodiment can be specifically referred to the second sub-sound outlet channel 520 in the foregoing embodiments. However, it is worth noting that the difference between the present embodiment and the foregoing embodiments is that the sound outlet of the second sub-sound outlet channel 520 in the present embodiment directly communicates with the outside of the mobile phone 1.

[0174] In addition, the present application also provides a cover 100. The cover 100 comprises a first part 110 and a second part 120. The first part 110 is used to cover at least part of the edge of the display screen assembly 200, wherein the plane where the display screen assembly 200 is located is the first projection plane. The second part 120 is located on the side of the first part 110 facing the display screen assembly 200 and is connected with the first part 110. The second part 120 is used to be connected with the main body 300. The cover 100 is provided with at least part of the sound outlet channel 500, which is used to communicate the sound cavity 400 on the main body 300 with the outside of the mobile phone 1. The orthographic projection of the sound outlet channel 500 in the second projection plane is greater than 0. The second projection plane is perpendicular to the first projection plane and parallel to the edge of the display screen assembly 200 corresponding to the sound outlet channel 500.

[0176] In application scenario 2, the mobile phone is a non-foldable electronic device. The present application also provides a mobile phone suitable for application scenario 2. Figure 21 An exploded view of the mobile phone 1 in some embodiments of the present application is shown. By comparison Figure 21 And Figure 11It can be known that compared with the mobile phone in application scenario 1, the basic components of the mobile phone in application scenario 1 have changed: the mobile phone 1 comprises a cover 100, a display screen assembly 200 and a main body 300. However, the structures of the cover 100, the display screen assembly 200 and the main body 300 and the connection relationship therebetween are the same as those of the mobile phone 1 in application scenario 1. That is, the cover 100 comprises a first part and a second part. The display screen assembly 200 is supported on the main body 300. The plane where the display screen assembly 200 is located is a first projection plane. The first part of the cover 100 covers at least part of the display screen assembly 200, and the orthographic projection of the first part in the first projection plane at least partially coincides with the orthographic projection of the edge of the display screen assembly 200 in the first projection plane.

An acoustic outlet channel is formed in the cover 100, and the acoustic outlet channel communicates the acoustic cavity and the outside of the mobile phone 1, and the orthographic projection of the acoustic outlet channel in a second projection plane is greater than 0. The second projection plane is perpendicular to the first projection plane and parallel to the edge of the display screen assembly 200 corresponding to the acoustic outlet channel.

[0177] It can be understood that other features of the mobile phone 1 in application scenario 2 can refer to the cover 100, the display screen assembly 200 and the main body 300 of the mobile phone 1 in application scenario 1. Here, no further description will be given.

[0178] The present application also provides a cover 100 suitable for application scenario 2. The cover 100 comprises a first part and a second part. The first part is used to cover at least part of the edge of the display screen assembly 200, wherein the plane where the display screen assembly 200 is located is a first projection plane.
