[0041] Embodiments of the present disclosure are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present disclosure, but should not be understood as limiting the present disclosure.

[0042] like Figures 1 to 4 As shown, the audio module 10 of the embodiment of the present disclosure includes a bracket 1, an earpiece 2 and a loudspeaker 3. The bracket 1 is provided with a first sound cavity 11 and a second sound cavity 12. The earpiece 2 is provided in the first sound cavity 11, and the loudspeaker 3 is provided in the second sound cavity 12. The earpiece 2 and the loudspeaker 3 are both connected to the bracket 1. The first sound cavity 11 is provided on one side of the second sound cavity 12 in the first direction, and the orthographic projection of a part of the first sound cavity 11 in the second direction overlaps with the orthographic projection of a part of the second sound cavity 12 in the second direction. The second direction is perpendicular to the first direction.

[0043] The audio module 10 of the embodiment of the present disclosure connects both the earpiece 2 and the speaker 3 to the bracket 1, so that the bracket 1 serves not only as a mounting carrier for the earpiece 2 but also as a mounting carrier for the speaker 3, thereby reducing the number of mounting carriers, thereby reducing the assembly complexity of the audio module 10 and reducing the occupied space of the audio module 10. In addition, the first sound cavity 11 is arranged on one side of the second sound cavity 12 in the first direction (the X direction in the figure), and the orthographic projection of a part of the first sound cavity 11 in the second direction (the Y direction in the figure) overlaps with the orthographic projection of a part of the second sound cavity 12 in the second direction, so that the layout between the first sound cavity 11 and the second sound cavity 12 is compact, further reducing the occupied space of the audio module 10.

[0044] Alternatively, if Figure 2 As shown, the bracket 1 includes a partition 15, and the first sound cavity 11 and the second sound cavity 12 are separated by the partition 15. The thickness of the partition 15 in the first direction is 1 mm to 3 mm.

[0045] It is understandable that the greater the thickness of the partition 15, the better the structural strength of the bracket 1, but the larger the volume of the bracket 1; the smaller the thickness of the partition 15, the smaller the volume of the bracket 1, but the worse the structural strength of the bracket 1.

[0046] By setting the thickness of the partition 15 to 1 mm to 3 mm, the volume of the bracket 1 can be reduced while ensuring the structural strength of the bracket 1, thereby further reducing the space occupied by the audio module 10.

[0047] Optionally, the partition 15 is a partition.

[0048] In some embodiments, Figure 3 As shown, the bracket 1 includes a frame body 101 and a cover plate 102. The frame body 101 is provided with a first installation opening 1011 and a second installation opening 1012. The first installation opening 1011 is for the receiver 2 to pass through, and the second installation opening 1012 is for the speaker 3 to pass through. The cover plate 102 is connected to the frame body 101 and encloses a first sound cavity 11 and a second sound cavity 12.

[0049] When assembling the audio module 10, first install the earpiece 2 into the frame 101 through the first installation port 1011, and install the speaker 3 into the frame 101 through the second installation port 1012; then, connect the cover 102 to the frame 101, and use the cover 102 to block the first installation port 1011 and the second installation port 1012, so that the first sound cavity 11 and the second sound cavity 12 are enclosed between the cover 102 and the frame.

[0050] This facilitates the assembly of the audio module 10 , helps to improve the assembly efficiency of the audio module 10 , and reduces the cost of the audio module 10 .

[0051] Optionally, the cover plate 102 is bonded to the frame 101 .

[0052] For example, the cover plate 102 and the frame body 101 are bonded together by structural adhesive.

[0053] In some other embodiments, the cover plate 102 and the frame 101 may also be welded.

[0054] For example, the frame 101 and the cover 102 are both made of plastic, and the frame 101 and the cover 102 are welded by hot riveting.

[0055] Alternatively, if Figure 3 As shown, the first mounting opening 1011 and the second mounting opening 1012 are disposed on the same side of the frame 101 in the second direction.

[0056] By arranging the first mounting port 1011 and the second mounting port 1012 on the same side of the frame 101 , the earpiece 2 and the speaker 3 can be assembled on the same side of the frame 101 , which is beneficial to further improve the assembly efficiency of the audio module 10 and reduce the cost of the audio module 10 .

[0057] Optionally, the earpiece 2 is bonded to the frame 101 .

[0058] For example, the earpiece 2 is bonded to the frame 101 by structural adhesive.

[0059] Optionally, the speaker 3 is bonded to the frame 101 .

[0060] For example, the speaker 3 is bonded to the frame 101 by structural adhesive.

[0061] In some embodiments, Figure 2As shown, the first sound cavity 11 includes a first rear cavity 111 and a first front cavity 112 that are connected, the earpiece 2 is arranged in the first rear cavity 111, and the first front cavity 112 is arranged on one side of the first rear cavity 111 in the second direction. The second sound cavity 12 includes a second rear cavity 121 and a second front cavity 122 that are connected, the speaker 3 is arranged in the second rear cavity 121, and the second front cavity 122 is arranged on one side of the second rear cavity 121 in the second direction. The first front cavity 112 is used to enclose the front cavity of the earpiece 2, and the second front cavity 122 is used to enclose the front cavity of the speaker 3. Among them, the first rear cavity 111 is arranged on one side of the second rear cavity 121 in the first direction. The orthographic projection of a part of the second front cavity 122 in the second direction at least partially overlaps with the orthographic projection of the second rear cavity 121 in the second direction. The orthographic projection of a part of the second front cavity 122 in the second direction at least partially overlaps with the orthographic projection of the first front cavity 112 in the second direction.

[0062] For example, Figure 2 As shown, the second front cavity 122 includes a first part 1221, a second part 1222 and a third part 1223, the orthographic projection of the first part 1221 in the second direction overlaps with the orthographic projection of a part of the second rear cavity 121 in the second direction, the orthographic projection of the second part 1222 in the second direction overlaps with the orthographic projection of a part of the first front cavity 112 in the second direction, and the orthographic projection of the third part 1223 in the second direction overlaps with the orthographic projection of the partition 15 in the second direction.

[0063] It can be understood that when the volume of the second front cavity 122 is constant, the larger the area occupied by the second front cavity 122 in the first direction, the smaller the size of the second front cavity 122 in the second direction. By setting the orthographic projection of a part of the second front cavity 122 in the second direction to overlap with the orthographic projection of at least a part of the second rear cavity 121 in the second direction, and setting the orthographic projection of a part of the second front cavity 122 in the second direction to overlap with the orthographic projection of at least a part of the first front cavity 112 in the second direction, the area occupied by the second front cavity 122 in the first direction is larger, so that the size of the second front cavity 122 in the second direction can be reduced, thereby reducing the size of the bracket 1 in the second direction, and reducing the size of the audio module 10 in the second direction.

[0064] For example, when the second direction is the thickness direction of the audio module 10, by performing the above-mentioned design on the second front cavity 122, the thickness of the audio module 10 can be reduced, and the space occupied by the audio module 10 in the thickness direction can be reduced.

[0065] Optionally, the first front cavity 112 and the second front cavity 122 are arranged on the same side of the first front cavity 112 in the second direction. The orthographic projection of the first front cavity 112 in the second direction is entirely located within the orthographic projection of the first rear cavity 111 in the second direction. In other words, the cross-sectional area of ​​the first front cavity 112 is smaller than the cross-sectional area of ​​the first rear cavity 111. The cross-sectional area of ​​the first front cavity 112 refers to the cross-sectional area of ​​the first front cavity 112 cut by a plane perpendicular to the second direction. The cross-sectional area of ​​the first rear cavity 111 refers to the cross-sectional area of ​​the first rear cavity 111 cut by a plane perpendicular to the second direction.

[0066] By arranging the first front cavity 112 and the second front cavity 122 on the same side of the first front cavity 112 in the second direction, it is beneficial to further improve the compactness of the layout of the first sound cavity 11 and the second sound cavity 12, thereby further reducing the occupied space of the audio module 10.

[0067] Alternatively, if Figure 4 As shown, the bracket 1 is provided with a first communication port 13 and a second communication port 14, the first communication port 13 is communicated with the first front cavity 112, and the second communication port 14 is communicated with the second front cavity 122. The first communication port 13 and the second communication port 14 are provided on different sides of the bracket 1.

[0068] For example, Figure 4 As shown, the first communication port 13 is provided on one side of the bracket 1 in the second direction, and the second communication port 14 is provided on the third direction ( Figure 4 The third direction, the second direction and the first direction are orthogonal to each other.

[0069] It is understandable that the first communication port 13 and the second communication port 14 are formed by opening holes on the bracket 1, and opening holes on the bracket 1 will affect the structural strength of the bracket 1. By arranging the first communication port 13 and the second communication port 14 on different sides of the bracket 1, it is possible to avoid opening more holes on the same side of the bracket 1, which is beneficial to improving the structural strength of the bracket 1 and improving the reliability of the audio module 10.

[0070] In addition, in the related art, the sound outlet of the earpiece and the sound outlet of the speaker of the terminal device with an audio module are usually arranged on the same side of the terminal device. By arranging the first communication port 13 and the second communication port 14 on different sides of the bracket 1, the first communication port 13 can be connected to the sound outlet of the earpiece, and the second communication port 14 can be connected to the sound outlet of the speaker from different sides of the bracket 1, thereby facilitating the connection between the earpiece 2 and the speaker 3 and the corresponding sound outlets.

[0071] Optionally, the earpiece 2 and the first sound cavity 11 form a back cavity of the earpiece 2 , and the back cavity of the earpiece 2 is at least partially annular and is arranged around the earpiece 2 .

[0072] For example, the outer circumferential surface of the earpiece 2 and the cavity wall of the first sound cavity 11 form a back cavity of the earpiece 2 , and the back cavity of the earpiece 2 is annular as a whole and is arranged around the earpiece 2 .

[0073] It can be understood that when the volume of the back cavity of the earpiece 2 is constant, the larger the area occupied by the back cavity of the earpiece 2 in the first direction, the smaller the size of the back cavity of the earpiece 2 in the second direction, and the size of the bracket 1 in the second direction. By designing the first sound cavity 11 and the back cavity of the earpiece 2 as above, it is helpful to further reduce the size of the bracket 1 in the second direction and reduce the size of the audio module 10 in the second direction.

[0074] Optionally, the speaker 3 and the second sound cavity 12 form a back cavity of the speaker 3 , and the back cavity of the speaker 3 is at least partially annular and is arranged around the speaker 3 .

[0075] For example, the outer peripheral surface of the loudspeaker 3 and the cavity wall of the second sound cavity 12 form a back cavity of the loudspeaker 3 , and the back cavity of the loudspeaker 3 is annular as a whole and is arranged around the loudspeaker 3 .

[0076] It can be understood that when the volume of the rear cavity of the speaker 3 is constant, the larger the area occupied by the rear cavity of the speaker 3 in the first direction, the smaller the size of the rear cavity of the speaker 3 in the second direction, and the size of the bracket 1 in the second direction. By designing the second sound cavity 12 and the rear cavity of the speaker 3 as above, it is helpful to further reduce the size of the bracket 1 in the second direction and reduce the size of the audio module 10 in the second direction.

[0077] In some embodiments, Figure 1 , Figure 3 and Figure 4 As shown, the audio module 10 also includes an antenna 4 , which is connected to the bracket 1 .

[0078] By connecting the antenna 4 to the bracket 1, the bracket 1 also serves as a mounting carrier for the antenna 4, thereby further reducing the number of mounting carriers and further reducing the space occupied by the audio module 10.

[0079] Optionally, the bracket 1 is an insulating bracket.

[0080] For example, the bracket 1 is a plastic bracket.

[0081] By setting the bracket 1 as an insulating bracket, on the one hand, it is possible to prevent the bracket 1 from affecting the performance of the antenna 4, and on the other hand, it is possible to avoid providing an insulating layer on the bracket 1 to achieve insulation between the antenna 4 and the bracket 1. In this way, the cost of the audio module 10 can be reduced while ensuring the performance of the antenna 4.

[0082] Optionally, the antenna 4 is formed by a thin layer of metal attached to the surface of the bracket 1. The antenna 4 is formed on the bracket 1 by printing, chemical plating and other processes.

[0083] Alternatively, if Figure 3 and Figure 4 As shown, the bracket 1 includes a first surface 103, a side surface 104 and a second surface 105 connected in sequence, and the first surface 103 and the second surface 105 are arranged opposite to each other. A part of the antenna 4 is arranged on the first surface 103, a part of the antenna 4 is arranged on the side surface 104, and another part of the antenna 4 is arranged on the second surface 105.

[0084] By arranging the antenna 4 in the above-mentioned form, the arrangement of the antenna 4 is made more compact, which is beneficial to reducing the space occupied by the antenna 4 and further reducing the space occupied by the audio module 10.

[0085] like Figures 5 to 9 As shown, the terminal device 100 of the embodiment of the present disclosure includes a middle frame 20 and an audio module 10, the audio module 10 is the audio module 10 described in any of the above embodiments, and the bracket 1 is connected to the middle frame 20. The middle frame 20 is provided with a first sound outlet channel 201 and a second sound outlet channel 202, the first sound cavity 11 is connected to the first sound outlet channel 201, and the second sound cavity 12 is connected to the second sound outlet channel 202. Among them, the terminal device 100 can be a mobile phone, a tablet computer, etc.

[0086] By providing a first sound outlet channel 201 communicating with the first sound cavity 11 , the sound outlet effect of the earpiece 2 is achieved; by providing a second sound outlet channel 202 communicating with the second sound cavity 12 , the sound outlet effect of the speaker 3 is achieved.

[0087] Since the audio module 10 of the above embodiment has low assembly complexity and occupies little space, the terminal device 100 of the embodiment of the present disclosure has low assembly cost and high internal space utilization.

[0088] Alternatively, if Figures 7 to 9 As shown, the middle frame 20 includes a main body 203 and a frame 204 . The frame 204 is disposed around the main body 203 and connected to the main body 203 . The first sound outlet channel 201 and the second sound outlet channel 202 are both disposed in the main body 203 .

[0089] It is understandable that the main body 203 is generally larger in structural strength and size than the frame 204 . By arranging the first sound outlet channel 201 and the second sound outlet channel 202 in the main body 203 , the structural strength of the middle frame 20 can be better guaranteed and the reliability of the terminal device 100 can be improved.

[0090] Alternatively, if Figure 5 and Figure 8As shown, the frame portion 204 is provided with a sound outlet hole 2041 , and the sound outlet hole 2041 is communicated with the second sound outlet channel 202 .

[0091] By providing a sound outlet hole 2041 in the frame portion 204 , the sound of the speaker 3 can be transmitted from the inside of the terminal device 100 to the outside.

[0092] Alternatively, if Figure 5 and Figure 8 As shown, there are multiple sound outlet holes 2041 , and the multiple sound outlet holes 2041 are arranged at intervals along the first direction.

[0093] By setting the number of the sound outlet holes 2041 to be multiple, it is beneficial to increase the sound outlet area of ​​the speaker 3.

[0094] Alternatively, if Figure 5 and Figure 8 As shown, the terminal device 100 also includes a display screen 30, which is arranged on one side of the thickness direction of the middle frame 20, and a gap 2042 is formed between the display screen 30 and the frame portion 204, and the gap 2042 is connected to the first sound outlet channel 201, wherein the first direction is consistent with the thickness direction of the middle frame 20.

[0095] By forming a gap 2042 between the display screen 30 and the frame portion 204 and connecting the gap 2042 with the first sound outlet channel 201, the sound of the earpiece 2 can be transmitted from the inside of the terminal device 100 to the outside, and it is possible to avoid opening a hole in the middle frame 20, which is beneficial to improving the structural strength of the middle frame 20, thereby further improving the reliability of the terminal device 100.

[0096] like Figure 5 , Figure 6 , Figure 8 and Fig. 9 As shown, the terminal device 100 further includes a back cover 40, which is disposed on the other side of the thickness direction of the middle frame 20. The back cover 40 is connected to the middle frame 20 and encloses a module installation cavity, and the audio module 10 is disposed in the module installation cavity. The back cover 40 is also a battery cover of the terminal device 100.

[0097] For example, the middle frame 20 is provided with a mounting groove, and the rear cover 40 and the middle frame 10 are surrounded by the mounting groove to form a module mounting cavity.

[0098] Alternatively, if Figure 8 As shown, the terminal device 100 includes a first sealing member 50 , which is arranged around the first sound outlet channel 201 , and the first sealing member 50 is clamped between the bracket 1 and the middle frame 20 .

[0099] The first sealing member 50 is a rubber ring, a silicone ring or other sealing rings. The first sealing member 50 may also be a foam material of a foam substrate.

[0100] By setting the first sealing member 50, sealing between the bracket 1 and the middle frame 20 can be achieved at the first sound outlet channel 201, thereby preventing impurities or water vapor entering the first sound outlet channel 201 from entering the interior of the terminal device 100 through the gap between the bracket 1 and the middle frame 20, which is beneficial to further improve the reliability of the terminal device 100.

[0101] Alternatively, if Figure 8 and Fig. 9 As shown, the terminal device 100 includes a second sealing member 60 , which is arranged around the second sound outlet channel 202 , and the second sealing member 60 is clamped between the bracket 1 and the middle frame 20 .

[0102] The second sealing member 60 is a rubber ring, a silicone ring or other sealing rings. The second sealing member 60 can also be made of a foam material with a foam substrate.

[0103] By setting the second sealing member 60, sealing between the bracket 1 and the middle frame 20 can be achieved at the second sound outlet channel 202, thereby preventing impurities or water vapor from entering the second sound outlet channel 202 and entering the interior of the terminal device 100 through the gap between the bracket 1 and the middle frame 20, which is beneficial to further improve the reliability of the terminal device 100.
