As shown in Figure 4 or Figure 5 , the receiving hole 14 and the second sound outlet channel 13 are both formed on the shell 1, specifically on the side wall part of the middle frame 15.
[0046] Exemplarily, as shown in Figure 6 or Figure 7 , the electronic device further comprises a screen assembly 4, which is installed on one side in the thickness direction of the shell 1, and the shell 1 further comprises a decorative piece 16, which is connected with one side in the thickness direction of the middle frame 15, and the decorative piece 16 is located at the periphery of the screen assembly 4, and the gap between the screen assembly 4 and the decorative piece 16 constitutes the first sound outlet channel 12, which is used as a receiver sound outlet channel, while the second sound outlet channel 13 is used as an external speaker sound outlet channel.
[0047] Specifically, the loudspeaker 2 is installed in the containing cavity 11 and located at the top of the electronic device, and the loudspeaker 2 is used as the upper loudspeaker of the electronic device. It can be understood that the top of the electronic device is located on one side in the length direction of the electronic device.

Figure 7
[0053] The electronic device provided by the embodiments of the present application can change the communication state of the second sound outlet channel 13 and the accommodating cavity 11 by setting the switch assembly 3, using the movement of the dialing piece 32 to drive the movable shielding piece 31 to move relative to the shell 1; when the user needs to play sound externally, the user only needs to dial the dialing piece 32 to one side, so that the first end of the second sound outlet channel 13 communicates with the accommodating cavity 11, that is, the second sound outlet channel 13 is opened, so that the sound propagates along the second sound outlet channel 13 to the external environment, ensuring that the external volume and the external sound effect meet the needs; when the user needs private conversation, the user only needs to dial the dialing piece 32 to the other side, so that the first end of the second sound outlet channel 13 is separated from the accommodating cavity 11, that is, the second sound outlet channel 13 is closed, at this time, the sound only propagates along the first sound outlet channel 12 to the user's ear, and the surrounding people are difficult to hear the conversation content, thereby fully ensuring the user's conversation privacy and safety, and helping to improve the user's use experience.
[0054] In a further embodiment, the switch assembly 3 further comprises a bracket 33, the bracket 33 is installed in the accommodating cavity 11, the bracket 33 is annular and surrounds the first end of the second sound outlet channel 13, and the movable shielding piece 31 is movably connected with the bracket 33.

Specifically, the movable shielding piece 31 is located on the side of the fixed shielding piece 34 close to the accommodating cavity 11, and the movable shielding piece 31 can move relative to the fixed shielding piece 34 along the length direction of the support 33, so that the first through hole 341 and the second through hole 311 move relatively, the overlapping degree of the first through hole 341 and the second through hole 311 is changed, and then the communication state of the second sound outlet channel 13 and the accommodating cavity 11 is changed.
[0060] Specifically, when the movable shielding piece 31 is in the first limit position, the first through hole 341 and the second through hole 311 are completely misaligned. At this time, the movable shielding piece 31 and the fixed shielding piece 34 block the first end of the second sound outlet channel 13, the second sound outlet channel 13 and the accommodating cavity 11 are separated from each other, and the sound emitted by the loudspeaker 2 cannot be transmitted to the outside of the electronic device through the second sound outlet channel 13. When the movable shielding piece 31 is in the second limit position, the first through hole 341 and the second through hole 311 overlap. At this time, the first end of the second sound outlet channel 13 is opened, the second sound outlet channel 13 is in full communication with the accommodating cavity 11, and the sound emitted by the loudspeaker 2 can be transmitted to the outside of the electronic device through the second sound outlet channel 13.

[0063] By arranging the first back adhesive layer 35, not only the reliable connection of the fixed shielding piece 34 and the support 33 is realized, but also the waterproof effect of the switch assembly 3 is improved to some extent.
[0064] In a specific embodiment, the first through hole 341 and the second through hole 311 are both a plurality of, and the plurality of first through holes 341 and the plurality of second through holes 311 can be one-to-one correspondingly overlapped.
[0065] As shown in Figure 2 or Figure 3 The first through hole 341 and the second through hole 311 are both a plurality of. As shown inFigure 5 As shown, when the movable shield 31 is in the second limit position, the plurality of first through holes 341 and the plurality of second through holes 311 can one-to-one correspondingly overlap.
[0066] Through the arrangement, when the second sound outlet channel 13 communicates with the accommodating cavity 11, the opening degree of the first end of the second sound outlet channel 13 is improved, and it is ensured that the sound effect and the sound volume of the electronic device meet the requirements.
[0067] The shapes of the first through holes 341 and the second through holes 311 can be circular, quadrilateral, triangular, oval or other shapes, and the shapes and sizes of the first through holes 341 and the second through holes 311 can be the same or different.
[0068] In a specific embodiment, the shape and size of the first through hole 341 are respectively matched with the shape and size of the second through hole 311.
[0069] For example Figure 2 Or Figure 3 As shown, the first through hole 341 and the second through hole 311 are both circular holes, and the size of the first through hole 341 is the same as that of the second through hole 311.
[0070] Wherein, the sizes of the first through hole 341 and the second through hole 311 can be set according to actual requirements, for example, the sum of the opening areas of the plurality of first through holes 341 and the sum of the opening areas of the plurality of second through holes 311 are respectively 8-15 square millimeters.
