When the number of the sound outlets 501 is plural, the sound outlet channel 500 includes a main channel and a plurality of branch channels communicating with the main channel, the main channel communicates with the first cavity 413 through the second opening 412, the plurality of branch channels all communicate with the main channel, and each branch channel is provided with one sound outlet 501, so that the sound emitted by the sound emitting device 420 can be emitted through the sound outlets 501 at a plurality of different positions. Both the main channel and the branch channel may be set by any one of the six setting cases of the sound outlet channel 500 when the number of the sound outlets 501 is one.

Illustratively, as shown in fig. 3, at least one sound outlet 501 of the sound channel 500 is located between the first structural member 100 and the rim 220. Thus, when the first structural member 100 is the first display screen, the sound is emitted through the sound outlet 501 between the first display screen and the frame 220, so that the sound is emitted in a direction perpendicular to the first display screen. This kind of setting method is applicable to the condition that uses sound structure 400 as the earphone, and sound structure 400 installs on terminal equipment's top, and in the conversation, the user is close to the ear with terminal equipment's top part of first display screen, and the sound of passing out via sound outlet 501 can more direct get into user's ear, reduces the condition of leaking sound, and conversation privacy is higher.

In one implementation, as shown in fig. 11, the sound outlet channel 500 is partially located in the frame 220, partially located between the frame 220 and the first structural member 100, the second opening 412 is disposed along the X-axis direction, the sound outlet channel 500 includes a first channel 510 and a second channel 520, the first channel 510 is communicated with the second channel 520, the second channel 520 is disposed along the X-axis direction in an extending manner, the first channel 510 is disposed along the Z-axis direction in an extending manner, and the sound outlet 501 is located at one end of the first channel 510 far away from the second channel 520. In this arrangement, the first channel 510 and the second channel 520 are perpendicular to each other, the total length of the first channel 510 and the second channel 520 is shorter, and the path of sound passing through the sound outlet channel 500 is shorter, so that the sound passes out of the sound outlet structure 400 to the outside of the terminal device faster.

In some implementations, as shown in fig. 12, the sound outlet channel 500 is partially located between the frame 220 and the first structural member 100, and the sound outlet channel 500 includes a first channel 510 and a second channel 520, where the first channel 510 extends along the Z-axis, one end of the first channel 510 that communicates with the sound outlet 501 is located between the frame 220 and the first structural member 100, the other end of the first channel 510 communicates with the second channel 520, one end of the first channel 510 that communicates with the second channel 520 is located inside the frame 220, the second channel 520 is disposed on the frame 220, one end of the second channel 520 that is far away from the first channel 510 communicates with the second opening 412 of the housing 410, and the second channel 520 is disposed obliquely with respect to the Z-axis. In fig. 12, the distance between the second channel 520 and the third structural member 300 decreases gradually from one end of the second channel 520 communicating with the second opening 412 to the other end, i.e. the second opening 412 is arranged obliquely with respect to the third structural member 300. The inclined arrangement of the second channels 520 may result in a larger area of the second channels 520 in a cross section parallel to the Z-axis, i.e. a larger passage area for the air flow.

In some implementations, as shown in fig. 13, the audio channel 500 further includes a third channel 530, the third channel 530 is disposed in the frame 220, the first channel 510 and the second channel 520 are communicated through the third channel 530, the third channel 530 is located between the first channel 510 and the second channel 520, the first channel 510 extends along the first direction, and the third channel 530 is disposed obliquely opposite to the first channel 510 and the second channel 520, respectively. The third channel 530 has a transition effect between the first channel 510 and the second channel 520, and since the end of the first channel 510 is the sound outlet 501 and the size of the sound outlet 501 in the X-axis direction is relatively narrow, the size of the first channel 510 in the X-axis direction is relatively small, and in order to reduce the extension length of the first channel 510 (i.e., the size in the Z-axis direction), the first channel 510 and the second channel 520 are communicated through the third channel 530, one end of the third channel 530 is communicated with the second channel 520, and the other end of the third channel 530 extends obliquely upward with respect to the third structural member 300 and is communicated with the first channel 510, so that the size of the first channel 510 in the Z-axis direction can be reduced. The distance between the third channel 530 and the third structural member 300 increases gradually from one end of the third channel 530 communicating with the second channel 520 to the other end. The airflow passing area of the third passage 530 is larger than that of the first passage 510. The air flow passage area is the opening area of the corresponding passage in a section perpendicular to the extending direction of the passage. For example, the airflow passing area of the first passage 510 is the opening area of the first passage 510 in a cross section perpendicular to the Z axis.

In some implementations, as shown in fig. 3 and fig. 13, the terminal device further includes a plug 230, as shown in fig. 8, where the frame 220 is further provided with a fourth channel 540, the fourth channel 540 and the third channel 530 extend in the same direction, one end of the fourth channel 540 is communicated with the third channel 530, the third structural member 300 covers the other end of the fourth channel 540, and the plug 230 is blocked in the fourth channel 540.

Because the third channel 530 and the first channel 510 are disposed obliquely, and the third channel 530 and the second channel 520 are disposed obliquely, and the third channel 530 is located between the first channel 510 and the second channel 520, that is, both ends of the third channel 530 do not leak out of the frame 220, in order to facilitate processing of the third channel 530, a fourth channel 540 is disposed on the frame 220, the extending directions of the fourth channel 540 and the third channel 530 are the same, and one end of the fourth channel 540 is exposed out of the side surface of the frame 220, in particular, the frame 220 faces one side of the third structural member 300. Only in the processing process, a channel can be formed from the side of the frame 220 facing the third structural member 300 from outside to inside, the channel is respectively communicated with the first channel 510 and the second channel 520, after the plugging block 230 is plugged in the channel, the part of the plugging block 230 which is not plugged is the third channel 530, and the part for accommodating the plugging block 230 is the fourth channel 540. The plugging block 230 is used for plugging an end opening of the fourth channel 540 facing the third structural member 300.

In some implementations, as shown in fig. 13, the number of the sound outlets 501 of the sound outlet channel 500 is two, and the sound outlet channel 500 further includes a fifth channel 550, where the second channel 520 is respectively communicated with the first channel 510 and the fifth channel 550, and the other end of the first channel 510 and the other end of the fifth channel 550 are respectively communicated with the sound outlets 501. So configured, sound emanating from the sound emanating structure 400 may emanate in two different directions. The setting mode is more suitable for the top end of the terminal equipment.

As shown in fig. 14, the fifth channel 550 is disposed on the frame 220, the fifth channel 550 extends along the X-axis direction, and one end of the fifth channel 550 is communicated with the second channel 520, and the other end is the sound outlet 501, which is communicated with the outside of the terminal device. In this arrangement, the sound emitted by the sound emitting structure 400 enters the second channel 520 through the first cavity 413, and a part of the sound enters the first channel 510 through the second channel 520 and propagates in the first channel 510 along the Z-axis direction, so that the sound emitted by the first channel 510 is more suitable for the user to perform voice communication, so that the sound is directly transmitted into the ear of the user; another part of sound enters the fifth channel 550 through the second channel 520 and propagates in the fifth channel 550 along the X-axis direction, and the sound emitted through the fifth channel 550 is more suitable for the user to use the sound playing function of the terminal device, and the size of the sound outlet 501 of the fifth channel 550 may be larger than the size of the sound outlet 501 of the first channel 510, so that the sound played by the fifth channel 550 can be louder and clearer.

In some implementations, as shown in fig. 15, the sound outlet 500 has a sound outlet 501, the sound outlet 501 is located on the frame 220, the sound outlet 500 includes a second channel 520 and a fifth channel 550, the second channel 520 communicates with the second opening 412, the fifth channel communicates with the second channel 520 and the sound outlet 501, and the first channel 510 and the second channel 520 are disposed obliquely relative to each other.

The second sealing structure 620 may be a sealing ring made of elastic materials such as rubber, silica gel, etc., or foam, back glue, etc., or a combination of any of the above. The provision of the second sealing structure 620 improves the sealing performance between the first structural member 100 and the housing 410, and reduces or even avoids sound from being transmitted between the first structural member 100 and the housing 410, so that more sound enters the sound outlet channel 500 through the second opening 412, and the volume of sound emitted through the sound outlet 501 of the sound outlet channel 500 is improved.

In some embodiments, as shown in fig. 1 and 16, the sound outlet channel 500 is at least partially located in the second structural member 200, the sound inlet of the sound outlet channel 500 is located in the second structural member 200, the side surface of the housing 410 provided with the second opening 412 is opposite to the side surface of the second structural member 200 provided with the sound inlet, and the dust-proof member 700 is provided between the housing 410 and the second structural member 200, and the dust-proof member 700 may be a dust-proof net, which may be used to block dust so as to reduce or even avoid dust from entering the first cavity 413, and the dust-proof level may be adjusted by adjusting the mesh size of the dust-proof net, that is, the mesh opening is smaller, so that dust with smaller size may be blocked, and the dust-proof net may also play a role in certain waterproofing.
