In an exemplary embodiment, as shown in fig. 1-2, the sound transmission channel 2 is used to define the propagation direction of the sound wave, ensuring that the sound wave can propagate along the design direction to realize different functions of the terminal device. For example, the first channel 21 extends along a planar direction of the terminal device, and the first channel 21 and the second channel 22 have a predetermined included angle along a thickness direction of the terminal device (refer to a Z-axis direction shown in fig. 1 and 2). And the plane direction of the terminal equipment is parallel to the display screen of the terminal equipment.
In one example, when the preset angle is the first preset angle, the second channel 22 is directed to the side of the terminal device. The first predetermined included angle is, for example, 150 to 180.

The connecting bracket 4 is provided with a through channel 41, and the through channel 41 corresponds to the first channel 21 and the second channel 22 of the sound transmission channel 2. When the sound wave in the sound transmission channel 2 propagates from the first channel 21 to the second channel 22, the sound wave propagates to the connecting support 4 and can propagate into the second channel 22 through the through channel 41, so that the propagation of the sound wave is prevented from being blocked.
In one example, the connecting bracket 4 is, for example, a plate shape, has a simple structure, and has an unlimited outer peripheral shape, and does not need to be attached to the exterior of the terminal device, as long as it is disposed on the sound transmission duct 2, and can be mounted with the dust-proof portion 3.

The coverage area of the first dust-proof layer 31 may be smaller than the radial cross-sectional area of the sound transmission channel 2, as long as the penetrating channel 41 can be shielded.
The second dust-proof layer 32 can also be hung on the second surface 43 of the connecting bracket 4, and the covering area of the second dust-proof layer 32 also completely covers the through channel 41 to isolate the liquid foreign objects and prevent the liquid foreign objects from entering the horn unit 1. Wherein, the coverage area of the second dust-proof layer 32 can be the same as that of the first dust-proof layer 31.

The sound emitting passage 511 forms an equal diameter passage along the extending direction of the sound emitting passage 511.
Of course, it will be understood that the radial cross-sectional shape of sound outlet passage 511 may be different from its port shape. For example, the port of the sound outlet channel 511 communicating with the second channel 22 is a second port, the radial cross-sectional area of the second port is smaller than the radial cross-sectional area of the sound outlet channel 511, and the radial cross-sectional area of the sound outlet channel 511 is smaller than the radial cross-sectional area of the first port. Along the extending direction of the sound outlet channel 511, the sound outlet channel 511 forms a diameter-variable channel, so as to further improve the audio effect of the terminal device.

The vertical section 522 may be perpendicular to the side wall of the first support 51 so that the sound wave propagates in the designed direction. The second dust proof layer 32 is located in the second passage 22 and covers the port of the first passage 21.
In order to make the connection between the second support 52 and the housing 6 more reliable, the second support 52 is bonded to the housing 6, for example, in a dispensing manner, so as to avoid deviation of the first channel 21 and the second channel 22, which affects normal propagation of the sound wave. The sound emitting side of the horn unit 1 is disposed corresponding to the horizontal section 521 of the second bracket 52 so that the sound wave of the horn unit 1 can propagate along the first passage 21 toward the second passage 22. And the sound emitting channel 511 is disposed corresponding to the vertical section 522 so that the sound waves in the second channel 22 can propagate along the sound emitting channel 511 to the outside of the terminal device.
In an exemplary embodiment, as shown in fig. 1-2, the first bracket 51 includes a first sub-bracket (not shown) and a second sub-bracket (not shown), and the first sub-bracket and the second sub-bracket are detachably connected.

When the dust screen is damaged, the maintenance steps are simplified, and the maintenance efficiency is improved.
In another example, the dust-proof net may be a separate structure, and the dust-proof net is in one-to-one correspondence with the sound-emitting channels 511 and separates the sound-emitting channels 511 respectively. When the dust screen is damaged, the dust screen can be replaced pertinently, and the maintenance cost is saved.
