The case 11 may include a bottom plate 111 and a side plate 112 connected, and the first sound through hole a1 may be located in the side plate 112. Note that, a top view of the terminal device 10 shown in fig. 3 is a direction perpendicular to the plate surface of the base plate 111 in a top view direction f1 in fig. 2. Fig. 3 also shows an exploded view of a part of the structure of the terminal device 10, so as to more clearly show the positional correspondence of the sectional view with the respective structures.

The middle frame 12 may be connected to the outer shell 11, and further, the middle frame 12 may be fixedly connected to the outer shell 11 by a bolt connection or an adhesive connection.

As shown in fig. 4 and 5, fig. 4 is a schematic structural diagram of the crimping bracket 15, the center 12, and the acoustic channel assembly 14 in the terminal device shown in fig. 1, and fig. 5 is a schematic structural diagram of the center 12 and the acoustic channel assembly 14 in the terminal device shown in fig. 1. The middle frame 12 may have a mounting through hole 121, the mounting through hole 121 may be capable of penetrating the middle frame 12, and the acoustic channel assembly 14 may be located at the mounting through hole 121. The shape of the acoustic channel assembly 14 may be matched with the shape of the inner side surface of the mounting through hole 121, so that at least a portion of the acoustic channel assembly 14 is embedded in the mounting through hole 121, and the acoustic channel assembly 14 may be attached to the inner side surface of the mounting through hole 121 to form a sealing structure, thereby preventing impurities such as dust in the external environment from entering the interior of the terminal device 10 from the contact position of the acoustic channel assembly 14 and the middle frame 12. It should be noted that, in fig. 5, only the acoustic channel housing 141 of the acoustic channel assembly 14 is shown, and the sealing structures (e.g., the first gasket 142 and the third gasket) of the acoustic channel assembly 14 are not shown, in order to clearly show the structural positional relationship between the acoustic channel assembly 14 and the middle frame 12.

And the crimping bracket 15 may abut against the acoustic channel assembly 14 to crimp the acoustic channel assembly 14 against the housing 11 to achieve a secure mounting of the acoustic channel assembly 14 in the housing 11. In this manner, the difficulty of mounting or dismounting the acoustic channel assembly 14 can be reduced, so that the acoustic channel assembly 14 can be separately dismounted for replacement or repair when the acoustic channel assembly 14 is damaged. For example, when the sound channel a2 is clogged or damaged, the acoustic channel assembly 14 may be detached from the terminal device 10 to perform maintenance on the speaker channel. Since there are few other structures connected to the acoustic channel assembly 14 and the acoustic channel assembly 14 abuts on the housing 11 by the crimping bracket 15, the acoustic channel assembly 14 is less difficult to detach, and repair or replacement of the acoustic channel assembly 14 can be made less difficult.

The first gasket 142 may be located outside the acoustic channel case 141 and surround the first opening a21. The first gasket 142 may be an annular gasket, the first opening a21 may be located in an inner ring of the annular gasket, and the first gasket 142 may be located in a gap between the acoustic channel case 141 and the outer case 11. The crimping bracket 15 may abut against the acoustic channel case 141 so that the acoustic channel case 141 presses the first gasket 142 against the housing 11. As such, the crimping bracket 15 may apply a pressure to the acoustic channel case 141 toward the housing 11 to press the first gasket 142 by the acoustic channel case 141 and the housing 11, deforming the first gasket 142 to form a seal between the acoustic channel case 141 and the housing 11. Moreover, the vibration generated by the audio element 13 during operation can be effectively absorbed by the first sealing gasket 142, so that the vibration phenomenon of the whole terminal device 10 can be reduced, and the experience of the user can be improved.

In the related art, in the process of assembling the sealing gasket between the middle frame and the shell, the middle frame can be embedded into the shell along the direction perpendicular to the bottom plate of the shell so as to assemble the middle frame inside the shell, so that the sealing gasket attached to the surface of the middle frame is easily scratched by the shell in the process of embedding the middle frame, and the reliability of sealing and water proofing of the first sealing gasket is low. Therefore, when the gasket is positioned in the gap between the middle frame and the shell, the requirement on the installation precision of the middle frame and the shell in the process of contraposition bonding is high, and the installation difficulty is increased. In the embodiment of the present invention, through independently setting the sound channel component 14, it is compared with the sound channel a2 in the related art that is located in the middle frame 12, so that the extrusion force received by the first sealing gasket 142 is large.

The slopes of the first slope C1 and the second slope C2 may be the same, and the first slope C1 and the second slope C2 may be attached. In this manner, the crimping bracket 15 may apply a pressing force toward the side plate 112 to the acoustic channel case 141 through the mounting portion 152 to press the first gasket 142 by the acoustic channel case 141 and the housing 11, deforming the first gasket 142 to form a seal between the acoustic channel case 141 and the housing 11.

In this manner, by filling the first gasket 142 in the gap between the acoustic channel housing 141 and the circuit board 17 with interference, the possibility of sound leakage can be reduced, so that the sealing effect of the terminal device 10 is better. Moreover, the second gasket 143 can be better fixed, and the second gasket 143 is prevented from being displaced during the assembling process.

Alternatively, as shown in fig. 7, the first inclined plane C1 of the acoustic channel case 141 and the bottom plate 111 of the housing 11 may have an angle ranging from 40 ° to 50 °. In this manner, it is possible to make the crimping bracket 15 capable of applying a pressing force to the acoustic channel case 141 toward the side plate 112 of the housing 11, and at the same time, the crimping bracket 15 capable of applying a pressing force to the acoustic channel case 141 toward the bottom plate 111 of the housing 11.

Optionally, as shown in fig. 11, the acoustic channel assembly 14 may further include a sealing net 146, and the sealing net 146 is located outside the acoustic channel housing 141 and covers the first opening of the sound passage. The sealing mesh 146 may cover the first opening of the sound passage on the side facing the housing 11. Therefore, impurities such as external dust can be effectively prevented from entering the sound channel, and further the impurities such as the external dust can be prevented from entering the audio element. Exemplarily, the dust screen can effectively prevent external dust or water drops from entering the loudspeaker, and can prevent sharp objects such as a clamping needle from being mistakenly inserted into the sound channel.

To sum up, the embodiment of the utility model provides a terminal equipment, include: the audio device comprises a shell, a middle frame, an audio element, an audio channel assembly and a crimping support. Wherein, having the installation through-hole in the center, having the sound channel in the sound channel subassembly, the sound channel subassembly is located the installation through-hole of center, so, has simplified the structure of center through the mode of independently setting up the sound channel, has reduced the manufacturing degree of difficulty of center.

In addition, the crimping support is connected with the center, and with the sound channel subassembly butt to press the sound channel subassembly on the shell, can reduce the installation of sound channel subassembly or the degree of difficulty of dismantling.
